Simple animals could live in Martian brines: Wikinews interviews planetary scientist Vlada Stamenkovi?

Wednesday, January 9, 2019

Planetary scientist Vlada Stamenkovi? of the NASA Jet Propulsion Laboratory and colleagues have developed a new chemical model of how oxygen dissolves in Martian conditions, which raises the possibility of oxygen-rich brines; enough, the work suggests, to support simple animals such as sponges. The model was published in Nature on October 22. Wikinews caught up with him in an email interview to find out more about his team’s research and their plans for the future.

The atmosphere of Mars is far too thin for humans to breathe or for lungs like ours to extract any oxygen at all. It has on average only around 0.6% of the pressure of Earth’s atmosphere, and this is mainly carbon dioxide; only 0.145% of the thin Martian atmosphere is oxygen. The new model indicated these minute traces of oxygen should be able to enter salty seeps of water on or near the planet’s surface at levels high enough to support life forms comparable to Earth’s microbes, possibly even simple sponges. Some life forms can survive without oxygen, but oxygen permits more energy-intensive metabolism. Almost all complex multicellular life on Earth depends on oxygen.

“We were absolutely flabbergasted […] I went back to recalculate everything like five different times to make sure it’s a real thing,” Stamenkovi? told National Geographic.

“Our work is calling for a complete revision for how we think about the potential for life on Mars, and the work oxygen can do,” he told Scientific American, “implying that if life ever existed on Mars it might have been breathing oxygen”.

Stamenkovi? et al cite research from 2014 showing some simple sponges can survive with only 0.002 moles of oxygen per cubic meter (0.064 mg per liter). Some microbes that need oxygen can survive with as little as a millionth of a mole per cubic meter (0.000032 mg per liter). In their model, they found there can be enough oxygen for microbes throughout Mars, and enough for simple sponges in oases near the poles.

In 2014, also suggesting multicellular life could exist on Mars, de Vera et al, using the facilities at the German Aerospace Center (DLR), studied some lichens, including Pleopsidium chlorophanum, which can grow high up in Antarctic mountain ranges. They showed those lichens can also survive and even grow in Mars simulation chambers. The lichens can do this because their algal component is able to produce the oxygen needed by the fungal component. Stamenkovi? et al’s research provides a way for oxygen to get into the Martian brines without algae or photosynthesis.

Stamenkovi? et al found oxygen levels throughout Mars would be high enough for the least demanding aerobic (oxygen-using) microbes, for all the brines they considered, and all the methods of calculation. They published a detailed map[3] of the distributions of solubility for calcium perchlorates for their more optimistic calculations, which they reckoned were closer to the true case, with and without supercooling. The lowest concentrations were shown in the tropical southern uplands. Brine in regions poleward of about 67.5° to the north and about 72.5° to the south could have oxygen concentrations high enough for simple sponges. Closer to the poles, concentrations could go higher, approaching levels typical of sea water on Earth, 0.2 moles per cubic meter (6.4 mg per liter), for calcium perchlorates. On Earth, worms and clams that live in the muddy sea beds require 1 mg per liter, bottom feeders such as crabs and oysters 3 mg per liter, and spawning migratory fish 6 mg per liter, all within 0.2 moles per cubic meter, 6.4 mg per liter.

((Wikinews)) Does your paper’s value of up to 0.2 moles of oxygen per cubic meter, the same as Earth’s sea water, mean that there could potentially be life on Mars as active as our sea worms or even fish?
Stamenkovi?: Mars is such a different place than the Earth and we still need to do so much more work before we can even start to speculate.

Stamenkovi? et al studied magnesium and calcium perchlorates, common on Mars. They found the highest oxygen concentrations occur when the water is colder, which happens most in polar regions.

((WN)) The temperatures for the highest levels of oxygen are really low, -133 °C, so, is the idea that this oxygen would be retained when the brines warm up to more habitable temperatures during the day or seasonally? Or would the oxygen be lost as it warms up? Or — is the idea that it has to be some exotic biochemistry that works only at ultra low temperatures like Dirk Schulze-Makuch’s life based on hydrogen peroxide and perchlorates internal to the cells as antifreeze?
Stamenkovi?: The options are both: first, cool oxygen-rich environments do not need to be habitats. They could be reservoirs packed with a necessary nutrient that can be accessed from a deeper and warmer region. Second, the major reason for limiting life at low temperature is ice nucleation, which would not occur in the type of brines that we study.

Stamenkovi? et al’s paper is theoretical and is based on a simplified general circulation model of the Mars atmosphere — it ignores distinctions of seasons and the day / night cycle. Stamenkovi?’s team combined it with a chemical model of how oxygen would dissolve in the brines and used this to predict oxygen levels in such brines at various locations on Mars.

When asked about plans for a future model that might include seasonal timescales, Stamenkovi? told Wikinews, “Yes, we are now exploring the kinetics part and want to see what happens on shorter timescales.”

Stamenkovi? et al’s model also takes account of the tilt of the Mars axis, which varies much more than Earth’s does.

Wikinews asked Stamenkovi? if he had any ideas about whether and how sponges could survive through times when the tilt was higher and less oxygen would be available:

((WN)) I notice from your figure[4] that there is enough oxygen for sponges only at tilts of about 45 degrees or less. Do you have any thoughts about how sponges could survive periods of time in the distant past when the Mars axial tilt exceeds 45 degrees, for instance, might there be subsurface oxygen-rich oases in caves that recolonize the surface? Also what is the exact figure for the tilt at which oxygen levels sufficient for sponges become possible? (It looks like about 45 degrees from the figure but the paper doesn’t seem to give a figure for this.)
Stamenkovi?: 45 deg is approx. the correct degree. We were also tempted to speculate about this temporal driver but realized that we still know so little about the potential for life on Mars/principles of life that anything related to this question would be pure speculation, unfortunately.
((WN)) How quickly would the oxygen get into the brines — did you investigate the timescale?
Stamenkovi?: No, we did not yet study the dynamics. We first needed to show that the potential is there. We are now studying the timescales and processes.
((WN)) Could the brines that Nilton Renno and his teams simulated, forming on salt/ice interfaces within minutes in Mars simulation conditions, get oxygenated in the process of formation? If not, how long would it take for them to get oxygenated to levels sufficient for aerobic microbes? For instance could the Phoenix leg droplets have taken up enough oxygen for aerobic respiration by microbes?
Stamenkovi?: Just like the answer above. Dynamics is still to be explored. (But this is a really good question ?).

Wikinews also asked Stamenkovi? how their research is linked to the recent discovery of possible large subglacial lake below the Martian South Pole found through radar mapping.

((WN)) Some news stories coupled your research with the subglacial lakes announcement earlier this year. Could the oxygen get through ice into layers of brines such as the possible subglacial lakes at a depth of 1.5 km?
Stamenkovi?: There are other ways to create oxygen. Radiolysis of water molecules into hydrogen and oxygen can liberate oxygen in the deep and that O2 could be dissolved in deep groundwater. The radiolytic power for this would come from radionuclides naturally contained in rocks, something we observe in diverse regions on Earth.
((WN)) And I’d also like to know about your experiment you want to send to Mars to help with the search for these oxygenated brines.
Stamenkovi?: We are now developing at “NASA/JPL-California Institute of Technology” a small tool, called TH2OR (Transmissive H2O Reconnaissance) that might one day fly with a yet-to-be-determined mission. It will use low frequency sounding techniques, capable of detecting groundwater at depths down to ideally a few km under the Martian surface, thanks to the high electric conductivity of only slightly salty water and Faraday’s law of induction. Most likely, such a small and affordable instrument could be placed stationary on the planet’s surface or be carried passively or actively on mobile surface assets; TH2OR might be also used in combination with existing orbiting assets to increase its sounding depth. Next to determining the depth of groundwater, we should also be able to estimate its salinity and indirectly its potential chemistry, which is critical information for astrobiology and ISRU (in situ resource utilization).
((WN)) Does your TH2OR use TDEM like the Mars 94 mission — and will it use natural ULF sources such as solar wind, diurnal variations in ionosphere heating and lightning?
Stamenkovi?: The physical principle it uses is the same and this has been used for groundwater detection on the Earth for many decades; it’s Faraday’s law of induction in media that are electrically conducting (as slightly saline water is).
Stamenkovi?: However, we will focus on creating our own signal as we do not know whether the EM fields needed for such measurements exist on Mars. However, we will also account for the possibility of already existing fields.

Considerations For Above Ground Swimming Pools Ct

byadmin

Swimming pools are a source of a lot of fun for you and your family members especially during the sweltering summer months. If you are a homeowner and have a large backyard, getting an above ground pool could be a great addition to your home as it takes little time to set up. However, although this is a convenient option when it comes to pools, you still need to ensure that the water as well as the structure of the pool as some regular maintenance. This will ensure that the pool is not only in place during the summer but also last for a significant number of years. Here are some considerations for an above ground swimming pools CT.

1. Caring for the pump and the filter. These are some of the most important component of swimming pools. The filter works to ensure that all debris is removed from the pools while the pump works to push water through the said filter. The pump is also essential in ensuring the water in swimming pools does not remain stagnant. Since they work in tandem, it is essential to ensure they are both in good condition.2. Get rid of dirt and algae. A common concern that owners of Swimming Pools CT have is the pool turning green. This typically occurs when algae has grown in the pool due to lack of proper circulation of the water. Ensuring that your pool is free of algae is of utmost importance. Not only does it look terrible, it could also pose a risk to the people that will be swimming in that pool. Presence of algae increases the chances of pools being infested with bacteria as they feed on the waste that the algae produce. To keep algae out of your pool, the walls and floors of Swimming Pools should be brushed regularly. In addition to this, the pool should be vacuumed at least once a week.3. Water sanitization. This is also important as it ensures that bacteria and other microorganisms are kept away frompools. Most of the popular sanitizers that you will come across will comprise of chlorine as well as bromine. However, you could also use sanitizers made up of chlorine alone. These pool sanitizers come in different forms such as tablets, sticks and more.

4. Monitor the chemistry of the pool. There are different chemical levels that should be checked on a regular basis. This will ensure that the chemistry of the swimming pool is optimum. Some of the different factors that should be tested include the pH levels of the swimming pool, the sanitizer levels of the pool, the stabilizer levels and more. It is essential that these levels are balanced as if they are too high or too low; the pool could start clouding or could turn its color.

Eradicating Ant Infestations

An ant infestation in a home or on a property can be a real nuisance. Ants, while not always harmful, can be destructive to property. They can cause damage by building mounds or disturbing pavement. Ants offer protection and care for other pests such as aphids, which may allow these pests to cause greater damage. The most common types of ants in Australia include species such as the: green-headed ant, meat ant, green tree ant, sugar ant, and jumper ant. Regardless of the ant species of severity of infestation, pest control Brisbane can help.

More information about pest inspection newcastle here

One of the most prevalent pests found in and around homes, ants can be an irritating nuisance. Ants can cause damage by building mounds or disturbing pavement; they also carry diseases and can spoil products. Some species can sting, bite, or cause severe allergic reactions. When ants are a problem, pest control may be the solution.

Ant Control Methods –

There are three basic strategies or methods that can be utilized to successfully treat ant problems. These three methods include: inspection, chemical treatments, and baiting. An inspection is the first step in controlling an ant problem because it is vital that the ant species be correctly identified. Each ant species has a propensity for certain foods and nesting conditions. A pest inspector can accurately determine which species is causing the problems thereby allowing for easier location of the ant’s nesting area.

Once the ant’s nesting area is located, chemical treatments or baiting can be used to eradicate the ant infestation. Both of these methods have advantages and disadvantages. Chemical treatments provide continuous protection because they can act as a barrier preventing future infestations. These liquid or dry powder treatments are safe for humans and pets. The effectiveness of this treatment will depend on the type of chemical used and the placement of the treatment.

Baiting works indirectly to annihilate the ant infestation. The bait used and the location of its placement will depend on the species of ant. Bait will be carried back to the nest, and the ants will feed on the bait. Over time, the ant colony will begin to die. However, bait will not eradicate the ant infestation immediately and may have to be replaced periodically.

What You Can Do –

Even though ants do play an important role in the natural food web, their presence in and around a property can be annoying and sometimes destructive. There are some preventative measures that property owners can take to proactively combat ant infestations. Reducing the food sources available for ants is important. Ensuring that rubbish is in properly sealed bags and cleaning up spills immediately are both crucial to preventing ant infestations. Another measure is maintaining the vegetation around the building. When vegetation is allowed to touch the building or its eaves or gutters, the potential for an ant infestation increases.

N.J. Simicich,

This keyboard sounds like a piano, within the limitations of its speakers. Better than certain real piano and much more unlikely to require an action tuneup.

Despite its advanced features plus the multitude of features, working it is logical.

It is really simple to operate. I plugged a thumb drive of songs in standard Midi format in the piano and it could play all of them as a midi player.

It had a more natural feel in comparison with some of the real pianos, in terms of consistency along with smoothness while still being weighted correctly.

Make Your Own Home Compost Bin

By Marcie Snyder

Many people think that the only way to make compost is to use a commercial bin, but nothing could be further from the truth. People in the past have built their own compost bin with much success. So if you want to give it a try, here are five easy cost-effective ways to build them.

Style 1: Extremely Simple And Easy

A circle of chicken wire, or a bottomless barrel with air holes in its sides, although simple, works fine. When you cannot add any more materials in the circle, just lift the wire away from the pile, set it up again nearby, and put the newer layers back in, leaving behind the finished compost.

Anything can be used for a compost bin. For instance, when I first settled in Oshawa, Ontario, I marvelled at the way my neighbor, an older Ukrainian lady, would create her compost. In the fall when she was cleaning up her garden for the winter, she would simply pile up all garden debris against a wire fence that had been set up between her land and the public park on the west side of her property. This section of her garden along the wire fence would be her “compost bin” during the winter months.

In the early spring as soon as the ground had thawed, she would spread this half- decomposed material all over her garden and have it plowed under. Then she would add mushroom compost bought from a mushroom grower. When it was time for seeding, everything had pretty well thoroughly decomposed. This lady had the nicest vegetables in the neighborhood.

(Please Note: If you decide to buy mushroom compost from a grower, first find out what the farmer uses to make his mushrooms grow. Things have changed a lot since the 1980’s. Today’s compost may be full of chemicals. So beware!)

Style 2: Pens

One of the simplest structures for a compost bin is a circle of snow fencing or wire mesh supported by posts or stakes. When it is time to aerate the pile, you unwrap and remove the fencing, set it up in a new location nearby, and fork the compost back into the pen.

[youtube]http://www.youtube.com/watch?v=gA6jZscrA4I[/youtube]

It’s true that this requires a little more space and some lifting effort, and it leaves the compost in full view. However, it is inexpensive, strong enough, and very easy to construct.

Style 3: Homemade Bin

Now let’s take a look at the third type of compost container for hot composting– the home-made bin. These are sturdier and more discreet than pens. They may require a little more skill to build but are still inexpensive.

The four sides can be made of almost anything: wire screen stretched on wooden frames or old pallets standing on end. Three walls are normally fixed permanently together but may be hinged, hooked or tied.

For example, you can build your compost bin with concrete walls and a movable front panel. Three of the four walls can be made of concrete blocks, stacked without mortar, and a fourth wall of removable boards.

Another idea is to stack up square bales of straw to create the three immovable walls of the bin. For a fourth wall you can always use a simple screen tacked onto a frame the size needed.

To turn the pile, you remove the front of the bin and fork the material out onto the ground. Then the pile is rebuilt in the bin.

The disadvantage is that extra ground space in front of the bin is needed for aerating the pile; however, its biggest advantage is that the compost does not need to be lifted over any wall when you need it or you wish to aerate the pile.

Another idea is to set a bin over a pit so that your compost pile gets the extra insulation. Although this encourages the presence of helpful earthworms, it does mean reaching down below ground level to turn the compost.

Style 4: Composting drum

You can also make your own rotating barrel composter. Simply take a large drum and punch aeration holes in it. If you wish, fins can be added inside the drum to lift and mix the compost materials. To finish it off, add a hinged loading door in the side so that you can add your waste.

One way to make your material inside the drum decompose faster is to roll the barrel on the ground to mix the contents. However, if you have welding skills, you can mount the barrel on a stand and add a crank attachment. Then all you need do is turn that crank every day or second day.

If bacteria is introduced with a good amount of garden soil and the barrel is turned every few days, compost can be made in a few weeks this way with little physical effort.

Style 5: A New Zealand Box

A New Zealand box is a bottomless wooden box with ventilation spaces between the wall boards, and an easily removable face to make it easier to remove the compost or to turn it. Since the compost rests directly on the ground, a lid is normally added to prevent nutrients leaking from the pile during heavy rains.

There are still some people who prefer the wooden type to the plastic ones you can buy at a store or sometimes from the municipality. For example, I know a lady who had three of them scattered around her yard. People love them because they make nice compost, are easy to make, and are light so easy to move.

A New Zealand box, or something similar, can be made at home by people with minimum skill. It can be moved to a new location fairly easily if required, and it keeps the compost neatly out of sight.

Variation of the New Zealand Box

A popular variation has two or three compartments in a row. The compost is turned from one box into another, and the empty box is then used to accumulate the material for a new batch of compost.

It is ideal for people who use kitchen and yard wastes as they accumulate, so they can’t save up enough materials to make a really big pile.

As you can see, compost bin ideas are limited only by your imagination. So why not give it a try?

8th case of mad cow disease found in Canada

Friday, August 25, 2006

An 8th case of mad cow disease was found in a cow in the province of Alberta. The Canadian Food Inspection Agency did a test and found BSE. The agency found no part of the beef cow’s carcass entered either the human or animal feed chains. The CFIA said that, “the cow could have likely lived another 6 months or so, but died of complications of mastitis”.

“The animal’s age is between eight and 10 years”, said the Canadian Food Inspection Agency.

The CFIA also traced 172 animals would likely ate feed out of that load.

“The cow’s exposure to BSE likely occurred before or during the introduction of new feed regulations in 1997 prohibiting use of cattle parts susceptible to the disease in certain animal feeds”, A release said yesterday.

An investigation is already underway to find the animal’s birth farm and potential sources of contaminated feed.

The United States has delayed lifting a ban on older cattle imports from Canada, pending investigation.

Poverty rises as food prices increase

Sunday, April 17, 2011

The World Bank, an organization that provides loans to developing countries, warned Thursday that rising food prices are driving millions of people deeper into poverty.

Robert Zoelick, World Bank president, said that food prices have risen 36% over the last year, pushing 44 million more people into poverty since last June. About 1.2 billion people are extremely poor.

He warned that a further increase of 10% in the cost of food would move an additional 10 million persons into extreme poverty, and there was no sign of a near term reversal in the inflation of food prices, which affects the developing world disproportionately.

“We have to put food first and protect the poor and vulnerable, who spend most of their money on food,” said Zoellick. “The general trend lines are ones where we are in a danger zone… because prices have already gone up and [food] stocks are relatively low,” he said.

The general trend lines are ones where we are in a danger zone.

The cost of the basic foods, such as wheat, maize and soy are all surging. Only rice has shown a slight decrease in price.

The steep rise in the cost of food is being driven by a combination of factors, including bad weather in food exporting areas such as Russia, Ukraine, North America and China, rising energy costs that increase the cost of producing and transporting food, and the incentives for farmers in many countries to produce crops for biofuels instead of for food.

“The linkage between food and fuel is much tighter than it was ten years ago,” said Zoellick.

Additionally, the change in diet of the growing middle class in developing countries means they consume more meat and pork products which take increased grain to produce and drives up the price of feed stocks.

The linkage between food and fuel is much tighter than it was ten years ago.

National food investment and export policies of some wealthier countries are affecting poorer nations. For example, China is acquiring large amounts of land in Africa to grow food for the needs of the Chinese; Saudi Arabia has given up wheat production to invest overseas for food, and a drought in Russia has led it to implement an export ban on wheat.

Zoellick spoke in Washington at the opening of the meetings of the World Bank and the International Monetary Fund (IMF). He hopes to discuss food policies with officials of the G-20 countries to develop a “code of conduct” on export bans and to encourage these countries to do more to increase food production and aid developing countries in managing agricultural problems.

On Saturday, the World Bank and the IMF issued “Global Monitoring Report 2011: Improving the Odds of Achieving the MDGs” which said the world was still on track toward reaching a key goal of reducing the number of the world’s people living in extreme poverty and hunger by half, to 883 million, by the target date of 2015. Most of the world’s progress is due to fast growth in India and China, while African countries are behind.

Global markets plunge

Friday, October 10, 2008

Stock markets across the world have fallen sharply with several seeing the biggest drop in their history.

Asian markets saw the biggest sell-off. The Nikkei dropped 9.62% to reach a 20 year low. Japan also saw a collapse of a mid-size insurance company, Yamato Life Insurance Company, which declared bankruptcy. The Hang Seng, which was one of the few markets that was positive yesterday, fell 7.19%. Australia dropped by 8.4% and South Korea saw a 9% fall.

In Europe, markets dropped at the open with the FTSE losing 11%. They have recovered only sightly with all European markets losing more than 5%. The European sell off was more about the Asian lows then any specific news. European banks and financial institutes saw the most selling. Also, oil related companies saw large drops as an result of an expected decrease in oil consumption.

The U.S. markets opened lower with the Dow Jones Industrial Average falling below 8,000, before recovering slightly. President George W. Bush made an address on the economy and said markets were being “driven by uncertainty and fear.”

Oil has seen losses of more than US$6 in trading with the current price of a barrel of oil less than $80. This is a year low for oil. News also came out that OPEC will hold an emergency meeting on November 18 to discuss the falling price of oil.

Charities, such as Cats Protection, today said that they have lost much of their funds in collapsing banks. Cats Protection had a total of £11.2 million saved in the now-collapsed Kaupthing bank.

The British National Council for Voluntary Organisations said that 60 of its 6,500 have lost money due to the collapse of banks.

The Dow Jones Industrial Average fell to its lowest level in five years at 8,579.19, falling 679 points in one day. This, at 7.3%, is the eleventh largest percentage fall in the history of the index. The growth then continued, with the index being up over 150 points on the start of the day at one point.

The index, did however, recover, and as of 19:30 UTC was up 17.68 points, or 0.21%, pushing the index up to almost 8600.

Peter Cardillo, chief market economist at Avalon Partners, commented on these massive falls. “What we’ve seen here was one big margin call that just kept feeding on itself, so the opposite could happen. But you need a catalyst,” he said. “I’m more convinced now than ever that this market has made a bottom. The capitulation came when we breached 8,000,” he continued. “It doesn’t mean we can’t go back and revisit that level.”

The UK’s FTSE 100 index fell dramatically to close below 4000, in the index’s worst week in history. This is despite the fact that just a few days ago the index was above 5000, and the index peaked above 5500 in September.The FTSE 100 index has fallen by 41% this year.

Barclays Wealth analyst Henk Potts commented on this massive fall. “We are drowning in a sea of red numbers,” he claimed. “Investors are concerned about the exacerbation of the credit crunch and the gloomy forecasts for economic growth. The reality is that most investors have been spooked by the sheer pressure that the credit crunch is putting on the global economy.”

The Japanese Nikkei 225 has recorded it’s third biggest drop in history with a massive sell-off in the exchange that has resulted in USD 250 billion being knocked of the index’s value.

Toyota, which is the second largest carmaker in the world, fell by the largest amount in 21 years, while Elpida Memory, the world’s largest manufacturer of computer memory, dropped in value to a record low.

Masafumi Oshiden, a fund manager in Toyota commented on the drop.”It’s capitulation,” he said. “There are lots of forced sellers. If you’re a fund that’s going bust you need to close out all your positions.”

George W. Bush commented on the financial situation earlier today. “Over the past few days, we have witnessed a startling drop in the stock market — much of it driven by uncertainty and fear,” he said. “This has been a deeply unsettling period for the American people. Many of our citizens have serious concerns about their retirement accounts, their investments, and their economic well-being.”

Bush then continued by promoting the government’s plan’s to get through the crises. “Here’s what the American people need to know: that the United States government is acting; we will continue to act to resolve this crisis and restore stability to our markets. We are a prosperous nation with immense resources and a wide range of tools at our disposal. We’re using these tools aggressively.”

Gordon Brown, the UK Prime Minister, also spoke on the economy. “I think we quickly realised that we cannot solve the problems we have got as a result of the sub-prime market collapse simply by improving liquidity,” he said speaking in Birmingham to business leaders earlier today. “That would simply not be enough to deal with the bigger problem of rebuilding the banking system for the future and restoring trust is a fundamental element of that.”

Jim Flaherty, the Canadian minister for finance, also commented today on the recent incidents in the economy. “It is important to underline that Canada’s banks and other financial institutions are sound, well capitalized and less leveraged than their international peers,” he claimed. “Our mortgage system is sound. Canadian households have smaller mortgages relative both to the value of their homes and to their disposable incomes than in the U.S.”

“”However, it is becoming increasingly clear that the continuing disruption of global credit markets, which has been severe and protracted, is making it difficult for our financial institutions to raise long-term funding. This is beginning to affect the availability of mortgage loans and other types of credit in Canada,” he continued. “The Government has therefore decided to act to address the current scarcity of private sector lending to Canadian mortgage markets and lending markets overall. This is going to make loans and mortgages more available and more affordable for ordinary Canadians and businesses.”

    ACLU, EFF challenging US ‘secret’ court orders seeking Twitter data

    Thursday, April 7, 2011

    Late last month, the American Civil Liberties Union (ACLU) and Electronic Frontier Foundation (EFF) filed objections to the United States Government’s ‘secret’ attempts to obtain Twitter account information relating to WikiLeaks. The ACLU and EFF cite First and Fourth amendment issues as overriding reasons to overturn government attempts to keep their investigation secret; and, that with Birgitta Jonsdottir being an Icelandic Parliamentarian, the issue has serious international implications.

    The case, titled “In the Matter of the 2703(d) Order Relating to Twitter Accounts: Wikileaks, Rop_G, IOERROR; and BirgittaJ“, has been in the EFF’s sights since late last year when they became aware of the US government’s attempts to investigate WikiLeaks-related communications using the popular microblogging service.

    The key objective of this US government investigation is to obtain data for the prosecution of Bradley Manning, alleged to have supplied classified data to WikiLeaks. In addition to Manning’s Twitter account, and that of WikiLeaks (@wikileaks), the following three accounts are subject to the order: @ioerror, @birgittaj, and @rop_g. These, respectively, belong to Jacob Apelbaum, Birgitta Jonsdottir, and Rop Gonggrijp.

    Birgitta is not the only non-US citizen with their Twitter account targeted by the US Government; Gonggrijp, a Dutch ‘ex-hacker’-turned-security-expert, was one of the founders of XS4ALL – the first Internet Service Provider in the Netherlands available to the public. He has worked on a mobile phone that can encrypt conversations, and proven that electronic voting systems can readily be hacked.

    In early March, a Virginia magistrate judge ruled that the government could have the sought records, and neither the targeted users, or the public, could see documents submitted to justify data being passed to the government. The data sought is as follows:

    1. Personal contact information, including addresses
    2. Financial data, including credit card or bank account numbers
    3. Twitter account activity information, including the “date, time, length, and method of connections” plus the “source and destination Internet Protocol address(es)”
    4. Direct Message (DM) information, including the email addresses and IP addresses of everyone with whom the Parties have exchanged DMs

    The order demands disclosure of absolutely all such data from November 1, 2009 for the targeted accounts.

    The ACLU and EFF are not only challenging this, but demanding that all submissions made by the US government to justify the Twitter disclosure are made public, plus details of any other such cases which have been processed in secret.

    Bradley Manning, at the time a specialist from Maryland enlisted with the United States Army’s 2nd Brigade, 10th Mountain Division, was arrested in June last year in connection with the leaking of classified combat video to WikiLeaks.

    The leaked video footage, taken from a US helicopter gunship, showed the deaths of Reuters staff Saeed Chmagh and Namir Noor-Eldeen during a U.S. assault in Baghdad, Iraq. The wire agency unsuccessfully attempted to get the footage released via a Freedom of Information Act request in 2007.

    When WikiLeaks released the video footage it directly contradicted the official line taken by the U.S. Army asserting that the deaths of the two Reuters staff were “collateral damage” in an attack on Iraqi insurgents. The radio chatter associated with the AH-64 Apache video indicated the helicopter crews had mistakenly identified the journalists’ equipment as weaponry.

    The US government also claims Manning is linked to CableGate; the passing of around a quarter of a million classified diplomatic cables to WikiLeaks. Manning has been in detention since July last year; in December allegations of torture were made to the United Nations High Commissioner for Human Rights regarding the conditions under which he was and is being detained.

    Reports last month that he must now sleep naked and attend role call at the U.S. Marine facility in Quantico in the same state, raised further concern over his detention conditions. Philip J. Crowley, at-the-time a State Department spokesman, remarked on this whilst speaking at Massachusetts Institute of Technology; describing the current treatment of Manning as “ridiculous and counterproductive and stupid”, Crowley was, as a consequence, put in the position of having to tender his resignation to Secretary of State Hillary Clinton.

    Despite his native Australia finding, in December last year, that Assange’s WikiLeaks had not committed any criminal offences in their jurisdiction, the U.S. government has continued to make ongoing operations very difficult for the whistleblower website.

    The result of the Australian Federal Police investigation left the country’s Prime Minister, Julia Gillard, having to retract a statement that WikiLeaks had acted “illegally”; instead, she characterised the site’s actions as “grossly irresponsible”.

    Even with Australia finding no illegal activity on the part of WikiLeaks, and with founder Julian Assange facing extradition to Sweden, U.S. pressure sought to hobble WikiLeaks financially.

    Based on a State Department letter, online payments site PayPal suspended WikiLeaks account in December. Their action was swiftly followed by Visa Europe and Mastercard ceasing to handle payments for WikiLeaks.

    The online processing company, Datacell, threatened the two credit card giants with legal action over this. However, avenues of funding for the site were further curtailed when both Amazon.com and Swiss bank PostFinance joined the financial boycott of WikiLeaks.

    Assange continues, to this day, to argue that his extradition to Sweden for questioning on alleged sexual offences is being orchestrated by the U.S. in an effort to discredit him, and thus WikiLeaks.

    Wikinews consulted an IT and cryptography expert from the Belgian university which developed the current Advanced Encryption Standard; explaining modern communications, he stated: “Cryptography has developed to such a level that intercepting communications is no longer cost effective. That is, if any user uses the correct default settings, and makes sure that he/she is really connecting to Twitter it is highly unlikely that even the NSA can break the cryptography for a protocol such as SSL/TLS (used for https).”

    Qualifying this, he commented that “the vulnerable parts of the communication are the end points.” To make his point, he cited the following quote from Gene Spafford: “Using encryption on the Internet is the equivalent of arranging an armored car to deliver credit card information from someone living in a cardboard box to someone living on a park bench.

    Continuing, the Katholieke Universiteit Leuven (KUL) expert explained:

    In the first place, the weak point is Twitter itself; the US government can go and ask for the data; companies such as Twitter and Google will typically store quite some information on their users, including IP addresses (it is known that Google deletes the last byte of the IP address after a few weeks, but it is not too hard for a motivated opponent to find out what this byte was).
    In the second place, this is the computer of the user: by exploiting system weaknesses (with viruses, Trojan horses or backdoors in the operating system) a highly motivated opponent can enter your machine and record your keystrokes plus everything that is happening (e.g. the FBI is known to do this with the so-called Magic Lantern software). Such software is also commercially available, e.g. for a company to monitor its employees.
    It would also be possible for a higly motivated opponent to play “man-in-the-middle”; that means that instead of having a secure connection to Twitter.com, you have a secure connection to the attacker’s server, who impersonates Twitter’s and then relays your information to Twitter. This requires tricks such as spoofing DNS (this is getting harder with DNSsec), or misleading the user (e.g. the user clicks on a link and connects to tw!tter.com or Twitter.c0m, which look very similar in a URL window as Twitter.com). It is clear that the US government is capable of using these kind of tricks; e.g., a company has been linked to the US government that was recognized as legitimate signer in the major browsers, so it would not be too large for them to sign a legitimate certificate for such a spoofing webserver; this means that the probability that a user would detect a problem would be very low.
    As for traffic analysis (finding out who you are talking to rather than finding out what you are telling to whom), NSA and GCHQ are known to have access to lots of traffic (part of this is obtained via the UK-USA agreement). Even if one uses strong encryption, it is feasible for them to log the IP addresses and email addresses of all the parties you are connecting to. If necessary, they can even make routers re-route your traffic to their servers. In addition, the European Data Retention directive forces all operators to store such traffic data.
    Whether other companies would have complied with such requests: this is very hard to tell. I believe however that it is very plausible that companies such as Google, Skype or Facebook would comply with such requests if they came from a government.
    In summary: unless you go through great lengths to log through to several computers in multiple countries, you work in a clean virtual machine, you use private browser settings (don’t accept cookies, no plugins for Firefox, etc.) and use tools such as Tor, it is rather easy for any service provider to identify you.
    Finally: I prefer not to be quoted on any sentences in which I make statements on the capabilities or actions of any particular government.

    Wikinews also consulted French IT security researcher Stevens Le Blond on the issues surrounding the case, and the state-of-the-art in monitoring, and analysing, communications online. Le Blond, currently presenting a research paper on attacks on Tor to USENIX audiences in North America, responded via email:

    Were the US Government to obtain the sought data, it would seem reasonable the NSA would handle further investigation. How would you expect them to exploit the data and expand on what they receive from Twitter?

    • Le Blond: My understanding is that the DOJ is requesting the following information: 1) Connection records and session times 2) IP addresses 3) e-mail addresses 4) banking info
    By requesting 1) and 2) for Birgitta and other people involved with WikiLeaks (WL) since 2009, one could derive 2 main [pieces of] information.
    First, he could tell the mobility of these people. Recent research in networking shows that you can map an IP address into a geographic location with a median error of 600 meters. So by looking at changes of IP addresses in time for a Twitter user, one could tell (or at least speculate about) where that person has been.
    Second, by correlating locations of different people involved with WL in time, one could possibly derive their interactions and maybe even their level of involvement with WL. Whether it is possible to derive this information from 1) and 2) depends on how this people use Twitter. For example, do they log on Twitter often enough, long enough, and from enough places?
    My research indicates that this is the case for other Internet services but I cannot tell whether it is the case for Twitter.
    Note that even though IP logging, as done by Twitter, is similar to the logging done by GSM [mobile phone] operators, the major difference seems to be that Twitter is subject to US regulation, no matter the citizenship of its users. I find this rather disturbing.
    Using 3), one could search for Birgitta on other Internet services, such as social networks, to find more information on her (e.g., hidden accounts). Recent research on privacy shows that people tend to use the same e-mail address to register an account on different social networks (even when they don’t want these accounts to be linked together). Obviously, one could then issue subpoenas for these accounts as well.
    I do not have the expertise to comment on what could be done with 4).
    ((WN)) As I believe Jonsdottir to be involved in the Icelandic Modern Media Initiative (IMMI), what are the wider implications beyond the “WikiLeaks witchhunt”?
    • Le Blond: Personal data can be used to discredit, especially if the data is not public.

    Having been alerted to the ongoing case through a joint press release by the ACLU and EFF, Wikinews sought clarification on the primary issues which the two non-profits saw as particularly important in challenging the U.S. Government over the ‘secret’ court orders. Rebecca Jeschke, Media Relations Director for the EFF, explained in more detail the points crucial to them, responding to a few questions from Wikinews on the case:

    ((WN)) As a worse-case, what precedents would be considered if this went to the Supreme Court?
    • Rebecca Jeschke: It’s extremely hard to know at this stage if this would go to the Supreme Court, and if it did, what would be at issue. However, some of the interesting questions about this case center on the rights of people around the world when they use US Internet services. This case questions the limits of US law enforcement, which may turn out to be very different from the limits in other countries.
    ((WN)) Since this is clearly a politicised attack on free speech with most chilling potential repercussions for the press, whistleblowers, and by-and-large anyone the relevant U.S. Government departments objects to the actions of, what action do you believe should be taken to protect free speech rights?
    • Jeschke: We believe that, except in very rare circumstances, the government should not be permitted to obtain information about individuals’ private Internet communications in secret. We also believe that Internet companies should, whenever possible, take steps to ensure their customers are notified about requests for information and have the opportunity to respond.
    ((WN)) Twitter via the web, in my experience, tends to use https:// connections. Are you aware of any possibility of the government cracking such connections? (I’m not up to date on the crypto arms race).
    • Jeschke: You don’t need to crack https, per se, to compromise its security. See this piece about fraudulent https certificates:
    Iranian hackers obtain fraudulent httpsEFF website.
    ((WN)) And, do you believe that far, far more websites should – by default – employ https:// connections to protect people’s privacy?
    • Jeschke: We absolutely think that more websites should employ https! Here is a guide for site operators: (See external links, Ed.)

    Finally, Wikinews approached the Icelandic politician, and WikiLeaks supporter, who has made this specific case a landmark in how the U.S. Government handles dealings with – supposedly – friendly governments and their elected representatives. A number of questions were posed, seeking the Icelandic Parliamentarian’s views:

    ((WN)) How did you feel when you were notified the US Government wanted your Twitter account, and message, details? Were you shocked?
    • Birgitta Jonsdottir: I felt angry but not shocked. I was expecting something like this to happen because of my involvement with WikiLeaks. My first reaction was to tweet about it.
    ((WN)) What do you believe is their reasoning in selecting you as a ‘target’?
    • Jonsdottir: It is quite clear to me that USA authorities are after Julian Assange and will use any means possible to get even with him. I think I am simply a pawn in a much larger context. I did of course both act as a spokesperson for WikiLeaks in relation to the Apache video and briefly for WikiLeaks, and I put my name to the video as a co-producer. I have not participated in any illegal activity and thus being a target doesn’t make me lose any sleep.
    ((WN)) Are you concerned that, as a Member of Parliament involved in the Icelandic Modern Media Initiative (IMMI), the US attempt to obtain your Twitter data is interfering with planned Icelandic government policy?
    • Jonsdottir: No
    ((WN)) In an earlier New York Times (NYT) article, you’re indicating there is nothing they can obtain about you that bothers you; but, how do you react to them wanting to know everyone you talk to?
    • Jonsdottir: It bothers me and according to top computer scientists the government should be required to obtain a search warrant to get our IP addresses from Twitter. I am, though, happy I am among the people DOJ is casting their nets around because of my parliamentary immunity; I have a greater protection then many other users and can use that immunity to raise the issue of lack of rights for those that use social media.
    HAVE YOUR SAY
    Do you believe the U.S. government should have the right to access data on foreign nationals using services such as Twitter?
    Add or view comments
    ((WN)) The same NYT article describes you as a WikiLeaks supporter; is this still the case? What attracts you to their ‘radical transparency’?
    • Jonsdottir: I support the concept of WikiLeaks. While we don’t have a culture of protection for sources and whistleblowers we need sites like WikiLeaks. Plus, I think it is important to give WikiLeaks credit for raising awareness about in how bad shape freedom of information and expression is in our world and it is eroding at an alarming rate because of the fact that legal firms for corporations and corrupt politicians have understood the borderless nature of the legalities of the information flow online – we who feel it is important that people have access to information that should remain in the public domain need to step up our fight for those rights. WikiLeaks has played an important role in that context.I don’t support radical transparency – I understand that some things need to remain secret. It is the process of making things secret that needs to be both more transparent and in better consensus with nations.
    ((WN)) How do you think the Icelandic government would have reacted if it were tens of thousands of their diplomatic communications being leaked?
    • Jonsdottir: I am not sure – A lot of our dirty laundry has been aired via the USA cables – our diplomatic communications with USA were leaked in those cables, so far they have not stirred much debate nor shock. It is unlikely for tens of thousands of cables to leak from Iceland since we dont have the same influence or size as the USA, nor do we have a military.
    ((WN)) Your ambassador in the US has spoken to the Obama administration. Can you discuss any feedback from that? Do you have your party’s, and government’s, backing in challenging the ordered Twitter data release?
    • Jonsdottir: I have not had any feedback from that meeting, I did however receive a message from the DOJ via the USA ambassador in Iceland. The message stated three things: 1. I am free to travel to the USA. 2. If I would do so, I would not be a subject of involuntary interrogation. 3. I am not under criminal investigation. If this is indeed the reality I wonder why they are insisting on getting my personal details from Twitter. I want to stress that I understand the reasoning of trying to get to Assange through me, but I find it unacceptable since there is no foundation for criminal investigation against him. If WikiLeaks goes down, all the other media partners should go down at the same time. They all served similar roles. The way I see it is that WikiLeaks acted as the senior editor of material leaked to them. They could not by any means be considered a source. The source is the person that leaks the material to WikiLeaks. I am not sure if the media in our world understands how much is at stake for already shaky industry if WikiLeaks will carry on carrying the brunt of the attacks. I think it would be powerful if all the medias that have had access to WikiLeaks material would band together for their defence.
    ((WN)) Wikinews consulted a Belgian IT security expert who said it was most likely companies such as Facebook, Microsoft, and Google, would have complied with similar court orders *without advising the ‘targets*’. Does that disturb you?
    • Jonsdottir: This does disturb me for various reasons. The most obvious is that my emails are hosted at google/gmail and my search profile. I dont have anything to hide but it is important to note that many of the people that interact with me as a MP via both facebook and my various email accounts don’t always realize that there is no protection for them if they do so via those channels. I often get sensitive personal letters sent to me at facebook and gmail. In general most people are not aware of how little rights they have as users of social media. It is those of uttermost importance that those sites will create the legal disclaimers and agreements that state the most obvious rights we lose when we sign up to their services.
    This exclusive interview features first-hand journalism by a Wikinews reporter. See the collaboration page for more details.
    ((WN)) Has there been any backlash within Iceland against US-based internet services in light of this? Do you expect such, or any increase in anti-American sentiments?
    • Jonsdottir: No, none what so ever. I dont think there is much anti-American sentiments in Iceland and I dont think this case will increase it. However I think it is important for everyone who does not live in the USA and uses social services to note that according to the ruling in my case, they dont have any protection of the 1st and 4th amendment, that only apply to USA citizens. Perhaps the legalities in relation to the borderless reality we live in online need to be upgraded in order for people to feel safe with using social media if it is hosted in the USA. Market tends to bend to simple rules.
    ((WN)) Does this make you more, or less, determined to see the IMMI succeed?
    • Jonsdottir: More. People have to realize that if we dont have freedom of information online we won’t have it offline. We have to wake up to the fact that our rights to access information that should be in the public domain is eroding while at the same time our rights as citizens online have now been undermined and we are only seen as consumers with consumers rights and in some cases our rights are less than of a product. This development needs to change and change fast before it is too late.

    The U.S. Government continues to have issues internationally as a result of material passed to WikiLeaks, and subsequently published.

    Within the past week, Ecuador has effectively declared the U.S. ambassador Heather Hodges persona-non-grata over corruption allegations brought to light in leaked cables. Asking the veteran diplomat to leave “as soon as possible”, the country may become the third in South America with no ambassadorial presence. Both Venezuela and Bolivia have no resident U.S. ambassador due to the two left-wing administrations believing the ejected diplomats were working with the opposition.

    The U.S. State Department has cautioned Ecuador that a failure to speedily normalise diplomatic relations may jeapordise ongoing trade talks.

    The United Kingdom is expected to press the Obama administration over the continuing detention of 23-year-old Manning, who also holds UK citizenship. British lawmakers are to discuss his ongoing detention conditions before again approaching the U.S. with their concerns that his solitary confinement, and treatment therein, is not acceptable.

    The 22 charges brought against Manning are currently on hold whilst his fitness to stand trial is assessed.

    Woman returns home with Christmas turkey, a month after setting out

    Tuesday, January 19, 2010

    A Scottish woman who set out before Christmas to purchase a turkey finally made it home on Monday, after being cut off by snow for a month. Kay Ure left the Lighthouse Keeper’s cottage on Cape Wrath, at the very northwest tip of Great Britain, in December. She was heading to Inverness on a shopping trip.

    However on her return journey heavy snow and ice prevented her husband, John, from travelling the last 11 miles to pick her up. She was forced to wait a month in a friend’s caravan, before the weather improved and the couple could finally be reunited.

    They were separated not just for Christmas and New Year, but also for Mr Ure’s 58th birthday. With no fresh supplies, he was reduced to celebrating with a tin of baked beans. He also ran out of coal, and had to feed the couple’s six springer spaniels on emergency army rations.

    “It’s the first time we’ve been separated”, said Mr Ure in December. “We’ve been snowed in here for three weeks before, so we are well used to it and it’s quite nice to get a bit of peace and quiet.”
