The Solar Impulse, an experimental solar-powered airplane, landed in Switzerland on Thursday after completing a successful 26-hour test flight. The flight was a proof-of-concept displaying that a solar-powered aircraft can accumulate enough power from the sun during the day to power it through the night. The team that designed and built the aircraft believes that, in theory, the plane could fly indefinitely, given that there is enough sunlight to power it.

The flight is the longest and highest flight by a piloted solar-powered aircraft, with an average altitude of about 28,000 feet, and an average speed of around 25 miles per hour. Pilot Andre Borschberg, a former fighter pilot in the Swiss air force, said “I’ve been a pilot for forty years now, but this flight has been the most incredible of my flying career. Just sitting there and watching the battery charge level rise and rise thanks to the sun. I have just flown more than 26 hours without using a drop of fuel and without causing any pollution.”

The plane can carry only one passenger, and contains 12,000 solar cells. However, the plane does have its setbacks; a blog on the project’s website reported after seventeen hours of flight that “Andre’s feeling great up there. His only complaints involve little things like a slightly sore back as well as a ten-hour period during which it was minus twenty degrees Celsius in the cockpit. That made his drinking water system freeze up and worst of all his iPod batteries die.”

The project’s intention is to show that emissions-free air travel is a feasible concept; however, the team does not believe that current propulsion methods will be replaced by alternatives in the near future.

Trusteer, a web security company, reports that a trojan horse virus called Zeus can steal online banking details from infected computers. The virus has infected one out of every 3,000 computers of the 5,500,000 million which the company monitors in the United States and the United Kingdom.

The trojan can infect users of Mozilla Firefox and Microsoft Internet Explorer on Microsoft Windows, and steals login information by recording keystrokes when the machine connects to certain websites, usually banks or other financial institutions. The stolen data is transmitted to a remote server and sold to cyber-criminals. “We expect this new version of Zeus to significantly increase fraud losses, since nearly 30% of Internet users bank online with Firefox and the infection is growing faster than we have ever seen before,” said Amit Klein, chief technology officer at Trusteer, to BBC.

The trojan has also affected Wikinews users, including Brian McNeil, who is the founder of Wikinewsie, a restricted-access wiki used to collaborate on sensitive news reports. McNeil reported on his userspace: “On Saturday [April] 17, a Windows-based PC in the house issued a cry for help, the Avira package running on the system had just detected a piece of malware; full scans indicated several known pieces of malware and numerous hidden files. Additional scans revealed that all but one of the USB memory sticks and portable hard drives in the house were infected with something. The Zeus botnet, as it turned out.” E-mail accounts for accredited reporters have also been affected.

The World Health Organisation (WHO), in a statement issued Tuesday, urged scientists to destroy samples of a deadly flu virus that could potentially cause a global pandemic.

Shipments of the influenza virus sent to Mexico and Lebanon are unaccounted for. The U.N. health organization said 10 countries receiving samples already destroyed them, while 5 more countries are in the process of doing so.

The virus, A/H2N2, was detected by a Canadian lab which contacted the Public Health Agency of Canada, who in turn warned the WHO and other national health agencies on March 26.

Meridian Bioscience sent routine testing kits infected with the virus to almost 5,000 laboratories, of which 3747 in 18 countries have so far been identified as having the virus, most of them in North America.

The virus is a variant of the H2N2 virus which caused the 1957 Asian Flu Pandemic, but which was displaced by the H3N2 variant. People born after 1959 are unlikely to be immune to the virus.

India is the latest of the countries where the One Laptop Per Child (OLPC) experiment has started. Children from the village of Khairat were given the opportunity to learn how to use the XO laptop. During the last year XO was distributed to children from Arahuay in Peru, Ban Samkha in Thailand, Cardal in Uruguay and Galadima in Nigeria. The OLPC team are, in their reports on the startup of the trials, delighted with how the laptop has improved access to information and ability to carry out educational activities. Thailand’s The Nation has praised the project, describing the children as “enthusiastic” and keen to attend school with their laptops.

Recent good news for the project sees Uruguay having ordered 100,000 of the machines which are to be given to children aged six to twelve. Should all go according to plan a further 300,000 machines will be purchased by 2009 to give one to every child in the country. As the first to order, Uruguay chose the OLPC XO laptop over its rival from Intel, the Classmate PC. In parallel with the delivery of the laptops network connectivity will be provided to schools involved in the project.

The remainder of this article is based on Carla G. Munroy’s Khairat Chronicle, which is available from the OLPC Wiki. Additional sources are listed at the end.

An acrobatic group known by the name of Spelbound has been declared as the winner of Britain’s Got Talent 2010, a televised variety talent show competition broadcast on ITV in the United Kingdom. As the winning act of the show, Spelbound have won £100,000 (US$144,580, €120,313, A$175,079) and a place at The Royal Variety Performance, an annual gala evening that is attended by senior members of the British Royal Family.

In no particular order, the top three acts were revealed to be two dancers known by their stage name of Twist and Pulse, gymnastic group Spelbound and Kieran Gaffney, whose act involves playing on the drum kit. After Kieran Gaffney was revealed to be in third place, Anthony McPartlin, who hosts Britain’s Got Talent with Declan Donnelly, said to Kieran: “Well done Kieran. Kieran, you’re a star, you came back, you got all the way to the final. I know you’ve loved this. You’ve loved this, haven’t you?” In response to this, Kieran Gaffney stated: “Thank you very much. Thank you, everyone for supporting me. Thank you.”

Shortly afterwards, on the episode that was broadcast live on ITV1 on Saturday, Anthony announced: “After tens of thousands of auditons, five semi-finals and an amazing final, this…this is it. One of you is about to walk away with £100,000 and a place at this year’s Royal Variety Performance. The winner of Britain’s Got Talent 2010 is…Spelbound!” Glen Murphy from Twist and Pulse commented about finishing in second place, stating: “Yeah, it’s amazing. I can’t even believe it. I can’t believe it at all.”

Alex Uttley, a 24-year-old member of Spelbound, commented on the gymnastic group’s victory, commenting: “Oh, my god. This is unbelieveable. We just want to say thank you to everyone out there. It just shows that all our hard work has paid off.” One of the coaches of Spelbound, named Neil Griffiths, stated about Spelbound: “Oh, they’ve worked so hard over the last few weeks. Um, since the semi-final, we…we really had to pull out the stops to try and up the game. They’ve not known they’ve worked in the gym from six in the morning till twelve…twelve o’clock of the night. I couldn’t have asked for more. Um, it’s a team of coaches. I don’t take all the credit myself. There’s, uh, two people up there that know who they are who’ve been fantastic.”

Spelbound consists of 24-year-old Alex Uttley, Nicholas Illingworth, aged 24, Adam Buckingham, aged 21, 20-year-old Adam McAssey, 19-year-old Douglas Fordyce, 18-year-old Edward Upcott, 18-year-old Leighanne Cowler, 17-year-old Katie Axten, 17-year-old Lauren Kemp, 15-year-old Jonathan Stranks, Abigail Ralph, aged 15, 13-year-old Hollianne Wood and Amy Mackenzie, aged 12. Bookmakers had previously predicted that Spelbound would be the most likely act to become the winner of the series.

The running order for the final started with Twist and Pulse. The second act to perform was Liam McNally, a 14-year-old singer. The running order subsequently continued with 40-year-old impressionist Paul Burling, singer Christopher Stone, aged 28, Tina & Chandi, a woman and dog dancing act, Connected, a five-piece singing group, Kieran Gaffney, aged 12, 22-year-old Tobias Mead, a dancer, 80-year-old singer Janey Cutler and Spelbound in that particular order.

Earlier on in the final, Britain’s Got Talent judge Amanda Holden has stated to Spelbound: “We are hosting the 2012 Olympics and I think ‘what a brilliant opening act’.” Fellow judge Piers Morgan also commented that “[t]he purpose of this show is to identify hidden great British talent. You are that act.” After Spelbound won in the final, another judge, named Simon Cowell, stated that “the right boys and girls won on the night” and that he could “only say on live TV that that was one of the most astonishing things I have ever seen. Seriously.”

An H-IIA rocket, carrying the SELENE lunar orbiter and several smaller satellites, was launched on Friday, September 14 from the Tanegashima Space Center in Japan.

The launch, conducted at 01:31 GMT by Mitsubishi Heavy Industries for the Japan Aerospace Exploration Agency (JAXA), begins the voyage of SELENE to the Moon, and Japanese space officials say that the mission has been going smoothly.

“The flight has been proceeding smoothly to this point. We haven’t had any reports of problems with any of the equipment,” said JAXA spokesman Seiji Toyama who also added that the probe is about to finish its first of two orbits around Earth.

SELENE will be placed in orbit 60 miles (100 kilometers) above the Moon‘s surface where two smaller probes will be released and then begin to orbit the Moon at both poles. Scientists are hoping that the data will shed more light on how the Moon was formed, and how it has evolved through time. They also hope to study the composition of dust samples from the surface and are planning on taking 3-D images of the Moon’s surface.

JAXA was forced to delay the launch by one day, with the launch originally scheduled to occur on September 13.

Australian researchers say they have scientifically proven that stress causes sickness. The Garvan Institute in Sydney has discovered that a hormone, known as neuropeptide Y, (NPY) is released into the body during times of stress. Their findings show the hormone can stop the immune system from functioning properly.

“Neuropeptide Y is one of those hormones that gets unregulated or released from neurones when stressful situations occur…it’s known for example that it regulates blood pressure and heart rates so your heart rate goes up but it hasn’t been known that it actually can affect immune cells as well,” said Professor Herbert Herzog, one of the researchers.

Herzog feels it is good to finally have proof of something people have suspected for so long.

“Now we have proven without doubt that there is a direct link and that stress can weaken the immune system and that makes you more vulnerable when you for example have a cold or flu and even in the more serious situations such as cancer can be enhanced in these situations,” said Herzog.

The Garvan Institute study centres on two key events that enable the human body to recognise foreign substances and control invaders. When our body encounters a pathogen (bacteria and viruses), the immune cells retain and interrogate suspects. Their activation is made possible by NPY. These cells then return to the lymph nodes, which are found all over the body, with information about the foreign invaders. The lymph nodes are where decisions about defence are made.

“Most of us expect to come down with a cold or other illness when we are under pressure, but until now we have mostly had circumstantial evidence for a link between the brain and the immune system,” said lead Garvan researcher, associate Professor Fabienne Mackay. “During periods of stress, nerves release a lot of NPY and it gets into the bloodstream, where it directly impacts on the cells in the immune system that look out for and destroy pathogens (bacteria and viruses) in the body.”

In the case of bacteria and viruses, TH1 cells are part of the attack team that is sent out on the ‘search and destroy’ mission. But when their job is done they need to be turned ‘off’ and the immune system reset. The same hormone, NPY, that activates the sentry cells now prompts the TH1 cells to slow down and die.

“Under normal conditions, circulating immune cells produce small amounts of NPY, which enables the immune cells on sentry duty and the TH1 immune cells to operate – it’s a yin and yang kind of situation. But too much NPY means that the TH1 attack is prevented despite the foreign invaders being identified – and this is what happens during stress,” added McKay.

The impact of stress on the body has been observed in athletes. Ph. D researcher at the University of Queensland, Luke Spence, together with the Australian Institute of Sport, studied elite and recreational athletes over five months.

They found elite athletes were more susceptible to respiratory diseases under stress.

“A lot of elite athletes put themselves through vast amounts of physical stress in their training, but also their emotional, psychological stress of feeling the pressure of Australia on their shoulders, wanting to compete and wanting to do their best,” said Spence.

It’s not just athletes who are prone to stress. Pressures at work and at home may cause emotional and mental stress that can be equally damaging. Almost a third of all work absenteeism in Australia is due to illness, costing employers over $10 billion a year.

“I think it has a huge impact for the work force and also for employers – if their employees are constantly stressed, constantly under pressure, they are more likely to get sick,” Spence said.

Further research could lead to the development of new drugs which may inhibit the action of the neuropeptide Y hormone.

Herzog warns people to minimise stress before it becomes a problem.

“Relaxation methods like yoga will help you to prevent that but there will still be people out there that are not responding to that and treatment by interfering with the system will be important,” he said. “There’s obviously some time until such a treatment will be available but this is something we will definitely work towards.”

The Garvan research will be published in the Journal of Experimental Medicine, Volume 202, No. 11.
