In an analysis published on Friday in Science, scientists announced data collected from the Curiosity Rover show that Mars’s Gale Crater was once a chemically stratified lake, meaning the aquatic environment differed markedly between deep and shallow water. According to the report, “all of the physical, chemical, and energetic conditions necessary to establish a habitable environment were present on Mars between ~3.8 billion and 3.1 billion years ago.”

Analysis shows the chemical index of alteration fluctuated over time in a way that suggested the lake varied between hot, wet periods and colder, drier periods. The shallow water would have been rich in oxidants brought in from the atmosphere and groundwater, and the deeper water would have been oxidant poor. Phosphates, carbon, nitrogen, iron and sulfur, indicating chemistry suitable for life, have also been found there in a variety of compounds.

Lead author Joel Hurowitz of Stony Brook University explained, “These were very different, co-existing environments in the same lake[…] This type of oxidant stratification is a common feature of lakes on Earth, and now we’ve found it on Mars. The diversity of environments in this Martian lake would have provided multiple opportunities for different types of microbes to survive.”

The scientists also evaluated the fineness of the sediment, meaning the sizes of individual particles of dirt, dust and sand. Curiosity found larger grains near the edges of the lake where sediments from incoming rivers and streams would have fed it, and smaller ones in what would have been the deep lakebed, which is consistent with particles dropping out of the water as the current slows down. “We could tell something was going on,” Hurowitz said in a statement. “What was causing iron minerals to be one flavor in one part of the lake and another flavor in another part of the lake? We had an ‘Aha!’ moment when we realized that the mineral information and the bedding-thickness information mapped perfectly onto each other in a way you would expect from a stratified lake with a chemical boundary between shallow water and deeper water.”

A fire on Saturday destroyed the main hall of the Egyptian National Theatre in Cairo. Six people have been injured including three firefighters. No one was in the theatre at the time as it was closed for the weekend.

Egyptian state culture minister Faruq Hosni, said “The fire broke out in the main hall of the theatre. It was probably caused by an electrical short circuit.”

Ataba Square was filled with thick white smoke just after sunset as a total of 22 fire engines responded. Egyptian riot police were also deployed to keep crowds of people back while the firefighters attempted to extinguish the blaze.

A civil defence officer described the fire as being almost contained, following a brief burst of high winds which blew the flames towards neighbouring shops and other buildings. The three firefighters were admitted to hospital suffering from the effects of smoke inhalation.

Brig. Gen. Nasr Zakaria, a senior officer of the Civil Defence Service, later confirmed Minister Hosni’s earlier statement, telling MENA (Middle East News Agency) that an electrical short had indeed caused the fire, by triggering an explosion in the theatres air conditioning system.

On Friday, the Los Angeles Police Department arrested and charged a woman with murder, after she reportedly stabbed her ten-year-old daughter to death at the Air Force base Fort MacArthur residential facility in San Pedro, California. The girl’s father is a former member of the Navy.

The 49-year-old mother, Bong Sook Chavez, allegedly slit her daughter’s wrists and neck. Chavez slit her own wrists after attacking her daughter. In a statement issued on Monday, investigators say Chavez likely stabbed her daughter while she was asleep in bed.

Deputy Chief Pat Gannon told the Los Angeles Times Chavez has a history of mental health problems. According to Gannon, “The father was able to get the weapon away from her.” The father awoke at around 2:30 a.m. local time to find Chavez attacking her daughter.

The daughter, Quesi Chavez, later died at the University of Southern California’s Medical Center as a result of her wounds. As of Monday, the mother remained in the hospital in stable condition, but was scheduled to appear in court yesterday.

A doctor who worked at Children’s Hospital of Pittsburgh, Pennsylvania will be charged with aggravated murder after her mother was found dead in the trunk of her car Wednesday, authorities in Ohio say. Dr. Malar Balasubramanian, 29, was found in Blue Ash, Ohio, a suburb approximately 15 miles north of Cincinnati lying on the ground beside the road in a T-shirt and underwear in an apparently heavily medicated state. She directed officers to her black Oldsmobile Intrigue which was 500 feet away. There, they found the body of Saroja Balasubramanian, 53, covered with blood-stained blankets. Police said that the body appeared to have been there for about a day.

Dr. Malar Balasubramanian, formerly of the Squirrel Hill neighborhood of Pittsburgh, worked at Children’s Hospital from June 2001 to June 2004, according to Melanie Finnigan, a hospital spokeswoman. She had recently returned from work in India.

Former Massachusetts Governor Mitt Romney formally announced his presidential candidacy yesterday outside of Detroit.

“I don’t believe Washington can be transformed from within by lifetime politicians, there’ve been too many deals, too many favors, too many entanglements — and too little real world experience managing, guiding, leading,” said Romney, who was a successful businessman before entering politics. Romney focused on his leadership experience outside of government.

Romney made the announcement at the Henry Ford Museum, something which the National Jewish Democratic Council heavily criticized saying that they were, “deeply troubled by Governor Romney’s choice . . . to kick (off) his presidential campaign on the former estate of a well-known and outspoken anti-Semite and xenophobe.” A spokesman for Romney said, “Governor Romney believes our country needs to put innovation at the forefront if we are to ensure a stronger, safer and more prosperous America, the Ford Museum embodies that bold, innovative spirit.”

Romney’s record as a moderate and his Latter-day Saint faith are expected to be his primary campaign challenges.

Romney, born in Detroit, the son of former Michigan Governor, Republican Presidential candidate, and automotive pioneer George Romney, attended Cranbrook School of Michigan and Harvard Business and Law Schools. Romney ran against senior Massachusetts senator and Kennedy family member, Ted Kennedy. Romney won 41% percent of the vote against Kennedy in the closest election in Kennedy’s entire tenure in the United States Senate. Romney was also CEO of the Salt Lake Organizing Committee which was in charge of planning the 2002 Winter Olympics from 1999 to 2002, he took charge after the 2002 Winter Olympic bid scandal. He also sat on the board of Massachusetts-based office supply giant, Staples, Inc.

Wednesday, March 29, 2006The Australian House of Representatives today acknowledged the impact of the recent devastating Cyclone Larry and the efforts of the support given to the residents and communities of north Queensland in order to restore normal life.

Phillip Ruddock (Liberal, Berowra) moved a motion expressing this after Question Time today, which included a description of the devastation wrought on the area, the response by the Australian Government and the Australian Defence Force, and thanked the efforts of people for their “willingness to roll up their sleeves and get on with the job of cleaning up and rebuilding their towns and centres.”

The Leader of the Opposition, Kim Beazley (Labor, Brand) supported the motion, and congratulated the move to put General Peter Cosgrove in charge of operations, stating that soldiers “know how to work through logistics issues…how to work around officialdom or blockages”, praised both local federal and state members of Parliament, and especially the Labor Queensland state premier, Peter Beattie.

Bob Katter (Independent, Kennedy) was more critical in his speech. Katter thanked Beattie for his immediate response, but also described his confrontation with him and said how first responses were “simply not working”, but also praised Beattie’s decision on Cosgrove. Katter also described how the incident was “the worst natural disaster inAustralian history” and how the banana industry in north Queensland was decimated. Katter went on to describe the financial problems of the people in the region, the “huge gap” between the cost of rebuilding and insurance payouts, also asking “Are we going to pay people virtually nothing to sit on their backsides to do nothing or are we going to pay them a decent wage and have them rebuilding our communities for us?”

The debate is set to continue in the Main Committee, as an opportunity for many more members of the House of Representatives to speak to the motion, without taking up further time in the Chamber.

A team of archaeologists excavating an Ancient Egyptian tomb have discovered golden jewelry in a recently-discovered lower chamber at the Valley of the Kings burial site in Luxor, Egypt.

Two golden rings and five golden earrings were found in the tomb of Djehuty, an 18th-dynasty official of Queen Hatshepsut, and were probably the property of Djehuty or his family.

The discovery was announced by Farouk Hosni, Egypt’s current Minister of Culture.

Djehuty was overseer of the treasury and overseer of works for the Queen. Hatshepsut reigned approximately 1479–1458 BCE. Djehuty was responsible for managing the huge amounts of precious goods brought in from Egypt’s military expedition to Punt in the Horn of Africa and the vast building projects of Hatshepsut which have made the female pharaoh one of the most-remembered of any from ancient Egypt.

Djehuty died after Hatshepsut did, sometime during the reign of Thutmosis III. Both Hatshepsut’s and Thutmosis’s names are recorded on the tomb. In a fashion typical of ancient Egyptian rivalries, Hatshepsut’s name was partly obscured on the monument over the tomb sometime after the queen’s death.

The team, led by José Manuel Galán of the National Research Center (Consejo Superior de Investigaciones Científicas, CSIC), in Madrid, Spain, had been excavating the tomb, designated TT11 and located in the necropolis of Dra’ Abu el-Naga’, since 2002. While much of Djehuty’s funerary equipment was lost to fire in antiquity, the lower chamber of his tomb was concealed at the end of a three-meter shaft and discovered at the end of 2008.

A superficial description of the tomb itself was recorded almost two hundred years ago by 19th-century French Egyptologist Jean-François Champollion, rubble blocking the entrance hindered excavation until the 21st century. In that time, emphasis in Egyptology has changed from the cataloging of treasures to the investigation of ancient culture, life and religion.

Since excavation began, Djehuty’s tomb has yielded a number of surprises. It was discovered that the tomb was re-used repeatedly up to and during the Greco-Roman period. There is an unusual face-on depiction of pharaoh Thutmosis III hunting ducks, and the mummy of a young, bejewelled, as-yet unidentified woman.

In 2007, 44 preserved bunches of flowers thought to be from Djehuty’s funeral were found in the site. In their 8th season of excavation, which ended on February 22, 2009, the team also found considerable evidence that below Djehuty’s tomb is a network of burial sites from the 11th dynasty, four thousand years old.

The lower chamber also displays passages from the Egyptian funerary text the Book of the Dead on its walls and a colorful mural of the goddess Nut, an embodiment of the heavens, on the ceiling. The names of Djehuty and his parents were also intact in the second chamber; the names were defaced in the previously-known first chamber of the tomb, which had also been looted.

According to a press release from Dr. Zahi Hawass, Secretary General of Egypt’s Supreme Council of Antiquities, Djehuty’s tomb is only the fifth known decorated burial chamber of the 18th dynasty. An additional unusual feature of the tomb is that its upper chamber is decorated in relief, rather than simply paint. When the excavation is completed, Dr Galán’s team plans to open the site to the public as the carved stoneworks will not be destroyed by tourists’ activities as paint would.

The identification of Djehuty is a complicated one, as a number of officials of the 18th dynasty bore the name, including a general and several governors. The name itself is an alternate transliteration of the name of the Egyptian god usually written in English as Thoth.
