Bacteria from Mars found inside ancient meteorite

Martian bacteria arrived on Earth on a meteorite which smashed into the Antarctic 13,000 years ago, Nasa scientists believe.

Their fossilised remains have been found in the rock, which was blasted out of Mars 16 million years ago as the solar system was forming.  The meteorite, called Allen Hills 84001, made headlines in 1996 after fossils were found in it. Scientists believed they were bacteria from Earth that contaminated the rock while it lay in the frozen wastes.  But a Nasa report now says there is strong evidence they originated on Mars, according to The Sun.

Dr Emily Baldwin, deputy editor of the UK’s Astronomy Now magazine, said: “Many scientists argued that what looked like fossils in the meteorite were really caused by the explosive event, such as an asteroid impact, that blasted the rock out of Mars in the first place.  “But the Nasa team is now saying they have proved that they could not have been produced by the blast itself.
“If the features turn out to have an extraterrestrial, biological origin and were not formed during the 13,000 years the meteorite spent lying on Earth, this will have profound implications for our understanding of how life evolved in the solar system.”
Prof Colin Pillinger, of the Open University, who was behind Britain’s ill-fated Beagle 2 probe to the planet that was lost on Christmas Day 2003, said: “This is good quality work and more compelling evidence to add to the mix. These guys have been plugging away at this for years. It is a very careful study by very reputable people.”  The Nasa study, led by Kathie Thomas-Keprta, found carbonate discs and tiny magnetite crystals inside the space rock. Scientists were able to use high resolution electron microscopes that were not available 13 years ago.  They concluded “unusual chemical and physical properties” in the meteorite were “intimately associated within and throughout these carbonate disks”. That, they said, was evidence of interaction with water on Mars more than 3.5 billion years ago.  Nasa is expected to announce the findings, from its Johnson Space Centre in Houston, Texas, later this week.

WASHINGTON (AP) — President Obama declared the swine flu outbreak a national emergency, giving his health chief the power to let hospitals move emergency rooms offsite to speed treatment and protect noninfected patients.

The declaration, signed Friday night and announced Saturday, comes with the disease more prevalent than ever in the country and production delays undercutting the government’s initial, optimistic estimates that as many as 120 million doses of the vaccine could be available by mid-October.

Health authorities say more than 1,000 people in the United States, including almost 100 children, have died from the strain of flu known as H1N1, and 46 states have widespread flu activity. So far only 11 million doses have gone out to health departments, doctor’s offices and other providers, according to the Centers for Disease Control and Prevention officials.

Administration officials said the declaration was a pre-emptive move designed to make decisions easier when they need to be made. Officials said the move was not in response to any single development.

Health and Human Services Secretary Kathleen Sebelius now has authority to bypass federal rules when opening alternative care sites, such as offsite hospital centers at schools or community centers if hospitals seek permission.

Some hospitals have opened drive-thrus and drive-up tent clinics to screen and treat swine flu patients. The idea is to keep infectious people out of regular emergency rooms and away from other sick patients.

Hospitals could modify patient rules — for example, requiring them to give less information during a hectic time — to quicken access to treatment, with government approval, under the declaration.

As the swine flu outbreak strikes the U.S. early and hard, health officials note a worrisome number of child deaths and warn that supplies of vaccine will remain scarce for at least the next couple of weeks.

Delays in producing the vaccine mean 28 million to 30 million doses, at most, will be divided around the country by the end of the month, not the 40 million-plus states had been expecting. The new count from the Centers for Disease Control and Prevention means anxiously awaited flu-shot clinics in some parts of the U.S. may have to be postponed.

It also delays efforts to blunt increasing infections. Overall, what CDC calls the 2009 H1N1 flu is causing widespread disease in 41 states, and about 6 percent of all doctor visits are for flu-like illness — levels not normally seen until much later in the fall.

Federal health officials said Friday 11 more children have died in the past week because of the virus.The Centers for Disease Control and Prevention says about half of the child deaths since September have been among teenagers. And overall for the country, deaths from pneumonia and flu-like illnesses have passed what CDC considers an epidemic level.
“These are very sobering statistics,” says the CDC’s Dr. Anne Schuchat.
This new strain is different from regular winter flu because it strikes the young far more than the old, and child deaths are drawing particular attention. Eighty-six children have died of swine flu in the U.S. since it burst on the scene last spring — 43 of those deaths reported in September and early October alone, said Schuchat.
