Canadian geologists say they can shed light on how a vast lake, trapped under the ice sheet that once smothered much of North America, drained into the sea, an event that cooled Earth's climate for hundreds of years.
During the last ice age, the Laurentide Ice Sheet once covered most of Canada and parts of the northern United States with a frozen crust that in some places was three kilometres (two miles) thick.

The Tujia have been known as an ethnic minority with its own spoken language but without a written language. Yet a succession of ancient books in the same written language have been found in the Youyang Tujia habitation straddling the borders of Hunan, Hubei, Guizhou Province, and Chongqing City. For the past two years none have been able to read the ancient books.

Albert Einstein and Isaac Newton displayed symptoms of psychiatric disorders that may have been a key to their genius, a Dublin psychiatrist said.
Michael Fitzgerald, Professor of Psychiatry at Trinity College, Dublin, said characteristics linked to autism spectrum disorders such as Asperger's syndrome are the same as those associated with creative genius, The Daily Telegraph said.
Fitzgerald, author of the book, "Genius Genes: How Asperger Talents Changed the World," said Enoch Powell and Charles de Gaulle both appear to have had Asperger's syndrome.

NASA has selected a proposal by an MIT-led team to develop plans for an array of radio telescopes on the far side of the moon that would probe the earliest formation of the basic structures of the universe. The agency announced the selection and 18 others related to future observatories on Friday, Feb.15.

Scientists at the University of York have characterised an important new step in the mechanism used by bacteria to evade our immune system.
It is an 'invisibility cloak' which means that bacteria like Haemophilus influenzae, a common cause of ear infections in children, can move about the body without the risk of being attacked by the immune system.
A multidisciplinary research team from the Departments of Biology and Chemistry at York have been studying how bacteria capture the molecule used to make the 'cloak', called sialic acid.

When scientists around the world think of dung, they think of Jim Mead.
Mead, a researcher at Northern Arizona University, is one of the world's foremost authorities on animal dung, and he's got the poop to prove it.
"You have got to laugh at this bizarre resource," says Mead, director of NAU's Laboratory of Quaternary Paleontology. "Although I don't think anyone is keeping track, I suspect we have the largest comparative animal dung collection in the world. If someone needs to identify dung, they send it to me."
The lab, part of the university's Center for Environmental Sciences and Education, has row after row of cabinets with thousands of dung pieces used by scientists to get accurate data on an array of topics, including the environmental changes that took place on the Colorado Plateau during the last 100,000 years.

Now it is possible to see a movie of an electron. The movie shows how an electron rides on a light wave after just having been pulled away from an atom. This is the first time an electron has ever been filmed, and the results are presented in the latest issue of Physical Review Letters.
Previously it has been impossible to photograph electrons since their extremely high velocities have produced blurry pictures. In order to capture these rapid events, extremely short flashes of light are necessary, but such flashes were not previously available. With the use of a newly developed technology for generating short pulses from intense laser light, so-called attosecond pulses, scientists at the Lund University Faculty of Engineering in Sweden have managed to capture the electron motion for the first time.

Our planet faces a fiery doom inside the sun unless future generations work out how to change its orbit.
The remnants of at least ten pyramids have been discovered on the coast of Peru, marking what could be a vast ceremonial site of an ancient, little-known culture, archaeologists say.
