Update: Rock Snot algae spreading - threatens New England waterways

It looks like a clump of soiled sheep's wool, a cottony green or white mass that's turning up on rocks and river bottoms, snarling waterways.

The aquatic algae didymo -- Didymosphenia geminata -- has infested rivers in New Zealand with gray floating growth but had never been seen in the Northeast before this summer when fishermen spotted it in the upper Connecticut and White rivers. Northeast states are on alert. They're warning anglers and boaters to scour their boats and clean their gear to prevent the algae's spread.

Pathocracy of Microworld: Microbial cheats orchestrate their own downfall

Cooperation is widespread in the natural world but so too are cheats - mutants that do not contribute to the collective good but simply reap the benefits of others' cooperative efforts. In evolutionary terms, cheats should indeed prosper, so how cooperation persists despite the threat of cheat takeover is a fundamental question. Recently, biologists at the Universities of Edinburgh and Oxford have found that in bacteria, cheats actually orchestrate their own downfall.

Observations Of Asteroid Itokawa Will Aid In Assessing Risks From Future Asteroids

The space-borne infrared observatory AKARI, observed asteroid Itokawa last month with its Infrared Camera. The data will be used to refine estimates of sizes of potentially hazardous asteroids in the future.

The asteroid Itokawa was observed by the Infrared Camera (IRC) onboard AKARI at 7 micrometres on 26 July 2007. The above image is a composite of three images from the data showing the motion of Itokawa over 12 minutes. The image covers an area of roughly 7.4 arcminutes x 7.4 arcminutes around the target. The Hayabusa spacecraft itself was too faint to be detected.

China searches for 8 kg of "missing" uranium

Eight kg (17 lb) of radioactive uranium has gone missing in China, delaying the verdict in a trial of four men charged with attempting to sell it on the black market, state media said on Friday.

A court in Guangzhou, capital of China's southern province of Guangdong, heard the four tried to sell the material between 2005 and January 2007, the China Daily said.

The men were arrested in January after a potential buyer in Hong Kong reported them to the authorities, the paper said.

However, despite having the four men in custody, police were unable to locate the uranium.

Fossil find pushes human-ape split back millions of years

Ten million-year-old fossils discovered in Ethiopia show that humans and apes probably split six or seven million years earlier than widely thought, according to landmark study released Wednesday.

The handful of teeth from the earliest direct ancestors of modern gorillas ever found -- one canine and eight molars -- also leave virtually no doubt, the study's authors and experts said, that both humans and modern apes did indeed originate from Africa.

Astronomers excited about nothing

Astronomers have stumbled upon a tremendous hole in the universe. That's got them scratching their heads about what's just not there.

The cosmic blank spot has no stray stars, no galaxies, no sucking black holes, not even mysterious dark matter. It is 1 billion light years across of nothing. That's an expanse of nearly 10 billion trillion kilometres of emptiness, a University of Minnesota team announced Thursday.

Martian soil may contain life: study

The soil on Mars may contain microbial life, according to a new interpretation of data first collected more than 30 years ago.

The search for life on Mars appeared to hit a dead end in 1976 when Viking landers touched down on the red planet and failed to detect biological activity.

Scientists Study Out-Of-Body Experiences

WASHINGTON - The stories seem strange but riveting. A heart attack victim recalls floating in the air, watching paramedics revive him. A surgical patient remembers hovering, watching the doctors operate. Such widely reported out-of-body experiences have long been the territory of theology, philosophy and scary movies. Now scientists have turned their attention to the topic.

Comment: The experiment seems stranger then an "out-of-body experience".

Seahenge saga comes full circle in UK

The story of Seahenge has turned full circle, as the ancient timbers are returned to Norfolk. But as experts prepare them to go on display at King's Lynn Museum, CHRIS BISHOP finds an enigma that remains unsolved.

Nearly 10 years after its controversial excavation, the mystery remains. While the upturned oak tree and its ring of timbers have taught us a few things we didn't know about our ancestors, we still don't know why they built it.
