How 'Superswarms' Of Krill Gather


From The BBC:

When krill come together, they form some of the largest gatherings of life on the plant.

Now scientists have discovered just how these small marine crustaceans do it.

Huge 'superswarms' containing trillions of krill are formed by juveniles not adults, and these swarms are even denser than experts supposed.

That suggests that all krill in the Southern Ocean are more vulnerable to overfishing then previously thought, the scientists warn.

Krill are small shrimp-like crustaceans that gather in huge numbers.

Household Robots Do Not Protect Users' Security And Privacy, Researchers Say

From Science Daily:

Science Daily (Oct. 9, 2009) — People are increasingly using household robots for chores, communication, entertainment and companionship. But safety and privacy risks of information-gathering objects that move around our homes are not yet adequately addressed, according to a new University of Washington study.

It's not a question of evil robots, but of robots that can be misused.

"A lot of attention has been paid to robots becoming more intelligent and turning evil," said co-author Tadayoshi Kohno, a UW assistant professor of computer science and engineering. "But there is a much greater and more near-term risk, and that's bad people who can use robots to do bad things."

Universe To End Sooner Than Previously Thought

Find The Entropy In This Super Massive Black Hole via Jevin Studios

From Popular Science:

While Robert Frost famously said that he prefers the world to end in fire, physicists have long predicted the universe will end with an icy sputter known as "heat death." Heat death occurs when the universe finally uses up all its energy, with all motion stopping and all the atoms in creation grinding to a halt. And, based on new calculations from a team of Australian physicists, it looks like heat death is far closer than previously thought.

Look Into My Eyes: The Power Of Hypnosis



From New Scientist:

I AM about to have my left leg paralysed, my arm taken over by an alien force and, quite possibly, be made blind. I confess I'm a bit nervous. But also, strangely, I hope it all works.

These insults to my body will not be inflicted with a scalpel, but instead induced using hypnosis. The effects, if they occur, will only be temporary, my hypnotist, David Oakley, reassures me.

Nasa Team Scours Moon Crash Data

The "shepherding spacecraft" will analyse the impact debris

From The BBC:

Nasa scientists have been outlining their preliminary results after crashing two unmanned spacecraft into the Moon in a bid to detect water-ice.

A rocket stage slammed into the Moon's south pole at 1231 BST (0731 EDT).

Another craft followed just behind, looking for signs of water in debris kicked up by the first collision.

Instruments on the second spacecraft identified a flash from the initial impact as well as a crater, but the expected debris cloud was not evident.

Is China Beating The U.S. In Clean Tech?

Credit: Technology Review

From The Technology Review:

The president of NRDC points to a growing investment by China in energy technologies.

China could beat the United States in a race to deploy clean energy technology that can reduce greenhouse-gas emissions, said Frances Beinecke, leader of a leading environmental group, speaking this week at MIT.

"I just got back from China, where there is tremendous investment in the clean tech sector," said Beinecke, the president of the Natural Resources Defense Council (NRDC). "They have a national renewable energy standard, a national efficiency standard, and China will build more of everything--more coal, more nuclear, more renewables--and they'll invest in more efficiency than any other single country in the world."

From Science Daily:

ScienceDaily (Oct. 9, 2009) — You would have to go back at least 15 million years to find carbon dioxide levels on Earth as high as they are today, a UCLA scientist and colleagues report Oct. 8 in the online edition of the journal Science.

"The last time carbon dioxide levels were apparently as high as they are today — and were sustained at those levels — global temperatures were 5 to 10 degrees Fahrenheit higher than they are today, the sea level was approximately 75 to 120 feet higher than today, there was no permanent sea ice cap in the Arctic and very little ice on Antarctica and Greenland," said the paper's lead author, Aradhna Tripati, a UCLA assistant professor in the department of Earth and space sciences and the department of atmospheric and oceanic sciences.

In Test of Water on Moon, Craft Hits Bull’s-Eye -- New York Times

MOUNTAIN VIEW, Calif. — More than 230,000 miles from Earth, a NASA spacecraft hit a bull’s-eye on the Moon on Friday morning. Actually, two bull’s-eyes.

At 4:31 a.m. Pacific time (7:31 a.m. Eastern time), one piece of the Lunar Crater Observation and Sensing Satellite — LCROSS, for short — slammed into the bottom of a crater at 5,600 miles per hour, excavating about 350 metric tons of the moon and leaving behind a hole about 65 feet wide, 13 feet deep.

Trailing four minutes behind, instruments aboard the second piece analyzed the rising plume and sent its observations back to Earth before it also slammed into the same crater.
