Nasa Scientists Levitate Mice With Magnet

Scientists have previously managed to levitate frogs and grasshoppers

From The Telegraph:

Nasa-backed scientists have successfully levitated mice, as part of research into the conditions endured by astronauts in space.

The mice were made to float using a superconducting magnet that produces a field strong enough to rival the pull of gravity.

After initial tests on baby mice left them frantically spinning in the air, the scientists decided to sedate the rodents to make their weightless ordeals less disturbing.

Describing the first test on a three-week-old baby mouse, researcher Yuanming Liu of the Jet Propulsion Laboratory in Pasadena, California, said: "It actually kicked around and started to spin.

New Malaria 'Poses Human Threat'

From The BBC:

An emerging new form of malaria poses a deadly threat to humans, research has shown.

It had been thought the parasite Plasmodium knowlesi infected only monkeys.

But it has recently been found to be widespread in humans in Malaysia, and the latest study confirms that it can kill if not treated quickly.

The work, by an international team, appears in the journal Clinical Infectious Diseases.

Bacteria Used To Make Radioactive Metals Inert

Judy Wall, a professor of biochemistry at the University of Missouri, is working with bacteria that convert toxic radioactive metal to inert substances.

From Science Daily:

ScienceDaily (Sep. 9, 2009) — The Lost Orphan Mine below the Grand Canyon hasn't produced uranium since the 1960s, but radioactive residue still contaminates the area. Cleaning the region takes an expensive process that is only done in extreme cases, but Judy Wall, a biochemistry professor at the University of Missouri College of Agriculture, Food and Natural Resources, is researching the use of sulfate-reducing bacteria to convert toxic radioactive metal to inert substances, a much more economical solution.

Infection Could Hasten Alzheimer's Memory Loss

From Live Science:

Catching a cold or any other infection could cause more memory loss in people with Alzheimer's disease, a new study suggests.

Alzheimer's is a form of dementia generally diagnosed in some people over 65. While it can result in everything from mood swings to language breakdown and loss of bodily functions, the most familiar hallmark of the disease is memory loss.

From New Scientist:

A robot controlled by human brain cells could soon be trundling around a British lab, New Scientist has learned.

Kevin Warwick and Ben Whalley at the University of Reading, UK, have already used rat brain cells to control a simple wheeled robotMovie Camera.

Some 300,000 rat neurons grown in a nutrient broth and producing spikes of electrical activity were connected to the output of the robot's distance sensors. The neurons proved capable of steering the robot around a small enclosure (see videoMovie Camera).

Panel Urges NASA to Reset Priorities

Astronaut Nicole Stott works on the International Space Station last week. Reuters

From The Wall Street Journal:

A blue-ribbon panel is recommending that NASA shelve its goal of rapidly returning to the moon and instead focus on nurturing a robust commercial space industry that can handle short-term objectives of the nation's space program, such as ferrying cargo and crew to the international space station.

The panel, called the Review of U.S. Human Space Flight Plans Committee, headed by former Lockheed Martin Corp. Chairman Norman Augustine, was convened by the Obama administration earlier this year to provide an independent assessment of the priorities of the National Aeronautics and Space Administration. It presented its findings to the White House Tuesday.

China Plans World's Largest Solar Power Plant

First Solar: Here the company installs a 2 megawatt solar plant in California. Up next, one that's one thousand times the wattage, in China. First Solar

From Popular Science:

First Solar just signed an agreement with China to build the biggest solar power plant yet, according to a statement released today by the company. The 2-gigawatt plant in the Mongolian desert will generate enough electricity to power three million homes.

That's a heck of a lot of cadmium telluride, the semiconductor they use for their thin film cells.

The largest solar plant currently in operation is a mere 60-megawatt plant in Spain, according to pvresources.com.

Buzz Aldrin to NASA: U.S. Space Policy Is on the Wrong Track

Platon photographed Buzz Aldrin for PM in Los Angeles, May 2009. “It’s mankind’s destiny to walk on another planet,” Aldrin says. “We can achieve it, but we’ve got to have the right plan.” (Photograph by Platon)

From Popular Mechanics:

Apollo 11 astronaut Buzz Aldrin has a problem with NASA’s current manned space plan: Namely, the five-year gap between the shuttle’s scheduled retirement next year and the debut of the Ares I rocket and the Orion spacecraft, which will take us no further than the moon—a place we’ve already been. Aldrin thinks NASA can do better. His plan is to scrap Ares I, stretch out the remaining six shuttle flights and fast-track the Orion to fly on a Delta IV or Atlas V. Then, set our sites on colonizing Mars. Here, Buzz challenges NASA to take on his bolder mission.

After Repairs, New Space Images From Hubble

The Hubble's new Wide Field Camera 3 peered into one of the more crowded places in the universe in this view of a small region inside the globular cluster Omega Centauri, which has nearly 10 million stars. NASA, ESA, and the Hubble SM4 ERO Team

From New York Times:

The cosmic postcards are back.

Astronomers on Wednesday unveiled new pictures and observations from the Hubble Space Telescope. With the exception of a picture last month of the bruise on Jupiter caused by a comet, they were the first data obtained with the telescope since a crew spent 13 days in orbit last May replacing, refurbishing and rebuilding its vital components.

“This is truly Hubble’s new beginning,” Edward Weiler, the associate administrator for science at the National Aeronautics and Space Administration, said at a news conference in Washington.

Houseplants Make Air Healthier

From Live Science:

Houseplants can neutralize harmful ozone, making indoor air cleaner, according to a new study.

Ozone, which is the main component of smog, forms when high-energy light, such as the ultraviolet light from the sun, breaks oxygen bonds, ultimately resulting in O3, three atoms of oxygen joining together. When formed higher up in the atmosphere, the ozone layer protects us from harmful UV rays. Ground-level ozone is not so pleasant.

Ancient 'Smell Of Death' Revealed

Dying stinks, even for woodlice

From The BBC:

When animals die, their corpses exude a particular "stench of death" which repels their living relatives, scientists have discovered.

Corpses of animals as distantly related as insects and crustaceans all produce the same stench, caused by a blend of simple fatty acids.

The smell helps living animals avoid others that have succumbed to disease or places where predators lurk.

This 'death recognition system' likely evolved over 400 million years ago.

The discovery was made by a team of researchers based at McMaster University, near Hamilton, Ontario, Canada, and is published in the journal Evolutionary Biology.

A Skull That Rewrites The History Of Man

One of the skulls discovered in Georgia, which are believed to date back 1.8 million years

From The Independent:

It has long been agreed that Africa was the sole cradle of human evolution. Then these bones were found in Georgia...

The conventional view of human evolution and how early man colonised the world has been thrown into doubt by a series of stunning palaeontological discoveries suggesting that Africa was not the sole cradle of humankind. Scientists have found a handful of ancient human skulls at an archaeological site two hours from the Georgian capital, Tbilisi, that suggest a Eurasian chapter in the long evolutionary story of man.
