Looks Matter More In A City


From Live Science:

For women, looks may matter more if they live in the city than in rural areas, a new study finds.

The results, which are based on body shape rather than overall beauty, showed that in cities the most attractive gals had higher social and psychological well-being. That same link wasn't found for country residents.

The researchers suggest with higher population densities, cities offer more potential friends and sexual partners, allowing city folks to be choosier and so theoretically able to select the cream of the crop to associate with.

Peer-To-Peer Review: How ‘Climategate’ Marks The Maturing Of A New Science Movement, Part I


From Watt's Up With That?:

How a tiny blog and a collective of climate enthusiasts broke the biggest story in the history of global warming science – but not without a gatekeeper of the climate establishment trying to halt its proliferation.

It was triggered at the most unlikely of places. Not in the pages of a prominent science publication, or by an experienced muckraker. It was triggered at a tiny blog – a bit down the list of popular skeptic sites. With a small group of followers, a blog of this size could only start a media firestorm if seeded with just the right morsel of information, and found by just the right people. Yet it was at this location that the most lethal weapon against the global warming establishment was unleashed.

From The Montreal Gazette/Reuters:

Prolonged exposure to cocaine can cause permanent changes in the way genes are switched on and off in the brain, a finding that may lead to more effective treatments for many kinds of addiction, U.S. researchers said.

A study in mice by Ian Maze of Mount Sinai School of Medicine in New York and colleagues found that chronic cocaine addiction kept a specific enzyme from doing its job of shutting off other genes in the pleasure circuits of the brain, making the mice crave the drug even more.

No More Power Lines?

Sign of the past? Superconductor cables could replace transmission lines,
such as these in Los Banos, Calif. Newscom/file


From The Christian Science Monitor:

Buried super-cooled electrical cables may replace towering transmission lines and carry solar and wind energy efficiently over long distances.

Abundant solar and wind power lies across America’s vast plains and deserts, but getting that distant renewable energy to cities without wrecking vistas and raising lawsuits over transmission lines is a sizable hurdle for green-leaning utility companies. Thousands of miles of towering electrical lines will be needed before big alternative-energy projects can take hold. Yet such power lines portend years of legal snarls over the not-in-my-backyard problem.

From The Daily Mail:

Britain is on the brink of a massive expansion in foods containing controversial 'grey goo' nanoparticles, according to the former head of the Food Standards Agency.

Low-calorie chocolate and beer that doesn't go flat could be on sale within just five years, Lord Krebs said last night.

However, he and other peers believe there will be no requirement for the hi-tech products to be labelled as containing nanoparticles - microscopic compounds that can worm their way into the brain, liver and kidneys with unknown consequences.

You Won't Find Consciousness In The Brain

Consciousness in action? It is tempting to think that's what is going on - but wrong
(Image: Hans Neleman/Getty)


From New Scientist:

MOST neuroscientists, philosophers of the mind and science journalists feel the time is near when we will be able to explain the mystery of human consciousness in terms of the activity of the brain. There is, however, a vocal minority of neurosceptics who contest this orthodoxy. Among them are those who focus on claims neuroscience makes about the preciseness of correlations between indirectly observed neural activity and different mental functions, states or experiences.

Hominids Went Out of Africa On Rafts


From Wired Science:


ANAHEIM, Calif. — Human ancestors that left Africa hundreds of thousands of years ago to see the rest of the world were no landlubbers. Stone hand axes unearthed on the Mediterranean island of Crete indicate that an ancient Homo species — perhaps Homo erectus — had used rafts or other seagoing vessels to cross from northern Africa to Europe via at least some of the larger islands in between, says archaeologist Thomas Strasser of Providence College in Rhode Island.

'Wildlife In Crisis' In Frozen UK

From The BBC:

Britain's wildlife is being pushed to "the brink of a crisis" as sub-zero temperatures continue to grip the nation, according to conservationists.

The Royal Society for the Protection of Birds (RSPB) is organising emergency feeding of several threatened species, including bitterns and cirl buntings.

The RSPB is also asking people to feed garden birds, which are struggling to find food in the freezing weather.

The harsh winter could hit bird numbers "for many years to come", they warn.

Warmer Climate Could Stifle Carbon Uptake By Trees, Study Finds

A surprising new CU-Boulder study indicates subalpine forests in the West will soak up less carbon dioxide as the climate warms and the growing seasons lengthen. (Credit: Image courtesy Steve Miller, CIRES)

From Science Daily:

Science Daily (Jan. 8, 2010) — Contrary to conventional belief, as the climate warms and growing seasons lengthen subalpine forests are likely to soak up less carbon dioxide, according to a new University of Colorado at Boulder study.

As a result, more of the greenhouse gas will be left to concentrate in the atmosphere.

As Elvis Turns 75, Celebrity Worship Alive And Well

From Live Science:

If Elvis were alive, he'd be 75 on Friday. While his musical style and gyrations may have been unique, Elvis Presley's stardom and swooning fans can be explained by simple psychology, trends in technology and pop culture, and a look at our ancestors, all of which reveals why celebrity worship is on the rise.

"The Elvis phenomenon is only a case study of a wider psychological phenomenon," said James Houran, a clinical psychologist and president of 20/20 Skills, a human resources company.

Why "Green" Wine Is Catching On


From CBS News:

California Wineries Try To Set An Example Of What's Possible With Existing Technologies.

(AP) John Conover was looking for the best place to grow the Napa Valley's famous cabernet sauvignon grapes. Turns out the same southwest-facing, sunny hillside that gives him great grapes also raises a mean crop of solar panels.

"We wanted to be as green as we can be," says Conover, a partner in the Cade winery, which is on track for Gold certification under the U.S. Green Building Council's LEED (Leadership in Energy and Environmental Design).

Green wine is catching on.

From New Scientist:

A MIGRANT makes a furtive dash across an unwalled rural section of a national border, only to be confronted by a tracked robot that looks like a tiny combat tank - with a gimballed camera for an eye. As he passes the bug-eyed droid, it follows him and a border guard's voice booms from its loudspeaker. He has illegally entered the country, he is warned, and if he does not turn back he will be filmed and followed by the robot, or by an airborne drone, until guards apprehend him.

Thieves Use Google Earth To Find And Plunder Wineries' Solar Panels

Solar-Powered Vineyards "Just leave me in peace to tend to my wine" Langetwins Winery and Vineyards

From Popular Science:

Google's "do no evil" motto fails to halt heartless bandits.

Hot on the heels of news about Google's new energy venture comes this sorrowful tale about renewable energy. NPR reports on enterprising thieves who used Google Earth to do evil, and specifically to find California wineries with solar panels for the taking.

Yes, even the criminal underworld has embraced clean tech in the 21st century. Many thieves have reportedly used trucks to simply crash winery gates and steal up to 70 panels at a time. Local sheriff deputies speculate that online tools such as Google Earth might make it particularly easy to locate possible targets -- more than 400 panels worth over $1,000 each were stolen from Napa Valley vineyards in 2009.

Coral Reefs Are Evolution Hotspot

The reefs are centres of evolution as well as biodiversity.

From The BBC:

Coral reefs give rise to many more new species than other tropical marine habitats, according to a new study.

Scientists used fossil records stretching back 540 million years to work out the evolution rate at reefs.

They report in the journal Science that new species originate 50% faster in coral reefs than in other habitats.

The team says its findings show that the loss of these evolution hotspots could mean "losing an opportunity to create new species" in the future.

From Live Science:

Science Daily (Jan. 8, 2010) — For the last 20 years, the best models of planet formation -- or how planets grow from dust in a gas disk -- have contradicted the very existence of Earth. These models assumed locally constant temperatures within a disk, and the planets plunge into the Sun. Now, new simulations from researchers at the American Museum of Natural History and the University of Cambridge show that variations in temperature can lead to regions of outward and inward migration that safely trap planets on orbits.
