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 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.

Top 10 Places You Can’t Go

#1: RAF Menwith Hill

RAF Menwith Hill is a British military base with connections to the global ECHELON spy network. The site contains an extensive satellite ground station and is a communications intercept and missile warning site and has been described as the largest electronic monitoring station in the world. The site acts as a ground station for a number of satellites operated by the US National Reconnaissance Office, on behalf of the US National Security Agency, with antennae contained in a large number of highly distinctive white radomes, and is alleged to be an element of the ECHELON system. ECHELON was reportedly created to monitor the military and diplomatic communications of the Soviet Union and its Eastern Bloc allies during the Cold War in the early 1960s, but since the end of the Cold War it is believed to search also for hints of terrorist plots, drug dealers’ plans, and political and diplomatic intelligence. It has also been involved in reports of commercial espionage and is believed to filter all telephone and radio communications in the nations which host it – an extreme violation of privacy.

First Earth-Like Planet Spotted Outside Solar System Likely A Volcanic Wasteland

How similar is exoplanet CoRoT-7b to Earth? The newly discovered extra-solar planet (depicted in the above artist's illustration) is the closest physical match yet, with a mass about five Earths and a radius of about 1.7 Earths. Also, the home star to CoRoT-7b, although 500 light years distant, is very similar to our Sun. Unfortunately, the similarities likely end there, as CoRoT-7b orbits its home star well inside the orbit of Mercury, making its year last only 20 hours, and making its peak temperature much hotter than humans might find comfortable.

While surgeons are often criticised for their brusque bedside manner, few could accurately be described as robots. This is going to change as surgical consultations increasingly involve robotic systems to help diagnose, plan operations and reassure patients.

The development of robotic systems, both active and passive, is enabling surgeons to use keyhole techniques in hard-to-reach areas not previously thought possible. Britain is at the forefront of many advances. Collaborations between NHS surgeons, universities and private companies enable Britain to develop robotics more quickly and cheaply than North American and European counterparts.

Yup, taxes will almost certainly continue to go up. New Jersey, Vermont, and Connecticut are among the states leaning harder on smokers for revenue, but even some tobacco-growing states are beginning to milk the coffin-nail cash cow. Lawmakers' reasoning: There is evidence that price increases cause smokers to reduce consumption. And the medical costs of smoking are astronomical—a huge burden to the states.

Chilling Out In The Coldest Place on Earth

Just when you think it can't get any colder (Image: Michael Studinger/Lamont Doherty Earth Observatory/Columbia University)

From New Scientist:

VOSTOK Station in Antarctica currently holds the crown for the coldest place on the planet. It recorded -89.2 °C on 21 July 1983. But it could get even colder, with temperatures dropping to about -96 °C, if "perfect" cold-weather conditions prevail.

John Turner of the British Antarctic Survey and colleagues analysed the weather conditions that brought about the record chill and found it was caused by an unusual, near-stationary atmospheric vortex. "This isolated Vostok and prevented the waves of warm air that normally come up from the ocean," says Turner. After that big chill, the temperature bounced up by over 20 °C in one day (Journal of Geophysical Research - Atmospheres, DOI: 10.1029/2009JD012104).
