Polar Bears Forced To Land And Water

Polar bears depend on sea ice for hunting, breeding and denning. The bears wait for seals to pop up through breathing holes in the ice, but since the ice is melting earlier and earlier in the year, polar bears are shifting there habitat to land and water, and may be missing out on hunting opportunities.

From Live Science:

As Arctic sea ice melts, polar bears are changing their habitat, shifting from their preferred ice hunting grounds to land and open water, according to a new long-term study.

The findings have implications for people as well as polar bears, since the shift makes it more likely that humans will encounter these large animals on land, the researchers say.

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.

China Threatens To Slam Brakes On Price Of Lead

E-bikes were a feature of the Beijing Olympic Games last year, but reclassifying some of them as motorcycles will have an impact far beyond sales figures

From Times Online:

After a surge of more than 125 per cent, the price of lead ends the year in limbo — its future at the mercy of Chinese bureaucracy, the stroke of a pen and the legal status of 100 million electric bicycles.

The cycles in question, known as “e-bikes”, are battery-enhanced machines that are the darlings of the modern, urban Chinese. More than 20 million were sold this year, putting a vast army of commuters, unable to afford cars or motorcycles — and without licences — on the roads at a sedate maximum speed of 12 km/h (7½ mph).

Hubble Telescope Captures Earliest Images Of Universe - When It Was Just A 'Baby' At 600 Million Years

Deep space time: the Hubble picture shows the earliest ever seen galaxies which are circled in the boxes in the inset images on the left

From The Daily Mail:

The Hubble telescope has captured the earliest image yet of the universe - just 600 million years after the Big Bang.

It is the most complete picture taken in near-infrared light of the early universe, showing the first infant star clusters.

To give some perspective, the light left these galaxies 8billion years before our own Sun and Earth had even formed.

Scientists released the 'baby pictures' at a meeting of the American Astronomical Society.

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.

From Science Daily:

Science Daily (Jan. 7, 2010) — When scientists confirmed in October that they had detected the first rocky planet outside our solar system, it advanced the longtime quest to find an Earth-like planet hospitable to life.

Rocky planets -- Earth, Mercury, Venus and Mars -- make up half the planets in our solar system. Rocky planets are considered better environments to support life than planets that are mainly gaseous, like the other half of the planets in our system: Jupiter, Saturn, Uranus and Neptune.

What An Anti-Climax: G-Spot Is A Myth

While 56% of women overall claimed to have a G-spot,
they tended to be younger and more sexually active.

From Times Online:

A sexual quest that has for years baffled millions of women — and men — may have been in vain. A study by British scientists has found that the mysterious G-spot, the sexual pleasure zone said to be possessed by some women but denied to others, may not exist at all.

The scientists at King’s College London who carried out the study claim there is no evidence for the existence of the G-spot — supposedly a cluster of internal nerve endings — outside the imagination of women influenced by magazines and sex therapists. They reached their conclusions after a survey of more than 1,800 British women.

The Rise Of Robodoc

The Acrobot Robot, which helps orthopaedic surgeons
to carry out computer navigated partial knee replacements

From The Independent:

Many operations are becoming less invasive and more efficient due to the growth of cyber-surgery. Nina Lakhani on a British medical success story.

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.

From Health.com:

1. You won't have to pay more and more and more and more each year.
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.

2. You'll inhale fewer germs.
New research suggests cigarettes are crawling with germs, which can be inhaled along with the smoke. It’s not clear if the germs can make you sick, but the yuck factor is undeniable.
