Google Maps Rolls Out Trail And Street Directions For Cyclists

A cyclist crosses the Brooklyn Bridge. Starting today, Google Maps will feature a biking layer, where users can plan their route according to the grade of the hills or the level of traffic congestion. Newscom

From The Christian Science Monitor:

A new layer on Google Maps will let cyclists access maps of 150 cities around the US. It's a bike geek's dream come true.

On Wednesday morning, Google added bike directions and trail information to Google Maps – a long-awaited functionality that product manager Shannon Guymon said would "encourage folks to hop on their bikes." By selecting the "Bicycling" layer on Google Maps, cyclists can now see the closest trails and bike lanes in area, or plan around particularly congested urban arteries and calf-busting hill climbs.

Life Is Shorter For Men, But Sexually Active Life Expectancy Is Longer


From Science Daily:

Science Daily (Mar. 10, 2010) — At age 55, men can expect another 15 years of sexual activity, but women that age should expect less than 11 years, according to a study by University of Chicago researchers published early online March 10 by the British Medical Journal. Men in good or excellent health at 55 can add 5 to 7 years to that number. Equally healthy women gain slightly less, 3 to 6 years.

Donating A Kidney Doesn't Shorten Donor's Life


From Live Science:

People who donate one of their kidneys are likely to live just as long as someone with two healthy kidneys, assuming they survive the initial somewhat riskier period.

A new study, which involved more than 80,000 live kidney donors in the United States and looked at survival rates over a 15-year period, is the first to use data from a national level, rather than from single-transplant centers with similar populations.

Large Hadron Collider To Shut Down, Not Baguette This Time

From Techeye.net:

World record collision energies aren’t enough - it needs more power!!

The Large Hardon Collider (LHC) is to shut down at the end of 2011, just in time to cause the (speculated) end of the world by 2012.

According to reports, the atom smashing machine needs to fix design and safety issues which is stopping it from reaching its potential. Apparently, world record collisions of 7 trillion electron volts isn’t enough - the LHC needs to be made safer before collisions at about twice that level can start.

The LHC is the world’s largest and highest-energy particle accelerator built by the European Organisation for Nuclear Research (CERN), with the goal of colliding protons or lead ions at very high energy, recreating the conditions after the Big Bang.

Music And lyrics: How The Brain Splits Songs

When tunes and lyrics diverge

From The New Scientist:

Your favourite song comes on the radio. You hum the tune; the lyrics remind you of someone you know. Is your brain processing the words and music separately or as one? It's a hotly debated question that may finally have an answer.

People with aphasia, who can't speak, can still hum a tune, suggesting music and lyrics are processed separately. Yet brain scans show that music and language activate the same areas, which might mean the brain treats them as one signal.

Opposites Do Attract As 'Stressed Men Make Odd Sexual Decisions', Study Suggests

The study could explain why some couples end up together for example Nicholas Sarkozy, the French President and his wife Carla Bruni-Sarkozy.

From The Telegraph:

Opposites really do attract in people, according to scientists who researched the psychology of sexual attraction.

Researchers in Germany discovered that stressed men made unconventional choices in sexual preferences.

Scientists at the University of Trier found that young men who were under pressure preferred erotic pictures of female nudes who were had the opposite facial expressions to themselves.

From Christian Science Monitor:

Dusty northern Kenya doesn't look like a laboratory, but across its dry plains, cattle herders are pioneering a new way to fend off poverty and teaming up with unlikely partners – insurance agents.

The two groups have been brought together by the International Livestock Research Institute (ILRI), headquartered in Kenya's capital, Nairobi. A few years ago, scientists at ILRI wondered if a new innovation, called weather-indexed insurance, might help impoverished cattle farmers survive the loss of their cows during times of drought.

From Cosmos:

PARIS: DNA from the fossilised eggshells of extinct birds - including iconic giants such as the moa and elephant bird - have been extracted for the first time, Australian scientists have reported.

The achievement marks a major step towards drafting the genome of birds wiped out by human greed, although the scientists warn this does not mean an extinct species should - or even can - be resurrected in the style of Jurassic Park.

US Still Responsible For Most CO2 Emissions

From New Scientist:

Europeans import nearly twice as much carbon dioxide per head as US citizens – but the US still holds the dubious distinction of being the world's largest emitter.

The Carnegie Institution for Science in Stanford, California, reports that in 2004 23 per cent of global CO2 emissions – some 6.2 gigatonnes – went in making products that were traded internationally. Most of these products were exported from China and other relatively poor countries to consumers in richer countries. Some countries, such as Switzerland, "outsourced" over half of their carbon dioxide emissions in this way because they have a high import-to-export ratio of such energy-intensive goods as consumer electronics, motor vehicles and machinery.
