Alcohol Substitute That Avoids Drunkenness And Hangovers In Development

From The Telegraph:

An alcohol substitute that mimics its pleasant buzz without leading to drunkenness and hangovers is being developed by scientists.

The new substance could have the added bonus of being "switched off" instantaneously with a pill, to allow drinkers to drive home or return to work.

The synthetic alcohol, being developed from chemicals related to Valium, works like alcohol on nerves in the brain that provide a feeling of well being and relaxation.

Unveiled: China's 245mph Train Service Is The World's Fastest... And It Was Completed In Just FOUR Years

Travellers board a high-speed train which heads to Guangzhou
in Wuhan, Hubei province, on Boxing Day

From The Daily Mail:

In the week that Britain's high speed rail link closed down because the wrong sort of snow interfered with the engine's electronics, China unveiled the world's fastest train service on one of the coldest days of the year.

Days after thousands of passengers were left stranded when Eurostar services were cancelled, China's new system connects the modern cities of Guangzhou and Wuhan at an average speed of 217mph - and it took just four years to build.

From Technology Review:

Information technology's next grand challenge will be to secure the cloud--and prove we can trust it.

In 2006, when Amazon introduced the Elastic Compute Cloud (EC2), it was a watershed event in the quest to transform computing into a ubiquitous utility, like electricity. Suddenly, anyone could scroll through an online menu, whip out a credit card, and hire as much computational horsepower as necessary, paying for it at a fixed rate: initially, 10 cents per hour to use Linux (and, starting in 2008, 12.5 cents per hour to use Windows). Those systems would run on "virtual machines" that could be created and configured in an instant, disappearing just as fast when no longer needed. As their needs grew, clients could simply put more quarters into the meters. Amazon would take care of hassles like maintaining the data center and network. The virtual machines would, of course, run inside real ones: the thousands of humming, blinking servers clustered in Amazon's data centers around the world. The cloud computing service was efficient, cheap, and equally accessible to individuals, companies, research labs, and government agencies.

From New Scientist:

West Virginia. It is 6 am on an April morning in 1960 and Frank Drake is freezing cold. He peers up towards the focal point of the radio telescope. He mounts a flimsy ladder to the top and climbs into a space about the size of a garbage can. For the next 45 minutes, he tunes the receiver inside, which feels like starting an old car. He climbs back down and begins to listen.

From Discovery News:

It's been five years since an 800-mile-long (1,300 km) section of colliding plates in Earth's crust unzipped and unleashed a 9.3 megathrust earthquake from Sumatra to the Andaman Islands. The rupture moved a block of earth as long as California about 30 feet. At least 230,000 people perished from the quake and the tsunamis that followed. We're remembering the disaster, as well as looking at the many lessons and discoveries been gleaned from it -- lessons that should never be forgotten.

Is Running Bad For Your Knees? Maybe Not.

From Time Magazine:

Perhaps because it seems intuitively true, the notion persists that running, especially when done long-term and over long distances, is bad for the joints. Indeed it would be hard to think otherwise when, with each foot strike, a runner's knee withstands a force equal to eight times his body weight — for a 150-lb. person, that's about 1,200 lbs. of impact, step after step.

Troubleshooters That Block Cancer

From The BBC:

Scientists have shown how a family of "limpet-like" proteins play a crucial role in repairing the DNA damage which can lead to cancer.

They hope the finding could pave the way for a new type of drug which could help kill cancer cells, and promote production of healthy replacements.

The proteins seem to have a remarkable ability to zero in on damaged areas.

The breakthrough, uncovered independently by two teams, appears in the journal Nature.

From Science Daily:

Science Daily (Dec. 26, 2009) — Going back for a second dessert after your holiday meal might not be the best strategy for living a long, cancer-free life say researchers from the University of Alabama at Birmingham. That's because they've shown exactly how restricted calorie diets -- specifically in the form of restricted glucose -- help human cells live longer.

This discovery, published online in The FASEB Journal, could help lead to drugs and treatments that slow human aging and prevent cancer.

From Live Science:

In the spring of 1969, Terry Tickhill Terrell was 19 and an undergraduate chemistry major at Ohio State University, bored with her lab work and restless. She had never traveled more than 250 miles from the Barnesville, Ohio farm where she grew up.

One day, after reading an article in the school newspaper about a graduate student who had just returned from Antarctica, Terrell decided that that was where she wanted to go.

From Technology Review:

Today's stock market has become a world of automated transactions executed at lightning speed. This high-frequency trading could make the financial system more efficient, but it could also turn small mistakes into catastrophes.

If Manoj Narang is about to bring down the markets, he's certainly relaxed about it. Narang, who wears a goatee and wire-frame glasses, is casually dressed in a brown shirt and dark gray sweatshirt. Sitting on a swivel chair with one leg tucked under the other, he seems positively composed, especially for a man who has just bought and sold 15 million shares with a total value of $600 million. For Narang, however, such volume represents just the start of a normal day. Though it's about noon on a Friday morning, he has barely begun.

Ouch! We Really CAN Feel The Physical Pain Of Others

In a recent study, a third of subjects claimed to feel real pain in the same
part of the body as the victim they were watching

From The Daily Mail:

For most of us the expression 'feeling someone else's pain' is simply a way of saying we sympathise with their sadness or discomfort.

But there are some who don't just have an emotional reaction to another's agony - they feel genuine physical pain as well, researchers have found.

The finding could explain why some people are more sympathetic to other people's misery.

Surfing A Wave Of Californian Sunshine As America Looks For Renewable Future

The eSolar plant in the Mojave Desert generates enough electricity to power 4,000 homes

From Times Online:

On a dry, scrubby plain on the edge of the Mojave Desert north of Los Angeles, 24,000 mirrors track the Sun’s progress across a clear, blue sky. The neat ranks of heliostats and the computer algorithm that moves them make the Sierra SunTower plant a focal point for a novel type of power generation and a new wave of energy companies looking to turn the search for renewables into successful businesses.

Solar tower technology uses mirrors to reflect sunlight on to a thermal receiver atop a tower. The reflected sunlight boils water inside the receiver to create superheated steam at 440C (824F), which drives a turbine and generates electricity.
