Average Net User Now Online 13 Hours Per Week

From CNET:

How much time do you spend online each week? If you're an average Net user, a new poll shows, it's around 13 hours--excluding e-mail.

The Harris Interactive poll, released Wednesday, found that 80 percent of U.S. adults go online, whether at home, work, or elsewhere. Those who surf the Net spend an average of 13 hours per week online, but that figure varies widely. Twenty percent are online for two hours or less a week, while 14 percent are there for 24 hours or more.

The Operation To 'Cure' High Blood Pressure: How It Works

From The Telegraph:

High blood pressure increases the risk of heart disease, stroke, kidney failure and in general the higher the blood pressure, the greater the risk.

LIfestyle improvements such as weight loss if necessary, exercise, stopping smoking and a low salt diet can reduce high blood pressure but many will require medication.

There are an estimated 15 million people in Britain with raised blood pressure and drugs to treat the condition are amongst the most commonly prescribed drugs.

2010 Preview: The Polyglot Web

Mapping the internet as it goes truly global (Image: Matthew Hurst/SPL)

From The New Scientist:

Imagine what browsing the web would be like if you had to type out addresses in characters you don't recognise, from a language you don't speak. It's a nightmare that will end for hundreds of millions of people in 2010, when the first web addresses written entirely in non-Latin characters come online.

Net regulator ICANN - the Internet Corporation for Assigned Names and Numbers - conceded in October that more than half of the 1.6 billion people online use languages with scripts not fully compatible with the Latin alphabet. It is now accepting applications for the first non-Latin top level domains (TLDs) - the part of an address after the final "dot". The first national domains, counterparts of .uk or .au, should go live in early 2010. So far, 12 nations, using six different scripts, have applied and some have proudly revealed their desired TLD and given a preview of what the future web will look like.

GAO Warns Space Station May Be A Bust

From Discovery News:

The Government Accountability Office has some somber words for U.S. taxpayers: After 25 years of work and billions of dollars, we may not get our money’s worth out of the International Space Station.

There are several reasons for the situation, the GAO said in a new report, including the fact that there currently is no money to keep the station operational past 2015. NASA and its international partners in the program -- Russia, Europe, Canada and Japan -- are just beginning to ramp up research after a 12-year construction effort ends next year.

Europe's Goce Satellite Probes Earth's Gravity

A first glimpse at the data coming down from Europe's Goce satellite

From The BBC:

Europe's Goce satellite is returning remarkable new data on the way the pull of gravity varies across the Earth.

Scientists say its first maps clearly show details not seen in previous space and ground measurements.

Goce was launched by the European Space Agency (Esa) in March from the Plesetsk Cosmodrome in north-west Russia.

Its information is expected to bring new insights into how the oceans move, and to frame a universal system to measure height anywhere on the planet.

From The Science Daily:

Science Daily (Dec. 25, 2009) — Scientists at UC Santa Barbara have made a major discovery in how the brain encodes memories. The finding, published in the December 24 issue of the journal Neuron, could eventually lead to the development of new drugs to aid memory.

The team of scientists is the first to uncover a central process in encoding memories that occurs at the level of the synapse, where neurons connect with each other.

Pain Pills Could Ease Hurt Feelings

From Live Science:

Getting the snub from friends can feel like a slap in the face. Now researchers say treating such social pain may be as easy as popping a pain pill. They warn, however, that more research is needed before anyone tries the approach.

The finding builds on research showing that psychological blows not only feel like they hurt us, they actually do. For instance, scientists have found a gene linked with both physical pain and a person's sensitivity to rejection. And some of the same brain regions are linked with both pain types.

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.

Security In The Ether

Cloud crowd: Some 4,000 servers hum at IBM’s cloud computing center in San Jose, CA.

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.

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.
