Four Ways To Feed The World

From New Scientist:

IT IS humanity's oldest enemy. Despite all our science, a sixth of people in the developing world are chronically hungry. At a summit in Rome this week, world leaders reaffirmed a pledge to end hunger "at the earliest possible date".

The UN Food and Agriculture Organization (FAO) wanted them to promise to end hunger by 2025, but the delegates declined. They said instead that they would keep trying to meet their previous goal: to halve chronic hunger from 20 per cent of people in developing countries to 10 per cent by 2015 (see graph). But can they? Based on their performance so far, the FAO considers it "unlikely".

From The Telegraph:

Scientists have repaired the world's largest atom smasher and plan by this weekend to restart the fault-ridden Large Hadron Collider.

The 'Big Bang' machine was launched with great fanfare last year before its spectacular failure from a bad electrical connection.

This time the European Organization for Nuclear Research, known as CERN, is taking a cautious approach with the super-sophisticated equipment, said James Gillies, a spokesman. It cost about $10 billion, with contributions from many governments and universities around the world.

Insects May Have Consciousness And Could Even Be Able To Count, Claim Experts

A honeybee's brain weighs one mg and contains fewer than a million nerve cells

From The Daily Mail:

Insects with minuscule brains may be as intelligent as much bigger animals and may even have consciousness, it was claimed today.

Having a brain the size of a pinhead does not necessarily make you less bright, say researchers.

Computer simulations show that consciousness could be generated in neural circuits tiny enough to fit into an insect's brain, according to the scientists at Queen Mary, University of London and Cambridge University.

How To Explore Mars And Have Fun

Scientists hope the public's help will have a big impact on research.

From The BBC:

The US space agency needs your help to explore Mars.

A Nasa website called "Be A Martian" allows users to play games while at the same time sorting through hundreds of thousands of images of the Red Planet.

The number of pictures returned by spacecraft since the 1960s is now so big that scientists cannot hope to study them all by themselves.

The agency believes that by engaging the public in the analysis as well, many more discoveries will be made.

The new citizen-science website went live on Tuesday at http://BeAMartian.jpl.nasa.gov.

The site is just the latest to use crowdsourcing as a tool to do science.

From Live Science:

Though their long teeth look fearsome, male sabertooth cats may have actually been less aggressive than their feline cousins, a new study finds.

Commonly called the sabertoothed tiger, Smilodon fatalis was a large predatory cat that roamed North and South America about 1.6 million to 10,000 years ago, when there was also a prehistoric cat called the American lion. The study examined size differences between sexes of these large felines using clues from bones and teeth.

Senate Panel: 80 Percent of Cyber Attacks Preventable

From Threat Level:

If network administrators simply instituted proper configuration policies and conducted good network monitoring, about 80 percent of commonly known cyber attacks could be prevented, a Senate committee heard Tuesday.

The remark was made by Richard Schaeffer, the NSA’s information assurance director, who added that simply adhering to already known best practices would sufficiently raise the security bar so that attackers would have to take more risks to breach a network, “thereby raising [their] risk of detection.”

The Race To Build A 1000 mph Car

From New Scientist:

Strapped into a custom built seat, Andy Green prepares for the ride of his life. The pancake-flat desert stretches out for miles ahead. The computer indicates all systems are normal. He eases off the brakes and puts his foot down on the throttle. The jet engine roars into life. In precisely 42.5 seconds he'll be travelling 1000 mph. In a car.

"It's almost impossible to tell the difference between going supersonic in a car and in an aircraft," says Green. He is the only person on Earth who can say that from personal experience. Green was a fighter pilot for the UK Royal Air Force for 20 years, and he is also the fastest man on wheels. In 1997, driving a vehicle called ThrustSSC, he set the world land speed record of 763 miles per hour, becoming the first and only person to break the sound barrier in a car (761 mph under standard conditions). Now, together with the Bloodhound SSC design team, he's attempting to do it all over again, and then some.

Liquid Cooling Bags For Data Centers Could Trim Cost and Carbon By 90 Percent

The Iceotope Water-Cooling Component After the individual bags of coolant pull heat away from the individual server components, a water transfer system moves heat out of the data center, possibly for use in heating offices during cold weather. Iceotope

From Popular Science:

Server farms are undeniably awesome in that they store huge pools of data, enable such modern phenomena as cloud computing and Web-hosted email, and most importantly, make the Internet as it stands today possible. The downside: data centers get very, very hot. Cooling huge banks of servers doesn't just cost a lot, it eats up a lot of energy, and that generally means fossil fuels. UK-based Iceotope hopes to cut those costs by about 93 percent by wrapping servers in liquid coolant.

From The Telegraph:

Women should wear clothes that bare 40 per cent of their flesh to maximise their chances of attracting men, new scientific research indicates.

Striking the right balance between revealing too much and being too conservative in how much skin is on show has long been a dilemma for women when choosing the right outfit for a night out.

However, a study by experts at the University of Leeds has come to the rescue by calculating the exact proportion of the body that should be exposed for optimum allure.

Email Could Be 'Extinct Within A Decade' As Teens Turn To Twitter-Style Messaging

Photo: Email took 20 years to develop but may disappear within a decade, experts believe

From The Daily Mail:

Email could be extinct within a decade as millions of teenagers ditch it as their main form of communication, say researchers.

Youngsters have been shown to favour social networking sites and instant messaging instead.

The report found the electronic form of contact is already becoming 'grey mail' with the most devoted users being pensioners, followed by middle-aged Britons.

Although inboxes are still filling up daily all over the world, experts believe emails are dying out because they are too slow, too inconvenient and simply not fashionable any more.

From ABC News:

National Geographic Channel Program Documents Undersea Search for Japanese Super-Submarines.

With more time, military experts say, a fleet of revolutionary Japanese super-submarines could have changed the course of World War II.

Some were designed to launch bombers on kamikaze missions against New York City, Washington, D.C., and the Panama Canal. Others were thought to be twice as fast any other submarine used in the war.

None had the chance to execute their stealth missions against the U.S. mainland or critical targets in the Pacific during the war.

What Would Shackleton's Whisky Taste Like?

From the BBC:

After a century buried in the Antarctic ice, a rare batch of whisky that belonged to the polar explorer Sir Ernest Shackleton is to be recovered. So what might it taste like?

It's been on the rocks for the last 100 years, buried under two feet of Antarctic ice. Now the two cases of "Rare Old" brand Mackinlay and Co whisky are to be retrieved.

A team of New Zealand explorers heading out in January has been asked by Whyte & Mackay, the company that now owns Mackinlay and Co, to get a sample of the drink. The crates were left behind by Sir Ernest Shackleton when he abandoned his mission to the South Pole in 1909.

From Science Daily:

Science Daily (Nov. 17, 2009) — Using ESO's Very Large Telescope and its ability to obtain images as sharp as if taken from space, astronomers have made the first time-lapse movie of a rather unusual shell ejected by a "vampire star," which in November 2000 underwent an outburst after gulping down part of its companion's matter. This enabled astronomers to determine the distance and intrinsic brightness of the outbursting object.

It appears that this double star system is a prime candidate to be one of the long-sought progenitors of the exploding stars known as Type Ia supernovae, critical for studies of dark energy.

No Surprise: Coed Dorms Fuel Sex and Drinking

From Live Science:

It's no secret to students that coed dorms are more fun than same-sex dorms. But they can also fuel very unhealthy behavior that might otherwise be moderated.

A new study finds university students in coed housing are 2.5 times more likely to binge drink every week. And no surprise, they're also likely to have more sexual partners, the study found. Also, pornography use was higher among students in coed dorms.

Some 90 percent of U.S. college dorms are now coed.

From The Guardian:

X-rays of mummies reveal atherosclerosis, suggesting there may be more to heart disease than bad diet and smoking.

Heart disease plagued human society long before fry-ups and cigarettes came along, researchers say. The upper classes of ancient Egypt were riddled with cardiovascular disease that dramatically raised their risk of heart attacks and strokes.

Doctors made the discovery after taking hospital X-ray scans of 20 Egyptian mummies that date back more than 3,500 years.
