Three Questions: The Internet's Next Generation

From Voice of America:

Add this to the list of things you didn't know you had to worry about: the most commonly used version of the Internet is almost out of room.

The global organization that helps coordinate the allocation of Internet addresses is warning only about 200 million are left. That may sound like a lot, but the Number Resource Organization says more than 200 million addresses were assigned in just the last nine months.

The Other 'G' Spot

From Wall Street Journal:

At the beginning of the 20th century the British psychologist Charles Spearman "discovered" the idea of general intelligence. Spearman observed that students' grades in different subjects, and their scores on various tests, were all positively correlated. He then showed that this pattern could be explained mathematically by assuming that people vary in special abilities for the different tests as well as a single general ability—or "g"—that is used for all of them.

How One Company Games Google News

Note the second cluster of stories produced by a Google News search for "iTunes" yesterday afternoon. All of those Red Label News stories were basically the same: spammy SEO-keywords alongside Web ads. (Credit: Screenshot by Tom Krazit/CNET)

From CNET News:

Red Label News is not exactly a household name. But yesterday afternoon, it was one of the top news sources on Google News for stories about Apple's iTunes song previews.

How'd that happen? Red Label News, it appears, is a cleverly designed collection of links and headlines meant to game Google News rankings.

How To Use Google For Hacking

From Go Hacking:

Google serves almost 80 percent of all search queries on the Internet, proving itself as the most popular search engine. However Google makes it possible to reach not only the publicly available information resources, but also gives access to some of the most confidential information that should never have been revealed. In this post I will show how to use Google for exploiting security vulnerabilities within websites. The following are some of the hacks that can be accomplished using Google.

Putting Ice On Injuries Could Slow Healing

This discovery turns the conventional wisdom that swelling must be controlled in order to encourage healing and prevent pain Photo: CORBIS

From The Telegraph:

Slapping a packet of frozen peas on a black eye or a sprained ankle may prevent it getting better, new research suggests.

For years, people have been told to freeze torn, bruised or sprained muscles to reduce the swelling.

But now for the first time, researchers have found that it could slow down the healing as it prevents the release of a key repair hormone.

The Real Reason Women Outlive Men: It's All A Matter Of Breeding

From The Independent:

The reason women live longer than men – and why the final act of sex discrimination favours females over males – may at long last have a scientifically valid explanation.

Scientists believe we are close to understanding why men on average die younger than women. Life expectancy in Britain has risen steadily for both sexes over the past few decades and even though the gender gap has narrowed, women are still significantly more likely to live longer than men.

Exoskeleton Helps the Paralysed Walk Again

From New Scientist:

Amanda Boxtel, a wheelchair user, is about to stand up. A skiing accident 18 years ago partially severed her spinal cord leaving her paralysed from the waist down. She slowly pushes herself out of the chair with crutches, teeters backward for a second, then leans forward – and takes a step. Soon she is walking around the warehouse in Berkeley, California, under her own direction.

From Science Daily:

ScienceDaily (Oct. 8, 2010) — Using Australian telescopes, Swinburne University astronomy student Andy Green has found 'living dinosaurs' in space: galaxies in today's Universe that were thought to have existed only in the distant past.

The report of his finding -- Green's first scientific paper -- appears on the cover of the Oct. 7 issue of Nature.

From Live Science:

What new methods will allow us to create biofuel from plants? Garret Suen, a computational microbiologist at the University of Wisconsin-Madison (UW) in the Department of Bacteriology is trying to find out. Suen is a post-doctoral researcher working in the lab of Cameron Currie and in January of 2011, he will be joining the faculty in the Department of Bacteriology and starting up his own lab and research program. Suen grew up in Toronto (before moving to Calgary for college), and being from Canada, he thoroughly enjoys Wisconsin winters. Suen’s current work at UW centers on how to convert cellulose found in plants into a fermentable sugar that can be used to make ethanol for fuel.

'Mini-Pompeii' Found In Norway

From Discovery News:

Norwegian archaeologists have unearthed a Neolithic “mini Pompeii” at a campsite near the North Sea, they announced this week.

Discovered at Hamresanden, not far from Kristiansand’s airport at Kjevik in southern Norway, the settlement has remained undisturbed for 5,500 years, buried under three feet of sand.

“We expected to find an 'ordinary' Scandinavian Stone Age site, badly preserved and small. Instead, we discovered a unique site, buried under a thick sand layer,” lead archaeologist Lars Sundström, of the Museum of Cultural History at the University in Oslo, told Discovery News.

Giant Moon Collision 'May Have Formed Saturn's Rings'

Saturn's rings are largely made up of icy chunks

From The BBC:

Saturn's rings may have formed when a large moon with an icy mantle and rocky core spiralled into the nascent planet.

A US scientist has suggested that the tidal forces ripped off some of the moon's mantle before the actual impact.

The theory could shed light on the rings' mainly water-ice composition that has puzzled researchers for decades.

The scientist announced her idea at a conference in Pasadena, US.

Could An 'Elixir Of Life' Really Increase Your Lifespan?

From New Scientist:

A chemical elixir can add 10 years to your life! According to the media, anyway. How much of the claim that an amino acid cocktail can boost longevity should be taken with a pinch of salt?

For starters, the study was carried out in mice. Giuseppe D'Antona at Pavia University in Italy and his colleagues added a cocktail of three branched-chain amino acids (BCAA) - isoleucine, leucine and valine - to the feed of young nine-month-old mice.

Comet May Not Have Rocked Stone Age World

From Live Science:

While most scientists agree that a large object from space likely crashed into Earth and led to the eventual demise of the dinosaurs, a new study takes aim at theories that suggest similar events spelled bad news for large animals and Stone Age hunters nearly 13,000 years ago.

For about three years, scientists have debated over what caused drastic climate changes and gaps in the archaeological record at the end of the Pleistocene Epoch, a period of time spanning from about 1.8 million to 11,500 years ago.

From Discovery Magazine:

Save the date: Less than 3.7 billion years from now, the world is going to end, according to a new study.

A new study suggests the universe and everything in it could end within the Earth's lifespan -- less than 3.7 billion years from now -- and we won't know it when it happens.

But one expert says the result isn't valid because the researchers chose an arbitrary end point.

The universe began in a Big Bang about 13.7 billion years ago and has been expanding at an ever accelerating rate ever since.
