From Technology Review:

Researchers have identified a genetic tweak that can slow aging in mice.

By disabling a gene involved in an important biochemical signaling pathway, scientists have discovered a way to mimic the well-known anti-aging benefits of caloric restriction, allowing mice to live longer and healthier lives. This finding, published online today in Science, offers a promising drug target for combating the many health problems associated with aging.

US Relaxes Grip On The Internet

From The BBC:

The US government has relaxed its control over how the internet is run.

It has signed a four-page "affirmation of commitments" with the net regulator Icann, giving the body autonomy for the first time.

Previous agreements gave the US close oversight of Icann - drawing criticism from other countries and groups.

The new agreement comes into effect on 1 October, exactly 40 years since the first two computers were connected on the prototype of the net.

"It's a beautifully historic day," Rod Beckstrom, Icann's head, told BBC News.

Elderly Women Sleep Better Than They Think, Men Sleep Worse

From Science Daily:

ScienceDaily (Oct. 1, 2009) — A study in the Oct.1 issue of the journal Sleep shows that elderly women sleep better than elderly men even though women consistently report that their sleep is shorter and poorer.

Women reported less and poorer sleep than men on all of the subjective measures, including a 13.2 minute shorter total sleep time (TST), 10.1 minute longer sleep onset latency (SOL), and a 4.2 percent lower sleep efficiency. When sleep was measured objectively, however, women slept 16 minutes lon¬ger than men, had a 1.2 percent higher sleep efficiency, and had less fragmented sleep.

From Time Magazine:

In recent years, efforts to combat drug-resistant bacteria have focused on the immediate goal of reducing rates of hospital-acquired infections. But now global health officials face an approaching crisis: the number of different antibiotics available to treat such infections when they do occur is dwindling because pharmaceutical companies have neglected to invest in the development of new types of drugs.

Apple’s Tablet Could Be Print Industry’s Lifeboat

From Gadget Lab:

The more you think about it, the more obvious it is that an Apple tablet would specialize in reviving dead-tree media (i.e., newspapers, magazines and books). All the rumors suggest the device would be a larger iPod Touch/iPhone with a 10-inch screen. Previously Wired.com argued that redefining print would would be a logical purpose for a gadget this size, and Gizmodo today has even more details to prove that this is Apple’s goal with the tablet.

Gizmodo’s Brian Lam cites two people related to The New York Times, who claim Apple approached them to talk about repurposing the newspaper onto a “new device.” Lam notes that Jobs has called the Times the “best newspaper in the world” in past keynotes. (I recall him saying that when introducing the iPhone’s web browser at Macworld Expo 2007.)

Disarmingly Cute: 8 Military Robots That Spy, Fly, And Do Yoga

From Discover Magazine:

A new generation of military robots are coming soon to a battlefield near you. These new battle bots are more WALL*E than ED-209—cute, small, and innocent-looking, rather than giant and murderous.

But while they may appear adorable, the latest generation of robotic warriors can do a lot more than box up trash. Here are a few examples of these cute but deadly robots in action—leaping walls, flipping trucks and…doing yoga?

Real or Fake? The World's Longest Basketball Shot

From Popular Science:

If we time the flight, we can then apply some ballpark approximations to determine whether the trajectory we see in the video conforms to that flight time. Using our stopwatch we observe that the ball is in the air for 3.8 seconds before passing through the basket. The horizontal distance to the basket from the launch point is approximately 50 meters, and the launch angle θ is about 20 degrees.

From CNET:

Google has added a few new filters to the search options panel it introduced last May, emphasizing speed and continuity on its search results pages.

The "show options" link at the top of a Google search results page brings up a number of filters on the left side of the search results page that allow searchers to refine their queries, allowing them to search just for content types like videos or search results from a certain timeline. Google is gradually rolling out some new options in that panel, allowing searchers to find results from the last hour or results posted in Google Books or Google News, said Nundu Janakiram, product manager in search.

The Skype Founders' Revenge Against eBay -- Time Magazine

Just when eBay thought it had figured out a way to unload a majority interest in Skype, along came the Scandinavian founders of the world's biggest provider of Internet telephony to sink the $1.9 billion deal — and perhaps Skype itself.

Niklas Zennstrom and Janus Friis are suing eBay, based in San Jose, Calif., and a consortium of investors that includes private-equity firms Silver Lake, Andreessen Horowitz (co-owned by Netscape's Marc Andreessen) and the Canada Pension Plan over the breach of a software-licensing agreement.

New Nobel Prizes Are 'Unlikely'

From The BBC:

Calls from a group of eminent scientists for new Nobel prizes look unlikely to prove successful.

The group had argued that the current range of prizes was too narrow to reflect the breadth of modern science.

The Nobel prizes are considered to be the most prestigious awards in science, and are limited to a few categories.

But a senior official from the Nobel Foundation has told BBC News that the categories were outlined in Alfred Nobel's will and would not change.

Raining Pebbles: Rocky Exoplanet Has Bizarre Atmosphere, Simulation Suggests

The exoplanet COROT-7b is close enough to its star that its "day-face" is hot enough to melt rock. Theoretical models suggest the planet has an atmosphere of the components of rock in gaseous form and lava or boiling oceans on its surface. (Credit: Image by ESO/L. Calcada)

From Science Daily:

ScienceDaily (Oct. 1, 2009) — So accustomed are we to the sunshine, rain, fog and snow of our home planet that we find it next to impossible to imagine a different atmosphere and other forms of precipitation.

To be sure, Dr. Seuss came up with a green gluey substance called oobleck that fell from the skies and gummed up the Kingdom of Didd, but it had to be conjured up by wizards and was clearly a thing of magic.

Loss Of Top Predators Causing Ecosystems To Collapse

From Live Science:

The catastrophic decline around the world of "apex" predators such as wolves, cougars, lions or sharks has led to a huge increase in smaller "mesopredators" that are causing major economic and ecological disruptions, a new study concludes.

The findings, published today in the journal Bioscience, found that in North America all of the largest terrestrial predators have been in decline during the past 200 years while the ranges of 60 percent of mesopredators have expanded. The problem is global, growing and severe, scientists say, with few solutions in sight.

From Scientific American:

A new study attempts to estimate the effects of climate change on global agriculture--and outline ways to mitigate its most dire consequences.

The people of East Africa once again face a devastating drought this year: Crops wither and fail from Kenya to Ethiopia, livestock drop dead and famine spreads. Although, historically, such droughts are not uncommon in this region, their frequency seems to have increased in recent years, raising prices for staple foods, such as maize.

From Time Magazine:

Figuring out the story of human origins is like assembling a huge, complicated jigsaw puzzle that has lost most of its pieces. Many will never be found, and those that do turn up are sometimes hard to place. Every so often, though, fossil hunters stumble upon a discovery that fills in a big chunk of the puzzle all at once — and simultaneously reshapes the very picture they thought they were building.

Will Computer Programs Replace Mozart?

From Discover Magazine:

Meet Emily Howell. She’s a composer who is about to have a CD released of sonatas she composed. So what makes her unique? She’s also a computer program.

Emily was created by University of California-Santa Cruz professor David Cope, who claims to be more of a music teacher than a computer scientist (he’s both). Cope has been working on combining artificial intelligence with music for 30 years—thereby challenging the idea that creating music should be limited to the human mind.
