From Science Daily:

ScienceDaily (Oct. 2, 2009) — Tiny organisms that covered the planet more than 250 million years ago appear to be a species of ancient fungus that thrived in dead wood, according to new research published October 1 in the journal Geology.

The researchers behind the study, from Imperial College London and other universities in the UK, USA and The Netherlands, believe that the organisms were able to thrive during this period because the world's forests had been wiped out. This would explain how the organisms, which are known as Reduviasporonites, were able to proliferate across the planet.

From Live Science:

About three years ago, Emily Beal — a graduate student in geosciences at Penn State —eagerly boarded the deep-diving research submersible called Alvin, bound for the bottom of the ocean.

After squeezing into Alvin’s titanium sphere, Beal began her plunge to the ocean floor with more than a tad of claustrophobia. Alvin was just big enough to hold her, the submersible’s pilot, and Penn State colleague Chris House. Fortunately, as Beal peered out of Alvin’s plate-sized portholes during her descent, her claustrophobia quickly gave way to pure, unalloyed exhilaration.

Health Claim Of Probiotics Not Accepted

From The Independent:

£220m-a-year 'dairy shots' industry in disarray following EU scientists' ruling.

Drink this yogurt for a healthier stomach. Thirty million shoppers have swallowed the claims for probiotics as enthusiastically as the sweet fermented milk in the belief that "good bacteria" will defeat "bad bacteria" in epic microscopic battles inside our bodies.

But claims that probiotic ingredients improve health can not be supported, according to an extensive review of scientific research by a team of experts from the European Union.

Word Has It That eReaders Will Open The Next Chapter


From Times Online:

Microsoft and Apple are about to follow the tablet trend.

TRAVELLING between airports has given analyst Jon Peddie lots of time to study tech trends. There was the rise of the mobile, laptops, the iPod, the BlackBerry and the iPhone.

Now Peddie, who runs California-based Jon Peddie Research, sees another change coming: the rise of the eReader.

Laptops are becoming less popular, he reckons, and even netbooks are fading. The new must-have is an eReader.

From The Telegraph:

A huge Siberian volcano destroyed the world's forests 250 million years ago in what scientists say was the worst extinction event the planet has ever witnessed, new research has disclosed.

It rained fire and acid rain for hundreds of thousands of years and killed 90 percent of all life, including plants and vegetation.

An analysis of ancient fungus that thrives in dead wood has given scientists a window into the event.

US Relinquishes Control Of The Internet -- The Guardian

• Icann ends agreement with the US government
• Move will give other countries a prominent internet role

After complaints about American dominance of the internet and growing disquiet in some parts of the world, Washington has said it will relinquish some control over the way the network is run and allow foreign governments more of a say in the future of the system.

Icann – the official body that ultimately controls the development of the internet thanks to its oversight of web addresses such as .com, .net and .org – said today that it was ending its agreement with the US government.

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.)

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.
