Fresh Impact Risks For Asteroid 'Poster Child'
From New Scientist:
The chances of the asteroid Apophis hitting Earth in 2036 are lower than we thought. But those worried about deep impacts should add a new entry to their calendar: 2068.
When Apophis was first spotted in 2004, the 250-metre-wide rock was briefly estimated to have a 2.7 per cent chance of hitting Earth in 2029. Further observations quickly showed that it will miss Earth that year – but should it pass through a 600-metre-wide "keyhole" in space, it will return to hit Earth in 2036.

From Science Daily:
Science Daily (Oct. 6, 2009) — New research from the University of Southampton has demonstrated that it is possible for communication from person to person through the power of thought -- with the help of electrodes, a computer and Internet connection.
Brain-Computer Interfacing (BCI) can be used for capturing brain signals and translating them into commands that allow humans to control (just by thinking) devices such as computers, robots, rehabilitation technology and virtual reality environments.

Proposal Would Turn San Francisco Bridge Into A City
The Bay Line, a proposal for modular housing and other structures bolted to the now-unused San Francisco Bay Bridge. Design by Ronald Rael and Virginia San Fratello
From Live Science:
San Francisco's Bay Bridge is being redone; a large portion of the bridge will remain unused, but in good shape. What can city planners do with this unique, unused space?
Science fiction writer William Gibson thought about the Bay Bridge in his 1993 novel Virtual Light:
"[Chevette] looked up, just as she whipped between the first of the slabs, and the bridge seemed to look down at her, its eyes all torches and neon. She'd seen pictures of what it had looked like, before, when they drove cars back and forth on it all day, but she'd never quite believed them. The bridge was what it was, and somehow always had been. Refuge, weirdness, where she slept, home to many and all their dreams."

In The Future, All Our Pop Idols Will Be Machines
Direction of NASA’s Future At An Impasse
From Wired Science:
The committee charged with rethinking American human spaceflight is done thinking, but it’s still unclear what the future of NASA’s astronaut corps might be, and some nagging issues have yet to be resolved.
The U.S. Human Space Flight Plans Committee — known informally as the Augustine commission, after its head Norm Augustine, former CEO of Lockheed Martin — held its last teleconference today. The ball, or hot potato, will soon be in the Obama administration’s court when the group formally presents its alternatives to the Office for Science and Technology Policy.

Fossils Suggest An Ancient CO2-Climate Link
From Time Magazine:
Some of the best evidence linking rising carbon dioxide levels to a warmer world comes from the coldest places on earth. Samples of ancient air extracted from deep inside the Antarctic and Greenland ice caps make it clear that CO2 is scarce in the atmosphere during ice ages and relatively abundant during warmer interglacial periods — like the one we're in now.
The relationship between CO2 and climate is clear going back about 800,000 years. Before that, however, it gets murkier. That's largely because ice and air that old haven't yet been found. So scientists rely instead on indirect measurements — and these have led to a climate mystery: some episodes of past warming, including a planetary heat wave about 15 million years ago and another about 3.5 million years ago, seem to have happened without a rise in CO2. No one quite understands why. Maybe other greenhouse gases were the cause — methane, for example. Or maybe it had to do with changes in ocean circulation.

Europa, Jupiter's Moon, Could Support Complex Life
Europa, pictured above, may have enough oxygen to support complex, animal-like organisms, according to a new study. NASA
From Discovery:
Jupiter's moon Europa should have enough oxygen-rich water to support not only simple micro-organisms but also complex life, according to a University of Arizona researcher who studies ice flows on the frozen moon.
Judging by how quickly Europa's surface ice is replenished, Richard Greenberg estimates that enough oxygen reaches the subterranean ocean to sustain "macrofauna" -- more complex, animal-like organisms.

The Fatal Consequences Of Counterfeit Drugs
From Smithsonian Magazine:
In Southeast Asia, forensic investigators using cutting-edge tools are helping stanch the deadly trade in fake anti-malaria drugs
In Battambang, Cambodia, a western province full of poor farmers barely managing to grow enough rice to live on, the top government official charged with fighting malaria is Ouk Vichea. His job—contending with as many as 10,000 malaria cases a year in an area twice as large as Delaware—is made even more challenging by ruthless, increasingly sophisticated criminals, whose handiwork Ouk Vichea was about to demonstrate.

From The Reuters:
ROTTERDAM, Netherlands (Reuters) - Microsoft has no plans to develop a digital book reader to compete with the fast-growing popularity of Amazon's Kindle or a device that rival Apple is reportedly developing.
Chief Executive Steve Ballmer said Microsoft had no need for its own e-reader, since it already supplies the software that runs the most popular device for electronic reading.
"We have a device for reading. It's the most popular device in the world. It's the PC," Ballmer said on Thursday on the sidelines of television show recording at Erasmus University in the Netherlands.

Why NASA Barred Women Astronauts
From New Scientist:
About 50 years ago, as the US worked towards putting its first men in space, a few people thought there was another option: women in space. The facts about this episode have been somewhat obscured by the myths that have grown up around it.
In 1960-61, a small group of female pilots went through many of the same medical tests as the Mercury astronauts, and scored very well on them – in fact, better than some of the astronauts did. A new study that presents the first published results of their physiological tests shows that much is fact.

Twitter On The Verge Of Big Search Deals?
From CNET:
Are Microsoft and Google hoping to get into Twitter's treasure trove of real-time information? Yes, says Kara Swisher of AllThingsD, citing sources who indicate that the two companies are separately in talks with Twitter about data licensing deals.
This would involve the exchange of several million dollars plus a revenue-share to "compensate Twitter for its huge and potentially valuable trove of real-time and content-sharing information, generated from the data stream of billions of tweets of its 54 million monthly users," Swisher wrote.

England Footballers Miss Penalties As They See The Goal As Smaller Than Their Rivals
From The Telegraph:
England footballers have been handed another excuse for why they keep missing penalties – they perceive the goalmouth as narrower than their successful rivals, claim scientists.
Researchers have discovered that confident sportsman who always score actually see a larger target in their mind's eye.
Conversely those who miss all the time come to see it as smaller.
Jessica Witt, assistant professor of psychological sciences at Purdue University in Indiana, found sportsmen who had been previously successful were more likely to see the goal as wider because their perception had been altered by their success.
