First they start paying out 6 to 5 on natural blackjacks, and now this? The little guy gets the short end of the stick once again, as UK researchers say they've developed a computer algorithm that can analyze how Blackjack players manage their chip stack and bet on each hand, sniffing out card counters inside 20 hands of the game.

Quantum Computers Could Tackle Enormous Linear Equations
From Science News:
Trillions of variables may prove no match for envisioned systems.
A new algorithm may give quantum computers a new, practical job: quickly solving monster linear equations. Such problems are at the heart of complex processes such as image and video processing, genetic analyses and even Internet traffic control. The new work, published October 7 in Physical Review Letters, may dramatically expand the range of potential uses for quantum computers.
The new quantum algorithm is “head-smackingly good,” says computer scientist Daniel Spielman of Yale University. “It is both very powerful, and very natural. I read the abstract and said, ‘Why didn’t I think of that?’”

From Popular Science:
What does it take to prep humans for a trip to an asteroid or a martian moon? Starvation? Isolation? Recycling feces for food? NASA's newest astronauts begin a grueling training regimen this fall to find out.
Three test pilots. Two flight surgeons. One molecular biologist. A flight controller, a Pentagon staffer and a CIA intelligence officer. These are the nine people chosen by NASA to be America’s next astronauts. Late this summer they reported to Houston along with two Japanese pilots, a Japanese doctor, a Canadian pilot and a Canadian physicist who will train alongside NASA’s class of 2009. Call them the lucky 14.

Twin Study Reveals Secrets To Looking Younger
From MSNBC:
Sun, smoking, alcohol and stress can all add years to your face.
For years, the similarities between Jeanne and Susan were uncanny. Growing up, the identical twin sisters not only were mirror images of each other, but also shared a bunch of preferences and personality quirks. Even now, living 1,000 miles apart — Jeanne in Ohio, Susan in Florida — “we’ll send identical Christmas cards to our parents and choose the exact same gift wrap,” Jeanne says. But they do have some differences, she adds: “We don’t have the same taste in men or in weather.”

Advance In 'Nano-Agriculture:' Tiny Stuff Has Huge Effect On Plant Growth
Tomato seeds exposed to carbon nanotubes (right) sprouted and grew faster than unexposed seeds (left).
From Science Daily:
Science Daily (Oct. 22, 2009) — With potential adverse health and environmental effects often in the news about nanotechnology, scientists in Arkansas are reporting that carbon nanotubes (CNTs) could have beneficial effects in agriculture. Their study, scheduled for the October issue of ACS Nano, found that tomato seeds exposed to CNTs germinated faster and grew into larger, heavier seedlings than other seeds. That growth-enhancing effect could be a boon for biomass production for plant-based biofuels and other agricultural products, they suggest.

Darwin Lives! Modern Humans Are Still Evolving
From Time Magazine:
Modern Homo sapiens is still evolving. Despite the long-held view that natural selection has ceased to affect humans because almost everybody now lives long enough to have children, a new study of a contemporary Massachusetts population offers evidence of evolution still in action.
A team of scientists led by Yale University evolutionary biologist Stephen Stearns suggests that if the natural selection of fitter traits is no longer driven by survival, perhaps it owes to differences in women's fertility. "Variations in reproductive success still exist among humans, and therefore some traits related to fertility continue to be shaped by natural selection," Stearns says. That is, women who have more children are more likely to pass on certain traits to their progeny.

Naming The Exoplanets
From Technology Review:
The International Astronomical Union is refusing to name the exoplanets. That seems unnecessarily curmudgeonly.
Since 1995, astronomers have found more than 400 planets orbiting other stars. And yet not one of them has a formal name, other than their orginal scientific designation such as MOA-2008-BLG-310-L b, (a sub-Saturnian mass planet recently detected in the Galactic Bulge). How come?

From Christian Science Monitor:
If NASA's Constellation program is going to take astronauts to the moon or Mars, Obama will have to increase its budget, the Augustine report says.
President Obama and Congress face a stark choice on the future of NASA’s human spaceflight program: Either scale back ambitious goals first set out in 2005 or pony up more money to match the ambitions.
That’s the implication of options set out in the final report from the Review of US Human Spaceflight Plans committee, unveiled Thursday afternoon.

Aah... How To Make The Perfect Gravy (And Soy Sauce Is The Secret)
Photo: Roast of the town: Many would prefer to use gravy granules rather than risk ruining a traditional British dinner
From The Daily Mail:
It can make or break a Sunday lunch.
So much so that many will reach for the gravy granules rather than risk ruining a roast.
But scientists have come to the aid of home chefs across the UK with what they believe should be adopted as the 'standard British method' for making gravy.
The Royal Society of Chemistry turned its attention to the subject as part of its Food Year, a series of events to demonstrate the role of chemistry in providing healthy and sustainable food.

How the Internet is Changing the Way We Will Watch TV
From Scientific American:
The Internet stands ready to upend the television viewing experience, but exactly how is a matter of considerable dispute.
It should not be so difficult. In an age when nearly all forms of media are digital, where broadband signals course through the industrial world as surely (and as critically) as electricity and freshwater, it should be possible to sit on one’s couch, push a button or two, and call up to your television any form of video-related entertainment you desire. New-release movies. Last week’s Lost . The first season of Cosmos . Setup should not require an electrical engineering degree, and you should not be forced to sift through 10 incompatible search functions to find the shows you desire.

From Cosmos:
PORTLAND, OREGON: A shift in Jupiter's orbit early in the life of the Solar System dislodged thousands of rocks from the Asteroid Belt, causing them to hit the inner planets, including Earth.
Evidence for this cataclysmic bombardment comes from a reanalysis of lunar rocks brought back by the Apollo astronauts and a careful study of lunar craters, said David Kring, a planetary geologist at the Lunar and Planetary Institute in Houston, Texas.
Kring presented his findings this week at the Geological Society of America's annual meeting in Portland, USA.

Net Neutrality Is 'Fairness Doctrine For The Internet'
From The Hill:
Marsha Blackburn (R-Tenn.) spoke against net neutrality regulations today at an event put on by the Safe Internet Alliance. Representing the songwriters, singers, actors, producers and other entertainers in Memphis and Nashville, she said the creative community does not want the federal government to interfere with how they are able to get content to consumers via the Internet.
"Net neutrality, as I see it, is the fairness doctrine for the Internet," she said. The creators "fully understand what the fairness doctrine would be when it applies to TV or radio. What they do not want is the federal government policing how they deploy their content over the Internet and they want the ISPs to manage their networks and deploy the content however they have agreed on with ISP. They do not want a czar of the Internet to determine when they can deploy their creativity over the Internet. "They do not want a czar to determine what speeds will be available....We are watching the FCC very closely as it relates to that issue."

'Stealth' Wind Turbine Deployed
From the BBC:
A wind turbine blade that absorbs radar signals has been demonstrated at a wind farm in eastern England.
Wind turbines confuse aviation radar signals, making aircraft in wind farms' vicinities difficult to track.
Defence firm Qinetiq and turbine manufacturing firm Vestas are developing "stealth turbines", with radar-absorbing materials and coatings.
The five-year effort may help many wind farm projects that are on hold because of so-called "radar clutter" concerns.

From Discovery News:
Pest-control specialist Gene Scholes even gets bugged by them -- legions of ladybugs lately swarming his rural Missouri home and other stretches across the country, exploiting gaps in door and window seals for cozier climes inside.
Bug experts say the Asian lady beetles, considered harbingers of good luck in many cultures, are making their seasonal appearance in droves in search of warmth for the approaching winter.
The beetles are harmless to humans. That doesn't make them any less annoying for folks like Scholes.

What's The Point Of A Fake 500-Day Mars Mission?
From New Scientist:
The European Space Agency is seeking six volunteers to spend 520 days inside a sealed isolation facility to study the psychological effects of a journey to Mars.
The 2010 Mars-500 "mission" at the Russian Institute of Biomedical Problems in Moscow will simulate a round trip to the Red Planet – albeit shorter than the real thing – and follows a similar 105-day study that ended in July.
But does spending a year and a half locked inside a tin can on Earth tell us anything about how humans might behave on a high-risk interplanetary odyssey? New Scientist investigates.

Scientists Find A Precision Clock Logging the Milliseconds Inside Your Brain
Tick Tock Certain neurons in the striatum and prefrontal cortex fire at certain intervals, which MIT researchers have determined to be an internal clock time-stamping sensory experiences for memory just as a digital camera might time-stamp a photo file.
From Popular Science:
Though we do it without thinking, keeping track of time is integral to the brain's function, keeping our senses and our actions ordered in a chronology that we then recall in the form of memory. But important as it is, researchers have never understood the mechanism by which humans index the happenings of everyday life. Now, two macaque monkeys may have helped MIT researchers solve the time tracking puzzle.
