Unraveling The Brain's Secrets: Humility Required

From Scientific American:

In early October, the Singularity Summit took place on Manhattan’s Upper East Side, a conference that highlighted the prospects for abolishing the ravages of aging and disease. So you’ll be able to live forever, unless you get hit by a truck.

Living forever is mainly about preserving brain function. That’s why the cryonicists—the ones who freeze themselves until some hypothetical medical miracle emerges to revive them—often just put the part above the neck into deep storage. The head in the cooler, it is assumed, retains the operating system and all of the applications software needed to resurrect the former self, even if it is ported to some new, cybernetic body. Less real estate and a lower electricity bill means a reduced rate at the cryo farm until you are brought back from the “legally dead.” In essence, bleacher seats for the Singularity.

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

What keeps a woman looking young?
A study of identical twins reveals some surprising answers.

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.

From The CNN:

(CNN) -- Hidden under a quaint resort 60 miles northeast of Fairbanks, Alaska, lies a treasure trove of potential energy that's free and available 24/7.

Alaskan entrepreneur Bernie Karl has pioneered modern technology to tap into one of Earth's oldest energy resources: hot water.

Karl, 56, likes to call himself an "imagineer."

Using imagination to fuel his engineering ambitions, this tenacious thinker and self-starter has figured out a way to generate electricity using water that's the temperature of a cup of coffee -- about 165 degrees Fahrenheit.

Darwin Lives! Modern Humans Are Still Evolving

A. Green / Corbis

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.

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.

What's The Point Of A Fake 500-Day Mars Mission?

Mars

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.
