Long-Range Taser Raises Fears Of Shock And Injury
From New Scientist:
INCREASING the distance between yourself and a potentially dangerous assailant is always a good idea - even if your ultimate aim is to render them insensible. That appears to be the thinking behind a Pentagon project, now in its final stages, to perfect a projectile capable of delivering an electric shock to incapacitate a person tens of metres away. It will be fired from a standard 40-millimetre grenade launcher.

Lions Had A Taste For Human Flesh
From Discovery News:
The nightly attacks by two man-eating lions terrified railway workers and brought construction to a halt in one of east Africa's most notorious onslaughts more than a hundred years ago. But the death toll, scientists now say, wasn't as high as previously thought.
Over nine months the two voracious hunters claimed 35 lives -- no small figure, but much less than some accounts of as many as 135 victims.
It was 1898, when laborers from India and local natives building the Uganda Railroad across Kenya became the prey for the pair, a case that has been the subject of numerous accounts and at least three movies.

Inside One Of The World's Largest Data Centers
From CNET:
CHICAGO--On the outside, Microsoft's massive new data center resembles the other buildings in the industrial area.
Even the inside of the building doesn't look like that much. The ground floor looks like a large indoor parking lot filled with a few parked trailers.
It's what's inside those trailers, though, that is the key to Microsoft's cloud-computing efforts. Each of the shipping containers in the Chicago data center houses anywhere from 1,800 to 2,500 servers, each of which can be serving up e-mail, managing instant messages, or running applications for Microsoft's soon-to-be-launched cloud-based operating system--Windows Azure.
Web Could Run Out Of Addresses Next Year, Warn Web Experts
From The Telegraph:
Businesses urgently need to upgrade to IPv6, a new version of the internet's addressing protocol that will hugely increase the number of available addresses.
A survey, conducted by the European Commission, found that few companies are prepared for the switch from the current naming protocol, IPv4, to the new regime, IPv6. Web experts have warned that we could run out of internet addresses within the next two years unless more companies migrate to the new platform.

'Breaking' Curveballs Are Just an Illusion
From Live Science:
The answer to the question of whose curveball breaks harder — that of the Yankees' A.J. Burnett or the Phillies' Cole Hamels — may be neither. Zhong-Lin Lu, professor of cognitive neuroscience at USC, along with colleagues from USC and American University, developed a simple visual demo that suggests a curveball's break is, at least in part, a trick of the eye. Their demo won the Best Visual Illusion of the Year prize at the Vision Sciences meeting earlier this year. Try it here. A related press release is here. The curveball's effect is due to batters being forced to switch between peripheral vision and central vision during a swing. For more on the research, see Lu's Web page.

'Fear Detector' Being Developed That Will Be Able To Sniff Out Terrorists
From The Daily Mail:
A device that smells human fear is being developed by British scientists and could soon be sniffing out anxious terrorists.
The technology relies on recognising a pheromone - or scent signal - produced in sweat when a person is scared.
Researchers hope the 'fear detector' will make it possible to identify individuals at check points who are up to no good.
Terrorists with murder in mind, drug smugglers, or criminals on the run are likely to be very fearful of being discovered.

Getting Beyond Petroleum Won't Be Easy
From Technology Review:
Transportation defines our civilization. Where we live and work, the structure of our cities, the flow of global commerce--all have been shaped by transportation technologies. But modern transportation's reliance on fossil fuels cannot be sustained. Passenger planes, trains, and automobiles were responsible for nearly four billion tons of carbon dioxide emissions in 2005--about 14 percent of the carbon dioxide emitted globally that year. If we continue to rely almost exclusively on petroleum to power these vehicles, they will be responsible for 11 billion to 18 billion tons of carbon dioxide emissions in 2050. That's because developing nations--which are home to 82 percent of the world's population and will be responsible for 98 percent of population growth in coming years--are on the verge of mass motorization. Auto ownership in the developing world is growing at a rate of 30 percent per year (see "Cleaner Vehicles by the Million").

Stealth-Mode Wind Turbines
From Technology Review:
Coatings and composites ease the air-traffic worries dogging wind power.
Last month Danish wind turbine company Vestas and U.K. defense contractor QinetiQ demonstrated the first "stealth" wind-turbine blade--their solution to the aviation radar interference problem holding up the installation of gigawatts-worth of proposed wind farms worldwide. Vestas composites specialist Steve Appleton says the firm is eager to test a complete stealth turbine and begin limited production by the end of 2010. "Clearly this technology, if proven fully and then adopted by Vestas, would give us a competitive advantage," says Appleton.

Recipe for Mass Extinction: Add Algae and Stir Controversy
From Live Science:
Mass extinctions that wiped entire species off the face of the Earth in a relative blink of the eye are often blamed on catastrophic occurrences, such as an asteroid crash or large volcanic eruption. But a new hypothesis points to a different culprit: lowly algae.
In the past 540 million years, five massive extinctions are thought to have killed off, in each case, some 50 percent to 90 percent of animal species. A new study suggests that toxins from algae played a major role in all five extinctions, including the most recent and most well-known – the death of the dinosaurs 65 million years ago. The idea was presented at the annual Geological Society of America meeting Oct. 19.

Sleep Deprivation Cut Mental Function
From Future Pundit:
The brain downshifts to simpler ways of processing information when lacking sleep.
Read more ....Westchester, Ill. —A study in the Nov.1 issue of the journal Sleep shows that sleep deprivation causes some people to shift from a more automatic, implicit process of information categorization (information-integration) to a more controlled, explicit process (rule-based). This use of rule-based strategies in a task in which information-integration strategies are optimal can lead to potentially devastating errors when quick and accurate categorization is fundamental to survival.

Why Three Buses Come At Once, And How To Avoid It
From New Scientist:
Anyone who has waited for a bus knows the routine: you wait far longer than you should, then three come along at once. The problem, called "platooning", plagues buses, trains and even elevators.
Now systems complexity researchers Carlos Gershenson and Luis Pineda of the National Autonomous University of Mexico have devised a mathematical model that shows how the problem might be prevented: transport managers need to get a little meaner about boarding times, and passengers should realise that jumping on the first train or bus that arrives won't always help them reach a destination faster.

From Popular Science:
One of the most difficult aspects of science is conceptualizing some of the unbelievably large, (and unimaginably small) numbers that routinely pop up. The Universe is 5.5 x 10^23 miles across. A human hair is about 7 x 10^-4 inches across. Hard to imagine how things like cells, proteins and atoms all relate to one another. Now, at least for the very small things, the University of Utah has developed a fun little Flash graphic to make sense of all of it.

Clinical Immortality And Space Settlement
From The Space Review:
There was a recent article in the New York Times, “Three Score and Ten”, which was inspired by a Lancet paper that predicted the median life expectancy for babies born in America in 2007 is greater than or equal to 104. In 3000 BC, it was 24 and stayed there almost until the industrial revolution. In 1850, it was 38. In 1909, it was 50. In 1959, it was 67. Current demographics indicate it’s only 78. The extra 26 years that Lancet predicts comes from anticipated future improvements in reducing death rates (morbidity).

Rest Easy: Retirement (and Money) Can Improve Sleep
From Live Science:
It's no secret the stress of work can keep you up at nights. Now research shows that retirement can spur less fitful sleep, at least for people who are financially stable.
The prevalence of sleep disturbances among 14,714 study participants in France — all of whom had pensions that continued to pay 80 percent of their salaries — fell from 24.2 percent in the last year before retirement to 17.8 percent in the first year after retiring.
The finding may not apply to retirees who lack financial stability, however.

Russia Becomes The World's Taxicab To Space
From Christian Science Monitor:
Though its program is nothing like it once was, the country uses its fleet of rockets to ferry tourists and satellites into orbit.
Moscow - For better or mirth, it has become one of those indelible images from space: Canadian circus billionaire Guy Laliberté floating around the International Space Station wearing a red clown nose.
The stunt earlier this month by the founder of Cirque du Soleil, who once performed as a fire breather, was intended to provide a moment of levity for his wife and children during a video linkup. But it also served a more serious purpose: to draw attention to the crusade for which he paid $35 million to journey into orbit – the need for clean water on Earth.

Heaven Can Wait
From Newsweek:
A new book promises incontrovertible proof of the afterlife. That's cold comfort to those of us left behind.
On a spring day last year, three months after the death of my younger son, Max, I opened my front door and saw a butterfly resting on the steps—an Eastern tiger swallowtail, I later determined, a species native to the Northeast but not one I remembered seeing before in the middle of Brooklyn. The date stuck in my mind because, as it happens, it was also my birthday. The butterfly, with its otherworldly beauty and silence, is, of course, a common metaphor for the soul. Its emergence from entombment as a chrysalis may have inspired ideas about human resurrection.

Rocket Men
From Newsweek:
Politicians won't get us back into the space race, but novelists just might.
Six months ago, President Obama asked a team of academics, astronauts, and aerospace executives to give him options for the future of the space program. Those options, as described in the Augustine Committee's just-released final report, must have sent a little thrill up our Spock-loving nerd in chief's leg: setting up a lunar base, flying to a Martian moon, etc. There's just one catch: NASA doesn't have the resources it needs to pursue these plans. Exciting proposals for voyages to alien moons aside, the report's attention to dollars and cents makes it a cosmic buzzkill.

America’s Electronic Waste Is Polluting the Globe
It seems that every day brings a new electronic gadget to the market, whether it’s a smart phone, an electronic reader, a laptop the size and weight of a magazine, or a television the size of a wall. But each advance adds to the world’s electronic waste, which is the fastest-growing component of solid waste. Much of the electronic refuse ends up in developing countries, where workers strip down the gadgets to get at the copper and other valuable metals inside, often exposing themselves to toxins in the process. Now, scientists are calling for federal regulations in the United States to stem the tide.
