How Science Can Create Millions of New Jobs
From Business Week:
Reigniting basic research can repair the broken U.S. business model and put Americans back to work .
Name an industry that can produce 1 million new, high-paying jobs over the next three years. You can't, because there isn't one. And that's the problem.
America needs good jobs, soon. We need 6.7 million just to replace losses from the current recession, then an additional 10 million to keep up with population growth and to spark demand over the next decade. In the 1990s the U.S. economy created a net 22 million jobs, or 2.2 million a year. But from 2000 to the end of 2007, the rate plunged to 900,000 a year. The pipeline is dry because the U.S. business model is broken. Our growth engine has run out of a key fuel—basic research.

Future Robot Soldiers?
The Exoskeleton: Extreme Technological Innovation -- Raytheon
Raytheon Company’s research facility in Salt Lake City, Utah, is developing a robotic suit for the soldier of tomorrow. The exoskeleton is essentially a wearable robot that amplifies its wearer’s strength, endurance and agility. Reminiscent of super heroes depicted in comic books and Hollywood movies, the bleeding edge technology effectively blurs the lines between science fiction and reality. So much so, that Popular Science magazine recently likened Raytheon’s exoskeleton to the “Iron Man”® depicted in the blockbuster movie of the same name.

Studying Ancient Man To Learn To Prevent Disease
iStockphotoFrom The Philadelphia Inquirer:
Health care as we know it didn't exist 3,000 years ago. But along the Georgia coast, the Pacific Northwest, and coastal Brazil, people grew tall and strong and lived relatively free of disease. They ate game, fish, shellfish, and wild plants.
But as corn farming spread through various regions of the Americas, people got shorter. Many became prone to anemia and began dying of tuberculosis and other infectious diseases.

From Science Daily:
ScienceDaily (Sep. 1, 2009) — The ability to digest the milk sugar lactose first evolved in dairy farming communities in central Europe, not in more northern groups as was previously thought, finds a new study led by UCL (University College London) scientists published in the journal PLoS Computational Biology.
The genetic change that enabled early Europeans to drink milk without getting sick has been mapped to dairying farmers who lived around 7,500 years ago in a region between the central Balkans and central Europe.

Dogs Descended From Wolf Pack On Yangtze River
From The Telegraph:
Today's dogs are all descended from a pack of wolves tamed 16,000 years ago on the shores of the Yangtze river, according to new research.
It was previously known that the birthplace of the dog was eastern Asia but historians were not able to be more precise than that.
However, now researchers have made a number of new discoveries about the history of man's best friend - including that the dog appeared about 16,000 years ago south of the Yangtze river in China.

What Happens When an Astronaut Sneezes?
No kidding! This CDC photograph captured a sneeze in progress, revealing the plume of salivary droplets as they are expelled in a large cone-shaped array from this man's open mouth. The flu virus can spread in this manner and survive long enough on a doorknob or countertop to infect another person. It dramatically illustrating the reason you should cover your mouth when sneezing or coughing to protect others from germ exposure, health officials say. It’s also why you need to wash your hands a lot, on the assumptions others don’t always cover their sneezes. Credit: CDC/James Gathany .From Live Science:
Best to do the sneezing inside a shuttle or the space station, not on a spacewalk, when it can get real messy, with goo sprayed all over the inside of the helmet's "windshield."
Lately astronauts have been complaining about stuffy heads up there on the International Space Station. NASA doesn't think they have colds, though. Rather, the effects have more to do with pockets of carbon dioxide generated when they gather in groups, space station flight controller Heather Rarick said.
Space Mission To Mercury: How An Ion Engine Works
Photo courtesy NASAThis image of a xenon ion engine, photographed through a port of the vacuum chamber where it was being tested at NASA's Jet Propulsion Laboratory, shows the faint blue glow of charged atoms being emitted from the engine. The ion propulsion engine is the first non-chemical propulsion to be used as the primary means of propelling a spacecraft.
From The Telegraph:
The solar electric propulsion systems – or ion engines - which will power the next generation of spacecraft to Mercury and beyond are ten times more efficient than conventional rocket engines.
In an ion engine the gas xenon is pumped through a chamber where xenon atoms are stripped of an electron, becoming electrically charged ions, and drift towards two grids a millimetre apart.
The grids are fed with two thousand volts – in space this power will come from paper-thin solar panels spanning 26m. As the ions pass through the electrified grids they accelerate to up to 50km a second and shoot from the rear in a parallel beam.

First Baby Born From New Egg-Screening Technique
From Breitbart/AFP:Meet Oliver, the first baby in the world born using a new egg-screening technique that could double the odds of an implanted embryo taking hold in the womb, unveiled by British experts on Wednesday.
Baby Oliver was born in Britain to a 41-year-old woman after 13 failed attempts at in vitro fertilisation (IVF).
The new technique, called array comparative genomic hybridisation (CGH), makes it possible to ensure eggs have a normal number of chromosomes, boosting the likelihood of a successful pregnancy.

Great Ball Of Fire? No, Just A 'Sun Dog' Scampering Across The Sky
Blazing light: The flash was photographed by Matthew Pinlessnear his home in Cheltenham, Gloucestershire
From The Daily Mail:
Matthew Pinless was sure that the streak of light he spotted in the sky while walking was more likely to be a meteor than a UFO.
In fact it was neither. The blazing ball hanging above a residential street in Cheltenham, Gloucestershire, is thought to be a ‘sun dog’.
The phenomenon occurs when sunlight is refracted by hexagonal-shaped ice crystals in high and cirrus clouds - and is quite common, experts say.

First Spacewalk Complete
From Red Orbit:
The first spacewalk of the STS-128 mission came off without a hitch on Tuesday, as spacewalkers Danny Olivas and Nicole Stott completed all the tasks on their to-do list.
Olivas and Stott left the International Space Station at 4:49 p.m. Tuesday, and spent the next 6 hours and 35 minutes outside, working to get cargo that space shuttle Discovery will bring home ready for its return. They started with a depleted ammonia tank assembly on the P1, or port 1, segment of the station’s truss, getting it out of the way in preparation for the installation of a new tank to be installed on Thursday, during the mission’s second spacewalk. The ammonia in the tanks is used to cool the station and expel the heat generated by its residents and systems.

Finding Smells That Repel
Michael C. Witte From The Wall Street Journal:
If you're one of those people whom mosquitoes tend to favor, maybe it's because you aren't sufficiently stressed-out.
Insects have very keen powers of smell that direct them to their targets. But for researchers trying to figure out what attracts or repels the pests, sorting through the 300 to 400 distinct chemical odors that the human body produces has proved daunting.

Keeping Genes Out Of Terrorists' Hands

Gene-synthesis industry at odds over how to screen DNA orders.
A standards war is brewing in the gene-synthesis industry. At stake is the way that the industry screens orders for hazardous toxins and genes, such as pieces of deadly viruses and bacteria. Two competing groups of companies are now proposing different sets of screening standards, and the results could be crucial for global biosecurity.
"If you have a company that persists with a lower standard, you can drag the industry down to a lower level," says lawyer Stephen Maurer of the University of California, Berkeley, who is studying how the industry is developing responsible practices. "Now we have a standards war that is a race to the bottom."

Global Warming And The Sun -- A Commentary
From L.A. Times:
Recent studies seem to show that there's more to climate change than we know.
Assuming there are no sunspots today, a 96-year record will have been broken: 53 days without any solar blemishes, giant magnetic disruptions on the sun's surface that cause solar flares. That would be the fourth-longest stretch of stellar solar complexion since 1849. Wait, it gets even more exciting.
During what scientist call the Maunder Minimum -- a period of solar inactivity from 1645 to 1715 -- the world experienced the worst of the cold streak dubbed the Little Ice Age. At Christmastime, Londoners ice skated on the Thames, and New Yorkers (then New Amsterdamers) sometimes walked over the Hudson from Manhattan to Staten Island.
