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.

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.

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.

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.

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.

A MONKEY sits on a bench, wires running from its head and wrist into a small box of electronics. At first the wrist lies limp, but within 10 minutes the monkey begins to flex its muscles and move its hand from side to side. The movements are clumsy, but they are enough to justify a rewarding slug of juice. After all, it shouldn't be able to move its wrist at all.
A nerve connection in the monkey's upper arm had previously been blocked with an anaesthetic that prevented signals travelling from its brain to its wrist, leaving the muscles temporarily paralysed. The monkey was only able to move its arm because the wires and the black box bypassed the broken link.

Now the toxin in bee venom has been harnessed to kill tumor cells by researchers at Washington University School of Medicine in St. Louis. The researchers attached the major component of bee venom to nano-sized spheres that they call nanobees.
In mice, nanobees delivered the bee toxin melittin to tumors while protecting other tissues from the toxin's destructive power. The mice's tumors stopped growing or shrank. The nanobees' effectiveness against cancer in the mice is reported in advance online publication Aug. 10 in the Journal of Clinical Investigation.
