From Live Science:

The terrain of the North Slope of Alaska is not steep, but Andrew Jacobson still has difficulty as he hikes along the spongy tundra, which is riddled with rocks and masks multitudes of mosquitoes.

Jacobson, a professor of earth and planetary sciences at Northwestern University, extracts soil and water samples in search of clues to one of global warming's biggest ticking time bombs: the melting of permafrost.

Permafrost, or frozen ground, covers approximately 20 to 25 percent of the land-surface area in the northern hemisphere, and is estimated to contain up to 1,600 gigatons of carbon, primarily in the form of organic matter. (One gigaton is equivalent to one billion tons.)

Traffic Hydrocarbons Linked To Lower IQs In Kids

From Science News:

Prenatal exposures to common air pollutants correlate with drop in intelligence scores.

Here’s a dirty little secret about polluted urban air: It can shave almost 5 points off of a young child’s IQ, a new report suggests.

That’s no small loss, says Kimberly Gray, whose federal agency cofinanced the study, to appear in the August Pediatrics.

Normally, baseline environmental exposures to a pollutant yield at most a subtle change — one that is hard to detect and with impacts that are hard to gauge, says Gray, of the National Institute of Environmental Health Sciences in Research Triangle Park, N.C. But the new study shows that children heavily exposed in the womb to common combustion pollutants known as polycyclic aromatic hydrocarbons had, by kindergarten age, an IQ some 4.5 points lower than that of kids with minimal fetal exposures.

Apollo 11 Experiment Still Going After 40 Years

Lunar Laser Ranging Experiment

From Yahoo News/Space:

The Apollo 11 astronauts returned from the moon 40 years ago today, but they left behind more than footprints. An experiment they placed on the moon's surface is still running to this day.

The Lunar Laser Ranging Experiment is the only moon investigation to continuously operate since the Apollo 11 mission. The experiment studies the Earth-Moon system and beams the data to labs around the world, including NASA's Jet Propulsion Laboratory (JPL) in Pasadena, Calif.

Is the Sun Missing Its Spots?

SUN GAZING These photos show sunspots near solar maximum on July 19, 2000, and near solar minimum on March 18, 2009. Some global warming skeptics speculate that the Sun may be on the verge of an extended slumber. NASA

From The New York Times:

The Sun is still blank (mostly).

Ever since Samuel Heinrich Schwabe, a German astronomer, first noted in 1843 that sunspots burgeon and wane over a roughly 11-year cycle, scientists have carefully watched the Sun’s activity. In the latest lull, the Sun should have reached its calmest, least pockmarked state last fall.

Indeed, last year marked the blankest year of the Sun in the last half-century — 266 days with not a single sunspot visible from Earth. Then, in the first four months of 2009, the Sun became even more blank, the pace of sunspots slowing more.

What NASA's Return To The Moon May Look Like

To explore the lunar surface, NASA envisions a pressurised rover that will act as a mobile habitat, allowing astronauts to explore the lunar surface for weeks at a time without returning to their base. If supply depots are scattered along the way, these rovers could potentially have a range of hundreds of kilometres. (Image: Regan Geeseman)

From New Scientist:

The Apollo era may have ended as funding fizzled, and the programme's astronauts may be bigger fans of Mars, but the hope of returning to the moon never really went away.

Twenty years ago, on the 20th anniversary of the Apollo 11 moon landing, then-President George H. W. Bush proposed that the US build a base on the moon and send an expedition to Mars. The call fell flat with Congress, which never provided the funding to back up the plan.

But a decade and a half later, his son, President George W. Bush, articulated a similar vision with a clear deadline – an aim to return humans to the moon by 2020, as a stepping-stone on the way to Mars.

From Live Science:

Money dulls physical pain and eases the sting of social rejection, new research shows.

Through six experiments, psychologists and a marketing professor probed the power of money as a proxy for social acceptance. Among their results, they found that merely touching bills or thinking about expenses paid affected the participants both physically and emotionally.

Because it affects pain, money may be a clue to how the brain evolved to process social interactions, the researchers wrote in a paper published in the June edition of the journal Psychological Science.

CSI Stone Age: Did Humans Kill Neanderthals?

A painting imagines the world of Neanderthal men

From Time Magazine:

It is one of the world's oldest cold cases. Sometime between 50,000 and 75,000 years ago, a Neanderthal male known to scientists as Shanidar 3 received a wound to his torso, limped back to his cave in what is now Iraq and died several weeks later. When his skeleton was pieced together in the late 1950s and early '60s, scientists were stumped by a rib wound that almost surely killed him, hypothesizing that it could have been caused by a hunting accident or even a fellow Neanderthal. New research suggests that Shanidar 3 may have had a more familiar killer: a human being.

How To Use Your iMac As A Second Screen

The 17in iMac on display at Macworld 2002 in New York.
(Photograph by Mario Tama/Getty Images)

From Popular Mechanics:

Can you use your iMac's built-in monitor as a second screen for another computer? The answer is yes. Here's how.

Q:
My iMac has a built-in monitor. Is there a way of using this as a second screen for another computer?

A:
When it comes to screen space, you can never go overboard. Large monitor and multiscreen set-ups make it easy to multitask, and have been shown by a number of studies to boost productivity. It’s a shame, then, that Apple doesn’t build video input jacks into its iMacs—these all-in-one computers have a built-in monitor, and it’d be nice to be able to use it with other systems. This would be particularly useful for laptop users looking for a way to expand screen space when they aren’t on the road.

But even without an input jack, you can still put an iMac to work as an external monitor for another com­puter. You’ll need a program called ScreenRecycler, which employs what is called the VNC, or Virtual Network Computing, protocol. VNC is usually used as a way to allow one computer to remotely access and control ­another, but ScreenRecycler uses it to turn the second computer into an adjunct monitor. Note, though, that while the second screen can come from any type of computer (even a laptop), the com­puter you’re working on has to be a Mac.

Eclipse Of The Century Live Online Tonight

From Wired Science:

The century’s most dramatic solar eclipse will be visible along a narrow swath of Asia and the Pacific Ocean later today. And, thanks to some University of North Dakota researchers, it’ll be visible on the internet, too. The live webcast begins at 5:15 p.m. Pacific time.

The eclipse will last six minutes and 39 seconds, which is near the theoretical maximum duration for a solar eclipse of seven minutes and 31 seconds. For everyone except Ray Kurzweil and the other singulatarians, this will be the longest eclipse of our lifetimes. The Earth won’t see an eclipse this long until June 13, 2132.

Evolutionary Origins of Your Right and Left Brain

In the human brain the left hemisphere controls language, the dexterity of the right hand, the ability to classify, and routine behavior in general. The right hemisphere specializes in reacting to emergencies, organizing items spatially, recognizing faces and processing emotions.

From Scientific American:

The division of labor by the two cerebral hemispheres—once thought to be uniquely human—predates us by half a billion years. Speech, right-handedness, facial recognition and the processing of spatial relations can be traced to brain asymmetries in early vertebrates

The left hemisphere of the human brain controls language, arguably our greatest mental attribute. It also controls the remarkable dexterity of the human right hand. The right hemisphere is dominant in the control of, among other things, our sense of how objects interrelate in space. Forty years ago the broad scientific consensus held that, in addition to language, right-handedness and the specialization of just one side of the brain for processing spatial relations occur in humans alone. Other animals, it was thought, have no hemispheric specializations of any kind.

From Reuters:

HONG KONG (Reuters) - Dust clouds generated by a huge dust storm in China's Taklimakan desert in 2007 made more than one full circle around the globe in just 13 days, a Japanese study using a NASA satellite has found.

When the cloud reached the Pacific Ocean the second time, it descended and deposited some of its dust into the sea, showing how a natural phenomenon can impact the environment far away.

"Asian dust is usually deposited near the Yellow Sea, around the Japan area, while Sahara dust ends up around the Atlantic Ocean and coast of Africa," said Itsushi Uno of Kyushu University's Research Institute for Applied Mechanics.

From Science Daily:

ScienceDaily (July 20, 2009) — The potential for a huge Pacific Ocean tsunami on the West Coast of America may be greater than previously thought, according to a new study of geological evidence along the Gulf of Alaska coast.

The new research suggests that future tsunamis could reach a scale far beyond that suffered in the tsunami generated by the great 1964 Alaskan earthquake. Official figures put the number of deaths caused by the earthquake at around 130: 114 in Alaska and 16 in Oregon and California. The tsunami killed 35 people directly and caused extensive damage in Alaska, British Columbia, and the US Pacific region*.

From Live Science:

Space rocks that slammed into the glaciers of eastern Canada some 12,900 years ago likely helped wiped out mega-animals like woolly mammoths and possibly the continent's first human inhabitants called the Clovis people, according to a new study that adds to evidence that a trio of factors were involved.

The new evidence comes from recently discovered nano-sized diamonds, which researchers say are the strongest clues to date for an argument that could explain the region's die-off during the late Pleistocene epoch.

Five Human Achievements That Could Top Walking on the Moon

Free Fusion Energy?: The National Ignition Facility Target Room

From Popsci.com:

Forty years after Apollo 11, a look forward at the world-changing discoveries that could match--or even top--humankind's first steps on the moon.

Possibly the single most influential event in the public's interest in science and technology (not to mention one of humankind’s greatest adventures), the Apollo 11 mission touched the collective dreams of millions, while pushing science and technology swiftly forward at an unprecedented pace.

But in the decades since man first walked on the moon, science has advanced so rapidly that technology which even a few years ago might have been considered magic has become commonplace. Even so, it would be naïve to assume that Apollo 11 ever represented science and technology’s pinnacle, and that nothing forthcoming will similarly explode the world’s collective dreams and perceptions of what it means to be human.
