From Popsci.com:

A new drug could foil any outbreak.

Before swine flu swept through the U.S., the virus had bounced around South America undetected for years. The H1N1 strain caught scientists by surprise, and without a vaccine. But a few weeks before the first North American case popped up, researchers successfully tested a therapy that could knock out almost any flu, and possibly any virus.

Beyond The Moon: A Chat With Buzz Aldrin

Preparing for an Apollo 11 Countdown Test: NASA

From Popsci.com:

The 79-year-old astronaut says: Enough about the moon; let's go to Mars.

It's been 40 years since Neil Armstrong and Edwin "Buzz" Aldrin landed the Apollo 11 lunar module in the Sea of Tranquility. Aldrin, now 79 years old, recalls that fateful day with clarity. Alarms were sounding inside the space capsule during their speedy descent, and even down to the last seconds, the astronauts were uncertain whether they would need to abort the landing. Millions of Earthlings watched on television as the Eagle touched down.

For 13 Astronauts, A Day Off In Space

International Space Station

From Yahoo News/Space.com:

The 13 people living on the International Space Station took some hard-earned time off Saturday, a welcome relief after a hectic week of orbital construction.

It's a rare rest day for the station's six-man crew and seven visiting astronauts from the space shuttle Endeavour, who have plowed through a week packed with four spacewalks and robotic arm work to upgrade the orbiting laboratory with new batteries, spare parts and - their crown jewel - a brand new Japanese porch, complete with experiments.

"On a very long mission like this, it's really important that they get some time to recuperate and recover and really just enjoy being on orbit as the first 13-person crew," space station flight director Holly Ridings told reporters late Friday.

Jupiter: Our Cosmic Protector? -- The New York Times

Jupiter took a bullet for us last weekend.

An object, probably a comet that nobody saw coming, plowed into the giant planet’s colorful cloud tops sometime Sunday, splashing up debris and leaving a black eye the size of the Pacific Ocean. This was the second time in 15 years that this had happened. The whole world was watching when Comet Shoemaker-Levy 9 fell apart and its pieces crashed into Jupiter in 1994, leaving Earth-size marks that persisted up to a year.

Europe's Mars Rover Slips To 2018

From The BBC:

Europe's flagship robotic rover mission to Mars now looks certain to leave Earth in 2018, two years later than recently proposed, the BBC understands.

The ExoMars vehicle is intended to search the Red Planet for signs of past or present life.

The delay is the third for the mission originally planned to launch in 2011.

While the switch will disappoint many people, officials say the change will open up a greatly expanded programme of exploration at the Red Planet.

Strong Evidence That Cloud Changes May Exacerbate Global Warming

From Science Daily:

ScienceDaily (July 24, 2009) — The role of clouds in climate change has been a major question for decades. As the earth warms under increasing greenhouse gases, it is not known whether clouds will dissipate, letting in more of the sun's heat energy and making the earth warm even faster, or whether cloud cover will increase, blocking the Sun's rays and actually slowing down global warming.

In a study published in the July 24 issue of Science, researchers Amy Clement and Robert Burgman from the University of Miami's Rosenstiel School of Marine and Atmospheric Science and Joel Norris from Scripps Institution of Oceanography at UC San Diego begin to unravel this mystery. Using observational data collected over the last 50 years and complex climate models, the team has established that low-level stratiform clouds appear to dissipate as the ocean warms, indicating that changes in these clouds may enhance the warming of the planet.

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.

"Yes, we are still going," said James Williams, a JPL scientist involved with the experiment, in an e-mail interview.

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.

From National Geographic:

Attacking from nests as big as pickup-truck beds, invasive western yellowjacket wasps in Hawaii are munching their way through an "astonishing diversity" of creatures, from caterpillars to pheasants, a new study says.

Adult yellowjackets consume only nectar. But they kill or scavenge prey to deliver needed protein to their growing broods.

From The Telegraph:

Nasa has found a monster black hole 100 million times the mass of the Sun feeding off gas, dust and stars at the centre of a galaxy 50 million light-years away.

The star-ringed black hole forms the eye of a galaxy called NGC-1097 which was photographed by the US space agency's Spitzer Space Telescope in California.

A black hole is a region of space in which the gravitational pull is so powerful that nothing, including whole planets, can escape being sucked in if they come within its reach.

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.

Money Relieves Pain

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

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.
