Birth Control Pill for Men? Scientists Find a Hormonal on-and-Off Switch For Male Fertility
From Science Daily:
Science Daily (Nov. 30, 2009) — A new research report published in the December 2009 print issue of The FASEB Journal could one day give men similar type of control over their fertility that women have had since the 1960s. That's because scientists have found how and where androgenic hormones work in the testis to control normal sperm production and male fertility. This opens a promising avenue for the development of "the pill" for men.

The Scientific Tragedy of Climategate
From Reason.com:
Can climate change science recover from the damage done by leaked emails?
Climategate. What a hot mess. Researchers at the Climatic Research Unit (CRU) at the University of East Anglia and their colleagues around the globe may have fiddled with historical climate data and possibly the peer review process to ensure that publicized temperature trends fit the narrative of man-made global warming—then they emailed each other about it. Now those emails and other documents have been splashed all over the Web. Revelations contained in the leaked emails are roiling the scientific community and the researchers may be in pretty serious trouble. But the real tragedy of the Climategate scandal is that a lack of confidence in climate data will seriously impair mankind's ability to assess and react properly to a potentially huge problem.

The Loneliness Of Three Degrees Of Separation
From New Scientist:
John Cacappio of the University of Chicago and his colleagues reckon that loneliness can spread through society like an infection.
Their study, published in this month's issue of the Journal of Personality and Social Psychology, draws on a large group of people living in a town in Massachusetts that had already been assigned as part of a heart health study.
This group of around 5,000 were given questionnaires to assess their loneliness every four years or so, enabling the researcher to track any "spread" in this gloomy emotion.

Genetics Rather Than Stress To Blame For Grey Hair
From The Telegraph:
Women who find themselves going grey should blame their parents rather than their stressful lifestyles, research has found.
Scientists studied more than 200 identical and non-identical twins between the ages of 59 and 81. They found that there was little difference between the greyness of identical twin sisters, implying that their varying lifestyles or upbringing had little impact.
Among non-identical siblings that did have differing levels of grey hair, 90 per cent of cases could be attributed to differing genetic factors, researchers from Unilever, who conducted the research published it in US journal PLoS ONE, found.

Space Station Crew Lands In Kazakhstan
From Space.com:
A Canadian, a Russian and a Belgian astronaut left the International Space Station and landed on the icy steppes of Kazakhstan Tuesday aboard a Russian Soyuz spacecraft.
Belgian astronaut Frank DeWinne, Russian cosmonaut Roman Romanenko and Canadian astronaut Bob Thirsk touched down in their Soyuz TMA-15 crew capsule at 2:15 a.m. EST (0715 GMT) after heavy parachutes slowed the craft's descent.
The landing went smoothly, though the subzero temperatures in Kazakhstan prevented helicopters from flying to retrieve the crew as usual. Instead, the Russian Federal Space Agency sent teams in all-terrain vehicles to recover the spaceflyers.

'Global Surge' In Rhino Poaching
From BBC:
Rhino poaching around the world is on the rise despite efforts to protect the animals, a report warns.
The global surge in the illegal trade has been driven by demands from Asian medicinal markets, the study by conservationists concluded.
It suggests that a decline in law enforcement is the main reason for the rise in poaching in Africa.
The report found that 95% of rhino poaching in Africa since 2006 had occurred in Zimbabwe and South Africa.

From The Guardian:
After 400 generations of stable weather, the world is on the brink of violent climate change. But there is good news too.
For about 10,000 years, our climate on Earth has been stable. Remarkably stable, in fact. Since the end of the last ice age, we humans have spent 400 generations taking advantage of this stability to build our civilisation.
We have had warm periods and little ice ages; but the changes have been small. We have always known pretty much when it will rain, what the temperature will be each summer and winter, and how high the rivers will flow.

Buried Treasure
Face from a Coffin. Egypt, Third Intermediate Period, 1075-656 B.C. Coffin sculptures such as this were first covered with gesso as a primer before being painted. The gesso and most of the paint have worn off, revealing the wood underneath. Three thousand years later, you can still see the sculptor's hand in the carving marks.
From Archaeology News/Forbes:
The Brooklyn Museum scours its archives for a show on ancient Egypt.
Besides ensuring tourism and providing storylines for scores of feature films, the mystique of ancient Egypt also launched a specific sort of museum show that has become de rigueur for large institutions: the blockbuster. When the traveling exhibition Treasures of Tutankhamun came to the Metropolitan Museum of Art in 1979, it broke all the museum's previous attendance records and became famous enough to merit a spoof on Saturday Night Live.

Is The Once-Stable Part Of Antarctica Starting To Melt?
From Discover Magazine:
Climate change doesn’t affect all places equally, and while Greenland and West Antarctica’s glaciers have started slipping into the sea at an alarming rate, East Antarctica was actually gaining ice. But now that could be changing, as a Nature Geoscience study done with data from NASA’s gravity-measuring satellites called GRACE suggests that the area could now be losing mass.

Why Do NASA Launch Times Depend On Lighting Conditions?
From The Air & Space Smithsonian:
It's all about the solar beta angle.
While it was a hydrogen leak on the pad that forced NASA to scrub the launch of space shuttle mission STS-127 on June 17, one main reason the agency had to wait several weeks to try again was something called a “solar beta angle cut-out.”
Solar what?
Before sending a shuttle aloft, mission planners carefully calculate the angle defined by its orbital plane around Earth and a line drawn from the center of Earth to the center of the sun. This “solar beta angle” changes constantly as Earth moves around the sun and the shuttle’s orbital plane precesses, or slowly shifts, due to the gravitational tug from Earth’s equatorial bulge.
