Penguin tracking bands do harm
The bands that scientists attach to penguins to track them actually do harm. The data also suggests that certain climate research might also be skewed because of this. Key quote:
Overall, the team found, bands were bad for penguins. Banded penguins had a 16% lower survival rate than unbanded birds over the 10 years, the researchers report online today in Nature. Banded birds also arrived later at the breeding grounds and took longer trips to forage for food. As a result, they produced 39% fewer chicks. . . . [The researcher noted] that his team’s results suggest that research using banded penguins may be biased. For example, he says, several high-profile studies have used banded penguins to investigate the impact of climate change on the birds. The findings of those studies aren’t necessarily wrong, but the numbers need to be reconsidered, he says.
Preliminary findings suggest that the Arkansas birds died from impact trauma
Preliminary findings from the USGS National Wildlife Health Center suggest that the mass bird die-off that occurred in Arkansas was from impact trauma. Key quote:
The State concluded that such trauma was probably a result of the birds being startled by loud noises on the night of Dec. 31, arousing them and causing them to fly into objects such as houses or trees. Scientists at the USGS NWHC performed necropsies—the animal version of an autopsy—on the birds and found internal hemorrhaging, while the pesticide tests they conducted were negative. Results from further laboratory tests are expected to be completed in 2-3 weeks.
Russian scientists about to drill into Lake Vostok
Russian scientists are about to drill into Lake Vostok, a lake buried for the last 14 million years beneath the almost two and a half mile thick Antarctic icecap.
Long-term space flight may be a problem for human reproduction
Don’t plan that honeymoon yet! Long-term space flight may be a problem for human reproduction. Key quote:
If exercise keeps muscles in shape [in space], what countermeasure might astronauts use to maintain reproductive health?
Souza laughed.
“That’s a good question,” he said.
Viking Found Organics on Mars, Experiment Confirms
New research confirms that the Viking landers did find organics on Mars back in the 1970s. Listen also to the September 15, 2010 and September 23, 2010 radio interviews that John Batchelor and I did with Viking project scientist Gilbert Levin and Christopher McKay of the Ames Research Center on this very subject.

New research using DNA kills mites that are killing bees
Researchers think they have found a way to use DNA to kill the mite that is killing bees in Britain, without harming the bees themselves.

Amino acids found on meteorite that crashed in the Sudan
Dead alien life arrives on Earth! Not really but still exciting anyway: Scientists have found the remains of space-born amino acids — essential to life — in the meteorite that crashed in the Sudan in 2008. Key quote:
“This meteorite formed when two asteroids collided,” said Daniel Glavin of NASA’s Goddard Space Flight Center in Greenbelt, Md. “The shock of the collision heated it to more than 2,000 degrees Fahrenheit [1,093 degrees Celsius], hot enough that all complex organic molecules like amino acids should have been destroyed, but we found them anyway.”
The discovery is further evidence that the basic elements of life can form in even the most hostile of environments.
