Effort to drill into ancient lake under Antarctica icecap fall short
Wait ’til next year! The Russian effort to drill into Lake Vostok buried under the Antarctica icecap has fallen short by only a hundred feet, stopped by the end of summer.

White nose confirmed on Indiana bats
White nose syndrome, a fungus that is linked to the death of approximately a million bats throughout the eastern United States, has now been confirmed on two Indiana bats. You can read the actual Indiana Department of Natural Resources press release here. [pdf]
The bats are thus finally spreading the fungus north, as has been expected.

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.

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.

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.

NASA’s arsenic biology discovery slammed
The uncertainty of science! A microbiologist is slamming last week’s NASA discovery that claimed a microbe had incorporated arsenic instead of phosphorus as part of its DNA. Key quote:
In an interview Monday, Redfield said the methods used by the researchers were so crude that any arsenic they detected was likely from contamination. There is no indication that the researchers purified the DNA to remove arsenic that might have been sticking to the outside of the DNA or the gel the DNA was embedded in, she added. Normally, purifying the DNA is a standard step, Redfield said: “It’s a kit, it costs $2, it takes 10 minutes.” She also questioned why the researchers analyzed the DNA while it was still in the gel, making the results more difficult to interpret: “No molecular biologist would ever do that.”
Killing bats to save them!
In a wonderful example of government stupidity, environmental officials in Wisconsin want to try to “exclude” bats from caves in order to prevent the spread of white nose syndrome.
Some quick background: White nose syndrome appeared in upstate New York about four years ago, killing about 90 percent of the bats affected. It has since spread down the east coast following bat migration patterns as they travel during the summer months. (While human activity might spread the syndrome as well, the evidence all points to the bats as the primary vector.) A newly discovered fungus that is seen on all affected bats, for which the syndrome is named, is the prime suspect for killing them, as it disturbs them during hibernation, causing them to wake more frequently, burn up their reserves,and thus starve to death.
Wisconsin officials, in their infinte wisdom, have decide that the way they will save the bats of their state will be to declare the fungus an invasive specie. They will then be empowered to do anything they can to prevent its spread. And how will they do this? By preventing bats from entering caves and bringing the fungus with them.
Let me say that again: Wisconsin environment officials want to “exclude bats from caves” in order to save them. The result of course will be a biological genocide, since without access to caves during the cold hibernation period the bats will surely die.
If you don’t believe me, see this press release. To quote:
The third proposed rule adds provisions to NR 40.04 and 40.07 relating to early detection and prevention of the spread of the disease due to human activities, including the decontamination of clothes and equipment that have been used in mines or caves, and limited access of bats or people to caves or mines. [emphasis mine]
If you still don’t believe me, read the state’s actual proposed management plan [pdf]. To quote page 5:
Under the proposed rules, the department may ask any person who owns, controls, or manages property here a cave or mine may be present to install and properly maintain physical barriers to limit access to the cave or mine by either individuals or bats, in accordance with a plan approved by the department. The department is seeking funding to assist with the installation of barriers, and therefore cost to those parties who install such barriers should be negligible. Additionally, commercial caves will have the option to exclude bats from their cave(s) with the help of the department, allowing them to remain open for tourism, and resulting in no loss of tourism dollars. [emphasis mine]
Moreover, this plan will give these officials the power to enter private property without the landowners’ permission.
Cavers have been trying to explain to the Wisconsin officials that this entire approach is madness. So far, these pleas have had very little effect. You can see their efforts here.
This whole story might be one of the best examples of why it is always bad idea to concentrate a lot of power in the hands of government. Better to spread the power around among a lot of private landowners, as then you also spread the stupidity around as well, and reduce the chances that the only approach taken is the worse approach.
