Some detailed analysis by scientists of meteorite fossil paper
Here’s some detailed analysis by scientists of the meteorite fossil paper.
Once again, there is a great deal of skepticism, most of which appears reasonably and justified. Though a number of scientists have applauded his work, it really looks like Hoover does not have sufficient evidence to claim his samples are alien biology. However, this quote stands out:
It appears likely that Hoover’s study may soon be ignored by the majority of the scientific community, instead of enjoying a healthy debate such as that raised by McKay’s 1996 paper on the Mars meteorite. Redfield says that a microbiologist that she knows refused to read it. [emphasis mine]
That hardly seems the right response from an open-minded scientist.

Planetary scientists reject meteorite fossil paper — without reading it
Richard Kerr of Science is attending the annual Lunar and Planetary Science Conference in Texas, and has written a short article describing the reaction of planetary scientists to the meteorite fossil paper by NASA scientist Richard Hoover. Their reaction, hostile and disinterested, isn’t pretty. These two quotes will give you the flavor:
Whether they have closely examined the paper by astrobiologist Richard Hoover of NASA’s Marshall Space Flight Center or only heard about it in the hallways, the reaction is the same: not again.
Rather than taking a look themselves, researchers have other things in mind. One leading scientist half-jokingly suggested hanging Hoover in effigy in the conference center lobby.
NASA Statement on Astrobiology Paper by Richard Hoover
In an unusual move, NASA has issued a statement on the alien fossil paper written by Richard Hoover. Key quote:
While we value the free exchange of ideas, data, and information as part of scientific and technical inquiry, NASA cannot stand behind or support a scientific claim unless it has been peer-reviewed or thoroughly examined by other qualified experts. This paper was submitted in 2007 to the International Journal of Astrobiology. However, the peer review process was not completed for that submission. NASA also was unaware of the recent submission of the paper to the Journal of Cosmology or of the paper’s subsequent publication.
This suggests that Hoover was having trouble getting published in one journal, and did an end-around to get published in a journal more agreeable to his conclusions.
Though this does raise questions about the validity of the research, it is always the research itself that matters. In this case I remain skeptical, but intrigued. I really would like to know why the peer-review process on Hoover’s paper was taking so long at the International Journal of Astrobiology. I would also love to read a critique of Hoover’s papers from scientists in the field.

Has a NASA scientist discovered alien fossils in several meteorites?
Very very intriguing: A NASA scientist has claimed in a peer reviewed paper the discovery of alien fossils in several meteorites recovered on Earth. From the paper’s last paragraph:
The absence of nitrogen in the cyanobacterial filaments detected in the CI1 carbonaceous meteorites indicates that the filaments represent the remains of extraterrestrial life forms that grew on the parent bodies of the meteorites when liquid water was present, long before the meteorites entered the Earth’s atmosphere.
The news article describing this discovery is a bit more breathless in style than I would like, and makes me suspicious about these results. Moreover, that NASA held no press release or press conference for a result of this significance gives me pause. (Though NASA might have felt burned from the reactions they got from the arsenic-based-biology press conference and decided therefore to take a low profile here.)

Researchers discover a new set of deep-sea volcanic vents in the south Pacific
Researchers have discovered a new set of deep-sea volcanic vents in the south Pacific, suggesting these vents are more common than previously believed. Key quote:
Using an underwater camera system, the researchers saw slender mineral spires about 10 feet tall, with hot water gushing from their peaks, and white mats of bacteria coating their sides. The vents are at a depth of 1,706 feet in a newly discovered seafloor crater close to the South Sandwich Islands, a remote group of islands about 310 miles southeast of South Georgia.

White nose found in North Caroina
The fungus that has been killing cave hibernating bats throughout the eastern United States has now been found in North Carolina.
In a related note, the National Speleological Society has sent a letter to the U.S. Fish and Wildlife Service, expressing its concern over what many cavers believe has been the government’s indiscriminate cave closure policies in response to the white nose fungus. Key quote:
Our members have been extremely patient and collaborative throughout the entire [white nose syndrome] situation, but the frustration and discontent has been growing. We are hearing more and more from across the country that cavers do not want to participate in collaborative efforts – in much part due to management decisions by federal and state agencies that are perceived by knowledgeable and conservation-minded cavers to be over-reactive, based on sometimes slim science, speculation and political pressure, and insensitive to broader science and conservation issues. That result would not be beneficial to anyone.

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.

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.
