The second X-37b is in orbit

The second X-37b is in orbit. Key quote:

Similar to [Orbital Test Vehicle-1] , [Orbital Test Vehicle-2]’s actual mission duration will depend on the vehicle achieving its test objectives, but he expects it to remain on orbit for approximately 270 days. “We may extend the mission to enhance our understanding of the OTV capabilities,” Colonel Giese said, “especially since the performance data from the first flight suggest that the vehicle could have gone beyond the 270-day requirement.”

Has a NASA scientist discovered alien fossils in several meteorites?

10:09 am

alien fossil?

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.)

Fraud in drug studies investigated

3:49 pm

A research anesthesiologist has been stripped of his professorship, fired from a German hospital, and is under criminal investigation for forging the medical research for more than 90 papers. Key paragraph:

German medical authorities are examining 92 of Boldt’s published papers amid allegations he forged documents, tested drugs on patients without their consent and fraudulently claimed payments for operations he never performed. Twenty-nine of the 92 papers have been identified as “highly suspected” of containing forged or distorted data, authorities said.

One third or more of his peer-reviewed papers are now suspect? Isn’t it the claim of peer-review science journals that this kind of fraud is impossible because the work will be carefully reviewed by the best people, most qualified to spot any fraud in their field? Yet, in this case this system failed at least one third of the time, if not more so, and did so frequently.

To me, this is further evidence that the best method for finding fraud is not review, but independent competition. Let others challenge the result or try to duplicate it. That way, we find out very quickly whether it is real or not.

Water and ice at the bottom of the Antarctic Ice Sheet

11:27 pm

The uncertainty of science: Unexpectedly large amounts of flowing water and refrozen ice found at the bottom of the Antarctic icecap. Key quote:

It’s too early to know whether this new finding means that global warming will melt ice sheets slower or faster than scientists have predicted. But the work does suggest that current models of ice sheet dynamics are missing a huge factor, said glaciologist Donald Blankenship of the University of Texas, Austin. “The take-home message of this work is that [the bottom of ice sheets] can no longer be ignored” in the models, he says.

More press release journalism,
this time about sunspots

10:01 am

Did you hear the news? Scientists have solved the mystery of the missing sunspots!

You didn’t? Well, here’s some headlines and stories that surely prove it:

The trouble is that every one of these headlines is 100 percent wrong. The research, based on computer models, only found that when the plasma flow from the equator to the poles beneath the Sun’s surface slows down, the number of sunspots declines.
