Another psychologist has resigned amid questions over the validity of his research.

This and other recent cases (here, here, here, here, here, here) are more evidence that the peer review process in some fields is badly broken, that the reviewers are too often not doing the reviewing they are supposed to, and in some cases might very well be participating in scientific fraud themselves.

A student experiment that was successfully flown up and down to ISS by Dragon is apparently a failure because no one on ISS ever turned it on.

A student experiment — successfully flown up and down to ISS by Dragon — is apparently a failure because no one on ISS ever turned it on.

Per instructions from NanoRacks, the Houston company that works with NASA to integrate such deliveries, Warren packed his worms, or C. elegans, into a glass ampule, or tube, then packed that tube into a larger one containing a liquid “growth medium” for the worms. An astronaut aboard the space station was to crack the outer ampule in a way that would release the worms into the surrounding liquid. It never happened.

The article is very diplomatic about this, but it is very clear that either the astronauts on ISS screwed up, or NASA did by not giving them clear instructions.

New research suggests that — despite its known bad effects — weightlessness might actually slow the aging process.

New research suggests that — despite its known bad effects — weightlessness might actually slow the aging process.

Don’t jump into that spaceship yet! The research was done on worms, and is to put it mildly very preliminary. Moreover, none of the results change anything regarding the serious loss of bone density and the weakening of the muscles and cardiovascular system caused by weightlessness.

Six patients are suing one of the world’s largest stem cell companies, accusing it of fraud.

Six patients are suing one of the world’s largest stem cell companies, accusing it of fraud.

The patients claim that at RNL workshops they were misled into believing that treatments, still in the experimental stage, had already been proven effective. They allege that Hong told them stem cells would cure all ailments from which they suffered, including diabetes, arthritis, high blood pressure, back pain and insomnia, and “reverse aging, restore health and virility including sex drive, and rejuvenate their body functions to that of their twenties and thirties.” They all say they have received no benefit from the treatments.

Altogether these patients spent $75,000 for these treatments.

It is very suspicious for any respectable medical institution to charge patients for experimental work. That should have been a red flag from the beginning.

How the Higgs boson explains the universe.

How the Higgs boson explains the universe.

And what it can’t explain:

The discovery [by the existence of the Higgs boson] that nature is beautifully symmetric means we have very little choice in how the elementary particles do their dance – the rules simply “come for free”. Why the universe should be built in such an elegant fashion is not understood yet, but it leaves us with a sense of awe and wonder that we should be privileged to live in such a place.

Science discovers how the universe operates. Philosophy and religion try to explain why. Thus, it is perfectly reasonable in a rational world to consider the existence of God, and why musings about the possibility of intelligent design do not contradict pure science.

And I speak not as a religious person, but as a secular humanist.

Astronomers have found four different binary star systems with the stars orbiting so close to each other that they complete their orbits in less than four hours, orbits that astronomers had previously believed “impossible.”

The uncertainty of science: Astronomers have found four different binary star systems with the stars orbiting so close to each other that they complete their orbits in less than four hours, orbits that astronomers had previously believed “impossible.”

From CERN: The experiments have observed a “particle consistent with long-sought Higgs boson.”

From CERN: The experiments there have now observed a “particle consistent with long-sought Higgs boson.”

The press release also emphasizes repeatedly the preliminary nature of this result. More details in this article, including this not unexpected punchline if you know science:

Already, the new boson seems to be decaying slightly more often into pairs of gamma rays than was predicted by theories, says Bill Murray, a physicist on ATLAS, the other experiment involved in making the discovery.

Since 2006 carbon dioxide emissions in the U.S. has plunged, almost reaching 1991 levels.

Since 2006 carbon dioxide emissions in the U.S. have plunged, almost reaching 1991 levels.

The key driver for the “shockingly good news” that CO2 emissions will probably fall this year to a two-decade low … is “the shale gas revolution, and the low-priced gas that it has made a reality, especially in the last 12 months. As of April, gas tied coal at 32% of the electric power generation market, nearly ending coal’s 100 year reign on top of electricity markets (see related CD post on this energy milestone). Let’s remember the speed and extent of gas’s rise and coal’s drop: coal had 52% of the market in 2000 and 48% in 2008.”

It is important to note that it is innovation, technology, and capitalism that is making this happen. Without a free market the shale gas revolution would not have occurred.

A investigation has found that Japanese anesthesiologist, Yoshitaka Fujii, fabricated a 172 scientific papers over the past 19 years.

A investigation has found that Japanese anesthesiologist, Yoshitaka Fujii, fabricated a 172 scientific papers over the past 19 years.

The panel focused on 212 of 249 known Fujii papers. It tried to review the raw data, laboratory notebooks, and records on the patients or animal subjects involved. Committee members also interviewed relevant people. Among the 172 papers judged bogus, the report claims that 126 studies of randomized, double-blind, controlled trials “were totally fabricated.” The committee identified only three valid papers. For another 37 papers, the panel could not conclusively determine if there had been fabrication. …

The panel said that the responsibility of those co-authors ranges from “serious” to “none at all.” The only one of Fujii’s co-authors specifically named in the summary is University of Tsukuba anesthesiologist Hidenori Toyooka. The report says Toyooka “was not involved in fabrication but bears significant responsibility” since he was Fujii’s supervising professor both at Tsukuba and when they both worked at Tokyo Medical and Dental University. Toyooka is listed as a co-author of many of the papers cited by the 23 journal editors. … At the same time, the investigation found that some scientists were unaware Fujii had included them as co-authors. In one case, two supposed co-authors told the panel their signatures on a submission cover letter were forged. [emphasis mine]

For a scientist to get that many fabricated papers published for that long in peer-reviewed journals strongly suggests that there is widespread corruption in his field, which in this case is anesthesiology.
