The Carnegie Institution for Science reports
"a much higher water content in the Moon’s interior than previous studies." For decades, the moon's water content was estimated at less than 1 part per billion; the new estimates range from 64 ppb to 5 parts per million. A scientist at Washington University said, "We can now finally begin to consider the implications—and the origin—of water in the interior of the Moon.”

Odds of Cooking the Grandkids
: "There is a horrible paper in this week's Proceedings of the National Academy of Sciences, which looks at how the limits of human physiology interact with upper-range global warming scenarios. The bottom line conclusion is that there is a small - of order 5% - risk of global warming creating a situation in which a large fraction of the planet was uninhabitable (in the sense that if you were outside for an extended period during the hottest days of the year, even in the shade with wet clothing, you would die)."

Yesterday (April 15), Representatives Doyle (D-PA), Waxman (D-CA), Wasserman-Schultz (D-FL), Harper (R-MS), Boucher (D-VA) and Rohrabacher (R-CA) introduced the Federal Research Public Access Act (HR 5037), a bill that would ensure free, timely, online access to the published results of research funded by eleven U.S. federal agencies.

Nothing succeeds like failure. [H]istory shows that breakthroughs often spring not from carefully laid plans, but from mischance or even sheer, ridiculous accidents. A stovetop spill heralded vulcanized rubber; the potency of uranium was revealed when a rock was left in a drawer among photographic plates. And great research seldom follows an unswerving path. At RCA in Princeton in the 1950s, David Sarnoff exhorted his team to invent a flat television that could hang on a wall. “There were an enormous number of failures,” says Princeton historian of science Michael Gordin — and instead of TVs, the world got the Seiko digital watch in 1973.

Sweet, sour, bitter, salty, umami, and.... fat? Dr. Russell Keast
, an Austrailian scientist who studies
"perceived flavour, consumer acceptance and preference of foods and nutrition," has conducted research exploring humans' apparent sixth taste perception: fat. The kicker? Sensitivity to the taste of fat was negatively correlated with fat intake and BMI. Dr. Keast discussed the results of his latest research

"We were concerned that the study would raise a lot of controversy and be misused," Pardo said. "We were right." Some practitioners
treat autistic children with the anti-inflammatory intravenous immunoglobulin
, citing a study
by Carlos Pardo, et al. showing inflammation in the brains of deceased autistic patients. Pardo: "modulators of immune reactions (e.g. intravenous immunoglobulins, IVIG) WOULD NOT HAVE a significant effect."
Others, following the work of Simon Baron-Cohen on autism and the male brain
, treat autistic children with testosterone inhibitors
, a prospect which Baron-Cohen says "fills me with horror." Another anti-inflammatory treatment, hyperbaric therapy, is supported by one recent clinical trial
, but looks bad in another
. Side effects include horrible death by fire

Americans like science.
But they think much less highly of American scientists than American scientists themselves do. Most scientists also rate media coverage of science as only fair or poor. Yet public knowledge of some scientific facts is .... not that bad (Section 7). A Pew Research Report reveals all.

The rise and fall of a physics fraudster. In the spring of 2002, the world’s most productive young scientist was a 31-year-old physicist at Bell Labs in New Jersey in the US. With eight papers published in
Science in 2001 alone, Jan Hendrik Schön was emerging with breathtaking speed as a star researcher in physics, materials science and nanotechnology...But in September 2002, managers at Bell Labs released a report [pdf] that...made clear that much of Schön’s data were fake. His discoveries were lies. Many of his devices had probably never existed...On the day of the report’s release, Schön was fired and fled the US to an unknown location.
In all, 21 of Schon's papers were withdrawn from Nature
and Physical Review Journals

-- or as O'Reilly might term the Social Graph
-- sort of mirrors the debate on 'brute force' algorithmic proofs
(that are "true for no reason
.) in which "computers can extract patterns in this ocean of data that no human could ever possibly detect. These patterns are correlations. They may or may not be causative
, but we can learn new things. Therefore they accomplish what science does, although not in the traditional manner... In this part of science, we may get answers that work, but which we don't understand. Is this partial understanding? Or a different kind
?" Of course, say some in the scientific community: hogwash
; it's just a fabrication of scientifically/statistically illiterate pundits, like whilst new techniques in data analysis
are being developed to help keep ahead of the deluge...

. Researchers unravel the complex combination of physical and emotional reactions that influence our perceptions of what tastes good. Once upon a time, flavor research was a matter of asking housewives to munch a few potato chips... Now it's about providing an exceptional flavor "experience." And as scientists learn to exploit the ways we perceive flavor, food manufacturers will be able to refine their products to appeal to us as individuals. Welcome to the world of personally tailored mass-produced food.

"In 2006, the Union of Concerned Scientists (UCS) and Public Employees for Environmental Responsibility (PEER) distributed
a 38-question survey to 5,918 FDA scientists to examine the state of science at the FDA. The results
paint a picture of a troubled agency: hundreds of scientists reported significant interference with the FDA’s scientific work, compromising the agency’s ability to fulfill its mission of protecting public health and safety."
