Toxicologist Edward Calabrese of the University of Massachusetts Amherst has dropped cultural bombs on both the U.S. National Academy of Sciences and two scientists who provided crucial information for Atomic Age carcinogen risk assessment.

Regarding the linear no threshold (LNT) dose-response approach to ionizing radiation exposure in the 1950s, Calabrese says there was deliberate suppression of evidence to prevent the regulatory panel from considering an alternative, threshold model - the LNT model was later generalized to chemical carcinogen risk ssessment.

An international analysis of conservation biologists finds that they work late at night and over weekends - just like much of the salaried corporate world and science writers. 

Thanks to athletes like Ryan Braun and Lance Armstrong, doping has gotten a bad rap, but if solar power is ever going to be viable, doping will be essential.

Flexible thin film solar cells require fewer materials and can be manufactured in large quantities by roll-to-roll processing. One such technology relies on cadmium telluride (CdTe), which is a distant second to silicon-based solar cells but cheap in terms of production costs. Because they are grown on rigid glass plates, these superstrate cells have, however a big drawback: they require a transparent supporting material that lets sunlight pass through to reach the light-harvesting CdTe layer, thus limiting the choice of carriers to transparent materials.

While cultural pundits are worried about the health impact of obesity and which foods need to be more regulated to prevent chronic disease, a new analysis has found that incidents of ischemic stroke, the most common type of stroke caused by a clot in the blood vessels of the brain, has declined among most during the past decade. 

The nature of hypnotically suggested changes in perception has been controversial throughout the history of hypnosis. 

The major current hypotheses of hypnosis hold that we always actively use our own imagination to bring about the effects of a suggestion - for example, the occurrence of visual hallucinations always requires active use of goal directed imagery and can be experienced both with and without hypnosis. In other words, it isn't really hypnosis, but people susceptible to suggestion become more so when drowsy.

Sociologists have challenged the perception that there is a "new and pervasive hookup culture" among contemporary college students that is substantially greater than a generation ago.

People have always distrusted science, just like people have always been afraid of the supernatural (unless it promises a spiritual pot of gold at the end of your particular rainbow) but the naturalistic fallacy - that natural is somehow good and unnatural is somehow bad - is a recent invention.

New research just out in the journal Science Translational Medicine opens the door for treatments capable of stopping Alzheimer’s disease (AD) before its first symptoms, that is to say before crucial damage occurs. In fact, while AD is a devastating disorder, it is also an extremely slow one; it takes more than 10 years for the first symptoms to appear making this preclinical period (pre-symptoms) the ideal time to intervene. 

Excavations of tools at two neighboring Paleolithic sites in southwest France have made the blurred lines between modern humans and Neanderthals more blurry. 

Two research teams from the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, and the University of Leiden in the Netherlands have jointly reported the discovery of Neandertal bone tools unlike any others previously found in Neandertal sites - but similar to a tool from later modern human sites and still and still used even today. 

Near-death experiences may have found a new grounding in science.

Whether and how the dying brain is capable of generating conscious activity has been vigorously debated but the near-death experiences reported by cardiac arrest survivors worldwide may be verifiable, according to a new paper.

Approximately 20 percent of cardiac arrest survivors report having had a near-death experience during clinical death. These visions and perceptions have been called "realer than real" but it remains unclear whether the brain is capable of such activity after cardiac arrest.

A new paper found that shortly after clinical death, in which the heart stops beating and blood stops flowing to the brain, rats display brain activity patterns characteristic of conscious perception.
