Crack in the case for supersolids: Reports of supersolid helium may have been premature
June 25, 2010 at 2:00 AM

New experiments are casting doubt on previously reported observations of supersolid helium. New research suggests that prior experiments that seemed to show signs of supersolidity were in fact the result of the plastic deformation of normal helium.

Possible role for Smurf1 in pulmonary arterial hypertension
June 25, 2010 at 2:00 AM

Pulmonary arterial hypertension is a progressive disease, marked by shortness of breath and fatigue which can be fatal if untreated. Increased pressure in the pulmonary artery and its branches is associated with dysfunctional growth control of endothelial and smooth muscle cells leading to excessive thickening of the blood vessel wall, obliteration of the lumen and right heart failure.

Researcher develops green, bio-based process for producing fuel additive
June 25, 2010 at 2:00 AM

A new green, bio-based method for producing a much-used fuel additive and industrial chemical that is currently made from petroleum products has been developed.

Blast resistance standards keep the boom from the room
June 24, 2010 at 2:00 PM

Standards for blast resistance among trash receptacles have now been published by the standards development organization ASTM International.

Ignoring stress leads recovering addicts to more cravings
June 24, 2010 at 2:00 PM

Recovering addicts who avoid coping with stress succumb easily to substance use cravings, making them more likely to relapse during recovery, according to behavioral researchers.

Babies' first bacteria depend on birthing method, says new study
June 24, 2010 at 2:00 PM

A new study indicates different delivery methods of newborn babies has a big effect on the types of microbial communities they harbor as they emerge into the world, findings with potential implications for the heath of infants as they grow and develop.

Liquid crystals light way to better data storage
June 24, 2010 at 11:00 AM

Currently, most liquid crystal technologies rely on physical or chemical manipulation, such as rubbing in one direction, to align molecules in a preferred direction. In an important advance, scientists in Japan have created a stable, rewritable memory device that exploits a liquid crystal property called the "anchoring transition."

Gay men's bilateral brains better at remembering faces, study finds
June 24, 2010 at 11:00 AM

A Canadian study finds that gay men can recall familiar faces faster and more accurately than their heterosexual counterparts.

'BC5' material shows superhard, superconducting potential
June 24, 2010 at 8:00 AM

What could be better than diamond when it comes to a superhard material for electronics under extreme thermal and pressure conditions? Quite possibly BC5, a diamond-like material with an extremely high boron content that offers exceptional hardness and resistance to fracture, but unlike diamond, it is a superconductor rather than an insulator.

Obesity, weight gain in middle age associated with increased risk of diabetes among older adults
June 24, 2010 at 8:00 AM

For individuals 65 years of age and older, obesity, excess body fat around the waist and gaining weight after the age of 50 are associated with an increased risk of diabetes, according to a new study.

Pre-stored phrases make it easier to be part of a conversation
June 24, 2010 at 8:00 AM

Researchers in Sweden have now developed a system where pre-stored phrases are used in addition to writing, with a view to making communication faster and more easy-going for people with serious speech disorders.

How lead exposure damages the brain: New research fills in the picture
June 24, 2010 at 8:00 AM

Exposure to lead during early childhood and even later in life has long been known to affect the release of critical neurotransmitters. However, the precise mechanism by which lead ions (Pb2+) impair this process has remained unknown. The study demonstrates that during the formation of synapses -- synaptogenesis -- exposure to lead alters the levels of several key proteins involved in neurotransmitter release.

Mechanism explains complications associated with diabetes
June 24, 2010 at 5:00 AM

New research uncovers a molecular mechanism that links diabetes with an increased risk of cardiovascular problems and sudden cardiac death. The study finds that high blood sugar prevents vital communication between the brain and the autonomic nervous system, which controls many involuntary activities in the body.

Young children are skilled negotiators, Swedish research finds
June 24, 2010 at 5:00 AM

Young children are skilled negotiators when it comes to relationships and the content of play, reveals new research from Sweden.

Studies confirm presence, severity of pollution in US national parks
June 24, 2010 at 5:00 AM

Toxic contamination from pesticides, the burning of fossil fuels, agriculture, industrial operations and other sources are a continuing concern in US national parks of the West, two new studies confirm.
