Method found to 'purify' partially entangled states
Entanglement, the bizarre quantum mechanical connection that can exist between particles, is an essential component in many quantum information processing applications.

Biblical hero Samson may have been sociopath as well as strongman, according to new research
Samson, the Israelite hero and judge who was undone by the temptress Delilah, exhibited almost all of the symptoms of a person with Antisocial Personality Disorder, known in the psychology trade as ASPD.

Researchers identify gene related to infant lung disease
A multi-center team of researchers has discovered a possible genetic cause of infant lung disease.

Picky molecular traps snare problem chemicals from proces streams, effluents
The new microporous materials, named Sandia Octahedral Molecular Sieves (SOMS), could be useful in microelectronics fabrication and other industries where purification of, or extraction from, liquid process or waste streams is a significant or costly problem; It could also help capture for reuse a variety of valuable materials from industrial effluents.

Simple sandpile model helps solve problems of fusion power
Physicists from the University of Warwick, and the EURATOM/UKAEA fusion research programme at the Culham Science Centre, have found a new simple way of using the science of 'sandpiles' to achieve a clear model of how fusion plasma 'self organises' into a superstable state - a key to fusion power generation.

Patient power
People with inherited diseases are gaining a global voice through a new movement set to support and control medical research into these illnesses.

One in three fatal bicycle accidents linked to alcohol
Drinking alcohol and bicycling don't mix well, say Johns Hopkins researchers, whose study of 466 Maryland bicyclists found that a third of fatally injured riders had elevated blood alcohol levels at the time of their accident.

Diagnosing schizophrenia
A controversial computer program modelled on the human brain aims to pick out early signs of schizophrenia.

All specialized insect predators not suitable for biological control
An enemy is an enemy is an enemy, but some natural enemies are better than others at controlling prey populations and some enemies are ineffective, even though they are specialized, according to a Penn State entomologist.

Age and preexisting health problems affect the prognosis
Older women who had other health problems when they were first diagnosed with breast tumors received less aggressive cancer treatment and pretreatment assessments than women who were younger and healthier, according to a new study by the National Institute on Aging (NIA) and the National Cancer Institute (NCI).

Understanding plastic "sharkskin": Results may pave way for eliminating
At a meeting of the Society of Rheology in Hilton Head, polymer physicists at the National Institute of Science and Technology announced new insights into the causes--and solutions--for plastic

National registry established for alopecia areata
A national registry for alopecia areata, a disease whose hallmark is unexplained hair loss, has been established by the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS), a part of the National Institutes of Health (NIH).

Salmon habitat, hydropower problems focus of ORNL projects
Thousands of miles from the Pacific Northwest, researchers at the Department of Energy's Oak Ridge National Laboratory (ORNL) work to preserve the salmon habitat and balance power generation needs.

For orbiting satellites, kinetic kill weapons: Magnetic field shocklessly shoots pellets 20 times faster than rifle bullet
A magnetic field that accelerates pellets faster than anything except a nuclear explosion has been developed experimentally at Sandia National Laboratories.

High blood levels of Hepatitis C in patients co-infected with the Human Immunodeficiency Virus (HIV) may increase the risk of developing AIDS
Researchers at Cedars-Sinai Medical Center report that high amounts of Hepatitis C (HCV) in the blood and simultaneous co-infection with the human immunodeficiency virus (HIV) may be linked to a greater risk of developing AIDS and AIDS related death.

Quitting smoking doesn't erase increased risk of brain hemorrhage, UB study finds
Cigarette smoking increases the risk of brain hemorrhage, and the risk persists even after an individual quits smoking, evidence from a new study by University at Buffalo stroke researchers shows.

Robots with real muscles
The first robot to be powered by real muscles has been developed by American researchers.
