Researchers probe the optical properties of a novel kind of magnetism

2013-09-23
CAMBRIDGE, Mass-- Using low-frequency laser pulses, a team of researchers has carried out the first measurements that reveal the detailed characteristics of a unique kind of magnetism found in a mineral called herbertsmithite. In this material, the magnetic elements constantly fluctuate, leading to an exotic state of fluid magnetism called a "quantum spin liquid." This is in contrast to conventional magnetism, found in materials called ferromagnets — where all of the magnetic forces align in the same direction, reinforcing each other — or antiferromagnets, where adjacent ...

Eagle vs. deer

2013-09-23
NEW YORK (September 18, 2013) — A camera trap set out for endangered Siberian (Amur) tigers in the Russian Far East photographed something far more rare: a golden eagle capturing a young sika deer. The three images only cover a two-second period, but show an adult golden eagle clinging to the deer's back. Its carcass was found two weeks later, just a few yards from the camera, initially puzzling researchers. The paper and images appear in the September issue of the Journal of Raptor Research. Authors include Linda Kerley of the Zoological Society of London (ZSL) and ...

How 'bad' cholesterol causes atherosclerosis in humans: Stem cells play a key role

2013-09-23
BUFFALO, N. Y. -- University at Buffalo translational researchers are developing a richer understanding of atherosclerosis in humans, revealing a key role for stem cells that promote inflammation. The research was published last month in PLOS One. It extends to humans previous findings in lab animals by researchers at Columbia University that revealed that high levels of LDL ("bad") cholesterol promote atherosclerosis by stimulating production of hematopoietic stem/progenitor cells (HSPC's). "Our research opens up a potential new approach to preventing heart attack and ...

Protein explains increased asthma severity in children exposed to diesel exhaust from traffic

2013-09-23
A new study shows that exposure to diesel exhaust particles from traffic pollution leads to increased asthma severity in children. Moreover, the study finds that this is due to increased blood levels of IL-17A, a protein associated with several chronic inflammatory diseases, in children with high diesel exposure. The study by researchers at Cincinnati Children's Hospital Medical Center is published online in the Journal of Allergy and Clinical Immunology. The research, conducted in mice and in humans, showed that neutralizing IL-17A prevented airway inflammation. Neutralization ...

It takes a(n academic) village to determine an enzyme's function

2013-09-23
CHAMPAIGN, Ill. — Scientists have sequenced the genomes of nearly 6,900 organisms, but they know the functions of only about half of the protein-coding genes thus far discovered. Now a multidisciplinary effort involving 15 scientists from three institutions has begun chipping away at this mystery – in a big way. Their work to identify the function of one bacterial protein and the biochemical pathway in which it operates will also help identify the functions of hundreds of other proteins. A report of their new approach and findings appears in the journal Nature. The ...

Putting the spring back in broken hearts

2013-09-23
The threat from a heart attack doesn't end with the event itself. Blockage of blood flow to the heart can cause irreversible cell death and scarring. With transplants scarce, half the people who live through a heart attack die within five years. Scientists are trying to address this problem by engineering cardiac tissue to patch up damaged areas. Now doctoral students Sharon Fleischer and Ron Feiner — under the supervision of Dr. Tal Dvir of Tel Aviv University's Department of Molecular Microbiology and Biotechnology and the Center for Nanoscience and Nanotechnology — ...

Identifying trauma risk in small children early after an accident

2013-09-23
Accidents also traumatize small children. Around one in ten children still suffers from a post-traumatic stress disorder a year after a road accident or burn injury, reliving aspects of the traumatic experience in the form of flashbacks or nightmares. In doing so, young children keep replaying the stressful memories while avoiding anything that might remind them of the accident in any way. As a result of this constant alertness to threatening memories, the children can develop sleeping disorders, concentration problems or aggressive behavior. Assessing the risk of illness ...

Sensory illusion study provides new insight for body representation brain disorders

2013-09-23
People can be easily tricked into believing an artificial finger is their own, shows a study published today [23 September] in The Journal of Physiology. The results reveal that the brain does not require multiple signals to build a picture body ownership, as this is the first time the illusion has been created using sensory inputs from the muscle alone. The discovery provides new insight into clinical conditions where body representation in the brain is disrupted due to changes in the central or peripheral nervous systems e.g. stroke, schizophrenia and phantom limb syndrome ...

Calming fear during sleep

2013-09-23
CHICAGO --- A fear memory was reduced in people by exposing them to the memory over and over again while they slept. It's the first time that emotional memory has been manipulated in humans during sleep, report Northwestern Medicine® scientists. The finding potentially offers a new way to enhance the typical daytime treatment of phobias through exposure therapy by adding a nighttime component. Exposure therapy is a common treatment for phobia and involves a gradual exposure to the feared object or situation until the fear is extinguished. "It's a novel finding," ...

UCLA scientists explain the formation of unusual ring of radiation in space

2013-09-23
Since the discovery of the Van Allen radiation belts in 1958, space scientists have believed these belts encircling the Earth consist of two doughnut-shaped rings of highly charged particles — an inner ring of high-energy electrons and energetic positive ions and an outer ring of high-energy electrons. In February of this year, a team of scientists reported the surprising discovery of a previously unknown third radiation ring — a narrow one that briefly appeared between the inner and outer rings in September 2012 and persisted for a month. In new research, UCLA ...
