CSHL neuroscientists pinpoint location of fear memory in amygdala
One of the neuroscience groups at CSHL has shed new light on the brain circuit that is involved in fear learning, memory, responses.

Cities affect temperatures for thousands of miles
Even if you live more than 1,000 miles from the nearest large city, it could be affecting your weather.

Demagnetization by rapid spin transport
The fact that an ultrashort laser pulse is capable of demagnetizing a ferromagnetic layer in a jiffy has been well-known since approximately 1996.

Measuring the consequence of forest fires on public health
Pollution from forest fires is impacting the health of people with asthma and other chronic obstructive lung diseases, finds a study in Biomed Central's open access journal Environmental Health.

Poor sleep in old age prevents the brain from storing memories
The connection between poor sleep, memory loss and brain deterioration as we grow older has been elusive.

Patients' own skin cells are transformed into heart cells to create 'disease in a dish'
In a paper published Jan. 27 in Nature, researchers at Sanford-Burnham Medical Research Institute and Johns Hopkins University unveil the first maturation-based

ASU scientists unravel the mysteries of spider silk
Scientists at Arizona State University are celebrating their recent success on the path to understanding what makes the fiber that spiders spin - weight for weight - at least five times as strong as piano wire.

Rice technique points toward 2-D devices
Rice scientists have created a process to make patterns in atom-thick layers that combine a conductor -- graphene -- and an insulator -- hexagonal boron nitride.

In breast cancer metastasis, researchers identify possible drug target
The spread of breast cancer to distant organs within the body, an event that often leads to death, appears in many cases to involve the loss of a key protein, according to UC San Francisco researchers, whose new discoveries point to possible targets for therapy.

Singapore scientists led by A*STAR's GIS identify 4 mechanisms that contribute to gastric cancers
Scientists at A*STAR's Genome Institute of Singapore headed a study that discovered four processes by which gastric cancer is formed.

Stem cells aid recovery from stroke
Stem cells from bone marrow or fat improve recovery after stroke in rats, finds a study published in BioMed Central's open access journal Stem Cell Research & Therapy.

Accelerating neutral atoms on a table top
Conventional as well as compact laser-based particle acceleration schemes hinge on accelerating electric fields and are therefore ineffective for neutral atoms, which do not respond to these fields.
