CNVs appear to play a significant role in early onset bipolar disorder

An international team of scientists, led by researchers at the University of California, San Diego School of Medicine, reports that abnormal sequences of DNA known as rare copy number variants, or CNVs, appear to play a significant role in the risk for early onset bipolar disorder.

Study measures brain activity in infants to better understand their pain response

Recently, the accuracy of current methods of pain assessment in babies have been called into question. New research from London-area hospitals and the University of Oxford measures brain activity in infants to better understand their pain response.

Scientists model brain structure to help computers recognize objects

An essential question confronting neuroscientists and computer vision researchers alike is how objects can beidentified by simply "looking" at an image. Introspectively, we know that the human brain solves this problem very well. We only have to look at something to know what it is.

ORNL tool reveals previously undiscovered role of retinoblastoma

Armed with a new ability to find retinal anomalies at the cellular level, neurobiologists at St. Jude Children's Research Hospital have made a discovery they hope will ultimately lead to a treatment for cancer of the retina.

Leishmania parasite develops combined resistance against drug, human immune system

Scientists of the Institute of Tropical Medicine (ITG) discovered a parasite that not only had developed resistance against a common medicine, but at the same time had become better in withstanding the human immune system.

People with smaller regions of brain's cortex more likely to develop early Alzheimer's

New research suggests that, in people who don't currently have memory problems, those with smaller regions of the brain's cortex may be more likely to develop symptoms consistent with very early Alzheimer's disease.

Bacteria use host proteins to build camouflaged homes inside healthy cells

Bacteria are able to build camouflaged homes for themselves inside healthy cells - and cause disease - by manipulating a natural cellular process.

Optical imaging can visualize cultured cancer cells' response to particular drug

Many cancer therapies target specific proteins that proliferate on the outside of some cancer cells, but the therapies are imperfect and the cancer does not always respond. Since it is beneficial for doctors to know as soon as possible how a cancer is affected by treatment, researchers from Vanderbilt University are striving to design tests that assess treatment response rapidly, accurately, and cost-effectively.

Research into how flying fox spreads infectious diseases

The flying fox is an adorable doe-eyed bat with a dark side - it is the perfect vector for emerging infectious diseases from Asia. Susan Tsang, a PhD student in ecology and evolutionary biology at The City College of New York and the CUNY Graduate Center, turned to a revolutionary way to help fund her research into how this species spreads disease.

Scientists identify why African naked mole-rat feels no pain when exposed to acid

British researchers of the Max Delbr-ck Center for Molecular Medicine (MDC) Berlin-Buch have found out why the African naked mole-rat (Heterocephalus glaber), one of the world's most unusual mammals, feels no pain when exposed to acid.

Study on how Antarctic worms survive current levels of ocean warming

Researchers at the University of Delaware are examining tiny worms that inhabit the frigid sea off Antarctica to learn not only how these organisms adapt to the severe cold, but how they will survive as ocean temperatures increase.

Researchers discover how spinning microparticles can direct neuron growth

Researchers at UC Irvine and The University of Texas at Arlington have discovered how spinning microparticles can direct the growth of nerve fiber, a discovery that could allow for directed growth of neuronal networks on a chip and improve methods for treating spinal or brain injuries.

Researchers discover one of vitamin E's normal body functions

It's rubbed on the skin to reduce signs of aging and consumed by athletes to improve endurance but scientists now have the first evidence of one of vitamin E's normal body functions.

Optical coherence tomography measures changes in retinal cone cells

Humans see color thanks to cone cells, specialized light-sensing neurons located in the retina along the inner surface of the eyeball. The actual light-sensing section of these cells is called the outer segment, which is made up of a series of stacked discs, each about 30 nanometers (billionths of a meter) thick. This appendage goes through daily changes in length.

New method uses cultured skin cells to detect contact allergy

Contact allergy affects around 20% of the population in the western world. Scientists are working intensively to develop alternative test methods that do not require animal testing. A research group at the University of Gothenburg, Sweden, has now developed a unique test method that enables graded results to be obtained using cultured skin cells.

CSF biomarkers can help detect early stage of Alzheimer's

Analysis of the cerebrospinal fluid can detect whether a person has Alzheimer's disease before symptoms appear. Researchers at the Sahlgrenska Academy at the University of Gothenburg, Sweden, have studied biomarkers that offer more reliable diagnosis and, in the longer term, the possibility of effective new treatments.
