A team of cancer specialists and health economists have developed a tool that can measure a patient's risk for, and ability to tolerate, the financial stress associated with treatment.

PTSD experts agree that the condition has its roots in very real, physical processes within the brain – and not some sort of psychological "weakness". But no clear consensus has emerged about what exactly has gone "wrong" in the brain. A new theory that integrates decades of research focuses on a…

Leading-edge research has shown for the first time that a malfunctioning stress-coping mechanism in the brain is at the root of Parkinson's disease. Genetic mutations that cause Parkinson's disease can prevent synapses – the junctions between neurons where electrical signals are transmitted – from…

New research reveals endoglin as a critical factor in determining the fate of early undifferentiated cells during development. Endoglin, a receptor involved in cell signaling, has previously been known mostly for its function in blood vessels and angiogenesis. Researchers showed endoglin modulates…

Mathematical modeling of the brain scans of patients with Alzheimer's disease and others at risk for the devastating neurodegenerative disorder has identified specific patterns of brain atrophy that appear to be related to the loss of particular cognitive abilities.

For the first time, the mechanism that regulates fluid intake in the human body and stops us from over-drinking has been revealed by researchers. Over-drinking can cause potentially fatal water intoxication. The study challenges the popular idea that we should drink eight glasses of water a day for…

Nurturing caregiving from a few consistent individuals helps to minimize the potential emotional and mental-health development issues that can arise from spending the early years of a child's life in an institution. Within such facilities, infants and toddlers reared in daily contact with…

Although our knowledge of the human DNA is extensive, it is nowhere near complete. For instance, our knowledge of exactly which changes in our DNA are responsible for a certain disease is often insufficient. This is related to the fact that no two people have exactly the same DNA. Even the DNA…

Scientists have long understood that mother's milk provides immune protection against some infectious agents through the transfer of antibodies, a process referred to as "passive immunity." A research team now shows that mother's milk also contributes to the development of the baby's own immune…

New research has demonstrated that a nanoscale device, called a memristor, could be used to power artificial systems that can mimic the human brain. Artificial neural networks (ANNs) exhibit learning abilities and can perform tasks which are difficult for conventional computing systems, such as…

Social and economic factors have led to a dramatic rise in type 2 diabetes and obesity around the world. In a new review, researchers examine the knowledge of the actual causes and the interplay between genetics and lifestyle factors.

Researchers present new findings on the role of the protein Tau in certain brain diseases. Their report, which is based on laboratory studies, suggests that the drug "Rolofylline" could possibly alleviate learning and memory problems associated with aggregating Tau proteins.

Cells never forget to take out the trash. It has long been known that cells tag proteins for degradation by labeling them with ubiquitin, a signal described as "the molecular kiss of death". Now a research group has identified an analogous system in gram-positive bacteria, where the role of a…

People who carry variants in a particular gene have an increased preference for high fat food, but a decreased preference for sugary foods, according to a new study. The research has provided insights into why we make particular food choices, with potential implications for our understanding of…

A new report suggests hospital rankings may not be as reliable as thought. Researchers found that false-positive event rates were common among high-transfer and high-volume hospitals.

Researchers have discovered a previously unknown mass migration of inhibitory neurons into the brain's frontal cortex during the first few months after birth, revealing a stage of brain development that had previously gone unrecognized. The authors hypothesize that this late-stage migration may…

Bionic enzymes got a needed boost in speed thanks to new research. By pairing a noble metal with a natural enzyme, scientists created a hybrid capable of churning out molecules at a rate comparable to biological counterparts.

Despite their different triggers, the same molecular chain of events appears to be responsible for brain cell death from strokes, injuries and even such neurodegenerative diseases as Alzheimer's. Now, researchers say they have pinpointed the protein at the end of that chain of events, one that…
