Researchers studying a rare, lethal childhood tumor of the brainstem discovered that nearly 80 percent of the tumors have mutations in genes not previously tied to cancer. Early evidence suggests the alterations play a unique role in other aggressive pediatric brain tumors as well.

A team of UCLA scientists has found that the pathogen that causes leprosy has a remarkable ability to avoid the human immune system by inhibiting the antimicrobial responses important to our defenses.

Genetics has provided surprising insights into why vaccines used in both the UK and US to combat serious childhood infections can eventually fail. The study, published today in Nature Genetics, which investigates how bacteria change their disguise to evade the vaccines, has implications for how future vaccines can be made more effective.

A study published in Nature Genetics today has found new evidence for a link between the body clock hormone melatonin and type 2 diabetes. The study found that people who carry rare genetic mutations in the receptor for melatonin have a much higher risk of type 2 diabetes.

UCLA researchers have explained the puzzling disappearing act of energetic electrons in Earth's outer radiation belt, using data collected from a fleet of orbiting spacecraft.

Cells trying to keep pace with constantly changing environmental conditions need to strike a fine balance between maintaining their genomic integrity and allowing enough genetic flexibility to adapt to inhospitable conditions. In their latest study, researchers at the Stowers Institute for Medical Research were able to show that under stressful conditions yeast genomes become unst

Researchers at Oregon Health & Science University (http://www.ohsu.edu) have discovered that a molecule critical to the development and plasticity of nerve cells – brain-derived neurotrophic factor (BDNF) -- is severely lacking in brainstem neurons in mutations leading to Rett syndrome, a neurological developmental disorder. The finding has implications for the treatment of neurological disorders,

The eyes are the window into the soul—or at least the mind, according to a new paper published in Perspectives on Psychological Science, a journal of the Association for Psychological Science. Measuring the diameter of the pupil, the part of the eye that changes size to let in more light, can show what a person is paying attention to. Pupillometry, as it's called, has been used in social ps

The ideal male contraceptive would be inexpensive, reliable, and reversible. It would need to be long acting but have few side effects. New research published in BioMed Central's open access journal Reproductive Biology and Endocrinology used commercially available therapeutic ultrasound equipment to reduce sperm counts of male rats to levels which would result in infertility in humans.

In a 2007 episode of the television show Boston Legal, a character claimed to have figured out that a cop was racist because his amygdala activated – displaying fear, when they showed him pictures of black people. This link between the amygdala and fear – especially a fear of others unlike us, has gone too far, not only in pop culture, but also in psychological science, say the authors of a new pa
