Study predicts when invasive species can travel more readily by air

A new study forecasts when climate factors such as temperature, humidity and rainfall will match at geographically distant airline departure and destination points, which could help to shuffle invasive species, and the diseases they may carry, across the globe along existing flight routes.

Instant immunity through chemically programmable vaccination and covalent self-assembly

The experiments, thus far performed only in mice, appear to overcome a major drawback of vaccinations - the lag time of days, or even weeks, that it normally takes for immunity to build against a pathogen.

New treatment target for chronic abdominal pain

High levels of a protein linked to the way pain signals are sent to the brain led to a decrease in abdominal pain in a recent study in mice.

Researchers discover gene variation linked to cocaine addiction and cocaine-induced paranoia

Researchers from Boston University School of Medicine (BUSM) and Yale University School of Medicine and the University of Connecticut School of Medicine, have discovered that variants in the á-endomannosidase (MANEA) gene are associated with cocaine addiction and cocaine-induced paranoia in European American and African American populations.

Protein complex shown to play pivotal role in stem cell development

Scientists at the Stanford University School of Medicine have identified a protein complex important in controlling whether embryonic stem cells retain their ability to become any cell in the body - a quality called pluripotency - or instead embark on a pathway of maturation and specialization.

Prenatal molecular diagnosis for tuberous sclerosis complex

Geneticists from Boston University School of Medicine (BUSM) have reported the world's first series of cases of prenatal diagnosis for women at risk of having a child with tuberous sclerosis complex (TSC).

Alcohol-branded merchandise associated with drinking behaviors among teens

Between 11 percent and 20 percent of U.S. teens are estimated to own T-shirts or other merchandise featuring an alcohol brand, and those who do appear more likely to transition through the stages of drinking from susceptibility to beginning drinking to binge drinking, according to a report in the March issue of Archives of Pediatrics & Adolescent Medicine.

New clues about mitochondrial 'growth spurts'

Mitochondria are restless, continually merging and splitting. But contrary to conventional wisdom, the size of these organelles depends on more than fusion and fission, as Berman et al. show. Mitochondrial growth and degradation are also part of the equation.

New mechanistic explanation of how the brain interprets stress signals

Chronic stress takes a physical and emotional toll on our bodies and scientists are working on piecing together a medical puzzle to understand how we respond to stress at the cellular level in the brain.

Blocking one protein RANK function inhibits bone loss

Soo Young Lee and colleagues, at Ewha Womans University, Republic of Korea, have developed a cell-permeable inhibitor of the mouse protein RANK (which they termed RRI) that is likely to aid in the development of selective drugs to treat diseases that involve substantial bone loss, for example, osteoporosis, periodontitis, and arthritis.

Evidence appears to show how and where frontal lobe works

A Brown University study of stroke victims has produced evidence that the frontal lobe of the human brain controls decision-making along a continuum from abstract to concrete, from front to back.
