Person's brain age could help identify risk of functional decline and mortality

Some elderly people's brains appear older than the age on their birth certificates. These people have a higher risk of developing deteriorating age-associated conditions and impairments, and even of experiencing an earlier death than expected.

Researchers use novel phage therapy to treat patient infected with multidrug-resistant bacterium

Scientists and physicians at University of California San Diego School of Medicine, working with colleagues at the U.S. Navy Medical Research Center - Biological Defense Research Directorate, Texas A&M University, a San Diego-based biotech and elsewhere, have successfully used an experimental therapy involving bacteriophages -- viruses that target and consume specific strains of bacteria -- to treat a patient near death from a multidrug-resistant bacterium.

Researchers identify new rare genetic variants linked to extreme longevity

The search for the genetic determinants of extreme longevity has been challenging, with the prevalence of centenarians (people older than 100) just one per 5,000 population in developed nations.

Enzyme treatment may prevent or reduce liver damage caused by excess alcohol consumption

An intestinal enzyme previously shown to keep bacterial toxins from passing from the gastrointestinal system into the bloodstream may be able to prevent or reduce the liver damage caused by excess alcohol consumption.

Caltech researchers discover brain region that judges intensity, ambiguity of facial expressions

Have you ever thought someone was angry at you, but it turned out you were just misreading their facial expression? Caltech researchers have now discovered that one specific region of the brain, called the amygdala, is involved in making these (sometimes inaccurate) judgments about ambiguous or intense emotions.

Study finds link between fertility treatments and pediatric tumors

Ben-Gurion University of the Negev researchers have found that babies born from mothers who underwent fertility treatments are at increased risk of developing many types of pediatric cancers and tumors (neoplasms).

Research shows how TET2 protein loss can open door for mutations that drive blood cancers

Imagine this scenario on a highway: A driver starts to make a sudden lane change but realizes his mistake and quickly veers back, too late. Other motorists have already reacted and, in some cases, collide. Meanwhile, the original motorist - the one who caused the problem - drives on.

Mental illness does not impact bariatric surgery outcomes, study finds

People with pre-existing mental health conditions had nearly identical results in weight loss after bariatric surgery as compared to those with no known mental health conditions.

Neurobiologists use skin stem cells to generate new microglia

Using human skin cells, University of California, Irvine neurobiologists and their colleagues have created a method to generate one of the principle cell types of the brain called microglia, which play a key role in preserving the function of neural networks and responding to injury and disease.

Scientists create new technique for studying how chlamydia interacts with immune system

Scientists at the Wellcome Trust Sanger Institute and their collaborators at the University of British Columbia have created an innovative technique for studying how chlamydia interacts with the human immune system.

KU Leuven researchers grow three-dimensional cultures of the uterus' inner lining in a dish

Scientists at KU Leuven, Belgium, have succeeded in growing three-dimensional cultures of the endometrium, the uterus' inner lining, in a dish.

Low levels of NPTX2 protein in the brain may lead to learning and memory loss in Alzheimer's disease

Working with human brain tissue samples and genetically engineered mice, Johns Hopkins Medicine researchers together with colleagues at the National Institutes of Health, the University of California San Diego Shiley-Marcos Alzheimer's Disease Research Center, Columbia University, and the Institute for Basic Research in Staten Island say that consequences of low levels of the protein NPTX2 in the brains of people with Alzheimer's disease (AD) may change the pattern of neural activity in ways that lead to the learning and memory loss that are hallmarks of the disease.

Return of malaria in the U.S. is costing millions, study claims

Malaria-related hospitalizations and deaths in the U.S. are far more common than expected, report researchers, despite transmission having been eliminated in the country back in the 1950s.

MRI-based method for predicting brain age could help identify people at risk of early death

A method for predicting someone's 'brain age' based on MRI scans could help to spot who might be at increased risk of poor health and even dying at a younger age.

Novel mechanism of antidepressant action may benefit patients unresponsive to SSRI treatment

Antidepressants treat symptoms of depression by increasing levels of brain signaling molecules such as serotonin, as with the most widely used type of antidepressant, selective serotonin reuptake inhibitors.

Combination of genetics and experience gives each individual a unique sense of smell, study finds

Researchers from the Wellcome Trust Sanger Institute and their collaborators have shown that receptors in the noses of mice exposed to certain smells during life are different to genetically similar mice that lived without those smells.

Study finds significant decrease in cardiovascular diseases among individuals with diabetes

The incidence of cardiovascular diseases in Sweden has decreased sharply since the late 1990s. These are the findings of a study from Sahlgrenska Academy which included almost three million adult Swedes. In relative terms, the biggest winners are persons with type 1 and type 2 diabetes.

Mayo Clinic study shows surgery could more than double life expectancy for kidney cancer patients

Mayo Clinic researchers have discovered that surgery could more than double life expectancy for many patients with late-stage kidney cancer, giving them anywhere from two to almost 10 years more than they'd have without the surgery.

Genetic factors may increase person's risk for adverse effects of synthetic cannabinoids

Synthetic cannabinoid abuse is a growing problem in the United States, with new versions of the drugs coming on the market every year. New research is examining how the body processes these man-made drugs and the role that genetics might play in their metabolism.

Youth with uncomplicated epilepsy have favorable social outcomes as their siblings

A 15-year follow-up study of young adults with epilepsy found that those with uncomplicated epilepsy who were seizure-free for five years or more did as well as their siblings without epilepsy in measures of education, employment, family arrangements and driving status.
