NIH researchers unravel how male, female mouse embryos acquire sex-specific reproductive systems

A protein called COUP-TFII determines whether a mouse embryo develops a male reproductive tract, according to researchers at the National Institutes of Health and their colleagues at Baylor College of Medicine, Houston.

Antibiotic use makes immune cells less effective in fighting infections

Adding another reason for doctors to avoid the overuse of antibiotics, new research shows that a reduction in the variety of microbes in the gut interferes with the immune system's ability to fight off disease.

Abnormal eating schedules affect skin’s protection from harmful UV rays of the sun

Sunbathers may want to avoid midnight snacks before catching some rays. A study in mice from the O'Donnell Brain Institute and UC Irvine shows that eating at abnormal times disrupts the biological clock of the skin, including the daytime potency of an enzyme that protects against the sun's harmful ultraviolet radiation.

Teenagers’ impulsive and risk taking behavior not related to brain deficit symptoms

A popular theory in recent neuroscience proposes that slow development of the prefrontal cortex - and its weak connectivity with brain reward regions - explains teenagers' seemingly impulsive and risky behavior.

Diet determines seizure latency: Estrogen production in the brain linked to omega-3 fatty acid intake

Scientists are increasingly appreciating estrogen's role in brain health. Now for the first time, production of estrogen in the brain has been directly linked to the presence of docosahexaenoic acid (DHA).

Artificial womb may provide avenue to improve outcomes for extremely preterm infants

An artificial womb has been successfully used to incubate healthy baby lambs for a period of one week, and researchers hope the technology will one day be able to do the same for extremely premature babies.

Research provides clues to how infectious bacteria may increase risk of cancer

Gastric carcinoma is one of the most common causes of cancer-related deaths, primarily because most patients present at an advanced stage of the disease.

Researchers identify role of blood-filtering organs in fighting against viral infections

New information about how and where the innate immune system fights off viral infections that enter through the skin could lead to better treatments for viruses like Zika, dengue and measles, according to Penn State College of Medicine researchers.

Novel blood test identifies tumor-derived DNA in early-stage cancer patients

In a bid to detect cancers early and in a noninvasive way, scientists at the Johns Hopkins Kimmel Cancer Center report they have developed a test that spots tiny amounts of cancer-specific DNA in blood and have used it to accurately identify more than half of 138 people with relatively early-stage colorectal, breast, lung and ovarian cancers.

Scientists use magnetic nanoparticles to trigger activity deep inside the brain

Scientists have used magnetism to activate tiny groups of cells in the brain, inducing bodily movements that include running, rotating and losing control of the extremities -- an achievement that could lead to advances in studying and treating neurological disease.

Impaired DNA replication may lead to trans-generational inheritance of epigenetic changes

Scientists reveal that a fault in the process that copies DNA during cell division can cause epigenetic changes that may be inherited for up-to five generations.

New synthetic antifreeze could make aeroplane wing design, organ transplants more effective

The design of aeroplane wings and storing organs for transplant could both become safer and more effective, thanks to a synthetic antifreeze which prevents the growth of ice crystals, developed by researchers at the University of Warwick.

Scientists discover novel therapeutic strategy to treat aggressive subgroup of lung cancer

Research conducted by a team of Norton Thoracic Institute scientists on a novel therapeutic avenue for an aggressive and difficult to treat subgroup of lung cancer was published in the August 15, 2017 issue of Cancer Research.

Researchers discover new brain area involved in spatial memory and navigation

Navigation in mammals including humans and rodents depends on specialized neural networks that encode the animal's location and trajectory in the environment, serving essentially as a GPS, findings that led to the 2014 Nobel Prize in Medicine.

New study aims to provide clarification on concurrent surgery of mitral and tricuspid valves

Insufficiency (leakage) of the mitral valve in the left side of the heart can also lead to tricuspid valve insufficiency in the right side of the heart.

Researchers discover way to stop deadly fungus from spreading to the brain

Research led by the University of Birmingham has discovered a way to stop a deadly fungus from 'hijacking' the body's immune system and spreading to the brain.

New noninvasive approach uses polarized light to help surgeons identify crucial nerves

During operations, it can be difficult for surgeons to avoid severing crucial nerves because they look so much like other tissue.

UC Irvine pharmacology researchers unearth potential roots of schizophrenia

An abundance of an amino acid called methionine, which is common in meat, cheese and beans, may provide new clues to the fetal brain development that can manifest in schizophrenia, University of California, Irvine pharmacology researchers report in the journal Molecular Psychiatry.

Scientists identify basic biological mechanism that kills neurons in ALS

A team led by scientists at St. Jude Children's Research Hospital and Mayo Clinic has identified a basic biological mechanism that kills neurons in amyotrophic lateral sclerosis (ALS) and in a related genetic disorder, frontotemporal dementia (FTD), found in some ALS patients.

Vaginal estrogens do not increase cancer, cardiovascular disease risk in post-menopausal women

Women who have gone through menopause and who have been using a vaginal form of estrogen therapy do not have a higher risk of cardiovascular disease and cancer than women who have not been using any type of estrogen.
