New research in an animal model suggests a high-fat diet during pregnancy alters the development of the brain and endocrine system of offspring. The new study links an unhealthy diet during pregnancy to mental health disorders such as anxiety and depression in children.
In saliva, scientists have found hints that a 'ghost' species of archaic humans may have contributed genetic material to ancestors of people living in sub-Saharan Africa today. The research adds to a growing body of evidence suggesting that sexual rendezvous between different archaic human species may not have been unusual.
Offering $100 to patients eligible for a preventive colonoscopy screening more than doubled the rate of screening when compared to a simple emailed request, according to new research from the Perelman School of Medicine at the University of Pennsylvania.
A team of Wayne State University researchers recently received a $1.9 million grant from the National Eye Institute of the National Institutes of Health to better understand leukodystrophies (LD) and genetic Leukoencephalopathies (gLE), rare genetic disorders affecting the white matter -- myelin -- in the central nervous system. Patients diagnosed with a leukodystrophy experience a gradual decline in development, including a progressive loss in gait, body tone, vision, hearing, swallowing and/or ability to eat.
People who carry a genetic susceptibility to Alzheimer's disease appear to be at greater risk of diminished cognition from sleep-disordered breathing than those without the susceptibility, according to new research published online, ahead of print in the Annals of the American Thoracic Society.
A cooperative research team led by researchers at Dartmouth's Norris Cotton Cancer Center devised a strategy to target cancer cells while sparing normal cells by capitalizing on vulnerabilities that are exposed only in tumor cells. These vulnerabilities are known as the 'Achilles heel' of cancer cells. Although much is known about the mutations that cause a cell to become malignant, little is known about these vulnerabilities. The team has published new findings on this topic.
Northwestern University neuroscientists now can visualize how fruit flies sense and process humidity and temperature together through a 'sensory map' within their brains, according to new research. The findings could one day help researchers better understand how the human brain simultaneously processes humidity and temperature and might influence how humans control for mosquitoes in cities and prevent mosquito-borne diseases.
As outlined in a study published today in Nature, lead author Devin Sok, Director, Antibody Discovery and Development at the International AIDS Vaccine Initiative (IAVI), reports the elicitation of powerful, HIV-blocking antibodies in cows in a matter of weeks -- a process that usually takes years in humans. The unexpected animal model is providing clues for important questions at a moment when new energy has infused HIV vaccine research.
New research provides insight into how changes that occur with age may predispose breast tissue cells to becoming cancerous. Specifically, the study demonstrates that regions in the genome where DNA methylation changes occur with age are particularly sensitive to disruption in cancer. This new data provides insight into how certain molecular changes with age in normal breast tissue itself may contribute to breast cancer risk.
Irregular heartbeat -- or arrhythmia -- can have sudden and often fatal consequences. A biomedical engineering team at Washington University in St. Louis examining molecular behavior in cardiac tissue recently made a surprising discovery that could someday impact treatment of the life-threatening condition.
