An international group of 253 scientists has conducted one of the largest genetic studies to date and identified 74 genetic variants that are associated with the years of formal education that an individual completes.
For decades, pregnant women and women who may become pregnant have been advised to take folic acid to help prevent certain birth defects. But a new study suggests it may be possible to get too much of a good thing - very high levels of the vitamin in mothers' blood at the time of childbirth was linked to higher risk of their children developing autism years later.
Scientists are peeking inside living brains to watch for the first time as a toxic duo of plaques and tangles interact to drive Alzheimer's disease - and those tangles may predict early symptoms, a finding with implications for better treatments.
For millions of Americans at risk for blood clots, strokes and hypertension, routine lab tests to monitor blood-thinning medications can be frequent, costly and painful. But researchers are developing materials and technology for a simple in-home screening that could be a game changer for patients with several life-threatening conditions.
We know that changes in our genetic code can be associated with an increased risk for psychiatric illnesses such as schizophrenia and bipolar disorder. But how can a genetic mutation lead to complex psychiatric symptoms such as vivid hallucinations, manic episodes and bizarre delusions?
Scientists have uncovered the secret of the 'Mona Lisa of chemical reactions' - in a bacterium that lives at the bottom of the Pacific Ocean. It is hoped the discovery could lead to the development of new antibiotics and other medical treatments.
One of the hurdles of realizing the promise of nanoparticles is that scientists can’t view where they go or how the nanoparticles interact with structures once they are inside of the body. A new technique seeks to overcome that challenge.
In a new study researchers from Harvard-affiliated Brigham and Women’s Hospital find a connection between gut bacteria and the activity of cells in the brain that influence inflammation and neurodegeneration.
The new Zika Virus Envelope (E) Protein Antibody from Kerafast, Inc. is a human serum specimen containing polyclonal antibodies induced by natural infection with the Zika virus.
Signaling a potential new approach to treating diabetes, researchers have produced insulin-secreting cells from stem cells derived from patients with type 1 diabetes.
To study certain aspects of cells, researchers need the ability to take the innards out, manipulate them, and put them back. Options for this kind of work are limited, but researchers describe a 'nanoblade' that can slice through a cell's membrane to insert mitochondria.
By combining information on gene-disease associations with maps of chemical modifications known as epigenomic marks, which control what genes are turned on, researchers were able to identify additional genetic contributors to a heritable cardiac disorder that makes people more susceptible to heart failure. This strategy could also shed light on many other inherited diseases.
A urine-based test for Zika virus infection has shown to be more effective than the common blood-based one for many patients, a development that could make testing for the infection easier.
Chronic use of some drugs for heartburn and gastroesophageal reflux (GERD) speeds up the aging of blood vessels, according to a new paper. This accelerated aging in humans could lead to increased cardiovascular disease, vascular dementia and renal failure.
A team of scientists is expanding web services to make biomedical research more efficient. With their free, public projects, MyGene.info and MyVariant.info, researchers around the world have a faster way to spot new connections between genes and disease.
