Using an innovative exome sequencing strategy, a team of international scientists has shown that TUBA4A, the gene encoding the Tubulin Alpha 4A protein, is associated with familial amyotrophic lateral sclerosis (ALS).
Stem cell therapies are being hailed as a potential cure for many major health conditions, but there is much still to learn about the highly complex environments needed to optimize these therapies, according to new research.
Researchers have identified an unusual process by which the body can sense the presence of pathogenic bacteria and destroy them. Rather than detect the microbes directly, individual cells monitor how the bacteria interfere with the functioning of energy-producing cellular structures called mitochondria.
Researchers now developed a new way to model the effects of these genetic mutations in mice. The approach, based on the genome-editing technique known as CRISPR, is much faster than existing strategies, which require genetically engineering mice that carry the cancerous mutations.
Combining a PET scanner with a new chemical tracer that selectively tags specific types of bacteria, researchers working with mice report they have devised a way to detect and monitor in real time infections with a class of dangerous Gram-negative bacteria.
All travelers who come into the U.S. from three Ebola-stricken West African nations will now be monitored for three weeks, the latest step by federal officials to keep the disease from spreading into the country.
The Bertarelli Program in Translational Neuroscience and Neuroengineering, a collaborative program between Harvard Medical School and the École Polytechnique Fédérale de Lausanne (EPFL) in Switzerland, has announced a new set of grants worth $3.6 million for five research projects.
Children with autism spectrum disorder (ASD) were more likely to have been exposed to higher levels of certain air toxics during their mothers’ pregnancies and the first two years of life compared to children without the condition, according to a new study.
Before dunking your favorite food in a vat of just any old oil, consider using olive. Scientists are reporting that olive oil withstands the heat of the fryer or pan better than several seed oils to yield more healthful food.
Drawing blood and testing it is standard practice for many medical diagnostics. As a less painful alternative, scientists are developing skin patches that could one day replace the syringe.
Researchers have pinpointed a set of intriguing characteristics in a previously unknown subpopulation of melanoma cancer cells in blood vessels of tumors.
Researchers are facing increasing demands from colleagues, peers and publishers for process documentation including adequate controls, and for extensive documentation of experimental parameters. Without such consideration, there would be little chance to repeat, or even validate, findings.
A top Red Cross official says he is confident the Ebola epidemic can be contained within four to six months. The Ebola outbreak has killed more than 4,500 people since it emerged 10 months ago, with Liberia, Guinea and Sierra Leone the worst-affected countries.
Scientists have uncovered details about how cancer is able to become drug resistant over time, a phenomenon that occurs because cancer cells within the same tumor aren’t identical.
Developing invisible implantable medical sensor arrays, a team of engineers has overcome a major technological hurdle in researchers’ efforts to understand the brain.
Researchers have created a cellular probe that combines a tarantula toxin with a fluorescent compound to help scientists observe electrical activity in neurons and other cells.
Mitochondrial oscillations have quietly bewildered scientists for more than 40 years. Now, a team of scientists has imaged mitochondria for the first time oscillating in a live animal, in this case, the salivary glands of laboratory rats.
Supplementing current anti-depressant medication with B vitamins improves response to treatment, according to a new study.
People who shared an apartment with the country's first Ebola patient are emerging from quarantine healthy. And while Thomas Eric Duncan died and two U.S. nurses were infected caring for him, there are successes, too: A nurse infected in Spain has recovered, as have four American aid workers infected in West Africa. Even there, not everyone dies.
Health officials have released new guidelines for how health workers should gear up to treat Ebola patients. The Centers for Disease Control and Prevention released the long-anticipated updates on Monday evening.
Water laced with salt and sugar, and gallons of the nasty-tasting stuff. Doctors who survived Ebola in Nigeria credited heavy doses of fluids with saving their lives as the Who declared the country Ebola-free Monday.
Ever wondered how people figure out what is fair? Look to the brain for the answer. According to a new study, people appreciate fairness in much the same way as they appreciate money for themselves, and also that fairness is not necessarily that everybody gets the same income.
Getting enough magnesium in the diet may reduce the risk of diabetes, especially for those who already show signs of heading that way, according to a new study.
A group of scholars issued a statement skeptical about the effectiveness of so-called "brain game" products, citing that the scientific track record does not support the claims that these games actually help older adults boost their mental powers.
A drug being studied as a fast-acting mood-lifter restored pleasure-seeking behavior independent of— and ahead of— its other antidepressant effects, in an NIH trial.
