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.
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.
Alzheimer's disease is the most common among the dementia diseases. In recent years research has increasingly indicated that there is a possible connection between the two. Now, two new studies are supporting this link.
Researchers have successfully transplanted “organoids” of functioning human intestinal tissue grown from pluripotent stem cells in a lab dish into mice– creating an unprecedented model for studying diseases of the intestine.
Revised guidance for health care workers treating Ebola patients will include using protective gear "with no skin showing," a top federal health official said Sunday, and the Pentagon announced it was forming a team to assist medical staff in the U.S., if needed.
The World Health Organization declared on Monday that Nigeria is free of Ebola, a rare victory in the months-long battle against the fatal disease. Nigeria's containment of the lethal disease is considered a "spectacular success story."
New evidence of myelin’s essential role in learning and retaining new practical skills, such as playing a musical instrument, has been uncovered by researchers.
Sugar-sweetened soda consumption might promote disease independently from its role in obesity, according to a new study that found drinking sugary drinks was associated with cell aging.
Common viral infections can pave the way to autoimmune disease, scientists have revealed in breakthrough new research, which proved a link between the two.
The seemingly miraculous power of babies’ hearts to repair themselves after being injured has spurred a research team to investigate if this ability can be harnessed for new heart attack treatments.
Scientists have made a surprising finding about the aggregates of misfolded cellular proteins that have been linked to aging-related disorders such as Parkinson’s disease.
In a draft document, the World Health Organization has acknowledged that it botched attempts to stop the now-spiraling Ebola outbreak in West Africa, blaming factors including incompetent staff and a lack of information.
