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.
Health officials battling the Ebola outbreak that has killed more than 4,500 people in West Africa have managed to limit its spread on the continent to five countries - and two of them appear to have snuffed out the disease.
Researchers have discovered that some scar-forming cells in the heart, known as fibroblasts, have the ability to become endothelial cells— the cells that form blood vessels. The finding could point the way toward a new strategy for treating people who have suffered a heart attack
Short-term modest weight gains in healthy, normal weight young adults was associated with more bad cholesterol levels in those who ate muffins cooked using saturated oil. However, individuals in the same study who ate muffins made with polyunsaturated oils had improved blood cholesterol profiles, according to a new study.
In acute asthma, various triggers, including viral illnesses and aeroallergens, can cause acute narrowing of the airways leading to a life-threatening respiratory crisis and sometimes death. Researchers have identified a novel factor that puts the brakes on airway smooth-muscle contraction relevant to asthma.
The brain has a complex system for keeping track of which direction you are facing as you move about; remembering how to get from one place to another would otherwise be impossible. Researchers have now shown how the brain anchors this mental compass.
The deadly Ebola virus has infected two people in what was the last untouched district in Sierra Leone, the government said Thursday, a setback in efforts to stop the spread of the disease in one of the hardest-hit countries.
As San Diego’s ViaCyte was in the midst of launching the first FDA-approved embryonic stem (ES) cell clinical trial for diabetics last week, Boston’s Harvard University reported that cells made from ES cells “cured” diabetic mice.
As Thomas Eric Duncan's health deteriorated, nurses Amber Joy Vinson and Nina Pham were at the Ebola patient's side. They wore protective gear as they inserted catheters, drew blood and dealt with his body fluids. Still, the two somehow contracted Ebola from the dying man.
How come nurses wearing protective gear can catch Ebola from a patient, but health officials keep saying you almost certainly won't get it from someone sitting next to you on a plane?
Researchers have found a way to kill prostate cancer cells by delivering a trove of copper along with a drug that selectively destroys the diseased cells brimming with the mineral, leaving non-cancer cells healthy.
Researchers have found vital new evidence on how to target and reverse the effects caused by one of the most common genetic causes of Parkinson’s.
Pancreatic cancer likely takes between 10 and 20 years to develop, providing the potential for a very “broad window” of intervention if detected early, which may be possible for people who inherit a predisposition, say researchers.
Using a recently developed biomarker of aging known as an epigenetic clock, researchers have found for the first time that obesity greatly accelerates aging of the liver.
Using ultrasound to deliver power wirelessly, researchers are working on a new generation of medical devices that would be planted deep inside the body to monitor illness, deliver therapies and relieve pain.
