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.
For more than two months, health officials have been struggling to understand the size of a national wave of severe respiratory illnesses caused by an unusual virus. This week, they expect the wave to start looking a whole lot bigger.
A Dallas nurse being treated for Ebola has received a plasma transfusion from a doctor who beat his own infection with the deadly virus after getting a similar treatment. The reason: Antibodies in the blood of a survivor may help a patient fight off the germ.
The second health care worker diagnosed with Ebola in Texas is a 29-year-old nurse who treated the Liberian man who died of the disease in a Dallas hospital.
Lethal fibrosis in lungs of mice with idiopathic pulmonary fibrosis (IPF) can be reversed, say researchers. No drug on the market can do this. But the crew pulled it off, in mice, by temporarily restoring (a mimic of) one of the body’s own anti-fibrosis agents, sharply reduced in IPF: microRNA-29.
West Africa could face up to 10,000 new Ebola cases a week within two months, the World Health Organization warned Tuesday, adding that the death rate in the current outbreak has risen to 70 percent.
A new study shows that physical activity can improve memory performance in older people through increasing volume and blood flow in an area of the brain called hippocampus.
Injuries to six brain areas are much more devastating to patients’ abilities to think and adapt to everyday challenges than damage to other parts of the brain, scientists have learned.
A new study suggests a cause of amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig’s disease. The study provides evidence that those proteins linked to more severe forms of the disease are less stable structurally and more prone to form clusters or aggregates.
Researchers have known for decades that stress contributes to heart disease. But a new analysis shows mental stress may tax women’s hearts more than men’s.
The discovery of a cellular snooze button has allowed a team of scientists to potentially improve biofuel production and offer insight on the early stages of cancer.
Results of a small clinical trial suggest that a chemical derived from broccoli sprouts— and best known for claims that it can help prevent certain cancers— may ease classic behavioral symptoms in those with autism spectrum disorders (ASDs).
