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).
A research team has used high-resolution cryo-electron microscopy to obtain novel insights into the ultrastructural changes in an intracellular machine associated with the acquisition of resistance to the antibiotic erythromycin.
Scientists discovered an immune protein with paradoxical roles: It both aids and tamps down aspects of an immune system response, according to new research.
For many years, the focus of brain mapping was to examine changes in the brain that occur when people are attentively engaged in an activity. No one spent much time thinking about what happens to the brain when people are doing very little. But new research has done just that.
Scientists report that newly formed brain cells in the mouse olfactory system— the area that processes smells— play a critical role in maintaining proper connections.
For many patients diagnosed with diabetes, treating the disease can mean a burdensome and uncomfortable lifelong routine of monitoring blood sugar levels and injecting the insulin that their bodies don't naturally produce. Now, tiny biosensors are being developed that could one day eliminate the need for these manual blood sugar tests.
The World Health Organization called the Ebola outbreak "the most severe, acute health emergency seen in modern times" on Monday but also said that economic disruptions can be curbed if people are adequately informed to prevent irrational moves to dodge infection.
A breach of infection control resulting in a Dallas health worker getting Ebola raises fresh questions about whether hospitals truly can safely take care of people with the deadly virus, as health officials insist is possible.
Oxytocin, the body’s natural love potion, helps couples fall in love, makes mothers bond with their babies, and encourages teams to work together. Now, new research reveals a mechanism by which this prosocial hormone has its effect on interactions between the sexes, at least in certain situations. The key is a newly discovered class of brain cells.
People with autism spectrum disorder often experience a period of accelerated brain growth after birth. No one knows why, or whether the change is linked to any specific behavioral changes. A new mouse study demonstrates how inflammation can trigger an excessive division of neural stem cells that can cause “overgrowth” in offspring’s brain.
Just look into the light: not quite, but researchers have used light to erase specific memories in mice, and proved a basic theory of how different parts of the brain work together to retrieve episodic memories.
Researchers have established how two degenerative diseases that present in similar ways are in fact quite different. Progressive Supranuclear palsy (PSP) and Parkinson’s disease (PD) have overlapping symptoms but remain difficult to distinguish.
A previously unknown mechanism through which the brain produces new nerve cells after a stroke has been discovered. The researchers have shown that following an induced stroke in mice, support cells, so-called astrocytes, start to form nerve cells in the injured part of the brain.
In rare cases, patients with allergies to metals develop persistent skin rashes after metal devices are implanted near the skin. New research suggests these patients may be at increased risk of an unusual and aggressive form of skin cancer.
Scientists have discovered a new class of molecules– produced in human and mouse fat– that protects against diabetes. The researchers found that giving this new fat to mice with the equivalent of type 2 diabetes lowered their elevated blood sugar.
The first study of a possible Ebola vaccine is underway in Africa: University of Maryland researchers say three health care workers in Mali received the experimental shots.
