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).
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.
A team of scientists and engineers developed a new surface coating for medical devices using materials already approved by the Food and Drug Administration (FDA). The coating repelled blood from more than 20 medically relevant substrates the team tested.
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.
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.
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.
