A protein that stimulates the brain to awaken from sleep may be a target for preventing Alzheimer’s disease, according to a new study. In recent years, scientists have established links between sleep problems and Alzheimer’s.
Whether they want to or not, consumers will soon know how many calories they are eating when ordering off the menu at chain restaurants, picking up prepared foods at supermarkets and even eating a tub of popcorn at the movie theater.
Raw sprouts are linked to dozens of cases of food poisoning - again. The CDC said 63 people from 10 states concentrated on the East Coast fell ill with salmonella linked to bean sprouts.
Merck & Co., a top creator and seller of vaccines, has joined the fight against Ebola, the often-fatal hemorrhagic virus that's been ravaging parts of West Africa for months.
Guided by breakthrough research on the Estrogen Receptor 1 (ESR1) gene, many researchers and pharmaceutical companies are in hot pursuit of the next big anti-resistance breast cancer drug.
A research team has developed new computer games designed to significantly reduce the likelihood of falls at home and in the community among older people.
A new, enhanced MRI diagnostic approach was, for the first time, able to identify significant damage to the blood-brain barrier (BBB) of professional football players following “unreported” trauma or mild concussions.
Researchers had never shown exactly how cells in the brain stem detect carbon dioxide and regulate breathing in humans. After taking a mutation from a two-month-old baby and expressing it in human astrocytes, they did exactly that, and the research may lead to an early warning system to save premature infants.
A gene associated with schizophrenia plays a role in brain development and may help to explain the biological process of the disease, according to new research.
The next Ebola or the next SARS. Maybe even the next HIV. Even before the Ebola epidemic in West Africa is brought under control, public health officials are girding for the next health disaster.
A plague outbreak has killed 40 people on the island nation of Madagascar, with 119 people diagnosed with the bacterial disease since August. Two people have been diagnosed and one has died in the capital, Antananarivo.
University of Queensland scientists have discovered that genes switch off as memories are being formed, allowing for new connections between nerve cells. Read more...
Immunity is a thankless job. Though the army of cells known as the immune system continuously keeps us safe from a barrage of viruses, bacteria and even precancerous cells, we mainly notice it when something goes wrong: “Why did I get the flu this year even though I got vaccinated?” Read more...
Harvard Stem Cell Institute scientists at Brigham and Women’s Hospital say they have found the cellular origin of the tissue scarring caused by organ damage associated with diabetes, lung disease, high blood pressure, kidney disease, and other conditions. Read more...
Human existence is basically circadian. Most of us wake in the morning, sleep in the evening, and eat in between. Body temperature, metabolism, and hormone levels all fluctuate throughout the day, and it is increasingly clear that disruption of those cycles can lead to metabolic disease. Read more...
Using an ultrasensitive blood test to detect the presence of a protein that heralds heart muscle injury, researchers from Johns Hopkins and elsewhere have found that obese people without overt heart disease experience silent cardiac damage that fuels their risk for heart failure down the road. Read more...
Initial results of an innovative study may significantly change how some patients are evaluated after a stroke, according to researchers at Washington University School of Medicine in St. Louis. Read more...
An experimental 3-dimensional printed model of the heart may help surgeons treat patients born with complicated heart disorders, according to new research.
Researchers have pioneered a stem cell gene therapy cure for children born with adenosine deaminase (ADA)-deficient severe combined immunodeficiency (SCID), often called "Bubble Baby" disease.
They have been a scourge for thousands of years, responsible for the spread of lethal diseases such as malaria and dengue fever, and, much less urgently, a threat to barbecues around the globe. What if there was a way to render humans invisible to mosquitoes?
The spread of Ebola remains "intense" in most of Sierra Leone even as things have improved somewhat in the two other countries hardest hit, the World Health Organization says.
Research shows that taking a cholesterol-lowering drug for five years in middle age can lower heart and death risks for decades afterward. The benefits seem to grow over time and may last for life.
People with mental health problems are “significantly” more likely to have stroke or heart disease, according to a study unveiled at a recent Canadian Cardiovascular Congress.
In a new study, scientists found that a particular set of cells in a small region of the brain are responsible for memory problems after sleep loss. By selectively increasing levels of a signaling molecule in these cells, the researchers prevented mice from having memory deficits.
Blueberries are super stars among health food advocates, who tout the fruit for improving night vision. Scientists have now found reason to doubt that the popular berry helps most healthy people see better in the dark.
