Using data from over 18,000 patients, scientists have identified more than two dozen genetic...
In a massive effort to catalog the molecular causes of stomach cancer, scientists have...
A new study has found that turning the thermostat down a few notches at night may expand brown fat tissue mass and activity, which could lead to metabolic benefits such as more effective disposal of glucose.
Nigerian health authorities raced to stop the spread of Ebola on Saturday after a man sick with one of the world's deadliest diseases brought it by plane to Lagos, Africa's largest city with 21 million people.
When it comes to preventing the spread of germs, maybe the president is on to something with his fondness for fist bumps. The familiar knocking of knuckles spreads only one-twentieth the amount of bacteria that a handshake does, researchers report.
Exposure to light at night, which shuts off nighttime production of the hormone melatonin, renders breast cancer completely resistant to tamoxifen, a widely used breast cancer drug, says a new study by Tulane University School of Medicine cancer researchers.
The European Society for Medical Oncology (ESMO) has expressed concern that the proposed EU General Data Protection Regulation could make cancer research impossible and add a significant burden to both doctors and cancer patients.
One strategy for developing a highly effective HIV vaccine is to learn how some HIV-infected people naturally develop antibodies that can stop a high percentage of global HIV strains from infecting human cells in the laboratory. These so-called broadly neutralizing antibodies (bNAbs) develop too late to help infected people overcome the virus.
The popular culinary herbs oregano and rosemary are packed with healthful compounds, and now lab tests show they could work in much the same way as prescription anti-diabetic medication, scientists report. In their new study, they found that how the herbs are grown makes a difference, and they also identified which compounds contribute the most to this promising trait.
Fragile X syndrome (FXS) is a genetic disorder that causes obsessive-compulsive and repetitive behaviors, and other behaviors on the autistic spectrum, as well as cognitive deficits. It is the most common inherited cause of mental impairment and the most common cause of autism. Now biomedical scientists at the University of California, Riverside have published a study that sheds light on the cause of autistic behaviors in FXS.
Parents, turn off the television when your children are with you. And when you do let them watch, make sure the programs stimulate their interest in learning. At least, that's the advice arising from researchers who examined the impact of television and parenting on children’s social and emotional development.
When a person experiences a devastating loss or tragic event, why does every detail seem burned into memory whereas a host of positive experiences simply fade away? It’s a bit more complicated than scientists originally thought, according to a study.
A nine-day quarantine imposed on parts of a northern Chinese city where a man there died of bubonic plague has been lifted, China's official news agency reported Thursday.
Health officials say that the head of the government lab which potentially exposed workers to live anthrax has resigned. Michael Farrell was head of the Centers for Disease Control and Prevention lab since 2009.
In a new study, a team of researchers has found evidence for a factor that contributes to adults’ language difficulties: When learning certain elements of language, adults’ more highly developed cognitive skills actually get in the way.
On this episode of Bioscience Technology This Week, Editor-in-Chief Rob Fee reports on research claiming that the sense of smell is linked to Alzheimer's Disease development. Our second story examines a new process that could aid cells in gobbling up undesirable neighbors.
People with Type 2 diabetes have an excess of a protein called islet amyloid polypeptide, or IAPP, and the accumulation of this protein is linked to the loss of insulin-producing pancreatic beta cells. Now, a team of researchers may have found a solution in autophagy, a process that clears damaged and toxic proteins from cell.
A probiotic that prevents obesity could be on the horizon. Bacteria that produce a therapeutic compound in the gut inhibit weight gain, insulin resistance and other adverse effects of a high-fat diet in mice, Vanderbilt University investigators have discovered.
Researchers of the Max Planck Institute of Molecular Cell Biology and Genetics in Dresden report how they managed to capture detailed three-dimensional images of cardiac dynamics in zebrafish. The novel approach: They combine high-speed Selective Plane Illumination Microscopy (SPIM) and clever image processing to reconstruct multi-view movie stacks of the beating heart.
Scientists have linked more than 100 spots in our DNA to the risk of developing schizophrenia, casting light on the mystery of what makes the disease tick. Such work could eventually point to new treatments, although they are many years away.
Parts of a northern Chinese city have been quarantined after state media said a man there died of bubonic plague. The Chinese news agency Xinhua said Tuesday that 151 people were under observation in the city of Yumen in Gansu province after authorities determined they had come in contact with a man who had died of the plague July 16.
The seriousness of disease often results from the strength of immune response, rather than with the virus, itself. Turning down that response, rather than attacking the virus, might be a better way to reduce that severity. Researchers have taken the first step in doing that for the H7N9 influenza, and their work has led to identification of six potential therapeutics for this highly virulent strain.
Viruses designed to target and kill cancer cells could boost the effectiveness of chemotherapy to the arms and legs and help avoid amputation. Scientists tested the effectiveness of a genetically engineered version of the virus used to vaccinate against smallpox. They found use of the virus alongside isolated limb perfusion chemotherapy was more effective in rats than either treatment on its own.
Teachers-in-training have long been taught that the fourth grade is when students stop learning to read and start reading to learn. But a new study tested the theory by analyzing brain waves and found that fourth-graders do not experience a change in automatic word processing. Instead, some types of word processing become automatic before fourth grade, while others don’t switch until after fifth.
Many bacteria swim using flagella, corkscrew-like appendages that push or pull bacterial cells like propellers. It had been assumed that the flagella do all the work during swimming, while the rest of the cell body is just along for the ride. But new research shows that in at least one species, the cell body is actively carving out a helical trajectory through the water that produces thrust and contributes to the organism's ability to swim.
The HIV-1 virus has proved to be tenacious, inserting its genome permanently into its victims' DNA, forcing patients to take a lifelong drug regimen to control the virus and prevent a fresh attack. Now, a team of Temple University School of Medicine researchers has designed a way to snip out the integrated HIV-1 genes for good.
Eating probiotics regularly may modestly improve your blood pressure, according to new research. Probiotics are live microorganisms (naturally occurring bacteria in the gut) thought to have beneficial effects; common sources are yogurt or dietary supplements.
