There’s a reason so many children are prescribed methylphenidate, better known by the trade name Ritalin: it helps kids quell attention and hyperactivity problems and sit still enough to focus on a school lesson. The drug keeps more of the neurotransmitter dopamine loose among brain cells, enhancing cell-to-cell transmission of […]

Neurons in the brain and spinal cord don’t grow back after injury, unlike those in the rest of the body. Cut your finger, and you’ll probably be back to using it in days or weeks; slice through your spinal cord, and you likely will never walk again. Now, working in […]

Researchers have identified another reason to limit red meat consumption: high levels of a gut-generated chemical called trimethylamine N-oxide (TMAO), that also is linked to heart disease. Scientists found that people who eat a diet rich in red meat have triple the TMAO levels of those who eat a diet […]

African-Americans with moderate or severe sleep apnea are twice as likely to have hard-to-control high blood pressure when their sleep apnea goes untreated, according to a new study funded mainly by the National Heart, Lung, and Blood Institute (NHLBI), part of the National Institutes of Health. The findings, which researchers […]

It’s a simple message, but as screening recommendations for colorectal and other cancers become more complicated, what happens when the message becomes “maybe get screened” or even “stop screening”? A new study in JAMA Network Open finds nearly one-third of veterans who underwent recommended screening colonoscopies were uncomfortable with the idea of […]

Genetics may play a larger role in pancreatic cancer than previously thought, an expert panel has found. It’s led to the American Society of Clinical Oncology recommending that genetic testing be offered to anyone diagnosed with pancreatic cancer. The goal: to help identify family members who might be at greater risk. “It […]

A new computational model developed by researchers from The City College of New York and Yale gives a clearer picture of the structure and mechanics of soft, shape-changing cells that could provide a better understanding of cancerous tumor growth, wound healing, and embryonic development. Mark D. Shattuck, professor of physics at City […]

An insulin injection can manage diabetes symptoms, but actually curing the disease would mean healing cells in the pancreas that produce insulin, a hormone that regulates the amount of sugar in blood. One promising approach may be to stimulate the regeneration of those cells with drugs. But there’s a major […]

Millions of people in the United States alone have submitted their DNA for analysis and received information that not only predicts their risk for disease but, it turns out, in some cases might also have influenced that risk, according to a recent study by researchers at Stanford University. The team, […]

Like Zika, infection with Rift Valley fever virus can go unnoticed during pregnancy, all the while doing irreparable – often lethal – harm to the fetus. The results of a new study, led by researchers at the University of Pittsburgh Center for Vaccine Research (CVR), underscore the importance of disease prevention for […]

How does cancer spread? While studying human brain tumour cells, a team of scientists at the Research Institute of the McGill University Health Centre (RI-MUHC) found some answers to this crucial, yet so far unanswered question. They looked at a gene called EGFRvIII, which is present in patients with glioblastoma – […]

The neurodegenerative disease ALS causes motor neuron death and paralysis. However, long before the cells die, they lose contact with the muscles as their axons atrophy. Researchers at Karolinska Institutet have now devised a new method that radically improves the ability to study axons and thus to better understand the […]
