Brain tumor growth stimulated by nerve activity in the cortex, study finds
New research shows that high-grade gliomas, the deadliest human brain tumors, increase their growth by hijacking some of the machinery of neuroplasticity, which normally helps the brain form new synapses.
Patient-doctor ethnic differences thwart conversations on end-of-life care, study finds
Doctors struggle to start discussions with ailing patients about how they want to spend their last days, a survey finds. The upshot? Patients should bring up the topic themselves.
Viral proteins may regulate human embryonic development
Human embryos make viral proteins within days of fertilization, a new study shows. These proteins affect human gene expression and may protect the cells from infection by other viruses.
Karl Deisseroth wins prestigious Albany Prize
The bioengineer and psychiatrist will be honored for his seminal role in the field of optogenetics, which allows scientists to precisely manipulate nerve-cell activity in freely moving animals to study their behavior.
Cell type responsible for scarring, skin-cancer growth identified
A single cell type in the skin of mice is a major contributor to scarring after wound healing or radiation damage, and facilitates the growth of melanoma. Blocking the cell’s activity in humans may be possible with currently approved drugs.
Encountering a wall corrects 'GPS' cells in mouse brains, study finds
Researchers have found more evidence that the brain’s grid cells help a mouse mentally map its location.
Adherence to blood thinner best with pharmacist management, researcher says
Researchers found that adherence to a new-generation anticoagulant, used to prevent stroke in heart disease patients, is best at sites with pharmacist-led management.
Recruiting patients for research? Simple explanations, queries from doctors are best
Patients want to be asked permission to participate in research that compares standard treatment options and that involves reviews of medical records, according to a new study.
Study deciphers the noise in the human brain
Electrical recordings directly from the human brain show remarkable precision in the coordination of widely distributed regions involved in memory recall, at rest and during sleep.
Stanford-led study finds few mutations involved in transmission of drug-resistant HIV
A multicenter study has found that a small group of mutations accounted for a majority of the cases of transmission-related resistance to HIV drugs used to treat infections in developing countries…
Leading the Biomedical Revolution
We are in the middle of a biomedical revolution more profound and far-reaching than the industrial and digital revolutions that made it possible.
