Researchers have uncovered a brain pathway that shuts down seizures. They found that an acid-activated ion channel in the brain reacts to a drop in pH (increased acid) in a way that shuts down seizure activity. The link between low pH in the brain and seizure termination was first hinted at nearly 80 years ago […]
A team of medical, ethical and legal scholars argues in PLoS Medicine that in some US states the modification of lethal injection protocols is tantamount to experimentation upon prisoners without the prisoners’ consent and without any ethical safeguards.
A single organ may contain more than one type of adult stem cell — a discovery that complicates prospects for using the versatile cells to replace damaged tissue as a treatment for disease, according to a new study.
A new study says that cases of Amyotrophic Lateral Sclerosis among soldiers who served in the first Persian Gulf War were caused by certain events during their deployment to the war zone, meaning the exposure and illness is not as widespread as previously thought.
Morningness is a predictor of better grades in college. According to the results, college students who are evening types had lower GPAs, while those who are morning types had higher GPAs.
Amid recent reports of dangerous levels of arsenic being found in some baby rice products, scientists have found a protein in plants that could help to reduce the toxic content of crops grown in environments with high levels of this poisonous metal. A team of Scandinavian researchers has revealed a set of plant proteins that […]
Nearly half of all heart surgery patients may experience blood sugar levels high enough to require temporary insulin treatment after their operation, even though they’ve never had diabetes, according to a new study. And a significant minority of those patients might need to take medicines for days or even weeks after they leave the hospital, […]
The magnitude of circadian advantage influences the outcome of Major League Baseball games in that teams with greater circadian advantage are more likely to win. Crossing multiple time zones further reduces the probability of success for traveling teams.
Scientists have found a mechanism that allows cells starved of iron to shut down energy-making processes that depend on iron and use a less efficient pathway involving glucose. This metabolic reshuffling mechanism, found in yeast cells, helps explain how humans respond to iron deficiency, and may help with diabetes research as well.
A new inhalable form of gene therapy — based on technology recognized in the 2006 Nobel medicine prize, shows increasing promise for treating lung cancer, infectious diseases and inflammatory lung disease, scientists have concluded after an exhaustive review of worldwide research on the topic.
