Type 1 diabetes affects 46.3 million people worldwide, and the number of people affected increases by about 3% each year. It requires careful calculations of insulin needs and bothersome daily injections to avoid peripheral diseases caused by extremes of high or low blood sugar. Automated insulin delivery systems, also called artificial pancreases, make diabetes management […]
Researchers at UC Santa Barbara identified the pathway in fruit flies that reduces the sensation of pain from heat. Remarkably, just a single neuron on each side of the animal’s brain controls the response. What’s more, the molecule responsible for suppressing this sensation in adult flies has the opposite role in fly larvae. The surprising […]
Both cluster headache and migraine have strong links to the circadian system, the internal clock that regulates body processes, according to a meta-analysis. “The data suggest that both of these headache disorders are highly circadian at multiple levels, especially cluster headache,” said study author Mark Joseph Burish, MD, PhD. “This reinforces the importance of the […]
A new study shines a light on the role of spindles in alleviating anxiety in PTSD as well as confirms their established role in the transfer of new information to longer-term memory storage. “These findings may be meaningful not only for people with PTSD, but possibly for those with anxiety disorders,” said senior author Anne […]
Bacteria can rapidly evolve resistance to antibiotics by adapting special pumps to flush them out of their cells, according to new research from the Quadram Institute and University of East Anglia. Antimicrobial resistance is a growing problem of global significance. The rise of resistant “superbugs” threatens our ability to use antimicrobials like antibiotics to treat […]
Watching the clock while trying to fall asleep exacerbates insomnia and the use of sleep aids, according to research from an Indiana University professor — and a small change could help people sleep better. The research, led by Spencer Dawson, clinical assistant professor and associate director of clinical training in the College of Arts and […]
Have you ever wondered why some people might get sicker than others, even when they catch the same virus?. A number of host factors have been considered, including pre-existing immunity, age, sex, weight, and the microbiome. Another important factor is the molecular biology within your cells. DNA is shown as one long double-helical strand. So, […]
The research, led by Spencer Dawson, clinical assistant professor and associate director of clinical training in the College of Arts and Sciences’ Department of Psychological and Brain Sciences, focuses on a sample of nearly 5,000 patients presenting for care at a sleep clinic. Participants completed questionnaires about the severity of their insomnia, their use of […]
Researchers at UCLA Health and Harvard have identified 10 pesticides that significantly damaged neurons implicated in the development of Parkinson’s disease, providing new clues about environmental toxins’ role in the disease. While environmental factors such as pesticide exposure have long been linked to Parkinson’s, it has been harder to pinpoint which pesticides may raise risk […]
Researchers at the University of Michigan Rogel Cancer Center have discovered a new nutrient source that pancreatic cancer cells use to grow. The molecule, uridine, offers insight into both biochemical processes and possible therapeutic pathways. The findings, published in Nature, show that cancer cells can adapt when they don’t have access to glucose. Researchers have […]
