Enzyme in blood of young mice slows aging in older ones

(Julia Evangelou Strait-Wustl/ Futurity) — Scientists have discovered a potential way to stave off the detrimental effects of aging, according to their research in mice. The study suggests that a protein that is abundant in the blood of young mice plays a vital role in keeping them healthy. With age, levels of this protein decline […]

AI beats radiologists for accuracy in lung cancer screening

(Roxanne Nelson, RN, BSN/ Medscape) — Lung cancer screening using low-dose computed tomography (LDCT) is now recommended for certain populations, and while it has been shown to reduce mortality, there are persistent challenges with this technology, including inter-grader variability and high rates of false-positive and false-negative results. Artificial intelligence (AI) may be able to help […]

Study reveals how general anesthetics affect the brain

(Catharine Paddock/ Medical News Today) — New research in mice reveals for the first time that diverse drugs that induce general anesthesia activate a brain circuit that brings on sleep. The scientists at Duke University in Durham, NC who carried out the study, suggest that the findings will help to develop better drugs that can […]

How artificial intelligence helps in health care

(Lauren Paige Kennedy/ WebMD) — When many of us hear the term “artificial intelligence” (AI), we imagine robots doing our jobs, rendering people obsolete. And, since AI-driven computers are programmed to make decisions with little human intervention, some wonder if machines will soon make the difficult decisions we now entrust to our doctors. According to […]

Noninvasive brain stimulation turns back clock on memory

(Jed Akst/ The Scientist) — Noninvasive stimulation of key brain regions could help people reverse the common age-related decline in working memory — our ability to remember names, numbers, and other tidbits of information — according to a study published in Nature Neuroscience April 8. The approach, known as transcranial alternating current stimulation (tACS), allowed […]

AI can predict an abnormal chest X-ray

(Jennifer Kite-Powell/ Forbes) — New research from WMG at the University of Warwick in the United Kingdom shows that artificial intelligence (AI) can reduce the time needed to process abnormal chest x-rays and prioritize which x-rays need to be expedited. The research was led by Professor Giovanni Montana, Chair in Data Science in WMG at Warwick […]
