Longer shifts do not create chronic sleep loss in first-year doctors or reduce safety for patients, study finds — ScienceDaily

When medical residents were permitted to work shifts longer than 16 hours, patient mortality was not affected and the doctors themselves did not experience chronic sleep loss, according to a pair of papers published today in the New England Journal of Medicine by a team of researchers from the Perelman School of Medicine at the…

Clinical trial shows reduction of inflammation in humans; diet appears to reverse Crohn’s and colitis pathology in mice — ScienceDaily

USC researchers provided evidence that a low-calorie “fasting-mimicking” diet has the potential to do just that. Published in the March 5 edition of Cell Reports, the study reports on the health benefits of periodic cycles of the diet for people with inflammation and indicated that the diet reversed inflammatory bowel disease (IBD) pathology in mice.…

Study upends ideas inferred from nonwoody plants — ScienceDaily

North Carolina State University researchers have uncovered how a complex network of transcription factors switch wood formation genes on and off. Understanding this transcriptional regulatory network has applications for modifying wood properties for timber, paper and biofuels, as well as making forest trees more disease- and pest-resistant. “We’re building a complete story, so to speak,…

Sensory tests suggest ‘liking’ wines made with native grapes a learned response — ScienceDaily

Consumer preference or aversion to wines made from native grapes — such as Concord, Niagara and Catawba, which are grown in North America — may depend on early exposure to the fruits’ sweet, ultra “grapey” taste and aroma, according to researchers who conducted sensory tests with wine drinkers in Pennsylvania and California. That strong grapey…

Culturally sensitive conservation approaches needed to protect Ethiopian church forests — ScienceDaily

Human disturbance reduces forest density, biomass, and richness of species in sacred church forests of northern Ethiopia, according to new research by Catherine L. Cardelús of Colgate University in Hamilton, NY, and colleagues. These findings appear in PLOS ONE. Due to land-use changes, such as roads and agriculture, forested area that once covered much of…

Alternative to anti-inflammatory therapies reduces IBD symptoms in mice — ScienceDaily

People with inflammatory bowel disease (IBD) live with frequent, miserable episodes of abdominal pain, diarrhea and in severe cases, rectal bleeding. Standard treatments are aimed at directly suppressing inflammation, but many patients find little relief from such an approach. Now, researchers at Washington University School of Medicine in St. Louis have found a compound that…

New insights into the geographical landscape of prehistoric central Tibet — ScienceDaily

A team of scientists from the UK and China have uncovered new evidence, using recently-discovered 25-million-year-old fossilised palm leaves, that Tibet’s geography was not as ‘high and dry’ as previously thought. The new research, co-authored by academics from the University of Bristol’s School of Geographical Sciences, suggests that central Tibet must have been no higher…
