Limiting first-year medical residents to 16-hour work shifts, compared to “flexing” them to allow for some longer shifts, generally makes residents more satisfied with their training and work-life balance, but their training directors more dissatisfied with curtailed educational opportunities. That’s one conclusion of a new study published online March 20 in the New England Journal of Medicine.

From floral perfume to fruity body wash and shampoos, scents heavily influence consumer purchases. But for most, the smell doesn’t last long after showering before it fades away. Scientists have now developed a way to get those fragrances to stick to the skin longer instead of washing down the drain immediately after being applied.

New research from a UC Santa Cruz Genomics Institute-affiliated team from the Jack Baskin School of Engineering just published in the journal Nature Biotechnology attempts to close huge gaps in our genomic reference map. The research uses nanopore long-read sequencing to generate the first complete and accurate linear map of a human Y chromosome centromere. This milestone in human genetics and genomics signals that scientists are finally entering a technological phase when completing the human genome will be a reality.

Every year, approximately 12 million adults in the U.S. are diagnosed with Chronic Obstructive Pulmonary Disease, and 120,000 die from it. For people with COPD, Haemophilus influenzae, a bacterium, can be particularly dangerous. Now, researchers have unraveled how the bacterium adapts quickly, which may open new avenues for therapy for COPD and other diseases such as ear infections or pneumonia.

Reproductive hormones that develop during puberty are not responsible for changes in social behavior that occur during adolescence, according to the results of a newly published study by a University at Buffalo researcher. “Changes in social behavior during adolescence appear to be independent of pubertal hormones. They are not triggered by puberty, so we can’t blame the hormones,” says Matthew Paul, an assistant professor in UB’s Department of Psychology.

A first of its kind study shows typical interruptions experienced by on-call radiologists do not reduce diagnostic accuracy but do change what they look at and increase the amount of time spent on a case. The implication of the finding is that as radiologists contend with an increasing number of workplace interruptions, they must either process fewer cases or work longer hours — both of which have adverse effects in terms of patient outcomes, said Trafton Drew, the study's lead author. They also may spend more time looking at dictation screens than reviewing medical images.

Setting out to establish whether burning calories doing cardiovascular exercise was the same as burning calories doing resistance training, the study looked at physiological and hormonal responses to the two different workouts, when the number of calories burned and the duration of the two sessions was exactly the same. The study showed that resistance training triggers far greater fat-burning responses in the body than simple calorie counting suggests.

Proteins are finicky molecules. When removed from their native environments, they typically fall apart. To function properly, proteins must fold into a specific structure, often with the help of other proteins. Now a team of researchers at Northwestern University and the University of California at Berkeley have discovered a way to keep proteins active outside of a cell. The discovery could lead to a new class of materials with functions found only in living systems.
