Germ-fighting catheter coating may help prevent infections — ScienceDaily

Brown University researchers have developed a new antibacterial coating for intravascular catheters that could one day help to prevent catheter-related bloodstream infections, the most common type of hospital-acquired infection. “These kinds of infections are a major burden for hospitals, health care providers and most of all for patients,” said Anita Shukla, an assistant professor of…

Early onset menstruation linked to high blood pressure in late adulthood, UGA study finds — ScienceDaily

The age a woman begins menstruation is associated with having high blood pressure later in her life, according to a team of researchers at the University of Georgia. Specifically, researchers found that early onset menstruation significantly increased risk of hypertension in late adulthood, even after controlling for independent social economic factors, lifestyle behaviors, and other…

Frilly surfaces that help slugs move may motivate future energy-efficient, soft-body robots, according to researchers — ScienceDaily

What do pizza slices, sea slugs and one possible design for future soft-bodied robots have in common? They all have frilly surfaces, and new insights about the surprising geometry of frilly surfaces may help a future generation of energy-efficient and extremely flexible soft-body robots move. The complex folds of a frilly surface like coral reefs…

Innovation in physics is the foundation of modern technology and contributes to the US economy in several key ways — ScienceDaily

Industrial physics plays a significant role in driving the U.S. economy, according to a new report by the American Physical Society, which will be described this week at the 2019 APS March Meeting in Boston. The report, “The Impact of Industrial Physics on the U.S. Economy,” found that industrial physics contributed an estimated $2.3 trillion…

Tree seedlings grow less effectively in soil located below their ‘mother’ tree — ScienceDaily

It’s widely accepted within agriculture that maintaining genetic diversity is important. In areas where crop plants are more diverse, pathogens might kill some plants but are less likely to wipe out an entire crop. Few studies, however, have focused on such highly specialized pathogens in natural plant communities. In diverse plant communities, pathogens are thought…
