Do family members belong in ICU during procedures? Study finds clinicians mixed on practice
Do family members of loved ones who are critically ill and being treated in an intensive care unit at a hospital belong there when clinicians are performing bedside procedures? A new study from Intermountain Healthcare researchers finds many critical care clinicians have conflicting feelings about the practice.

Just like toothpaste: Fluoride radically improves the stability of perovskite solar cells
Solar cells made of perovskite hold much promise for the future of solar energy. The material is cheap, easy to produce and almost as efficient as silicon, the material traditionally used in solar cells. However, perovskite degrades quickly, severely limiting its efficiency and stability over time. Researchers from Eindhoven University of Technology, energy research institute DIFFER, Peking University and University of Twente have discovered that adding a small amount of fluoride to the perovskite leaves a protective layer, increasing stability of the materials and the solar cells significantly. The solar cells retain 90 percent of their efficiency after 1000 hours operation at various extreme testing conditions. The findings are published today in the leading scientific journal Nature Energy.

Shedding light on cancer metabolism in real-time with bioluminescence
EPFL scientists have invented a new way to quantify—in real-time—glucose metabolism of cancerous tumors by making them bioluminesce. This new light probe is not radioactive and works on living organisms such as mice that carry the tumor cells. The technique requires tagged tumor cells, two jabs and a camera. The results are published in Nature Methods.

Studies: Benralizumab not effective reducing exacerbations in moderate to very severe COPD
More than 15.3 million people in the U.S. suffer from chronic obstructive pulmonary disease (COPD), which is the third leading cause of death in this country, according to the American Lung Association. Patients often experience potentially life-threatening exacerbations, which can include days-long flare-ups of symptoms including shortness of breath that occur when the airways narrow from muscle tightness, swelling and mucus.
