Second California Nurse Dies by Suicide on the Job
A nurse took his own life at Kaiser Permanente Santa Clara Medical Center last week, marking the second apparent suicide by a nurse in a matter of months. On April 30, the nurse shot himself in the supply closet halfway through his shift in the emergency department, according to NBC Bay Area. His name has […]
Revising the lifecycle of an important human parasite
“We have been interested in the romantic life of the parasite Cryptosporidium for some time,” says Boris Striepen, a scientist in Penn’s School of Veterinary Medicine. Cryptosporodium is a leading cause of diarrheal disease in young children around the world. The intestinal parasite contributes to childhood mortality and causes malnutrition and stunting. How a parasite […]
Changes in vegetation shaped global temperatures over last 10,000 years
Follow the pollen. Records from past plant life tell the real story of global temperatures, according to research from a climate scientist at Washington University in St. Louis. Warmer temperatures brought plants — and then came even warmer temperatures, according to new model simulations published April 15 in Science Advances. Alexander Thompson, a postdoctoral research […]
Longevity Without Alzheimer’s Tied to Lifestyle
A healthy lifestyle was tied to a longer life but the extra years did not mean more time living with Alzheimer’s dementia, a prospective study showed. People who had four or five healthy lifestyle factors — spanning diet, cognitive activity, physical exercise, smoking, and alcohol patterns — at age 65 lived longer than their counterparts […]
New study reveals why HIV remains in human tissue even after antiretroviral therapy: Discovery could open the door to new treatments that improve our immune system’s ability to eliminate the stubborn virus, lead to strides in MS research.
Thanks to antiretroviral therapy, HIV infection is no longer the life sentence it once was. But despite the effectiveness of drugs to manage and treat the virus, it can never be fully eliminated from the human body, lingering in some cells deep in different human tissues where it goes unnoticed by the immune system. Now, […]
Opinion | Coping With Rejection Requires Resilience
My first serious rejection in life came in the form of a letter — a rejection letter from medical school. All 10 I’d applied to in fact. I wasn’t expecting to be shut out from my chosen profession. So, I regrouped, and I was accepted into medical school the second time around. I guess you […]
Changing your diet could add up to a decade to life expectancy, study finds: A new model, available as an online calculator, estimates the impact of dietary changes on life expectancy
A young adult in the U.S. could add more than a decade to their life expectancy by changing their diet from a typical Western diet to an optimized diet that includes more legumes, whole grains and nuts, and less red and processed meat, according to a new study publishing Feb. 8 in PLOS Medicine by […]
Blood proteins could be the key to a long and healthy life, study finds
Two blood proteins have been shown by scientists to influence how long and healthy a life we live, research suggests. Developing drugs that target these proteins could be one way of slowing the ageing process, according to the largest genetic study of ageing. As we age, our bodies begin to decline after we reach adulthood, […]
Listening to the leaves: Adding bioinspired veins to foamed polymers
Many lessons learned in life are learned from trees. Stand firm. Good things take time. Bend, don’t break. But metaphors aside, our stately arboreal neighbors offer a wealth of scientific wisdom — and we have a lot to learn. Simply by existing, trees are nature’s first materials scientists. Like many plants, they have vascular systems, […]
Invasive species ‘hitchhiking’ on tourist and research ships threaten Antarctica’s unique ecosystems
Marine life hitching a ride on ocean-crossing ships poses a threat to Antarctica’s pristine ecosystems, with the potential for invasive species to arrive from almost anywhere across the globe, say the authors of a new study. New research by the University of Cambridge and the British Antarctic Survey has traced the global movements of all […]
