No Evidence That Depression is Caused by Low Serotonin Levels, Finds New Comprehensive Review

After decades of study, there remains no clear evidence that serotonin levels or serotonin activity are responsible for depression, according to a major review of prior research led by UCL scientists. The new umbrella review – an overview of existing meta-analyses and systematic reviews – published in Molecular Psychiatry, suggests that depression is not likely caused by a chemical imbalance, and calls into question what antidepressants do.

Tiny Swimming Microbots Treat Deadly Pneumonia in New Animal Study

Nanoengineers at the University of California San Diego have developed microscopic robots, called microrobots, that can swim around in the lungs, deliver medication and be used to clear up life-threatening cases of bacterial pneumonia. In mice, the microrobots safely eliminated pneumonia-causing bacteria in the lungs and resulted in 100% survival. By contrast, untreated mice all died within three days after infection. The microrobots are made of alga>> Read Post

Daily Multivitamin May Improve Cognition and Protect Against Cognitive Decline

Could taking a daily multivitamin help maintain cognitive health with aging and possibly prevent cognitive decline? According to new research from Wake Forest University School of Medicine, conducted in collaboration with Brigham and Women’s Hospital in Boston, taking a daily supplement may improve cognition in older adults, but additional studies are needed to confirm these findings before any health recommendations are made. The study also showed that da>> Read Post

Researchers Link Ultra-Processed Foods to Increased Risk of Heart Disease, Bowel Cancer and Death

Two large studies published by The BMJ reveal links between high consumption of ultra-processed foods and increased risks of cardiovascular disease, bowel (colorectal) cancer and death. The findings add further evidence in support of policies that limit ultra-processed foods and instead promote eating unprocessed or minimally-processed foods to improve public health worldwide. They also reinforce the opportunity to reformulate dietary guidelines >> Read Post

Taurine: Study Identifies Antioxidant, Anti-Aging and Disease Fighting Benefits of a Common Amino Acid

When our cells process the oxygen we breathe and the food we eat every day in order to survive, they generate potentially toxic by-products known as “free radicals.” Some of these molecules perform functions essential to the organism, but if there are too many of them the cells’ internal structures can be damaged, preventing the cells from functioning properly and potentially leading to chronic disease. This process is called oxidative stress. Our b>> Read Post

Study Links Higher Fish Consumption to Increased Risk of Melanoma

Eating higher amounts of fish, including tuna and non-fried fish, appears to be associated with a greater risk of malignant melanoma, according to a large study of U.S. adults published in the journal Cancer Causes and Control. “This study is important because it’s very large and it’s prospective by design, meaning that fish intake was assessed before the development of cancer,” said author Eunyoung Cho, an associate professor of dermatology and epi>> Read Post

New Bioengineered Cornea Restores Sight to the Blind and Visually Impaired

Researchers have developed a new bioengineered implant made of collagen protein from pig's skin, which resembles the human cornea. In a pilot study, the implant restored vision to 20 people with diseased corneas, most of whom were blind prior to receiving the implant. The promising results bring hope to those suffering from corneal blindness and low vision by providing an alternative to the transplantation of donated human corneas, which are scarce >> Read Post
