Insight on how to build a better flu vaccine Posted: 31 Aug 2020 08:23 AM PDT Repeated exposure to influenza viruses may undermine the effectiveness of the annual flu vaccine. A team of researchers has developed an approach to assess whether a vaccine activates the kind of immune cells needed for long-lasting immunity against new influenza strains. The findings could aid efforts to design an improved flu vaccine.

Researchers discover a specific brain circuit damaged by social isolation during childhood Posted: 31 Aug 2020 08:23 AM PDT Researchers have identified specific sub-populations of brain cells in the prefrontal cortex, a key part of the brain that regulates social behavior, that are required for normal sociability in adulthood and are profoundly vulnerable to juvenile social isolation in mice.

Early rhythm control therapy improves outcomes in patients with atrial fibrillation Posted: 31 Aug 2020 08:23 AM PDT Patients with newly diagnosed atrial fibrillation benefit from early rhythm control therapy, according to new results.

Microgel immuno-acceptance method could improve pancreatic islet transplant success Posted: 31 Aug 2020 08:23 AM PDT Researchers have developed a new microgel drug delivery method that could extend the effectiveness of pancreatic islet transplantations -- from several years to possibly the entire lifespan of a recipient.

Research shows how a diet change might help US veterans with Gulf War illness Posted: 31 Aug 2020 08:23 AM PDT A new study shows the results from a dietary intervention in U.S. veterans suffering from Gulf War Illness, a neurological disorder in veterans who served in the Persian Gulf War from 1990 to 1991.

Wearable device could help EMTs, surgeons assess hemorrhage blood loss Posted: 31 Aug 2020 08:23 AM PDT Emergency medical technicians (EMTs), military medics, and emergency room physicians could one day be better able to treat victims of vehicular accidents, gunshot wounds, and battlefield injuries thanks to a new device under development that may more accurately assess the effects of blood loss due to hemorrhage.

Insect shows promise as a good, sustainable food source Posted: 31 Aug 2020 08:23 AM PDT With global food on the rise, a new study has found new evidence that the yellow mealworm shows promise as alternative source of nutritional protein.

Is being generous the next beauty trend? Posted: 31 Aug 2020 08:23 AM PDT New research found that more attractive people are more likely to be givers, and givers are rated as more attractive.

For people with high blood pressure, telemonitoring may cut heart attack, stroke rate by 50% Posted: 31 Aug 2020 08:22 AM PDT Adults with uncontrolled high blood pressure were about half as likely to have serious cardiovascular events in the five years after a pharmacist-led telemonitoring program compared to those receiving routine primary care. By reducing cardiovascular events, the telemonitoring intervention saved about $1,900 over five years in overall health care costs for each individual.

People with increased risk of Alzheimer's have deficits in navigating Posted: 31 Aug 2020 06:47 AM PDT Alzheimer's patients develop severe symptoms of spatial disorientation as the disease progresses and are unable to find even the simplest ways.

Reprogramming cardiac fibroblast cells to transform into beating heart muscle Posted: 31 Aug 2020 06:47 AM PDT Researchers have clarified the roles of matrix stiffness and mechanotransduction as well as the signaling pathways in the transformation of cardiac fibroblasts into contractile cardiomyocytes and show that soft substrates comparable to native myocardium improve the efficiency of this cardiac reprogramming.
