UNIVERSITY OF PENNSYLVANIA SCHOOL OF MEDICINE PHILADELPHIA– Alcohol-impaired driving kills 29 people a day and costs $121 billion a year in the U.S. After years of progress in reducing alcohol-impaired driving fatalities, efforts began to stall in 2009, and fatalities started increasing again in 2015. With several studies demonstrating that drinkers cannot accurately estimate their...

Vegetarians have healthier levels of disease markers than meat-eaters
by European Association for the Study of Obesity Credit: CC0 Public Domain Vegetarians appear to have a healthier biomarker profile than meat-eaters, and this applies to adults of any age and weight, and is also unaffected by smoking and alcohol consumption, according to a new study in over 166,000 UK adults, being presented at this...

Scientists propose a rethink of the role of carbs in obesity
New research questions a well-established explanatory model of obesity. Maskot/Getty Images A popular theory asserts that carbohydrates in food cause a spike in insulin, which promotes fat storage and increases appetite, leading to overeating. However, recent research suggests that this “carbohydrate-insulin model” may be an oversimplification. In an article in the journal Science, researchers argue that while low carb, high fat diets...

Implantable ‘living pharmacy’ could control the circadian clock of war fighters and first responders to help them recover from disrupted sleep in half time
By STACY LIBERATORE FOR DAILYMAIL.COM PUBLISHED: 13:00 EDT, 14 May 2021 | UPDATED: 13:54 EDT, 14 May 2021 A new implantable ‘living pharmacy’ could help military personnel and first responders recover faster from disrupted sleep. Scientists at Northwestern University are developing a device to control the body’s circadian clock. The implant will include engineered cells that produce the same peptides...

Treatment for Alzheimer’s disease found effective in preventing inflammation in orthopedic implants
Dental and orthopedic implants are widely used around the world. Common causes for implant failure are the immune response against oral bacteria and titanium particles shed by the implant. These and other phenomena can generate an inflammatory response, activating the osteoclasts (bone resorbing cells), and ultimately leading to osteolysis (destruction of bone tissue) around the...

The Application and Future Potential of mRNA Vaccines
Vaccines are often described as one of the greatest public health interventions in recent history, based on the profound effect that they have had in decreasing global morbidity and mortality. Immunizations currently prevent 2-3 million deaths each year, and aside from sanitation and clean drinking water, they are credited as having the largest impact on population growth...

ITMO Researchers’ Light-Controlled Nanoparticles Will Play Key Role in Biosensor Development
Scientists from ITMO University have developed a production method for biointegrable nanoparticles that can be controlled via heat. With light irradiation, these particles change not only their shape, but their color, too. This discovery will be beneficial to the development of non-invasive biosensors, signal systems, and non-toxic dyes. The results of the study were published in the...

Researchers observe new complexity of traveling brain waves in memory circuits
UNIVERSITY OF CALIFORNIA – SAN FRANCISCO Researchers at UC San Francisco have observed a new feature of neural activity in the hippocampus – the brain’s memory hub – that may explain how this vital brain region combines a diverse range of inputs into a multi-layered memories that can later be recalled. Using a special “micro-grid” recording...
