Research shows that vegetarians appear to have a healthier biomarker profile than meat-eaters. 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.

MRSA skin infections are often treated with intravenous injection of antibiotics, which can cause significant side effects and promote the development of resistant bacterial strains. To solve these problems, researchers are developing a microneedle patch that delivers antibiotics directly into the affected skin area. New results that the microneedle patch effectively reduces MRSA bacteria in the skin.

A potential new vaccine developed by members of the Duke Human Vaccine Institute has proven effective in protecting monkeys and mice from a variety of coronavirus infections -- including SARS-CoV-2 as well as the original SARS-CoV-1 and related bat coronaviruses that could potentially cause the next pandemic.

By engineering a short chunk of protein, or peptide, that can prevent the attachment of human parainfluenza viruses to cells, researchers have improved a method in rodent models intended to help keep children healthy. The researchers built upon years of work on peptide treatments to generate one capable of blocking the HPIV3 attachment process.

An investigational gene therapy can safely restore the immune systems of infants and children who have a rare, life-threatening inherited immunodeficiency disorder, according to research. The researchers found that 48 of 50 children who received the gene therapy retained their replenished immune system function two to three years later and did not require additional treatments for their condition, known as severe combined immunodeficiency due to adenosine deaminase deficiency, or ADA-SCID.

Researchers report that they have built what they say is the world's smallest single-chip system, consuming a total volume of less than 0.1 mm^3. The system is as small as a dust mite and visible only under a microscope. In order to achieve this, the team used ultrasound to both power and communicate with the device wirelessly.

A new, patented method called Progressive Mechanoporation makes it possible to mechanically disrupt the membranes of cells for a short time period and let drugs or genes inside cells. In this way, researchers can test new therapies more easily than before.

Scientists have for the first time revealed the structure surrounding important receptors in the brain’s hippocampus, the seat of memory and learning. The new study focuses on the organization and function of glutamate receptors, a type of neurotransmitter receptor involved in sensing signals between nerve cells in the hippocampus region of the brain. The study reveals the molecular structure of three major complexes of glutamate receptors in the hippocampus.

A new study with zebrafish shows that a deadly form of skin cancer — melanoma — alters the metabolism of healthy tissues elsewhere in the body. The research suggests that these other tissues could potentially be targeted to help treat cancer. The scientists fed the zebrafish special versions of nutrients tagged with isotope labels. These labels allowed the scientists to track where nutrients go and into what molecules they get broken down. They found that a molecule being spit out by the tumor was being taken up by the liver to make glucose.

Eating a diet rich in fruit and vegetables is associated with less stress, according to new research. The study examined the link between fruit and vegetable intake and stress levels of more than 8,600 Australians aged between 25 and 91 participating in the Australian Diabetes, Obesity and Lifestyle (AusDiab) Study from Baker Heart and Diabetes Institute.
