Biomedical engineers have developed a miniature self-sealing model system for studying bleeding and the clotting of wounds. The researchers envision the device as a drug discovery platform and potential diagnostic tool. A description of the system, and representative movies, are scheduled for publication in Nature Communications. Lead author Wilbur Lam, MD, PhD says that blood clotting involves the damaged blood vessel, platelets, ...

  Despite the potentially severe consequences of illness and even death, only about 40% of adults in the United States receive flu shots each year; however, researchers believe a new self-administered, painless vaccine skin patch containing microscopic needles could significantly increase the number of people who get vaccinated.

A team of neuroscientists from Emory University's Silvio O. Conte Center for Oxytocin and Social Cognition has discovered a key connection between areas of the adult female prairie vole's brain reward system that promotes the emergence of pair bonds. Results from this study, could help efforts to improve social abilities in human disorders with impaired social function, such as autism. In addition to the online posting, the study is expected to b...

Frog mucus is loaded with molecules that kill bacteria and viruses, and researchers are beginning to investigate it as a potential source for new anti-microbial drugs. One of these "host defense peptides," courtesy of a colourful tennis-ball-sized frog species (Hydrophylax bahuvistara) from southern India, can destroy many strains of human flu and protect mice against flu infection, researchers report in the journal Immunity.

The red berries of the Brazilian peppertree—a weedy, invasive species common in Florida—contain an extract with the power to disarm dangerous antibiotic-resistant staph bacteria, scientists at Emory University have discovered. The journal Scientific Reports is publishing the finding, made in the lab of Cassandra Quave, an assistant professor in Emory's Center for the Study of Human Health and in the School of Medicine's...
