Personalized biohybrid microswimmers for therapeutic cargo delivery

Tiny biohybrid robots on the micrometer scale can swim through the body and deliver drugs to tumors or provide other cargo-carrying functions. The natural environmental sensing tendencies of bacteria mean they can navigate toward certain chemicals or be remotely controlled using magnetic or sound signals.

A genetic toolkit to produce multifunctional magnetic nanoparticles

Magnetic bacteria might soon be used for the production of novel biomaterials. A team of microbiologists at the University of Bayreuth led by Prof. Dr. Dirk Schüler developed a modular system for the genetic reprogramming of bacteria, thereby turning the organisms into cell factories for multifunctional magnetic nanoparticles that combine various useful functions and properties.

Extreme endurance exercise can increase risk of cardiovascular events

For most people, the benefits of aerobic exercise far outweigh the risks, however, extreme endurance exercise - such as participation in marathons and triathlons for people who aren't accustomed to high-intensity exercise - can raise the risk of sudden cardiac arrest, atrial fibrillation (a heart rhythm disorder) or heart attacks, according to a new Scientific Statement "Exercise-Related Acute Cardiovascular Events and Potential Deleterious Adaptations Following Long-Term Exercise Training: Placing the Risks Into Perspective-An Update from the American Heart Association," published today in the Association's premier journal Circulation.

Study finds wide state-by-state variation in melanoma rates caused by ultraviolet radiation

A new study finds a wide state-by-state variation in rates of melanoma caused by ultraviolet (UV) exposure with highest rates in several states on the East and West Coast including Hawaii, but also a few landlocked states, including Utah, Vermont, and Minnesota.

Study provides evidence of aerosol exposure to microcystins among coastal residents

Florida has experienced numerous harmful algal blooms in recent years, including blue-green algae and their toxins in 2016 and 2018. Despite their intensity and frequency, there is scant data on human exposure to these blooms and concentrations of the toxins they produce in tissues of exposed individuals.
