Scientists engineer bacteria-killing molecules from wasp venom

A team led by scientists in the Perelman School of Medicine at the University of Pennsylvania has engineered powerful new antimicrobial molecules from toxic proteins found in wasp venom. The team hopes to develop the molecules ...

Blood breakdown product commandeers important enzyme

The hemoglobin in the red blood cells ensures that our body cells receive sufficient oxygen. When the blood pigment is broken down, heme is produced, which in turn can influence the protein cocktail in the blood. Researchers ...

COVID-19 antibody tests: How reliable are they?

With stay-at-home orders expiring around the world, many hope that COVID-19 antibody testing will help businesses and institutions reopen safely. Determining whether people have been infected with SARS-CoV-2 is a key tool ...

A leap in using silicon for battery anodes

The same material you'll find at the tip of a pencil—graphite—has long been a key component in today's lithium-ion batteries. As our reliance on these batteries increases, however, graphite-based electrodes are due for ...

'Decoy' nanoparticles can block HIV and prevent infection

Flipping the standard viral drug targeting approach on its head, engineers at the University of California San Diego have developed a promising new "nanosponge" method for preventing HIV from proliferating in the body: coating ...
