The U.S. opioid epidemic is being driven by an unprecedented surge in deaths from fentanyl and other synthetic opiates. Fentanyl’s powerful effects are long-lasting, and even tiny amounts of the drug can lead to an overdose. Antidotes, such as naloxone, do not last long enough in the body to fully counter the drug, requiring repeated injections. Now, scientists report that they are developing single-dose, longer-lasting opioid antidotes using polymer nanoparticles.

The researchers will present their results today at the American Chemical Society (ACS) Spring 2019 National Meeting & Exposition.

This star-studded image shows us a portion of Messier 11, an open star cluster in the southern constellation of Scutum (the Shield). Messier 11 is also known as the Wild Duck Cluster, as its brightest stars form a “V” shape that somewhat resembles a flock of ducks in flight.

Messier 11 is one of the richest and most compact open clusters currently known. By investigating the brightest, hottest main sequence stars in the cluster, astronomers estimate that it formed roughly 220 million years ago...

New research explores graphene-silicon devices for photonics applications. If you use a smartphone, laptop, or tablet, then you benefit from research in photonics, the study of light. At the University of Delaware, a team led by Tingyi Gu, an assistant professor of electrical and computer engineering, is developing cutting-edge technology for photonics devices that could enable faster communications between devices and thus, the people who use them.

The research group recently engineered a silicon-graphene device that can transmit radiofrequency waves in less than a picoseco...

Scientists create membraneless organelle to build proteins in living cell. For the first time, scientists have engineered the complex biological process of translation into a designer organelle in a living mammalian cell...
