Andrew Greytak, a chemist in the College of Arts and Sciences at the University of South Carolina, is leading a research team that's making the process of synthesizing quantum dots much more systematic. His group just published a paper in Chemistry of Materials detailing an effective new method for purifying CdSe nanocrystals...

Today, the Consortium for Advanced Simulation of Light Water Reactors (CASL) announced that its scientists have successfully completed the first full-scale simulation of an operating nuclear reactor. CASL is modeling nuclear reactors on supercomputers to help researchers better understand reactor performance with much higher...

Researchers found that most respondents considered cyberbullying to be more prevalent at the secondary school level. But respondents said harassment via social media, text message or university technology infrastructures intended for educational purposes and other platforms for online learning can be pernicious in the college...

Thresher sharks hunt schooling sardines in the waters off a small coral island in the Philippines by rapidly slapping their tails hard enough to stun or kill several of the smaller fish at once, according to research published July 10 in the open-access journal PLOS ONE by Simon Oliver of the...

On July 9, 2013, at 11:09 a.m. EDT, the sun erupted with an Earth-directed coronal mass ejection or CME, a solar phenomenon that can send billions of tons of particles into space that can reach Earth one to three days later. These particles cannot travel through the atmosphere to harm humans on...

The population of the critically endangered large primate known as the drill has been largely reduced to a few critical habitat areas in Cameroon, according to a recently published study by researchers with the San Diego Zoo's Institute for Conservation Research. The study highlights the challenges...

Matthew Wheeler, a University of Illinois professor of animal sciences and member of the Regenerative Biology and Tissue Engineering research theme at the Institute for Genomic Biology, worked with a team of five researchers to test 3-D-printed, bioresorbable airway splints in porcine models with...

Despite renewed global efforts for eradication, malaria continues to exert devastating effects on human health. An estimated 220 million people are infected each year by malaria-causing Plasmodium parasites, which are transmitted by the bite of an infected mosquito. This enormous infection burden...

Wildfires produce a witch's brew of carbon-containing particles, as anyone downwind of a forest fire can attest. But measurements taken during the 2011 Las Conchas fire near Los Alamos National Laboratory show that the actual carbon-containing particles emitted by fires are very different than...

Chemists have explained the structure of a non-classical carbocation. They have captured the 2-norbornyl cation as a crystal and determining beyond doubt the structure of this unusual and instable carbon compound. The 2-norbornyl cation is a non-classical carbocation, a molecule with a positively...
