New research from Neurologist Dr. David Spence of The University of Western Ontario has shown that using 3-D ultrasound to identify ulcers in the carotid arteries is an effective way to pinpoint the small number of high-risk patients with asymptomatic carotid stenosis (ACS) who would benefit from surgery to prevent stroke. ACS is a blocking or narrowing of the carotid artery in the neck from which there have been no symptoms such as transient ischemic attacks (TIAs). The research is published...

Rice University researchers recently proved how a box of girl scout cookies could be worth $15 billion. The researchers invited a troop of Houston Girl Scouts over to the lab to show how scientists can make graphene out of just about anything with carbon. The scientists described in the journal ACS Nano how graphene can be made from just about any carbon source, including food, insects and waste. The venture started when Rice University chemist James Tour was dared during a meeting at his...
