Even though as many as 50,000 people die of traumatic brain injuries in the United States every year, the equipment used to measure vital stats like intracranial pressure is usually made up of decades-old technology. To address this, researchers at the University of Illinois at Urbana-Champaign and the Washington University School of Medicine in St. Louis have created a new sensor that's far less invasive and much safer than the existing technology.
Fans of The Simpsons may recall Lisa using genetic engineering to create a super tomato that she hoped would cure world hunger. Now researchers at Washington University in St. Louis (WUSTL) have come close to the real thing, not through genetic engineering, but with the use of nanoparticles. Although the individual fruit aren't as large as Lisa's creation, the team's approach has resulted in tomato plants that produced almost 82 percent more fruit by weight, with the fruit also boasting higher antioxidant content.
