Because glucose is energy dense and abundant in the body, scientists have been trying to use it in fuel cells to power medical implants. Glucose fuel cells made so far store a large amount of energy but cannot deliver it in the quick bursts that an implant, such as a pacemaker or brain stimulator, needs. Now, researchers have made a compact device that delivers such bursts by combining a biofuel cell with a supercapacitor. Read More.
Prisons are about as devoid of nature as a place can get. The concrete and steel only adds to the misery and rage felt by those confined inside. Read More.
University of Utah ecologist Nalini Nadkarni is no fashion mogul. But she is a scientist actively engaged in public outreach, working to bring the wonder and curiosity of the natural world to people, even those who may have no interest in natural history museums, nature documentaries or natural history magazines.Read More.
The rapid spread of the Zika virus has researchers working to find vulnerabilities in the virus and develop a treatment. At the University of Utah, chemists Cynthia Burrows and Aaron Fleming used RNA structures called G-quadruplexes as genetic landmarks to compare Zika with other related viruses. In a new study, Burrows and Fleming describe how the pattern of G-quadruplexes in Zika’s genome suggests a possible drug target. Read More.
