Super-Heavy Element 117 Newest Addition to Periodic Chart
Discovery of a new super-heavy element sheds light on the basic organization of matter and strengthens the likelihood that still more massive elements may form an “island of stability”— a cluster of stable super-heavy elements that could form novel materials with exotic and as-yet-unimagined scientific and practical applications. Vanderbilt physicist Joe Hamilton… Read MoreAug 22, 2010

Nanosponge Drug Delivery Targets Cancerous Tumors
Eva Harth’s method for targeted drug delivery relies on relatively simple chemistry, making commercial production more viable. Imagine treating cancerous tumors by filling tiny sponges with drugs, attaching special chemical “linkers” that bond to the surface of tumor cells, and then injecting these sponges into the body. That’s the idea behind a nanosponge… Read MoreAug 22, 2010

Sexual Parasite Sheds Light on Disease Treatments
About 100 million years ago, the bacterium Wolbachia came up with a trick that has made it one of the most successful parasites in the animal kingdom: It evolved the ability to manipulate the sex lives of its hosts. “When it developed this capability, Wolbachia spread rapidly among the world’s… Read MoreApr 7, 2010

Sniper Location System Turns Heads
Imagine a platoon of soldiers carrying personal digital assistants that can display the location of enemy shooters in three dimensions and accurately identify the caliber and type of their weapons. Engineers at Vanderbilt University’s Institute for Software Integrated Systems (ISIS) have developed a system that can give soldiers just such… Read MoreAug 5, 2009

‘Hidden’ Echoes Play Role in Memory
Functional magnetic resonance imaging is revealing clues about visual memory. Vanderbilt researchers have discovered that early visual areas, long believed to play no role in higher cognitive functions such as memory, retain information previously hidden from brain studies. Researchers made the discovery using a new technique for decoding… Read MoreAug 5, 2009
