Frontiers of health: Following the map

Mona Singh doesn't use the maps in her office to get from point A to point B -- she uses them to find meaning hidden in biological data, which may help advance the understanding of disease at the genetic level.

Frontiers of health: New spin on heart valves

In a roundabout way, propellers advanced Julie Young's latest project—a new and improved heart valve replacement. "The blades of a propeller look very much like the leaflets in a mechanical heart valve," said Young, an assistant professor of civil and environmental engineering, who studied propellers for her Ph.D. dissertation at the University of Texas at Austin. "The same principles apply on a much smaller scale."

Smits returns as mechanical and aerospace chair

Alexander Smits will become chair of the Department of Mechanical and Aerospace Engineering as of July 1, returning to the position he held from 1998 to 2004.

Frontiers of health: Bugs for drugs

Bacteria have to work to earn their keep in the lab of David Wood, assistant professor of chemical engineering. Designed to respond to human hormones, the busy bugs may help identify new compounds to treat endocrine problems, including Graves' disease and estrogen-related disorders.

Frontiers of health: Sight for sore eyes

Szymon Suckewer needs eye surgery, but he's not going under the knife just yet -- he'd rather wait until no knife is necessary. Having recently developed an incision-free eye surgery technique, he's confident that will soon be an option.

For computers or humans, theory of learning inspires unusual mix of subjects

This year marks the 10th anniversary of a class that yokes two very unlikely subjects -- philosophy and engineering.

Felten and Internet experts ponder privacy issues

Ed Felten opened a Reunions 2007 panel discussion on Internet privacy by showing images from Google's new map service called "Street View."

The annual award is given for an original paper in the field of wireless communications published in the IEEE Transactions on Wireless Communications, selected based upon its originality, utility, timeliness and clarity of presentation.

Hypersonics expert whisks students to the leading edge of aeronautics

If asking students to design an airplane doesn't seem challenging enough, how about a supersonic jet? No, how about a "global hyperliner," a vehicle that could carry a person out of the atmosphere and nearly halfway around the world in three hours?
