He was passionate about his students—yet known as a severe taskmaster. He had a unique teaching style, but had no qualms about flunking students who didn’t pass muster. He was a prolific author. He was unwaveringly ethical. He did not suffer fools. He thought highly of UW-Madison. And he had an excellent relationship with chipmunks—all [...]

Cold enough to see clearly

Astrophysics instruments that measure very faint, distant sources of light need to be very cold to be sensitive enough to detect individual photons. These detectors work by measuring the change in temperature that occurs when a single photon hits the detector and deposits energy. Because this temperature rise is extremely tiny, only a very cold [...]

Aluminum and magnesium alloys hold great potential for manufacturers, as these alloys are much lighter than traditional high-strength materials such as iron and steel. However, most high-strength aluminum and magnesium alloys are difficult to cast because these materials tend to crack as they solidify in casting molds. This “hot tearing” is a major barrier to [...]

Atrial fibrillation is a condition where the upper chambers of a patient’s heart beat irregularly, which can cause blood to pool and increase the risk of stroke-causing clots. Treatment is difficult: A physician has to maneuver a catheter around a patient’s chest cavity to the diseased regions of the heart, which are then frozen or [...]

During a long bike ride, it’s not unusual for cyclists to experience hand or finger numbness, a very common condition known as cyclist’s palsy. The condition ranges from mild tingling to, sometimes, long-term nerve damage and hand muscle atrophy over time. A team of UW-Madison engineers has scientifically measured hand pressure during cycling and studied [...]

Behind every rubber product is a story that begins deep in the Amazon near a small city called Leticia at the southernmost tip of Colombia. In the early 20th century, 90 percent of the world’s rubber came from this region, at the cost of millions of indigenous peoples’ lives and significant rainforest destruction. Though Leticia [...]

Few university vehicle teams can attribute their success to hamburgers— lots and lots of hamburgers. Yet that’s exactly what future members of the University of Wisconsin-Madison vehicle teams will be able to do. At the 2009 Society of Automotive Engineers (SAE) Baja Wisconsin competition, in Burlington, Wisconsin, team members raised $10,000 by running a food [...]

One method for treating cancer involves injecting a patient with a metal probe in close proximity of a tumor. The probe is then rapidlycooled to the point of freezing and killing the surrounding tissue. Called a cryoprobe, the technique is gaining traction in medicine, but the procedure isn’t as simple or fast as many doctors [...]
