Broken bones have a unique capacity to heal. The new bone that forms along the fracture line, called callus, starts out as a soft tissue and, over time, it hardens into bone that is just as strong—or stronger—than before the break.
But in some cases, the healing process goes awry. This failure to heal is called a nonunion, a painful and often debilitating condition that requires further medical intervention.
Former NASA astronaut and mechanical engineering and mechanics professor Terry Hart ’68 ’88H will deliver the address at Lehigh’s 152nd spring commencement on Monday, May 18.
Hart was a member of NASA’s “Group 8”—the first selection of space shuttle astronaut candidates in nine years—and later joined NASA’s 11th space shuttle mission aboard the STS 41-C Challenger, launched from Kennedy Space Center on April 6, 1984.
As a property owner, you may have more agency over the extent of flooding after a storm than you may think.
A team including Lehigh’s Industrial and Systems Engineering Professor Frank E. Curtis was awarded second place in the highly competitive Grid Optimization (GO) Competition, run and sponsored by the U.S.
If you’re able to walk without pain, give a silent shout-out to your cartilage.
Every time you take a step, this flexible tissue absorbs the load and transfers it to the bone, allowing you to move freely. But unlike bone, if cartilage gets damaged—by injury, wear and tear, or inflammation—it can’t regenerate. Over time, the damaged tissue degrades, and walking becomes progressively more painful as the bones come in contact with each other.
Civil engineering professor Dan M. Frangopol, the Fazlur R. Khan Endowed Chair of Structural Engineering and Architecture, has received the following recognitions:
The building blocks of artificial intelligence—computing power, data, and mathematical models—have been around for decades. But only recently have they been employed at a level of sophistication and on a large enough scale to weave machine learning into our everyday lives.
Natasha Vermaak, an associate professor of mechanical engineering and mechanics, is the founding chair of a new Technical Committee for the Design of Engineering Materials (DEM TC) within the American Society of Mechanical Engineers (ASME).
Anand Jagota, professor and founding chair of Lehigh University’s bioengineering department, has arrived at a milestone in his 15 years of researching friction and adhesion—one that could lead to innovations in tires, robotics, and biomaterials down the road.
