Romancing the Scutoid

As an embryo develops, tissues bend into complex three-dimensional shapes that lead to organs. Epithelial cells are the building blocks of this process, forming, for example, the outer layer of skin. They also line the blood vessels and organs of all animals.

These cells pack together tightly. To accommodate the curving that occurs during embryonic development, it has been assumed that epithelial cells adopt either columnar or bottle-like shapes.

However, a group of scientists dug deeper into this phenomenon and discovered a new geometric shape in the process.

Powering the Future: Wenxin Liu Awarded Grant from Office of Naval Research

Traditional, centralized power grids—where power is generated, transmitted and then distributed to users—is fast becoming a thing of the past. Such systems are inefficient and vulnerable to attack. In addition, renewable energy sources, such as wind and solar, have led to more compact generators. For all these reasons, the future of power is power electronics-based microgrids.

A microgrid is exactly what it sounds like: a small grid. It consists of multiple distributed generators and loads and can work in both grid-connected- or autonomous- modes.

Lehigh engineers among group awarded $2.5M federal transportation grant

Engineering faculty at Lehigh’s P.C. Rossin College of Engineering and Applied Science are included in a consortium that was recently awarded $2.5 million by the U.S. Department of Transportation (US DOT) in its first round of funding for Regional University Transportation Centers. The multi-year grant is authorized under the Fixing America’s Surface Transportation Act or the FAST Act, the first federal law in more than a decade to provide long-term funding certainty for surface transportation infrastructure planning and investment.

Triggering immune system to defeat deadly bacteria

If immunotherapy—the harnessing of the body’s immune system—can destroy cancer cells, as has been demonstrated, why not try to trigger the body’s immune system to battle deadly bacteria?

That question drives Marcos Pires’ pursuit of what he calls bacterial immunotherapy or immunobiotics—using the human immune system’s powerful mechanisms of preventing entry and colonization of pathogens to defeat the deadliest, antibiotic-resistant bacteria.
