High-frequency antennas transmit radio waves across vast distances and even over mountain ranges using very little energy, making them ideal for military communications. These devices, however, have one big problem: They need to be huge to operate efficiently.
Instead of adding more bulk, University of Wisconsin–Madison engineers are working to increase the effective size of antennas by turning the military vehicles that carry them into transmitters — using the structures that support the antennas themselves to help broadcast signals.

On Monday, Britain's Human Fertilisation and Embryology Authority greenlighted experiments that will attempt to edit the genes of human embryos. The work, which will be the world's first officially approved use of public funding for human-genome editing, is to be led by The Francis Crick Institute's Kathy Niakan.
The news comes less than a year after the first reports of human-gene editing — published by Chinese scientists in the journal Protein and Cell — using the fantastic and at times troubling technology known as CRISPR. By harnessing an ancient defense mechanism built into bacteria, CRISPR allows scientists to target, delete and replace specific genes. It has been used extensively in other organisms, but research in humans has been slow.
MADISON, Wis. -- Inspired by mammals' eyes, University of Wisconsin-Madison electrical engineers have created the fastest, most responsive flexible silicon phototransistor ever made.
The innovative phototransistor could improve the performance of myriad products -- ranging from digital cameras, night-vision goggles and smoke detectors to surveillance systems and satellites -- that rely on electronic light sensors. Integrated into a digital camera lens, for example, it could reduce bulkiness and boost both the acquisition speed and quality of video or still photos.
Developed by UW-Madison collaborators Zhenqiang "Jack" Ma, professor of electrical and computer engineering, and research scientist Jung-Hun Seo, the high-performance phototransistor far and away exceeds all previous flexible phototransistor parameters, including sensitivity and response time.
The researchers published details of their advance this week in the journal Advanced Optical Materials.

The Manufacturing Advantage Conference provides a forum for manufacturers from across the region to learn best practices and participate in practical learning through interactive, hands-on breakout sessions, industry-expert keynote speakers and ample networking opportunities. We strive to carry on a solid tradition of providing impactful experiences to help manufacturers succeed in the areas of strategic direction, top-line growth, process improvement and people and culture.
Marquette University President Michael Lovell says he wants to double research at Marquette over the next five years.
Speaking at Thursday’s WIN-Milwaukee meeting, Lovell highlighted investments the university has made in facilities and programs that foster innovation, including the purchase of 12.5 acres in downtown Milwaukee that will house an athletic research facility. Developed in partnership with the Milwaukee Bucks and an unnamed health care provider, Lovell said the facility will provide a global draw to the university.
