Stickers and a smartphone for easy nitrite detection on foods

Nitrates and nitrites give processed meats their characteristic pink color and robust flavor. Although many consumers want to limit consumption of these preservatives because the substances can form potentially cancer-causing ...

Engineering team develops process to make implants safer

An interdisciplinary team of researchers at the University of Alabama at Birmingham have developed a new plasma-enabled process that could limit the proliferation of toxins from implants into a patient's bloodstream. The ...

A fast, efficient COVID-19 biosensor is under development

As the BA.5 omicron variant continues to spread, health experts are increasingly preparing for a future in which such COVID-19 variants emerge, surge and recede, similar to seasonal flu. An important part of staying on top ...

Scientists develop smart terahertz electro-optic modulator

A research group led by Prof. Sheng Zhigao from the Hefei Institutes of Physical Science (HFIPS) of the Chinese Academy of Sciences (CAS) developed an active and smart Terahertz (THz) electro-optic modulator. Their results ...

Laser writing may enable 'electronic nose' for multi-gas sensor

Environmental sensors are a step closer to simultaneously sniffing out multiple gases that could indicate disease or pollution, thanks to a Penn State collaboration. Huanyu "Larry" Cheng, assistant professor of engineering ...

New gel protects eggs—and maybe someday, heads—from damage

Humpty Dumpty, the famous egg of nursery rhyme fame, fell off a wall and couldn't be put back together again. But if he'd worn a protective jacket made of gelatin and cornstarch, he could have stayed intact. Researchers in ...
