Yeast already helps make bread and beer and cranks out the biofuel ethanol, but scientists believe it can be used to create an even more efficient fuel called isobutanol. Normally, yeast only creates a tiny amount of isobutanol. Now researchers at Princeton University have discovered a genetic switch that significantly ramps up production.

In a series of lab tests, a relatively common soil bacterium has demonstrated its ability to break down the difficult-to-remove class of pollutants called PFAS, researchers at Princeton University said.

The bacterium, Acidimicrobium bacterium A6, removed 60% of PFAS —…

In a major step toward developing portable scanners that can rapidly measure molecules on the pharmaceutical production line or classify tissue in patients’ skin, a Princeton-led team of researchers has created an imaging system that uses lasers small and efficient enough to fit on a microchip.

Fewer fish may reach breeding age as climate change skews timing of reproduction, food availability
July 24, 2019
Author
Written by Joseph Albanese for the Princeton Environmental Institute

Climate change may be depriving juvenile fish of their most crucial early food source by throwing off the synchronization of when microscopic plants known as phytoplankton bloom and when fish hatch, according to Princeton University researchers. The long-term effect on fish reproductivity could mean fewer fish available for human consumption. 

New research raises possibility of better anti-obesity drugs

Written by Princeton University

Effective weight-loss strategies call for eating less food, burning more calories — or ideally, both. But for the more than 90 million Americans who suffer from obesity, a disease that contributes to conditions ranging from heart disease to cancer, behavioral change is hard to accomplish or not effective enough, which is why scientists have…

Written by Jen A. Miller for the Office of Engineering Communications

As anyone who has purchased jewelry can attest, platinum is expensive. That's tough for consumers but also a serious hurdle for a promising source of electricity for vehicles: the hydrogen fuel cell, which relies on platinum.

Now a research team led by Bruce Koel, a…
