A new approach to producing ammonia using renewable electricity has overcome a fundamental energy limitation of the technology, opening new possibilities for cleaner and potentially more cost-effective production of one of the world’s most important chemicals.

LMU researchers challenge a decades-old model: genetically modified embryos lacking interferon tau can establish pregnancies and develop into healthy calves.

Public health and law enforcement agencies face a growing challenge in combating the fentanyl epidemic: They lack detailed and timely information on the harmful and potentially deadly substances that drug suppliers increasingly mix into the illicit fentanyl supply. 

Now, a new study from the National Institute of Standards and Technology (NIST) reveals how the prevalence of these adulterants changes over time and across different regions of the country.  Alerting first responders to the prevalence of specific adulterants in local supplies of fentanyl may make the difference between life and death.

“Our goal is that if some new additive pops up, say in Philadelphia, we’ll be able to tell public health officials when that additive is likely to show up in Delaware, Maryland or the West Coast,” said NIST chemist Ed Sisco.
