Researchers take first-ever cryo-EM images of nitrogenase in action: Atomic-level-resolution images may provide new pathway to ammonia production
Previously, it has been impossible to capture the high-resolution images of nitrogenase, the only enzyme capable of reducing nitrogen into ammonia, during catalytic action. Now, for the first time, researchers at the University of California San Diego report near-atomic-resolution snapshots of nitrogenase during catalysis using cryogenic electron microscopy (cryoEM). The results were published in the […]
How To Ease Some Of The Vicarious Trauma You May Be Feeling Right Now
Thanks to social media, news reports and violent images that bombard us at all hours, we often experience what experts call vicarious trauma when a horrific event occurs ― like the Russian invasion of Ukraine, which as of Thursday morning had reportedly resulted in at least 40 deaths. It’s in our physiological nature as human […]
Sidewinding young stellar jets spied by Gemini South: Crystal-clear images of meandering bipolar stellar jets from young stars captured with adaptive optics
Sinuous stellar jets meander lazily across a field of stars in new images captured from Chile by the international Gemini Observatory, a Program of NSF’s NOIRLab. The gently curving stellar jets are the outflow from young stars, and astronomers suspect their sidewinding appearances are caused by the gravitational attraction of companion stars. These crystal-clear observations […]

Researchers find health benefits of Connecticut-grown sugar kelp: A first-of-its-kind study finds nutrition benefits for locally-grown sugar kelp, an increasingly important crop for the state
When most Americans think of seaweed, they probably conjure images of a slimy plant they encounter at the beach. But seaweed can be a nutritious food too. A pair of UConn researchers recently discovered Connecticut-grown sugar kelp may help prevent weight gain and the onset of conditions associated with obesity. In a paper published in […]
