Neurons in the gut produce a molecule that plays a pivotal role in shaping the gut’s immune response during and after inflammation, according to a new study by Weill Cornell Medicine investigators. The findings suggest that targeting these neurons and the molecules they produce could open the door to new treatments for inflammatory bowel disease and other disorders driven by gut inflammation.

Hundreds of millions of neurons make up the enteric nervous system, the “second brain” of the body, where they orchestrate essential functions of the gut such as moving food through the intestines, nutrient absorption and blood flo...

A team of scientists from Korea and Japan has discovered a new type of crystal that can “breathe”—releasing and absorbing oxygen repeatedly at relatively low temperatures. This unique ability could transform the way we develop clean energy technologies, including fuel cells, energy-saving windows, and smart thermal devices.

The newly developed material is a special kind of metal oxide made of strontium, iron, and cobalt...

Astronomers discover new type of supernova triggered by black hole-star interaction

A study led by the Center for Astrophysics | Harvard & Smithsonian (CfA) has captured the explosive interaction between a black hole and a nearby massive star (blue), as depicted in this artist’s conception. As the separation between the star and the black hole decreased, the black hole’s intense gravity pulled gas and dust off of the star into a disk. Before the star was able to swallow the black hole, gravitational stress from the black hole triggered the star’s explosion. Collisions between the stellar explosion and shells of material from earlier interactions located above and below the disk powered a dramatic re-brightening event...

Tiny chip could unlock gamma ray lasers, cure cancer, and explore the multiverse

CU Denver Develops Quantum Tool that May Lead to Gamma-Ray Lasers and Access the Multiverse  
Graduate student Kalyan Tirumalasetty (left) and Assistant Professor of Electrical Engineering Aakash Sahai work on their quantum technology in a lab.

Imagine a safe gamma ray laser that could eradicate cancer cells without damaging healthy tissue. A University of Colorado Denver engineer is on the cusp of giving scientists a new tool that can help them turn sci-fi into reality.

Imagine a safe gamma ray laser that could eradicate cancer cells without damaging healthy tissue. Or a tool that could help determine if Stephen Hawking’s multiverse theory is real by revealing the fabric underlying the universe.

Assistant Professor of Electrical Engineering Aakash Sahai, PhD, has developed a quantum breakthrough that could help those sci-fi ideas develop and has sent a ripple of exciteme...
