In the not-too-distant future, the search for signs of life on Mars and the moon could see the next generation of robots exploring a new frontier: subsurface lava tubes. These missions could also help us determine the best locations for establishing human bases.

To see whether this could be feasible, scientists tested three autonomous robots in a lava cave on the Spanish island of Lanzarote.

Lava tubes are deep underground caves formed by volcanic activity and are found in various parts of the world, as well as on Mars and the moon...

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...
