Mars Perseverance rover data suggests presence of past microbial life

Researchers uncover potential biosignatures on Mars

A new study co-authored by Texas A&M University geologist Dr. Michael Tice has revealed potential chemical signatures of ancient Martian microbial life in rocks examined by NASA’s Perseverance rover.

The findings, published by a large international team of scientists, focus on a region of Jezero Crater known as the Bright Angel formation—a name chosen from locations in Grand Canyon National Park because of the light-colored Martian rocks...

Electronic devices lose energy as heat due to the movement of electrons. Now, a breakthrough in nanoengineering has produced a new kind of switch that matches the performance of the best traditional designs while pushing beyond the power-consumption limits of modern electronics.

Researchers from the University of Michigan have achieved what scientists have been trying to execute for a long time: designing electronics that harness excitons—pairs of an electron and a corresponding hole (a missing electron) bound together forming a charge-neutral particle—instead of electrons.

The newly designed nanoengineer...

Mysterious ‘red dots’ in early universe may be ‘black hole star’ atmospheres

Mysterious 'red dots' in early universe may be 'black hole star' atmospheres
Artist’s impression of a black hole star (not to scale). Mysterious tiny pinpoints of light discovered at the dawn of the universe may be giant spheres of hot gas that are so dense they look like the atmospheres of typical nuclear fusion-powered stars; however, instead of fusion, they are powered by supermassive black holes in their center that rapidly pull in matter, converting it into energy and giving off light.

Tiny red objects spotted by NASA’s James Webb Space Telescope (JWST) are offering scientists new insights into the origins of galaxies in the universe—and may represent an entirely new class of celestial object: a black hole swallowing massive amounts of matter and spitting out light.

Using the first dat...

A ‘universal’ therapy against the seasonal flu? Antibody cocktail targets virus weak spot

Artist’s representation of non-neutralizing antibodies targeting the flu virus.

An unusual therapy developed at The Jackson Laboratory (JAX) could change the way the world fights influenza, one of the deadliest infectious diseases. In a new study in Science Advances, researchers report that a cocktail of antibodies protected mice—including those with weakened immune systems—from nearly every strain of influenza tested, including avian and swine variants that pose pandemic threats.

Unlike current FDA-approved flu treatments, which target viral enzymes and can quickly become useless as the virus mutates, this therapy did not allow viral escape, even after a month of repeated exposure in animals...
