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

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...

New technology turns paintings into holograms, bringing art to life

New technology turns paintings into holograms, bringing art to life

Artists are always looking for new ways to create and express themselves. A growing trend is the use of multiple layers of see-through materials, such as Plexiglas, to create paintings that have real depth, transforming two-dimensional images into three-dimensional illusions that feel more realistic and lifelike. But can these layered works be made even more immersive?

A new study, published in Royal Society Open Science, answers this question by demonstrating a novel process to transform a multilayer acrylic painting into a fullcolor, three-dimensional hologram. In addition to offering a striking way to experience art, this technique provides a novel method for preserving and reproducing valuable works.

The researchers used a painting of a tiger titled “Taxonomy Test 1” by reno...
