Nearby super-Earth may be our best chance yet to find alien life

A nearby super-Earth may be one of the best chances yet to search for life beyond our solar system. A newly detected super-Earth just 20 light-years away is giving scientists one of the most promising chances yet to search for life beyond our solar system. The discovery of the exoplanet orbiting in the habitable zone of its star was made possible by advanced spectrographs designed at Penn State and by decades of observations from telescopes around the world.

A possible “supe...

Turning the gut microbiome into a longevity factory

New research finds that low doses of the antibiotic cephalordine induces the cps operon in bacteria, visualized in red. This operon is responsible for synthesizing colanic acids, resulting in attenuation of age-related metabolic changes. Credit: Meng Wang

A team of researchers has found a way to turn the bacteria living in the digestive tracts of animals into factories that can produce compounds that promote longevity in their hosts—showing a potential new drug development strategy.

Janelia Senior Group Leader Meng Wang and her team study longevity and were interested in seeing how they could transfer their research findings about longevity-promoting compounds into practical applications.

One idea they had was to induce the body’s gut microbiota—a collection of bacteria in th...

Gyromorphs merge order and disorder to deliver unprecedented light-blocking power for next-generation photonic computers. Researchers engineered “gyromorphs,” a new type of metamaterial that combines liquid-like randomness with large-scale structural patterns to block light from every direction. This innovation solves longstanding limitations in quasicrystal-based designs and could accelerate advances in photonic computing.

Researchers are exploring a new genera...

The sun produces more power than 100 trillion times humanity’s entire electricity generation. In orbit, solar panels can be eight times more productive than their Earth-bound counterparts, generating energy almost continuously without the need for heavy battery storage. These facts have led a team of Google researchers to ask what if the best place to scale artificial intelligence isn’t on Earth at all, but in space?

Project Suncatcher, Google’s latest space mission, envisions constellations of solar-powered satellites equipped with processors and connected by laser-based optical links...
