A whitish, gray patch that sometimes appears in the night sky alongside the northern lights has been explained for the first time by researchers at the University of Calgary.

The article, which was published on Dec. 30 in the journal Nature Communications, explores a “structured continuum emission” that’s associated with aurora borealis.

“You’d see this dynamic green aurora, you’d see some of the red aurora in the background and, all of a sudden, you’d see this structured—almost like a patch—gray-toned or white toned-emission connected to the aurora,” says Dr. Emma Spanswick, Ph.D...

Beneficial gut microbes and the body work together to fine-tune fat metabolism and cholesterol levels, according to a new preclinical study by investigators from Weill Cornell Medicine and the Boyce Thompson Institute at Cornell University’s Ithaca campus.

The research is published in the journal Nature.

The human body has co-evolved with the beneficial microbes that live in the gut (termed the microbiota), resulting in mutually favorable relationships that aid in the d...

We often take for granted just how ubiquitous Wi-Fi has become over the past two decades, explains Northeastern University electrical and computer engineering professor Francesco Restuccia, who is also a member of the Institute for the Wireless Internet of Things.

Wi-Fi provides wireless connectivity to more than 20 billion devices around the globe, including smartphones, laptops, game consoles, and smart TVs. And for most people, Wi-Fi works so smoothly it almost feels magical.

“It’s one of the most pervasive technologies ever invented by mankind,” Restuccia says. “We seamlessly utilize Wi-Fi every day without even knowing we are...

Stars are born in clouds of gas and dust, making it difficult to observe their early development. But researchers at Chalmers have now succeeded in simulating how a star with the mass of the sun absorbs material from the surrounding disk of material—a process called accretion.

The researchers simulated four stars with the same mass but with v...
