Eating a high-fat diet containing a large amount of oleic acid—a type of fatty acid commonly found in olive oil—could drive obesity more than other types of dietary fats, according to a study published in the journal Cell Reports.

The study found that oleic acid, a monounsaturated fat associated with obesity, causes the body to make more fat cells. By boosting a signaling protein called AKT2 and reducing the activity of a regulating protein called LXR, high levels of oleic acid resulted in faster growth of the precursor cells that form new fat cells.

“We know that the types of fat that people eat have changed during the obesity epidemic...

Largest map of the universe announced revealing 800,000 galaxies, challenging early cosmos theories

In the name of open science, the multinational scientific collaboration COSMOS on Thursday released the data behind the largest map of the universe. Called the COSMOS-Web field, the project, built with data collected by the James Webb Space Telescope (JWST), consists of all the imaging and a catalog of nearly 800,000 galaxies spanning nearly all of cosmic time. And it’s been challenging existing notions of the infant universe.

“Our goal was to construct this deep field of space ...

Boise State University researchers have unveiled a cutting-edge approach to manufacturing flexible hybrid circuits—reducing costs, waste, and environmental impact. Their work leverages the properties of laser-induced graphene and was recently featured on the cover of Advanced Materials Technologies.

Laser-induced graphene uses a single-step laser manufacturing process that converts carbon-rich mater...

The Big Bang is often described as the explosive birth of the universe—a singular moment when space, time and matter sprang into existence. But what if this was not the beginning at all? What if our universe emerged from something else—something more familiar and radical at the same time?

In a new paper, published in Physical Review D, my colleagues and I propose a striking alternative. Our calculations suggest the Big Bang was not the start of everything, but rather the outcome of a gravitational crunch or collapse that formed a very massive black hole—followed by a bounce inside it.

This idea, which we call the black hole universe, offers a radically different view of cosmic origins, yet it is grounded entirely in known physics and observations.

Today’s standard cosmo...
