A new Durham University study has found that a giant impact may not be responsible for the formation of Jupiter’s remarkable “dilute” core, challenging a theory about the planet’s history.

Jupiter, the largest planet in our solar system, has a mystery at its heart. Unlike what scientists once expected, its core doesn’t have a sharp boundary but instead gradually blends into the surrounding layers of mostly hydrogen (a structure known as a dilute core).

How this dilute core formed has been a key question among scientists and astronomers ever since NASA’s Juno spacecraft first revealed its existence.

A previous study suggested that a colossal collision with an early planet containing half of Jupiter’s core material could have thoroughly ...

It’s a fact of life: Some people age better than others. Some ease into their 90s with mind and body intact, while others battle diabetes, Alzheimer’s or mobility issues decades earlier. Some can withstand a bad fall or bout of the flu with ease, while others never leave the hospital again.

New University of Colorado Boulder-led research, published in Nature Genetics, sheds light on why that is.

In it, an international team of co-authors identifies more than 400 genes associated with accelerated aging across seven different sub-types. The study reveals that different groups of genes underlie different kinds of disordered aging, a.k.a. frailty, ranging from cognitive decline to mobility issues to social isolation.

The findings lend support to what is known as the “geroscience ...

Numerous market analyses have shown that over the next five years, demand for lithium-ion batteries for everything from personal electric devices to grid-scale energy storage is expected to grow dramatically.

To meet this demand, battery manufacturing needs to be faster, cheaper, more dependable, less energy-intensive and less wasteful. A key part of lithium-ion battery manufacturing with significant room for improvement is the processing and fabrication of electrodes.

To facilitate advances in this area, researchers at the U.S...
