Electrical imbalances at grain boundaries help explain solid-state battery failure

Next-generation batteries that use new electrolyte materials could achieve far higher energy density than today's lithium-ion batteries, without many of the safety concerns. But advanced batteries, such as those that use solid or almost-solid electrolytes, have been plagued by th

Preparing birds for life in the wild: New technique boosts survival after release

Every year, thousands of parrots confiscated from the illegal wildlife trade arrive at rehabilitation centers across Latin America. For many of these birds, rescue centers can provide safety but not necessarily a path back to the wild.

Modeling reveals Sydney's 1789 smallpox outbreak killed as many as 220,000 indigenous Aust

Groundbreaking modeling has revealed that as many as 220,000 Indigenous Australians died in a devastating 1789 smallpox outbreak that originated in Sydney, tracing its origins to the First Fleet. Soon after British ships arrived, smallpox swept through First Nations communities i

Africa's wildlife laws follow a colonial model that separates people and animals: Why it's

Africa is home to many iconic national parks and marine reserves, such as Virunga in the Democratic Republic of the Congo, Niokolo-Koba in Senegal, Kruger National Park in South Africa and Serengeti National Park in Tanzania. Many of them were established during the colonial era,

Newly identified marine bacterial enzyme opens new route to building bioactive compound li

Many important medicines and agricultural compounds have origins in natural products made by microorganisms. One such compound is prodigiosin, a vivid red pigment produced by certain bacteria. Beyond its color, prodigiosin and related compounds known as prodiginines have attracte

Tiny Jurassic bird reveals a key step in bird evolution

The transition from a lumbering, heavy dinosaur body to the flight-adapted bird body plan is one of many fascinating episodes in evolutionary history. Working out how this massive transformation took place relies heavily on fossil records, especially of transitional species. A st

How cells keep genomic hitchhikers under control

Much of the genome is made up of repetitive DNA sequences that trace back to ancient mobile elements, many of which have lost their ability to copy themselves into new locations but can still cause problems if they become active again at the wrong time. Now, two studies published

The language of play: Hyenas use facial expressions and vocalizations to de-escalate

Scientists observed spotted hyenas (Crocuta crocuta) playing in the wild and found that their precise, sophisticated communication is on par with that of many primate species. Hyenas play and romp with one another at all stages of life. Although juveniles play more frequently tha

Scientists used AI to crack one of water's biggest mysteries

Water’s odd behavior becomes even more dramatic when it is supercooled, but scientists have struggled to compare the many different ways of describing its microscopic structure. Researchers at the University of Osaka used an AI model trained on computer simulations to evaluate 16

Heidelberg physicists just united two opposing quantum theories

A new quantum theory bridges two rival models of how impurities behave inside many-particle systems, resolving a problem that has challenged physicists for decades. The findings could reshape experiments on ultracold atoms, semiconductors, and other exotic forms of quantum matter
