Nature inspires self-assembling helical polymer

Helical structures are ubiquitous across biology, from the double-stranded helix of DNA to how heart muscle cells spiral in a band. Inspired by this twisty ladder, researchers have developed an artificial polymer that organizes itself into a controlled helix.

Scientists create AI that 'watches' videos by mimicking the brain

Imagine an artificial intelligence (AI) model that can watch and understand moving images with the subtlety of a human brain. Now, scientists have made this a reality by creating MovieNet: an innovative AI that processes videos much like how our brains interpret real-life scenes as they unfold over time. Read more ›

Pups of powerful meerkat matriarchs pay a price for their mom's status

In meerkat society a dominant female is in charge, growling, biting, pushing and shoving to keep others in line. The matriarch's bullying behavior is fueled by high levels of testosterone that can surge to twice those of her male counterparts when she's pregnant. But while testosterone gives her a competitive edge and helps her keep the upper hand, it can also take a toll on the health of her developing... Read more ›

What motivates Americans to eat less red meat?

Limiting red meat consumption is key to a sustainable and healthy diet, yet Americans are among the world's largest consumers of red meat. A new study reveals the demographics of American adults who choose not to eat red meat and finds that environmental concerns may matter more to them than health risks. Read more ›

Virtual fences are a pollinator-friendly option for ranchlands

Fences are an effective stationary method of corralling livestock, but their sharp borders can create sudden changes in native grassland vegetation and the pollinators and birds that live there. Virtual, GPS-based fences may be the nature-friendly future of fencing, creating more natural grassland habitat, finds new research. Read more ›

Rotavirus vaccine is safe for use in NICU babies, study suggests

Researchers found that transmission of rotavirus vaccine strains in a neonatal intensive care unit (NICU) is rare and without clinical consequences, strongly suggesting that giving the rotavirus vaccine to eligible infants during their hospitalization provides immune benefits that outweigh any risks. The findings could serve as the basis for a change in clinical practice. Read more ›

The last missing piece of silicon photonics

Scientists have developed the first electrically pumped continuous-wave semiconductor laser composed exclusively of elements from the fourth group of the periodic table -- the 'silicon group'. Built from stacked ultrathin layers of silicon germanium-tin and germanium-tin, this new laser is the first of its kind directly grown on a silicon wafer, opening up new possibilities for on-chip integrated photonics.
