Trapping light: a long lifetime in a very small place
Physicists have created a silicon nanocavity that allows light to be trapped 10 times longer than in other similarly-sized optical cavities. Nanocavities are key components of nanophotonics circuits.
Protein anchors help keep embryonic development “just right”
Findings on the cellular-level regulation of proteins called histones by lipid droplets, or “fat depots,” shines light on chromosome production – and possible manipulation of that process.
Better tissue healing with disappearing hydrogels
When stem cells are used to regenerate bone tissue, many wind up migrating away from the repair site, which disrupts the healing process. A new technique keeps the stem cells in place, resulting in faster and better tissue regeneration.
Experiment on earth demonstrates effect observed in space
Streaming jets of high-speed matter produce some of the most stunning objects seen in space. an experiment by French and American researchers using extremely high-powered lasers offers experimental verification of one proposed mechanism for creating them.
Progress made in developing nanoscale electronics
How can you reliably control the current that flows from one electrode to another in a circuit that is the width of a single molecule? The key, according to assistant professor of chemical engineering Alexander Shestopalov, is adding a second, inert layer of molecules.
Andes mountains formed by ‘growth spurts’
Scientists have long been trying to understand how the Andes and other broad, high-elevation mountain ranges were formed. New research by Carmala Garzione, professor of earth and environmental sciences, provides an explanation.
Video gamers’ aggression linked to frustration, not violent content
The disturbing imagery of videos games are often accused of fostering feelings of aggression in players. But a new study shows hostile behavior is linked to gamers’ experiences of failure and frustration during play—not to a game’s violent content.
First 3-D image of structure below Sierra Negra volcano created
Home to some of the most active volcanoes in the world, researchers now have a better picture of the subterranean plumbing system that feeds the Galápagos volcanoes.
Women, minority judicial nominees receive lower ratings
A new study suggests that the American Bar Association ‘s sometimes-controversial ratings systematically award lower ratings to minorities and women than to white or male candidates.
How stellar death can lead to twin celestial jets
How do spherical stars evolve to produce highly aspherical planetary nebulae? A Rochester professor and his undergraduate student have a new theory as to why.
