In our solar system, an asteroid orbits the Sun in the opposite direction to the planets. It takes 12 years to make one complete orbit around the Sun. The asteroid with the retrograde co-orbit was identified by Helena Morais, a professor at São Paulo State University's Institute of Geosciences & Exact Sciences, in Brazil. In partnership with Fathi Namouni at the Côte d'Azur Observatory in France, Morais developed a general theory on retrograde co-orbitals and retrograde orbital resonance.
UC biologist helps decode the structural complexities of male butterfly ejaculate and co-evolving female reproductive tract. Findings from these biochemical relationships may help unlock certain mysteries of human infertility.
Researchers from the Naval Research Laboratory use gated digital holography methods to develop foliage penetrating LiDAR that can survey obscured ground.
After 12 years observing black holes at the center of an amalgam of ancient galaxies, a multi-institution team, including Stanford's Roger Romani, may have recorded the smallest-ever movement of an object across the sky.
Scientists at UC Berkeley and UC Riverside have demonstrated a way to edit the genome of disease-carrying mosquitoes that brings us closer to suppressing them on a continental scale.
Many geckos inhabit trees, often living high in the canopy. Relying on their incredible adhesive strength to help them break their fall, they jump from trees, and land on leaves or smooth tree trunks. A team of researchers led by a biologist at the University of California, Riverside now reports that the gecko adhesive system may reach its functional limits in extreme situations, such as when a gecko falls/jumps from the canopy of a rainforest.
The ability to walk well is a sign of independence and good health for older adults, for example, and it may be affected by the use of multiple medications. Although healthcare providers know that some treatments can slow or hamper an older person's ability to walk, little is known about the effects of polypharmacy on walking while performing other tasks, like talking. In a new study, researchers examined how polypharmacy affected walking while talking.
Images made with the continent-wide Very Long Baseline Array detect the orbital motion of two supermassive black holes as they circle each other at the center of a distant galaxy.
The silver nanowires are held together in the polymer so that they touch, and as long as the polymer doesn't dissolve, the nanowires will form a path to conduct electricity similar to the traces on a circuit board.
A new study by researchers at Dartmouth has found that adolescents living in medical marijuana states with a plethora of dispensaries are more likely to have tried new methods of cannabis use, such as edibles and vaping, at a younger age than those living in states with fewer dispensaries.
