A research team led by Yang Lu from the Department of Mechanical Engineering at the Faculty of Engineering, The University of Hong Kong (HKU), has uncovered the microscopic physical nature of ultralarge elasticity in covalent ...

All living things have a fleet of tiny copy machines that turn instructions from DNA into RNA molecules responsible for helping build proteins that keep organisms alive. One of those nanoscale machines, called eukaryotic ...

Insects rely on a wide range of strategies to sense their surroundings and communicate with their peers. Fireflies (Lampyridae) and some related beetles are known for their ability to produce visible light through chemical ...

A two-headed molecule designed by Stanford Medicine researchers hijacks one of the most common protein drivers of B-cell lymphoma, flipping it from its role as a promoter of cell growth into an arbiter of cell death. In mice, ...

As transistors inside microchips continue to shrink, the metal wiring that connects them is becoming a growing obstacle to faster, more energy-efficient chips. Narrower wires have greater electrical resistance, while smaller ...

Researchers have created an interactive map identifying 1.8 million individual trees in New York City, using a new approach that could optimize the placement of trees for cooling in cities around the world.

So far, most of the minerals found on Mars tell a story of lava poured out by ancient volcanoes, followed by long stretches in which water trickled through and slowly reshaped the rock. However, some rocks scattered across ...

Biologists, zoologists and psychologists have been trying to trace the origins of human language for centuries. One well-known theory, known as the social brain hypothesis, suggests that increasingly complex social lives ...

Quantum sensors, devices that collect measurements by exploiting quantum-mechanical phenomena, could potentially detect extremely weak magnetic, gravitational and electromagnetic signals with greater sensitivity than classical ...

Scientists analyzed the genomes of gut microorganisms from an extensive population of 875 wild house mice (Mus musculus) collected from farms in Germany. They searched for genes responsible for resistance to common antibiotics ...

Cataract surgery—one of the most common operations paid for by Medicare—typically leaves enrollees owing a few hundred dollars. Some patients pay more to have their vision corrected during the procedure.

Fusion reactors, devices that generate energy by fusing light atomic nuclei at extremely high temperatures, could contribute to ongoing efforts aimed at producing electricity more sustainably. The extreme environment inside ...
