When a virus enters a cell, its top priority is to replicate its genome rapidly, creating new viruses to infect elsewhere. The host has the opposite priority: to destroy the virus, ideally before it can do any harm. Biology ...

Curiosity spent the week continuing to climb her way through the layers of Mount Sharp, exploring the sedimentary rock strip chart of Martian history. The rover has reached a layer where the science team had spotted a possible ...

A new Concordia study has demonstrated a greener way to produce an important class of catalytic materials with promising potential for cleaner energy technologies that rely more on acoustic energy than water and chemicals. ...

A scientific collaboration between the University of Bath (UK) and the UMass Chan Medical School (U.S.) has determined how a specific type of white blood cell—neutrophils—moves through the body.

Quadruped robots, which walk on four legs, are increasingly used for tasks such as inspection, transportation and search-and-rescue operations. However, their repeated leg movements consume far more energy than the rolling ...

When catastrophic wildfires capture global headlines, such as the unprecedented blazes sweeping through southern Europe this summer or the devastating 2019–20 "Black Summer" in Australia, they are almost always preceded by ...

Scorching summer temperatures have disrupted life for millions of Europeans, but for winegrowers in Italy and France who are harvesting their grapes unusually early, the hot weather offers pros as well as cons.

One year after unveiling a first-of-its-kind "microwave brain" microchip capable of computing on ultrafast data and wireless signals, researchers from the Cornell Duffield College of Engineering have shown how the chip can ...

A new study published in Nature Physics reports the first direct experimental evidence of a Floquet topological state, a novel light-induced phase of matter that, until now, has existed only on paper and in simulations. Topological ...

A 113-million-year-old marine murder mystery may finally be solved. Using chemical clues locked inside microscopic fossils, Northwestern University scientists found evidence that ocean acidification drove one of the largest ...

As NASA's Curiosity rover recently began climbing a Martian valley nicknamed "Valle Grande," it sent back images that were a familiar sight to mission scientists: honeycomb-like textures called polygonal fractures, each about ...

As the world's population grows and industry expands, many countries in Africa, the Middle East and Southeast Asia are facing a freshwater scarcity crisis. Finding sustainable ways to produce clean water has become an urgent ...
