The awe-inspiring process of cell division can turn a fertilized egg into a baby—or a cancerous cell into a malignant tumor. With so much at stake, nature keeps it tightly controlled in a process called the cell cycle that ...
Astronauts driving a vehicle around the landscape of the moon must not only face dangers related to zero gravity and falling into craters, but also the problem of extreme fluctuations in temperature. The lunar environment ...
Biomedical engineers at Duke University have developed a silk-based, ultrathin membrane that can be used in organ-on-a-chip models to better mimic the natural environment of cells and tissues within the body. When used in ...
New research led by Lia Siegelman, a physical oceanographer at UC San Diego's Scripps Institution of Oceanography, shows that the roiling storms at the planet Jupiter's polar regions are powered by processes known to physicists ...
A single universal equation can closely approximate the frequency of wingbeats and fin strokes made by birds, insects, bats and whales, despite their different body sizes and wing shapes, Jens Højgaard Jensen and colleagues ...
Spacecraft electronics operate under extreme conditions, facing issues like microgravity, thermal cycling, and space radiation. These factors necessitate robust thermal management solutions to maintain the functionality and ...
As we discover more and more exoplanets—and the current total is in excess of 5,200—we continue to try to learn more about them. Astrobiologists busy themselves analyzing their atmospheres searching for anything that ...
Millions of people live near active volcanoes that are constantly monitored for signs of an impending eruption. When one occurs, scientists and governments rely on data to estimate the extent of the possible damage, informing ...
For years, various models have been developed to describe an important class of mixing effects that occur, for example, in the flow in a chemical reactor. Experimental validation, however, has lagged far behind due to the ...
Due to their stability and resistance to water and grease, PFAS chemicals (short for per- and polyfluoroalkyl substances) are used in a wide range industries, but they are harmful to health and the environment. Membranes ...
