Three nano glass spheres cling to one another. They form a tower-like cluster, similar to when you pile three scoops of ice cream on top of one another – only much smaller. The diameter of the nano cluster is ten times smaller than that of a human hair. With the help of an optical device…
As Greenland’s ice retreats, it’s fueling tiny ocean organisms. To test why, scientists turned to a computer model out of JPL and MIT that’s been called a laboratory in itself. Runoff from Greenland’s ice sheet is kicking nutrients up from the ocean depths and boosting phytoplankton growth, a new NASA-supported study has found. Reporting in…
Researchers taking the first-ever direct measurement of atom temperature in extremely hot materials inadvertently disproved a decades-old theory and upended our understanding of superheating. It’s notoriously difficult to take the temperature of really hot things. Whether it’s the roiling plasma in our Sun, the extreme conditions at the core of planets or the crushing forces…
How can the behavior of elementary particles and the structure of the entire universe be described using the same mathematical concepts? This question is at the heart of recent work by the mathematicians Claudia Fevola from Inria Saclay and Anna-Laura Sattelberger from the Max Planck Institute for Mathematics in the Sciences, recently published in the…
Millions of Americans have altered vision, ranging from blurriness to blindness. But not everyone wants to wear prescription glasses or contact lenses. Accordingly, hundreds of thousands of people undergo corrective eye surgery each year, including LASIK — a laser-assisted surgery that reshapes the cornea and corrects vision. The procedure can result in negative side effects,…
