Making Bubbles in Magma

When bubbles form in magma deep below the earth, volcanic eruptions follow. Scientists believe this happens when decompression of the magma allows volatile compounds to come out of solution and form bubbles--just as opening a bottle of seltzer allows carbon dioxide to bubble out. But a new study indicates that decompression may not be the only source of bubbles. (Image credit: volcano - A. Bonnerdeaux, experiment - O. Roche et al.; research credit: O.

How silver iodide triggers ice formation at the atomic level

No one can control the weather, but certain clouds can be deliberately triggered to release rain or snow. The process, known as cloud seeding, typically involves dispersing small silver iodide particles from aircraft into clouds. These particles act as seeds on which water molecules accumulate, forming ice crystals that grow and eventually become heavy enough to fall to the ground as rain or snow. Until now, the microscopic details of this process have remained unclear. Using high-resolution microscopy and computer simulations, researchers at TU Wien have investigated how silver iodide interacts with water at the atomic scale. Their findings, published in Science Advances, reveal that silver iodide exposes two fundamentally different surfaces, but only one of them promotes ice nucleation. The discovery deepens our understanding of how clouds form rain and snow and may guide the design of improved materials for inducing precipitation.

Women wear the trauma of other creatures around their necks, in an attempt to put a pall on their own. Adorn the self to be adored. What if we fail? What if we are failures at love?

Seeding Clouds With Wildfire

Raging wildfires send plumes of smoke up into the atmosphere; that smoke is made up of tiny particles that can serve as seeds -- nucleation sites -- where water vapor can freeze and form clouds. To understand wildfire's effect on cloud growth, researchers sampled air from the troposphere (the atmosphere's lowest layer) both in and around wildfire smoke. (Image credit: K.

"Microscopic World"

So many natural processes take place right in front of us, but they're too small and too fast to see. Here, the Beauty of Science team puts some of those processes -- crystallizing solids, nucleating bubbles, and more -- front and center. The shapes and colors draw you in, inviting you to engage with science we see daily but rarely appreciate. (Video and image credit: Beauty of Science) Read the full article
