Electron microscopes are used to uncover the structure of proteins, like that of the COVID-19 spike protein used to develop vaccines. For nearly a century, scientists have known that phase shifting an electron beam could improve the method. They’ve finally found a reliable way to do it. #lasers

Atmospheric rivers move huge volumes of water across the globe, bringing long rainy days and sometimes causing major floods. Serena Scholz and Juan Lora explain how these rivers in the sky form and how climate change could extend their reach.

Even a small nuclear conflict could cause irreversible damage to global climate and food systems—but analysts considering the consequences of nuclear war often ignore those risks. #nuclearweapons

Willful ignorance of the global impact of nuclear warEven a limited nuclear war could disrupt the climate, ecosystems, and global food supplies. Nuclear strategies and decisions should be required to factor in those potential consequences.physicstoday.aip.org

Increased emissions from wildfires in the past decade have reversed earlier progress made in decreasing US surface-level ozone pollution, a new analysis finds.

The quantum world is full of counterintuitive phenomena. Using a vortex to scatter standing waves in water, researchers showed how classical fluids can serve as laboratories for visualizing quantum effects that may be much harder to observe in quantum systems. #BackScatter #quantum
