X-ray analysis reveals the inner life of leaves while advancing engineering efforts to reduce 'crop sweat'

In the Midwestern summer, humans and plants have to breathe through the heat and humidity. Researchers hope that a retooled crop plant—one with an improved ventilation system within its leaves—could thrive while avoiding ...

'Flying focus' laser overcomes key limitation in plasma-based particle accelerators

In a new Nature Physics study, researchers accelerated electrons to more than twice the energy predicted by the traditional dephasing limit for laser-plasma accelerators operating over the same distance. This was made possible ...

Silver nanocatalysts switch reaction sites between power generation and hydrogen production

For the first time, researchers have discovered that the same silver (Ag) nanocatalyst operates at different reaction sites depending on whether a solid oxide cell is generating electricity or producing hydrogen. This finding ...

Spacecraft observations may conceal how particles really move through near-Earth space

High-energy particles in Earth's radiation belt can appear to spread out randomly, even when they are moving in a "predictable" way. This is because spacecraft observations naturally blur the fine-scale structure of the particle ...
