Walking with atoms—chemical bond making and breaking recorded in action

Ever since it was proposed that atoms are building blocks of the world, scientists have been trying to understand how and why they bond to each other. Be it a molecule (which is a group of atoms joined together in a particular ...

Laser pulse creates frequency doubling in amorphous dielectric material

Researchers have demonstrated a new all-optical technique for creating robust second-order nonlinear effects in materials that don't normally support them. Using a laser pulse fired at an array of gold triangles on a titanium ...

New class of crosslinker-free nanofiber biomaterials from Hydra nematocyst proteins

Nematocysts are stinging organelles of cnidarians that have remarkable mechanical properties to undergo 50 percent volume changes during explosive exocytosis (process by which cells excrete waste and large molecules), while ...

How rattlesnakes' scales help them sip rainwater from their bodies

During storms in the southwestern U.S., some rattlesnakes drink rain droplets from scales on their backs. This unusual behavior could help them survive in a desert environment with infrequent rain. Now, researchers have figured ...

Nearly quantized conductance plateau of vortex mode in an iron-based superconductor

When a semiconducting nanowire is coupled to a superconductor, it can be tuned to topological quantum states thought to host localized quasiparticles known as Majorana Zero Modes (MZM). MZMs are their own antiparticles, with ...

Portraits of particulate matter

On solar farms in particularly dusty places in the world, like the Arabian Peninsula and parts of India and China, air pollution costs the solar energy industry tens of billions of dollars annually. As particles settle out ...
