Scientists take key step toward custom-made nanoscale chemical factories: Researchers create new function in tiny protein shell structures
Science Daily / Posted 4 days ago
Scientists hope to tailor this new use to produce high-value chemical products, such as medicines, on demand. The sturdy nanocompartments, which are polyhedral shells composed of triangle-shaped sides and resemble 20-sided dice, are formed by... Read more

Scientists take key step toward custom-made nanoscale chemical factories
PhysOrg / Posted 6 days ago
The shell of a bacterial microcompartment (or BMC) is mainly composed of hexagonal proteins, with pentagonal proteins capping the vertices, similar to a soccer ball (left). Scientists have engineered one of these hexagonal proteins, normally devoid... Read more

Coupling two 'tabletop' laser-plasma accelerators: A step toward ultrapowerful accelerators
PhysOrg / Posted 9 days ago
Schematic of the first experiment to achieve staging of laser plasma accelerators (LPAs) with independent laser pulses: a pulse from laser 1 (at left) creates a plasma wakefield in the stage 1 LPA, a gas jet. The resulting electron beam is focused by... Read more

Study shows how calcium carbonate forms composites to make strong materials such as in shells and pearls
PhysOrg / Posted 1 months ago
When calcium carbonate crystallizes into hard shells, it incorporates soft bits of proteins to add strength. Research done in the lab shows how this might happen, and why it works. Credit: Wikipedia/ Public Domain Seashells and lobster claws are hard... Read more
