Phys.org / These blazing blue explosions may be born when a compact dead star slams into a Wolf-Rayet star

Luminous fast blue optical transients (LFBOTs) are among the universe's brightest and fastest explosions but their origin is not completely understood. A new study takes a closer look at the galaxies they occur in, offering ...

Phys.org / Sulfur-rich Mercury magmas behave differently than Earth's do

Mercury is a small, rocky planet about which researchers know relatively little. Two missions, taking readings as they passed over the planet, have revealed that Mercury is covered by an iron-poor and sulfur-rich crust. It ...

Phys.org / A light-controlled 'muscle' could give synthetic cells a new way to move

Engineers interested in creating artificial cells to deliver drugs to unhealthy parts of the body face a key challenge: for a cell-like system to move, change shape, or divide, it needs a way to generate force on command.

Phys.org / How tiny voids could make fusion targets more stable under powerful shockwaves

Picture two materials sandwiched together. The boundary between them may appear flat, but, in reality, it is full of tiny bumps and dents. Suddenly, the materials are hit with a shockwave. If that wave hits a bump in the ...

Phys.org / There's a range of magic angles to study superconductivity in a twisted 2D semiconductor

Last year, tungsten diselenide (WSe2) had its magic moment. Two independent research groups discovered "magic angles" at which two atom-thin layers of the unique semiconductor, when twisted relative to one another into what's ...
