Chemists discover why photosynthetic light-harvesting is so efficient
The disorganized arrangement of the proteins in light-harvesting complexes is the key to their extreme efficiency.
3Q: Exploring the universe’s “first light”
After the James Webb Space Telescope’s first year in service, astronomers are awash in new observations that illuminate the oldest stars and galaxies.
Using reflections to see the world from new points of view
A new computer vision system turns any shiny object into a camera of sorts, enabling an observer to see around corners or beyond obstructions.
Scientists map gusty winds in a far-off neutron star system
The 2D map of this “disk wind” may reveal clues to galaxy formation.
Resilient bug-sized robots keep flying even after wing damage
New repair techniques enable microscale robots to recover flight performance after suffering severe damage to the artificial muscles that power their wings.
