Bacteria’s bodies do whirlies to help them swim
Kidney-shaped Caulobacter crescentus bacteria swim with both their corkscrew propellers called flagella and their bodies, scientists say.
- Tech
Wax-coated plastic morphs between soft and stiff
Heat-controlled materials could serve as skeleton for shape-shifting robots.

1960s research paid off in automotive safety
Scientists in 1964 were studying shatterproof glass, which was mandated just a couple of years later.
- Psychology
Online causes may attract more clicks than commitments
Online awareness campaigns can make people feel they’ve contributed to a good cause, but social scientists say the tangible benefits of such efforts may be small.

Genetic mutation quenches quantum quirk in algae
Studying algae that can and cannot use quantum coherence to harvest light could lead to better organic solar cells and quantum-based electronic devices.
- Physics
Energy-efficient laser works at room temperature
A room-temperature polariton laser, which requires little electricity, could improve electronics and medical devices.
