We summarize the week's scientific breakthroughs every Thursday.
- Tech
With two robotic fingers, humans get a helping hand
Mechanical fingers grasp like the real thing.
- Tech
Small lies in social networks may keep society running
Lying in social networks could have adverse, as well as beneficial, effects depending on the severity of the deception.
- Materials Science
Weird materials could make faster computers
Topological insulators could speed up how computers switch between 1s and 0s.
- Life
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.
- Tech
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.
- Quantum Physics
Commercial quantum computer fails to impress in new test
Fifteen million dollar D-Wave machine runs no faster than traditional computer in head-to-head challenge.
- Tech
Robo-fly steadies flight with onboard sensor
Scaling a robot to the size of a fly and stabilizing its flight with onboard sensors offers clues to how live insects stay steady in mid-air.
- Life
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.
- Tech
Scientists struggle to find signals in the noise
Even in a simple system like email, detecting the signal from the noise is not always easy. It can be even more difficult separating a dazzling discovery from dust or whether a breast mass is cancerous or benign.
