We summarize the week's science breakthroughs every Thursday.
- 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.
- Tech
Exoskeleton helps paraplegic kick off World Cup
A paralyzed person wearing a brain-controlled robotic exoskeleton has made the first kick at the 2014 soccer World Cup.
- Tech
Self-driving cars are not a thing of the past
Engineers have not given up on self-driving cars. The focus has shifted from a mechanical approach to using batteries and GPS.
- Animals
See your lawn through a bird’s eyes with YardMap
A new web tool lets you map your outdoor spaces and wildlife habitat, helping scientists understand how birds use urban and suburban spaces.
- Life
A new twist on a twist
Nature abounds with perfect helices. They show up in animal horns and seashells, in DNA and the young tendrils of plants. But helix formation can get complicated: In some cases, the direction of rotation can reverse as a helix grows.
- Tech
Lasers heal damaged rodent teeth
Handheld laser spurs stem cells into action, regrowing dentin in drilled teeth.
