We summarize the week's scientific breakthroughs every Thursday.
- Quantum Physics
Milestone algorithm runs on quantum computer
An algorithm proposed two decades ago that demonstrated the benefit of using quantum mechanics to solve certain problems has finally been run on a quantum computer.
- Tech
‘Micro-scallop’ takes a stroke toward swimming in blood
A tiny device that looks like a scallop flaps its way through viscous fluids, something that has been a challenge in the past.
- Neuroscience
A species of invention
From early humans painting on cave walls to modern-day engineers devising ways to help people move better, the drive to innovate is simply part of who humans are.
- Math
Spirals inspire walking aids for people with disabilities
Long admired for their beauty, spirals have inspired a shoe that may help disabled people walk. The shapes make for a better crutch and an entertaining skateboard as well.
- Tech
Sheath helps ‘aqua-hamster’ survive underwater
Scientists hoped a membrane invented in 1964 would let submarines pull air from seawater.
- Science & Society
Asteroids closer to home may get us to Mars
NASA should abandon its attempt to bring a space rock into lunar orbit and instead scrutinize ones already whizzing by Earth, one scientist argues.
- Tech
New microscope gives clear view inside cells
By splitting beams of light, a new microscopy technique can capture activity inside a cell.
- Science & Society
E-commerce sites personalize search results to maximize profits
Travel and retail websites alter search results depending on whether consumers use smartphones or particular web browsers.
- Planetary Science
‘Mars Rover Curiosity’ chronicles robot’s journey
Engineer Rob Manning recounts the decade of victories and setbacks that preceded Curiosity’s landing on Mars.
- Computing
Computer program reveals artists’ influences
The algorithm can figure out a particular painting’s style — whether it’s abstract, impressionist or Baroque, for example — and tease out possible connections among artists.
- Animals
Rattlesnakes tutor robot on dune climbing
Snakes sidewinding up sand inspire design improvements for robots navigating treacherous slopes.
- Tech
Microscopy techniques win Nobel Prize in chemistry
The award goes to three scientists who developed fluorescence microscopy, which allows researchers to see single molecules just a billionth of a meter across.
