A patch studded with tiny needles may help heart attack survivors recover
A bandage that sticks to the surface of the heart exudes proteins and other molecules that help muscle cells grow.
- Earth
A new algorithm could help protect planes from damaging volcanic ash
A computer program that tracks the temperature and height of clouds in the atmosphere could keep planes away from volcanic ash.
- Tech
A new airplane uses charged molecules, not propellers or turbines, to fly
A small aircraft prototype is powered by ionic wind flowing in one direction and pushing the plane in the other.

How Twitter bots get people to spread fake news
Automated bot accounts on Twitter help spread misinformation by strategically encouraging people to make it go viral.
- Microbes
Mini ‘solar panels’ help yeast shine at churning out drug ingredients
Microbes equipped with light-harvesting semiconductor particles generate useful chemicals much more efficiently than ordinary microbes.
- Environment
Car tires and brake pads produce harmful microplastics
Scientists surveyed tiny airborne plastics near German highways and found that bits of tires, brake pads and asphalt make up most of the particles.
- Chemistry
