- Tech
Engineers consider liquid salt to generate power
A new type of power plant, a molten salt reactor, might provide electricity in a cleaner and safer way than current nuclear technology.
- Chemistry
Some 3-D printing can leave toxic taint
The ”ink” inside some 3-D printers can leave toxic traces. In tests, these chemicals harmed baby fish. But lighting could render the parts safer.
- Microbes
Slime cities
Biofilms are like tiny cities of bacteria — some harmless, others destructive. Scientists are learning how to keep these microscopic metropolises under control.
- Animals

Most species are rare. Some have always been rare. A problem develops when people are responsible for accelerating a species’ rarity to the point that extinction threatens.
- Physics
X-ray ‘eyes’
