- Scientists proved that lasers can be used to harness materials into a reflective surface. Some scientists ask: Can a space mirror be far away?
- Thinking heavy thoughts? Scientists have just put people on a balance and shown that the brain briefly gains blood — becoming a bit heavier — while concentrating.
- Scientists occasionally describe the dog paddle as a “trot,” but that’s not right. When dogs swim, their complicated leg motions look more like a frantic run.
- Astronomers may have finally figured out why predictions of the amount of matter in the universe don’t match observations. A huge amount may hide in the gas clouds that surround galaxies.
- Head movements play an important role in successfully tracking lightning-fast incoming pitches.
- A supernova first spotted in 1987 produced a huge cloud of space dust. Astronomers are now finding clues in it to how stars formed in the early universe.
- The nicotine in tobacco that poisons some creatures can also act as a chemical defense — at least for some caterpillars. The bad breath it gives these insects repels natural predators, such as spiders.
- Electroconvulsive therapy is used to treat severe depression, but the electrical jolt it sends into the brain also may erase bad memories.
- When squished between two diamonds and zapped by a laser, salt’s atoms can link up in unexpected ways.
- The outdoor dust that dogs drag in contains a mix of microbes that helped mice fend off allergic reactions and viral infections.
