An international team of researchers announced in Switzerland on Wednesday that an experiment on the International Space Station may have seen hints of something called dark matter. The finding could be a milestone in the decades-long search for the universe's missing material.
Only a tiny sliver of stuff in the universe is visible to scientists; the rest is dark matter. Researchers don't know what it is, but they know it's there. Its gravity pulls on the things we can see.

With one-quarter of adults over age 45 taking cholesterol-lowering statin drugs, it figures that more than a few people would have trouble sticking with the program.
More than a few, actually.
A big new study of statin use in the real world found that 17 percent of patients taking the pills reported side effects, including muscle pain, nausea, and problems with their liver or nervous system.
That's a lot higher than the 5 to 10 percent reported in the randomized controlled trials that provided evidence for regulatory approval of the medicines.
Hagel has ordered the Pentagon to take a hard look at how many soldiers and sailors it needs and what types of weapons it buys.
