Letters to the Editor
For this issue, the editors selected the 25 most important and intriguing science stories of the year. But online readers seemed to point to a different bunch, showing just how subjective such an exercise can be. While it’s difficult to gauge reader opinions based solely on letters, we can and do...

DALLAS — Nobody seems to be noticing, but this month is the 50th anniversary of using the term “black hole” to describe the bottomless pits of outer space.That’s probably because the traditional story gives the year of the term’s birth as 1967, when John Archibald Wheeler used it during a lecture in New York City in December of that year.Wheeler, who died in 2008, said the term...

News in Brief
Koalas have a newly discovered extra set of vocal cords that allows males to hit notes 20 times lower than expected.Because the sizes of an animal’s voice box and its flapping vocal cords dictate the range of pitches an animal can make, a typical 8-kilogram koala should stick near the soprano section. But the male’s sexy mating songs, which to humans sound like a string of belches and snorts, dip...

Last year it was easy to choose a story to lead our annual Top 25 list. The discovery of the Higgs boson was a watershed moment, ending a decades-long quest by thousands of physicists to fully describe the subatomic realm.This year, nothing so momentous came to pass. But science isn’t just about dramatic announcements and tremendous technical feats. Anyone who reads Science News...

When ichthyosaurs were alive, some of the dolphin-like sea creatures may have had dark-colored skin covering their entire bodies.Many ocean-dwelling animals are darker on their upward-facing side and lighter on their underside. But chemical analyses of dark traces in fossilized tissue show that a 190-million- to 196-million-year-old ichthyosaur had skin pigments that made the animal uniformly...
