A promising material for conducting electrical current without resistance at a relatively high temperature has passed a crucial test. New magnetic measurements, detailed by German physicists in a study posted online June 26 at arXiv.org, indicate that pressurized hydrogen sulfide is a superconductor at roughly 200 kelvins.

Stopping to smell the roses might be a letdown — and now researchers know why.
The sweet-smelling flowers craft their scent using a surprising enzyme, previously thought to help prune genetic errors, researchers report July 3 in Science. That enzyme — and potent aroma — is missing in many roses bred for...
The Science Life
If the moon is up, there’s a good chance Joseph Taylor is on his ham radio, using a homemade antenna in his backyard to bounce signals off the moon’s pockmarked face. It’s a skill Taylor began cultivating in 2003, shortly before he retired from Princeton University, where he used radio waves to probe the secrets of pulsars, the spinning, magnetized neutron stars that emit bursts of radiation...
Warren Chan helped invent a research field and then watched it nearly die.
The chemist and biomedical engineer at the University of Toronto specializes in quantum dots, tiny semiconductor particles that glow in a rainbow of colors when zapped with a laser. Fifteen years ago, quantum dots were all the rage....

Math, science, history — science writer Dave Zobel unravels the mysteries in The Science of TV’s the Big Bang Theory.
Hopefully after next week we will never again hear about Deflategate, the controversy surrounding the role of underinflated footballs in January’s conference championship game between the New England Patriots and the Indianapolis Colts. On June 23, the NFL commissioner will hear the appeal of Patriots quarterback Tom Brady’s four-game suspension, one of the punishments that resulted from the...

Summer vacations are so close one can almost smell the smoke from marshmallow-toasting campfires, bonfires on the beach, and, of course, classic backyard barbecues. What’s even better: Those imminent holiday blazes may require little thought, according to a new study.
Humans tend to build very efficient fires, perhaps unwittingly, says physicist Adrian Bejan of Duke University. And he...
Sailors have long told remarkable stories of monstrous, ship-damaging waves that seem to come out of nowhere. But new research analyzing these rogue waves in and out of the ocean reveals that at least some of them are foreseeable.
A telltale set of conditions precedes the appearance of bright flashes in tabletop laser experiments that are similar to...

Neandertals knew how to accessorize. Eight 130,000-year-old eagle talons unearthed in Croatia show signs of being strung together and worn as a necklace or bracelet, as Bruce Bower reported in “Cache of eagle claws...
