More clues about where to search for a possible ninth planet lurking in the fringes of our solar system are emerging from the Kuiper belt, the icy debris field beyond Neptune. And new calculations suggest that the putative planet might be brighter — and a bit easier to find — than once thought. Evidence for […]

The cradle of agricultural civilization was culturally diverse. Two societies lived side-by-side 10,000 years ago in the rich Near Eastern valleys of the Fertile Crescent, where humans first learned to farm, a new study finds. Over time, one group expanded west, carrying agriculture into Europe. The other spread east, taking their traditions into South Asia, […]

Whiffs of ancient air trapped in rock salt for hundreds of millions of years are shaking up the history of oxygen and life on Earth. By carefully crushing rock salt, researchers have measured the chemical makeup of air pockets embedded inside the rock. This new technique reveals that oxygen made up 10.9 percent of Earth’s […]

Many homeowners go out of their way to make their yards friendly to birds. They plant vegetation or install feeders and birdhouses — and battle the squirrels that try to take advantage of that generosity. But what seems like a good deed for nature may be luring some birds to their deaths, a new study […]

CHICAGO — It’s a Higgs boson bonanza for particle physicists, who are capitalizing on the newest data from the Large Hadron Collider to delve more deeply into the particle’s properties. Scientists are keeping a keen eye out for any deviations from the standard model of particle physics, the overarching theory that describes elementary particles and […]

After decades of research revealing their sophisticated lives, Neandertals still can’t shake their reputation as knuckle-dragging cavemen. And it’s the Old Man of La Chapelle’s fault. The Old Man of La Chapelle was the first relatively complete Neandertal skeleton ever found. Three French abbés discovered the bones in 1908. Soon after, geologist and paleontologist Marcellin […]

Few of the expletives discussed in cognitive scientist Benjamin Bergen’s new book can be spelled out in this review. But Bergen argues, in a bluntly engaging way, that the largely secret science of swearing reveals much about who we are. Based on surveys of what people in several Western nations regard as unacceptable, the author […]

A spacecraft destined to bring samples of an asteroid back to Earth is scheduled to launch tonight. NASA’s OSIRIS-REx mission will launch September 8 at 7:05 p.m. EDT atop an Atlas V rocket from Cape Canaveral Air Force station in Florida. The probe will head for 101955 Bennu, a roughly 500-meter-wide asteroid whose 1.2-year orbit […]

A salty ocean more than 100 kilometers deep might lurk beneath Pluto’s icy heart, a new study suggests. The buried reservoir could have helped tip the dwarf planet over at some point in its past, bringing the heart-shaped region in line with gravitational forces from Charon, Pluto’s largest moon. A subsurface ocean isn’t a new […]

Man’s best friend can sometimes be wildlife’s worst enemy. Free-roaming dogs, both feral and owned animals that run loose, spread rabies and other diseases, kill wild animals and have caused extinctions. They’re even to blame for thousands of human deaths every year. And yet dogs get little of the hatred aimed at feral cats — […]
