SpaceX’s Crew Dragon capsule will depart the International Space Station and splash down in the Atlantic Ocean early tomorrow morning. It has been paired with the space station since Sunday, when it made its first docking under its own power after a successful Saturday launch atop a Falcon 9 rocket. This final phase of the Demo-1 mission will continue studying Crew Dragon’s new build. That includes testing an upgraded parachute system to land the craft more gently than its carg ...read more

The remains of nearly 140 children dating to the year 1450 have been unearthed along the northern coast of Peru. Archaeologists say the burial is the site of the largest known mass child sacrifice in the world. The children — as well as the remains of more than 200 young llamas — were found in a mass grave located on a cliff just a thousand feet from the Pacific Ocean in the small, present-day fishing community of La Libertad near Trujillo. Archaeologists say the children ...read more

In the elusive hunt for dark matter, some researchers are looking underground. The mysterious, unseen substance makes up more than 85 percent of the material in our universe. And since dark matter doesn’t interact much with normal matter (that's what makes it “dark”), scientists usually rely on extremely large detectors to maximize their chances of observing a signal. But the physical hunt for dark matter is relatively new, so these experiments have only been running for a few ...read more

“How about breasts?” The question came from a jock-y guy in one of my graduate school classes on human evolution. Far from offensive, the query was appropriate and astute. My classmates and I nodded approval, and the professor added it to a growing list on the board. We were brainstorming features that distinguish our species, Homo sapiens, from other primates. That list includes human peculiarities like big brains, upright walking, language, furless bodies ... and permanently ...read more

Scientists at Rockefeller University claim they’ve pinpointed a protein in the ear that acts as a sort of molecular gatekeeper, helping convert soundwaves into the electrical signals that our brains interpret as sound. The finding, though incremental, helps establish a more detailed understanding of how hearing works. Down the Inner-Ear Rabbit Hole But first, some basics. Deep inside the ear, through your ear canal and past your ear drum, lies the inner ear. Here, there’s a ...read more

Everyone loves Yellowstone, don't they? For a volcano that might not have erupted for 10,000 years, it gets a disproportion amount of media attention. Much of the hype is just because the media (news and entertainment alike) has made Yellowstone seem like something that is bound to erupt in our lifetimes and destroy all civilization. Yet today, there are really no signs today that the Yellowstone caldera is heading towards a new eruption anytime in the near future -- and that's geologic "nea ...read more

The new Apollo 11 documentary boasts that it is a “cinematic event fifty years in the making.” Which it is. It’s less a documentary and more a compilation of restored 16mm film and rarely-if-ever heard audio records from the first lunar landing mission, and it's absolutely incredible. (Heads up: this blog contains spoilers, but then again, most of us know what happened on Apollo 11, right? Right.)  The trailer, just in case you haven't seen it kicking around yet.

Our Um's and Uh's Aren't Totally Useless Ever catch yourself saying “uhhh” too many times? Many people vow to cut back on relying on such verbal crutches once they realize they’re using them, but they're not just filler. It seems they act as a cue of sorts for your conversational partners. Researchers from the Max Planck Institute for Psycholinguistics found that listeners actively track when a speaker says “uh” to help predict what kind of word might follow. The ...read more

Rare is the tech story whose main development is decidedly low-tech – but not impossible. Rather than a fancy atomic clock or rat cyborgs, for instance, this tech story deals with buckets of rocks and water. Well, solar panels too, but that’s not the cool new part. Today, at a meeting of the American Physical Society, Colgate University physicist Beth Parks described a new way to wring even more energy from a solar panel — a major development for people with no access to relia ...read more

Last December, a trio of astronomers set the record for the most distant object ever discovered in the solar system. Because the small world is located about three times farther from the sun than Pluto, the researchers dubbed it Farout. Now, not to be outdone (even by themselves), the same group of boundary pushers have announced the discovery of an even more far-flung object. And since the new find sits a couple billion miles farther out than Farout, the team has fittingly nicknamed it Farf ...read more
