• Rust under pressure could explain deep Earth anomalies

  08-06-2016 20:53
  
  Using laboratory techniques to mimic the conditions found deep inside the Earth, a team of Carnegie scientists led by Ho-Kwang "Dave" Mao has identified a form of iron oxide that they believe could explain seismic and geothermal signatures in the deep mantle. Their work is published in Nature.

• NASA’s Hubble pops in on a ‘superbubble’

  04-09-2026 19:09 via popsci.com
  
  At a spry 36-years-young, the NASA/ESA Hubble Space Telescope just keeps on going. The groundbreaking observatory recently took a new image of a sprawling nebula located in the Large Magellanic Cloud (LMC). The LMC is the largest of the small galaxies that orbit our home Milky Way galaxy, and it’s only 160,000 light-years away. Since it is relatively close by, astronomers can more easily observe star birth hot spots like LHA 120-N44 (or N44).N44 is located in the constellation Dorado. It i

• Bush dog puppies sound like birds

  04-09-2026 18:04 via popsci.com
  
  Five pups were recently born at England’s Chester Zoo, far from their homeland. But these bush dogs (Speothos venaticus) are on a mission—they’re part of a conservation breeding program protecting the future of their species. Bush dogs are medium-sized carnivores from Central and South America, known for their chirpy sounds. The IUCN Red List classifies them as Near Threatened. While that might indicate that they don’t need major conservation efforts as much the way

• Ancient American cheetahs were not exactly cheetah-like

  04-09-2026 17:00 via popsci.com
  
  The American cheetah (Miracinonyx trumani) stalked North America’s Pleistocene grasslands for nearly 2.5 million years, but new evidence suggests they likely didn’t resemble their present-day African namesake. After comparing M. trumani DNA to nine other feline species ranging from house cats to lions, it now appears that the ancient predator’s closest relative is an entirely different big cat. What’s more, M. trumani often roamed much farther north than researchers once

  Two unusually colored lobsters have been spared from the dinner plate and are living at the Gulf of Maine Research Institute (GMRI) in Portland, and will be educating students in the process. Ethel is a split-colored lobster, with a very autumnal orange and black hue, while Gertrude is a breathtaking blue.Shawn McEwen at Sea Salt Lobster Wholesale in nearby Saco, Maine contacted the team at the research center to see if they were interested in taking Ethel the two-toned lobster. “He t

  “Blue Jean Baby, L.A. Lady”… tiny earbuds in my head. As a writer in my second half-century, it’s expected, maybe even legally obligated, that I play some Elton John on every new audio device I test. But I don’t have to like it. Except today, I like it.

• I checked Best Buy’s 50%-off Labor Day sale against the competition. Here are the deals the hold up.

  03-09-2026 22:46 via popsci.com
  
  Shopping holidays are great for deals, but they can also be a trap. An item may say it’s “half-off” only to use a nonsense retail price as a starting point. Best Buy has a ton of deals as part of its Labor Day sale, but we’ve narrowed it down to the ones that will actually save you money. One thing to know about the math: Best Buy anchors most of these discounts to a “Comp. Value,” a comparable price from other stores, rather than to a price Best Buy itself ch

• Fossilized tissue reveals largest known T. rex died from broken rib

  03-09-2026 22:08 via popsci.com
  
  The largest Tyrannosaurus rex fossils ever discovered belong to a 66-million-year-old apex predator named Scotty. Like many T. rex skeletons, it’s difficult to determine if the specimen was male or female, but Scotty was an unequivocal bruiser. Standing 13-feet-tall at the hip and measuring upwards of 43-feet-long, the Late Cretaceous hunter weighed as much as 19,500 pounds.However, Scotty isn’t simply the biggest T. rex on record. One of its bones still has traces of preserved soft

• Ancient ring supposedly tied to Pontius Pilate may include a typo

  03-09-2026 20:01 via popsci.com
  
  The story of a 2,000-year-old ring potentially tied to one of the Christian Bible’s most impactful figures has yet another hypothesis. In a study recently published in the journal Palestine Exploration Quarterly, historian Catherine Bonesho argues that the letters on a ring often associated with the Roman governor Pontius Pilate refer to somebody named Pilate, and not necessarily the official who sentenced Jesus to death. The reason behind the mix-up? A common Roman translation error.The b

  Much like the earworm “The Song That Doesn’t End” from Shari Lewis’ Lamb Chops’ Play-Along, a new soft robot does not stop…curling up and jumping. A team of mechanical engineers from North Carolina State University say that they’ve created the bracelet-shaped bot that moves indefinitely when it’s exposed to infrared light. Called a Ring Leaper, the teardrop-shaped machine is made of a liquid crystal elastomer ring with a more rigid aluminum V

  An active childhood may train the growing body to make movement less demanding for life. A Penn State-led experiment found that birds raised while carrying extra weight became remarkably economical walkers. Once mature, they could transport the added load without using more energy than ordinary birds needed to walk unburdened. The findings offer rare direct [...]

  A new study finds that as people age, they remember fewer details from their past and have more difficulty switching between different types of memories. As people grow older, the broad story of a past experience may remain even as the sights, sounds, and emotions tied to a particular moment become harder to retrieve. Research [...]

  While we have months to wait for the first images from the freshly-launched Nancy Grace Roman Space Telescope, NASA’s other incredible observatories do not disappoint. The agency released a new collection of 16 galactic images taken with the Chandra X-ray Observatory and other telescopes. Galaxies are separated into three main categories—spirals, ellipticals, and irregulars. Spirals are like our own Milky Way and appear to spin around a central focus. Ellipticals are older galax

  A little less than 2,000 years ago, Mount Vesuvius became the antihero of the ancient world’s most well-known tragedy. The infamous explosion covered Pompeii and Herculaneum in volcanic debris, immortalizing the final moments of the ancient Roman cities and some of their unfortunate inhabitants in stunning detail. Now, however, visitors can witness the glory of Pompeii before it all came crashing down in 79 CE.
