In 1902, a Scottish novelist introduced a character who quickly became iconic. Peter Pan was a boy who could fly. He zipped between reality and an imaginary world, sometimes taking other children with him.Peter Pan was eternally a boy. He would never grow up, nor did he want to mature. Growing up would mean a loss of adventure and the burden of responsibility.Peter Pan Syndrome is now used to describe adults who struggle with accepting the responsibilities that come with adulthood. Although it†...read more
From coexisting with dinosaurs and surviving five mass extinctions, the Cuban manjuarĂ fish (Atractosteus tristoechus, or Cuban gar) today faces two threats that could finally break its historical resilience: the African Walking Catfish (Clarias gariepinus) and humanity.Scientists have struggled to track its population for decades, nearly losing sight of this remarkable fish despite its notable characteristics: a cylindrical, elongated body up to 60 inches long, covered in stone-like plates.The ...read more
Move over Triceratops, there’s a new horn-faced dinosaur in town. Researchers announced the fossil of an herbivore dinosaur with one of the largest, most ornate “frills” on its skull and two blade-like horns protruding from it, in the scientific journal PeerJ. Those features inspired its name, Lokiceratops rangiformis, which means “Loki’s horned face that looks like a caribou.” Lokiceratops appeared at least 12 million years earlier than its famous cousin Triceratops and at 22 feet l ...read more
Back in 1994, the Mexican physicist Miguel Alcubierre proposed a way for spacecraft to travel faster than the speed of light. Instead of accelerating the spacecraft across a region of spacetime, his idea was to contract spacetime ahead of it and expand spacetime behind it. In this scenario, the spacecraft sits in a flat bubble of spacetime that experiences little acceleration.The laws of physics that govern this behavior are Einstein’s field equations for general relativity. And they are fears ...read more
Imagine keeping a laser beam trained on a dime that’s 200 miles away. Now imagine doing that continuously for 24 hours, while riding a merry-go-round. Seem difficult? Well, that’s basically what the Hubble Space Telescope does.After months of technical issues, NASA announced June 4 that Hubble would shift into one-gyroscope mode. This essentially means that the telescope will have to rely on just one of the several gyroscopes – devices that measure an object’s orientation in space – it ...read more
