Coral reefs are some of the most diverse and vital ecosystems on Earth. The colorful underwater colonies of coral polyps, held together by calcium carbonate, provide homes for many marine plants and animals and help keep the ocean's nitrogen levels balanced. But while scientists are aware of where the world’s reef systems are located, there is no complete record of all the different types of coral that live there. Now, NASA researchers are hoping to entice nature lovers, both experts and amateurs, to help them create a comprehensive database of these all-important ecosystems by playing a fun, interactive video game!...

The eyes of Leonardo da Vinci’s iconic Mona Lisa have long been thought to follow viewers around the gallery of the Louvre Museum in Paris where it is exhibited, as well as those looking at photographs and reproductions of the famous painting. Now, researchers from Germany's Bielefeld University assert that while “The Mona Lisa Effect,” – the impression that the eyes of the subject in a portrait are following the viewer – is real, it is not true for its namesake painting....

Expected to be at their peak on Thursday and Friday night (Dec. 13-14, 2018), the dependable meteors rank high in both quantity and quality. Nicknamed the “900-pound gorilla of meteor showers” by NASA, they outweigh other dust streams by factors of between 5 to 500!...

Dolphins have been known to demonstrate many human-like behavioral traits. These include forming complex relationships to accomplish common goals, teaching one another survival skills, and even “babysitting” each other's kids. Now, some researchers at the Dolphin Plus Marine Mammal Responder in Key Largo, Florida have discovered another thing the intelligent mammals share with humans – a love for television!...

Most dog owners are convinced that their four-legged friends know exactly what they mean when they use certain words like sit, stay, or treat. However, researchers have always wondered whether canines really understand human speech or if they rely on other clues to deduce the meaning. For example, does the word “fetch” conjure up an image of a stick or ball in the dog’s mind, or does the pooch retrieve the object based on cues such as the owner’s tone or gesture? A new study by scientists at Atlanta’s Emory University seems to indicate that “man’s best friend” is not faking it – he/she does indeed know what the owner is saying....

The residents of Ashwaubenon, Wisconsin are no strangers to wild turkeys. However, “Smoke,” a lone bird who has been a fixture in the town since spring this year, is like none other they have encountered before. The renegade turkey pursues moving vehicles, “controls” traffic flow by parking himself in the middle of the road, and even chases after children as they descend from school buses. He is also known to boldly approach residents and gobble at them, as though sharing some pertinent information....

US gymnast Simone Biles, who has dominated the sport since the 2013 World Championships, is often described as “the greatest gymnast of all time” and “superhuman.” The 21-year-old phenom proved herself worthy of both labels at the recently held World Championships in Doha, Qatar when she won a medal in every discipline, including four golds, while battling a painful kidney stone....
