Three Earth-like planetsSerge Bloch for Reader's DigestAstronomers found not just one but seven planets outside our solar system that circle a tiny star called TRAPPIST-1, about 40 light-years away. Three are in what NASA calls the habitable zone, which could be right for water to exist and possibly for extraterrestrial life. Think you know all there is to know about earth now? Take this quiz to find out.
Shrimp so loud, they were named after a rock bandJ.W.Alker/imageBROKER/REX/ShutterstockOn the Pacific coast of Panama, scientists discovered a new type of pistol shrimp that uses its large pink claw to create a noise so loud it can stun—or even kill—small fish. In fact, the boom created by the animal’s snapping claw can reach 210 decibels. For comparison, a loud concert is about 110 to 140 decibels. (Humans can lose their hearing from loud concerts and even loud cities.) The team members dubbed it Synalpheus pinkfloydi, inspired by their love of Pink Floyd.
olivialazer/ShutterstockAs we age, senescent, or damaged, cells build up in our tissues, possibly promoting age-related diseases. Scientists from the Netherlands developed a molecule that purges those cells. When tried on elderly mice, their fur regrew, their kidney function improved, and they could run twice as far as untreated mice. One scientist called it a landmark advance in the field of aging. Since we're not mice, try eating these foods to add years to your life.
via renovacareinc.comIf a burn victim's wounds are severe, home remedies for burns aren't nearly enough. So biomedical scientists have created a device that sprays stem cells onto wounds, helping them grow a new, healthy layer of skin in as few as four days. Biotech firm RenovaCare recently obtained a patent for the SkinGun and has used it to successfully treat dozens of burn patients in trials. While the device still needs FDA approval, it’s a game changer that could help eliminate the painful and scarring process of skin grafting.
Auscape/UIG/ShutterstockA bite from an Australian funnel-web spider could kill you in 15 minutes if not treated promptly. But scientists discovered that a peptide found in the venom of one species may protect brain cells from being destroyed by a stroke, even when given eight hours after the event. If the treatment fares well in human trials, it may become the first drug that can protect against stroke-induced brain damage. These are signs of a stroke you might be ignoring.
via imdb.comScientists in Toronto identified a new species of dinosaur and named it Zuul, after the doglike monster in the 1984 film Ghostbusters. Like its namesake, the dinosaur had horns behind its eyes, spikes on its face, and a barbed, sledgehammer-like tail. The dinosaur’s fossilized skeleton, unearthed in Montana, is one of the most complete ankylosaurs—armored, lizard-like dinosaurs—ever found, with skull and tail club intact.
LARRY-W.-SMITH/EPA/ShutterstockScientists discovered that the slime covering the skin of a frog from southern India contains antimicrobial peptides that destroy bacteria and viruses—including key strains of the human flu—while protecting normal cells. So far, the therapy has been used only in the lab. These are 6 clear signs you have the flu.
Marko-Köni/imageBROKER/REX/ShutterstockScientists found a new antimicrobial compound in the blood of Komodo dragons, the world’s largest lizards. In the lab, the substance healed infected wounds on mice faster than existing options, potentially giving doctors a new tool to fight antibiotic-resistant infections. Not sure if your cut in infected? Look for these tell-tale signs.
