- Conservationists are trying to save this endangered bird. But their efforts may be producing too many malesConservation programs aim to protect the critically endangered maleo bird in Indonesia by moving eggs to hatcheries. While this interventio...
- 150-year-old human might already be among us, claims Harvard scientist. His experiment may have unlocked how long we can really liveWhat if humans could eventually live for 150 years, not through a simple extension of existing treatments but by actually turning back some...
- Why bringing back the woolly mammoth isn’t a simple cloning job — scientists are solving a massive genetic engineering puzzleColossal Biosciences is working to introduce woolly mammoth traits into Asian elephants through genetic modifications. Researchers are usin...
- Your brain may be one organ today, but scientists have uncovered a hidden split that may date back more than 500 million yearsNew research suggests the human brain develops from two distinct cell populations. These groups follow separate paths from early embryonic ...
- In 1983, three pregnant guppies flew on Cosmos 1514 for five days; one later gave birth to 25 healthy fry and produced six more healthy broods after returning to EarthIn 1983, three expectant guppies journeyed aboard the Cosmos 1514 biosatellite as part of a Soviet experiment exploring the effects of micr...
- In 1979, Cosmos 1129 flew five female and two male rats for 18.5 days and allowed them to mate; no normal pregnancies resulted in flight, while a later ground study produced healthy littersCosmos 1129, a Soviet biosatellite, conducted groundbreaking research on rat reproduction in space. Through ground simulations that mimicke...
- In 1994, NASA flew four Japanese red-bellied newts on STS-65 for nearly 15 days; two adults died, but 32 newt eggs hatchedSpace Shuttle Columbia's 1994 mission studied animal reproduction in zero gravity. Four red-bellied newts and medaka fish were part of biol...
- In 2003, researchers found freshwater snails had mated in space; their gravity-sensing statoconia were 50% larger by volume than matched ground controlsExperiments conducted aboard the Space Shuttle demonstrated that pond snails bred in microgravity possessed larger gravity-sensing structur...
- In 1966, Marlon Brando bought a remote Pacific atoll after filming ‘Mutiny on the Bounty’; today, its protected beaches are a major nesting site where 15,614 green turtle hatchlings were recorded in one seasonMarlon Brando bought a Polynesian atoll named Tetiaroa after discovering it while filming Mutiny on the Bounty. More than five decades late...
- In 1989, the space shuttle Discovery carried 32 fertilized chicken eggs for 5 days; all 16 early embryos died, while 8 older embryos later hatched without anatomical malformationsIn 1989, the space shuttle Discovery transported thirty-two fertilized chicken eggs into microgravity. Although younger embryos did not end...
- Dolly the sheep was named after Dolly Parton, but do you know the reason? Here’s how the world’s first adult-cell clone got its name from the country music legendDolly the sheep made headlines in 1996 when she became the first mammal to be cloned from an adult somatic cell using a technique called so...
- In Argentina, one fossil bone from a 236-million-year-old cynodont contained a rare clue about birth. Researchers found its newborn size resembled mammals, suggesting live birth evolved 95 million years earlier than thoughtNew fossil evidence challenges the long-held belief that ancient cynodonts laid eggs. A recent study found compelling proof that Chiniquodo...
- North America saved its bison from extinction. Now scientists face a new threatBison numbers have recovered after near extinction, but genetic diversity is now a concern. Fragmented herds lack natural gene exchange, po...
- In 2017, hundreds of fossil eggs in China revealed that Pterosaurs or ancient flying reptiles may have raised their youngIn a remarkable discovery, paleontologists in China unearthed hundreds of fossilized pterosaur eggs and bones, dating back 120 million year...
