Frogs

Australian scientists have successfully revived and reactivated the genome of an extinct frog. The "Lazarus Project" team implanted cell nuclei from tissues collected in the 1970s and kept in a conventional deep freezer for 40 years into donor eggs from a distantly-related frog. Some of the eggs spontaneously began to divide and grow to early embryo stage with tests confirming the dividing cells contained genetic material from the extinct frog.  Read More

Confused by that headline? It's simple really – when drugs and medical devices are tested for contamination, a substance called Limulus amebocyte lysate (LAL) is used. LAL is made from the blood cells of horseshoe crabs, which are caught along the U.S. Atlantic coast, drained of 30 percent of their blood, then returned to the water. Although the majority of the crabs survive the process, it has been estimated that at least 30 percent do not. This, in turn, is affecting populations of the red knot, a bird that feeds on horseshoe crab eggs. Now, engineers from Princeton University have discovered that a substance from the skin of the African clawed frog could be used instead of the crab blood – with no harm done to the frog. No word on whether eye of newt or wing of bat would work, too.  Read More

The skin of certain frogs, including this foothill yellow-legged frog, contain secretions ...

While kissing a frog might not transform him into a handsome prince, his skin might one day save your life. Scientists in Abu Dhabi have discovered a method for using the natural substances found in frog skins to create a powerful new group of antibiotics with potential to fight against drug-resistant infections.  Read More

You’d think there’d be nothing new in the world to discover, but Mother Nature still has a few surprises up her sleeve. According to a new report from the World Wildlife Fund (WWF), scientists have discovered 353 new species in the eastern Himalayas over the past decade. They include a ‘flying frog’ that glides using long webbed feet, fossil evidence of a 100 million-year-old gecko, and the world’s shortest deer which, when fully grown, stands just 20 inches tall.  Read More
