University of Malaga scientists were studying the cardiovascular systems of Atlantic sawmill catsharks (catshark (Galeus atlanticus) when they found one with two heads. This is the first time that dicephaly (two-headedness) has been seen in an egg-laying shark. From National Geographic:
The causes of dicephaly aren't known, but the researchers—led by Valentín Sans-Coma of the University of Malaga—suspect that genetics are the most likely culprit (rather than some environmental factor, à la Blinky, the three-eyed fish, from The Simpsons)…
"We see two-headed sharks occasionally," says George Burgess, director of the Florida program for shark research at the Florida Museum of Natural History. "It's an anomaly, caused by a genetic misfire. There are lots of different kinds of genetic misfires, and most don't make it out of the womb."
"There's a reason you don't see a lot of sharks with two heads swimming around: they stand out like a sore thumb, so they get eaten," adds Burgess. "They would have trouble swimming and probably digesting food."
Researchers successfully revived ancient microbes, some more than 100 million years old, that were buried in the seafloor. During an expedition to the South Pacific Gyre, the scientists from the Japan Agency for Marine-Earth Science and Technology (JAMSTEC) and their colleagues drilled into the ocean sediment almost 6,000 meters below the surface. "Our main question […]
Around 2007, a child made a simple terrarium inside a glass bottle. Today, the bottle, unopened for more than a decade, is teeming with a lush ecosystem of algae, moss, fungi, and isopods. From Jartopia: I found this terrarium very fascinating as it's almost as if there are two separate worlds within the same glass […]
Every year, hundreds of thousands of horseshoe crabs, a threatened species, are "milked" for up to 30% of their blood that's used to test new medical drugs, including possible COVID-19 vaccines, for bacterial contamination. The animals are eventually released but, surprise, a large percentage of them die. Revive & Restore, the wildlife conservation organization most […]
Everybody's got a story. Unfortunately, not everybody has the tools to tell that story the right way. That's especially true for someone looking to produce their first screenplay. Just as with any type of writing, penning a script for the screen has a set of rules all its own. Understanding that structure, as well as […]
Even as the world takes tentative steps toward reopening against the ebbs and flows of COVID-19, movie theaters remain in a netherworld limbo. High-profile film releases continue shuffling as theater chains, studios and filmgoers grapple with the fact that an enclosed theater may not be a safe place to be for some time to come. […]
The year 2020 has basically kicked down that door and dragged us all into the Zoom age, whether we like it or not. And now that we're basically inviting our boss, co-workers and other business associates into our homes via video, we've unwittingly stumbled into all kinds of new potential for embarrassment. Like when you're […]
