Frilled shark (Chlamydoselachus anguineus) is a bizarre-looking fish and it has one of the most ancient lineages among all shark species. A headset is a great solution for improving both sound and speaking quality, especially if you do more phone Zooms than video. Dolly’s existence showed it was possible to change one cell’s gene expression by swapping its nucleus for another. The common name, frilled shark, derives f… “It’s almost like when you drive out of a parking lot exit and they have the spikes sticking out that say, ‘Do not back up.’ That’s kind of what happens when these things catch prey items.”. Scientists theorize that the extreme length has something to do with the shark’s cold deep sea habitat. Technically, though, Dolly was an exact genetic replica of only the sheep from which the cell was taken. Born on July 5, 1996, Dolly was cloned by Wilmut and Campbell's team at the Roslin Institute, a part of the University of Edinburgh, and Scottish biotechnology company PPL Therapeutics. Sometimes called a “living fossil” because it has changed so little since prehistoric times, the eel-like frilled shark—which is rarely seen by humans—has been in the news this week after a snake-like one was found off the coast of Portugal. The Saicco lamp even has a built-in charging port, so you’ll be able to hop off your Zoom and onto a conference call without ever needing to check your phone battery. The Food and Agriculture Organization of the United Nations notes that the frilled shark is “wide-ranging but spottily distributed”; you can see where the shark is found on the map above. Because she was cloned from a mammary gland cell, Dolly was named—dad joke alert—after buxom country music superstar Dolly Parton. The frilled shark’s mouth is just as terrifying as the maw of a great white: It’s lined with 25 rows of backward-facing, trident-shaped teeth—300 in all. A study of frilled sharks in Japan revealed that the animals breed year-round; litters typically consist of six pups, which emerge from eggs while still in the mother’s uterus and are then born live. Stem cell biologist Shinya Yamanaka told Scientific American that Dolly’s cloning motivated him to successfully develop stem cells from adult cells. The independent artists over at Redbubble have maps inspired by The Lord of the Rings, Game of Thrones, Zelda, and more, so no matter what you’re into, you’ll be able to bring a little pizzazz everywhere you (virtually) go. In fact, so widespread was the (mis)use of her name that her makers eventually trademarked it to stop the practice. Give your eyes a break with these blue light glasses from TIJN. Dolly had six offspring, and led a productive, sociable life with many human fans coming to visit her. The microphone has a custom-tuned microphone to provide high-quality sound, and it has both iOS and USB connectivity to make it easy to link to whatever device you’re using. So if you happen to see one of these anywhere, it’s better to look and not touch. In January 2007, a Japanese fisherman spotted a strange, eel-like creature with a mouth full of sharp teeth near the surface; he alerted the staff of the Awashima Marine Park in Shizuoka, who captured the animal and transferred it to a seawater pool, where they filmed it. This tripod is built to last, with flexible legs that are reinforced with a rubber coating, sturdy foam, and nonstick feet. But there are also a lot of headaches.
", Scientists, lawmakers, and the public quickly imagined a future shaped by unethical human cloning. Dolly, a woolly, bleating scientific miracle, looked much like other sheep, but with a remarkable genetic difference. For a Zoom backdrop that’s much cooler than a green screen, hang up a map from your favorite novel or video game for a look that’s both stylish and personal. Appliance manufacturer Zanussi used her likeness for a poster with her name and the provocative caption "The Misappliance of Science" (the poster was later withdrawn after scientists complained). On average, males range from 3.2 to 3.6 feet and females from 4.4 to 4.9 feet; the maximum these sharks can reach is 6.4 feet. Its scientific name is Chlamydoselachus anguineus, but this creature’s common name comes from its gills: Unlike all other sharks, which have separate gills, C. anguineus’ first pair of gills go all the way across its throat; each pair is lined at the edges with red “fringe.”, The sharks were first scientifically described by German ichthyologist Ludwig H.P. A “living fossil” is a species that hasn't changed …
International news outlets had already started swarming at the institute for access to Wilmut and Campbell's creation: Dolly the sheep, the world's first mammal successfully cloned from a single adult cell. The scientists cloned Dolly by inserting DNA from a single sheep mammary gland cell into an egg of another sheep, and then implanting it into a surrogate mother sheep. The team had kept the breakthrough under wraps for seven months while they waited for their paper to be published in the prestigious journal Nature. There are a lot of pros to Zoom meetings: You can wear pajama pants, you can mute yourself so no one hears your music in the background, and you can even turn your video off if you’re having a bad hair day. And that wasn't all: New York Times reporter Gina Kolata, one of the first journalists to give readers an in-depth look at Dolly, wrote Clone: The Road to Dolly, and the Path Ahead and contrasted the animal's creation with the archetypes in Frankenstein and The Island of Dr. Moreau. It typically resides in depths between 390 and 4200 feet, so people rarely see these sharks unless they venture to the surface, which isn’t unheard of (as you’ll see below). This cushion is ergonomically designed to reduce pressure on your tailbone and improve your posture with each use. In 1902, German embryologists Hans Spemann and Hilda Mangold, his student, successfully grew two salamanders from a single embryo split with a noose made up of a strand of hair. And as if its teeth weren’t freaky enough, the frilled shark has spines, called dermal denticles, lining its mouth.
(Parton didn’t mind the attribution.)
After they modify into specific types of cells, like neurons or blood cells, they're call specialized cells. Such an animal as that described is very likely to unsettle disbelief in what is popularly called the “sea serpent.” Though it could hardly on examination be taken for anything but a shark, its appearance in the forward portion of the body, particularly in the head, brings vividly to mind the triangular heads, deep-cleft mouths, and fierce looks of many of our most dreaded snakes. You can adjust each ring to 11 brightness levels, and the set even comes with a remote for your smartphone that can turn your camera on without awkwardly having to adjust it before a presentation. Döderlein, who taught at Tokyo University from 1879 to 1881 and brought two specimens captured in Tokyo Bay when he returned to Vienna.
In 2003, a veterinary examination showed that Dolly had a progressive lung disease, and she was put down. Since then, cloning experiments continued to become more sophisticated and nuanced. The Washington Post reported that "Dolly, depending on which commentator you read, is the biggest story of the year, the decade, even the century.
“We think it may have come close to the surface because it was sick, or else it was weakened because it was in shallow waters,” a park official said. American composer Steve Reich was so affected by Dolly's story that he featured it in Three Tales, a video-opera exploring the dangers of technology. Looking alert during meetings is always key, but it’s especially important during Zooms.
