Fossilized dinosaur footprints found on boulder
An Australian researcher discovered dozens of three-toed dinosaur footprints on a boulder in Callide Basin.
The next time you go shopping for a new purse, your choices could go beyond traditional materials such as leather, nylon, cotton and polyester to include … Tyrannosaurus rex skin?
Yes, the remnants of the prehistoric predator are being used to create synthetic T. rex leather, which can be turned into accessories including purses. That's the plan for a trio of companies – The Organoid Company, Lab-Grown Leather Ltd., and VML – working on "a high-quality alternative to traditional leather that's cruelty-free and eco-friendly," said the collaborators in an April 25 news release.
The goal of a "luxury fashion item," hitting later this year, would be the first example of leather developed from an extinct species, the companies said.
"With T-Rex leather we're harnessing the biology of the past to create the luxury materials of the future," said Bas Korsten, global chief creative officer, Innovation & CCO EMEA at VML, the agency behind the 2024 Super Bowl "Mayo Cat" campaign and 2023's Mammoth Meatball, made of lab-grown meat.

The team at The Organoid Company, a Netherlands-based biotech, will use fragments of T-Rex collagen protein recovered from fossils to recreate the prehistoric protein and engineer the new DNA into specialized cells for leather production. Another biotech company, the U.K.-based Lab-Grown Leather Ltd., will then use those specialized cells to produce skin, made with the T-Rex collagen protein, which is then tanned to form T-Rex leather.
"This project is a remarkable example of how we can harness cutting-edge genome and protein engineering to create entirely new materials," said The Organoid Company CEO Thomas Mitchell.
T. Rex leather could serve as a more environmentally friendly option to traditional leather and also eliminate "animal cruelty concerns," the companies said.
But some detractors consider the project misleading. University of Maryland vertebrate paleontologist Thomas Holtz, Jr. pointed out to Live Science, a science news site, how the lab-created skin won't be authentic because there's no actual T. rex skin or DNA to serve as a basis. "What this company is doing seems to be fantasy," he said.
Calling the announcement a "gimmick," Tom Ellis, professor of synthetic genome engineering at Imperial College London, told NBC News, 'I doubt that our knowledge of dinosaur evolution is good enough to be able to design a collagen gene specifically from T. rex."
But researchers have found collagen in an 80-million-year-old Tyrannosaurus rex fossil and that can be used as a template, they say.
The Organoid Company is creating a T-Rex protein by using fragments of the T-Rex collagen protein from fossils, the companies said in a statement to USA TODAY.
"An important distinction is that (the companies) are starting with the language of proteins, amino acids, rather than the DNA itself," according to the statement. "This encodes what the 3D structure looks like and from this they can then recreate or 'molecularly resurrect' the DNA which is put into special cell lines for leather production."
The result of this reconstruction of ancient protein sequences is T. Rex leather, which is structurally identical to T. rex skin. "A biomaterial inspired by prehistoric biology," Mitchell said.
Eventually, T. rex leather could be used beyond handbags and clutches to cover chairs and vehicle seats. "The production of T-Rex leather demonstrates VML's commitment to pioneering new grounds and shaping the future of our industry," Korsten said.

‘Land Of The Lost' Series Reboot In Works At Netflix From Legendary Television
EXCLUSIVE: Netflix is looking to remake another classic TV series. The streamer has closed a deal with Legendary Television for Land of the Lost, a reboot of Sid and Marty Krofft's 1974 sci-fi adventure show, Deadline has learned. Sid and Marty Krofft as well as Marty's daughter Deanna Krofft Pope, who is COO at their company, will produce the project, which is in very early stages, sources said. Search is underway for a writer. Reps for Netflix and Legendary TV declined comment. More from Deadline Spencer Milligan Dies: 'Land Of The Lost' Star Was 86 2025 Premiere Dates For New & Returning Series On Broadcast, Cable & Streaming Netflix Strikes "New Kind Of Partnership" To Carry TF1 Stations In France Land of the Lost centers on a father, Rick, and his two children who accidentally go through a portal and find themselves trapped in a world inhabited by dinosaurs, including a Tyrannosaurus rex they nickname Grumpy; primate-like people named Pakuni, one of whom, Cha-Ka, they befriend; and reptilian humanoids called Sleestak. Land of the Lost originated as a children's series which aired on NBC Saturday mornings for three seasons from 1974 to 1976, with CBS giving it a summer run in 1985 and 1987. In it, Rick was played by Spencer Milligan, with Wesley Eure and Kathy Coleman as his kids, Will and Holly, respectively. Stop-motion animation was used for some of the creatures. Despite its relatively short run, Land of the Lost achieved cult status, keeping the title relevant. That led to a 1991 series remake, which aired for two seasons on ABC, and a 2009 feature film starring Will Ferrell. Sid and Marty Krofft produced both. While it does not have the extensive library traditional TV studios do, Netflix has taken on a few classic series titles. The streamer is currently filming a new Little House On the Prairie and previously rebooted Lost In Space and One Day At a Time. Legendary Television's current slate includes Dune: Prophecy at HBO, Monarch: Legacy of Monsters at Apple TV+ and the animated Tomb Raider: The Legend of Lara Croft at Netflix as well as Tomb Raider and Pacific Rim live-action series and an adaptation of Girls and Their Horses with Nicole Kidman — all in development at Amazon.

This Australian moth uses the stars as a compass to travel hundreds of miles
NEW YORK -- An Australian moth follows the stars during its yearly migration, using the night sky as a guiding compass, according to a new study. When temperatures heat up, nocturnal Bogong moths fly about 620 miles (1,000 kilometers) to cool down in caves by the Australian Alps. They later return home to breed and die. Birds routinely navigate by starlight, but the moths are the first known invertebrates, or creatures without a backbone, to find their way across such long distances using the stars. Scientists have long wondered how the moths travel to a place they've never been. A previous study hinted that Earth's magnetic field might help steer them in the right direction, along with some kind of visual landmark as a guide. Since stars appear in predictable patterns each night, scientists suspected they might help lead the way. They placed moths in a flight simulator that mimicked the night sky above them and blocked out the Earth's magnetic field, noting where they flew. Then they scrambled the stars and saw how the moths reacted. When the stars were as they should be, the moths flapped in the right direction. But when the stars were in random places, the moths were disoriented. Their brain cells also got excited in response to specific orientations of the night sky. The findings were published Wednesday in the journal Nature. It 'was a very clean, impressive demonstration that the moths really are using a view of the night sky to guide their movements,' said Kenneth Lohmann, who studies animal navigation at the University of North Carolina at Chapel Hill and was not involved with the new research. Researchers don't know what features of the night sky the moths use to find their way. It could be a stripe of light from the Milky Way, a colorful nebula or something else entirely. Whatever it is, the insects seem to rely on that along with Earth's magnetic field to make their journey. Other animals harness the stars as a guide. Birds take celestial cues as they soar through the skies and dung beetles roll their remains short distances while using the Milky Way to stay on course. It's an impressive feat for Bogong moths whose brains are smaller than size of a grain of rice to rely on the night sky for their odyssey, said study author David Dreyer with Lund University in Sweden. 'It's remarkable that an animal with such a tiny brain can actually do this,' Dreyer said. ___ The Associated Press Health and Science Department receives support from the Howard Hughes Medical Institute's Science and Educational Media Group and the Robert Wood Johnson Foundation.
