Scientists Create 3D-Bioprinted Hair Follicles In Lab-Grown Skin
New research has seen scientists use 3D bioprinting to sprout hair follicle-like structures into lab-grown human skin tissue. Researchers at the Rensselaer Polytechnic Institute in the US start the process by “growing “ samples of skin and follicle cells in a lab, after which they’re mixed with special proteins and other materials to create a […]

How Many Volcanoes Are Actively Erupting Today? More Than You May Think
Hundreds upon hundreds of active volcanoes are scattered across planet Earth, but only a small number are currently in the grips of a violent eruptive episode. While it’s difficult to predict when a volcano might blow, geologists are constantly keeping tabs on those that are already neck-deep in an eruption. There are approximately 1,350 potentially […]
People Are Weirdly “Shaken” By The Ingredients Of McDonald’s Sweet & Sour Dip

While some suggested pineapple might be the elusive star of the smooth sauce, others have been left “shaken” by the discovery that it is in fact apricot. […]
How The Faces Of 3 Medieval Scots From The “Cradle Of Christianity” Were Revealed
In recent years, facial reconstruction technology has allowed us to come face-to-face with our ancient ancestors in a way that had never been possible before. From a 50,000-year-old geriatric Neanderthal, to a medieval man with achondroplastic dwarfism, and the ever-enigmatic “hobbit” hominid Homo floresiensis, our forebears faces can now be revealed in stark relief. In […]
Endangered Green Sea Turtles Being Feminized By Hormone Mimicking Pollutants
Research on populations of green sea turtles suggests that specific pollutants that accumulate in female turtles could be passed onto their young and may cause them to become feminized. This situation may compound issues for a species that already has fewer male hatchlings. “Green sea turtles are listed as endangered on the IUCN Red […]
120-Million-Year-Old Fossil Footprints Become Australia’s Oldest Bird Tracks On Record
The astonishing discovery of 27 fossil bird footprints dating back 120 to 128 million years is changing the way we view avian evolution and migration. Found in the Wonthaggi Formation south of Melbourne, they were laid down in the Early Cretaceous and created by birds stepping across soft sand or mud. The footprints are so […]
Texas Might Be Home To Woolly Mammoths Sooner Than You Think
Modern day Texas is home to deer, rattlesnakes, and bobcats, to name a few animals, and – according to news from a de-extinction company – soon, it might also have mammoths. The company behind the ambitious target is Colossal Biosciences, and it’s their goal to have living, breathing mammoths at their Texas-based facility by 2028. […]
Plants “Cry Out” When They Need Water, We Just Can’t Hear Them
If you’ve ever spent time around babies, you’ll know that the main way they communicate their needs and feelings is through crying.

Are Our Observed Black Holes Concealing Wormholes?
The known universe is full of exciting things like black holes, hypernovas, and merging neutron stars. All of those, however, look tame compared to items physicists think might exist but have yet to find. Perhaps chief among these are wormholes, which theoretically join parts of space and time, allowing those who enter them a shortcut […]
