(Credit: chaiyawat chaidet/Shutterstock) Transfusing blood from young mice into those with Alzheimer’s doesn’t appear to treat the disease. It’s an out-there concept that seems more of a kind with cryogenetics and organ xenotransplants but the promise of rejuvenation by blood infusion actually has some scientific legs to stand on. Shoulder to Lean On That the blood of the youthful might help the elderly was first proposed over 150 years ago when studies of mice whose cir ...read more

(Credit: Shutterstock) When paleontologists pull woolly mammoth fossils from mud pits, sinkholes, mudflows and other ancient booby traps, odds are it was a male that fell victim to the hazard. This macabre gender bias, researchers say in a new study, serves as a window into the behavioral patterns of these hirsute beasts that died out roughly 10,000 years ago. It turns out, as one might expect, woolly mammoth society may not have been so different from the pachyderm families that roam earth to ...read more

The First Americans may have followed a “kelp highway” of marine resources via a coastal route from Siberia to the New World. Nutrient-rich kelp beds such as these, near Crook Point on the Oregon coast, attract salmon and other sea life that would have sustained the early explorers. (Credit Roy W. Lowe/U.S. Fish & Wildlife Service) The average person’s idea of how — and when — the first people arrived in the Americas needs a serious revision, say researche ...read more

We found you Tapanuli orangutan! (Credit: Maxime Aliaga) A newly discovered species of orangutan is already teetering on the edge of extinction. The Tapanuli orangutans (Pongo tapanuliensis) have been identified as the most endangered great ape species in the world, consisting of less than 800 individuals. That population size is strikingly different from the two other known species of orangutans. There are an estimated 14,000 Sumatran orangutans (Pongo abelii) and 100,000 Bornean ora ...read more

(Credit: Don Mammoser/Shutterstock) A large chamber, never-before observed, has been discovered in the Great Pyramid at Giza. The previously unknown space was announced Thursday by an international team of researchers who used cosmic ray detectors to discern the presence of what they call a “big void” inside the pyramid’s structure as part of the Scan Pyramids project. The void lies just above the Grand Gallery passageway that leads to the King’s chamber within the mass ...read more

Having recently left an academic post, I’ve been thinking about what will happen to the data that I collected during my previous role that remains unpublished. Will it, like so much data, end up stuck in the limbo of the proverbial ‘file drawer’? The ‘file drawer problem’ is generally understood to mean “the bias introduced into the scientific literature by selective publication – chiefly by a tendency to publish positive results but not to publish nega ...read more

A proposed dinosaur family tree rewrite may sound like a crazy idea, but remember, not that long ago scientists thought Iguanodon looked like this (hint: we know better now). (Credit Samuel Griswold Goodrich/Illustrated Natural History of the Animal Kingdom, 1859) Earlier this year, a trio of paleontologists led the charge to rewrite the most fundamental thing we believe about dinosaurs. Their call to action generated controversy and, more importantly, serious academic discussion. Now, a b ...read more

(Credit: Shutterstock) For years, experts thought Alzheimer’s, a progressive neurodegenerative disease, originated in the brain. After all, it’s the organ that takes the beating: Proteins build up in the brain, forming plaques or tangles that can damage cell function. And depending on which hypothesis you’re reading up on, the critical damage that kick-starts symptoms comes from either beta-amyloid proteins, the traditional suspects, or tau proteins, a relatively new but incr ...read more
