1.8 Million Years Ago, Two Extinct Humans Had One Of The Gnarliest Deaths In History
When you’re tucked away in the safety of your home tonight, spare a thought for these two ancient human relatives whose lives in East Africa ended around 1.8 million years ago in a deeply undignified fashion: mauled to pieces by a crocodile and, somehow, chewed over by a leopard-like carnivore.

Evolution, Domestication, And A Lot Of Very Good Boys: How Wolves Became Dogs
Who’s a good boy? Oosagoodboyyy?! That’s right! Your dog is a good boy! But how he got that way is a puzzle that’s long plagued archaeologists and palaeontologists.

Why Do Orcas Have White Spots Near Their Eyes?
Orcas are easily recognized by their jet-black bodies punctuated with striking white markings, most notably the “eye patch” on their head, which makes them appear like an ominous masked supervillain. But these markings aren’t just eye-catching to humans – they’re an ingenious evolutionary tool. The black-and-white coloring of orcas is primarily a matter of camouflage. […]

The Real Reason The Tip Of Your Tape Measure Wiggles Like That
It’s the mainstay of every toolbox; a holiday stocking stuffer for a crafter of any kind; the precursor to one of those snappy bracelets that grade school kids love to thwap you with – we’re talking, of course, of the tape measure. Retractable, dependable, and always, for some reason, slightly wobbly at the end. But […]
The “Haunting” Last Message From NASA’s Opportunity Rover, Sent From Inside A Planet-Wide Storm
Thanks to NASA’s steadfast commitment to blasting robots into space, we now get regular images from another planet beamed back down to Earth.

Alzheimer’s-Linked Protein Levels “20 Times Higher” In Newborn Babies – What Does This Mean?
If you read any research about Alzheimer’s disease, two proteins are going to be your main characters. There’s amyloid-β, which builds up and forms plaques in the brain; and there’s tau, which aggregates into clumps called tangles. These tangles occur when the tau protein is altered by phosphorylation, and for many decades, the buildup of […]
Americans Were Asked If They Thought Civil War Was Coming. The Results Were Unexpected
Is civil war looming in the United States?

Dams Have Nudged Earth’s Poles By Over 1 Meter In The Past 200 Years
Over the past two centuries, humans have quietly nudged the very axis of our planet. As thousands of dams have been built across the world, Earth’s poles have tilted by over 1 meter (3 feet). The movement of Earth’s poles can be traced to two great waves of dam construction: first in North America and […]
This Sugar Could Be A Cure For Male Pattern Baldness – And It’s Been In Our Bodies All Along
Put down the rosemary oil and pause the red light therapy, research suggests the secret to curing male pattern baldness could lie in a sugar that occurs naturally in our bodies. In a mouse model of testosterone-driven hair loss, the sugar, called 2-deoxy-D-ribose, stimulated hair regrowth just as effectively as existing treatment minoxidil – the […]
“Cosmic Immigrants”: Daytime Star Seen In 1604 May Be An “Alien Type Ia Supernova”
An explosion seen in the cosmos in the early 1600s may actually be an “Alien Type Ia supernova”, according to a new paper. In October 1604, astronomer and mathematician Johannes Kepler spotted a new star in the sky and began tracking it. Over the course of several weeks, the star remained visible in the daytime […]
