Ruby the Burmese roofed turtle (Batagur trivittata) might not be fighting crime like the Teenage Mutant Ninja Turtles, but this very real turtle is beginning to make her own mark on culture. The critically endangered reptile living at a top secret turtle sanctuary in New Jersey is inspiring professional dance companies to choreograph conservation into their work.  Burmese roofed turtles are among the most rare turtle species on Earth, and almost went extinct in the early 2000s.

Govee makes some of our favorite solutions out there, and we just spotted its smart RGBIC Christmas tree lights going for less at Amazon.

It’s the lowest we have seen them drop to in a long while. It was also originally a Black Friday discount, which managed to survive the main event. You’ll enjoy…

Another CES is nearly upon us, another year where we’ll see new gadgets aplenty from giant companies and tiny ones you’ve never heard of. And the not-so-secret secret of CES is that many of these things never make it to market — but usually it isn’t things companies like Samsung show off. But here we are, nearly six years since Samsung first showed off its Ballie personal robot and it is nowhere to be found.For those who may not recall, Ballie is an adorable circular robot that can putter around your house and project things onto the floor and wall.…

In 1903, residents of the small town of Dexter, Kansas, gathered to celebrate a newly drilled natural gas well.Crowds flocked to the well for the lighting of the escaping gas, which officials had said would produce “a great pillar of flame.” But when they rolled a burning bale of hay onto the well, nothing happened.An analysis in 1905 revealed that most of the gas was nonflammable nitrogen, just 15% was methane — and a little less than 2% was a colorless, odorless, elusive element that scientists had discovered only a few decades earlier. This marked the first discovery of helium…

And though it only has a one-sided kickstand as opposed to a scooter-style underframe stand, the bike’s aforementioned short wheelbase means it never felt unstable when I hopped off and kicked the stand down. It also comes with a nifty little setting that’ll give you a little extra boost while walking the bike. Again, if you’re pushing a ~50-pound bike uphill, you might need some extra oomph.Other than the ultra-cool, deep-red-logo-on-flat-metallic paint job, the real showstopper on the Mustang is its control system, which features a stunning, full-color LCD display that shows in real time your speed, remaining battery, pedal…

Upgrading your work or everyday laptop doesn’t have to break the bank; especially if you know where to look for one. Black Friday and Cyber Monday are over, but there’s still one last chance left to save big on a premium laptop, and bag some freebies with your purchase while you’re at it. The 17.3-inch HP touchscreen laptop, which usually sits well over $2,600, is currently going for just $770 at Amazon, after a whopping 70% off its usual price. It’s the lowest we have seen it drop to in a month, and the retailer is also throwing in a…

In his book “One Hand Clapping: Unraveling the Mystery of the Human Mind” (Prometheus/Swift Press, 2025), New York University neuroscientist Nikolay Kukushkin traces the evolution of human consciousness. He starts the story with the emergence of the first DNA on Earth and then highlights key evolutionary landmarks that paved the way to us — namely, modern-day humans. In the following excerpt, Kukushkin describes the “social brain hypothesis,” which posits that human intelligence arose, in part, to help us keep track of our increasingly complex social groups.What made us humanIn the past, many explanations of human uniqueness focused on what gave…
