With their thick white-gray fur and black rings, snow leopards are often hard to see against the rugged mountains that they call home. However, a team of photographers that included Mike Birkhead, has managed to capture amazing footage of this elusive cat walking away unscathed, after tumbling off a steep cliff....

Earlier this year in June, a villager in Garissa County, Kenya stumbled upon a rare sight — two white giraffes! Having never seen anything like it before, he immediately ran over to inform the rangers at the nearby Hirola Conservation Center, established to protect the critically endangered hirola antelope. Cameras in hand, the troopers rushed to the area to capture the first-ever video of the extremely rare specimens, who fortunately, appeared to be in no hurry to leave....

On September 6, the sun let its presence be felt by unleashing two massive solar flares. The first eruption, classified as an X2.2 flare, the strongest since 2008, occurred at 5:10 a.m. ET. Shortly after, at about 8:02 a.m ET, the star spewed out a bigger, and more spectacular, X9.3 flare — the most powerful on record since December 2006....

A team of astronomers, led by Alexander Boetticher of the University of Cambridge have stumbled upon what is being touted as our galaxy’s smallest known star. According to experts, EBLM J0555-57Ab, (57-Ab), which is slightly larger than Saturn, is the smallest possible size for a star. Boetticher says, “Had this star formed with only a slightly lower mass, the fusion reaction of hydrogen in its core could not be sustained, and the star would instead have transformed into a brown dwarf."...

Tony Stark, aka Ironman, constantly seen manipulating 3D holographic images and floating displays projected in mid-air from his phone or tablet. Unfortunately, the rest of us are not as fortunate because the current computer-generated holograms are too bulky to be integrated into our personal devices. However, if a team of researchers from Australia's RMIT University and the Beijing Institute of Technology (BIT) is right, we may all soon be able to mimic Ironman, at least, when it comes to playing with 3D holograms....

Tired of having to choose between dark, milk, or white chocolate? Then you may want to try the pink-hued ruby. Created by Swiss chocolatier Barry Callebaut, the all-natural confection is the first new variety to come to market since Nestlé introduced the world to white chocolate in 1930....

Fans of fidget spinners, 2017’s must-have toy, spend copious amounts of time spinning the three-pronged device with a flick of their finger. That’s because the addictive toys can rotate on their own, for only a few minutes at the most. However, if a Japanese company has its way, users will be able to relax and watch the gadget whirl for over 12 minutes with just one flick....

Most toys are fads that last a few years, or even months, before they get replaced by the next craze. However, the Slinky – the pre-compressed coil of wire, or plastic, which can “walk” on its own – has been entertaining children and nostalgic adults for over 70 years! It is therefore not surprising to hear that every August 30, fans across the U.S. celebrate this iconic toy with a National Slinky Day!...

Innovations like 3-D printing have enabled scientists to make significant progress in manufacturing various bioengineered organs and tissues. However, the one organ that has been hard to replicate is the human heart. That’s because current technology is unable to replicate the network of tiny blood vessels that transport oxygen inside a tissue as dense as the human heart muscle....
