The Big Hybrid Cat Breaks World Record for Being the Largest Feline In the Entire World

Once upon a time, 12,000 years ago, to be exact, tall, large tigers called the sabre-tooth tigers used to rule the world. They were so big that their very existence threatened humans daily.

Even though their breed has been extinct since the Pleistocene era, nowadays, scientific development allows experts to crossbreed between lions and tigers to create a new hybrid – the “liger.” The ligers are quite similar to the sabre-tooth tigers in height and weight.

A dumbbell-shaped nanoparticle powered just by the force and torque of light has become the world’s fastest-spinning object.

Scientists at Purdue University created the , which revolves at 300 billion revolutions per minute. Or, put another way, half a million times faster than a dentist’s drill.

In addition, the silica nanoparticle can serve as the world’s most sensitive detector, which researchers hope will be used to measure the friction created by .

Rare mounds of a crystalline mineral have emerged above the surface of Utah’s Great Salt Lake, where they’re expected to remain just a few months before disappearing again.

Scientists think these mounds may be similar to mineral structures on Mars that could preserve traces of microbes that may have lived in the planet’s saltwater lakes billions of years ago.

Cory Doctorow’s sunglasses are seemingly ordinary. But they are far from it when seen on security footage, where his face is transformed into a glowing white orb.

At his local credit union, bemused tellers spot the curious sight on nearby monitors and sometimes ask, “What’s going on with your head?” said Doctorow, chuckling.

The frames of his sunglasses, from Chicago-based eyewear line Reflectacles, are made of a material that reflects the infrared light found in surveillance cameras and represents a fringe movement of privacy advocates experimenting with clothes, ornate makeup and accessories as a defense against some surveillance technologies.

Researchers have developed a new way to use lasers to see around corners that beats the previous technique on resolution and scanning speed. The U.S. military is interested for obvious reasons, and NASA wants to use it to image caves. The technique might one day also let rescue workers peer into earthquake-damaged buildings and help self-driving cars navigate tricky intersections.

Researchers from Rice, Stanford, Princeton, and Southern Methodist University have developed a new way to use lasers to see around corners that beats the previous technique on resolution and scanning speed. The findings appear today in the journal Optica.

The U.S. military—which funded the work through DARPA grants—is interested for obvious reasons, and NASA wants to use it to image caves, perhaps doing so from orbit. The technique might one day also let rescue workers peer into earthquake-damaged buildings and help self-driving cars navigate tricky intersections.

One day. Right now it’s a science project, and any application is years away.
