Are zebras white with black stripes or black with white stripes? | Live Science

Zebras are iconic for their distinctive coats, but have you ever wondered whether zebras are white with black stripes or black with white stripes?

The stunning black-and-white coloration of the zebra’s hide stands out in stark contrast with the dry, brown-and-green, treeless grasslands and savannah woodlands of their home territories of East and southern Africa, according to the African Wildlife Foundation.

These stripes are unique to each individual. There are three zebra species living today — the plains zebra (Equus quagga), the mountain zebra (E. zebra) and the Grevy’s zebra (E. grevyi) — and each of those species has a different striping pattern, too. For some, the darker portions of their hide are black, whereas others have browner coloring, and some have stripes only on their bodies but not on their legs. An extinct subspecies of the plains zebra called a quagga (E. quagga quagga) had minimal striping on its head, mane and neck, according to The Quagga Project.

Why Do I Get Sore Days After I’ve Worked Out? | Live Science

Why Are There 9 Supreme Court Justices? | Live Science

Supreme Court justice Anthony Kenneday said he’s retiring at the end of July, meaning the court will hold just eight justices until a new nominee gets confirmed by the U.S. Senate.

Eight justices also manned the court between February 2016 when Justice Antonin Scalia died and Neil Gorsuch was confirmed on April 7, 2017.

However, it turns out, the original U.S. Constitution did not set the number of justices on the Supreme Court. Therefore, it was up to Congress to decide, and in 1801, it set the number at five. But things didn’t stay that way for long.

The High Tech Gadgets You’ll Actually Want to Put Near Your Face | Elle

Pros have long harnessed the power of LEDs (light-emitting diodes) for stealth skin enhancing with zero downtime.

Experts say algae is the food of the future. Here’s why. | CNN Money

I have commitment issues — with my diet.

Name the diet, and I’ve tried it. I’m currently a pescatarian with fish as my main protein source. But I’ve been a carnivore, vegetarian and vegan, too.

Oh, and I dabble in “menu of the future” items such as algae and bugs.

In the last month, I’ve had algae smoothies, algae protein bars and algae chips. It’s not because I’m a particularly adventurous eater or that I love the taste. I actually loathe the mossy flavor of algae.

I eat it because I’m a worry wart when it comes to our environment. We’ve gotten ourselves into some trouble. Our dining habits are a big part of the problem.
