The dumbo octopus (Grimpoteuthis) is a bit different than most cephalopods. This genus of pelagic umbrella octopus live in the cold, abyssal depths ranging from 3,000 to 23,000 feet.   https://t.co/oi2YAmkLNP

Could this young girl be forming crystals in her eyes? 👁️

The explanation could be a rare genetic disorder called Cystinosis, a rare build up of cystine, an animo acid. But the truth could mean something more serious.

The Three Gorges Dam is the largest in the world, but it had a massive impact on its surrounding environment.

If we were to build something as incredible as the Hoover Dam today, could we make it completely green?

Happy #InternationalSlothDay!  🦥  To celebrate we're sharing this illustration of the extinct giant ground sloth, Megalonyx. 

These large clawed, heavy built animals roamed North America until they became extinct during the Quaternary extinction event around 11,000 years ago. https://t.co/N6Y1R0hSVJ

How is it possible that the incredible Hoover Dam was built during the great depression?

If we truly do exist in a multiverse - or one of multiple dimensions of space - we might be able to understand more closely how our Universe will end, and if we’re the only one hospitable for life.

Plenty of cases to solve before then.

Dark energy is the unknown force that is causing the Universe to expand at an accelerating rate.

Scientists believe that the Universe will experience one of two fates: the “Big Crunch,” or the “Big Freeze,” a neck-to-neck battle between entropy and gravity. 🪢

#KillersOfTheCosmos https://t.co/NlgzAaqGQX

Gravity could stop the Universe’s never ending expansion. 

If the Universe shrank, all of the heat and energy would crash down in a wave of ever-increasing intensity, powerful enough to tear planets apart, destroy stars, and wipe out all life.

Death by entropy would be dark and cold - theorized by scientists as the “Big Freeze.” 🧊

Beginning with the burnout of stars, the Universe would be left as a sea of subatomic particles a fraction above zero degrees.

Entropy is the law that states order will ultimately end in disorder. This matters on every scale - from tiny chemical reactions, to life, planets, and entire galaxies. 🧬
