Watch Corals Move in Timelapse Video

Corals and other "slow life" do move, though we often think of them as very nearly static. In order to see their movement, you need to change your perspective -- slow way down, photograph in timelapse, and then carefully assemble the result so that humans can understand what that motion looks like from the perspective of such a slow creature. Photographer Daniel Stoupin has done just that with his short film Slow Life, three and a half minutes of timelapse that took nine months to create. Behold, and definitely go fullscreen:

What's most interesting to me is how much these creatures look like photographs of galaxies. "As above, so below," as they say.

Stoupin wrote a lengthy article about this film that's well worth a read. Here's part:

The most important living organisms that play the key functions in the biosphere might not seem exciting when it comes to motion. Plants, fungi, sponges, corals, plankton, and microorganisms make life on Earth possible and do all the hard biochemical job. Similarly to all living things, they are dynamic, mobile, and fundamentally have the same motion properties as us. They grow, reproduce, spread, move towards source of energy, and away from unfavorable conditions. However, their speeds happen to be out of sync with our narrow perception. Our brains are wired to comprehend and follow fast and dynamic events better, especially those very few that happen at speeds comparable to ours. In a world of blazingly fast predators and escaping prey events where it takes minutes, hours, or days to notice any changes are harder to grasp

Criminal Gangs Are Smuggling Illegal Rhino Horns as Jewelry

Valuable jewelry isn't always made from precious metals or gems. Wildlife smugglers in Africa are increasingly evading the law by disguising illegally harvested rhinoceros horns as wearable baubles and trinkets, according to a new study conducted by wildlife trade monitoring network TRAFFIC.

As BBC News reports, TRAFFIC analyzed 456 wildlife seizure records—recorded between 2010 and June 2017—to trace illegal rhino horn trade routes and identify smuggling methods. In a report, the organization noted that criminals have disguised rhino horns in the past using all kinds of creative methods, including covering the parts with aluminum foil, coating them in wax, or smearing them with toothpaste or shampoo to mask the scent of decay. But as recent seizures in South Africa suggest, Chinese trafficking networks within the nation are now concealing the coveted product by shaping horns into beads, disks, bangles, necklaces, and other objects, like bowls and cups. The protrusions are also ground into powder and stored in bags along with horn bits and shavings.

"It's very worrying," Julian Rademeyer, a project leader with TRAFFIC, told BBC News. "Because if someone's walking through the airport wearing a necklace made of rhino horn, who is going to stop them? Police are looking for a piece of horn and whole horns."

Rhino horn is a hot commodity in Asia. The keratin parts have traditionally been ground up and used to make medicines for illnesses like rheumatism or cancer, although there's no scientific evidence that these treatments work. And in recent years, horn objects have become status symbols among wealthy men in countries like Vietnam.

"A large number of people prefer the powder, but there are those who use it for lucky charms,” Melville Saayman, a professor at South Africa's North-West University who studies the rhino horn trade, told ABC News. “So they would like a piece of the horn."

According to TRAFFIC, at least 1249 rhino horns—together weighing more than five tons—were seized globally between 2010 and June 2017. The majority of these rhino horn shipments originated in southern Africa, with the greatest demand coming from Vietnam and China. The product is mostly smuggled by air, but routes change and shift depending on border controls and law enforcement resources.

Conservationists warn that this booming illegal trade has led to a precipitous decline in Africa's rhinoceros population: At least 7100 of the nation's rhinos have been killed over the past decade, according to one estimate, and only around 25,000 remain today. Meanwhile, Save the Rhino International, a UK-based conservation charity, told BBC News that if current poaching trends continue, rhinos could go extinct in the wild within the next 10 years.

Big Questions
Do Cats Fart?

Certain philosophical questions can invade even the most disciplined of minds. Do aliens exist? Can a soul ever be measured? Do cats fart?

While the latter may not have weighed heavily on some of history’s great brains, it’s certainly no less deserving of an answer. And in contrast to existential queries, there’s a pretty definitive response: Yes, they do. We just don’t really hear it.

According to veterinarians who have realized their job sometimes involves answering inane questions about animals passing gas, cats have all the biological hardware necessary for a fart: a gastrointestinal system and an anus. When excess air builds up as a result of gulping breaths or gut bacteria, a pungent cloud will be released from their rear ends. Smell a kitten’s butt sometime and you’ll walk away convinced that cats fart.

The discretion, or lack of audible farts, is probably due to the fact that cats don’t gulp their food like dogs do, leading to less air accumulating in their digestive tract.

So, yes, cats do fart. But they do it with the same grace and stealth they use to approach everything else. Think about that the next time you blame the dog.
