Farmer Sets Out to Grow a Pretty Plant—Creates World’s Hottest Pepper Instead

Some peppers are perfect for adding a subtle, spicy kick to your favorite dish. Others are so hot they’re eaten as a test of strength. Then there are hot peppers that present a health hazard to anyone who attempts to consume one. The Dragon’s Breath chili belongs in latter group. As The Telegraph reports, the puny fruit packs a heart-pounding 2.48 million Scoville heat units—that's 1.5 times hotter than the current hottest pepper record-holder, the Carolina Reaper.

Competitive gardener Mike Smith didn’t intend to grow a pepper with taste bud-incinerating spice levels. His goal was to cultivate a chili plant on his Welsh farm that was good-looking enough to win Plant of the Year at the Chelsea Flower Show. With help from Nottingham Trent University scientists, who were interested in the chili’s medicinal potential as an anesthetic, he produced a pepper that’s attracting attention for reasons other than its beauty.

The chili’s heat content is so high that scientists warn that any daredevil who eats one might go into anaphylactic shock and die from asphyxiation. This led many outlets to describe the Dragon’s Breath chili as a pepper so hot it can kill you, but Gizmodo explains that eating a lethal dose of the stuff would be harder than headlines make it out to be. According to the article, you’d need to eat over half a pound, or 25 to 30 Dragon’s Breath chilis, to die from capsaicin poisoning. Based on Smith’s description of the taste, just getting past the first pepper sounds like a challenge.

“I’ve tried it on the tip of my tongue and it just burned and burned," he told The Telegraph. "I spat it out in about 10 seconds.”

Smith’s creation failed to win Plant of the Year at the Chelsea Flower Show, but if the scientists’ Scoville Heat Unit calculations are correct, the Dragon’s Breath chili will be crowned the world’s hottest pepper when it’s assessed by Guinness World Records.

Fossilized Fat Shows 550-Million-Year-Old Sea Creature May Have Been the World's First Animal

A bizarre sea creature whose fossils look like a cross between a leaf and a fingerprint may be Earth's oldest known animal, dating back 558 million years.

As New Scientist reports, researchers from the Australian National University (ANU) made a fortunate find in a remote region of Russia: a Dickinsonia fossil with fat molecules still attached. These odd, oval-shaped creatures were soft-bodied, had rib structures running down their sides, and grew about 4.5 feet long. They were as “strange as life on another planet,” researchers wrote in the abstract of a new paper published in the journal Science.

Although Dickinsonia fossils were first discovered in South Australia in 1946, researchers lacked the organic matter needed to classify this creature. "Scientists have been fighting for more than 75 years over what Dickinsonia and other bizarre fossils of the Edicaran biota were: giant single-celled amoeba, lichen, failed experiments of evolution, or the earliest animals on Earth,” senior author Jochen Brocks, an associate professor at ANU, said in a statement.

With the discovery of cholesterol molecules—which are found in almost all animals, but not in other organisms like bacteria and amoebas—scientists can say that Dickinsonia were animals. The creatures swam the seas during the Ediacaran Period, 635 million to 542 million years ago. More complex organisms like mollusks, worms, and sponges didn’t emerge until 20 million years later.

The fossil with fat molecules was found on cliffs near the White Sea in an area of northwest Russia that was so remote that researchers had to take a helicopter to get there. Collecting the samples was a death-defying feat, too.

“I had to hang over the edge of a cliff on ropes and dig out huge blocks of sandstone, throw them down, wash the sandstone, and repeat this process until I found the fossils I was after,” lead author Ilya Bobrovskiy of ANU said. Considering that this find could change our understanding of Earth’s earliest life forms, it seems the risk was worth it.

The Weird, Disturbing World of Snail Sex

Romance is rare in the animal kingdom. Instead of wooing their partners before copulating, male ducks force themselves onto females, depositing genetic material with spiky, corkscrew penises. Then, there's tardigrade sex, which is less violent but not exactly heartwarming. Females lay eggs into a husk of dead skin. The male then ejaculates onto the eggs while stroking the female, and the whole process can take up to an hour.

But you can't talk about disturbing mating rituals in nature without mentioning snails. If you're unfamiliar with snail sexuality, you may assume that snail sex falls on the vanilla side: The mollusks, after all, are famous for being slow-moving and they don't even have limbs. But if you have the patience to watch a pair of snails going at it, you'll notice that things get interesting.

The first factor that complicates snail sex is their genitalia. Snails are hermaphrodites, meaning individuals have both a male set and female set of parts, and any two snails can reproduce with each other regardless of sex. But in order for a couple of snails to make little snail babies, one of them needs to take on the role of the female. That's where the love dart comes in.

The love dart, technically called a gypsobelum, isn't exactly the Cupid's arrow the name suggests. It's a nail-clipping-sized spike that snails jab into their partners about 30 minutes before the actual sex act takes place. The sliver is packed with hormones that prepare the receiving snail's body for sperm. Depending on the species, only one snail might release the dart, or they both might in an attempt to avoid becoming the female of the pair. You can watch the action in the video below.

For sex to be successful, both snails must insert their penises into the other's vaginal tracts at the same time. Both snails deposit sperm, and the strength of the love dart ultimately determines whether or not that sperm fertilizes their partner's eggs.

That's assuming the snail survives the little love-stab. In human proportions, the love dart is the equivalent of a 15-inch knife. Fortunately, snails are resilient creatures, and gastropod researcher Joris Koene tells KQED he's only ever seen one snail die from the transfer.

Snails also have a way of making it up to their partners after skewering them with a hormone stick. Their sperm deposit contains a dose of fortifying nutrients, something scientists refer to as a nuptial gift. It may not equal the energy expended during sex, but its enough to give them a small post-coital boost.
