Why Does Exercise Start Hurting Two Days After a Workout?

If you’ve decided, this year, to start working out, you might have noticed a strange phenomenon: You’ll leave the gym feeling fine, and then two days later wake up sore. This weird time-lag appears unique to exercise, and is, when you think about it, kind of inexplicable—like stubbing your toe, feeling nothing, and then two days later suddenly yelping in pain.

Can You Eat So Much That You Die?

Can you eat yourself to death in one occasion of very excessive eating? We know that the West's overeating problem is bad, albeit gradual: No one’s ever died from eating three Big Macs, but plenty of people may have died from eating three Big Macs twice a week for thirty years (some, miraculously, have managed to avoid that fate). But what about the bingers? The people who, during Christmas, or after receiving a bit of horrific personal news, find themselves eating way more than they’re used to? You don’t need to be an addict to overdose on drugs; might the same apply to food? Read More >>

What’s the Ideal Number of Humans on Earth?

Earth might be looking a little worse for wear, after the last four hundred years of reckless wide-scale resource extraction, but to its credit it hasn’t collapsed entirely. Despite our best efforts, it continues to gamely welcome our rapidly expanding population, barring the occasional earthquake. Whether the planet might be a little better off with fewer of us is a different question, a freighted one. Read More >>

What Do Porgs Taste Like? 

Move over Ewoks, there’s a new critter in this galaxy. Star Wars: The Last Jedi marks the debut of porgs, a species of alien birds that chill with Luke Skywalker on Ahch-To as he trains Rey in the ways of the Force. They may be cute, but we can’t help but wonder: How do they taste? Read More >>

Why Do We Get Allergies?

Corporeality can be, at times, pretty great. And yet for all its advantages, there are certain downsides to being trapped in a sack of rotting limbs and organs and eye-juice. For instance: Allergies. There are innocent people out there who can’t pet a friendly dog without sneezing, or eat a peanut without instantly dying. Read More >>

How do Animals Recognise Each Other?

To be a giraffe among giraffes, or a pigeon among pigeons, is to live at all times in that scene from Being John Malkovich — a world in which everyone you know looks pretty much exactly like you. However wondrously varied the animal kingdom might be, on a species-level its residents tend to look more similar than not — at least, from a human perspective. I’m not saying that all squirrels look identical — just that being a squirrel, and trying to distinguish your squirrel-spouse from your squirrel dad from your squirrel-mailman, seems like it would be pretty hard work.

When Will We Have Designer Babies?

Within 20 to 40 years, sex will no longer be the preferred method of reproduction. Instead, half the population with decent health care will – no shitting you – have eggs grown from human skin and fertilised with sperm, then have the entire genome of about 100 embryo samples sequenced, peruse the highlights, and pick the best model to implant. At least that’s what Stanford law professor and bioethicist Hank Greely predicts in The End of Sex and the Future of Human Reproduction. But skin-grown humans aside, how long until we have “designer babies”? Read More >>

Can Joker Venom Be Real?

As long as there has been a Joker—and we’re going on eighty years with this guy—there has been, as well, a Joker venom. It debuted alongside him, in 1940s Batman #1, and has been a part of his arsenal ever since. Read More >>

Why Do People See Ghosts?

You live and then you die and then you rot in a hole—or so say the elites, with their glasses, and their PhDs in neuroscience. This bummer reality has never appealed much to Americans, 72% of whom believe in some kind of afterlife. It’s a comparatively rarer, though still sizeable, breed of American who believe in some spectral middle ground, in which, instead of rotting or going to hell, you float around and freak out your kids, or the new residents of the house where you were brutally murdered a hundred years ago.

What’s the Worst Taste in the World?

There was a time, not so long ago when, for fun, or just for something to do, millions of people would tune in to watch non-actors eat worms for cash. It felt good, watching strangers wreck their intestines. Things might not have been going your way, but at least you weren’t competitively chewing cockroaches on television. Read More >>

Is Eating Synthetic Human Flesh Cannibalism? 

A disgusting factor which separates consuming human flesh from consuming muscle tissue of non-speaking animals is that you can’t separate eating dead humans from eating live humans. In the way that you call a baby cow “veal” or a pig “pork,” human flesh is just human flesh—you wouldn’t think about eating Dave’s “rounds” or his “snout,” you would think about eating Dave’s ass and face.

Should You Be Allowed to Sell Your Kidney?

There are currently 96,559 candidates on the list awaiting a kidney transplant in the US. In major cities, the average wait is five to ten years. For those on the list, there are meagre options to get off it. They could receive a kidney donation from a relative or a friend. Internationally, some have opted for a murkier route. In 2012, the World Health Organization reported an influx of people taking “transplant tours” to countries like China, Pakistan, or India for often poorly regulated and illegal operations. (Currently, Iran is the only country where it is legal to sell your organs, but not to foreigners). The WHO estimated 10,000 operations involving “black market” organs per year. Read More >>

What Would Happen If Everyone in the World Lost Their Sex Drive?

Online dating apps, pornography, advertising, and the continued existence of the human race all testify to a healthy, ongoing interest in sex among human beings, despite the fact that millennials appear to be having less of it. Until the day pills or radiation extinguish the last embers of human horniness, sex will likely continue to shape and govern society in all kinds of ways. Read More >>

Is Playing an Evil Clown Harmful to Your Mental Health?

With their fanciful costumes and comedic personas, clowns seem like the epitome of joy. But these figures of fun also provoke a horrified response and have even inspired their own phobia. Although it’s not officially recognised in the American Psychiatric Association’s DSM-5 categorisation of disorders, coulrophobia, the fear of clowns, is one of the most commonly known phobias in the public perception. It’s easy to see why clowns are sometimes viewed as icons of fear. Permanent, frozen smiles and uncanny, mask-like makeup inspire nightmarish visions. Read More >>
