Eggs may seem boring to the average person. But do not be fooled. These pointy objects can communicate in the nest and explode in the face of the unwary. Mammal eggs may lack shells, but they have their moments. Conception is a sparkly business, and mouse eggs once held a mammoth. Then there was the

Of the crazy and speculative theories out there (and there are many as we all know), those that revolve around the notion that human beings are not indigenous to the Earth are perhaps the craziest. The idea is that we, or rather our ancestors, were brought here from another world, most likely as prisoners condemned

Unlike Earth, every new planet we have discovered has been hostile to us. Some could become habitable if we figure out the answers to a few problems, like the unavailability of oxygen and water. Others would still be unsuitable for human life. These deadly planets are ready to kill any creature that strays too close

Across the world, many people over the years have disappeared, seemingly into thin air, with no satisfying explanation. The mystery is only deepened when neither the missing person nor their remains are ever seen again. However, there have also been many cases of people who disappear in the most mysterious of circumstances, only to reappear—sometimes

But photos and brown-varnished paintings do not tell the whole story. To make those paintings in the first place, people had to search out

Sweat cools down the body. It may even betray a nervous mind. But for scientists, it is so much more. Its chemicals improve athletic performance and reveal the strange influence of male sweat on both genders. Inventions in this field are peculiar—from perspiring robots to sweat-sensing clothing that offers coolness. As improbable as it sounds,

The dangers of space travel are well understood. Lists of its casualties include the entire Apollo 1 crew (Gus Grissom, Edward White II, Roger Chaffee) and the entire team of cosmonauts on the Soyuz 11 (Georgi Dobrovolski, Viktor Patsayev, Vladislav Volkov). The business of space travel is a risky one. Since the 1960s, more than

Losing a child is every parent’s worst nightmare, a permanently life-altering event that turns their world upside down. Such tragedies are arguably at their worst when foul play is involved or when a child simply vanishes, leaving the parents deprived of closure. Some parents who have lost a child in extreme circumstances will take their

Dedicated to probing the unknown, the National Aeronautics and Space Administration (NASA) has designed its fair share of unusual studies. Tasked with keeping astronauts safe, they threw lunar dust at oysters and had a man sniff at 800 space-bound items. Curiosity also saw their scientists turn photographs into music and create oceans in cups. NASA’s

A lot of people enjoy a nice, scenic hike in the woods. Getting out into nature is relaxing and good for the soul. It’s fun to do it at least once in summer or autumn. Unfortunately, this list will not make you want to go hiking. That is because David Carpenter (aka “the Trailside Killer”)
