Galileo is considered one of the greatest astronomers of all time. His discovery of Jupiter’s major moons (Io, Europa, Ganymede and Callisto) revolutionized astronomy and helped speed the acceptance of the Copernican Model of the universe. However, Galileo is also known for the numerous scientific inventions he made… »
We know the Cleopatra’s sails were dyed with Tyrian purple. We know that Roman emperors dyed their new robes Tyrian purple as a sign of wealth. What we don’t know, exactly, is what this legendary purple looked like. But we do know where it comes from—namely, “snail milk.” »
In 1845, a meter-long iron rod pierced the skull of Vermont railway worker Phineas Gage. The resulting changes to his personality forever changed our perception of the human brain. But what happened next to Gage is rarely covered in textbooks — a problematic oversight, say psychologists.
By editing a single gene, researchers from South Korea and China have engineered pigs that produce about twice the amount of muscle as normal pigs. The goal is to produce leaner meat and at higher yields, but early results show it could be a long time before this jacked-up pork appears on your dinner plate. »
Anne of Green Gables is a children’s classic and deservedly so. In one dramatic scene its heroine, Anne Shirley, uses ipecac to save a dying child. Here’s what ipecac would actually have done, and why it fell out of favor. »
You probably don’t know your cat as well as you think you do. According to a recent survey of cat owners in the UK, most people are pretty clueless about their cats’ lives. »
SpaceX experienced yet another setback this past Sunday when its Falcon 9 rocket exploded two minutes after launch. The company is still not sure what went wrong. Here’s a clip of the incident — including the separation of the CRS-7 Dragon — in slow motion. »
The Earth has heated up and cooled down repeatedly, according to scientists. And we believe them— but how do they actually know? We’ll tell you how scientists know, today, that an Ice Age occurred millennia ago. »
A number of math problems have recently garnered considerable attention, but the inability to solve these problems quickly is not indicative of a person’s overall math skill, nor should it prompt a crisis of confidence about the state of American math aptitude. »
One of the most famous tricks in chemistry is “The Rope Trick.” First discovered in 1959 by the chemist who went on to invent kevlar, this lets chemists pour two liquids into a glass . . . and then pull out a seemingly endless nylon rope from between the still-separated-liquids.
A slew of articles are claiming that an “exasperated” artificial intelligence snapped at its programmer during a conversation about morality and ethics. Sadly, it’s another example of the media overselling the capabilities of simple chatbots.
If you’ve wandered through a wood and idly peeled back the bark of a tree, you may have found a little expanse of silk, like a nest, with insects stuck inside. If you thought that those insects were the prey of a spider, you might have been right, or you might have been looking at the only known stop on an early… »
Science is meant to be an unceasing, always-sceptical search for knowledge, so it’s not often that scientists can call it a day, declare a problem all scienced out, and move on. But that’s exactly what the team counting asteroid craters on Earth are doing. »
So, that Internet apocalypse that’s going to befall us when our fiber optic cables max out? Maybe not so much. On Thursday, engineers reported in Science that they’d broken the “capacity limit” for fiber optic transmission, opening the door to future networks that carry more data further at lower costs. »
The discovery of Pappochelys, a Triassic-era reptile with a set of emerging turtle-like features, is helping scientists fill in an important evolutionary gap. »
When was the last time you thanked the bugs in your belly? Even if the concept of a “healthy” microbiome is flawed, the trillions of microorganisms living in your gut (and mouth, and vagina, and nose, etc.) play a vital role in many of your body’s functions. They’re so essential, many refer to the microbiome as an… »
The ocean sunfish is so improbable that even it looks astonished that it exists. The size alone is crazy. It can weigh up to 2,200 pounds, and grow to be the size of a small car that has been squashed flat by a larger car. How it does this is, mostly, a mystery.
