It’s (relatively) easy to get water droplets to move at terminal velocity. They don’t even have to be moving relative to you. Just get air flowing upwards fast enough, and the water will hover, without increasing its speed up or down. Then throw more water drops at it, and see what happens. »
Ankylosaurs are common features on documentaries or animated films about dinosaurs. Their armored body and club-like tail make them easy to identify. But how did that tail actually evolve? Evolutionary biologists show us the “first draft” of a popular dinosaur. »
When you get a package of dry beans examine the cooking instructions on the side. Most likely they’ll stress that after you’ve soaked your beans in water for an hour or two, you should discard the water before cooking the beans very, very well. That’s not just a culinary tip. Undercooking your beans can cause extreme,… »
The best way to study the subatomic particles that make up the most fundamental building blocks of our universe is, of course, to smash them into each other with as much energy as possible. And now physicists at SLAC National Accelerator Laboratory say they’ve found a better way to do that. »
Boom! Even if a feather dropped on or a mosquito landed on or like a heavy piece of dust managed to get on top of nitrogen triiodide, an immediate dark purple explosion happens. It’s because nitrogen triiodide is so unstable that it detonates when it’s disturbed, even slightly. Here’s it firing off in slow motion. »
Neurologist and writer Oliver Sacks passed away today at the age of 82. Sacks is best known for his writing, which brought neurological case studies to life for a general audience. »
Watching a fringe-lipped bat swooping down to eat a tungara frog will give you a new appreciation for bats as predators. It will also give you a new appreciation for how much male frogs want to mate. »
We know that some bee larvae develop into queens and other bee larvae develop into workers because they were fed differently. Until now we didn’t know what “ingredient” in the food made queens. It turns out to be not an additive but an absence that makes workers. »
One of the most important experiments in the world manages to fly under most people’s radar. After years of patient experimental work, two scientists managed to figure out how one code in DNA translated into an actual, physical protein.
Cyanide poisoning is not a nice way to go. Essentially it’s open-air suffocation. Cyanide ions in the body interact with an enzyme called cytochrome oxidase. This enzyme works with hemoglobin in the blood. It preferentially picks up cyanide when it should be picking up oxygen, meaning the body slowly dies for lack of… »
This is the ultimate video to illustrate that “the dose makes the poison.” ASAP Science explains how much seasoning, how many cherry pits, and how much loud music will murder you. »
As much as we like to marvel at the power and majesty of the ocean, we have to admit that as beautiful as it is, it also stinks. It stinks because it’s shot through with sulfur. And that sulfur has seen the insides of two different creatues before it got to your nose.
Earth is the only planet in our Solar System where life is known to exist. Note the use of the word “known,” which indicates that our knowledge of the Solar System is still in its infancy, and the search for life continues. However, from all observable indications, Earth is the only place in our Solar System where… »
Pierre-Simon Laplace lived from 1749 to 1827 and was busy the entire time. He wrote books, worked in politics, and figured out the secrets of the universe. One of those secrets he quietly withdrew from later copies of his books. Pity. »
There’s bad news and there’s good news in this post. The bad news is proteins from your own body accidentally smuggle radioactive metals into you. The good news is that those proteins can make those materials glow. »
The health tip about drinking eight 8-ounce glasses of water a day has been roundly dismissed by scientists, doctors, and upstanding bloggers for years, but this baseless myth refuses to die. Meanwhile, exercise-associated hyponatremia, a consequence of overhydration, is being reported across a broader range of… »
Allonautilus scrobiculatus is a species of nautilus that hasn’t made an appearance for over three decades. Take a look at how it compares to a more common species of nautilus, and learn how nautiluses are more isolated than you might think.
