Ten seconds before it charges, a marlin "turns on" its stripes. Then, when the attack is done, the marlin dials the contrast back down. Layers of colorful cells in their skin rapidly change shape to create the strong pattern.

Science News Video: What makes fighting fish so feisty?
New studies combining genetics and neuroscience offer clues
Centuries of selective breeding of Siamese fighting (betta) fish (Betta splendens) have produced the elaborate colors and patterns that have made them popular pets. But their early domestication was focused on a different signature trait: aggression. In this video, Andrés Bendesky and his team at Columbia University describe how they’ve combined genetics and neuroscience to understand what puts the fight in these fish. The work could help the team and other scientists understand how genes, neurons, and aggression are linked in a variety of animals, including humans.

It's not just for fun, those preservatives are all there to keep you and your food safe. Let's talk about a few of the most common preservatives, what they do, and why you probably don't need to worry about them.

You've probably heard the rule that you cannot travel faster than the speed of light (in a vacuum). And this is true.
You may also have heard that you cannot travel precisely AT the speed of light. But this is false...because you are, in fact, ALWAYS traveling at c. Good ol' Relativity can explain why.

Some of the coolest and most detailed fossils around aren't found in rocks - they're found in amber, a hardened tree resin that can preserve things in incredible detail. From dinosaur feathers to spider webs, and even more, here are a few of the coolest fossils that paleontologists have found in tree juice. Plus, SciShow Rocks Box members can join the hunt by looking at what's in their own pieces of amber!

Science News Video: See a vampire bat treadmill workout | Science News
Researchers put vampire bats through their paces to discover what fuels their metabolism. After a fine meal of cow blood, bats were put into a closed mini-gym with a moving floor. As the bats walked and then — as the treadmill sped up — ran, researchers checked bat breath for signs that amino acids from the cow blood were getting metabolized in the workout. Unlike most mammals burning carbs and fats during exercise, bats metabolize more amino acids.

Science News Video: See how a male Victoria’s riflebird courts a female | Science News
A sit-and-wait flirter, a male riflebird (left in the first clip) puts on a high-energy — and noisy — show for a female visiting his perch. The most flexible wrist joints yet measured in a bird let him curve his dark wings like a flaring cape. Opening and closing his beak, as seen in the first slow motion clip, adds flashes of gold from the mouth and throat lining. Between flashes, he closes his beak to scrape it over the spread feathers for the show’s thwackity-thwack soundtrack, as seen in the second slow motion clip. Scientists previously thought the birds somehow clapped their wings together to make the sounds.

The filamentous bacterium Corynebacterium matruchotii, found in human dental plaque, has a superpower. It can divide into as many as 14 daughter cells at once, allowing it to rapidly expand its territory. In this video, a single cell divides into many, which also divide into many, and so on until the colony rapidly fills the field of view.

This animation shows how the ambipolar electric field works. The most abundant gas in the lower atmosphere, the part we live in, is nitrogen (N2, shown around seven seconds). Pan up to the ionosphere (14 seconds), though, and you’ll find more atomic oxygen. Photons from the sun can collide with oxygen and knock one of their electrons loose, leaving a positively charged oxygen ion behind. The pull between those ions and their lost electrons is the ambipolar electric field, which ties them together.
