Vinegar Eels Can Synchronize Their Wiggling as They Move Together in SwarmsThe Turbatrix aceti is a species of nematode commonly found wiggling inside jars of raw vinegar or in fish tanks. Better known as vinegar eels, these harmless and non-parasitic worms are one of many intriguing creatures in the microscopic world.Scientists have recently discovered that vinegar eels can "wiggle in synch as they move together in swarms" — an ability rarely found in nature. There are animals such as birds and fish that can move collectively. This nematode species, however, according to University of Rochester physicist Anton Peshkov, has "a combination of two different kinds of synchronization," namely motion and oscillation.Their ability to synchronize their movements and oscillation can be seen in this short clip. More details about them can be read over at ScienceNews.Scientists are still wondering why these tiny worms exhibit such behavior. Is it a ritual? Is it a dance? Only they know.Image Credit: Anton Peshkov via ScienceNews#worm #Weird #InterestingScience #Wiggle #Nematodes #VinegarEels #synchornization

"Everlasting Bubbles" that Never Pop Created by PhysicistsWe've all played with soap bubbles when we were children. We've either watched them slowly fade away as they floated or popped them just for fun. But even now, years later, we still find soap bubbles as satisfying and fascinating as they were when we were children. Scientists, physicists, and mathematicians would probably say the same. Some scientists have recently been looking into extending the lifespan of soap bubbles, and they have made "everlasting bubbles." Of course, these are not really everlasting, but they last up to 465 days, which is, I think, a really long time for a bubble. The secret to the long life of the bubble?

Crocodile Eyes are an Engineering Marvel: Three Eyelids, Retractable in Battle and Night VisionFor predators, the sense of sight is the most important to have. Perhaps this is why crocodiles are considered the most dangerous predator in the world. Among all the known predators, crocodile eyes might just be the best one out there.It is assumed that, like human eyes, crocodile eyes can see in color. Similar to cat eyes, they can also see at night. But perhaps the most excellent feature that crocodile eyes have is the ability to see underwater, thanks to the protective membrane on them.And that's not all. Thanks to the positioning of their eyes, crocodiles can track multiple moving targets, which makes their eyes more intriguing.Of course, a great asset such as this one needs protection as well. And that is why crocodiles can draw back their eyeballs back into their sockets when they are attacked.What are the secrets to their impressive eyes? This video from the Smithsonian Channel provides us with the answers.(Image Credit: Smithsonian Channel via YouTube)#Crocodile #Predators #InterestingScience
