This jumping spider mimics the movements of ant species in its environment to avoid being eaten. The spider’s predators, such as praying mantis, pass up anything that might be an ant to avoid the ants' painful bite.

Science News Video: After 50 years, Lucy faces rivals with other human ancestors
In 1974, paleoanthropologist Don Johanson and student Tom Gray unearthed a 40% complete skeleton of an early human ancestor, fundamentally changing the human family tree. The specimen acquired a nickname that persisted: Lucy, after the Beatles song playing at the fossil hunter’s camp--“Lucy in the Sky with Diamonds.” At 3.2 million years old, some thought her species, Australopithecus afarensis, was close to when the ancestor of humans had split from the ancestor of chimpanzees. But in the past 50 years, discoveries of hominins both older and the same age as Lucy have pushed that split millions of years deeper in time, and challenged her position as mother of us all.

Science News Video: Soccer-playing robots teach themselves to score
Developing athletic ability requires practice, even for robots. Using an approach driven by trial and error called deep reinforcement learning, researchers at DeepMind helped these soccer-playing robots develop skills, agility, and techniques to improve their play--all at a higher level than could be manually programmed. The computer “agents” controlling the robots picked up the rules and nuances of the game by observing human soccer players, then playing against each other in both simulations and using real-life robots. Robots play each other to improve their game, get computational “coaching,” and even mimic defensive moves of human players. While these athletic machines may not be making starting lineups anytime soon, computer scientists hope that this ability to learn and perform complex tasks in unpredictable environments will prove useful well beyond the soccer field.

Science News Video: Why are these #frogs such clumsy jumpers?
Scientists have figured out why some miniaturized frogs from Brazil are such clumsy jumpers. A 2022 study published in Science Advances reveals that among adult vertebrates, members of the genus Brachycephalus have the smallest known semicircular canals – the part of the inner ear necessary for maintaining balance and spatial orientation.
The diminutive size of these canals results in low sensitivity to angular acceleration, preventing the frogs from controlling their posture as they prepare to land.

Watch those episodes now, and many more from Wild Hope, right here on YouTube—or follow @wildhopetv on Instagram to discover countless more stories of changemakers working to restore biodiversity around the globe. Change is closer than you think.
Even when a species has officially gone extinct, there's sometimes still hope of saving it. Scientists keep insurance populations of endangered animals all over the world with the goal of one day reintroducing them to the wild.

Science News Video: Watch bacteria found on our teeth rapidly divide and grow | Science News
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.

With the recent boom in clean energy development, more and more farmers are interested in leasing their fields to solar power utilities, often forcing them to abandon traditional crop production or grazing in the process. Now researchers in the growing field of agrivoltaics hope to provide scientific insights and guidance to make it possible to produce food and power at the same time. While sheep grazing on solar farms has already demonstrated feasibility and ecological benefits, these researchers are discovering that co-locating crops and solar panels may prove to be a tough row to hoe.

Caption: To see exactly how globular springtails do backflips, researchers had to use a high-speed camera. What they found was astounding: When a springtail lifts off, it travels as fast as 1.5 meters per second and can spin up to 29 times in the blink of an eye.
