Play 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.

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.

Play 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.

Play 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.

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. Video: Thomas MacGillavry and Joris De Raedt

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.

Play Video: What is agrivoltaics? | Science News

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.
