    A dinosaur’s running gait may reveal insights into the history of bird flight

    An early winged dinosaur couldn’t fly, but it could run. Now, with assists from a robotic dino and young ostriches wearing artificial wings, a study suggests that the dinosaur’s running gait caused its wings to flap, in what may have been an evolutionary precursor to flight.

    Caudipteryx was a peacock-sized dinosaur with feathered and winglike forelimbs that lived about 125 million years...

    An AI used art to control monkeys’ brain cells

    New artwork created by artificial intelligence does weird things to the primate brain.

    When shown to macaques, AI-generated images purposefully caused nerve cells in the monkeys’ brains to fire more than pictures of real-world objects. The AI could also design patterns that activated specific neurons while suppressing others, researchers report in the May 3 Science.

    Can Silicon Valley entrepreneurs make crickets the next chicken?

    Trina Chiasson was raised in a log cabin, learned to spin plates in Chicago’s circus arts community, dreamed up a software company and three years later sold it to a bigger company. Her next challenge: building a business, called Ovipost, that brings better technology to cricket farming.

    “I didn’t know any cricket farmers growing up, I know you’ll be shocked to learn,” she says. Yet she’...

    A science-themed escape room gives the brain a workout

    Professor Schrödenberg is missing, and evil agents want to use her quantum computing research for nefarious purposes. Stopping them is up to you, but completing your mission will require solving some mind-bending puzzles —based on science.

    If you are up for the challenge, you can test your wits at LabEscape, a science-themed escape room at the Lincoln Square Mall in Urbana, Ill. Escape...

    How we reported a controversial story about the day the dinosaurs died

    This is part of the Transparency Project, which explains how we do science journalism. This article refers to a story published in April 2019, “New fossils may capture the minutes after the dinosaur-killing asteroid impact.”

    How did you find this story?

    This was an unusual story for us because it was based not only on a research paper published in a scientific journal, which is the type...

    Introducing the Transparency Project

    Here at Science News we work hard to make sure that our coverage of the latest advances in science, medicine and technology is clear, accurate and comprehensive. But we realize that what’s clear to us about how we do science journalism may not be clear to our readers. And we want to be open and accountable about that process.

    So we’re launching the Transparency Project. In the coming...

  • 50 years ago, scientists fought over element 104’s discovery

    Another route to 104 —

    In 1964, a few radioactive atoms existed for three-tenths of a second in a Soviet laboratory, and G.N. Flerov and his colleagues, who detected it, announced the discovery of element 104. But the announcement was met with skepticism in the United States.… Now, U.S. scientists declare they have gone their own route to corral the elusive element. — Science News,...

    See beautiful fossils from top Cambrian sites around the world

    For most of the nearly 3.5 billion years of documented life on Earth, creatures were simple, dominated by organisms such as bacteria, algae and fungi (SN: 10/13/18, p. 10).

    Then, beginning about 541 million years ago, life quickly diversified into an array of new, complex forms. This flourishing, called the Cambrian explosion, took place within about 25 million years. Fossils from the...

    ‘An Elegant Defense’ explores the immune system’s softer side

    An Elegant DefenseMatt RichtelWilliam Morrow, $28.99

    We like to think of the immune system as our own personal military, ready to attack foreign invaders. Slice your finger, and immune cells rush in to destroy rogue pathogens.

    But it’s misleading to think of the immune system as solely a war machine. It must also keep the peace, assessing each threat and, in many cases,...
