Bellies full of microplastic rob baby fish of their basic instincts Larval European perch that has ingested microplastic particles (light-colored spheres on bottom side). Photo by Oona Lönnstedt When exposed to microplastics, baby fish stop eating natural food and prefer consuming the pollutant, according to a report from ecologists at Uppsala University in Sweden. The dietary switch derails the basic instincts of the fish, the researchers found, elevating the likelihood of being caught by predators. The findings may explain why populations of European perch (Perca fluviatilis) — the main species analyzed in the study — have declined in the Baltic Sea.

Nonverbal Communication for Human-Robot Interaction: Henny Admoni Robotics has already improved lives by taking over dull, dirty, and dangerous jobs, freeing people for safer, more skillful pursuits. For instance, autonomous mechanical arms weld cars in factories, and autonomous vacuum cleaners keep floors clean in millions of homes. However, most currently deployed robotic devices operate primarily without human interaction, and are typically incapable of understanding natural human communication. Inc.

NOVA - Official Website Can Wind Turbines Make You Sick? Residents living in the shadows of wind turbines say the sound is making them sick. But so far the science isn't there. From NOVA Next | Jun 27, 2018 Thirty Years Ago Today, Global Warming First Made Headline News Rustic Strawberry Tart I’ve been making variations of this rustic tart since last fall. And, for that, I’m sorry. Sorry, that is, for holding out on you until now. Because a recipe this adaptable, relatively guiltless and delicious should clearly be shared. Since I discovered this recipe last fall, I’ve been making the pastry and stuffing it with pretty much anything I can think of. Wallpaper Camera Wraps Around Any Surface What if you could wrap a camera around your car (or tank) for a 360-degree view or encircle a streetlight to boost security? You might even use it as wallpaper to check out what’s happening in the room next door. This idea may have taken a step closer with a new thin flexible sheet camera design by researchers at Columbia University.

Mathematicians are not so different from naturalists. Rather than studying organisms, they study equations and shapes using their own techniques. They twist and stretch mathematical objects, translate them into new mathematical languages, and apply them to new problems.
Why Do We Count? The abacus is a tool, just like the calculator is a tool. Your smartphone’s calculator app — that’s a tool, too. But are numbers themselves a tool? That’s the case Caleb Everett makes in his new book, “Numbers and the Making of Us: Counting and the Course of Human Cultures.” Anonymity in science - ScienceDirect Outline A brief history of anonymous scientistsScientific anonymity todayAnonymity and objectivity?When is anonymity appropriate? Industry sees new opportunities for space manufacturing HOUSTON — Space manufacturing, a field whose promise has gone unrealized for decades, is now offering new opportunities thanks to the use of the International Space Station and reduced space access costs, some experts believe. The best near-term opportunity to demonstrate the ability of space manufacturing to produce products of value on Earth, according to a panel at the SpaceCom Expo here Dec. 6, may come from experiments flying to the station in the next year to test the production of high-quality optical fibers. “The opportunities for in-space manufacturing have never been better,” said Lynn Harper of the Space Portal Office at NASA’s Ames Research Center. “Large-scale manufacturing could be tested and perfected on the ISS, and then implemented in the many commercial carriers that are starting to emerge.”
