Horses use 17 discrete facial movements in communication, compared to 27 for people, 16 for dogs, and 13 for chimpanzees. University of Sussex researchers determined this by studying the musculature under a horse's face and watched videos of horses of all ages and multiple breeds. This enabled the scientists to create a catalog of facial behavioral sequences named EquiFACS (Equine Facial Action Coding System.) From National Geographic:
Jennifer Wathan, the study’s lead author, says the similarities between horse movements and human ones are striking. They include raising inner eyebrows (“puppy-dog eyes”) to show fear, surprise, or sadness; pulling back lip corners (smiling) in greeting or submission; and opening eyes wide to indicate alarm...
Her team’s research, which is already helping veterinarians and trainers, could also connect facial expressions to emotional states. “We don’t know much about the emotional lives of animals,” she says. “What does a positive emotion look like? This tool could help us see it.”

I’ve had quite a few fun afternoons playing with dry ice from making spooky fog in the kitchen to exploding plastic bottles in the yard. But I’ve never had the opportunity to pour hot lava over dry ice. In this video, the lava is 1400 °C and the dry ice is -78C°. So cool! And […]
A Boston University team have developed an acoustic, 3D-printed metamaterial whose topology is such that it reflects 94% of human-audible sound; the researchers' demonstration involves inserting a ring of this stuff in a PVC pipe and blasting a speaker down one end: light and air emerges from the other end, but sound does not.
Scientists Lior Appelbaum and David Zada in Israel publish new proof that sleep serves to help our brains repair damage.
Big companies want automation on a big scale. Doing that means diving into the tricky world of machine learning and data science.

Big systems need tight security – and the experts who can implement it. Cisco Networking Systems are the go-to providers for network infrastructure, but maintaining it takes a lot of up-to-date knowledge. If you want that knowledge right from the source, there’s an online course that can get you certified painlessly: The Foundational Cisco CCNA […]
Computer slowing down? There are a ton of reasons why that might be, especially if your unit has a few years on it. Junk files and programs can accumulate over time, some even left over from otherwise uninstalled software. This virtual debris can slow your PC down dramatically, but there’s a surprisingly quick fix. Lauded […]
