Technology AI Homemade chess board moves its own pieces. Maker Joshua Stanley Robotics used magnets and an open source chess platform to build this unique board. Breakthroughs, discoveries, and DIY tips sent six days a week. It's been nearly 30 years since chess champion Garry Kasparov lost to IBM's Deep Blue, marking the first time a reigning world champion was defeated by a computer in a match. Chess engines have since improved so dramatically that even a simple smartphone app can now make top grandmasters sweat .

HoloRadar helps give the vehicles a more complete picture of their surroundings. Breakthroughs, discoveries, and DIY tips sent six days a week. In late January, an Alphabet-owned Waymo self-driving car was cruising near an elementary school in Santa Monica, California, when a young child suddenly darted into the street . Waymo's LiDAR sensors detected the student, who had just emerged from behind a parked SUV, but it was too late. Despite slamming on the brakes and slowing from 17 to six mph, the driverless car struck the child, knocking them to the pavement.

Sports pushes the science of keeping time forward. A broadcast drone hovers as Britain's Makayla Gerken Schofield competes in the freestyle skiing women's moguls. Breakthroughs, discoveries, and DIY tips sent six days a week. Athletes competing in this year's Winter Olympic Games in Milan will do so surrounded by a complex web of AI-enabled cameras, stopwatches, sensors, and fast-flying drones capable of tracking performance down to fractions of a second. The high-tech timekeeping system, the culmination of nearly a century of constant iteration, is fundamentally reshaping how viewers at home experience the Games.

Technology Engineering Synthetic skin reveals hidden'Mona Lisa' when exposed to heat The octopus-inspired material could lead to better camouflage technology for the military and beyond. Breakthroughs, discoveries, and DIY tips sent six days a week. Octopuses and their cephalopod cousins have long fascinated biologists with their seemingly supernatural shapeshifting. The cephalopods rapidly change color and texture, blending into their surroundings and evading predators. This natural camouflage is a remarkable bit of biology that engineers have tried to replicate, albeit with limited success.

Technology Engineering Man solves ceiling fans' most annoying problem His 3D-printed device finally shows a ceiling fans' speed. Breakthroughs, discoveries, and DIY tips sent six days a week. Anyone who's used an overhead ceiling fan knows it can be a pain to work. Yanking its chain gets the motor running, but there's no easy visual indication of what speed setting the fan is on. The blades can also take a frustratingly long time to reach their full speed.

Your tone does more than startle your pet. Breakthroughs, discoveries, and DIY tips sent six days a week. Whether it's the sound of food being poured into a bowl or the front door opening, a dog's ears are on alert. Noises picked up by their highly-attuned senses can also affect their balance. A small study in Austria found that balance is stabilized and destabilized when dogs hear both happy or angry human voices.

'Nature seems to have already solved the problem.' Breakthroughs, discoveries, and DIY tips sent six days a week. To help figure out what makes stingrays such unique and unusual swimmers, a team of mechanical engineers at the University of California, Riverside (UCR) created a wavy robotic fin. After submerging the robot in underwater tunnels designed to mimic swimming near the sea floor, their tests indicate that different types of ray species may have evolved alternative swimming techniques that best suit their setting. Specifically, the findings suggest that some ray species swimming near the seafloor adjust the way their fins move and tilt to counter a downward force that would otherwise pull them toward the ground. It turns out that stingrays gracefully gliding along waves near seabeds aren't doing it to look cool.

Breakthroughs, discoveries, and DIY tips sent six days a week. Engineers in Switzerland recently created a detachable, spider-like robot hand capable of grabbing multiple objects and using its fingers to crawl. The unsettling device, reminiscent of a threatening video game creature, can separate itself from a mounted robot arm, tip-toe (or really, tip-) its way toward small objects, pick them up, and carry them on its back. The symmetrical design and flexible fingers mean that the robot can transport objects on either side of its body. For humans, that would look like holding a ball in your palm while simultaneously grasping a piece of fruit on the back of your hand.

The lesser long-nosed bat (Leptonycteris yerbabuenae) is a medium-sized bat found in Central and North America. Breakthroughs, discoveries, and DIY tips sent six days a week. Biologists and engineers have joined forces to build a new robot bat that's helping us understand how bats use echolocation to hunt for food. By creating a robot that can echolocate, the team mimicked a bat's flight path and explained how bats can quickly determine whether or not their prey is on a leaf. This new bat's eye view is detailed in a study recently published in the The study was led in part by bat scientist and Smithsonian Tropical Research Institute research associate Inga Geipel .

Police say at least 25 kids used e-bikes and scooters to evade arrest and intimidate drivers. Breakthroughs, discoveries, and DIY tips sent six days a week. Australian police are cracking down on groups of unruly teenagers who they say are using deceptively speedy e-bikes and scooters to engage in "antisocial riding behavior." Their solution: confiscate the popular micromobility devices and crush them. The roundup, dubbed Operation Moorhead, began last week in the suburbs of Perth in southwestern Australia.
