Delivery Drones Use Bird-Inspired Legs to Jump Into the Air

Passerine’s fixed-wing drones can take off (and land) using a pair of legs Drones have a fundamental design problem. The kind of drone that can carry large payloads at high speeds over long distances is fundamentally different from the kind of drone that can take off and land from a small area. In very simple…

Demand and Salaries for Data Scientists Continue to Climb

Data science job openings are expanding faster than the number of technologists looking for them, says job-search firm Indeed Back in August, a LinkedIn analysis concluded that the United States is facing a significant shortage of data scientists, a big change from a surplus in 2015. This week, job-search firm Indeed reported that its data indicates…

Hail the Perovskite Transistors

Researchers have created a field-effect transistor using a single-crystal, “paint-on” perovskite Transistors, and the conductive traces that connect them, are routinely created by the billions on the surface of silicon wafers, which are later cut into the individual “chips” that power our computers, phones, watches, and countless new electronic gadgets. But few people think much…

A Choice of Grippers Helps Dual-Arm Robot Pick Up Objects Faster Than Ever

Dex-Net 4.0 enables “ambidextrous” robots to choose the best gripper for the job We’ve been following Dex-Net’s progress towards universal grasping for several years now, and today in a paper in Science Robotics, UC Berkeley is presenting Dex-Net 4.0. The new and exciting bit about this most current version of Dex-Net is that it’s able to…

San Diego’s Smart Streetlights Yield a Firehose of Data

San Diego’s installation of 3,200 smart streetlights is slightly behind schedule, but the city has already ordered more San Diego’s network of smart streetlights, which has been rolling out since early 2018, continues to grow. To date, a few 2,000 of the sensor-laden devices have begun gathering pictures, sounds, and new data. So far, the city…

A Bizarre ‘Ice Circle’ Is Turning Heads in Maine. Here’s the Science Behind It

Nature loves to make things round: planets, soap bubbles, oranges, eyeballs, the circular swirl of a spinning hurricane. A lot of forces are at play in favoring natural circles and spheres—the equalizing force of air pressure pushing out or gravity pulling in; the rotation of the Earth, creating vortices in air; the evolutionary imperative of…

Zoom and Focus: These Familiar Video Features are Coming to Audio

Imagine taking photos or videos without the ability to zoom and focus. Nokia says audio recording should have the same tools I’ve certainly shot videos with my phone only to find out later that the audio part of the recording captured the conversations around me rather than the sounds coming from the subject of the…
