Applying electricity for a few seconds to a soft material, such as a slice of raw tomato or chicken, can strongly bond it to a hard object, such as a graphite slab, without any tape or glue, a new study finds. This unexpected effect is also reversible—switching the direction of…

Squeezing Ultra-Precise Optical Timing Onto A Chip

19 Μαρτίου 2024 by paulkokos

Exquisite timing is essential to many important technologies, including GPS navigation and radar. Optical approaches provide the most precise and stable timing signals, but they require bulky equipment that makes them impractical in many situations. Now, researchers at the National Institute of Standards and Technology (NIST) have created an optical…

Nvidia’s ongoing GTC developer conference in San Jose is, unsurprisingly, almost entirely about AI this year. But in between the AI developments, Nvidia has also made a couple of significant robotics announcements.First, there’s Project GR00T (with each letter and number pronounced individually so as not to invoke the wrath of…

This Transistor Can Be Reconfigured on the Fly

Computer operations are a straightforward process: Specific sets of transistors carry out predetermined logical functions. But computer researchers have hoped that someday, electronic circuits would not be stuck doing only one specific task. Instead, the idea is that circuits could be switched to perform various functions as the situation demanded—a…

Stretchy Circuits Break Records for Flexible Electronics

Newly developed intrinsically stretchable circuits are thousands of times as fast as and possess 20 times as many transistors as previous intrinsically stretchable electronics. The researchers at Stanford University who developed the circuits have already demonstrated their use in a skin-like Braille-reading sensor array that they say is more sensitive…

Nvidia Unveils Blackwell, Its Next GPU

Today at Nvidia’s developer conference, GTC 2024, the company revealed its next GPU, the B200. The B200 is capable of delivering four times the training performance, up to 30 times the inference performance, and up to 25 times better energy efficiency, compared to its predecessor, the Hopper H100 GPU. Based…

How Ultrasound Became Ultra Small

17 Μαρτίου 2024 by paulkokos

paulkokos

A startling change in medical ultrasound is working its way through hospitals and physicians’ offices. The long-standing, state-of-the-art ultrasound machine that’s pushed around on a cart, with cables and multiple probes dangling, is being wheeled aside permanently in favor of handheld probes that send images to a phone. These devices…

Laser-Driven Pacemaker Guides Ailing Hearts With Light

16 Μαρτίου 2024 by paulkokos

When 11 University of Chicago researchers reported that they had installed and tested their laser-driven pacemaker in a live animal, their Nature paper laid claim only to “the first minimally invasive optical stimulation of an in vivo pig heart.”They appear to have achieved more than that. Together, the team designed,…

How Zipline Designed Its Droid Delivery System

15 Μαρτίου 2024 by paulkokos

paulkokos

About a year ago, Zipline introduced Platform 2, an approach to precision urban drone delivery that combines a large hovering drone with a smaller package-delivery “Droid.” Lowered on a tether from the belly of its parent Zip drone, the Droid contains thrusters and sensors (plus a 2.5- to 3.5-kilogram payload)…
