The smaller transistors get, the more expensive they get, and similarly, the harder it becomes for foundries to compete at the cutting edge. We’ve been seeing this since the introduction of TSMC and Samsung’s 7nm node (comparable to Intel’s 10nm process). Global Foundries was the first to drop out of the race, and Intel has been stuck on its 14nm node for nearly seven years (although the chipmaker is trying to make a comeback). Samsung is the third major foundry struggling to keep up with TSMC in the race to make the smallest transistors.

Samsung’s 10nm and 7nm nodes were both on par with TSMC’s, at least in terms of transistor density, packing 0.52 and 0.95 million transistors per square mm. Meanwhile, Intel’s 10nm node was denser than both, with a density of 1.06 million per square mm. Starting with the 5nm node, Samsung’s nodes have fallen behind. The Korean foundry’s 5nm node has a transistor density of 1.27 million (per mm2), compared to 1.73 million on TSMC’s 5nm and 1.8 million on Intel’s 7nm.

The deltas become even wider with the 3nm node, with Samsung expected to offer a density of just 1.7 million, compared to 2.9 million on TSMC’s 3nm (despite not using GAA), and 3 million on Intel’s 3nm. Samsung has continued to lose foundry customers, with both Qualcomm and MediaTek shifting to TSMC due to poor supply. It’s being reported that NVIDIA too will rely on TSMC’s 5nm for its next-gen GPUs, resulting in the loss of another major client for the former. At this rate, Samsung might just throw in the towel even before its 3nm node begins mass production.

Engineers at the University of California San Diego developed a new wearable device that turns the touch of a finger into a source of power for small electronics and sensors. The device is a thin, flexible strip worn on a fingertip and generates small amounts of electricity when a person’s finger sweats or presses on it.

More interestingly, this sweat-powered device is capable of generating power even when the wearer is asleep or sitting still. This could open up some very interesting possibilities in the wearable space, as the researchers have now figured out how to harness the energy that can be extracted from human sweat even when a person is not moving.

Google is reportedly working on a foldable Pixel phone that will feature an ultra thin glass layer on top of the foldable display.

Scientists have been turning to the animal world for inspiration for a long time, including for medicines. And many different types of animals have been responsible for this inspiration, including sharks, spiders, and… roadkill.

The annual meteor shower peaks on July 29.

The annual Delta Aquariids meteor shower kicks off from July 12 to August 23 each year, peaking on July 29.

An acoustic tractor beam that can bend sound around an obstacle to levitate an object on the other side has been created by researchers in the UK. Dubbed SoundBender, the device combines an ultrasound transducer array with an acoustic metamaterial.

In recent years, researchers have used transducer arrays to build sonic tractor beams that can create complex acoustic holograms to manipulate objects in mid-air. Acoustic metamaterials are engineered materials with structural properties that do not usually occur naturally. They have been used to produce acoustic holograms, bend beams of sound and create static acoustic levitation devices. But the team behind the SoundBender, based at the University of Sussex, say that these technologies have key limitations.

In a medical first, researchers harnessed the brain waves of a paralyzed man unable to speak — and turned what he intended to say into sentences on a computer screen.

It will take years of additional research but the study, reported Wednesday, marks an important step toward one day restoring more natural communication for people who can’t talk because of injury or illness.

“Most of us take for granted how easily we communicate through speech,” said Dr. Edward Chang, a neurosurgeon at the University of California, San Francisco, who led the work. “It’s exciting to think we’re at the very beginning of a new chapter, a new field” to ease the devastation of patients who lost that ability.

Two options for error correction both work, but current hardware limits them.

Today the U.S. Patent and Trademark Office officially granted Apple a patent that relates to an integrated photonics device. Apple is working with a UK Photonics company that supplies specialized components for the smartwatch market. One medical network publication believes that Apple is working with this UK company on a blood glucose solution.
