Nanotechnology was once the stuff of science fiction, but today the concept of creating devices and machines that are several thousand times smaller than the width of a human hair is a well-established fact. The rise of nanotechnology has already transformed industries ranging from consumer electronics to textile manufacturing and cosmetics by unlocking new materials and processes at the nanoscale. The device you’re reading this on, for example, is only possible because of techniques adopted in the semiconductor industry that enable us to pattern silicon and metals to create the microscopic circuits and switches that are at the heart of modern computers.

One of the most promising applications of our newfound ability to manipulate individual atoms and molecules is in healthcare, where the ability of doctors to treat disease has been hamstrung by relatively blunt “macro” solutions. The human body is a remarkably complex system where, fundamentally, nanoscale processes occurring inside cells are what determine whether we are sick or healthy. If we’re ever going to cure diseases like diabetes, cancer or Alzheimer’s, we need technologies that work at their scale. Although medical nanotechnologies are relatively new, they’re already impacting the way we diagnose, treat and prevent a broad range of diseases.

The July issue of Scientific American magazine has a terrific review of the Voyager space mission that details the trips Voyagers 1 and 2 have made through the Solar System. The article is titled “Record-Breaking Voyager Spacecraft Begin to Power Down.” Both spacecraft have now entered interstellar space and are the first human artifacts to do so. Tim Folger wrote the article for Scientific American. Towards the end of the article, Folger points out that Voyagers 1 and 2 were designed before the advent of the microprocessor and that the mission has lasted 44 years, so far, which is about 40 years longer than the planned design life for the spacecraft.

The article then quotes Stamatios Krimigis, a PhD physicist and space scientist who’s spent more than half a century at the Johns Hopkins Applied Physics Laboratory. Krimigis says, “The amount of software on these instruments is slim to none. On the whole, I think the mission lasted so long because almost everything was hardwired. Today’s engineers don’t know how to do this. I don’t know if it’s even possible to build such a simple spacecraft [now]. Voyager is the last of its kind.”

Open-source code runs on every computer on the planet—and keeps America’s critical infrastructure going. DARPA is worried about how well it can be trusted.

Physicists demonstrated a way of storing quantum information that is less prone to errors by subjecting a quantum computer’s qubits to quasi-rhythmic laser pulses based on the Fibonacci sequence.

Physicists have created a remarkable, never-before-seen phase of matter by shining a laser pulse sequence inspired by the Fibonacci sequence at atoms inside a quantum computer. Despite there still being only one singular flow of time, the phase has the benefits of two time dimensions, the physicists reported on July 20 in the journal Nature.

This mind-bending property offers a highly desirable benefit: Information stored in the phase is far more protected against errors than with alternative setups currently used in quantum computers. As a result, the information can exist for far longer without getting garbled, an important milestone for making quantum computing.

Intel’s Raptor Lake CPU has been benchmarked in Geekbench, and the results are quite impressive.

A research partnership between Penn State and the Massachusetts Institute of Technology (MIT) could enable an improved method to make a new type of semiconductor that is a few atoms thin and interacts with light in an unusual way. This new semiconductor could lead to new computing and communications technologies that use lower amounts of energy than current electronics.

The new type of semiconductor, tin selenide (SnSe), would be useful for developing a new type of electronics known as “photonics” that use particles of light, or photons, to store, manipulate and transmit information. Traditional electronics use electrons to do this, while photonics use photons. Tin selenide is a binary compound consisting of tin and selenium in a 1:1 ratio.

The material has a peculiar interaction with light that gives it great potential for use in electronics.

China’s dependence on foreign suppliers of computer chips could undermine the country’s transition to electric vehicles, tech traders and researchers say.

The shortage of chips, or semiconductors, is more acute in China than elsewhere and could hit the nation’s EV momentum, according to CATARC, the China Automotive Technology and Research Center, because its fledgling domestic chipmaking industry is unlikely to be in a position to cope with demand within the next two to three years, it says.

With delivery delays of up to a year, that means carmakers in China are occasionally being forced to pay expensive premiums to chip brokers in cities like Shenzhen, where there is a “grey market” trade in semiconductors.

France is set to welcome a new semiconductor production site on its soil as it continues the drive to position itself on the global market amid growing shortages, though it is still unclear where funding for the new plant is coming from.

France will open a new semiconductor factory, according to the announcement by French company STMicroelectronics and US company GlobalFoundries released on Monday (11 July).
