When blockchains first appeared nearly a decade ago as the technical backbone of Bitcoin, the world’s leading cryptocurrency, they seemed to offer the masses a way to cut out the financial middleman. But now the big banks and other industry players are finding ways to spin the new tool to their advantage.

Inside the Universe Machine: The Webb Space Telescope’s Trailblazing Optics

As NASA’s newest Big Science project opens its eyes, IEEESpectrum reflects on JWST’s groundbreaking engineering

The James Webb Space Telescope’s 18-segment gold mirror enables it to see a penny 40 kilometers away, or a football 550 kilometers away.

“Build something that will absolutely, positively work.” This was the mandate from NASA for designing and building the James Webb Space Telescope—at 6.5 meters wide the largest space telescope in history. Last December, JWST launched famously and successfully to its observing station out beyond the moon. And now according to NASA, as soon as next week, the JWST will at long last begin releasing scientific images and data.

Mark Kahan, on JWST’s product integrity team, recalls NASA’s engineering challenge as a call to arms for a worldwide team of thousands that set out to create one of the most ambitious scientific instruments in human history. Kahan—chief electro-optical systems engineer at Mountain View, Calif.–based Synopsys—and many others in JWST’s “pit crew” (as he calls the team) drew hard lessons from three decades ago, having helped repair another world-class space telescope with a debilitating case of flawed optics. Of course the Hubble Space Telescope is in low Earth orbit, and so a special space-shuttle mission to install corrective optics ( as happened in 1993) was entirely possible.

Shoppers are seeing more and more empty shelves, as stores around the world struggle to keep products stocked. The situation is the result of supply-chain issues caused in part by the COVID-19 pandemic. The product-unavailability rate increased from 5 percent to 15 percent during the past three years, according to the Consumer Brands Association.

To make it easier for stores to track inventory, startup Wisy developed an AI platform that uses image recognition to detect which products are out of stock or running low, as well as those that are available but haven’t yet been put on display.

As 5G evolves into 6G networks, it will be critical that it adopt the most energy-efficient technologies to reduce carbon emissions and our dependence on non-renewable resources.

In terms of increased sustainability, 6G will need to aim directly at lessening its overall environmental impact, including water consumption, raw material sourcing, and waste handling. But it is also important to consider the indirect impact of 6G networks can have on sustainability by conserving resources and minimizing waste in either existing use-cases or novel use-cases.
