The latest generations of Intel processors, including Xeon chips, and AMD’s older microarchitectures on Linux are vulnerable to new speculative execution attacks that bypass existing ‘Spectre’ mitigations.

The vulnerabilities impact Intel’s 12th, 13th, and 14th chip generations for consumers and the 5th and 6th generation of Xeon processors for servers, along with AMD’s Zen 1, Zen 1+, and Zen 2 processors.

Active electronics — components that can control electrical signals — usually contain semiconductor devices that receive, store, and process information.

Researchers produced 3D-printed, semiconductor-free logic gates, which perform computations in active electronic devices. As they don’t require semiconductor materials, they represent a step toward 3D printing an entire active electronic device.

Trees are the most abundant natural resource living on Earth’s land masses, and North Carolina State University scientists and engineers are making headway in finding ways to use them as sustainable, environmentally benign alternatives to producing industrial chemicals from petroleum.

Lignin, a polymer that makes trees rigid and resistant to degradation, has proven problematic. Now those NC State researchers know why: They’ve identified the specific molecular property of lignin — its methoxy content — that determines just how hard, or easy, it would be to use microbial fermentation to turn trees and other plants into industrial chemicals.

Amazon is using a new, proprietary AI solution called Vision-Assisted Package Retrieval (VAPR) to reduce the time and effort it takes for delivery drivers to locate packages in their vans. Is it a game-changer, or more AI VAPR-ware?

Somewhat lost in the hype surrounding the Tesla “We, Robot” event on 10/10 was an AI press release from Amazon that promises to improve the lives of the people who use it today, rather than two years from now.

Arctech Solar says it has signed a 2.3 GW tracker order from Saudi Arabia, where it will supply trackers designed for the region’s desert terrain and high winds.

Instead of needing constant power, new system adjusts to use whatever’s available.

A short pulse of voltage rebuilds lost capacity in lithium-silicon batteries, but may not work with others.

With liquid biopsies, detecting cancer and tracking treatment progress can be as easy as taking a blood test. This is an increasingly popular way of monitoring cancer, because it’s much less invasive than solid tumour biopsies. And liquid biopsies can become even more sensitive if they capture methylation information as well as genetic data.

Usually, liquid biopsies for cancer rely on the detection of small amounts of DNA that are shed from a tumour into the bloodstream. But especially in the disease’s early stages, circulating tumour DNA (ctDNA) levels are very low and point mutations linked to cancer can be easy to miss.

“If we want to develop assays to detect cancer earlier, we need very sensitive detection of these rare tumour fragments,” says Charlotte Proudhon, group leader at the Research Institute for Environmental and Occupational Health in Rennes, France, whose team are among those now developing liquid biopsy methods that include epigenetic markers, such as methylation.

A new University of Maryland-led discovery could spur the development of new and improved treatments for Hutchinson-Gilford progeria syndrome (HGPS), often simply called “progeria”—a rare genetic disorder with no known cure that causes accelerated aging in children.

Researchers identify protein that could improve cardiovascular health of those with progeria.
