Four distinct variants of Alzheimer’s identified in brain imaging study


A new international study has found four distinct patterns of toxic protein spread in the brains of patients with Alzheimer’s disease. The findings indicate these patterns correspond with particular symptoms, and the researchers hypothesize these four variants could respond to different treatments.

The research focused the accumulation and spread of a toxic protein in the brain called tau. Alongside amyloid beta, another protein known to be implicated in neurodegeneration, the spread of tau has been associated with cognitive decline seen in Alzheimer’s.

Wood burners: Sale of coal and wet wood restricted in England



Curbs on the sale of house coal and wet wood for household burning in England have come into force under new rules aimed at cutting air pollution.

People will still be able to use stoves and open fires but they will need to burn cleaner alternatives.

These are the first restrictions on what people can burn in their homes since the clean air acts of the 1950s.

When Autonomous Cars Teach Themselves to Drive Better Than Humans


A few weeks ago, the CTO of Cruise Tweeted an example of one of their AVs demonstrating a safety behavior where it moves over to make room for a cyclist. What’s interesting about this behavior, though, is that the AV does this for cyclists approaching rapidly from behind the vehicle, something a human is far less likely to notice, much less react to. A neat trick—but what does it mean, and what’s next?

IBM's new 2-nm chips have transistors smaller than a strand of DNA


In a shining example of the inexorable march of technology, IBM has unveiled new semiconductor chips with the smallest transistors ever made. The new 2-nanometer (nm) tech allows the company to cram a staggering 50 billion transistors onto a chip the size of a fingernail.

The current industry standard is chips with 7-nm transistors, with some high-end consumer devices, such as Apple’s M1 processors, beginning to make the move to 5 nm. And experimental chips have shrunk as small as 2.5 nm.

‘It’s like the embers in a barbecue pit.’ Nuclear reactions are smoldering again at Chernobyl


Thirty-five years after the Chernobyl Nuclear Power Plant in Ukraine exploded in the world’s worst nuclear accident, fission reactions are smoldering again in uranium fuel masses buried deep inside a mangled reactor hall. “It’s like the embers in a barbecue pit,” says Neil Hyatt, a nuclear materials chemist at the University of Sheffield. Now, Ukrainian scientists are scrambling to determine whether the reactions will wink out on their own—or require extraordinary interventions to avert another accident.

Linux Foundation launches open source agriculture infrastructure project


The Linux Foundation has lifted the lid on a new open source digital infrastructure project aimed at the agriculture industry. The AgStack Foundation, as the new project will be known, is designed to foster collaboration among all key stakeholders in the global agriculture space, spanning private business, governments, and academia.

As with just about every other industry in recent years, there has been a growing digital transformation across the agriculture sector that has ushered in new connected devices for farmers and myriad AI and automated tools to optimize crop growth and circumvent critical obstacles, such as labor shortages.

Electric cars ‘will be cheaper to produce than fossil fuel vehicles by 2027’

Electric cars and vans will be cheaper to produce than conventional, fossil fuel-powered vehicles by 2027, and tighter emissions regulations could put them in pole position to dominate all new car sales by the middle of the next decade, research has found.

By 2026, larger vehicles such as electric sedans and SUVs will be as cheap to produce as petrol and diesel models, according to forecasts from BloombergNEF, with small cars reaching the threshold the following year.
