Intel’s new approach to chips, details.


The new Alder Lake chips, however, are aspiring to be far more ambitious. Intel teased a full range of chips from 9W to 125W that would utilize the new hybrid approach, combining multiple high-end performance cores with efficient cores for a wider range of power when users need it and efficiency when running less strenuous tasks.

Given that Intel’s announcements today largely focused on the architectures, there are no hard product announcements, but the company did tease several planned Alder Lake SoCs that would utilize the new cores. Those include a desktop SoC with eight performance cores, eight efficiency cores, and integrated memory, graphics, and I/O; a laptop SoC with six performance cores, eight efficiency cores, imaging, Thunderbolt 4 support, memory, I/O, and more powerful Xe graphics all integrated in; and an ultramobile-focused SoC with two performance cores and eight efficiency cores.

To make all that work together, Intel also showed off its new scheduling technology, Intel Thread Director, which is designed to better handle how activity is assigned to performance or efficiency cores depending on need. For example, Thread Director can automatically assign high-priority tasks to performance cores, while offsetting background threads to efficiency cores. Intel also says that it’s collaborating with Microsoft specifically to ensure that Thread Director is optimized for “the best performance on Windows 11.”

A new project will use the electric field in an accelerator cavity to try to levitate a tiny metallic particle, allowing it to store quantum information.

Quantum computing could solve problems that are difficult for traditional computer systems. It may seem like magic. One step toward achieving quantum computing even resembles a magician’s trick: levitation. A new project at the U.S. Department of Energy’s Thomas Jefferson National Accelerator Facility will attempt this trick by levitating a microscopic particle in a superconducting radiofrequency (SRF) cavity to observe quantum phenomena.

Typically at Jefferson Lab and other particle accelerator facilities, SRF cavities enable studies of the atom.

In its first full VR news briefing, the company showed how Workrooms users can design avatar versions of themselves to meet in virtual reality conference rooms and collaborate on shared whiteboards or documents, still interacting with their own physical desk and computer keyboard.


Aug 19 (Reuters) — Facebook Inc (FB.O) on Thursday launched a test of a new virtual-reality remote work app where users of the company’s Oculus Quest 2 headsets can hold meetings as avatar versions of themselves.

The beta test of Facebook’s Horizon Workrooms app comes as many companies continue to work from home after the COVID-19 pandemic shut down physical workspaces and as a new variant is sweeping across the globe.

Facebook sees its latest launch as an early step toward building the futuristic “metaverse” that CEO Mark Zuckerberg has touted in recent weeks.

Deep below the ground, radioactive elements disintegrate water molecules, producing ingredients that can fuel subterranean life. This process, known as radiolysis, has sustained bacteria in isolated, water-filled cracks and rock pores on Earth for millions to billions of years. Now a study published in Astrobiology contends that radiolysis could have powered microbial life in the Martian subsurface.

Dust storms, cosmic rays and solar winds ravage the Red Planet’s surface. But belowground, some life might find refuge. “The environment with the best chance of habitability on Mars is the subsurface,” says Jesse Tarnas, a planetary scientist at NASA’s Jet Propulsion Laboratory and the new study’s lead author. Examining the Martian underground could help scientists learn whether life could have survived there—and the best subsurface samples available today are Martian meteorites that have crash-landed on Earth.

Tarnas and his colleagues evaluated the grain sizes, mineral makeup and radioactive element abundance in Martian meteorites and estimated the Martian crust’s porosity using satellite and rover data. They plugged these attributes into a computer model that simulated radiolysis to see how efficiently the process would have generated hydrogen gas and sulfates: chemical ingredients that can power the metabolism of underground bacteria. The researchers report that if water was present, radiolysis in the Martian subsurface could have sustained microbial communities for billions of years—and perhaps still could today.

This is interesting. 😃


A new discovery in rats shows that the brain responds differently in immersive virtual reality environments versus the real world. The finding could help scientists understand how the brain brings together sensory information from different sources to create a cohesive picture of the world around us. It could also pave the way for “virtual reality therapy” for learning and memory-related disorders ranging including ADHD, Autism, Alzheimer’s disease, epilepsy and depression.

Mayank Mehta, PhD, is the head of W. M. Keck Center for Neurophysics and a professor in the departments of physics, neurology, and electrical and computer engineering at UCLA. His laboratory studies a brain region called the hippocampus, which is a primary driver of learning and memory, including spatial navigation. To understand its role in learning and memory, the hippocampus has been extensively studied in rats as they perform spatial navigation tasks.
