Alibaba Shuts Down its Quantum Computing Effort

Posted by in categories: business, quantum physics, robotics/AI

In case you missed it, China’s e-commerce giant Alibaba has shut down its quantum computing research effort. It’s not entirely clear what drove the change. Reuters’ reported earlier this week that Alibaba “cut a quantum computing laboratory and team from its research arm, donating both the lab and related experimental equipment to Zhejiang University.”

Alibaba was a relatively early entrant among giant e-commerce/cloud providers into quantum computing research, placing the effort in its Alibaba’s DAMO Academy research organization. There are reports it had invested on the order of $15 billion in the effort. According to the Reuters report, about 30 employees are being released with and effort under way to find positions for them at Zhejiang.

Rather than being tied to specific issues with the quantum research, the prevailing opinion seems to be that the quantum work was caught in the larger turmoil surrounding Alibaba and its ongoing reorganization. The company said its DAMO organization will deepen its work on AI and machining learning research which may be able to have a nearer-term impact on Alibaba’s business.

These ‘anthrobots’ created from human cells are healing neurons

Posted by in categories: biotech/medical, nanotechnology, robotics/AI

The researchers are excited by the potential of how cells cooperate and communicate in the body and how they can be reprogrammed to create new structures and functions.

With the help of Simon Garnier at the New Jersey Institute of Technology, the team characterized the different types of Anthrobots that were produced.

They observed that bots fell into a few discrete categories of shape and movement, ranging in size from 30 to 500 micrometers (from the thickness of a human hair to the point of a sharpened pencil), filling an important niche between nanotechnology and larger engineered devices.

Scientists spot oversized planet orbiting low-mass star for first time

Posted by in category: space

Researchers are perplexed by the discovery of an exoplanet with a mass that greatly surpasses what would be predicted given its closeness to the parent star.

Penn State.

Within the immense cosmic expanse, a perplexing discovery has emerged—a planet that, by all technical expectations, should not exist.

Scientists make a laser accelerator with 10 billion electron-volt beam

Posted by in categories: biotech/medical, computing

The accelerator, an advanced wakefield laser accelerator, is under 20 feet long, generating a 10 billion electron-volt (10 GeV) electron beam.

Bjorn “Manuel” Hegelich, associate professor of physics at UT and CEO of TAU Systems, alluding to the size of the chamber where the beam was produced stated: “We can now reach those energies in 10 centimeters.”

Scientists are aiming to use this technology for assessing the resilience of space-bound electronics against radiation, capturing the 3D internal configurations of emerging semiconductor chip designs, and potentially pioneering new cancer treatments and advanced medical imaging methodologies.

Researchers use 2D material to reshape 3D electronics for AI hardware

Posted by in categories: materials, robotics/AI

Multifunctional computer chips have evolved to do more with integrated sensors, processors, memory and other specialized components. However, as chips have expanded, the time required to move information between functional components has also grown.

“Think of it like building a house,” said Sang-Hoon Bae, an assistant professor of mechanical engineering and at the McKelvey School of Engineering at Washington University in St. Louis. “You build out laterally and up vertically to get more function, more room to do more specialized activities, but then you have to spend more time moving or communicating between rooms.”

To address this challenge, Bae and a team of international collaborators, including researchers from the Massachusetts Institute of Technology, Yonsei University, Inha University, Georgia Institute of Technology and the University of Notre Dame, demonstrated monolithic 3D integration of layered 2D material into novel processing hardware for artificial intelligence (AI) computing.

Hybrid phase-change memristors lead to new computing possibilities

Posted by in categories: computing, particle physics

By strategically straining materials that are as thin as a single layer of atoms, University of Rochester scientists have developed a new form of computing memory that is at once fast, dense, and low-power. The researchers outline their new hybrid resistive switches in a study published in Nature Electronics.

Developed in the lab of Stephen M. Wu, an assistant professor of electrical and and of physics, the approach marries the best qualities of two existing forms of resistive switches used for : memristors and . Both forms have been explored for their advantages over today’s most prevalent forms of memory, including dynamic random access memory (DRAM) and , but they have their drawbacks.

Wu says that memristors, which apply voltage to a thin filament between two electrodes, tend to suffer from a relative lack of reliability compared to other forms of memory. Meanwhile, phase-change materials, which involve selectively melting a material into either an amorphous state or a crystalline state, require too much power.

AI-Enhanced Imaging: Probing Brain’s Visual Processing

Posted by in categories: biotech/medical, neuroscience, robotics/AI

Summary: Researchers used AI to select and generate images for studying brain’s visual processing. Functional MRI (fMRI) recorded heightened brain activity in response to these images, surpassing control images.

The approach enabled tuning visual models to individual responses, enhancing the study of brain’s reaction to visual stimuli. This method, offering an unbiased, systematic view of visual processing, could revolutionize neuroscience and therapeutic approaches.
