Researchers at Tohoku University and the University of California, Santa Barbara, have developed new computing hardware that utilizes a Gaussian probabilistic bit made from a stochastic spintronics device. This innovation is expected to provide an energy-efficient platform for power-hungry generative AI.

As Moore’s Law slows down, domain-specific hardware architectures—such as probabilistic computing with naturally stochastic building blocks—are gaining prominence for addressing computationally hard problems. Similar to how quantum computers are suited for problems rooted in , probabilistic computers are designed to handle inherently probabilistic algorithms.

These algorithms have applications in areas like combinatorial optimization and statistical machine learning. Notably, the 2024 Nobel Prize in Physics was awarded to John Hopfield and Geoffrey Hinton for their groundbreaking work in machine learning.

Scientists have used a pair of lasers and a supersonic sheet of gas to accelerate electrons to high energies in less than a foot. The development marks a major step forward in laser-plasma acceleration, a promising method for making compact, high-energy particle accelerators that could have applications in particle physics, medicine, and materials science.

In a new study soon to be published in the journal Physical Review Letters, a team of researchers successfully accelerated high-quality beams of electrons to more than 10 billion electronvolts (10 gigaelectronvolts, or GeV) in 30 centimeters. The preprint can be found in the online repository arXiv.

The work was led by the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab), with collaborators at the University of Maryland. The research took place at the Berkeley Lab Laser Accelerator Center (BELLA), which set a world record of 8-GeV electrons in 20 centimeters in 2019. The new experiment not only increases the , but also produces high-quality beam at this energy level for the first time, paving the way for future high-efficiency machines.

The sun, the essential engine that sustains life on Earth, generates its tremendous energy through the process of nuclear fusion. At the same time, it releases a continuous stream of neutrinos—particles that serve as messengers of its internal dynamics. Although modern neutrino detectors unveil the sun’s present behavior, significant questions linger about its stability over periods of millions of years—a timeframe that spans human evolution and significant climate changes.

Finding answers to this is the goal of the LORandite EXperiment (LOREX) that requires a precise knowledge of the solar neutrino cross section on thallium. This information has now been provided by an international collaboration of scientists using the unique facilities at GSI/FAIR’s Experimental Storage Ring ESR in Darmstadt to obtain an essential measurement that will help to understand the long-term stability of the sun. The results of the measurements have been published in the journal Physical Review Letters.

LOREX is the only long-time geochemical solar neutrino experiment still actively pursued. Proposed in the 1980s, it aims to measure solar neutrino flux averaged over a remarkable four million years, corresponding to the geological age of the lorandite ore.

Three distinct topological degrees of freedom are used to define all topological spin textures based on out-of-plane and in-plane spin configurations: the topological charge, representing the number of times the magnetization vector m wraps around the unit sphere; the vorticity, which quantifies the angular integration of the magnetic moment along the circumferential direction of a domain wall; and the helicity, defining the swirling direction of in-plane magnetization.

Electrical manipulation of these three degrees of freedom has garnered significant attention due to their potential applications in future spintronic devices. Among these, the helicity of a magnetic skyrmion—a critical topological property—is typically determined by the Dzyaloshinskii-Moriya interaction (DMI). However, controlling skyrmion helicity remains a formidable challenge.

A team of scientists led by Professor Yan Zhou from The Chinese University of Hong Kong, Shenzhen, and Professor Senfu Zhang from Lanzhou University successfully demonstrated a controllable helicity switching of skyrmions using spin-orbit torque, enhanced by thermal effects.

For those unaware, Whisk3D (original name Blendersito) is Dante’s Symbian-powered version of Blender, which he has been developing since late 2022. The app allows users to upload and model 3D characters on the phone, design game level assets, extrude vertices and edges, create planes, and even connect the phone to a monitor and keyboard for more convenient use.

In a true Blender fashion, Dante’s Whisk3D is open-source and can be accessed via the creator’s GitHub page. You can also support Dante here and check out more jaw-dropping experiments with Nokia-ran Blender over here.

“The chain of exploitation underscores the importance of securing every component of a WordPress site, especially third‑party themes and plugins, which can become critical points of entry for attackers.”

The development comes as Wordfence disclosed a high-severity flaw in the WPForms plugin (CVE-2024–11205, CVSS score: 8.5) that makes it possible for authenticated attackers, with Subscriber-level access and above, to refund Stripe payments and cancel subscriptions.

The vulnerability, which affects versions 1.8.4 up to, and including, 1.9.2.1, has been resolved in versions 1.9.2.2 or later. The plugin is installed on over 6 million WordPress sites.

Secret Blizzard has a track record of targeting various sectors to facilitate long-term covert access for intelligence collection, but their primary focus is on ministries of foreign affairs, embassies, government offices, defense departments, and defense-related companies across the world.

The latest report comes a week after the tech giant, along with Lumen Technologies Black Lotus Labs, revealed Turla’s hijacking of 33 command-and-control (C2) servers of a Pakistan-based hacking group named Storm-0156 to carry out its own operations.

The attacks targeting Ukrainian entities entail commandeering Amadey bots to deploy a backdoor known as Tavdig, which is then used to install an updated version of Kazuar, which was documented by Palo Alto Networks Unit 42 in November 2023.

Recent research from the S: CORT team has identified key biomarkers and treatment strategies that predict and enhance effectiveness of radiotherapy in rectal cancer treatment.

Patients with advanced rectal cancer often receive radiotherapy before surgery. However, despite this being standard practice, this treatment only results in complete disappearance (complete response) prior to surgery in 15% of patients.

Currently, there are no reliable biomarkers (a biological molecule found in blood, other , or tissues that is a sign of a normal or abnormal process, or of a condition or disease) to predict which colorectal patients will benefit from radiotherapy, meaning that many patients are unnecessarily exposed to significant side effects.
