Smarter memory: Researchers introduce next-generation RAM with reduced energy consumption

Posted by in category: computing

Numerous memory types for computing devices have emerged in recent years, aiming to overcome the limitations imposed by traditional random access memory (RAM). Magnetoresistive RAM (MRAM) is one such memory type which offers several advantages over conventional RAM, including its non-volatility, high speed, increased storage capacity and enhanced endurance.

Although remarkable improvements have been made to MRAM devices, reducing energy consumption during data writing remains a critical challenge.

A study published in Advanced Science by researchers from Osaka University proposes a new technology for MRAM devices with lower-energy data writing. The proposed technology enables an -based writing scheme with reduced energy consumption compared to the present current-based approach, potentially providing an alternative to traditional RAM.

Fabricating single-photon detectors from superconducting aluminum nanostrips

Posted by in categories: computing, quantum physics

In quantum computers, information is often carried by single photons and picked up by structures named superconducting nanostrip single-photon detectors (SNSPDs). In principle, traditional type-I superconductors would be easier to integrate into existing quantum computing architectures than the type-II materials more widely used today. So far, however, this possibility hasn’t been widely explored.

New research published in Superconductivity shows how Lixing You and colleagues at the Chinese Academy of Sciences, Shanghai, China have for the first time successfully fabricated an SNSPD using thin films of the type-I superconductor, , and used the structure to detect single photons of visible light with extremely high efficiency.

Compared with the type-II superconductors more commonly used in SNSPDs so far, aluminum is more compatible with the latest quantum computing architectures.

Posted by in categories: finance, information science, mathematics, robotics/AI, supercomputing

A breakthrough in artificial intelligence.

Artificial Intelligence (AI) is a branch of computer science focused on creating systems that can perform tasks typically requiring human intelligence. These tasks include understanding natural language, recognizing patterns, solving problems, and learning from experience. AI technologies use algorithms and massive amounts of data to train models that can make decisions, automate processes, and improve over time through machine learning. The applications of AI are diverse, impacting fields such as healthcare, finance, automotive, and entertainment, fundamentally changing the way we interact with technology.

New EAGERBEE Variant Targets ISPs and Governments with Advanced Backdoor Capabilities

Posted by in categories: cybercrime/malcode, evolution, internet

Internet service providers (ISPs) and governmental entities in the Middle East have been targeted using an updated variant of the EAGERBEE malware framework.

The new variant of EAGERBEE (aka Thumtais) comes fitted with various components that allow the backdoor to deploy additional payloads, enumerate file systems, and execute commands shells, demonstrating a significant evolution.

“The key plugins can be categorized in terms of their functionality into the following groups: Plugin Orchestrator, File System Manipulation, Remote Access Manager, Process Exploration, Network Connection Listing, and Service Management,” Kaspersky researchers Saurabh Sharma and Vasily Berdnikov said in an analysis.
