A team led by Professor Fang Lu from the Department of Electrical Engineering at Tsinghua University has announced the development of the world’s first sub-angstrom resolution spectral imaging chip, dubbed ” Yuheng .” The research, published in the journal Nature under the title “Integrated lithium niobate photonics sub-angstrom snapshot spectral imaging” , represents a significant advance in smart photonics technology. Despite its compact dimensions of just 2 cm × 2 cm × 0.5 cm, the chip offers a spectral resolution of R = 12,000 , allowing for the acquisition of a full spectrum for each pixel. This capability eliminates traditional limitations that

An untrusted data deserialization vulnerability has been identified in the Apache ActiveMQ NMS AMQP client, exposing systems to potential attacks from malicious servers. The flaw, tracked as CVE-2025-54539, has a score of 9.8 out of 10, and affects all versions up to and including 2.3.0 when connections are established to untrusted AMQP servers. According to security experts at Endor Labs , who reported the flaw, a suitably modified remote server can exploit the client’s unconstrained deserialization logic to send manipulated responses, potentially allowing arbitrary code execution on the victim’s system. A security mechanism based on allow/deny lists was already introduced in version

In early October 2025, Microsoft stopped a large malicious operation attributed to the Vanilla Tempest group, revoking more than 200 digital certificates used to fraudulently sign Microsoft Teams installation files. These fake packages served as a vector to spread the Oyster backdoor and, later, the Rhysida ransomware . The discovery and countermeasures The campaign was discovered in late September 2025 , after months of activity in which the threat actor had exploited seemingly legitimate binaries. In response, Microsoft Defender Antivirus has updated its signatures to recognize and block both fake Teams installers and the malware involved, while Microsoft Defender for Endpoint has

Jen-Hsun Huang, founder and CEO of Nvidia, revealed that recent export restrictions have drastically reduced the presence of the company’s AI chips in China , from 95% to virtually nothing. “Four years ago, Nvidia had a 95% market share in China. Today, it’s only 50%,” Huang said in May 2025, denouncing the increasing restrictions imposed since the Joe Biden era. But today everything has changed and China has started producing AI chips for itself. Huang’s remarks on October 17 highlight the current consequences of these limitations on the global dynamics of artificial intelligence. Despite restrictions on the purchase of advanced chips, China

A North Korean group linked to the DPRK has developed EtherHiding , a method for hiding malicious code within public blockchain smart contracts and modifying payloads on the fly. According to Google Threat Intelligence Group, this technique was adopted by the UNC5342 group, also known as CL-STA-0240 from Palo Alto Networks, DeceptiveDevelopment from ESET, and DEVPOPPER from Securonix. The attack vectors are consistent with the long-running “Contagious Interview” campaign: attackers contact developers via LinkedIn, posing as recruiters, move the conversation to Telegram or Discord, and, under the guise of a test, trick them into executing malicious code. The goal is to gain

A consortium of Nvidia, Microsoft, BlackRock and xAI , the company founded by Elon Musk , announced on Wednesday an agreement to acquire Aligned Data Centers for a total value of $40 billion . Aligned, which specializes in the design and management of data centers and technology campuses in North and South America , is currently controlled by Macquarie Asset Management . According to the companies involved, the transaction will be led by MGX , an Abu Dhabi -based company and member of BlackRock’s Global Infrastructure Partners and AI Infrastructure Partners (AIP) . The agreement involves the acquisition of 100% of Aligned

South Korea has launched a repatriation operation for its citizens from Cambodia, following reports of kidnappings, violence and the death of a 22-year-old student who was the victim of a large-scale scam. According to South Korea’s Directorate for National Security, Wi Seungrak, the location of most of the missing has been identified, but 79 remain unaccounted for. About 60 other citizens have been arrested by Cambodian authorities, and the government plans to secure their repatriation. Fraud centers in Cambodia function like closed labor camps: people are lured with advertisements promising high wages, then held in closed premises and forced to defraud others

In the UK, father and son Jason and Luke Stoner have transformed an old school bus into a traveling museum dedicated to retro computers and game consoles. The inspiration came when Luke visited the famous Computer Museum in Cambridge, deciding to make vintage technology accessible to a wider audience. Thus was born Retro Reset, a nonprofit organization that began the complete restoration of the vehicle in autumn 2024. The project was completed in just a year, with the Cambridge Museum among the initiative’s main sponsors. The bus currently travels across East Sussex, stopping at schools, colleges and youth centres, aiming to introduce

Once upon a time, a degree in computer science was a guarantee of success. Competitive salaries, generous benefits, and immediate employment opportunities were the norm. Today, however, for many young graduates in 2025, the reality has turned out to be very different. Azka Azmi, a recent spring graduate, told the Toronto Star she’s sent out hundreds of applications without a single response. “It’s like talking to a machine,” she explained, describing an increasingly impersonal and frustrating selection process. Statistics confirm this trend. In Ontario, job opportunities in software development and programming decreased by 25% between 2020 and 2024. Entry-level positions—traditionally the first

On October 15, in addition to the much-vaunted NVIDIA DGX Spark solution, created in collaboration between NVIDIA and Mediatek, another mini AI accelerator made its debut to the world: the GIGABYTE ATOM. GIGABYTE Technology, today announced the official launch of its AI TOP ATOM , a platform based on the NVIDIA Grace Blackwell GB10 superchip, the same chip as the DGX Spark. This innovative solution features a lightweight design compatible with standard home power supplies and comes pre-installed with the NVIDIA AI software stack, delivering powerful compute performance, making it an ideal platform for AI prototyping, tuning, and inference. The AI TOP
