A new optical phenomenon has been demonstrated by an international team of scientists led by physicists at the University of Bath, with significant potential impact on pharmaceutical science, security, forensics, environmental science, art conservation and medicine.
The plan would be to launch Starship from a SpaceX facility in Texas, land it in the sea off Australia’s coast and recover it on Australian territory. Getting permission to do so would require loosening US export controls on sophisticated space technologies bound for Australia, according to the sources, who spoke on condition of anonymity.
President Joe Biden’s administration already has sought to ease similar restrictions within the AUKUS security alliance, opens new tab, a grouping of the United States, Australia and Britain aimed at countering China.
SpaceX, the US Space Force and the Australian Space Agency did not immediately reply to requests for comment.
Shiver me timbers: Security researchers have demonstrated that it’s possible to spy on what’s visible on your screen by intercepting electromagnetic radiation from video cables with great accuracy, thanks to artificial intelligence. The team from Uruguay’s University of the Republic says their AI-powered cable-tapping method is good enough that these attacks are likely already happening.
Back in the analog video era, it was relatively straightforward for hackers to reconstruct what was on a screen by detecting the leakage from video cables. But once digital protocols like HDMI took over, that became much trickier. The data zipping through HDMI is much more complex than old analog signals.
However, those digital signals still leak some electromagnetic radiation as they transmit between your computer and display. By training an AI model on samples of matching original and intercepted HDMI signals, the researchers were able to decode those leaks into readable screen captures.
In an era where the internet connects virtually every aspect of our lives, the security of information systems has become paramount. Safeguarding critical databases containing private and commercial information presents a formidable challenge, driving researchers to explore advanced encryption techniques for enhanced protection.
Data encryption, a cornerstone of modern security practices, transforms readable plaintext into encoded ciphertext, ensuring that only authorized recipients can decipher the data using a decryption key or password. Optical techniques have emerged as promising tools for encryption due to their capabilities for parallel, high-speed transmission, and low-power consumption. However, traditional optical encryption systems often suffer from vulnerabilities where plaintext-ciphertext forms remain identical, potentially compromising security.
Reporting in Advanced Photonics Nexus, scientists have unveiled an approach inspired by bio-inspired neuromorphic imaging and speckle correlography. Their innovative technique leverages computational neuromorphic imaging (CNI) to encrypt images into event-stream ciphertexts, marking a significant departure from conventional methods. This method introduces a new paradigm in optical encryption by converting data into event-driven formats, thereby significantly enhancing security and complexity.
Infleqtion, the world’s leading quantum information company, announced the installation of a cutting-edge neutral atom quantum computer at the National Quantum Computing Centre (NQCC).
PRESS RELEASE — Infleqtion, the world’s leading quantum information company, is proud to announce the installation of a cutting-edge neutral atom quantum computer at the National Quantum Computing Centre (NQCC). This marks a significant milestone as Infleqtion becomes the first company to deploy hardware at the NQCC under their quantum computing testbed programme. The news comes on the heels of Infleqtion’s rapid advancement in quantum gate fidelity.

The semiconductor industry has grown into a $500 billion global market over the last 60 years. However, it is grappling with dual challenges: a profound shortage of new chips and a surge of counterfeit chips, introducing substantial risks of malfunction and unwanted surveillance. In particular, the latter inadvertently gives rise to a $75 billion counterfeit chip market that jeopardizes safety and security across multiple sectors dependent on semiconductor technologies, such as aviation, communications, quantum, artificial intelligence, and personal finance.
The range of threats, they say, include “attackers exploit[ing] this vulnerability to gain unauthorized access, execute arbitrary code, and cause substantial damage without any user interaction. The absence of authentication requirements makes it particularly dangerous, as it opens the door to widespread exploitation.”
The repeated reference to “trusted senders” in this warning is important. This vulnerability only carries a zero click threat when an email is received from a trusted source. If the sender is unknown, then the user would need to click to execute. That said, if the problem for an attacker is now spoofing emails from trusted sources that’s a very low bar in today’s world of industrial scale business email compromise.
Researchers have developed a novel method for generating structured terahertz light beams using programmable spintronic emitters. This breakthrough offers a significant leap forward in terahertz technology, enabling the generation and manipulation of light with both spin and orbital angular momentum at these frequencies for the first time.
Terahertz radiation lies between microwaves and infrared light on the electromagnetic spectrum. It holds great promise for various applications, including security scanners, medical imaging, and ultrafast communication. However, generating and controlling terahertz light effectively has proven challenging.
This new research, published in eLight and led by Prof. Zhensheng Tao, Prof. Yizheng Wu from Fudan University and Prof. Yan Zhang from Capital Normal University, overcomes these limitations by employing programmable spintronic emitters based on exchange-biased magnetic multilayers. These devices consist of thin layers of magnetic and non-magnetic materials that convert laser-induced spin-polarized currents into broadband terahertz radiation.
The power of quantum computing drives a desperate need for quantum encryption. This megatrend is creating a multi-billion-dollar security market.
Engineers at the University of California, Los Angeles (UCLA) have unveiled a major advancement in optical computing technology that promises to enhance data processing and encryption. The work is published in the journal Laser & Photonics Reviews.
This innovative work, led by Professor Aydogan Ozcan and his team, showcases a reconfigurable diffractive optical network capable of executing high-dimensional permutation operations, offering a significant leap forward in telecommunications and data security applications.
Permutation operations, essential for various applications, including telecommunications and encryption, have traditionally relied on electronic hardware. However, the UCLA team’s advancement uses all-optical diffractive computing to perform these operations in a multiplexed manner, significantly improving efficiency and scalability.
