Study highlights the vulnerabilities of metasurface-based wireless communication systems

Posted by in categories: cybercrime/malcode, internet

Metasurfaces, artificially engineered surfaces that can manipulate electromagnetic signals in unique ways, have huge potential for several technological applications, including the implementation of sixth generation (6G) cellular communications. The limitations and vulnerabilities of these smart surfaces, however, are still poorly understood.

Researchers at Peking University, University of Sannio and Southeast University recently carried out a study aimed at better understanding the vulnerability of metasurfaces to wireless cyber-attacks. Their paper, published in Nature Electronics, outlines two types of attacks that should be considered and accounted for before metasurfaces can be deployed on a large-scale.

“This work was primarily driven by the need for enhancing security and privacy of in the upcoming 6G era, characterized by unprecedented speeds, ultra-low latency, and vast connection nodes,” Lianlin Li, Vincenzo Galdi and Tie Jun Cui, three of the researchers who carried out the study, told Tech Xplore.

You can now train ChatGPT on your own documents via API

Posted by in categories: internet, robotics/AI

On Tuesday, OpenAI announced fine-tuning for GPT-3.5 Turbo—the AI model that powers the free version of ChatGPT—through its API. It allows training the model with custom data, such as company documents or project documentation. OpenAI claims that a fine-tuned model can perform as well as GPT-4 with lower cost in certain scenarios.

So basically, fine-tuning teaches GPT-3.5 Turbo about custom content, such as project documentation or any other written reference. That can come in handy if you want to build an AI assistant based on GPT-3.5 that is intimately familiar with your product or service but lacks knowledge of it in its training data (which, as a reminder, was scraped off the web before September 2021).

Quantum And The Ultimate Weapon Inside The SBOM

Posted by in categories: cybercrime/malcode, encryption, government, internet, law enforcement, quantum physics

• Encryption and segmentation: These operate on the assumption some fraction of the network is already compromised. Restricting the reach and utility of any captured data and accessible networks will mitigate the damage even on breached systems.

• SBOM documentation: Regulatory compliance can be driven by industry organizations and the government, but it will take time to establish standards. SBOM documentation is an essential foundation for best practices.

If “democracy dies in darkness,” and that includes lies of omission in reporting, then cybersecurity suffers the same fate with backdoors. The corollary is “don’t roll your own crypto” even if well-intentioned. The arguments for weakening encryption to make law enforcement easier falls demonstrably flat, with TETRA just the latest example. Secrets rarely stay that way forever, and sensitive data is more remotely accessible than at any time in history. Privacy and global security affect us all, and the existence of these single points of failure in our cybersecurity efforts are unsustainable and will have unforeseeable consequences. We need to innovate and evolve the internet away from this model to have durable security assurances.

SpaceX Reportedly Achieved Profitability In The First Quarter Of 2023

Posted by in categories: Elon Musk, finance, internet, satellites

SpaceX, led by Elon Musk, has reportedly achievedability in the first quarter of 2023, marking a significant milestone for the privately owned rocket company. According to the Wall Street Journal (WSJ), SpaceX reported a of $55 million on $1.5 billion in revenue for the January-to-March period. This success comes after two years of narrowing losses, with the company managing to cut its 2022 losses to $559 million from the previous year’s $968 million while doubling its revenue to $4.6 billion.

The positive financial results reflect SpaceX’s growing revenue, driven in part by its Starlink internet satellite service and the development of its ambitious Starship rocket. The company’s surging revenue has enabled it to make progress towardability while pursuing its ambitious goals in space exploration and satellite communication.

The WSJ report also sheds light on SpaceX’s significant expenses, with the company recording total expenses of $5.2 billion in 2022, up from $3.3 billion in the previous year. Despite these costs, SpaceX’sability in the first quarter signals the potential for its ongoing success as it continues to innovate and expand its operations in the space industry.

Study shows potential for generative AI to increase access and efficiency in healthcare

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

A new study led by investigators from Mass General Brigham has found that ChatGPT was about 72 percent accurate in overall clinical decision making, from coming up with possible diagnoses to making final diagnoses and care management decisions. The large-language model (LLM) artificial intelligence chatbot performed equally well in both primary care and emergency settings across all medical specialties. The research team’s results are published in the Journal of Medical Internet Research.

Our paper comprehensively assesses decision support via ChatGPT from the very beginning of working with a patient through the entire care scenario, from differential diagnosis all the way through testing, diagnosis, and management. No real benchmarks exists, but we estimate this performance to be at the level of someone who has just graduated from medical school, such as an intern or resident. This tells us that LLMs in general have the potential to be an augmenting tool for the practice of medicine and support clinical decision making with impressive accuracy.

Google Secretly Showing Newspapers an AI-Powered News Generator

Posted by in categories: internet, robotics/AI

Google is secretly showing off an AI tool that can produce news stories to major newspapers, including The New York Times, The Washington Post, and The Wall Street Journal.

The tool, dubbed Genesis, can digest public information and generate news content, according to reporting by the New York Times, in yet another sign that AI-generated — or at least AI-facilitated — content is about to flood the internet.

Google is stridently denying that the tool is meant to replace journalists, saying it will instead serve as a “kind of personal assistant for journalists, automating some tasks to free up time for others.”

Advances in quantum emitters mark progress toward a quantum internet

Posted by in categories: computing, internet, quantum physics, security

The prospect of a quantum internet, connecting quantum computers and capable of highly secure data transmission, is enticing, but making it poses a formidable challenge. Transporting quantum information requires working with individual photons rather than the light sources used in conventional fiber optic networks.

To produce and manipulate , scientists are turning to quantum light emitters, also known as . These atomic-scale defects in semiconductor materials can emit single photons of fixed wavelength or color and allow photons to interact with electron spin properties in controlled ways.

A team of researchers has recently demonstrated a more effective technique for creating quantum emitters using pulsed ion beams, deepening our understanding of how are formed. The work was led by Department of Energy Lawrence Berkeley National Laboratory (Berkeley Lab) researchers Thomas Schenkel, Liang Tan, and Boubacar Kanté who is also an associate professor of electrical engineering and computer sciences at the University of California, Berkeley.
