Google’s new Willow quantum processor has reignited discussions around blockchain security and their ability to withstand rapid advancements.

A team of Rice University scientists has solved a long-standing problem in thermal imaging, making it possible to capture clear images of objects through hot windows. Imaging applications in a range of fields—such as security, surveillance, industrial research and diagnostics—could benefit from the research findings, which were reported in the journal Communications Engineering.

“Say you want to use thermal imaging to monitor chemical reactions in a high-temperature reactor chamber,” said Gururaj Naik, an associate professor of electrical and computer engineering at Rice and corresponding author on the study. “The problem you’d be facing is that the thermal radiation emitted by the window itself overwhelms the camera, obscuring the view of objects on the other side.”

A possible solution could involve coating the window in a material that suppresses thermal light emission toward the camera, but this would also render the window opaque. To get around this issue, the researchers developed a coating that relies on an engineered asymmetry to filter out the thermal noise of a hot window, doubling the contrast of thermal imaging compared to conventional methods.

A vulnerability in WPForms, a WordPress plugin used in over 6 million websites, could allow subscriber-level users to issue arbitrary Stripe refunds or cancel subscriptions.

Tracked under CVE-2024–11205, the flaw was categorized as a high-severity problem due to the authentication prerequisite. However, given that membership systems are available on most sites, exploitation may be fairly easy in most cases.

The issue impacts WPForms from version 1.8.4 and up to 1.9.2.1, with a patch pushed in version 1.9.2.2, released last month.

Conversely, proprietary LLMs typically offer robust security features but still pose data privacy and control risks. Using these models involves sharing sensitive data with a third-party provider, which could lead to regulatory penalties if a breach occurs.

LLMs also lack transparency regarding their training data and how datasets are formed. Be mindful of potential bias and fairness issues and consider a human-in-the-loop approach, where specialists review and manage the model’s output.

LLMs are most effective when used to streamline complex processes and drive innovation. To leverage these models responsibly, prioritize data governance—especially in highly regulated industries.

Kaunas University of Technology (KTU), Lithuania researchers, and scientists from Japan have developed a unique nanolaser. Although the dimensions of this laser are so small that its structure can only be seen through a powerful microscope, its potential is vast. With applications in early medical diagnostics, data communication, and security technologies, this invention could also become a key tool for the study of light and matter interactions.

Depending on the application, lasers differ in the way light is amplified and produced, which determines the color of the radiation and the quality of the laser beam.

“Nanolasers are lasers that use structures a million times smaller than a millimeter to generate and amplify light, and the laser radiation is generated in an extremely tiny volume of material,” says Dr. Mindaugas Juodėnas, one of the authors of the invention.

South Australia has the highest wind and solar share – an average of around 72 per cent over the last 12 months – vastly more than other state in Australia, and higher than any other gigawatt scale grid in the world.

Renewable energy critics, particularly those that don’t understand the way that grids work, instantly assume that this means South Australia’s grid must be weak and unreliable. But that is simply not true, and a new report from Australian Energy Market Operator on “system strength” underlines why this is so.

System strength is an important part of grid security, and – according to AEMO – describes the ability of the power system to maintain and control the voltage waveform at a given location, when the grid is running normally and particularly when it has to deal with a major disturbance.

Critical flaws in MLflow, PyTorch, and more enable remote code execution, threatening AI and ML security.

In today’s world, the fight against counterfeiting is more critical than ever. Counterfeiting affects about 3% of global trade, posing significant risks to the economy and public safety. From fake pharmaceuticals to counterfeit currency, the need for secure and reliable authentication methods is paramount. Authentication labels are commonly used—such as holograms on bank notes and passports—but there is always a need for new unfalsifiable technologies.

This is where research recently published in Applied Sciences comes into play. Led by a team of scientists from Oxford University, the University of Southampton, and Diamond Light Source, the UK’s national synchrotron, the work focuses on developing a new technology for writing and reading covert information on authentication labels.

This technology leverages the unique properties of Ge₂Sb₂Te₅ thin films, which can change their structure when exposed to specific types of laser light. By using circularly or linearly polarized laser light, the researchers can encode hidden information in these thin films. This information can then be revealed using a simple reading device, making the technology both advanced and accessible.

Researchers have developed an innovative optical technology capable of enhancing data transmission by utilizing spatial-frequency patching metasurfaces.

This approach allows light beams to carry significantly more data across multiple independent channels, overcoming traditional optical beam limitations. Its applications extend to secure communication, encryption, and advanced optical systems.

Revolutionary optical technology for data transmission.

“This work shows that sensitive information can be leaked in ways that previously haven’t been considered,” said Poorya Mollahosseini, a graduate student at Princeton and the paper’s co-lead author with Sayed Saad Afzal, a graduate student at MIT.

How are underwater communications protected?

The security of underwater communications relies heavily on the inability of sound traveling underwater to penetrate the surface, the researchers said. Signals that carry information are transmitted underwater as sound waves. Because water and air have very different densities, the water’s surface acts as a barrier for sound. When underwater sound waves hit the surface, they mostly just bounce off.
