Ukraine’s Computer Emergency Response Team (CERT) says that Russian hackers are exploiting CVE-2026–21509, a recently patched vulnerability in multiple versions of Microsoft Office.
On January 26, Microsoft released an emergency out-of-band security update marking CVE-2026–21509 as an actively exploited zero-day flaw.
CERT-UA detected the distribution of malicious DOC files exploiting the flaw, themed around EU COREPER consultations in Ukraine, just three days after Microsoft’s alert.
Euan Ashley’s lab explores the intricate interactions of gene variants. Tiny “typos,” or genetic mutations, can sneak into segments of DNA. Many of these are harmless, but some can cause health problems. Two or more genes can team up and change the outcome of a physical or molecular trait. This phenomenon, known as epistasis, occurs through complex interactions between genes that are functionally related—such as those that support protein creation.
Identifying these group dynamics provides crucial clues to how genetic diseases manifest and should be treated. But they’re not easily detected and often fly under the radar.
To help root out these connections, Ashley, MB ChB, DPhil, professor of genetics and of biomedical data science, and a team of scientists, including co-corresponding author Bin Yu, Ph.D., a professor of statistics and of electrical engineering and computer sciences at the University of California, Berkeley, have developed computational techniques to identify and understand the hidden ways epistasis influences inherited diseases.
Milan, 13th January 2025 — The Politecnico di Milano has created the first integrated and fully tunable device based on spin waves, opening up new possibilities for the telecommunications of the future, far beyond current 5G and 6G standards. The study, published in the journal Advanced Materials, was conducted by a research group led by Riccardo Bertacco of the Department of Physics of the Politecnico di Milano, in collaboration with Philipp Pirro of Rheinland-Pfälzische Technische Universität and Silvia Tacchi of Istituto Officina dei Materiali — CNR-IOM.
Magnonics is an emerging technology that uses spin waves – collective excitations of electronic spins in magnetic materials – as an alternative to electrical signals. The spread of this technology has been restricted until now by the need for an external magnetic field, which has prevented it being incorporated into chips.
The new device developed at the Politecnico overcomes this hurdle: it is miniaturised (100 × 150 square micrometres, so much smaller than current radiofrequency signal processing devices based on acoustic waves); it is fully integrated on silicon – and therefore compatible with existing electronic platforms, and it functions without external magnets, thanks to an innovative combination of permanent SmCo micromagnets and magnetic flux concentrators.
Quantum smartphone chip.
IDQ’s QRNG chip is available in six models, depending on size, performance, power consumption and certifications, in order to fit various industry-specific needs. All IDQ QRNG chips have received NIST Entropy Source Validation (ESV) certification on the independently and identically distributed (IID) entropy estimation track SP 800-90B.
ID Quantique is the first company to achieve an ESV certificate with a quantum entropy source and IID estimation track. Such randomness provides the most trusted random keys for encryption. Since October 2022 it has been mandatory for cryptographic modules aiming for FIPS 140–3 certification to have an ESV validated entropy source. This ESV IID Certificate #63 will also facilitate IDQ’s customers who integrate IDQ’s Chips into their own devices to go through the NIST’s Cryptographic Module Validation Program (CMVP).
Blood vessels are less like straight pipes and more like a crowded city road map, with turns, forks, and sudden choke points that can change how traffic moves. For a long time, many lab built vessel models skipped that complexity and relied on simple, straight channels, even though real vessels rarely behave that neatly.
Researchers in the Department of Biomedical Engineering at Texas A&M University are trying to close that gap with a customizable vessel-chip method. The goal is to recreate the kinds of shapes that matter in disease, so experiments on blood flow and potential treatments reflect what happens in the body more closely and can better support drug discovery.
Vessel-chips are engineered microfluidic devices that mimic human vasculature on a microscopic scale. Instead of studying blood flow in animals or oversimplified lab setups, scientists can use these chips to examine how fluid forces move through vessel-like structures in a controlled environment. Because the design can be tailored, the platform can also support patient-focused studies, which is especially useful when small differences in anatomy may affect how disease develops or how a therapy performs.
A team of researchers from the University of Stuttgart and the Julius-Maximilians-Universität Würzburg led by Prof. Stefanie Barz (University of Stuttgart) has demonstrated a source of single photons that combines on-demand operation with record-high photon quality in the telecommunications C-band—a key step toward scalable photonic quantum computation and quantum communication. “The lack of a high-quality on-demand C-band photon source has been a major problem in quantum optics laboratories for over a decade—our new technology now removes this obstacle,” says Prof. Stefanie Barz.
In everyday life, distinguishing features may often be desirable. Few want to be exactly like everyone else. When it comes to quantum technologies, however, complete indistinguishability is the name of the game. Quantum particles such as photons that are identical in all their properties can interfere with each other—much as in noise-canceling headphones, where sound waves that are precisely inverted copies of the incoming noise cancel out the background.
When identical photons are made to act in synchrony, then the probability that certain measurement outcomes occur can be either boosted or decreased. Such quantum effects give rise to powerful new phenomena that lie at the heart of emerging technologies such as quantum computing and quantum networking. For these technologies to become feasible, high-quality interference between photons is essential.
Research on the perception of color differences is helping resolve a century-old understanding of color developed by Erwin Schrödinger. Los Alamos scientist Roxana Bujack led a team that used geometry to mathematically define the perception of color as it relates to hue, saturation and lightness.
Presented at the 2025 Eurographics Conference on Visualization, their work formalizes Schrödinger’s model of color, decisively establishing the perception of color attributes as an intrinsic property. The paper, “The Geometry of Color in the Light of a Non-Riemannian Space,” was published in the Computer Graphics Forum.
“What we conclude is that these color qualities don’t emerge from additional external constructs such as cultural or learned experiences but reflect the intrinsic properties of the color metric itself,” Bujack said. “This metric geometrically encodes the perceived color distance—that is, how different two colors appear to an observer.”
