Pulsars may be revealing that extremely low-frequency gravitational waves are moving through the universe. Observations reported in 2023 by international pulsar timing array collaborations could be caused by either a background of overlapping gravitational waves from countless distant sources or a single pair of nearby supermassive black holes orbiting each other. To determine which explanation…
What do you do when you encounter a strange astronomical event, a collection of data from planets thousands of light-years away, and models that can’t quite explain what you’re seeing? For one astronomer at Northern Arizona University’s Department of Astronomy and Planetary Science, the answer is simple: start building better models. With funding from the…
Lyndsey TelfordBBC News NI BBC Health minister Mike Nesbitt said he was determined to get the plan out ahead of last years plan, which was published in November. The health minister has defended his department’s timeline for initiating a plan to deal with winter pressures on the health service. Mike Nesbitt said a plan has…
It rains on the Sun, and scientists at the University of Hawaiʻi Institute for Astronomy (IfA) have finally uncovered the reason why. Unlike the water that falls from clouds on Earth, solar rain takes place in the Sun’s corona, the outermost layer made of intensely hot plasma. This phenomenon involves cooler, heavier blobs of plasma…
Security has always been about controlling who can do what and where. In 2025, that control is mediated entirely by identity. When an attacker “logs in,” not “breaks in”, they inherit legitimate permissions, blend into normal telemetry, and pivot across AD, Entra/Okta, SaaS, and cloud, driving multi-million-dollar losses. Credentials, tokens, and service accounts have become…
Nature follows countless rhythms: the changing of the seasons comes from Earth’s orbit around the Sun, and the steady tick of a clock arises from the back-and-forth swing of its pendulum. These patterns can be described with simple mathematical laws. Yet, order can also appear in a far more surprising way — on its own,…
A new randomized, placebo-controlled clinical trial suggests that a single round of low-dose radiation therapy could offer a safe and effective alternative for people suffering from painful knee osteoarthritis. Participants with mild to moderate knee osteoarthritis experienced notable pain reduction and improved mobility within four months of receiving the treatment. The radiation exposure was only…
By Reuters Published October 15, 2025 Italy, whose sovereign assets from bonds to banks have so often been the subject of market crises in recent years, is currently enjoying a windfall as the central bank’s vast gold reserves track record-high prices. A secure room inside the Bank of Italy’s gold vault is filled with stacked…
CISOs and security leaders today face extraordinary challenges: the constant influx of vast quantities of fragmented threat data, information that lacks the context necessary for their unique organizations, and mounting operational gaps that hinder genuine risk reduction. The need has shifted from “more visibility” to “more insight.” To sift through the noise and move faster…
“If you don’t include people with disabilities or people with facial differences in the development of these processes, no one’s going to think of these issues,” says Kathleen Bogart, a psychology professor at Oregon State University who specializes in disability research and lives with a facial difference. “AI has amplified these issues, but it’s rooted…
