Microsoft’s October 2025 Patch Tuesday fixes 183 flaws, including three exploited zero-days and two 9.9 CVSS bugs.
YouTube is currently facing a global outage, with users reporting playback errors on both the website and mobile apps.
When trying to watch videos, users see messages like “Playback error” or “Something went wrong,” while some say the site is slow or not loading at all.
The outage began within the last 30 minutes.
Muon beams can now be created in a device that is the length of a ruler.
Researchers at Berkeley Lab presented a foot-long (30 cm) compact laser-plasma accelerator (LPA) that can generate and detect highly directional muon beams. It works by using intense laser pulses to accelerate electron beams, which then create muons in significantly higher numbers and with greater directionality, providing a powerful new alternative for non-destructive imaging of large or concealed objects.
Conventional artificial muon sources are bulky and expensive, which has left many imaging applications reliant on naturally occurring, scarce, and unreliable cosmic rays. The new LPA overcomes these constraints by producing significantly higher muon yields, slashing exposure times from months to minutes, according to the study published in Physical Review Accelerators and Beams.
Geophysicists have modeled how Earth’s magnetic field could form even when its core was fully liquid. By removing the effects of viscosity in their simulation, they revealed a self-sustaining dynamo that mirrors today’s mechanism. The results illuminate Earth’s early history, life’s origins, and the magnetism of other planets. Plus, it could help forecast future changes to our planet’s protective shield.
Microsoft is investigating an ongoing incident that is preventing some customers from accessing Microsoft 365 applications.
While the company has yet to share which regions are currently affected by this ongoing issue, it has been tagged as an incident in the admin center, a designation typically used for service issues with noticeable user impact.
According to a service alert seen by BleepingComputer, Redmond is currently reviewing telemetry data to discover the root cause and develop a fix.
