Emotional experience evokes signalling in astrocytes, which form an ensemble that is reinforced by secondary astrocytic state changes resulting from repeated experience, leading to memory stabilization.

Electrostatic repulsion between electrons usually impairs the performance of electron microscopes. Now it can be turned into an advantage.

A new spectroscopy method outperforms its rivals by pairing an ordinary frequency comb with an entangled one.

Geologic clues reveal a hidden link between two major faults. A Cascadia quake might set the San Andreas in motion soon after. When the tectonic subduction zone beneath the Pacific Northwest shifts, it does so violently. A magnitude 9+ earthquake in this region would unleash powerful ground shaki

CISA adds Adobe AEM CVE-2025–54253 to its KEV list after confirmed active exploitation.

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.
