Distant galaxy protocluster harbors a remarkably evolved core, observations find

Using the James Webb Space Telescope (JWST), an international team of astronomers has performed deep and high spectral resolution imaging of a distant protocluster of galaxies, designated A2744-z7p9OD. Results of the new observations, published July 8 on the arXiv preprint server, shed more light on the properties of this protocluster, revealing that it hosts a remarkably evolved core.

Galaxy clusters are collections of hundreds to thousands of galaxies bound together by gravity. Such clusters are the most immense gravitationally bound structures in the universe, and therefore they could serve as excellent laboratories for studying galaxy evolution and cosmology.

Of special interest for astronomers are studies of protoclusters of galaxies—the progenitors of clusters. These objects, found at high redshifts (over 2.0), could provide essential information about the early phases of the universe.

World Record Achieved in Transmission Capacity and Distance: With 19-core Optical Fiber with Standard Cladding Diameter 1,808 km Transmission of 1.02 Petabits per Second

An international research team led by the Photonic Network Laboratory at the National Institute of Information and Communications Technology (NICT, President: TOKUDA Hideyuki Ph.D.), and including Sumitomo Electric Industries, Ltd. (Sumitomo Electric, President: INOUE Osamu) have set a new world record in optical fiber communications, achieving data transmission at 1.02 petabits per second over a distance of 1,808 kilometers (roughly equivalent to the distance from Sapporo to Fukuoka, from Missouri to Montana or from Berlin to Naples).

Mixture-of-Recursions: Learning Dynamic Recursive Depths for Adaptive Token-Level Computation

View recent discussion. Abstract: Scaling language models unlocks impressive capabilities, but the accompanying computational and memory demands make both training and deployment expensive. Existing efficiency efforts typically target either parameter sharing or adaptive computation, leaving open the question of how to attain both simultaneously. We introduce Mixture-of-Recursions (MoR), a unified framework that combines the two axes of efficiency inside a single Recursive Transformer. MoR reuses a shared stack of layers across recursion steps to achieve parameter efficiency, while lightweight routers enable adaptive token-level thinking by dynamically assigning different recursion depths to individual tokens.

New ultra-secure SSD can self-destruct to protect sensitive data

This message will self-destruct in 3… 2… 1 is something you’ve definitely seen in Mission: Impossible films over the years.

Now, we finally have tech that feels just as futuristic, thanks to a new kind of storage hardware.

Taiwanese company TeamGroup has unveiled a new internal SSD that can literally destroy itself at the press of a button, ensuring sensitive data never falls into the wrong hands.

The device, called the P250Q-M80, is aimed at sectors where top-tier data security isn’t just a perk, it’s a necessity. We’re talking defense, industrial automation, AI development, and maybe even the crypto wallet you hold.

TeamGroup showcased the drive at Computex 2025, where it took home a Best Choice Award in the cybersecurity category.
