The UK military is jamming satellites belonging to other nations as a defensive measure, according to information given to the BBC. The disclosure sheds light on Britain's electronic warfare capabilities in orbit, an area governments rarely discuss publicly. The report has drawn attention to growing competition and defensive operations in space among major military powers.

Nvidia has added LG Electronics to its Partner Network as a preferred cooling provider, aiming to ease the power and heat constraints of its AI data centre systems. The alliance gives LG a direct route to supply thermal management technology, as attention shifts from GPUs to the cooling infrastructure needed to run them.

Analysis of Russia's Geran-4 attack drone shows it is built around a roughly $25,000 hobby jet engine and relies on Texas Instruments microchips, despite Western sanctions meant to cut Russia off from advanced electronics. The findings highlight how cheap consumer and off-the-shelf components continue to power Russian weapons used in the war against Ukraine.

Researchers report that hyperbolic wave attractors, structures that trap and concentrate light waves, could be used to build next-generation optical chips. By confining light more efficiently, the approach may improve photonic circuits used in computing and communications. Details of the research and its practical applications remain limited in the available reporting.
