Japón no necesitaba otro portaaviones para mover ficha. Su siguiente paso militar empieza con Vietnam

Japón se ha pasado décadas midiendo cada gesto militar con una cautela casi quirúrgica. No por falta de industria, tecnología o capacidad, sino por el peso de su historia reciente y por los límites políticos que han marcado su defensa desde la posguerra. Por eso, cuando Tokio mueve una pieza en este terreno, conviene mirar más allá del tamaño aparente del gesto. Lo que tenemos delante muestra hacia dónde se mueve el país asiático. La noticia concreta. El movimiento aparece en un comunicado del Ministerio de Defensa japonés después de la reunión que el ministro de Defensa Shinjiro Koizumi…

NVIDIA ha encontrado una forma de contener el consumo de los centros de datos de IA: líquido más caliente que un jacuzzi

Durante años, hemos asociado los centros de datos eficientes con salas frías, pasillos de aire helado y máquinas rugiendo para mantener los servidores bajo control. La expansión de la inteligencia artificial está obligando a revisar esa imagen. La próxima generación de infraestructura no solo tiene que alojar chips más potentes, también debe mantenerlos funcionando sin que el consumo energético crezca al mismo ritmo. En ese escenario, NVIDIA apuesta por una solución contraintuitiva : usar un refrigerante a 45°C , una temperatura más alta que la de muchos jacuzzis. El motivo de este cambio…

A Korean AI model scores every possible driving path for safety before the car moves. CVPR called it a highlight.

Most self-driving AI models study how humans drive and try to copy them. They work well in normal conditions but struggle to explain why they chose one path over another, which becomes a problem when a split-second decision goes wrong. A team at Seoul National University led by professor Jun Won Choi has built a […] This story continues at The Next Web

Alzheimer’s breakthrough: Scientists restore two hours of sleep without clearing brain plaques

Researchers have uncovered a surprising culprit behind sleep loss in Alzheimer’s disease: the brain’s own immune cells. In mice with amyloid plaques, overactive microglia triggered inflammation that kept the brain from getting enough deep, restorative sleep. Temporarily removing most of these cells restored more than two hours of sleep per day, even though the plaques remained unchanged.

Scientists discover a protein that protects the brain from Alzheimer’s damage

A protein called SORLA may act as a powerful defense against the toxic tau tangles involved in Alzheimer’s disease. Mice with extra SORLA had less tau accumulation, less brain atrophy, and healthier connections between neurons, while mice without it experienced more severe damage. The findings also revealed a possible drug target that could help control harmful activity in supporting brain cells.

Scientists detect hidden skin damage before it becomes visible

Scientists have discovered a hidden warning sign of skin damage that appears before collagen fibers visibly thin, break, or lose their connections. Using advanced light-based techniques, the team found that collagen’s carefully organized molecular “handedness” can collapse even while the tissue still appears structurally intact and contains the same amount of collagen. This suggests that skin may begin deteriorating at a much deeper level long before conventional imaging can detect a problem.
