علماء من جامعة كاليفورنيا في سانتا باربرا طوّروا مادة جديدة تُخزّن الطاقة الشمسية داخل جزيئات صغيرة وتطلقها لاحقًا على شكل حرارة. تعتمد التقنية على تغيّرات عكسية مستوحاة من الحمض النووي والنظارات الضوئية، ولا تحتاج إلى بطاريات ضخمة أو شبكة كهربائية. يمكن للجزيء تخزين الطاقة لسنوات ويوفر كثافة طاقة أعلى من بطاريات الليثيوم-أيون.
Scientists at UC Santa Barbara have created a remarkable new material that works like a “rechargeable solar battery,” storing sunlight inside tiny molecules and releasing it later as heat — even long after the sun goes down. Inspired by reversible changes found in DNA and photochromic sunglasses, the system captures solar energy without relying on bulky batteries or the electrical grid.
The molecule can hold energy for years and packs more energy per kilogram than lithium-ion batteries.

A groundbreaking superconducting X-ray spectrometer has begun operation at BESSY II, giving Europe its first TES-based system and boosting photon detection efficiency by up to 1,000 times. The advance enables scientists to explore atomically thin materials, nanostructures, and ultra-dilute samples with remarkable speed and sensitivity.

A new international study finds that middle-aged Americans are lonelier, more depressed, and experiencing worse memory and health than earlier generations. Researchers say growing financial strain, weaker social supports, and chronic stress may explain why the U.S. is falling behind other wealthy nations.

A groundbreaking new connectome maps every neural connection in an adult fruit fly’s central nervous system, creating an unprecedented view of how the brain and body work together. The findings suggest that complex behaviors emerge from distributed local circuits rather than a single central controller, offering new clues about intelligence, movement, and brain function.
