علماء اكتشفوا أن محيط التيثيس المفقود ربما شكل جبال آسيا الوسطى خلال العصر الديناصوري. واعتمدوا في ذلك على بيانات جيولوجية تم جمعها على مدى عقود، وأظهرت أن النشاط التكتوني المرتبط بهذا المحيط القديم تزامن مع فترات تكوّن جبلي سريع. ويُعد هذا الاكتشاف ثورة محتملة في فهم عمليات تشكيل الجبال عالميًا.
Scientists have uncovered evidence that the vanished Tethys Ocean may have sculpted Central Asia’s mountainous landscape during the dinosaur era. Using decades of geological data, researchers found that distant tectonic activity linked to the ancient ocean appears to match periods of rapid mountain formation. Surprisingly, climate and mantle processes played only a minor role.
The discovery could reshape how scientists understand mountain building across the planet.

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.
