علماء اكتشفوا عالمًا بحريًّا مخفيًّا في الأخاديد العميقة قبالة ساحل غرب أستراليا، باستخدام تحليل الحمض النووي من مياه الأعماق التي تجاوزت ٤ كيلومترات. وشمل الاكتشاف دلائل على وجود حبار عملاق وأكثر من ٢٢٦ نوعًا بحريًّا، بعضها نادر أو غير معروف علميًّا. يُعد هذا التقدم دليلاً على فعالية تقنيات التحليل البيئي للحمض النووي في استكشاف التنوع البيولوجي المغمور.
Scientists exploring deep underwater canyons off the coast of Western Australia uncovered a hidden world packed with bizarre and elusive marine life — including signs of the legendary giant squid. By analyzing traces of DNA floating in seawater from depths exceeding 4 kilometers, researchers identified 226 species ranging from deep-diving whales to strange fish rarely or never seen in the region before.
Some of the creatures may even be unknown to science.

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.
