اكتشف علماء مستويات غير متوقعة من ملوثات سيليكونية تُعرف باسم الميثيل سيلوكسانات في الغلاف الجوي، حتى في المناطق النائية مثل الغابات. ويعود جزء كبير منها إلى انبعاثات المركبات، خصوصًا من إضافات زيت المحرك التي تنجو من الاحتراق. وتشير التقديرات إلى أن الإنسان قد يستنشق كميات أكبر من هذه المركبات يوميًا مقارنةً بملوثات أخرى معروفة مثل البلاستيك الدقيق أو مركبات الـPFAS.
Researchers have uncovered unexpectedly high levels of silicone-based pollutants called methylsiloxanes floating through the atmosphere across cities, rural regions, and even forests. Much of the pollution appears to come from vehicle emissions, likely linked to engine oil additives that survive combustion and escape into the air.
Scientists say humans may inhale more of these compounds daily than other notorious pollutants like PFAS or microplastics.

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.
