باحثون يقترحون أن الراهب الإنجليزي إيلمر من مالمزبري قد اكتشف أن مذنب هالي يعود دورياً قبل إدموند هالي بـ700 عام، بعد أن رصده في 989 و1066. كانت المذنبات تُعتبر آنذاك علامات نحس مرتبطة بالحروب والوفيات الملكية، ما زاد من دلالة ظهورها في سجادة بايو. هذا الاكتشاف يعيد فتح نقاش حول تسمية المذنب.
A medieval monk may have beaten Edmond Halley to one of astronomy’s greatest discoveries by nearly 700 years. Researchers say Eilmer of Malmesbury recognized that the blazing comet seen in 1066 was the same one he had witnessed in 989. At the time, comets were viewed as terrifying omens tied to war and royal deaths, adding even more drama to the famous celestial event shown in the Bayeux Tapestry.
The discovery is sparking debate over whether Halley’s Comet deserves a different name.

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.
