Researchers reveal a process called mitochondrial pearling, where mitochondria transiently form bead-like constrictions to split and redistribute mitochondrial DNA nucleoids along their length, maintaining even spacing. This calcium-triggered, membrane-supported mechanism helps preserve mtDNA organization and could shed light on metabolic and neurodegenerative diseases, with findings published in Science.
Johns Hopkins researchers report axons may be pearl-like strings rather than smooth tubes, a pattern seen in mouse, worm, and human neurons and persisting in normal tissue. The beads are about 250 nm with 70 nm connectors, influenced by membrane stiffness and cholesterol, and can speed or slow signal transmission. This challenges a century of textbook axon structure and is supported by advanced imaging and living-brain tissue studies, suggesting membrane physics plays a key role in brain signaling.
Archeologists in the UAE have discovered what they believe to be the oldest pearling town in the Persian Gulf, predating Islamic civilization. The town, located on Sinniyah Island, is believed to have housed thousands of residents and operated year-round. The community's houses were built from local beach rocks and materials from the surrounding environment, and their roofs were made of palm trunks. The settlement is particularly unique due to its age, size, and year-round operation. The town is believed to have been home to Christian residents and was likely a key industry for the region.
Archaeologists have discovered the oldest pearling town in the Persian Gulf on Siniyah Island in Umm al-Quwain, UAE, dating back to the late 6th century. The town, likely home to thousands of people and hundreds of homes, predates the rise of Islam and was likely inhabited by Christians. The site includes a variety of homes made of beach rock and lime mortar, loose pearls, and diving weights. The discovery sheds light on the history of pearling in the region and the industrial waste it produced. The UAE plans to build a visitor's center at the site.
Archaeologists have discovered the oldest pearling town in the Persian Gulf on Siniyah Island in Umm al-Quwain, UAE. The town dates back to the late 6th century and is likely to have been home to thousands of people and hundreds of homes. The site bears signs of year-round habitation, unlike other pearling operations run in seasonal spots in the region. The town predates the rise of Islam across the Arabian Peninsula, making its residents likely Christians. The discovery holds particular importance in the history of the UAE as it faces a looming reckoning with its fossil fuel legacy and potentially plans for a carbon-neutral future.
