Hidden stem cells may be fueling spinal stenosis

Scientists have discovered a stem cell that appears to serve as a master source for tendon and ligament cells throughout the body. In lumbar spinal stenosis, these cells become unusually active and may drive the ligament overgrowth that squeezes spinal nerves and causes pain, numbness, and difficulty walking. Researchers found that reducing calcium signaling stopped this abnormal growth in mice.

SpaceX wants to launch 100,000 Starlink satellites to orbit

SpaceX is nothing if not ambitious. Elon Musk 's company just filed an application with the U.S. Federal Communications Commission (FCC) to operate a 100,000-member constellation of "Gen3" satellites in low Earth orbit (LEO). This will presumably be an updated version of SpaceX's Starlink broadband network, according to astronomer and satellite tracker Jonathan McDowell, who reported the news via X today (July 9). SpaceX have filed for a 100,00 satellite "Gen3 NGSO" system. Presumably Starlink Gen3, but they don't call it that. The sats are 2000-2500 kg, area 300 to 400 sq m. Orbits 320-480 km at various inclinations. Have added to my page at https://t.co/uFI9aoSNnM July 9, 2026 The new plan would dramatically expand Starlink's already extensive orbital footprint. SpaceX currently operates nearly 10,800 of the internet spacecraft in LEO and has FCC approva...
