Kyoto University researchers have used orbital data from 1,200 Starlink satellites to map thermospheric density at 482 km. By analyzing atmospheric drag via tomography, the team created a 2D density map, offering a new method for monitoring the upper atmosphere.
Kyoto University researchers have developed a method to map thermospheric density at 482 km altitude by analyzing orbital drag data from 1,200 Starlink satellites, offering a new way to monitor the upper atmosphere using existing commercial infrastructure.
Scientists have named a newly described non-venomous snake species from New Guinea Lielaphis slashi after Guns N' Roses guitarist Slash, honoring his lifelong interest in reptiles and natural history.
Vallabh Ramesh, an 18-year-old high school student, has created a thermo-responsive polymer gel that can be 3D-printed with affordable equipment, changing properties at body temperature, with potential applications in drug delivery, tissue engineering, and beyond.
A study in Puglia, Italy, found that installing photovoltaic panels over vineyards increased grape yields by 277% compared to full-sun vines. The system improved microclimate conditions, soil moisture, and energy generation, achieving a land equivalent ratio of 3.54.
A new study identifies stone tools at Jebel Katefeh 1 in Saudi Arabia's Nefud Desert as likely Neanderthal, suggesting the hominin group migrated deeper into the Arabian Peninsula than previously known around 55,000 years ago during a wetter climate period.
