Henrietta Swan Leavitt worked as a Harvard “computer” earning just 30 cents an hour, yet her groundbreaking discovery of the period-luminosity relationship transformed astronomy. Her work enabled scientists to measure cosmic distances and understand the expanding universe. Despite this monumental contribution, Leavitt never received a Nobel Prize during her lifetime, highlighting the challenges faced by women in science.
Researchers at IISc and Theranautilus create 'CalBots'. These magnetic nanobots address tooth sensitivity. CalBots seal dentinal tubules using a bioceramic formula. Tests on extracted teeth show promising results. Animal trials demonstrate complete behavioral recovery. The team sees this as a step towards advanced nanorobotics. This innovation offers lasting relief for millions. The CalBots are made from safe materials.
NASA has shared new details about 3I/ATLAS. It is an interstellar object moving at 209,000 km/h. Hubble images show it is smaller than thought, about 5.6 km wide. It is a comet with a glowing tail. Scientists estimate it is eight billion years old. It poses no threat to Earth. NASA uses telescopes to study it.
Blue Origin now accepts cryptocurrency, including Bitcoin and Ethereum, for its New Shepard space tourism flights, partnering with Shift4 Payments for secure transactions. This move allows customers to book flights with digital currencies, requiring a $150,000 deposit. The initiative aims to broaden accessibility and integrate crypto into the luxury space travel market, offering an 11-minute suborbital experience.
A groundbreaking study unveils 117-million-year-old mud waves beneath the Atlantic, reshaping our understanding of its formation. These massive structures, sculpted by ancient underwater avalanches, indicate the Atlantic Ocean connected earlier than previously thought. This discovery provides insights into Cretaceous climate shifts and tectonic movements, offering crucial data for modern geology and climate science.
NASA and Google are collaborating on an AI medical assistant. It is called Crew Medical Officer Digital Assistant or CMO-DA. This tool will help astronauts during long space missions. It will provide autonomous medical support. Testing shows high accuracy in diagnosing common issues. Future updates will integrate medical device data.
