IISc, startup develop magnetic nanobots to treat tooth sensitivity

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.

She worked at Harvard for 30 cents an hour, her work shaped our understanding of the universe, but never won a Nobel Prize

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.

Deepest ancient water found: Scientist discovers and tastes 2 billion-year-old groundwater

Scientists discovered the oldest water on Earth, dating back billions of years, in a Canadian mine. This ancient water, isolated for millennia, provides unprecedented insights into Earth's early conditions and potential for life in extreme environments. Professor Barbara Sherwood Lollar's team's findings challenge existing assumptions and open new avenues for astrobiological research.
