Solar Storms Drive ISS Astronauts to Take Cover Amid Auroras
Intro: Solar storms, auroras, and the ISS When the Sun unleashes a surge of charged particles, the effects ripple across the solar system. In recent days, intense solar storms have lit up skies around the world with dazzling auroras. Meanwhile, aboard the International Space Station, crew members had to implement precautionary measures to shield against…

Solar Storms Ignite Auroras: ISS Astronauts Take Cover and Watch
Stunning skies, serious risks Across the globe, vibrant auroras have lit up night skies as solar storms interact with Earth’s magnetosphere. While the spectacle captivates amateur stargazers and professional scientists alike, the same solar activity that paints the heavens with color also raises radiation levels in space. For astronauts aboard the International Space Station (ISS),…

Impact of tube voltage on image quality and radiation dose in CT coronary angiography: a comparative study of 100 vs 120 kVp protocols
Introduction In CT coronary angiography (CTCA), balancing image quality with patient safety is essential. This observational study from Kasturba Hospital, Manipal, investigates how tube voltage—specifically 100 kVp versus 120 kVp—affects image quality and radiation exposure. By tailoring voltage to body mass index (BMI), researchers aim to achieve diagnostic-quality images while minimizing radiation dose. Study design…
