Radiation is a form of energy released in the form of rays, particles, or waves. It can be found all around us, from the sun and stars, to man-made sources like cell phones, computers, and nuclear power plants. Radiation can be both beneficial and harmful. It can be used to diagnose and treat illnesses and diseases, or it can cause long-term health problems such as cancer. On this page, you can find the latest news, articles, and videos about radiation and how it affects us.
In 2021, a coronal mass ejection that erupted from the sun was seen across a staggering range of 155 million miles. It spit energetic particles toward Mars, the Earth and the moon.
Scientists have detected the sun emitting an extraordinary amount of gamma rays — light wavelengths known to carry the most energy of any other wavelength in the electromagnetic spectrum.
Stars serve as the fundamental building blocks of galaxies and, by extension, the entire observable universe. Among the diverse spectrum of stars, those with a mass exceeding 8 times that of the Sun are labeled as massive stars. Their potent radiation and formidable stellar winds exert a significant
New fossil ape from Türkiye rewrites the story of human origins. Anadoluvius lived nearly 9 million years ago and is ancestral to living African apes and humans, according to an international team led by University of Toronto professor David Begun and Dr. Ayla Sevim-Erol, of Ankara University.
Embryonic development constrains the evolution of phenotypes, which seems counterintuitive given the diversity of life forms. We use noctilionoid bats and their teeth to explore how development can both constrain and facilitate morphological evolution during adaptive radiations.
