New images of the sun captured by the Solar Orbiter mission showcase the highest-resolution views of our star’s visible surface ever seen, revealing sunspots and continuously moving charged gas called plasma. The images could provide heliophysicists with new clues to help unlock the secrets of the sun like never before. The images, taken…

General relativity has passed one of its most precise tests ever thanks to observations of the past 11 billion years of cosmic evolution collected by the Dark Energy Spectroscopic Instrument, or DESI. Albert Einstein's 1915 theory, general relativity, has remained humanity's best description of gravity for the past 100 years. Cosmologists have used general relativity to model how the…

R esearchers from the University of Birmingham, UK, have developed an intriguing computer model to understand how light and matter interact. As tasks go, it is exceptionally hard, but the team was able to develop a strategy to simplify the problem. In doing so, they were also able to create something peculiar: an image representing…

Scientists have reprogrammed mouse cells into pluripotent stem cells using a gene from choanoflagellates, single-celled organisms related to animals. This breakthrough demonstrates that key genes driving stem cell formation existed in unicellular ancestors nearly a billion years ago. The resulting stem cells were used to create a chimeric mouse, showcasing how ancient genetic tools can…
