The discovery that a toxin made by bacteria found in dirty water might help trigger ulcerative colitis could lead to new treatments for this form of IBD

Astronauts strapped moss spores to the outside of the International Space Station for nine months - and most of them survived the challenging experience

Scientists have observed mice helping each other when they encounter difficulties during birth, prompting a rethink of caregiving among rodents and other animals 

Over the course of billions of years, the universe has steadily been evolving. Thanks to the expansion of the universe, we are able to “see” back in time to watch that evolution, almost from the beginning. But every once in a while we see something that doesn’t fit into our current understanding of how the universe should operate. That’s the case for a galaxy described in a new paper by PhD student Sijia Cai of Tsinghua University’s Department of Astronomy and their colleagues. They found a galaxy formed around 11 billion years ago that appears to be “metal-free”, indicating that it might contain a set of elusive first generation (Pop III) stars.

All of the proposals floating around out there for invoking dynamical dark energy are a little on the weak side. In many cases, they raise more questions than answers.

NASA spacecraft across the inner solar system captured new views of Comet 3I/ATLAS—the third known interstellar object

Researchers using the NASA/ESA/CSA James Webb Space Telescope have confirmed an actively growing supermassive black hole within a galaxy just 570 million years after the Big Bang. Part of a class of small, very distant galaxies that have mystified astronomers, CANUCS-LRD-z8.6 represents a vital piece of this puzzle that challenges existing theories about the formation of galaxies and black holes in the early Universe. The discovery connects early black holes with the luminous quasars we observe today.

A newly discovered cluster of objects called the “inner kernel” of the Kuiper belt could teach us about the early history of the solar system – including the movement of Neptune
