Combinations of climate extremes may prompt carbon budget rethink
Combined extreme climate events are likely to become more common in the future if carbon emissions continue to rise, a paper in Nature suggests. The study finds that the frequency of compound events—such as concurrent hot–wet and drought–heat extremes—is linked to cumulative
Discovery of antimicrobial peptides in ant venom has far-reaching implications
In addition to serving as biochemical weapons for offense and defense, the venoms produced by ants in the subfamily Formicinae also fulfill additional roles. For example, the ants use it to protect their nests from pathogens. It has long been assumed that the primary
Large-scale eDNA survey reveals hidden factors that affect regional fish communities
As climate change and human activities continually ramp up, fish are forced to find ways to adapt. As fish move around to find more suitable habitats as ocean conditions shift, regional fish distributions change—which can have huge downstream effects on local ecosystems.
Mathematicians prove existence of Kaleidocycles then unlock their exact motion
Kaleidocycles are flexible polyhedral structures composed of rigid tetrahedra connected along their edges to form rotating rings. Each tetrahedron is a solid 3D polygon with four triangular faces (like a triangular pyramid), and the hinges connect neighboring units, enabling a
Astrophysicists use 'space archaeology' to trace the history of a spiral galaxy
Billions of years ago, a young spiral galaxy began to grow in a crowded part of the universe. It pulled in gas and small companion galaxies, slowly building up the bright central region and sweeping spiral arms we see today.
Will future missions to the moon be sustainable? It may depend on whom you ask
