Atlantic current shows two-decade decline across four deep-ocean monitoring sites

The Perseus Cluster is a massive galaxy cluster located in the constellation Perseus. It is one of the largest structures in the observable universe, comprising more than a thousand galaxies—equivalent to roughly a thousand trillion times the mass of the sun. Hot gases within the cluster, known as the intracluster medium (ICM), emit powerful X-rays detectable by telescopes. These gases are produced by billions of supernova explosions, and their chemical composition reveals how typical supernovae

The lakes, streams, and ponds you've visited for years are likely looking more brown than they used to. And people who are fishing those waters are likely catching different species and sizes of fish than in the past.

French mathematician Frank Merle, who won a prestigious Breakthrough Prize on Saturday, told AFP that fundamental research must be supported because it is a "foundation stone" for the future.

The world's appetite for propene (propylene) is growing faster than the chemical industry can keep up. This petrochemical product powers the production of acrylonitrile, propylene oxide, high-velocity fuels, and, most importantly, polypropylene plastic—used in everyday food packaging and textiles, as well as in essential medical equipment.
