Theoretical models of supernova chemistry overhauled after X-ray data from Perseus Cluster reveal key discrepancies‎

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 have exploded throughout cosmic history.

Hollow-sphere catalyst enables greener production of 99% pure propane at room temperature‎

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.

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

A paper published in the journal Science Advances is adding to the growing body of research showing that the Atlantic Meridional Overturning Circulation (AMOC) is weakening. In this new study, instead of relying mainly on computer models, scientists used two decades of direct ocean measurements to confirm the decline.

What happens when men don't feel 'man enough'?‎

A research team led by Lea Lorenz of the RPTU University Kaiserslautern-Landau and Sven Kachel of the University of Kassel conducted a comprehensive meta-analysis that examined how men react to situations in which their masculinity is called into question. To this end, the team systematically organized and analyzed 123 experiments, predominantly from Western countries, involving 19,448 men.
