Oct. 9, 2024 Toxic trace elements such as lead, mercury, arsenic, and cadmium naturally occur in small quantities in coastal seas. However, human activities, such as industry and agriculture, contribute significantly larger amounts. A new study has examined how climate change already affects the distribution and accumulation of these elements and how it could impact them in the future. One of the findings: ...

Oct. 7, 2024 Researchers have created a high-performance polymer that can be chemically recycled without compromising its heat and chemical resistance. The revolutionary design includes a directing group that allows links in the polymer to be broken easily with a catalyst and the original polymer to be reformed in few steps. The directing group could be included in many polymers, potentially providing a new ...

Oct. 7, 2024 Researchers conducted innovative simulations of spinning black holes grounded in general relativity, which clarified that the ultraluminous accretion disk (i.e., gaseous spiral surrounding a black hole) exhibits a precessional motion driven by the black hole's spin. This finding underscores the potential of this spin to be the primary driver of ...

Oct. 3, 2024 Looking deep into the early universe with NASA's James Webb Space Telescope, astronomers have found something unprecedented: a galaxy with an odd light signature, which they attribute to its gas outshining its stars. Found approximately one billion years after the big bang, galaxy GS-NDG-9422 (9422) may be a missing-link phase of galactic evolution between the universe's first stars and familiar, ...
