A new review in Nature examines progress in using amidases and urethanases as biocatalysts to depolymerize synthetic polymers. The work surveys how these enzymes can break down plastic-like materials, an emerging approach in biological recycling that could complement chemical methods. Researchers see enzyme-driven depolymerization as a promising route to recovering monomers from plastic waste.

A Nature retrospective revisits the 1966 Nobel Prize in Physics, awarded to Alfred Kastler for the discovery and development of optical methods for studying atomic spectra, work known as optical pumping. The piece highlights how the achievement rested on collaboration across laboratories and laid foundations for later developments in atomic physics and laser science.

Public health researchers are promoting the idea of 'slow epidemiology', arguing that better science means asking clearer questions, using more rigorous study designs, reporting methods transparently, and running thorough sensitivity analyses. Proponents frame it as embracing the cutting edge of research practice rather than repeating past habits, at a time when fast, AI-assisted health research is raising concerns about quality.

Scientists report the discovery of a so-called third state of being that sits between life and death, challenging the traditional binary view of biological existence. The finding is drawing attention for its potential implications for biology, medicine, and how scientists define when life ends. Details of the research and its methods remain limited in early coverage.

A New York Times report examines how Christa Pike, the woman on death row in Tennessee, survived two administrations of the lethal injection drug pentobarbital during her execution process. The article explores the medical and scientific questions raised by the failed injections, reigniting debate over the reliability and humanity of lethal injection as a method of execution in the United States.

Researchers are turning to wildlife tracking technology to address long-standing gaps in scientific understanding of monarch butterfly migration. The effort aims to map the insects' routes and behaviour more precisely than traditional tagging methods have allowed. Details about the specific technology, the institutions involved and the study's timeline remain limited, but the work targets one of the best-known yet still incompletely understood migrations in the insect world.

Zenithon AI is presenting itself as a startup working on simulating extreme physics up to a million times faster than existing methods. The company appears in startup database listings, but little verified detail is available about its technology, funding, or team. The claim of such a large speed increase in physics simulation would, if proven, be significant for engineering and scientific research.

Researchers have developed Nanomeritics, a new approach aimed at strengthening the characterization of nanoparticles. The method is presented as a way to improve how scientists measure and analyze nanoscale materials, a step that could support more reliable research and development across nanotechnology. Details beyond the announcement remain limited, and reaction from the wider scientific community is not yet documented.
