That’s a key ...

Plastics are everywhere—from packaging and textiles to electronics and medical devices. As plastic waste breaks down, it releases microscopic particles that can penetrate our ecosystems, hinder plant growth, and potentially transfer harmful pollutants to organisms, including humans. Therefore, these plastic particles are a potential threat to the ecosystem, especially in their nanoparticulate form (1–100 nm diameter), which can penetrate the environment through different routes, including the soil beneath our feet. With this in mind, a team of researchers from Japan set out to study the migration behavior of nanoplastics ...

Coupling reactions are among the most transformative tools in organic chemistry, enabling the formation of crucial chemical bonds in pharmaceuticals, agrochemicals, and advanced materials.

A review published in The Laryngoscope indicates that climate change’s effects on pollen seasons and concentrations are contributing to increasing rates of allergic rhinitis, or hay fever. When investigators assessed research published between 2000 and 2023, they identified 30 studies that reported on the current epidemiological state of allergic rhinitis, described factors related to climate change, and observed how global warming is affecting pollen seasons and allergy symptoms. Sixteen studies reported longer pollen seasons and/or higher pollen concentrations related to climate change. As an example, total pollen emissions in the U.S. are projected to increase by 16–40% ...

Several states, including Georgia, offer state-funded pre-kindergarten programs to students regardless of their family’s income. New research in Economic Inquiry investigates whether such programs offer long-lasting academic benefits to all students. Using enrollment lottery data from a large school district in metro Atlanta, investigators found that lottery-winning enrollees of school-based pre-kindergarten entered kindergarten more prepared in both math and reading than non-winning peers. Gains tended to fade by the end of kindergarten, however, and some negative achievement effects ...
