Research shows that older mothers produce faster-growing and more resilient larvae, while smaller ants disrupt native seed dispersal patterns. Exotic plants also adapt quickly to new environments, and artificial night lighting can harm migrating birds.
Researchers studied coral outbreaks off the island of Curacao, finding high concentrations of metals and human pathogens near major oil refineries. The team suggests that environmental stresses caused by pollution may be weakening corals' resistance to bacterial infection.
University at Buffalo chemists found that nitric oxide is highly reactive with ethanol, making it a potentially more insidious pollutant. The study's findings provide new insights into how solvation affects chemical reactions and could help scientists better tailor lab experiments.
Ground-level ozone levels are high enough to reduce growth and yield of sensitive plants on Long Island, where important agriculture is located. White clover has been particularly affected, with a 24-27% reduction in growth rate.
New research suggests that aerosol pollutants in the atmosphere are likely masking global warming. Aerosols can modify clouds, suppress precipitation, and reflect light, cooling the Earth. This effect may be as large as the warming caused by human emissions of greenhouse gases.
Researchers at Purdue University have developed a method to measure pollutants produced by combustion, using laser-induced fluorescence. This technique has the potential to significantly reduce nitric oxide production in next-generation jet engines, designed for lean direct injection.
Scientists have discovered a species of glowing bacteria that can detect pollutants in the deep sea. When exposed to various toxic substances, Photobacterium phosphoreum HE-1a glows up to 50% less brightly, triggering an alarm call that alerts nearby sensors to take action.
