The Nature Conservancy is advertising for a Marine Conservation Director, a senior role leading its ocean protection work. The opening is being circulated on ocean career listings, drawing interest from marine scientists and conservation professionals looking to shape policy and coastal conservation programmes at a global environmental organisation.

Scientists are highlighting new research showing that too much phosphorus in water triggers eutrophication, oxygen depletion and, in extreme cases, conditions comparable to those behind past mass extinction events. The warning, published in Nature Communications, notes that nutrient overload drives anoxia in oceans and lakes, and commentators are using the findings to stress that even beneficial nutrients become dangerous at scale.

Scientists analysed lead trapped in the dental enamel of human teeth from a medieval English town, pinpointing when residents first began being poisoned by the toxic metal. The findings offer a precise timeline of lead exposure in the period, shedding light on everyday environmental pollution centuries before the industrial era.

Researchers highlight cpn60, a housekeeping gene, as an effective marker for profiling living microbial communities. Unlike common ribosomal markers, cpn60 can distinguish active organisms within complex microbiomes, making it useful in health, environmental and food microbiology. The gene's variability offers finer resolution for identifying species and tracking microbial diversity in samples where many microbes are difficult to culture.

Florida Climate Week is underway, drawing attention to the environmental challenges facing the state, including rising seas, warming waters and coastal erosion. Events across the week also highlight ocean research being conducted in Florida, with scientists and organisations using the occasion to discuss the impacts of climate change on the region's ecosystems and coastal communities.

Kevin Wilkinson discusses new work tracing airborne metal pollution at the level of individual particles. The approach uses spectroscopic techniques to identify metal-bearing particles in the air, offering a finer-grained picture of pollution sources and exposure than bulk measurements allow. The research is of interest to environmental scientists and air-quality specialists following advances in particle-level pollution analysis.

UK scientists are exploring biological methods to produce lithium in a cleaner, more environmentally friendly way, according to The Northern Miner. The research aims to reduce the environmental impact of traditional lithium extraction, which is energy-intensive and water-heavy. Interest in greener lithium supplies is growing as demand rises for electric vehicle batteries and renewable energy storage worldwide.

A new essay explores how aging dogs could help Alzheimer's researchers. Dogs naturally develop cognitive decline and amyloid brain changes similar to those seen in humans, making them useful models for studying dementia. Because pet dogs live alongside people and share environmental exposures, scientists are considering whether canine aging studies could reveal earlier warning signs or test treatments faster than human trials allow.

Scientists report that the shrinking Dead Sea is generating its own extreme local climate conditions. As the water level drops, the exposed lakebed and reduced water surface are altering temperature, evaporation and weather patterns in the surrounding region. The findings highlight how dramatically the famous salt lake's decline over recent decades is reshaping not just the landscape but the environment around it, raising concern among researchers and environmental observers.

Scientists in Athens have organised a forum bringing local election candidates together to discuss energy policy and environmental issues. The event gives voters a chance to hear where contenders stand on climate, power and sustainability matters ahead of the vote. Details about which candidates attended and what positions they took were not immediately available.

Scientists are promoting exposome science — the mapping of the total accumulated environmental exposures a child experiences, from air pollution and chemicals to diet and social conditions — as a way to rewrite pediatric health research. Rather than studying single risk factors in isolation, researchers say tracking the full range of exposures over childhood could reveal the cumulative roots of chronic disease and guide earlier interventions. The approach is gaining attention as a new framework in children's medicine.

Researchers have published PAWI, described as the first high-resolution, multi-class pan-Arctic wetland inventory, in the Journal of Environmental Management. The dataset is also accessible through Canada's Geo.ca map browser. It offers a detailed, classification-based mapping of wetlands across the entire Arctic region, a resource of interest for climate and permafrost scientists, since Arctic wetlands are significant sources of methane emissions.

Selena Liang has interviewed Dr. Debra Roberts, environmental scientist and co-chair of the Intergovernmental Panel on Climate Change, about a range of climate issues. Their conversation covered temperature overshoot, adaptation strategies, the role of nuclear energy, and the importance of holding reasonable expectations for climate action. The interview offers a senior IPCC voice on how far current efforts can realistically go.

Researchers have developed a bioengineered model that simulates how the human placenta is exposed to environmental metals such as cadmium and lead during pregnancy. Published in Nature, the system offers a way to study toxic metal transfer from mother to fetus without relying on animal testing or direct human sampling. The work could help scientists better understand developmental risks from pollution.

A long-term look at the Olowalu reef off Maui, Hawaii, is shedding light on how the marine ecosystem has changed over roughly the past 200 years, reflecting shifts from human activity and environmental pressures. The reef, considered one of the most important coral systems on Maui, offers scientists a natural record of conditions dating back two centuries. Coverage so far is limited, with details of the findings not yet widely circulated.

Scientists are urging consumers worldwide to stop buying products made from Antarctic krill, citing the need to protect whales, penguins and other marine life that depend on krill as a food source. The call comes as major retailers begin withdrawing krill-based products, often sold as supplements, from their shelves. Supporters of the boycott say reduced consumer demand is needed to ease pressure on the fragile Antarctic ecosystem.
