After examining 22,000 years of rainfall patterns, Rutgers researchers warn that climate conditions may reduce fish stock New research involving Rutgers professors has revealed that expected, extreme changes in India’s summer monsoon could drastically hamper the Bay of Bengal’s ability to support a crucial element of the region’s food supply: marine life. The study, published in Nature Geoscience, was conducted by scientists from Rutgers University, the University of Arizona and collaborators from India, China and Europe. To reach their conclusions,…

UT Arlington research finds wastewater treatment plants are still not effectively removing dangerous microplastics Despite advances in wastewater treatment, tiny plastic particles called microplastics are still slipping through, posing potential health and environmental hazards, according to new research from The University of Texas at Arlington. Because plastic is inexpensive to produce yet lightweight and sturdy, manufacturers have found it ideal for use in nearly every consumer good, from food and beverage packaging to clothing and beauty products. The downside is…

Research team tests how stream contents and flow impact microplastic retention Microplastics, tiny plastic particles found in everyday products from face wash to toothpaste, are an emerging threat to health and ecology, prompting a research team to identify what keeps them trapped in stream ecosystems. Everyday actions like washing synthetic clothing and driving, which wears down tires, contribute to an accumulation of microplastics in environments from city dust to waterways. These plastics often carry toxic chemicals that can threaten the…

Global bird sightings from citizen scientists and view into “climate niches” reveals unexpected risks for some birds. Biologists have long debated why some plants and animals can adjust to a wide range of climates, while others can’t. Understanding why could help conservation managers and decision makers identify which species are most vulnerable to climate change. A new study in Nature Communications by researchers at The University of Texas at Austin evaluated global distribution maps and other data for about 1500…

New study uses modern molecular and evolutionary techniques to reassess a foundational, 67-year-old study in warblers A spat between birds at your backyard birdfeeder highlights the sometimes fierce competition for resources that animals face in the natural world, but some ecologically similar species appear to coexist peacefully. A classic study in songbirds by Robert MacArthur, one of the founders of modern ecology, suggested that similar wood warblers — insect-eating, colorful forest songbirds — can live in the same trees because…

With a prestigious Max Planck Fellowship (2025–2028), microbiologist Gabriele Berg from the Leibniz Institute for Agricultural Engineering and Bioeconomy (ATB) is launching a research collaboration with chemist Markus Antonietti at the Max Planck Institute of Colloids and Interfaces. Together, they’re developing a solution to soil exhaustion and infertility: a custom-made soil created in the lab from plant residues, enriched with carefully selected microorganisms. This biologically active soil is designed to restore microbial balance, support plant health, capture CO₂—and ultimately break…

Hereon researchers develop innovative method to calculate predator-prey relationships more precisely Marine food webs are highly complex. Until now, researchers have been unable to understand exactly how they are affected by climate change, overfishing and other threats. Scientists at the Helmholtz-Zentrum Hereon in Geesthacht have now achieved a breakthrough. They have developed a new computer model that can be used to simulate food webs more accurately than ever before. The work, which has been published in the journal Nature Ecology…

Urgent action is needed to protect endangered species, human health and industry from the impacts of the Caspian Sea shrinking, research led by the University of Leeds has found. Water levels in the Caspian Sea – the world’s largest landlocked water body – are getting lower, as hotter temperatures cause more water to evaporate than is flowing in. Even if global warming is limited to below 2°C, it is likely that the level of the Caspian Sea will decline by 5…

Researchers conduct batch adsorption testing in different soil types to understand the adsorption and aggregation behavior of nanoplastics in soil 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…

Australia’s exposure to extreme heat continues to grow while the country has emerged as a global hotspot for climate change litigation, according to the latest MJA–Lancet Countdown report. Released today, the report reveals Australia has experienced a 37 per cent increase in excess heat factor over the past 20 years. Lead author and Director of the Lancet Countdown Centre in Oceania, Professor Paul Beggs from Macquarie University, says these findings underscore the importance of long-term tracking of climate hazards and…

Freshwater ecosystems require adequate oxygen levels to sustain aerobic life and maintain healthy biological communities. However, both long-term climate warming and the increasing frequency and intensity of short-term heatwaves are significantly reducing surface dissolved oxygen (DO) levels in lakes worldwide, according to a new study published in Science Advances. Led by Prof. SHI Kun and Prof. ZHANG Yunlin from the Nanjing Institute of Geography and Limnology of the Chinese Academy of Sciences, in collaboration with researchers from the Nanjing University and the UK’s Bangor…

When wildfires threaten people’s communities, human health is impacted far beyond the inferno. Residual smoke distributes on the breeze, infiltrating homes, schools and offices. To help people protect themselves and their families, researchers have developed a low-cost, durable, do-it-yourself (DIY) air cleaner that works as well as more expensive HEPA filters to clear indoor air of pollutants such as smoke and possibly limit the impact of airborne disease spread. Richard Corsi, dean of the University of California, Davis (UC Davis)…

Sensors attached to animals gather valuable data to track and mitigate the human influence on marine life. The Kobe University review paper emphasizes the importance of integrating data from various sources and advocates for an “Internet of Animals” based on open access and shared standards. Humanity influences marine life through a broad range of activities, spanning from fishing and pollution to noise from boats, construction and mining. To enable a sustainable life together, we need to monitor the influence of…

Large and connected forests are better for harboring biodiversity than fragmented landscapes, according to research supported by Michigan State University. Ecologists agree that habitat loss reduces biodiversity. But they don’t agree whether it’s better to focus on preserving many smaller, fragmented tracts of land or fewer larger and more continuous landscapes. The study, published in Nature and conducted by researchers from Michigan State University, University of Michigan and the German Centre for Integrative Biodiversity Research among others, examined 4,006 species…

Scientists break down plastic using a simple, inexpensive catalyst and air Harnessing moisture from air, Northwestern University chemists have developed a simple new method for breaking down plastic waste. The non-toxic, environmentally friendly, solvent-free process first uses an inexpensive catalyst to break apart the bonds in polyethylene terephthalate (PET), the most common plastic in the polyester family. Then, the researchers merely expose the broken pieces to ambient air. Leveraging the trace amounts of moisture in air, the broken-down PET is…

The bottom of the Calypso Deep, a 5,112-metre deep depression in the Ionian Sea, contains one of the highest concentrations of marine debris in the deep ocean Waste generated by human activities has now reached the deepest point in the Mediterranean: the 5,112-metre-deep Calypso Deep in the Ionian Sea. A total of 167 objects — mainly plastics, glass, metal and paper — have been identified at the bottom, of which 148 are marine debris and 19 others are of possible…
