UV radiation fluctuates amid wet-dry extremes in clear water bodies Lake Tahoe is experiencing large-scale shifts in ultraviolet radiation (UV) as climate change intensifies wet and dry extremes in the region. That is according to a study led by the University of California, Davis’ Tahoe Environmental Research Center and co-leading collaborator Miami University in Ohio. For the study, published in ASLO, the journal of the Association for the Sciences of Limnology and Oceanography, scientists analyzed an 18-year record of underwater irradiance…
The ‘Barbarian Conspiracy’ of 367 CE was one of the most severe threats to Rome’s hold on Britain since the Boudiccan revolt three centuries earlier. Contemporary sources indicate that components of the garrison on Hadrian’s wall rebelled and allowed the Picts to attack the Roman province by land and sea. Simultaneously, the Scotti from modern-day Ireland invaded broadly in the west, and Saxons from the continent landed in the south. Senior Roman commanders were captured or killed, and some soldiers…
In the global carbon cycle microorganisms have evolved a variety of methods for fixing carbon. Researchers from Bremen and Taiwan have investigated the methods that are utilized at extremely hot, acidic and sulfur-rich hydrothermal vents in shallow waters off the island of Kueishantao, Taiwan. A team working with first author Joely Maak of MARUM – Center for Marine Environmental Sciences at the University of Bremen has now published their study in the professional journal Biogeosciences. Extremely harsh conditions can be…
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…
Is sauerkraut more than just a tangy topping? A new University of California, Davis, study published in Applied and Environmental Microbiology suggests that the fermented cabbage could help protect your gut, which is an essential part of overall health, supporting digestion and protecting against illness. Authors Maria Marco, professor with the Department of Food Science and Technology, and Lei Wei, a postdoctoral researcher in Marco’s lab, looked at what happens during fermentation — specifically, how the metabolites in sauerkraut compared to those…
The sun may rise every morning, but the amount of sunlight reaching the Earth’s surface can substantially vary over decades, according to a perspectives article led by an international research team. The article, published on March 15 in Advances in Atmospheric Science, suggests that stages of “dimming” and “brightening” correspond with increased air pollution and implementation of clean energy solutions, respectively. “The amount of sunlight — which is solar radiative energy — we receive at the Earth’s surface is not…
New research explores geological processes along plate boundaries Being a geophysicist can sometimes feel like being a detective —uncovering clues, and then building a case based on the evidence. In a new article published in Science Advances, a collaborative team led by the Woods Hole Oceanographic Institution (WHOI), presents a never-before-seen image of an oceanic transform fault from electromagnetic (EM) data collected at the Gofar fault in the eastern Pacific Ocean. The National Science Foundation funded work reveals unexpected brine…
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…
In a groundbreaking study published in Science, a research team led by Prof. YE Jian from the Institute of Microbiology of the Chinese Academy of Sciences has identified the first mechanism of citrus resistance to citrus greening disease, or huanglongbing (HLB). Utilizing artificial intelligence (AI), the team has also developed antimicrobial peptides that offer a promising therapeutic approach to combat the disease. This discovery addresses a long-standing challenge in the agricultural community—the absence of naturally occurring HLB-resistant genes in citrus….
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…
A new study maps how specific lactic acid bacteria can enhance both the flavour and nutritional quality of plant-based dairy alternatives. The findings may have wide-reaching perspectives for the further development of sustainable foods. Plant-based dairy alternatives – such as soy, oat, and almond drinks – are produced without animal ingredients for consumers seeking plant-based substitutes for milk and yoghurt. However, many of these products have the similar shortcomings: flavours that do not always appeal to consumers, and nutritional profiles…
A study recently published in Nature indicates that human activities have a negative effect on the biodiversity of wildlife hundreds of kilometres away. A research collaboration led by the University of Tartu assessed the health of ecosystems worldwide, considering both the number of plant species found and the dark diversity – the missing ecologically suitable species. For the study, over 200 researchers among them one scientist from the Helmholtz Centre for Environmental Research (UFZ) and the German Centre for Integrative…
