Published Warm summers and wet winters yield better wine vintages



Wine quality is notorious for varying from year to year, but what makes for a 'good year?' Researchers show that weather plays an important role in determining wine quality. By analyzing 50 years’ worth of wine critic scores from the Bordeaux wine region in relation to that year’s weather, the researchers showed that higher quality wine is made in years with warmer temperatures, higher winter rainfall, and earlier, shorter growing seasons—conditions that climate change is predicted to make more frequent.
Published Titanium oxide material can remove toxic dyes from wastewater



Discharged in large quantities by textile, cosmetic, ink, paper and other manufacturers, dyes carry high-toxicity and can bring potential carcinogens to wastewater. It’s a major concern for wastewater treatment — but researchers may have found a solution, using a tiny nanofilament.
Published Paleoclimatologists use ancient sediment to explore future climate in Africa



With global warming apparently here to stay, a team of paleoclimatologists are studying an ancient source to determine future rainfall and drought patterns: fossilized plants that lived on Earth millions of years ago.
Published Modular dam design could accelerate the adoption of renewable energy



Scientists have developed a new modular steel buttress dam system designed to resolve energy storage issues hindering the integration of renewable resources into the energy mix. The new modular steel buttress dam system facilitates the rapid construction of paired reservoir systems for grid-scale energy storage and generation using closed-loop pumped storage hydropower, cutting dam construction costs by one-third and reducing construction schedules by half.
Published Ecotoxicity testing of micro- and nano-plastics



An international team of researchers has published the first harmonized exposure protocol for ecotoxicity testing of microplastics and nanoplastics.
Published The changing climate creates more noise in the oceans



Due to the changing climate, the underwater world is getting ever noisier.
Published Discovery of invisible nutrient discharge on Great Barrier Reef raises concerns



Scientists using natural tracers off Queensland’s coast have discovered the source of previously unquantified nitrogen and phosphorus having a profound environmental impact on the Great Barrier Reef. Groundwater discharge accounted for approximately one-third of new nitrogen and two-thirds of phosphorus inputs, indicating that nearly twice the amount of nitrogen enters the Reef from groundwater compared to river waters.
Published Tropical ecosystems more reliant on emerging aquatic insects, study finds, potentially putting them at greater risk



Researchers have found that tropical forest ecosystems are more reliant on aquatic insects than temperate forest ecosystems, making them more vulnerable to disruptions to the links between land and water. This is a significant finding, as tropical forests play a vital role in global biodiversity and climate regulation. The study's authors warn that any disruption to the land-water connections in these ecosystems could have serious consequences for their health and resilience.
Published The Gulf Stream is warming and shifting closer to shore



The Gulf Stream is intrinsic to the global climate system, bringing warm waters from the Caribbean up the East Coast of the United States. As it flows along the coast and then across the Atlantic Ocean, this powerful ocean current influences weather patterns and storms, and it carries heat from the tropics to higher latitudes as part of the Atlantic Meridional Overturning Circulation. A new study now documents that over the past 20 years, the Gulf Stream has warmed faster than the global ocean as a whole and has shifted towards the coast. The study relies on over 25,000 temperature and salinity profiles collected between 2001 and 2023.
Published Ancient Maya reservoirs offer lessons for today's water crises



Ancient Maya reservoirs, which used aquatic plants to filter and clean the water, 'can serve as archetypes for natural, sustainable water systems to address future water needs.' The Maya built and maintained reservoirs that were in use for more than 1,000 years. These reservoirs provided potable water for thousands to tens of thousands of people in cities during the annual, five-month dry season and in periods of prolonged drought.
Published Consistent metabolism may prove costly for insects in saltier water



Increased salinity usually spells trouble for freshwater insects like mayflies. A new study finds that the lack of metabolic responses to salinity may explain why some freshwater insects often struggle in higher salinity, while other freshwater invertebrates (like mollusks and crustaceans) thrive.
Published Deciphering the intensity of past ocean currents



Ocean currents determine the structure of the deep-sea ocean floor and the transport of sediments, organic carbon, nutrients and pollutants. In flume-tank experiments, researchers have simulated how currents shape the seafloor and control sediment deposition. This will help in reconstructions of past marine conditions.
Published Shining a light on tiny, solar-powered animals



Acoels have been found to host a wide diversity of symbiotic, photosynthetic microalgae.
Published Bewick's swans choose wintering areas based on the weather



Bewick’s swans fly less far during their autumn migration when the weather is warm. Climate change has therefore led to a shift in their common wintering areas. Now, for the first time, bird researchers have been able to use long-term GPS data to pinpoint the specific choices that individual swans make.
Published Early human migrants followed lush corridor-route out of Africa



Scientists have found early human migrants left Africa for Eurasia, across the Sinai peninsula and on through Jordan, over 80-thousand years ago. Researchers have proved there was a 'well-watered corridor' which funneled hunter-gatherers through The Levant towards western Asia and northern Arabia via Jordan.
Published Meadow Spittlebug's record-breaking diet also makes it top disease carrier for plants



New research fueled in part by citizen scientists reveals that the meadow spittlebug—known for the foamy, spit-like urine released by its nymphs—can feed on at least 1,300 species of host plants, more than twice the number of any other insect.
Published Staying dry for months underwater



Researchers have developed a superhydrophobic surface with a stable plastron that can last for months under water. The team’s general strategy to create long-lasting underwater superhydrophobic surfaces, which repel blood and drastically reduce or prevent the adhesion of bacterial and marine organisms such as barnacles and mussels, opens a range of applications in biomedicine and industry.
Published Ancient carbon in rocks releases as much carbon dioxide as the world's volcanoes



New research has overturned the traditional view that natural rock weathering acts as a carbon sink that removes CO2 from the atmosphere. Instead, this can also act as a large CO2 source, rivaling that of volcanoes.
Published Invertebrate biodiversity is improving in England's rivers, long-term trends show



Rivers across England have seen a significant improvement in river invertebrate biodiversity since 1989, shows a new study.
Published Birders and AI push bird conservation to the next level



Big data and artificial intelligence (AI) are being used to model hidden patterns in nature, not just for one bird species, but for entire ecological communities across continents. And the models follow each species’ full annual life cycle, from breeding to fall migration to non-breeding grounds, and back north again during spring migration.
