Published Carbon dioxide's heavy stamp on temperature: Doubling CO2 may mean 7 to 14 degree increase



A doubling of the amount of CO2 in the atmosphere could cause an increase in the average temperature on earth from 7 to even a maximum of 14 degrees. That is shown in the analysis of sediments from the Pacific Ocean off the coast of California.
Published Promise green hydrogen may not always be fulfilled



Green hydrogen often, but certainly not always, leads to CO2 gains.
Published Up to 30 percent more time: Climate change makes it harder for women to collect water, study finds



By 2050, climate change could increase the amount of time women in households without running water spend collecting water by up to 30 percent on global average, according to a new study. In regions of South America and Southeast Asia, the time spent collecting water could double due to higher temperatures. Scientists estimate the large welfare losses that could result from climate impacts and highlights how women are particularly vulnerable to changing future climate conditions.
Published Restoring the Great Salt Lake would have environmental justice as well as ecological benefits



Inland seas around the world are drying up due to increasing human water use and accelerating climate change, and their desiccation is releasing harmful dust that pollutes the surrounding areas during acute dust storms. Using the Great Salt Lake in Utah as a case study, researchers show that dust exposure was highest among Pacific Islanders and Hispanic people and lower in white people compared to all other racial/ethnic groups, and higher for individuals without a high school diploma. Restoring the lake would benefit everyone in the vicinity by reducing dust exposure, and it would also decrease the disparities in exposure between different racial/ethnic and socioeconomic groups.
Published New study finds dinosaur fossils did not inspire the mythological griffin



For centuries, scientists thought they knew where the griffin legend came from. A new study takes a closer look at the data and folklore's influence on science.
Published Wild chimpanzees seek out medicinal plants to treat illness and injuries



Chimpanzees appear to consume plants with medicinal properties to treat their ailments, according to a new study.
Published Newly discovered dinosaur boasts big, blade-like horns



A new dinosaur has been identified and named. The dinosaur's name, Lokiceratops rangiformis, translates roughly to 'Loki's horned face that looks like a caribou.'
Published First conclusive evidence that a terrestrial leech species can jump



A new study presents video evidence that at least one species of terrestrial leech can jump, behavior that scientists have debated for more than a century.
Published Much of the Nord Stream gas remained in the sea



Much of the methane released into the southern Baltic Sea from the Nord Stream gas pipeline has remained in the water. This is shown by measurements taken by researchers from the University of Gothenburg.
Published When in drought: Researchers map which parts of the Amazon are most vulnerable to climate change



Some areas of the Amazon rainforest are more resilient to drought than others, new research shows. But if not managed carefully, we could 'threaten the integrity of the whole system,' researchers say.
Published Fishy parenting? Punishing offspring encourages cooperation



Scientists discovered that Neolamprologus savoryi fish use punishment to encourage offspring to cooperate in brood care, revealing advanced cognitive abilities previously thought unique to higher vertebrates. This study highlights that punishment for promoting cooperation exists beyond human societies, prompting a reevaluation of animal intelligence.
Published The world's oldest wine discovered



A white wine over 2,000 years old, of Andalusian origin, is the oldest wine ever discovered.
Published Where to put head and tail?



Formation of the body axes is a critical part of embryonic development. They guarantee that all body parts end up where they belong and that no ears grow on our backs. The head-tail axis, for example, determines the orientation of the two ends of the body. It was previously assumed that this axis is largely determined by the interplay between the Nodal and BMP signals. However, there appears to be another player in this system, as researchers have now discovered by using an embryo-like model system they developed. In the absence of BMP, the signalling molecule beta-catenin takes on the role of the Nodal antagonist. This new mechanism could be a flexible solution for axis formation in embryos with different shapes.
Published Advanced artificial intelligence: A revolution for sustainable agriculture



The rise of advanced artificial intelligence (edge AI) could well mark the beginning of a new era for sustainable agriculture. A recent study proposes a roadmap for integrating this technology into farming practices. The aim? To improve the efficiency, quality and safety of agricultural production, while addressing a range of environmental, social and economic challenges.
Published Climate change: rising temperatures may impact groundwater quality



As the world's largest unfrozen freshwater resource, groundwater is crucial for life on Earth. Researchers have investigated how global warming is affecting groundwater temperatures and what that means for humanity and the environment. Their study indicates that by 2100, more than 75 million people are likely to be living in regions where the groundwater temperature exceeds the highest threshold set for drinking water by any country.
Published An earthquake changed the course of the Ganges: Could it happen again?



A major earthquake 2,500 years ago caused one of the largest rivers on Earth to abruptly change course, according to a new study. The previously undocumented quake rerouted the main channel of the Ganges River in what is now densely populated Bangladesh, which remains vulnerable to big quakes.
Published Wear it, then recycle: Designers make dissolvable textiles from gelatin



Researchers hope their DIY machine will help designers around the world experiment with making their own, sustainable fashion and other textiles from a range of natural ingredients -- maybe even the chitin in crab shells or agar-agar from algae.
Published Ancient polar sea reptile fossil is oldest ever found in Southern Hemisphere



An international team of scientists has identified the oldest fossil of a sea-going reptile from the Southern Hemisphere -- a nothosaur vertebra found on New Zealand's South Island. 246 million years ago, at the beginning of the Age of Dinosaurs, New Zealand was located on the southern polar coast of a vast super-ocean called Panthalassa. 'The nothosaur found in New Zealand is over 40 million years older than the previously oldest known sauropterygian fossils from the Southern Hemisphere.
Published Improving soil health yields unexpected benefits for farmers



While farmer surveys suggest that carbon prices are still too low relative to the paperwork these programs demand, a new study finds that money alone does not explain either farmers' doubts about carbon markets or their interest in regenerative agriculture. Instead, many farmers view improving soil health as a way to improve their quality of life by reducing their dependence on agrochemical companies' products and advice.
Published Sharks have depleted functional diversity compared to the last 66 million years



New research has found that sharks retained high levels of functional diversity for most of the last 66 million years, before steadily declining over the last 10 million years to its lowest value in the present day.
