Early-onset El NiƱo means warmer winters in East Asia, and vice versa      (via sciencedaily.com)     Original source 

Researchers have found that the early onset of El Nino around June leads to warm winter climates in Japan, while the late onset of El Nino is associated with colder winters. By analyzing 100-ensemble member climate simulations over the past 61 years, the team found that the warming of the tropical Indian Ocean was a player in warmer Japanese winters.

Study explores what motivates people to watch footage of disasters and extreme weather      (via sciencedaily.com)     Original source 

The release in July 2024 of the blockbuster film Twisters (centred around a social-media celebrity storm-chaser) demonstrates an ongoing public fascination in hazards and extreme weather. The arrival of camera and streaming technologies have made it easier to collect and share such footage in recent years, resulting in often dramatic footage being live-streamed on platforms such as YouTube, TikTok and Discord. Now, a new study has analyzed what might be motivating people to watch these streams -- in some instances for up to 12 hours at a time.

Exploring the chemical space of the exposome: How far have we gone?      (via sciencedaily.com)     Original source 

Scientists have taken on the daunting challenge of mapping all the chemicals around us. They take inventory of the available science and conclude that currently a real pro-active chemical management is not feasible. To really get a grip on the vast and expanding chemical universe, they advocate the use of machine learning and AI, complementing existing strategies for detecting and identifying all molecules we are exposed to.

Organic material from Mars reveals the likely origin of life's building blocks      (via sciencedaily.com)     Original source 

Two samples from Mars together deliver clear evidence of the origin of Martian organic material. The study presents solid evidence for a prediction made over a decade ago that could be key to understanding how organic molecules, the foundation of life, were first formed here on Earth.

Dampening the 'seeds' of hurricanes      (via sciencedaily.com)     Original source 

Increased atmospheric moisture may alter critical weather patterns over Africa, making it more difficult for the predecessors of many Atlantic hurricanes to form, according to a new study.

Shrinking glaciers: Microscopic fungi enhance soil carbon storage in new landscapes created by shrinking Arctic glaciers      (via sciencedaily.com)     Original source 

Shrinking glaciers expose new land in the Arctic, creating unique ecosystems. Researchers studied how microbes colonize these barren landscapes. The study reveals a crucial role for specific fungal species in capturing and storing carbon in the newly formed soil. These findings suggest fungi are essential for future carbon storage in the Arctic as glaciers continue to recede.

Layers of carbonate provide insight into the world of the ancient Romans      (via sciencedaily.com)     Original source 

Archaeologists face a major challenge when they intend to acquire information about buildings or facilities of which only ruins remain. This was a particular challenge for the remnants of the Roman water mills in Barbegal in Southern France, dating back to the 2nd century CE. This unique industrial complex consisted of 16 water wheels placed in parallel rows. Little could at first be deduced about the site from these now scant ruins -- except that the wheels were supplied by an aqueduct that brought water from the surrounding hills. Researchers have now unraveled the history of the mill complex using calcium carbonate deposits that are now stored in the Archaeological Museum of Arles. These deposits had formed towards the end of the roughly 100-year operational life of the Barbegal water mills on the sides and base of the wooden supply system that conveyed the water to the wheels.

Novel spectroscopy technique sheds light on NOx reduction      (via sciencedaily.com)     Original source 

The process that can convert pollution into benign by-products is called selective catalytic reduction, or SCR. Until now, it has been unclear how this reaction actually occurs, and contradictions have long existed between reaction models within the literature. Catalysis researchers used a technology called modulation excitation spectroscopy, or MES, to finally identify the correct pathway.

Investigating newly discovered hydrothermal vents at depths of 3,000 meters off Svalbard      (via sciencedaily.com)     Original source 

Hydrothermal vents can be found around the world at the junctions of drifting tectonic plates. But there are many hydrothermal fields still to be discovered. During a 2022 expedition of the MARIA S. MERIAN, the first field of hydrothermal vents on the 500-kilometer-long Knipovich Ridge off the coast of Svalbard was discovered.

Ecologists reconstruct the history of biodiversity in the Indo-Australian archipelago and its rise as a hotspot      (via sciencedaily.com)     Original source 

The Coral Triangle, also known as the Indo-Australian Archipelago, is renowned for having the greatest marine biodiversity on our planet. Despite its importance, the detailed evolutionary history of this biodiversity hotspot has remained largely a mystery. An international research team has now shed light on this history, reconstructing how biodiversity in the region has developed over the past 40 million years.

Drowning in waste: Pollution hotspots in aquatic environments      (via sciencedaily.com)     Original source 

A new study explores waste management systems and reveals that achieving zero waste leakage by 2030 is unlikely, potentially jeopardizing related Sustainable Development Goals. The authors emphasize the need for global cooperation, particularly across four regions, to responsibly manage waste disposal.

Climate change to shift tropical rains northward      (via sciencedaily.com)     Original source 

Atmospheric scientists predict that unchecked carbon emissions will force tropical rains to shift northward in the coming decades, which would profoundly impact agriculture and economies near the Earth's equator. The northward rain shift would be spurred by carbon emissions that influence the formation of the intertropical convergence zones that are essentially atmospheric engines that drive about a third of the world's precipitation.

Antarctic ice shelves hold twice as much meltwater as previously thought      (via sciencedaily.com)     Original source 

Slush -- water-soaked snow -- makes up more than half of all meltwater on the Antarctic ice shelves during the height of summer, yet is poorly accounted for in regional climate models. The findings could have profound implications for ice shelf stability and sea level rise.
