Researchers introduce generative AI for databases      (via sciencedaily.com)     Original source 

Researchers have developed an easy-to-use tool that enables someone to perform complicated statistical analyses on tabular data using just a few keystrokes. Their method combines probabilistic AI models with the programming language SQL to provide faster and more accurate results than other methods.

Groundbreaking study reveals oceanic seabirds chase tropical cyclones      (via sciencedaily.com)     Original source 

A new study reveals that the rare Desertas Petrels (Pterodroma deserta), a wide-ranging seabird in the North Atlantic, exhibit unique foraging behaviors during hurricane season. Contrary to other pelagic seabirds, these petrels do not avoid intense tropical cyclones but instead exploit the dynamic conditions for their benefit, providing new insights into the impact of cyclones on open ocean marine life.

Weaker ocean circulation could enhance carbon dioxide buildup in the atmosphere, study finds      (via sciencedaily.com)     Original source 

Scientists may have to rethink the relationship between the ocean's circulation and its long-term capacity to store carbon, new research suggests. As the ocean gets weaker, it could release more carbon from the deep ocean into the atmosphere -- rather than less, as some have predicted.

Exploring the radiative effects of precipitation on Arctic amplification and energy budget      (via sciencedaily.com)     Original source 

While, in theory, precipitation impacts the Earth's radiation budget, the radiative effects of precipitation (REP) are poorly understood and excluded from most climate models. Hence, a new study examined the role of REP in the global and regional energy budgets and hydrological cycles, finding that REP significantly contributes to temperature and precipitation variations at different geographical scales, especially in the Arctic warming. This highlights the relevance of including REP in climate modeling for improved accuracy.

The dawn of the Antarctic ice sheets      (via sciencedaily.com)     Original source 

In recent years global warming has left its mark on the Antarctic ice sheets. The 'eternal' ice in Antarctica is melting faster than previously assumed, particularly in West Antarctica more than East Antarctica. The root for this could lie in its formation, as an international research team has now discovered: sediment samples from drill cores combined with complex climate and ice-sheet modelling show that permanent glaciation of Antarctica began around 34 million years ago -- but did not encompass the entire continent as previously assumed, but rather was confined to the eastern region of the continent (East Antarctica).

Deep machine-learning speeds assessment of fruit fly heart aging and disease, a model for human disease      (via sciencedaily.com)     Original source 

Drosophila -- known as fruit flies -- are a valuable model for human heart pathophysiology, including cardiac aging and cardiomyopathy. However, a choke point in evaluating fruit fly hearts is the need for human intervention to measure the heart at moments of its largest expansion or its greatest contraction to calculate cardiac dynamics. Researchers now show a way to significantly cut the time needed for that analysis while utilizing more of the heart region, using deep learning and high-speed video microscopy.

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.

Melting of Alaskan glaciers accelerating faster than previously thought      (via sciencedaily.com)     Original source 

Melting of glaciers in a major Alaskan icefield has accelerated and could reach an irreversible tipping point earlier than previously thought. The research found that glacier loss on Juneau Icefield, which straddles the boundary between Alaska and British Columbia, Canada, has increased dramatically since 2010. The team looked at records going back to 1770 and identified three distinct periods in how icefield volume changed. In particular, they found that icefield-wide, rates of glacier area shrinkage were five times faster from 2015-2019 relative to 1948-1979. The research team say that current published projections for the Juneau icefield may need to be updated to reflect the processes detailed in this latest study.

Unraveling the origin and global spread of the potato blight pathogen      (via sciencedaily.com)     Original source 

A new study challenges the common theory that the devastating potato blight pathogen Phytophthora infestans originated in Mexico. Researchers meticulously reconstructed its global migration history and found it likely originated in the South American Andes before spreading globally. This research provides significant insights into the pathogen's evolutionary journey, which is crucial for developing better disease management strategies worldwide.

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.
