Sharing chemical knowledge between human and machine      (via sciencedaily.com) 

Researchers have developed a platform that uses artificial neural networks to translate chemical structural formulae into machine-readable form. With this platform, they have created a tool with which this information from scientific publications can be automatically fed into databases. Until now, this had to be done literally by hand and was time-consuming.

'Coastal squeeze:' Massive loss of U.S. coastline tidal flats over 31 years      (via sciencedaily.com)     Original source 

The entire contiguous U.S. has experienced massive urban expansions and the Atlantic Coast shows outstandingly high rates. Urban expansion has substantially squeezed the space of tidal flats and affected surrounding environments. In new urban areas, tidal flats have undergone considerable degeneration with more significant patterns as they get closer to new urban locations. Tidal flats protect against the ocean's destructive powers such as hurricanes. Without some inland spaces to move around, they will likely disappear, which will have dire consequences for beachfront communities.

Thinning ice sheets may drive sharp rise in subglacial waters      (via sciencedaily.com)     Original source 

A new study shows that water underneath glaciers may surge due to thinning ice sheets -- a dangerous feedback cycle that could increase glacial melt, sea level rise, and biological disturbances.

Unprecedented look at what influences sea ice motion in the Arctic      (via sciencedaily.com)     Original source 

The in-depth analysis reveals how local tidal currents strongly affect the movement of sea ice in the Arctic ocean and provides an unprecedented look at how the makeup of the seafloor is causing some of the most abrupt changes.

Oceans release microplastics into the atmosphere      (via sciencedaily.com)     Original source 

Tiny plastic particles can be found in the air over the oceans even far away from the coast. According to a new study, microplastics are not only carried by the wind, but also escape into the atmosphere from seawater. Researchers present data on the composition and sources of different types of plastic in the air over the North Atlantic and the origin of the particles.

Could artificially dimming the sun prevent ice melt?      (via sciencedaily.com)     Original source 

With methods of so-called geoengineering, the climate could theoretically be artificially influenced and cooled. Researchers have now investigated whether it would be possible to prevent the melting of the West Antarctic ice sheet by artificially 'dimming the sun'. The results show that artificial influence does not work without decarbonization and entails high risks.

A roadmap to help AI technologies speak African languages      (via sciencedaily.com) 

From text-generating ChatGPT to voice-activated Siri, artificial intelligence-powered tools are designed to aid our everyday life -- as long as you speak a language they support. These technologies are out of reach for billions of people who don't use English, French, Spanish or other mainstream languages, but researchers in Africa are looking to change that. Scientists now draw a roadmap to develop better AI-driven tools for African languages.

Microplastics found embedded in tissues of whales and dolphins      (via sciencedaily.com)     Original source 

Microscopic plastic particles have been found in the fats and lungs of two-thirds of the marine mammals in a graduate student's study of ocean microplastics. The presence of polymer particles and fibers in these animals suggests that microplastics can travel out of the digestive tract and lodge in the tissues.

Turning ChatGPT into a 'chemistry assistant'      (via sciencedaily.com) 

Developing new materials requires significant time and labor, but some chemists are now hopeful that artificial intelligence (AI) could one day shoulder much of this burden. In a new study, a team prompted a popular AI model, ChatGPT, to perform one particularly time-consuming task: searching scientific literature. With that data, they built a second tool, a model to predict experimental results.

Top fish predators could suffer wide loss of suitable habitat by 2100 due to climate change      (via sciencedaily.com)     Original source 

A study of 12 species of highly migratory fish predators -- including sharks, tuna, and billfish such as marlin and swordfish -- finds that most of them will encounter widespread losses of suitable habitat and redistribution from current habitats in the Northwest Atlantic Ocean (NWA) and the Gulf of Mexico (GOM) by 2100. These areas are among the fastest warming ocean regions and are projected to increase between 1-6°C (+1-10°F) by the end of the century, a sign of climate-driven changes in marine ecosystems.

Land-sea relationship is major driver of coral reef health outcomes      (via sciencedaily.com)     Original source 

New research indicates that mitigating both local land and sea-based human impacts, especially in terms of pollutants and over-fishing, provides coral reef ecosystems with the best opportunity to persist under climate change. Along some highly populated areas on the shorelines of Hawai'i, wastewater pollution and urban runoff combine with fishing pressures to put immense stress on coral reefs.
