Compounds released by bleaching reefs promote bacteria, potentially stressing coral further      (via sciencedaily.com)     Original source 

New research revealed that when coral bleaching occurs, corals release unique organic compounds into the surrounding water that not only promote bacterial growth overall, but select for opportunistic bacteria that may further stress reefs.

Global deforestation leads to more mercury pollution      (via sciencedaily.com)     Original source 

Researchers find deforestation accounts for about 10 percent of global human-made mercury emissions. While it cannot be the only solution, they suggest reforestation could increase global mercury uptake by about 5 percent.

Innovations in depth from focus/defocus pave the way to more capable computer vision systems      (via sciencedaily.com)     Original source 

In an image, estimating the distance between objects and the camera by using the blur in the images as clue, also known as depth from focus/defocus, is essential in computer vision. However, model-based methods fail when texture-less surfaces are present, and learning-based methods require the same camera settings during training and testing. Now, researchers have come up with an innovative strategy for depth estimation that combines the best of both the worlds to solve these limitations, extending the applicability of depth from focus/defocus.

Researchers show classical computers can keep up with, and surpass, their quantum counterparts      (via sciencedaily.com)     Original source 

A team of scientists has devised means for classical computing to mimic a quantum computing with far fewer resources than previously thought. The scientists' results show that classical computing can be reconfigured to perform faster and more accurate calculations than state-of-the-art quantum computers.

Researchers unveil method to detect 'forever chemicals' in under 3 minutes      (via sciencedaily.com)     Original source 

PFAS have earned the name 'forever chemicals' with good reason -- the human-made compounds, which can take thousands of years to degrade and are found in everything from grease-resistant food packaging to water-repellent clothing, have made their way into nearly half the U.S. tap water supply.

'Legacy' phosphorus delays water quality improvements in Gulf of Mexico      (via sciencedaily.com)     Original source 

The same phosphorus that fertilizes the thriving agriculture of the Midwest is also responsible for a vast 'dead zone' in the Gulf of Mexico near the Mississippi Delta. Efforts to reduce the amount of phosphorus that enters the Mississippi River system are underway, but research suggests that remnants of the contaminant are left behind in riverbeds for years after introduction and pose an overlooked -- and lingering -- problem.

Ancient rocks improve understanding of tectonic activity between earthquakes      (via sciencedaily.com)     Original source 

Rocks once buried deep in ancient subduction zones -- where tectonic plates collide -- could help scientists make better predictions of how these zones behave during the years between major earthquakes, according to a research team.

Replacing animal-based foods with alternative proteins would unlock land for carbon removal      (via sciencedaily.com)     Original source 

Researchers report that replacing 50% of animal products with alternative proteins by 2050 could free up enough agricultural land to generate renewable energy equivalent in volume to today's coal-generated power while simultaneously removing substantial CO2 from the atmosphere.

New study sheds new light on forests' role in climate and water cycle      (via sciencedaily.com)     Original source 

Forests, which cover a third of Earth's land surface, are pivotal in carbon storage and the water cycle, though the full scope of their impact remains to be fully understood. In a new study, researchers provide new insights into the complex role forests play in the climate system and water cycle.

Inexpensive, carbon-neutral biofuels are finally possible      (via sciencedaily.com)     Original source 

When it comes to making fuel from plants, the first step has always been the hardest -- breaking down the plant matter. A new study finds that introducing a simple, renewable chemical to the pretreatment step can finally make next-generation biofuel production both cost-effective and carbon neutral.

New study points to more climate extremes      (via sciencedaily.com)     Original source 

A new study has found similarities between long-term climatic changes in South Australia and temperate agricultural areas in Argentina -- highlighting similarities across these Southern Hemisphere countries. As temperature records tumble, and the threat of bushfires and dry conditions looms large, researchers renew the urgency of calls to make more concerted efforts to prepare for climate extremes in South Australia.

Number of shark bites consistent with recent trends, with small spike in fatalities      (via sciencedaily.com)     Original source 

There was an increase in the number of unprovoked shark attacks worldwide and an uptick in fatalities in 2023 compared to the previous year. A scientific database of global shark attacks, confirmed 69 unprovoked bites in 2023. Although this is higher than the most recent five-year average of 63 attacks, the data remain consistent with long-term trends.

Ammonia attracts the shipping industry, but researchers warn of its risks      (via sciencedaily.com)     Original source 

Switching to ammonia as a marine fuel, with the goal of decarbonization, can instead create entirely new problems. This is shown in a study where researchers carried out life cycle analyses for batteries and for three electrofuels including ammonia. Eutrophication and acidification are some of the environmental problems that can be traced to the use of ammonia -- as well as emissions of laughing gas, which is a very potent greenhouse gas.
