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.

Clarity needed for businesses to achieve greenhouse gas mitigation      (via sciencedaily.com)     Original source 

Despite efforts to mitigate the effects of climate change, companies are not set up for success, due to conflicting national and sectorial targets and differing availability of abatement options, a new study reveals.

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.

Complex tree canopies help forests recover from moderate-severity disturbances      (via sciencedaily.com)     Original source 

Extreme events wipe out entire forests, dramatically eliminating complex ecosystems as well as local communities. Researchers have become quite familiar with such attention-grabbing events over the years. They know less, however, about the more common moderate-severity disturbances, such as relatively small fires, ice storms, and outbreaks of pests or pathogens.

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.

Apex predators not a quick fix for restoring ecosystems      (via sciencedaily.com)     Original source 

An experiment spanning more than two decades has found that removal of apex predators from an ecosystem can create lasting changes that are not reversed after they return -- at least, not for a very long time. The study challenges the commonly held belief that the reintroduction of wolves to Yellowstone National Park restored an ecosystem degraded by their absence.

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.

Microbial division of labor produces higher biofuel yields      (via sciencedaily.com)     Original source 

Scientists have found a way to boost ethanol production via yeast fermentation, a standard method for converting plant sugars into biofuels. Their approach relies on careful timing and a tight division of labor among synthetic yeast strains to yield more ethanol per unit of plant sugars than previous approaches have achieved.

Study challenges the classical view of the origin of the Antarctic Circumpolar Current and warns of its vulnerability      (via sciencedaily.com)     Original source 

The Circumpolar Current works as a regulator of the planet's climate. Its origins were thought to have caused the formation of the permanent ice in Antarctica about 34 million years ago. Now, a study has cast doubt on this theory, and has changed the understanding of how the ice sheet in Antarctic developed in the past, and what this could mean in the future as the planet's climate changes.

Ultra-sensitive lead detector could significantly improve water quality monitoring      (via sciencedaily.com)     Original source 

Engineers have developed an ultra-sensitive sensor made with graphene that can detect extraordinarily low concentrations of lead ions in water. The device achieves a record limit of detection of lead down to the femtomolar range, which is one million times more sensitive than previous technologies.
