Researchers reveal there are an estimated 400 billion microplastic fibers on the surface of Frenchman Bay, which borders Bar Harbor and Acadia National Park in Maine, and several connected rivers and estuaries where freshwater from rivers meet salty seawater. The watershed contains an average of 1.8 fibers per liter of water. The team also investigated how microplastics traveled throughout the watershed by sampling water from nine sites on Mount Desert Island, particularly within Bar Harbor.

According to new research subsurface reservoirs that are covered by a collection of hundreds of smaller lids -- collectively called a 'composite confining system' -- may be the better option for keeping carbon trapped for the long term. That's good news for the carbon storage industry. This type of distributed system is common in a range of geological environments.

A room-temperature method to decompose perfluoroalkyl substances (PFASs) using visible LED light offers a promising solution for sustainable fluorine recycling and PFAS treatment.

A new analysis sheds light on major shortfalls of a recently proposed approach to capture CO2 from air and directly convert it to fuel using electricity. The authors also provide a new, more sustainable, alternative.

In blockchain development, there is a rule of thumb that only two of scalability, security, and decentralization are valid simultaneously. However, the mathematical expression of that rule was still a work in progress. Researchers discovered a mathematical expression for the blockchain trilemma. In the formula for Proof of Work-based blockchains, including Bitcoin, the product of the three terms--scalability, security, and decentralization--is 1.

Researchers have made an exciting discovery on the Hong Kong coast. They have identified two fiddler crab species: Tubuca dussumieri, previously recorded in old literature but never confirmed in recent times, and Tubuca. coarctata, which has never been seen in Hong Kong. These findings not only confirm the presence of these insular species in Hong Kong but also explore the potential impact of climate change on their distribution.

When water is split electrolytically, the result is typically hydrogen -- and 'useless' oxygen. Instead of oxygen, you can also produce hydrogen peroxide, which is required for many branches of industry. This, however, requires certain reaction conditions.

Some species of fish can evolve their egg-laying habits in response to predators in the area in order to survive, according to new research.

As the number of major utility-scale ground solar panel installations grows, concerns about their impacts on natural hydrologic processes also have grown. However, a new study by Penn State researchers suggests that excess runoff or increased erosion can be easily mitigated -- if these 'solar farms' are properly built.

An environmental engineering team has discovered that specific bacterial species can cleave the strong fluorine-to-carbon bond certain kinds of 'forever chemical' water pollutants, offering promise for low-cost treatments of contaminated drinking water.

When it comes to diatoms that live in the ocean, new research suggests that photosynthesis is not the only strategy for accumulating carbon. Instead, these single-celled plankton are also building biomass by feeding directly on organic carbon in wide swaths of the ocean. These new findings could lead to reduced estimates regarding how much carbon dioxide diatoms pull out of the air via photosynthesis, which in turn, could alter our understanding of the global carbon cycle, which is especially relevant given the changing climate.

Australian engineers have unveiled a clever new device -- based on a modified speargun -- as a cheap and efficient way to test seabed soil when designing offshore wind farms.
