The wildfire season of 2023 was the most destructive ever recorded in Canada and a new study suggests the impact was unprecedented. It found that four of the year's wildfires in mine-impacted areas around Yellowknife, Northwest Territories potentially contributed up to half of the arsenic that wildfires emit globally each year.

A pilot study shows that nanoscopic 3-D imaging of ancient bone not only provides further insight into the changes soft tissues undergo during fossilization, it also has potential as a fast, practical way to determine which specimens are likely candidates for ancient DNA and protein sequence preservation.

Faced with the world's impending freshwater scarcity, researchers turned to solar steam generators, which are emerging as a promising device for seawater desalination. The team sought design inspiration from trees and harnessed the potential of 3D printing. They present technology for producing efficient SSGs for desalination and introduces a novel method for printing functional nanocomposites for multi-jet fusion. Their SSGs were inspired by plant transpiration and are composed of miniature tree-shaped microstructures, forming an efficient, heat-distributing forest.

Trees in the Brazilian Atlantic Forest are migrating in search of more favourable temperatures with species in mountain forests moving uphill to escape rising heat caused by climate change.

Fluids circulating underground change rocks over the course of time. These processes must be taken into account if they are to be used as a climate archive. Researchers have used 380-million-year-old limestones from Hagen-Hohenlimburg to show in detail which climate information is still preserved in the rock.

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.

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.

Switching from a gas stove to an electric induction stove can reduce indoor nitrogen dioxide air pollution, a known health hazard, by more than 50 percent according to new research.

Scientists are bioprinting 3D structures with a material that is a close match for human tissue, paving the way for true biomanufacturing.

An international team of researchers has embedded gold nanorods in hydrogels that can be processed through 3D printing to create structures that contract when exposed to light -- and expand again when the light is removed. Because this expansion and contraction can be performed repeatedly, the 3D-printed structures can serve as remotely controlled actuators.

An international team of researchers has discovered that metallic minerals on the deep-ocean floor produce oxygen -- 13,000 feet below the surface. Discovery challenges long-held assumptions that only photosynthetic organisms generate Earth's oxygen. Minerals at the abyssal seafloor appear to act like geobatteries to produce oxygen in a process that does not require sunlight.

A new study describes a chemical reaction that can convert Styrofoam into a high-value conducting polymer known as PEDOT:PSS. Researchers also noted that the upgraded plastic waste can be successfully incorporated into functional electronic devices, including silicon-based hybrid solar cells and organic electrochemical transistors.

A new ambient-energy-driven membrane that pumps carbon dioxide out of the air has been developed by researchers.

Researchers has revealed the existence of surface concavities on individual crystal grains -- which are the fundamental blocks -- of perovskite thin films, and have unraveled their significant effects on the film properties and reliability. Based on this discovery, the team pioneered a new way of making perovskite solar cells more efficient and stable via a chemo-elimination of these grain surface concavities.

Creating fertilizers from organic waste can help reduce the consumption of fossil fuels and promote sustainable production. One way of doing this is through hydrothermal liquefaction (HTL), which converts biomass into biocrude oil through a high-temperature, high-pressure process. Two studies explore the use of a fungal treatment to convert the leftover wastewater into fertilizer for agricultural crops.

The way oil drops break up at the water's surface means some oil may not get cleaned up after a spill.
