In the crowded urban landscape, where small electric vehicles -- primarily scooters and bicycles -- have transformed short distance travel, researchers are reporting a major national surge in accidents tied to 'micromobility.'

Researchers analyzed the financial and environmental costs and benefits of four biofuels crops used to produce sustainable aviation fuels in the U.S. They found that each feedstock -- corn stover, energy sorghum, miscanthus or switchgrass -- performed best in a specific region of the rainfed United States. Their study will help growers and policymakers select the feedstocks most suited to meeting goals like reducing production costs, lowering greenhouse gas emissions and building soil carbon stocks.

World leaders must take advantage of a pivotal window of opportunity for forging a much-needed joined-up approach to tackle climate change and biodiversity loss, say scientists. Without this, work on tackling either crisis could inadvertently harm progress on the other.

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.

New research has revealed critical insights into how strategic emission cap choices can lead to cost-effective, near-100% ammonia industry decarbonization while avoiding issues such as land use constraints and grid congestion.

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.

The combined effect of environmental exposures and unhealthy lifestyle habits can affect children's cardiometabolic health in a way that exceeds their separate effects. A new study shows the benefit of measuring the combined effect of multiple environmental and lifestyle factors.

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.

Two-dimensional (2D) materials have atomic-level thickness and excellent mechanical and physical properties, with broad application prospects in fields such as semiconductors, flexible devices, and composite materials.

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.

Climate change will have a considerable influence on the biodiversity and productivity of meadows and pastures. However, according to the results of the large-scale climate and land use experiment the extent of these changes depends on the land use. Grassland optimized for high yield responds much more sensitively to periods of drought than less intensively used meadows and pastures.

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.

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.
