The chemical composition of meteorites and asteroids acts as a kind of fingerprint, providing information about the origin of the building materials that formed the Earth. 

Using a new analysis of existing data, the researchers show that this material must exclusively come from the inner solar system. 

The material that formed the Earth is similar to that found on Mars and the asteroid Vesta. The Earth is thus part of a trend line extending from the Sun. 

This close relationship also enables predictions to be made about the composition of Venus and Mercury, from which we have no known samples. 

A team of researchers led by scientists at Beijing Normal University has conducted a detailed evaluation of China's major ecological engineering projects, quantifying their distinct contributions to enhancing the nation's terrestrial carbon sinks. The findings, published in Carbon Research, provide a nuanced look at the effectiveness of these large-scale environmental initiatives, revealing that success is highly dependent on regional context and project design. This work offers vital information for optimizing ecosystem management as China progresses toward its 2060 carbon neutrality target.

A sweeping new analysis connects two of the planet's most pressing environmental crises, revealing that pervasive microplastic pollution is a significant and overlooked contributor to climate change. The review, led by researchers Kui Li and Hua Wang from the Agricultural University of Hunan, synthesizes a growing body of evidence showing that these tiny plastic fragments not only release greenhouse gases as they degrade but also disrupt natural processes that are vital for storing carbon. This intricate relationship suggests that tackling plastic pollution is essential for climate mitigation efforts.
