Forests are falling behind in the race against climate change, with new research revealing it takes centuries for tree populations to adapt—far too slow to keep pace with today’s rapidly warming world.

Scientists have conducted a study of the predatory behavior of sharks in deep-sea ecosystems. This research provides insights into the behavior and distribution range of Pacific sleeper sharks. The research is published in the journal Ocean-Land-Atmosphere Research on June 1, 2025.

The origin of life is one of the most fundamental and enduring questions of mankind and one of the three greatest Origin Questions in the natural sciences.  Recently, China has officially launched its Mars Sample Return (MSR) mission, Tianwen-3, marking a significant step forward in planetary exploration. The mission aims to bring Martian samples back to Earth, where advanced laboratory instruments will be employed to conduct comprehensive analyses, seeking to determine whether life ever existed—or may still exist—on Mars. Professor Yiliang LI, an astrobiologist from the Department of Earth Sciences at The University of Hong Kong (HKU), serves as a core member of the Tianwen-3 scientific team and a co-author of a recently published perspective article in Nature Astronomy outlining the mission’s objectives. His role mainly involves leading an HKU group that is working on the selection of the landing site for the Tianwen-3 MSR mission.

If humans are ever going to live beyond Earth, they’ll need to construct habitats. But transporting enough industrial material to create livable spaces would be incredibly challenging and expensive. Harvard researchers think there's a better way, through biology. 

An international team of researchers led by Robin Wordsworth have demonstrated that they can grow green algae inside shelters made out of bioplastics in Mars-like conditions. The experiments are a first step toward designing sustainable habitats in space that won’t require bringing materials from Earth.

A new analysis suggests that reductions in U.S. military spending could result in significant decreases in energy consumption by the Department of Defense, leading to reduced greenhouse gas emissions. Ryan Thombs of Penn State University, U.S., and colleagues present these findings in the open-access journal PLOS Climate on July 2.

Common carp which are reared in fish-farms, stocked into recreational fisheries and then captured regularly by catch-and-release angling show much lower chronic stress levels than their wild counterparts that never see an angler’s hook, a new study has found.
