HKU Swire Institute of Marine Science launches youth program to cultivate future ocean stewards

The University of Hong Kong
Business Announcement

The Swire Institute of Marine Science (SWIMS) at The University of Hong Kong (HKU) has launched the Exploring Marine Biodiversity: Empowering Youth Ambassadors for Ocean Stewardship programme. Supported by the Environment and Conservation Fund (ECF), the programme immerses local secondary school students in marine science through hands-on training, empowering them as the next generation of ocean stewards.

The Earth formed from local building blocks

ETH Zurich
Peer-Reviewed Publication

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.

Biochar offers climate-smart path to restore dryland soils and fight desertification

Biochar Editorial Office, Shenyang Agricultural University
Peer-Reviewed Publication

A new review highlights how a carbon-rich material made from agricultural waste could help reverse land degradation, boost food production, and strengthen climate resilience in some of the world’s most vulnerable regions.

Study explains Antarctic sea ice growth and sudden decline

Stanford University
Peer-Reviewed Publication

Although climate models predicted Antarctic sea ice would steadily dwindle, its extent grew for decades until 2016. A new study finds the ice finally receded when wind-driven upwelling unleashed warmer, deeper water.

Freezing soils may hold the key to locking away toxic arsenic, new study finds

Biochar Editorial Office, Shenyang Agricultural University
Peer-Reviewed Publication

A new study reveals that seasonal freeze–thaw cycles can dramatically improve the ability of engineered biochar to trap toxic arsenic in contaminated soils, offering a promising strategy for safer agriculture and environmental remediation.

Biochar helps forests fight acid rain by restoring vital soil nitrogen

Biochar Editorial Office, Shenyang Agricultural University
Peer-Reviewed Publication

A new field study reveals that biochar, a carbon-rich material made from plant residues, can significantly restore soil health and nitrogen availability in forests affected by acid rain. The findings highlight a promising, nature-based solution for protecting ecosystems under increasing environmental stress.

Nano-enabled biochar fertilizers help rice grow safer in contaminated soils

Biochar Editorial Office, Shenyang Agricultural University
Peer-Reviewed Publication

A new study reveals that advanced biochar-based fertilizers, especially those enhanced at the nanoscale, can significantly improve rice growth while reducing the uptake of toxic metals such as cadmium and arsenic. The findings offer a promising strategy to address the dual challenge of low fertilizer efficiency and food safety risks in contaminated agricultural soils.
