Researchers have developed a new brain–computer interface that records neural signals from the brain’s lateral ventricle, a fluid-filled cavity traditionally used only for clinical drainage. Using a lantern-inspired expandable electrode, the system delivers stable, high-quality recordings for months and decodes memory-guided decisions with up to 98% accuracy in rats. The approach reduces immune response compared with conventional cortical implants and opens a new route for long-term, minimally invasive brain–machine interfaces.

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.

Researchers have engineered an innovative solution that simultaneously addresses two significant environmental problems: the pervasive threat of emerging contaminants in water and the challenge of agricultural waste management. A team at Guangzhou University has successfully converted chicken manure, a widespread livestock byproduct, into a powerful catalyst capable of rapidly purifying contaminated water. This novel approach provides an eco-friendly and resource-efficient method for environmental remediation.

A new investigation reveals the significant potential of hydrochars, derived from common biowastes like sewage sludge and chicken manure, to function as effective slow-release phosphorus fertilizers. These findings offer a dual advantage for agriculture: enhancing crop productivity while simultaneously addressing challenges of waste management and environmental sustainability. Traditional phosphorus fertilizers often contribute to nutrient leaching and water pollution, prompting a global search for more environmentally sound solutions. This research presents a compelling case for hydrochars as a promising pathway toward a regenerative agricultural system.

Scientists have successfully tested eco-friendly plastic plates as a potential replacement for the steel bars traditionally used to reinforce concrete. Their findings could help drive the development of more sustainable materials while enabling the mass production of innovative reinforcing shapes. The research also highlights that the performance of reinforced concrete depends not only on the material itself but also on the geometry of reinforcement.
