How to make farms tree-friendly and boost food production‎

Farmers could turn more of the UK's farmland into productive agroforestry systems if they had access to trusted advice and real farm examples, according to new research from the University of Reading. Dr. Amelia Hood, from the Department of Sustainable Land Management at the University of Reading, worked with 220 stakeholders including farmers, policymakers and NGOs to identify why agroforestry is still rare in the UK, despite strong interest from farmers and government funding for tree planting.

Study warns Colombia could lose one-fifth of cocoa land by 2050‎

By 2050, nearly 20% of the areas currently suitable for cocoa cultivation in Colombia could lose the climate conditions needed for production, particularly in the lowlands of the Caribbean region and the country's northeastern departments, according to a new scientific study.

Evaluating landing sites for China's manned moon mission‎

Observations of the Rimae Bode region on the moon reveal five distinct types of terrain and identify several potential landing sites for China's first crewed mission, according to research titled "Geology of Rimae Bode region as priority site candidate for China's first crewed lunar mission." The work is published in Nature Astronomy.

Raccoons solve puzzles for the fun of it, new study finds‎

They raid compost bins, outsmart latches and sometimes look gleeful doing it. A new study in Animal Behaviour suggests raccoons may not just be opportunistic—they may be genuinely curious.

How do we know what asteroids are made out of?‎

Asteroids are some of the oldest objects in the solar system: leftovers from the chaotic time when planets were assembling from dust and rock. They're time capsules, preserving clues about what the early solar system was like, and, ultimately, what the building blocks of planets are.

U.S. Indigenous peoples experience higher rates of fatal police violence in and around reservations‎

Indigenous people in the United States are at higher risk of fatal police violence in and around American Indian/Alaska Native (AIAN) reservations, according to the first comprehensive national study on the subject from researchers at Drexel University's Dornsife School of Public Health and the University of Washington. The study, using data on the 203 AIAN people killed by police from 2013 through 2024, is published in the Proceedings of the National Academy of Sciences. The authors hope this work will inform policy action to better protect these communities.

Gene edit makes probiotic safer for immunocompromised patients‎

An international team of researchers has modified a probiotic yeast to make it safer for use by immunocompromised people, older adults and infants. Testing in an animal model found that the modified yeast is less likely to cause infection than unmodified strains of the same organism. The associated research paper is published in the journal Communications Biology.

How AI could unlock deep‑sea secrets of marine life‎

Somewhere in the North Atlantic, more than a kilometer beneath its surface, a cold-water coral reef stretches across an unnamed seamount. Despite never appearing on a chart, this underwater forest has existed for centuries, growing a centimeter or two each year.

Physical activity is linked to the health of the planet, according to a trio of recent studies‎

Global levels of physical activity have not improved over the past two decades, despite widespread policy development and adoption, and large disparities persist across gender and socioeconomic groups. The findings from three papers published in Nature Medicine and Nature Health indicate that current efforts to promote participation in physical activity are insufficient and that coordinated action is needed to ensure that physical activity contributes to public health and wider societal goals, including climate resilience.

In search of a room-temperature superconductor, scientists present a research agenda‎

The search for materials that can conduct electricity at room temperature without losing energy is one of the greatest and most consequential challenges of modern physics: loss-free power transmission, more efficient motors and generators, more powerful quantum computers, cheaper MRI devices. Hardly any other material discovery has the potential to change so many areas of technology and everyday life at the same time.
