More colorful songbirds face higher extinction risk‎

In the humid jungle of Vietnam, Natalia Ocampo-Peñuela and Monte Neate-Clegg spent hours patiently waiting to spot the rare "Halloween bird." Officially known as the collared laughingthrush, this songbird has striking orange, silver and black coloring and a distinct, singsong call. It's extremely valuable and heavily traded as a pet in Vietnam, and is considered endangered by the International Union for Conservation of Nature (IUCN).

Mission documents ecosystem interactions of radioactive waste dumped in the Atlantic between 1950 and 1990‎

Between 1950 and 1990, more than 200,000 barrels filled with radioactive waste were dumped in the depths of the North-East Atlantic. Following an initial mission carried out between June 15 and July 11, 2025, to map the area where the barrels were dumped, the Nodssum project, led by the CNRS, set sail again at the end of May 2026. The aim was to explore the areas of interest identified during the first campaign.

Honeybee queens push pesticides to eggs to protect themselves over their offspring, research reveals‎

Worker bees are the first line of defense when it comes to removing contamination in honeybee colonies, but a queen has her ways, too. A honeybee queen facing chronic exposure to pesticides will take up that contamination and pass it along to her eggs, a process researchers call maternal offloading.

Rethinking the governance of human embryo research: Comparing Japan's guidelines with international standards‎

Human embryo models can help researchers study early human development and infertility without relying solely on human embryos. As the technology advances, these models are becoming more complex and can be maintained in culture for longer periods. These developments have raised new questions about how such research should be regulated.

How heat stress triggers emergency programs in plants‎

Researchers at the Karlsruhe Institute of Technology (KIT) have found how plant cells respond to stress. If their energy supply is disrupted by heat, drought or saline soils, chloroplasts—the cells' powerhouses—send an intracellular distress signal by forming tiny, finger-like projections. This signal specifically activates protection programs that help limit damage. The study, published in Plant Physiology, reveals the function of these previously mysterious structures and presents an approach for making crops more resilient to climate stress.

Scourge of satellites lighting up the sky could be mitigated with help of ultra-black coating‎

Astrophysicists working to tackle the growing impact of satellite constellations have pioneered a new ultra-black coating as one possible way to mitigate the problem.

A holoparasitic plant replaces its own genes with host DNA to survive‎

All living organisms are known to inherit genes, DNA sequences that contain instructions for producing specific proteins and performing biological functions, from their parents. In some cases, however, genes can also shift between different species via a process known as horizontal gene transfer (HGT).

Enriching conversations with toddlers‎

Asking open-ended questions and weaving conversations into everyday activities helps toddlers' communication skills, new research shows. Three recently published University of Otago–Ōtākou Whakaihu Waka studies analyzed the outcomes of the Enhancing Rich Interactions (ENRICH) program, which provides early childhood educators with tools and techniques to help improve toddlers' language, literacy and social skills. Using parent and teacher ratings and video analysis, researchers found the program had a positive impact on toddlers' oral language.

Quantum semiconductor design could expand search for dark matter‎

Dark matter accounts for 85% of the matter in the universe, but scientists still do not know what it is made of. A study, published in Physical Review Letters, by Rice University researchers proposes a detector design that could help search for axions, hypothetical particles that many physicists think could make up dark matter.
