For decades, this bias test looked inside minds—now its biggest blind spot is coming into focus

Tropical forests are among the world's most important carbon sinks. A new study by the Technical University of Munich (TUM), the University of Vienna, and Brazil's National Institute for Amazonian Research suggests that even small understory trees can temporarily store more CO₂ as atmospheric CO₂ levels rise. However, their long-term capacity to sequester carbon may be constrained by nutrient limitations, potentially reducing this ability.

An international team of astronomers has employed the Atacama Large Millimeter/submillimeter Array (ALMA) to perform high-resolution observations of the Needle galaxy. Results of the new observational campaign, presented April 15 on the arXiv preprint server, provide more insights into the properties of molecular gas in this galaxy.

From wearable technology to industrial heat recovery, thermoelectric generators which convert waste heat into electricity have an enormous range of potential applications. So far, however, designing high-performing versions of these devices has remained a painstaking task.

A rare dataset collected by instruments at the point where Antarctica's largest ice shelf begins to float reveals ocean processes that drive melting at this critical part of the continent.
