A new study using occupancy modeling suggests that dinosaurs in North America were not in long-term decline before the asteroid impact but instead remained widespread until the end of the Cretaceous. The apparent drop in diversity reflects geological and preservation biases in the fossil record rather than a true biological collapse.

Researchers in Korea have developed a spray-drying method that evenly coats lithium-ion battery materials with carbon nanotubes, enabling efficient dry electrode production without toxic solvents. This innovation reduces energy use, increases durability, and boosts energy density, paving the way for greener, higher-performance batteries for electric vehicles and energy storage.

A new study argues that the World Bank’s $2.15 poverty line drastically underestimates global poverty because it measures survival calories rather than access to a nutritious diet. By introducing a Healthy Diet Poverty Line, researchers show that up to 2.9 billion people cannot afford balanced meals, reshaping how poverty and human well-being should be defined.

A study of over 1,000 embryos found that small, already-hatching blastocysts were more likely to be chromosomally normal than large, expanding ones, particularly for women in their mid-to-late 30s. This suggests that visible cues like hatching stage may help guide embryo selection in IVF when genetic testing is unavailable or inconclusive.

A new review highlights growing evidence that periodontal disease contributes to liver inflammation and worse outcomes in cirrhosis and fatty liver disease through the oral–gut–liver axis. The authors argue that integrating dental care into liver clinics could improve patient outcomes and reduce systemic inflammatory burden.

Researchers discovered that fruit fly larvae can detect and navigate using faint electric fields, a behavior called electrotaxis. The study shows that specialized taste neurons in the larval head encode field direction and strength, reusing existing sensory circuits to guide navigation in moist, conductive environments like rotting fruit.

The article reviews how human-driven environmental changes are altering animal movements and distributions, emphasizing the need to predict rather than just describe these patterns. It highlights the distinction between static and dynamic human impacts, the development of mechanistic models, and the role of predictive movement ecology in shaping effective conservation strategies.

A new study shows that when people see their workplace rank, their sense of entitlement shifts: those near the top ask for higher pay while those lower down ask for less. The research highlights how transparency and salient standards reshape perceived deservingness, raising ethical challenges for how organizations design and communicate pay systems.

A nationwide study of over 237,000 ischemic stroke deaths between 1999 and 2020 shows major shifts in where Americans die, with fewer deaths in hospitals and nursing homes and more occurring at home or in hospice. The findings highlight persistent inequities tied to geography and race, a resurgence in stroke mortality linked to chronic conditions, and unequal access to end-of-life care options.

Thomas Chouvenc’s review highlights how termites are spreading globally through modern boating, with yachts acting as uninspected vessels that carry colonies into new cities. These invasive species cause billions in damages, pose ecological and economic threats, and may hybridize into even hardier forms, though citizen science offers hope for early detection.
