Scientists have discovered marsupial forelimbs (arms) develop before birth much earlier than previously thought, providing new insights into evolutionary innovation and biology.  

In an innovative gas fermentation process, reducing the concentration of carbon dioxide was found to significantly improve microbial production of the biodegradable plastic, poly[(R)-3-hydroxybutyrate]. Researchers found that hydrogen-oxidizing bacteria grown under safe, nonflammable gas conditions enable more efficient production of biodegradable plastic at lower CO₂ levels. The study provides a promising strategy for sustainable carbon recycling and efficient CO₂ utilization.

A comprehensive Cal Poly study examining North American bird population data reveals that environmental change does not affect all species equally. The research, assessing data collected across North America over nearly 30 years, found that no single environmental factor explained bird population changes across all species. Instead, species responded in highly individualized ways because of their interactions with their environment. While human-caused disturbances such as light pollution and air pollution can negatively affect bird populations, ecological traits can help predict species' sensitivity and forecast how well they will respond to ongoing environmental change. The study also highlights the importance of local conservation action. While climate change and regional air pollution require broad policy solutions, many environmental factors affecting birds can be addressed at the level of cities or counties.

The study, published in Movement Ecology, found that tarpon do not feed randomly across their range. Instead, they rely on distinct "foraging landscapes" that act as fueling stations during migration.

The research suggested that differences in legal knowledge may be linked to broader social change. Younger participants were more likely to assume that stronger legal protections for dogs and owners already existed

Tourism is a growing source of carbon emissions, yet voluntary. This study found that CO₂-based pricing, particularly when environmental costs are presented as visible surcharges rather than discounts, increases tourists' intentions to conserve energy and resources. From a green capitalism perspective, the findings show how market-based price signals can align consumer behavior with sustainability goals while remaining compatible with business interests and existing consumption patterns.

A consortium led by the Institute for Bioengineering of Catalonia (IBEC) developed this approach based on photopharmacology, a technique to reversibly control drug activity with light. The newly developed compounds, called prosthe6, mimic the function of photoreceptor cells, which degenerate in blinding diseases such as age-related macular degeneration (AMD) and retinitis pigmentosa (RP). These photoswitchable molecules show preliminary safety profiles and represent potential drug candidates for restoring vision in patients with degenerative retinal diseases, without the need for genetic manipulation or implanted devices.
