Bees are particularly affected by high temperatures and more intensive land use, new research reveals
The bees sleep in artificial nests made with stalks of re for preferred flight conditions. Different species close the nest entrance with clay or plant debris. Credit: Christina Ganuza The number and diversity of insects is declining worldwide. Some studies suggest that their biomass has been nearly half since the 1970s. Among the main reasons for this are habitat losses…

Sex Chromosome Fight: How Competition Is Affected X vs Y Sperm Fitness
SLXL1/SLX/SLY1/SLY2 does not interact with other spindolins. Credit: Proceedings of the National Academy of Sciences (2025). doi:10.1073/pnas.2421446122 Evolutionarily, fitness is defined as the ability of an organism to survive and replicate that gene for the next generation. Genes affect fitness and sometimes compete with each other within organisms. This competition, or weapons competition, is usually difficult to observe when the…

Research investigating how climate change has affected coastal forests over the past 10 years
Map of changes between sampling intervals in forested areas in low-elevation and mid-elevation (cross) counties created from FIA. Credit: PLOS Climate (2025). DOI: 10.1371/journal.pclm.0000444 A new study finds that climate change may have contrasting effects on coastal forests, slowing or enabling growth in areas where sea levels rise and storms occur more frequently. The researchers looked at 10 years of…

Scientists identify 11 genes affected by PFAS, shedding light on neurotoxicity
Research led by the labs of University at Buffalo chemistry professors G. Ekin Atilla-Gokcumen and Diana Aga reveals molecular insights into the neurotoxic effects of perfluorinated and polyfluorinated alkyl substances, better known as eternal chemicals. Some clues have been revealed. Credit: Meredith Forrest Kulwicki / University at Buffalo Perfluorinated and polyfluorinated alkyl substances (PFAS) persist in water, soil, and even…

Researchers find grazing zooplankton severely affected by nanoplastic particles
Contrasting responses between phytoplankton taxa to nanoplastic particles and zooplankton ingestion. Credit: Communications Earth & Environment (2024). DOI: 10.1038/s43247-024-01646-7 Researchers from Lund University in Sweden have been studying how nanoplastics affect aquatic life in lakes and rivers. Their findings are surprising: for the first time, they have shown that while some species are becoming extinct, others, such as cyanobacteria that…
