Largest genetic survey to date shows major success of giant panda breeding programs

A comprehensive genetic survey of captive giant pandas reveals high levels of diversity and low inbreeding rates, indicating a healthy population. The study's findings suggest that captive breeding centers can successfully release pandas into the wild with proper selection criteria.

When is a molecule a molecule?

Scientists observe electrons jumping between molecular fragments up to a distance of about 20 Ångström, marking the transition from molecular to atomic regimes. The study provides insights into charge transfer mechanisms that play a role in numerous chemical processes, including photosynthesis and solar cells.

Research reveals a gender gap in the nation's biology labs

A new study found that women are greatly underrepresented in the labs of high-achieving male biology professors, despite being overrepresented overall. This discrepancy may be due to self-selection or unconscious bias, and institutions can take steps to address these issues by making their labs more welcoming to female scientists.

Scientists reveal new picture in the evolution of flightless birds

A recent study assembled a large dataset using ancient moa DNA and found convincing evidence that tinamous are closely related to extinct moas, leading to independent loss of flight. Morphological characters of ratites were mostly convergent, evolving independently as adaptations to a cursorial lifestyle.

New analysis of 7 ant genomes reveals clues to longer life spans associated with sociality

Researchers identified 24 functional categories of genes with strong positive selection in ant lineages, including those related to nervous system development and immunity. Ant-specific signals on mitochondrial activity genes may be responsible for increased queen lifespan up to 30 years.
