What if the earliest signs of skin cancer could be identified sooner — before a dermatology appointment?

Researchers at the University of Missouri are exploring how artificial intelligence could help detect melanoma — the most dangerous form of skin cancer — by evaluating images of suspicious skin abnormalities.

The diversity of water strider species apparently developed as early as the Cretaceous period, much earlier than previously thought. SNSB researchers have succeeded in clarifying the phylogenetic history of this insect family, with molecular analyses providing comprehensive insights into their relationships and evolution. The study has now been published in the journal Systematic Entomology.

A new study by researchers in Japan offers new insights into how protocells may have inherited and enriched genetic material before modern biology emerged. By exposing mixed phospholipid vesicles to repeated freezing and thawing, the team found that vesicles with more unsaturated lipids grew more efficiently and became selectively enriched. This membrane-level selection also increased the fraction of selectively neutral genetic material trapped inside.

In the icy waters of Alaska’s Bristol Bay, beluga whales rely on an unexpected survival strategy: sharing mates over many years. Long-term genetic and behavioral research reveals a polygynandrous system where both males and females spread reproductive opportunities, creating networks of half-siblings. This approach boosts genetic diversity, reduces inbreeding, and protects the population from genetic drift – showcasing how cooperation, choice, and time help sustain resilience in a small, isolated whale community.
