Iberian harvester ant queens are cloning different species to produce hybrid workers
This new frontier in reproduction is referred to by the authors as "xenoparous," meaning the ant queens have a need to produce individuals of another species as an inherent part of their life cycle. The exact developmental mechanism of cross-species male cloning is still unknown, but the authors have some theories.

Tähdet ja avaruus: Harvinainen ilmiö: Kuu muuttuu sunnuntaina punaiseksi
[Pimennys] alkaa kello 20.31. Kuu on tuolloin itäkaakossa ja erittäin matalalla horisontissa. Pimennystä seuraavien kannattaakin hakeutua sellaiselle korkealle havaintopaikalle, jossa näkyvyys itäkaakon puoleiseen horisonttiin on hyvä, eikä edessä ole taloja, puita tai muita esteitä.
Täydellisen pimennyksen syvin hetki koetaan kello 21.12.

Päiväaktiivisten yöperhosten suuremmat kuuloelimet kyseenalaistavat olettamukset niiden evoluutiosta | Helsingin yliopisto
Tutkijat tekivät odottamattoman löydön: päiväaktiivisilla yöperhosilla on suuremmat korvat kuin niiden yöaktiivisilla sukulaisilla. Havainto on yllättävä, koska päiväaktiiviset lajit eivät joudu kaikuluotaavien lepakoiden saalistamiksi.

(The news article, and to a lesser degree the study’s abstract imply females being more aggressive rather than self-reporting being so, which is what the study actually discovered.)
Females show higher sibling-specific aggression than males, study finds
In terms of direct aggression, girls and women [reported being] slightly more aggressive towards their siblings [than] boys and men. Men and boys, by contrast, [reported being] more likely to be directly aggressive with non-siblings.

(Earlier: Why the UK’s butterflies are booming in 2025)
Why are we seeing so many butterflies in Ireland this year?
Another reason for the 2025 butterfly boom is the weather in Europe. Hot, dry weather creates drought, and butterflies capable of migration escape by altitudinal and geographical migration. By moving north, Clouded Yellow, Large White, Small White, Red Admiral and Painted Lady butterflies can find succulent foodplants for their caterpillars.

Global inequality is huge — but so is the opportunity for people in high-income countries to support poor people
When we think of global inequality, it's easy to picture “the rich” as someone else — those with garages full of sports cars or taking private trips to space. But the richest tenth of the world includes us and likely many others who don’t intuitively think of themselves as “the rich”.
