After 40 years of extinct status in South Australia, the Murray crayfish is back! Darren Willis speaks about Glen, who shared the cultural significance of the project to First Nations peoples in the area, on day 2 of #ESA2025.

It's never occurred to me that it IS an assumption. This is the most astonishing start to a paper I've read in years:
"Living organisms are assumed to produce same-species offspring. Here, we report a shift from this norm in Messor ibericus, an ant that lays individuals from two distinct species."
"Living organisms are assumed to produce same-species offspring. Here, we report a shift from this norm in Messor ibericus, an ant that lays individuals from two distinct species."
One mother for two species via obligate cross-species cloning in ants - Nature
In a case of obligate cross-species cloning, female ants of Messor ibericus need to clone males of Messor structor to obtain sperm for producing the worker caste, resulting in males from the same mother having distinct genomes and morphologies.

Since 2015, freshwater loss from land — mainly from pumping groundwater — has contributed more to sea level rise than melt from Antarctic ice sheet. 🧪
We're undergoing an unprecedented loss of freshwater across the planet
Rising temperatures are causing water to evaporate and driving humans to extract more groundwater, which is moving freshwater from the land to the seas and creating a "continental drying" trend
