Phys.org / HydroGraphNet boosts watershed predictions of daily flow and nitrogen in sparse data regions

Spatially distributed prediction of streamflow and nitrogen (N) export dynamics is essential for precision management of agricultural watersheds. While temporal deep learning models have shown strong basin-scale performance, ...

Phys.org / In Arizona's desert, tiny ants turn into living hygienists, climbing inside bigger ants' mandibles and cleaning them

Ants are known for many things. They fight, bite and sometimes compete for every crumb. We can now possibly add cleaning services to that list, according to a study published in the journal Ecology and Evolution.

Medical Xpress / Overlooked ribosomal DNA may help explain human size differences

Ribosomal RNA (rRNA), made from many copies of ribosomal DNA (rDNA), is the core component that powers ribosomes—protein-building machines in our body. It helps build proteins by linking amino acids together, and can also ...
