The \emph{JWST} Emission Line Survey (JELS): The sizes and merger fraction of star-forming galaxies during the Epoch of Reionization

We used observations from the \emph{JWST} Emission Line Survey (JELS) to measure the half-light radii ($r_{e}$) of 23 H$α$-emitting star-forming (SF) galaxies at $z=6.1$ in the PRIMER/COSMOS field. Ga...

White fruits are relatively rare in plants. Birds don’t detect them very well because they have low chromatic contrast with background vegetation. Mammals can more easily detect white fruits if they are aromatic, like this stinky Morinda citrifolia #dispersal #Rubiaceae #Botany 🌾🧪🌱

Friday Flower 007: Petunia 💮✨

Petunias carry the active transposon dTph1, which powers mutant screens and paints stripey patterns as it jumps.

Their five petals are fused, with diverse color designs tracing the corolla’s fusion seam.
