The multi planet system HR8799 is the first target observed with MIRI's coronagraphs as part of the MIRI-EC Guaranteed Time Observations exoplanets programme in Nov. 2022. We obtained deep observations in three coronagraphic filters from 10 to 15mic

By using an ultradeep JWST/MIRI image at 5.6 μ m in the Hubble eXtreme Deep Field, we constrain the role of strong H α emitters (HAEs) during “cosmic reionization” at z ≃ 7–8. Our sample of HAEs is comprised of young (

The competitive dynamics of mitochondrial haplotypes juxtaposed within the same cell are poorly studied. Here the authors show, in the context of a transmissible cancer, that one haplotype has recurrently entered cancer cells by horizontal transfer a
