  • An ultraviolet- and carbon-rich environment is needed to explain the bright emission coming from complex organic molecules observed near the midplane of protoplanetary disks. This implies that the gaseous reservoir from which actively forming planets accrete is carbon and organic rich.

  • The detection of complex cyanides in the protoplanetary disk around the young star MWC 480, and the similarity of their abundance ratios to those found in comets, implies that the rich organic chemistry of our solar nebula was not unique.

  • In combination with existing observations and detailed circumstellar models, the detection of hydrogen deuteride emission from the star TW Hydrae implies a circumstellar disk mass of more than 0.05 solar masses, which is enough to form a planetary system like our own.

  • Using JWST, the molecules seen in planetary atmospheres can be traced back to their cold origins in ices formed in dense interstellar clouds, before the onset of star formation, revealing that chemical diversity and complexity is achieved early.

  • Chloromethane (CH3Cl) has been observed towards a low-mass protostar and comet 67P, making it the first organohalogen detected in space. The species was previously considered to be a biomarker, but the authors suggest viable alternative abiotic formation routes.

  • Vascular endothelial growth factors (VEGFs) regulate vascular development during embryogenesis and angiogenesis in the adult. The recently developed cancer treatments that target VEGF receptor activation highlight the clinical relevance of inhibiting VEGF pathways that are exaggerated in pathological angiogenesis.
