1. MINDS. Hydrocarbons detected by JWST/MIRI in the inner disk of Sz28 consistent with a high C/O gas-phase chemistry 

   Kanwar J.; Kamp I.; Jang H.; et al. (2024)

   Astronomy & Astrophysics

   Context. With the advent of JWST, we are acquiring unprecedented insights into the physical and chemical structure of the inner regions of planet-forming disks where terrestrial planet formation occurs. Very low-mass stars (VLMSs) are known to have a high occurrence of the terrestrial planets orbiting them. Exploring the chemical composition of the gas in these inner disk regions can help us better understand the connection between ...

2. Effect of depolarizing field on domain structure of an improper ferroelectric 

   Müller A.M.; Bortis A.; Simonov A.; et al. (2024)

   Physical Review B

   We show that, contrary to common belief, the depolarizing electric field generated by bound charges at thin-film surfaces can have a substantial impact on the domain structure of an improper ferroelectric with topological defects. In hexagonal-manganite thin films, we observe in phase-field simulations that through the action of the depolarizing field, (1) the average magnitude of the polarization decreases, (2) the local magnitude of the ...

3. Performance of the CMS electromagnetic calorimeter in pp collisions at √<inf>s</inf> = 13 TeV 

   Hayrapetyan A.; Tumasyan A.; Adam W.; et al. (2024)

   Journal of Instrumentation

   The operation and performance of the Compact Muon Solenoid (CMS) electromagnetic calorimeter (ECAL) are presented, based on data collected in pp collisions at √s = 13 TeV at the CERN LHC, in the years from 2015 to 2018 (LHC Run 2), corresponding to an integrated luminosity of 151 fb-1. The CMS ECAL is a scintillating lead-tungstate crystal calorimeter, with a silicon strip preshower detector in the forward region that provides precise ...

4. Metabolic interdependencies in thermophilic communities are revealed using co-occurrence and complementarity networks 

   Peng X.; Wang S.; Wang M.; et al. (2024)

   Nature Communications

   Microbial communities exhibit intricate interactions underpinned by metabolic dependencies. To elucidate these dependencies, we present a workflow utilizing random matrix theory on metagenome-assembled genomes to construct co-occurrence and metabolic complementarity networks. We apply this approach to a temperature gradient hot spring, unraveling the interplay between thermal stress and metabolic cooperation. Our analysis reveals an ...

5. Nutritional vitamin B12 regulates RAS/MAPK-mediated cell fate decisions through one-carbon metabolism 

   Laranjeira A.C.; Berger S.; Kohlbrenner T.; et al. (2024)

   Nature Communications

   Vitamin B12 is an essential nutritional co-factor for the folate and methionine cycles, which together constitute one-carbon metabolism. Here, we show that dietary uptake of vitamin B12 modulates cell fate decisions controlled by the conserved RAS/MAPK signaling pathway in C. elegans. A bacterial diet rich in vitamin B12 increases vulval induction, germ cell apoptosis and oocyte differentiation. These effects are mediated by different ...
