Satellites and Small Bodies With ALMA: Insights Into Solar System Formation and Evolution

AGU Advances, Volume 6, Issue 6, December 2025.
Abstract Our understanding of the formation and evolution of planetary systems has made major advances in the past decade. This progress has been driven in large part by the Atacama Large Millimeter/submillimeter Array (ALMA), which has given us an unprecedented view of solar system bodies themselves, and of the structure and chemistry of forming ...

Safety of selective IL‐23p19 inhibitors for the treatment of psoriasis

Journal of the European Academy of Dermatology and Venereology, Volume 33, Issue 9, Page 1676-1684, September 2019., 2019
Abstract Psoriasis is a chronic disease that requires long‐term treatment. Consequently, understanding the safety and tolerability of any potential treatment over time is critical to effective prescribing. The biologic agents currently available for the treatment of psoriasis target a number of different inflammatory cytokines involved in psoriasis ...

Witnessing the birth of a supermassive protostar [PDF]

Monthly Notices of the Royal Astronomical Society, 2016
The detection of $\rm z>6$ quasars reveals the existence of supermassive black holes of a few $\rm 10^9~M_{\odot}$. One of the potential pathways to explain their formation in the infant universe is the so-called direct collapse model which provides massive seeds of $\rm 10^5-10^6~M_{\odot}$.

Interferometric studies of low-mass protostars

, 2011
With the advances in high angular resolution (sub)millimeter observations of lowmass protostars, windows of opportunities are opening up for very detailed studies of the molecular structure of star forming regions on wide range of spatial scales.

Far-infrared CO and H2O emission in intermediate-mass protostars [PDF]

, 2015
Context. Intermediate-mass young stellar objects (YSOs) provide a link to understanding how feedback from shocks and UV radiation scales from low-to high-mass star forming regions. Aims. Our aim is to analyze excitation of CO and H2O in deeply embedded

Physicochemical Constraints on the Abiotic Polymerization of Nucleotides Into RNA

Journal of Geophysical Research: Biogeosciences, Volume 130, Issue 11, November 2025.
Abstract One of the key steps in the origin of life is the polymerization of nucleotides into nucleic acids like RNA. We have quantified the energetic impact of temperature, pressure, and composition on the polymerization of nucleotides into RNA using the Gibbs function. These Gibbs energies have been used to calculate the probability that a nucleotide

Miller and Urey in the Universe: detecting prebiotic molecules in star-forming regions

Revista Brasileira de Ensino de Física
Astronomical observations have revealed that the simple molecules used in the Miller and Urey experiments (H2O, CH4, NH3, and H2), along with methanol, carbon monoxide, and carbon dioxide, among many others, are abundant in solid form in molecular clouds
