The James Webb Space Telescope Mission
Twenty-six years ago a small committee report, building on earlier studies,
expounded a compelling and poetic vision for the future of astronomy, calling
for an infrared-optimized space telescope with an aperture of at least .
With the support of their governments in the US, Europe, and Canada, 20,000
people realized that vision as the James Webb Space Telescope. A
generation of astronomers will celebrate their accomplishments for the life of
the mission, potentially as long as 20 years, and beyond. This report and the
scientific discoveries that follow are extended thank-you notes to the 20,000
team members. The telescope is working perfectly, with much better image
quality than expected. In this and accompanying papers, we give a brief
history, describe the observatory, outline its objectives and current observing
program, and discuss the inventions and people who made it possible. We cite
detailed reports on the design and the measured performance on orbit.Comment: Accepted by PASP for the special issue on The James Webb Space

International genome-wide meta-analysis identifies new primary biliary cirrhosis risk loci and targetable pathogenic pathways.
Primary biliary cirrhosis (PBC) is a classical autoimmune liver disease for which effective immunomodulatory therapy is lacking. Here we perform meta-analyses of discovery data sets from genome-wide association studies of European subjects (n=2,764 cases and 10,475 controls) followed by validation genotyping in an independent cohort (n=3,716 cases and 4,261 controls). We discover and validate six previously unknown risk loci for PBC (Pcombined<5 × 10(-8)) and used pathway analysis to identify JAK-STAT/IL12/IL27 signalling and cytokine-cytokine pathways, for which relevant therapies exist
Assessment and Reproducibility of Quantitative Structure–Activity Relationship Models by the Nonexpert
Model
reliability is generally assessed and reported as an intrinsic
component of quantitative structure–activity relationship (QSAR)
publications; it can be evaluated using defined quality criteria such
as the Organisation for Economic Cooperation and Development (OECD)
principles for the validation of QSARs. However, less emphasis is
afforded to the assessment of model reproducibility, particularly
by users who may wish to use model outcomes for decision making, but
who are not QSAR experts. In this study we identified a range of QSARs
in the area of absorption, distribution, metabolism, and elimination
(ADME) prediction and assessed their adherence to the OECD principles,
as well as investigating their reproducibility by scientists without
expertise in QSAR. Here, 85 papers were reviewed, reporting over 80
models for 31 ADME-related endpoints. Of these, 12 models were identified
that fulfilled at least 4 of the 5 OECD principles and 3 of these
12 could be readily reproduced. Published QSAR models should aim to
meet a standard level of quality and be clearly communicated, ensuring
their reproducibility, to progress the uptake of the models in both
research and regulatory landscapes. A pragmatic workflow for implementing
published QSAR models and recommendations to modellers, for publishing
models with greater usability, are presented herein
