Engineered Secretory Immunoglobulin A provides insights on antibody-based effector mechanisms targeting Clostridiodes difficile

Posted by dbos Hopkins

Kavli Affiliate: Michael Miller | Authors: Sonya Kumar Bharathkar, Michael J. Miller and Beth M. Stadtmueller | Summary: Secretory (S) Immunoglobin (Ig) A is the predominant mucosal antibody, which mediates host interactions with commensal and pathogenic microbes, including Clostridioides difficile. SIgA adopts a polymeric IgA structure that is bound by secretory component (SC). Despite significance, […]

Speed of sound in methane under conditions of planetary interiors

Posted by dbos Stanford

Kavli Affiliate: Peter Graham | First 5 Authors: Thomas G. White, Hannah Poole, Emma E. McBride, Matthew Oliver, Adrien Descamps | Summary: We present direct observations of acoustic waves in warm dense matter. We analyze wave-number- and energy-resolved x-ray spectra taken from warm dense methane created by laser heating a cryogenic liquid jet. X-ray diffraction […]

Constraints on Dark Matter from Dynamical Heating of Stars in Ultrafaint Dwarfs. Part 1: MACHOs and Primordial Black Holes

Posted by dbos Stanford

Kavli Affiliate: Peter W. Graham | First 5 Authors: Peter W. Graham, Harikrishnan Ramani, , , | Summary: We place limits on dark matter made up of compact objects significantly heavier than a solar mass, such as MACHOs or primordial black holes (PBHs). In galaxies, the gas of such objects is generally hotter than the […]

Black holes regulate cold gas accretion in massive galaxies

Posted by dbos Peking

Kavli Affiliate: Luis C. Ho | First 5 Authors: Tao Wang, Ke Xu, Yuxuan Wu, Yong Shi, David Elbaz | Summary: Nearly every massive galaxy contains a supermassive black hole (BH) at its center. For decades, both theory and numerical simulations have indicated that BHs play a central role in regulating the growth and quenching […]

Coherent Self-Interactions of Dark Matter in the Bullet Cluster

Posted by dbos Stanford

Kavli Affiliate: Peter W. Graham | First 5 Authors: Zachary Bogorad, Peter W. Graham, Harikrishnan Ramani, , | Summary: Many models of dark matter include self-interactions beyond gravity. A variety of astrophysical observations have previously been used to place limits on the strength of such self-interactions. However, previous works have generally focused either on short-range […]
