Molecular Drivers of RNA Phase Separation

Kavli Affiliate: V. S. Ramachandran | Authors: Marc Turner, Sarah Robinson-Schwartz, Siavash Fazel Darbandi, John L.R. Rubenstein and Vikaas Singh Sohal | Summary: RNA molecules are essential in orchestrating the assembly of biomolecular condensates and membraneless compartments in cells. Many condensates form via the association of RNA with proteins containing specific RNA binding motifs. However, […]

Mef2c Controls Postnatal Callosal Axon Targeting by Regulating Sensitivity to Ephrin Repulsion

Kavli Affiliate: Alex Kolodkin | Authors: Sriram Sudarsanam, Luis Guzman-Clavel, Nyle Dar, Jakub Ziak, Naseer Shahid, Xinyu O Jin and Alex L Kolodkin | Summary: Cortical connectivity is contingent on ordered emergence of neuron subtypes followed by the formation of subtype-specific axon projections. Intracortical circuits, including long-range callosal projections, are crucial for information processing, but […]

Loss of the autism associated gene Tbr1 disrupts prediction and encoding by prefrontal ensembles during socioemotional behaviors

Kavli Affiliate: John Rubenstein and Vikaas Sohal | Authors: Marc Turner, Sarah Robinson-Schwartz, Siavash Fazel Darbandi, John L.R. Rubenstein and Vikaas Singh Sohal | Summary: Disruptions in many genes linked to autism spectrum disorder (ASD) affect synaptic function and socioemotional behaviors in mice. However, exactly how synaptic dysfunction alters neural activity patterns underlying behavior remains […]

Non-equilibrium ionization in the multiphase circumgalactic medium — impact on quasar absorption-line analyses

Kavli Affiliate: Hsiaowen Chen |Summary:This paper presents an updated framework for studying the ionizing conditions and elemental abundances of photoionized, metal-enriched quasar absorption systems. The standard assumption of ionization equilibrium invoked in absorption line analyses requires gas to cool on longer timescales than ionic recombination (t_cool >> t_rec). However, this assumption may not be valid […]

BlackTHUNDER — A non-stellar Balmer break in a black hole-dominated little red dot at $z=7.04$

Kavli Affiliate: Debora Sijacki | Summary:Recent observations from JWST have revealed an abundant population of active galactic nuclei (AGN) and so-called “Little Red Dots” (LRDs) at $2lesssim z lesssim 11$, many of which are characterized by V-shaped UV-to-optical continua with turnovers around the Balmer limit. The physical nature of these LRDs is unclear, and it […]

On the equivalence between galaxy angular correlation function and power spectrum in constraining primordial non-Gaussianity

Kavli Affiliate: Masahiro Takada | Summary:We investigate the angular power spectrum ($C_ell)$ and angular correlation function ($w(θ)$) of galaxy number density field in the presence of the local-type primordial non-Gaussianity (PNG), explicitly accounting for the integral constraint in an all-sky survey. We show that the PNG signature in $C_ell$ is confined to low multipoles in […]
