Neural signatures of stress susceptibility and resilience in the amygdala-hippocampal network

Posted by dbos October 23, 2023November 6, 2023Columbia

Kavli Affiliate: Stefano Fusi & Mazen Kheirbek | Authors: Frances Xia, Valeria Fascianelli, Nina Vishwakarma, Frances Grace Ghinger, Stefano Fusi and Mazen Kheirbek | Summary: The neural dynamics that underlie divergent anhedonic responses to stress remain unclear. Here, we identified neuronal dynamics in an amygdala-hippocampal circuit that distinguish stress resilience and susceptibility. In a reward-choice […]

Host–pathogen–vector continuum in a changing landscape: Drivers of Bartonella prevalence and evidence of historic spillover in a multi–host community

Posted by dbos October 23, 2023November 6, 2023UCSD / Salk

Kavli Affiliate: V. S. Ramachandran | Authors: B.R. Ansil, Ashwin Viswanathan, Vivek Ramachandran, H.M. Yeshwanth, Avirup Sanyal and Uma Ramakrishnan | Summary: Small mammals and their ectoparasites present a unique system to investigate the eco-epidemiology of multi-host vector-borne pathogens and identify specific bacterial spillover determinants. We applied ecological and evolutionary analyses in a rainforest-human-use mosaic […]

LET-381/FoxF and UNC-30/Pitx2 control the development of C. elegans mesodermal glia that regulate motor behavior.

Posted by dbos October 23, 2023November 6, 2023Rockefeller

Kavli Affiliate: Shai Shaham | Authors: Nikolaos Stefanakis, Jessica Jiang, Yupu Liang and Shai Shaham | Summary: While most CNS glia arise from neuroectodermal progenitors, some, like microglia, are mesodermally derived. To understand mesodermal glia development and function, we investigated C. elegans GLR glia, which ensheath the brain neuropil and separate it from the circulatory-system […]

Kavli Affiliate: Michael Miller | Authors: David A. Alvarado, Luis Alberto Ibarra-Sanchez, Annemarie R. Mysonhimer, Tauseef A Khan, Rong Cao, Michael J. Miller and Hannah Holscher | Summary: Background Bifidobacterium animalis ssp. lactis DN-173 010/CNCM I-2494 (B. animalis) is a probiotic strain commonly added to yogurt. Yogurt and honey are a popular culinary pairing. Honey […]

Context-invariant socioemotional encoding by prefrontal ensembles

Posted by dbos October 23, 2023November 6, 2023UCSF

Kavli Affiliate: Vikaas Sohal | Authors: Nicholas A Frost, Kevin C Donohue and Vikaas Sohal | Summary: The prefrontal cortex plays a key role in social interactions, anxiety-related avoidance, and flexible context- dependent behaviors, raising the question: how do prefrontal neurons represent socioemotional information across different environments? Are contextual and socioemotional representations segregated or intermixed, […]

Field-level simulation-based inference with galaxy catalogs: the impact of systematic effects

Posted by dbos October 23, 2023MIT

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Natalí S. M. de Santi, Francisco Villaescusa-Navarro, L. Raul Abramo, Helen Shao, Lucia A. Perez | Summary: It has been recently shown that a powerful way to constrain cosmological parameters from galaxy redshift surveys is to train graph neural networks to perform field-level likelihood-free inference without imposing […]

Posted by October 23, 2023Chicago

Kavli Affiliate: Nickolay Y. Gnedin | First 5 Authors: Alexandra Wells, David Robinson, Camille Avestruz, Nickolay Y. Gnedin, | Summary: We examine the evolution of the phase diagram of the low-density intergalactic medium during the Epoch of Reionization in simulation boxes with varying reionization histories from the Cosmic Reionization on Computers project. The PDF of […]

Separated twins or just siblings? A multi-planet system around an M dwarf including a cool sub-Neptune

Posted by klaurent October 23, 2023MIT

Kavli Affiliate: Roland Vanderspek | Summary:We report the discovery of two TESS sub-Neptunes orbiting the early M dwarf TOI-904 (TIC 261257684). Both exoplanets, TOI-904 b and c, were initially observed in TESS Sector 12 with twin sizes of $2.426_-0.157^+0.163$ and $2.167_-0.118^+0.130$ R$_oplus$, respectively. Through observations in five additional sectors in the TESS primary mission and […]
