Standing genetic variation and chromosome differences drove rapid ecotype formation in a major malaria vector

Posted by klaurent Columbia

Kavli Affiliate: Scott Small | Authors: Scott T Small, Carlo Costantini, N’Fale Sagnon, Moussa W Guelbeogo, Scott J Emrich, Andrew D Kern, Michael C Fontaine and Nora J Besansky | Summary: Abstract Local adaptation results in the formation of ecotypes–conspecific groups with heritable differences that increase fitness to distinct environments. The adaptive significance of ecotypes […]

Semantic-Guided Generative Image Augmentation Method with Diffusion Models for Image Classification

Posted by dbos Berkeley

Kavli Affiliate: Feng Wang | First 5 Authors: Bohan Li, Xiao Xu, Xinghao Wang, Yutai Hou, Yunlong Feng | Summary: Existing image augmentation methods consist of two categories: perturbation-based methods and generative methods. Perturbation-based methods apply pre-defined perturbations to augment an original image, but only locally vary the image, thus lacking image diversity. In contrast, […]

Construction of a 3D whole organism spatial atlas by joint modeling of multiple slices

Posted by klaurent UCSD / Salk

Kavli Affiliate: Angela Wu | Authors: Gefei Wang, Jia Zhao, Yan Yan, Yang Wang, Angela Ruohao Wu and Can Yang | Summary: Spatial transcriptomics (ST) technologies are revolutionizing the way that researchers explore the spatial architecture of tissues. Currently, ST data analysis is often restricted to 2D space within a single tissue slice, limiting our […]

Auditory memory of complex sounds in sparsely distributed, highly correlated neurons in the auditory cortex

Posted by klaurent Hopkins

Kavli Affiliate: Patrick Kanold | Authors: HiJee Kang and Patrick O Kanold | Summary: Listening in complex sound environments requires rapid segregation of different sound sources e.g., speakers from each other, speakers from other sounds, or different instruments in an orchestra, and also adjust auditory processing on the prevailing sound conditions. Thus, fast encoding of […]

The double-drift illusion biases the marmoset oculomotor system

Posted by klaurent UCSD / Salk

Kavli Affiliate: John Reynolds | Authors: Nicholas M Dotson, Zachary W Davis, Jared M Salisbury, Stephanie E Palmer, Patrick Cavanagh and John Reynolds | Summary: Abstract The double-drift illusion has two unique characteristics: the error between the perceived and physical position of the stimulus grows over time, and saccades to the moving target land much […]

Histone bivalency regulates the timing of cerebellar granule cell development

Posted by klaurent Rockefeller

Kavli Affiliate: Mary E. Hatten, C. David Allis | Authors: Kärt Mätlik, Eve-Ellen Govek, Matthew R. Paul, C. David Allis and Mary E. Hatten | Summary: Abstract Developing neurons undergo a progression of morphological and gene expression changes as they transition from neuronal progenitors to mature, multipolar neurons. Here we use RNA-seq and H3K4me3 and […]
