Torsion Balance Experiments Enable Direct Detection of Sub-eV Dark Matter

Posted by dbos Tokyo

Kavli Affiliate: Shigeki Matsumoto | First 5 Authors: Shigeki Matsumoto, Jie Sheng, Chuan-Yang Xing, Lin Zhu, | Summary: Light dark matter with sub-eV masses has a high number density in our galaxy, and its scattering cross section with macroscopic objects can be significantly enhanced by coherence effects. Repeated scattering with a target object can induce […]

Temporally-segregated dual functions for Gfi1 in the development of retinal direction-selectivity

Posted by dbos Hopkins

Kavli Affiliate: Alex Kolodkin | Authors: Karina Chaudhari, Luis E Guzman-Clavel and Alex L Kolodkin | Summary: There is great diversity in retinal ganglion cells subtypes in the mouse retina, but little is known about the molecular factors required to generate this subtype diversity. Here, we identify the transcription factor Gfi1 as a conserved driver […]
