Unselfish meiotic drive maintains heterozygosity in a parthenogenetic ant

Kavli Affiliate: Daniel Kronauer | Authors: Kip D Lacy, Taylor Hart and Daniel J.C. Kronauer | Summary: According to Mendel’s second law, chromosomes segregate randomly in meiosis. Non-random segregation is primarily known for cases of selfish meiotic drive in females, in which particular alleles bias their own transmission into the oocyte1,2. Here, we report a […]

How the Galaxy-Halo Connection Depends on Large-Scale Environment

Kavli Affiliate: Risa H. Wechsler | First 5 Authors: John F. Wu, Christian Kragh Jespersen, Risa H. Wechsler, , | Summary: We investigate the connection between galaxies, dark matter halos, and their large-scale environments at $z=0$ with Illustris TNG300 hydrodynamic simulation data. We predict stellar masses from subhalo properties to test two types of machine […]

Ephemeris Matching Reveals False Positive Validated and Candidate Planets from the K2 Mission

Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Drake A. Lehmann, Andrew Vanderburg, , , | Summary: Data from the Kepler space telescope have led to the discovery of thousands of planet candidates. Most of these candidates are likely to be real exoplanets, but a significant number of false positives still contaminate the sample, especially […]

CHIME/FRB Outriggers: KKO Station System and Commissioning Results

Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: Adam E. Lanman, Shion Andrew, Mattias Lazda, Vishwangi Shah, Mandana Amiri | Summary: Localizing fast radio bursts (FRBs) to their host galaxies is an essential step to better understanding their origins and using them as cosmic probes. The CHIME/FRB Outrigger program aims to add VLBI-localization capabilities […]

The TESS-Keck Survey XXI: 13 New Planets and Homogeneous Properties for 21 Subgiant Systems

Kavli Affiliate: Roland Vanderspek | First 5 Authors: Ashley Chontos, Daniel Huber, Samuel K. Grunblatt, Nicholas Saunders, Joshua N. Winn | Summary: We present a dedicated transit and radial velocity survey of planets orbiting subgiant stars observed by the TESS Mission. Using $sim$$16$ nights on Keck/HIRES, we confirm and characterize $12$ new transiting planets — […]

Intercalated amygdala dysfunction drives extinction deficits in the Sapap3 mouse model of obsessive-compulsive disorder

Kavli Affiliate: Anatol Kreitzer | Authors: Robyn St. Laurent, Kelly M Kusche, Anatol C Kreitzer and Robert C Malenka | Summary: Background The avoidance of aversive stimuli due to negative reinforcement learning is critical for survival in real-world environments, which demand dynamic responding to both positive and negative stimuli that often conflict with each other. […]
