Unselfish meiotic drive maintains heterozygosity in a parthenogenetic ant

Posted by klaurent Rockefeller

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

Posted by klaurent Stanford

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 with Illustris TNG300 hydrodynamic simulation data. We predict stellar masses from subhalo properties to test two types of machine learning (ML) […]

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

Posted by klaurent MIT

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

Posted by klaurent MIT

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 […]

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

Posted by klaurent UCSF

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. […]

Flux-tunable Kitaev chain in a quantum dot array

Posted by klaurent Delft

Kavli Affiliate: Michael Wimmer | First 5 Authors: Juan Daniel Torres Luna, A. Mert Bozkurt, Michael Wimmer, Chun-Xiao Liu, | Summary: Connecting quantum dots through Andreev bound states in a semiconductor-superconductor hybrid provides a platform to create a Kitaev chain. Interestingly, in a double quantum dot, a pair of poor man’s Majorana zero modes can […]

The PFS view of TOI-677 b: A spin-orbit aligned warm Jupiter in a dynamically hot system

Posted by klaurent MIT

Kavli Affiliate: Avi Shporer | First 5 Authors: Qingru Hu, Malena Rice, Xian-Yu Wang, Songhu Wang, Avi Shporer | Summary: TOI-677 b is part of an emerging class of “tidally-detached” gas giants ($a/R_star gtrsim 11$) that exhibit large orbital eccentricities and yet low stellar obliquities. Such sources pose a challenge for models of giant planet […]

The TESS-Keck Survey. XVIII. A sub-Neptune and spurious long-period signal in the TOI-1751 system

Posted by klaurent MIT

Kavli Affiliate: Alan M. Levine | First 5 Authors: Anmol Desai, Emma V. Turtelboom, Caleb K. Harada, Courtney D. Dressing, David R. Rice | Summary: We present and confirm TOI-1751 b, a transiting sub-Neptune orbiting a slightly evolved, solar-type, metal-poor star ($T_{eff} = 5996 pm 110$ K, $log(g) = 4.2 pm 0.1$, V = 9.3 […]

A Strontium-rich Ultra Metal-poor Star in the Atari Disk Component

Posted by klaurent MIT

Kavli Affiliate: Anna Frebel | First 5 Authors: Mohammad K. Mardini, Anna Frebel, Anirudh Chiti, , | Summary: We report on the discovery of the first ultra metal-poor (UMP) star 2MASS~J20500194$-$6613298 (J2050$-$6613; mbox{[Fe/H] = $-4.05$}) selected from the Gaia BP/RP spectral catalog that belongs to the ancient Atari disk component. We obtained a high-resolution spectrum […]
