Genomic expression responses in sensu stricto Saccharomyces yeast to DNA damage induced by methyl methanesulfonate

Posted by klaurent UCSD / Salk

Kavli Affiliate: V. S. Ramachandran | Authors: Vignesh Ramachandran, Gregory Hatlestad and Travis White | Summary: Background: One way single-celled eukaryotes respond to DNA damage stress is by modifying their gene expression, facilitating genomic repair. Gene expression responses to DNA damage induced by methyl methanesulfonate (MMS) have been studied in the model organism Saccharomyces cerevisiae. […]

Distinct roles of dentate gyrus and medial entorhinal cortex inputs for phase precession and temporal correlations in hippocampal CA3 place cells

Posted by klaurent UCSD / Salk

Kavli Affiliate: Solomon Snyder | Authors: Robin Roychaudhuri, Hasti Atashi and Solomon Snyder | Summary: The hippocampal CA3 subregion is a densely connected recurrent circuit that supports memory consolidation and retrieval by generating and storing sequential neuronal activity patterns that reflect recent experience. The encoding of precise temporal firing patterns in CA3 ensembles during awake-behavior […]

Serine Racemase mediates Subventricular Zone Neurogenesis via Fatty acid Metabolism.

Posted by klaurent Hopkins

Kavli Affiliate: Solomon Snyder | Authors: Robin Roychaudhuri, Hasti Atashi and Solomon Snyder | Summary: The adult subventricular zone is one of the two neurogenic niches that continuously produce newborn neurons. Here we show that serine racemase (SR), an enzyme that catalyzes the racemization of L-serine to D-serine and vice versa, affects neurogenesis in the […]

Age-related learning and working memory impairment in the common marmoset

Posted by klaurent UCSD / Salk

Kavli Affiliate: John Reynolds | Authors: Courtney Glavis-Bloom, Casey R Vanderlip and John H Reynolds | Summary: Aging is the greatest risk factor for the development of neurodegenerative diseases, yet we still do not understand how the aging process leads to pathological vulnerability. The research community has relied heavily on mouse models, but the considerable […]

Reconstructing the cascade of language processing in the brain using the internal computations of a transformer-based language model

Posted by klaurent Columbia

Kavli Affiliate: Robert Hawkins | Authors: Sreejan Kumar, Theodore R. Sumers, Takateru Yamakoshi, Ariel Goldstein, Uri Hasson, Kenneth A. Norman, Thomas L. Griffiths, Robert D. Hawkins and Samuel A. Nastase | Summary: Piecing together the meaning of a narrative requires understanding not only the individual words but also the intricate relationships between them. How does […]

Shock Breakout in 3-Dimensional Red Supergiant Envelopes

Posted by klaurent UCSB

Kavli Affiliate: Lars Bildsten | First 5 Authors: Jared A. Goldberg, Yan-fei Jiang, Lars Bildsten, , | Summary: Using Athena++, we perform 3D Radiation-Hydrodynamic calculations of the radiative breakout of the shock wave in the outer envelope of a red supergiant (RSG) which has suffered core collapse and will become a Type IIP supernova. The […]

TESS Shines Light on the Origin of the Ambiguous Nuclear Transient ASASSN-18el

Posted by dbos MIT

Kavli Affiliate: Michael Fausnaugh | First 5 Authors: Jason T. Hinkle, Christopher S. Kochanek, Benjamin J. Shappee, Patrick J. Vallely, Katie Auchettl | Summary: We analyze high-cadence data from the Transiting Exoplanet Survey Satellite (TESS) of the ambiguous nuclear transient (ANT) ASASSN-18el. The optical changing-look phenomenon in ASASSN-18el has been argued to be due to […]

Cosmological Magnetic Fields from Primordial Kerr-Newman Black Holes

Posted by klaurent Chicago

Kavli Affiliate: Gordan Krnjaic | First 5 Authors: Dan Hooper, Aurora Ireland, Gordan Krnjaic, , | Summary: The origin of our universe’s cosmological magnetic fields remains a mystery. In this study, we consider whether these magnetic fields could have been generated in the early universe by a population of charged, spinning primordial black holes. To […]

Nonadiabatic transition paths from quantum jump trajectories

Posted by klaurent Berkeley

Kavli Affiliate: David T. Limmer | First 5 Authors: Michelle C. Anderson, Addison J. Schile, David T. Limmer, , | Summary: We present a means of studying rare reactive pathways in open quantum systems using Transition Path Theory and ensembles of quantum jump trajectories. This approach allows for elucidation of reactive paths for dissipative, nonadiabatic […]
