Pumping the brakes on RNA velocity – understanding and interpreting RNA velocity estimates

Posted by klaurent June 25, 2022June 27, 2022Hopkins, This Week: Neuroscience

Kavli Affiliate: Loyal Goff | Authors: Shijie C. Zheng, Genevieve Stein-O’Brien, Leandros Boukas, Loyal A Goff and Kasper D Hansen | Summary: RNA velocity analysis of single cells promises to predict temporal dynamics from gene expression. Indeed, in many systems, it has been observed that RNA velocity produces a vector field that qualitatively reflects known […]

White matter and literacy: a dynamic system in flux

Posted by klaurent June 25, 2022June 27, 2022This Week: Neuroscience, UCSD / Salk

Kavli Affiliate: Terry Jernigan | Authors: SEthan Roy, Adam Richie-Halford, John Kruper, Manjari Narayan, David Bloom, Timoty T. Brown, Terry L. Jernigan, Bruce D. McCandliss, Ariel Rokem and Jason D. Yeatman | Summary: Past studies have linked differences in white matter tissue properties to reading skills. However, these studies have reported a range of, sometimes […]

Targeted cortical stimulation reveals principles of cortical contextual interactions

Posted by klaurent June 24, 2022June 27, 2022Columbia, This Week: Neuroscience

Kavli Affiliate: Kenneth Miller | Authors: Shen Wang, Agostina Palmigiano, Kenneth D Miller and Stephen David Van Hooser | Summary: Cross-orientation suppression is a classic form of contextual normalization in visual cortex, yet the degree to which cortical circuits participate in the normalization computation is unclear. We visualized orientation maps of individual ferrets, and provided […]

Angular analysis of $B^+ to ρ^+ρ^0$ decays reconstructed in 2019, 2020, and 2021 Belle II data

Posted by klaurent This Week: Astrophysics, Tokyo

Kavli Affiliate: T. Higuchi | First 5 Authors: Belle II Collaboration, F. Abudinén, I. Adachi, K. Adamczyk, L. Aggarwal | Summary: We report on a Belle II measurement of the branching fraction ($mathcal{B}$), longitudinal polarization fraction ($f_L$), and CP asymmetry ($mathcal{A}_{CP}$) of $B^+to rho^+rho^0$ decays. We reconstruct $B^+to rho^+(to pi^+pi^0(to gammagamma))rho^0(to pi^+pi^-)$ decays in a […]

X-ray Halos around Massive Galaxies: Data and Theory

Posted by klaurent June 23, 2022June 27, 2022MIT, This Week: Astrophysics

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Akos Bogdan, Mark Vogelsberger, , , | Summary: The presence of gaseous X-ray halos around massive galaxies is a basic prediction of all past and modern structure formation simulations. The importance of these X-ray halos is further emphasized by the fact that they retain signatures of the […]

A non-linear solution to the $S_8$ tension?

Posted by klaurent June 23, 2022June 27, 2022Cambridge, This Week: Astrophysics

Kavli Affiliate: George Efstathiou | First 5 Authors: Alexandra Amon, George Efstathiou, , , | Summary: Weak galaxy lensing surveys have consistently reported a lower amplitude for the matter fluctuation spectrum, as measured by the $S_8$ parameter, than expected in the $Lambda{rm CDM}$ cosmology favoured by $Planck$. However, the expansion history follows the predictions of […]

Bridging quantum many-body scar and quantum integrability in Ising chains with transverse and longitudinal fields

Posted by klaurent June 23, 2022June 27, 2022This Week: Theoretical Physics, UCAS

Kavli Affiliate: Cheng Peng | First 5 Authors: Cheng Peng, Xiaoling Cui, , , | Summary: Quantum many-body scar (QMBS) and quantum integrability(QI) have been recognized as two distinct mechanisms for the breakdown of eigenstate thermalization hypothesis(ETH) in an isolated system. In this work, we reveal a smooth route to connect these two ETH-breaking mechanisms […]

Chandra, HST/STIS, NICER, Swift, and TESS Detail the Flare Evolution of the Repeating Nuclear Transient ASASSN-14ko

Posted by klaurent June 22, 2022June 27, 2022MIT, This Week: Astrophysics

Kavli Affiliate: Michael M. Fausnaugh | First 5 Authors: Anna V. Payne, Katie Auchettl, Benjamin J. Shappee, Christopher S. Kochanek, Patricia T. Boyd | Summary: ASASSN-14ko is a nuclear transient at the center of the AGN ESO 253-G003 that undergoes periodic flares. Optical flares were first observed in 2014 by the All-Sky Automated Survey for […]
