Unusual Hard X-ray Flares Caught in NICER Monitoring of the Binary Supermassive Black Hole Candidate AT2019cuk/Tick Tock/SDSS J1430+2303

Posted by klaurent February 24, 2023MIT

Kavli Affiliate: Ronald A. Remillard | First 5 Authors: Megan Masterson, Erin Kara, Dheeraj R. Pasham, Daniel J. D’Orazio, Dominic J. Walton | Summary: The nuclear transient AT2019cuk/Tick Tock/SDSS J1430+2303 has been suggested to harbor a supermassive black hole (SMBH) binary near coalescence. We report results from high-cadence NICER X-ray monitoring with multiple visits per […]

Determining Molecular Complexity using Assembly Theory and Spectroscopy

Posted by klaurent February 24, 2023Stanford

Kavli Affiliate: Stuart Marshall | Summary:Determining the complexity of molecules has important applications from molecular design to understanding the history of the process that led to the formation of the molecule. Currently, it is not possible to experimentally determine, without full structure elucidation, how complex a molecule is. Assembly Theory has been developed to quantify […]

A new twist on PIFE: photoisomerisation-related fluorescence enhancement

Posted by klaurent February 24, 2023Oxford

Kavli Affiliate: Achillefs Kapanidis | Summary:PIFE was first used as an acronym for protein-induced fluorescence enhancement, which refers to the increase in fluorescence observed upon the interaction of a fluorophore, such as a cyanine, with a protein. This fluorescence enhancement is due to changes in the rate of cis/trans photoisomerisation. It is clear now that […]

Neuronal Transcriptome Disruption, Tau Accumulation and Synapse Loss in Alzheimer’s Knock-in Mice Require Cellular Prion Protein

Posted by klaurent February 23, 2023March 7, 2023Yale

Kavli Affiliate: Stephen Strittmatter | Authors: Austin Stoner, Li Fu, LaShae Nicholson, Chao Zheng, Takuya Toyonaga, Joshua Spurrier, Will Laird, Zhengxin Cai and Stephen M. Strittmatter | Summary: Background Cellular prion protein (PrPC) is a high-affinity cell-surface receptor for Amyloid-β oligomers (Aßo). In certain overexpression models of Alzheimer’s Disease (AD), pharmacology and genetics demonstrate its […]

Sidelobe Modeling and Mitigation for a Three Mirror Anastigmat Cosmic Microwave Background Telescope

Posted by February 21, 2023Chicago

Kavli Affiliate: John Carlstrom | First 5 Authors: Ian Gullett, Bradford Benson, Robert Besuner, Richard Bihary, John Carlstrom | Summary: Telescopes measuring cosmic microwave background (CMB) polarization on large angular scales require exquisite control of systematic errors to ensure the fidelity of the cosmological results. In particular, far-sidelobe contamination from wide angle scattering is a […]
