Optical Control of Cell-Surface and Endomembrane-Exclusive β-Adrenergic Receptor Signaling

Posted by klaurent Rockefeller

Kavli Affiliate: Michael W. Young | Authors: Waruna Thotamune, Sithurandi Ubeysinghe, Kendra Kumar Shrestha, Mahmoud Elhusse Mostafa, Michael C Young and Ajith Karunarathne | Summary: Beta-adrenergic receptors (βARs) are G protein-coupled receptors (GPCRs) that mediate catecholamine-induced stress responses, such as heart rate increase and bronchodilation. In addition to signals from the cell surface, βARs also […]

A Case for a Binary Black Hole System Revealed via Quasi-Periodic Outflows

Posted by dbos MIT

Kavli Affiliate: Erin Kara | First 5 Authors: Dheeraj R. Pasham, Francesco Tombesi, Petra Sukova, Michal Zajacek, Suvendu Rakshit | Summary: Binaries containing a compact object orbiting a supermassive black hole are thought to be precursors of gravitational wave events, but their identification has been extremely challenging. Here, we report quasi-periodic variability in X-ray absorption […]

Alive but Barely Kicking: News from 3+ years of Swift and XMM-Newton X-ray Monitoring of Quasi-Periodic Eruptions from eRO-QPE1

Posted by klaurent MIT

Kavli Affiliate: Dheeraj R. Pasham | First 5 Authors: Dheeraj R. Pasham, Eric R. Coughlin, Michal Zajacek, Itai Linial, Petra Sukova | Summary: Quasi-periodic Eruptions (QPEs) represent a novel class of extragalactic X-ray transients that are known to repeat at roughly regular intervals of a few hours to days. Their underlying physical mechanism is a […]

Lense-Thirring Precession after a Supermassive Black Hole Disrupts a Star

Posted by klaurent MIT

Kavli Affiliate: Dheeraj R. Pasham | First 5 Authors: Dheeraj R. Pasham, Michal Zajacek, C. J. Nixon, Eric R. Coughlin, Marzena Sniegowska | Summary: An accretion disk formed around a supermassive black hole (SMBH) after it disrupts a star is expected to be initially misaligned with respect to the black hole’s equatorial plane. This misalignment […]

Pheromone representation in the ant antennal lobe changes with age

Posted by klaurent Rockefeller

Kavli Affiliate: Daniel Kronauer | Authors: Taylor Hart, Lindsey E. Lopes, Dominic D. Frank and Daniel J.C. Kronauer | Summary: While the neural basis of age-related decline has been extensively studied (1–3), less is known about changes in neural function during the pre-senescent stages of adulthood. Adult neural plasticity is likely a key factor in […]
