Advancing Precision Particle Background Estimation for Future X-ray Missions: Correlated Variability between AMS and Chandra/XMM-Newton

Posted by dbos May 10, 2024May 13, 2024MIT, This Week: Astrophysics

Kavli Affiliate: Eric D. Miller | First 5 Authors: Arnab Sarkar, Catherine E. Grant, Eric D. Miller, Mark Bautz, Benjamin Schneider | Summary: Galactic cosmic ray (GCR) particles have a significant impact on the particle-induced background of X-ray observatories, and their flux exhibits substantial temporal variability, potentially influencing background levels. In this study, we present […]

Measurement of cesium $8P_{J}{rightarrow}$ $6P_{J’}$ electric quadrupole transition probabilities using fluorescence spectroscopy

Posted by dbos May 10, 2024May 13, 2024Peking, This Week: Astrophysics

Kavli Affiliate: Jing Wang | First 5 Authors: Jing Wang, Yuki Miyamoto, Hideaki Hara, Minoru Tanaka, Motomichi Tashiro | Summary: Fluorescence spectra of the $8P_{J}{rightarrow}$ $6P_{J’}$ ($J$ and $J’$ = 3/2, 1/2) electric quadrupole transition of cesium atoms have been observed with a heated cesium vapor cell. We determined the ratio of the transition probabilities […]

Phylogeny of neocortical-hippocampal projections provides insight in the nature of human memory

Posted by dbos May 9, 2024May 13, 2024NTNU, This Week: Neuroscience

Kavli Affiliate: Menno Witter | Authors: Daniel Reznik, Piotr Majka, Marcello GP Rosa, Menno P Witter and Christian F Doeller; | Summary: Throughout mammalian evolution, the hippocampal region, unlike the neocortex, largely preserved its cytoarchitectural organization and its role in mnemonic functions. This contrast raises the possibility that the hippocampal region receives different types of […]

Structure of the Flotillin Complex in a Native Membrane Environment

Posted by dbos May 9, 2024May 13, 2024Rockefeller, This Week: Neuroscience

Kavli Affiliate: Roderick MacKinnon | Authors: Ziao Fu and Roderick MacKinnon; | Summary: In this study we used cryo-electron microscopy to determine the structures of the Flotillin protein complex, part of the Stomatin, Prohibitin, Flotillin, and HflK/C (SPFH) superfamily, from cell-derived vesicles without detergents. It forms a right-handed helical barrel consisting of 22 pairs of […]

Are human connectomes heritable?

Posted by dbos May 9, 2024May 13, 2024Hopkins, This Week: Neuroscience

Kavli Affiliate: Joshua Vogelstein | Authors: Jaewon Chung, Eric W Bridgeford, Michael Powell, Derek Pisner, Ting Xu and Joshua T Vogelstein; | Summary: A complete understanding of human behavior and disease depends upon our ability to parse genetic and environmental influences in the human brain. The heritability of a trait quantifies the degree of its […]

A mismatch between striatal cholinergic pauses and dopaminergic reward prediction errors

Posted by dbos May 9, 2024May 13, 2024This Week: Neuroscience, UCSF

Kavli Affiliate: Joshua Berke | Authors: Mariana Duhne, Ali Mohebi, Kyoungjun Kim, Lilian Pelattini and Joshua D. Berke; | Summary: Movement, motivation and reward-related learning depend strongly on striatal dopamine and acetylcholine. These neuromodulators each regulate the other, and disturbances to their coordinated signals contribute to human disorders ranging from Parkinson’s Disease to depression and […]
