Kavli Affiliate: Max Tegmark | First 5 Authors: David “davidad” Dalrymple, Joar Skalse, Yoshua Bengio, Stuart Russell, Max Tegmark | Summary: Ensuring that AI systems reliably and robustly avoid harmful or dangerous behaviours is a crucial challenge, especially for AI systems with a high degree of autonomy and general intelligence, or systems used in safety-critical […]
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 […]

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 […]
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 […]
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 […]
Kavli Affiliate: Kay Tye | Authors: Alexander Lin, Cyril Akafia, Olga Dal Monte, Siqi Fan, Nicholas Fagan, Philip Putnam, Kay M. Tye, Steve Chang, Demba Ba and AZA Stephen Allsop; | Summary: In neuroscience, understanding how single-neuron firing contributes to distributed neural ensembles is crucial. Traditional methods of analysis have been limited to descriptions of […]
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 […]
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 […]
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 […]
