Canonical decision computations underlie behavioral and neural signatures of cooperation in primates

Posted by dbos March 11, 2026March 23, 2026Yale

Kavli Affiliate: Anirvan Nandy | Authors: Weikang Shi, Olivia C. Meisner, Monika P. Jadi, Steve W. C. Chang and Anirvan S. Nandy | Summary: Successful cooperation requires dynamic integration of social cues. However, the neural mechanisms supporting this complex process remain unknown. Here, we reveal that the primate dorsomedial prefrontal cortex (dmPFC) implements a gaze-dependent […]

Auroral Acceleration Generates Electron Beams in Jupiter’s Middle Magnetosphere

Posted by klaurent March 11, 2026March 23, 2026MIT

Kavli Affiliate: George Clark | Summary:Observations made by the Juno spacecraft above Jupiter’s polar regions have revealed that electrons accelerated toward Jupiter, which contribute to auroral emissions, are frequently accompanied by electrons accelerated away from Jupiter. These electrons should be observable as narrow electron beams in the middle magnetosphere, in accordance with the principles of […]

Novae breves from magnetar giant flares: Potential probes of neutron star crusts

Posted by klaurent March 11, 2026March 23, 2026Peking

Kavli Affiliate: Lijing Shao | Summary:Matter ejected from the magnetar crust during giant flares (GFs) may undergo $r$-process nucleosynthesis, producing short-lived optical transients termed "novae breves". Although intrinsically much fainter than kilonovae from compact binary mergers, novae breves may occur within or near the Galaxy, making them promising observational targets. We aim to investigate how […]

Active pursuit gates egocentric coding in Retrosplenial Cortex

Posted by dbos March 10, 2026March 23, 2026NTNU

Kavli Affiliate: Jonathan Whitlock | Authors: Pearl Saldanha, Martin Bjerke, Benjamin Adric Dunn and Jonathan Robert Whitlock | Summary: Spatial navigation is commonly studied in static environments, but adaptive behavior frequently hinges on tracking moving goals in real time. Active pursuit exemplifies this challenge, since it is an inherently egocentric spatial behavior requiring continual localization […]

Learning to Decode Quantum LDPC Codes Via Belief Propagation

Posted by klaurent March 10, 2026March 23, 2026Chicago

Kavli Affiliate: Salman Habib | Summary:Belief-propagation (BP) decoding for quantum low-density parity-check (QLDPC) codes is appealing due to its low complexity, yet it often exhibits convergence issues due to quantum degeneracy and short cycles that exist in the Tanner graph. To overcome this challenge, this paper proposes a reinforcement-learning (RL) approach that learns (offline) how […]

The React & Rebound Model: Capturing Emotion Regulation Dynamics from Passive Wearable Data

Posted by dbos March 10, 2026March 23, 2026UCSF

Kavli Affiliate: Adam Gazzaley | Authors: Andrew C Heusser, Tony J Simon, Esther Elliot, Christopher James, Adam Gazzaley and Nicole Gibson | Summary: Background Emotion regulation—the ability to respond to and restore equilibrium after emotional perturbations—is central to mental health. Yet objective measurement remains limited to lab-based studies with group-level results, while consumer wearables focus […]

A Kiloparsec-Scale Stellar Cavity in the Center of Abell402-BCG May be Caused by Dynamic Interactions with an Ultramassive Black Hole

Posted by klaurent March 10, 2026March 23, 2026MIT

Kavli Affiliate: Scott A. Hughes | Summary:We present new observations from JWST NIRCam that reveal a striking kpc-wide cavity in the stellar distribution of the central galaxy in the cluster Abell402. Supporting data from HST allow us to rule out extinction due to dust as an explanation and, instead, suggest that this is a localized […]

Probing Physics Beyond the Standard Model through Combined Analyses of Next-Generation Type Ia Supernova, CMB, and BAO Surveys

Posted by klaurent March 10, 2026Chicago

Kavli Affiliate: Richard Kessler | Summary:Observations of Type Ia supernovae (sne), which probe the late Universe, together with baryon acoustic oscillations (BAO) and the cosmic microwave background (CMB), which probe the intermediate and early epochs, provide complementary constraints on the expansion history of the Universe. In this work, we forecast constraints on dark energy and […]

Posted by klaurent March 10, 2026March 23, 2026Chicago

Kavli Affiliate: Richard Kessler | Summary:Observations of Type Ia supernovae (SNIa), baryon acoustic oscillations (BAO), and the cosmic microwave background (CMB), which probe the late-, intermediate-, and early-universe epochs, respectively, provide complementary constraints on the expansion history of the Universe. In this work, we forecast constraints on dark energy and other extensions to the standard […]

Far-infrared Polarization Properties of Nearby Star-forming Regions: A New Compendium of SOFIA/HAWC+ Observations

Posted by klaurent March 10, 2026Stanford

Kavli Affiliate: Susan Clark | Summary:We present a comprehensive polarimetric study of 26 nearby molecular clouds in four far-infrared bands (53 $μ$m~to 214~$μ$m) using 52 archival SOFIA/HAWC+ datasets, over half of which are unpublished. Far-infrared dust polarization observations probe the plane-of-sky magnetic field. To investigate scale-dependent trends, we group the molecular clouds by distance and […]
