Distinct spatial and non-spatial response properties of excitatory narrow-spike and burst-firing neurons in the marmoset auditory cortex

Posted by dbos February 11, 2026February 23, 2026Hopkins

Kavli Affiliate: Xiaoqin Wan | Authors: Chenggang Chen, Evan D Remington and Xiaoqin Wang | Summary: Cell types are the basic units of the cerebral cortex. Broad and narrow spike waveforms (BW and NW) are the primary criteria for classifying putative excitatory and inhibitory cortical neurons, particularly in non-human primates where genetic accessibility is limited.

Measurement prospects for the pair-instability mass cutoff with gravitational waves

Posted by klaurent February 11, 2026MIT

Kavli Affiliate: Salvatore Vitale | Summary:Pair-instability supernovae leave behind no compact remnants, resulting in a predicted gap in the distribution of stellar black-hole masses. Gravitational waves from binary black-hole mergers probe the relevant mass range and analyses of the LIGO-Virgo-KAGRA catalog (GWTC-4) indicate a possible mass cutoff at $40$-$50,M_odot$. However, the robustness of this result […]

Gas-depleted planet formation occurred in the four-planet system around the red dwarf LHS 1903

Posted by klaurent February 11, 2026MIT

Kavli Affiliate: Sara Seager | Summary:Small exoplanet radii show two populations, referred to as super-Earths and sub-Neptunes, separated by a gap known as the radius valley. This may be produced by the removal of atmospheres due to stellar or internal heating, or lack of an initial envelope. We us transit photometry and radial velocity measurements […]

An Enhanced Formation Channel for Galactic Dual-Line Gravitational-Wave Sources: von Zeipel-Lidov-Kozai Effect in Triples Involving Sgr A*

Posted by klaurent February 11, 2026Peking

Kavli Affiliate: Lijing Shao | Summary:The dense Galactic Center environment is expected to host compact binary inspirals detectable by future space-borne gravitational wave (GW) observatories (e.g., LISA, TianQin, Taiji) in the millihertz band. Aided by information from these facilities, next-generation ground-based GW detectors (e.g., Cosmic Explorer, Einstein Telescope) can potentially capture gravitational radiation in the […]

Latent-centric Isotropic Resolution Enhancement for Expansion Microscopy Imaging via Neural Compression and Self-supervised Learning

Posted by dbos February 10, 2026February 23, 2026UCSD / Salk

Kavli Affiliate: Ann-Shyn Chiang | Authors: Pin-Hsun Lian, Tzu-Yi Chuang, Ya-Ding Liu, Li-An Chu, Sheng-Cheng Chang, Yu-Chen Kuo, Wei-Kun Chang, Ann-Shyn Chiang and Gary Chang | Summary: Expansion microscopy (ExM) enables nanoscale imaging for disease characterization. However, whole-organ analyses remain limited by several challenges. Current super-resolution methods either require high-resolution ground-truth data or assume spatially […]

Field-driven Ion Pairing Dynamics in Concentrated Electrolytes

Posted by klaurent February 10, 2026February 23, 2026Berkeley

Kavli Affiliate: David T. Limmer | Summary:We investigate ion pairing dynamics in electrolytes driven far from equilibrium using molecular simulations and nonequilibrium rate theory. Focusing on 0.5 M $mathrmLiPF_6$ in water and acetonitrile under uniform electric fields, we compute transition path theory observables including reactive fluxes and mean first-passage times of ion pairing. Moreover, we […]

Keck Observations in the INfrared of Taurus and $ρ$ Oph Exoplanets And Ultracool dwarfs (KOINTREAU) II: Two Young Bound Companions to Ophiuchus Stars

Posted by klaurent February 10, 2026Caltech

Kavli Affiliate: Dimitri Mawet| Summary:We present the second set of discoveries from Keck Observations in the INfrared of Taurus and $ρ$ Oph Exoplanets And Ultracool dwarfs (KOINTREAU), an adaptive optics survey of young stars in the Taurus and $ρ$ Oph star-forming regions using Keck/NIRC2 in conjunction with the Keck infrared pyramid wavefront sensor. We have […]

Relativistic Effects in LaBi$_2$ Thin Films

Posted by klaurent February 10, 2026February 23, 2026Caltech

Kavli Affiliate: Joseph Falson | Summary:Chemical substitution in crystalline quantum materials is a powerful way to explore the consequences of strong spin-orbit coupling on their structural and electronic properties. In this work, we present an investigation of thin films of the La$textitPn_2$ ($textitPn$~=~Sb, Bi) class of layered square-net intermetallics. We report the growth of LaBi$_2$ […]
