mPFC Synaptosome Proteomics Reveals Novel Pathways and Muscarinic Receptor Changes in a Learned Helplessness Mouse Model

Posted by dbos January 30, 2026February 10, 2026Yale

Kavli Affiliate: Marina Picciotto | Authors: Zuhair I Abdulla, Rolando Garcia-Milian, Ernestine Giahyue, Sofia Fertuzinhos, Florine Collin, Weiwei Wang, TuKiet Lam, Angus Nairn and Marina R Picciotto | Summary: Stressful events are a leading factor in development of depression. The medial prefrontal cortex (mPFC) is strongly associated with depression etiology and exposure to uncontrollable stressors […]

Radial and Rotational Velocities of a Volume-Complete Sample of M Dwarfs with Masses 0.1-0.3 Msun within 15 parsecs

Posted by klaurent January 30, 2026February 10, 2026Harvard

Kavli Affiliate: David Charbonneau | Summary:We present the results from a five-year campaign to gather multi-epoch, high-resolution spectra of a volume-complete sample of 413 M dwarfs with masses 10-30% that of the Sun that lie within 15 parsecs. We report weighted mean systemic radial velocities (RV) and rotational broadening measurements ($v sin i$) for our […]

Dynamic Regulation of CD300b, and CD300f on Myeloid Cells in Oral Immunotherapy

Posted by dbos January 30, 2026February 10, 2026Columbia

Kavli Affiliate: Jean Fan | Authors: Caleb Hallinan, Hyun Joo Ji, Edmund Tsou, Steven L Salzberg and Jean Fan | Summary: The accuracy of spatial gene expression profiles generated by probe-based in situ spatially-resolved transcriptomic technologies depends on the specificity with which probes bind to their intended target gene. Off-target binding, defined as a probe […]

MATRIX: A Multimodal Benchmark and Post-Training Framework for Materials Science

Posted by klaurent January 30, 2026Berkeley

Kavli Affiliate: Gerbrand Ceder| Summary:Scientific reasoning in materials science requires integrating multimodal experimental evidence with underlying physical theory. Existing benchmarks make it difficult to assess whether incorporating visual experimental data during post-training improves mechanism-grounded explanation reasoning beyond text-only supervision. We introduce MATRIX, a multimodal benchmark for materials science reasoning that evaluates foundational theory, research-level reasoning, […]

3D Printed Alumina as a Millimeter-Wave Optical Element

Posted by klaurent January 30, 2026February 10, 2026Tokyo

Kavli Affiliate: Tomotake Matsumura | Summary:We present millimeter and sub-millimeter room temperature transmission and loss measurements of 3D printed alumina disc and of a disc with one-sided 3D printed sub-wavelength structures anti-reflection coatings (SWS-ARC). For four bands spanning 158 – 700~GHz we find an index of refraction consistent with $n= 3.107 pm 0.007$. The loss […]

Supernova Rates and Luminosity Functions from ASAS-SN III: Over a Decade of Type Ia SNe and Their Subtypes

Posted by klaurent January 30, 2026February 10, 2026Peking

Kavli Affiliate: Subo Dong | Summary:We present volumetric rates and luminosity functions (LFs) of Type Ia supernovae (SNe Ia) from the All-Sky Automated Survey for Supernovae (ASAS-SN), covering the 11-year period from 2014 to 2024. By combining the 2014–2017 $V$-band sample with the 2018–2024 $g$-band sample, we construct a large statistical dataset of $1776$ SNe […]

Weight-four parity checks with silicon spin qubits

Posted by klaurent January 30, 2026February 10, 2026Delft

Kavli Affiliate: Lieven Vandersypen | Summary:Recent advances in coherent spin shuttling have made sparse semiconductor spin qubit arrays an appealing solid-state platform to realize quantum processors. The dynamic and long-range connectivity enabled by shuttling is also essential for many quantum error-correction (QEC) schemes. Here, we demonstrate a silicon spin-qubit device that comprises a shuttling bus […]

The Effect of Tidal Heating and Volatile Budgets on the Outgassed Atmosphere of 55 Cancri e

Posted by klaurent January 30, 2026February 10, 2026Stanford

Kavli Affiliate: Laura Schaefer | Summary:55 Cancri e is a $sim$8 Gyr rocky world (1.95 $R_oplus$, 8.8 $M_oplus$) orbiting a K-type star. JWST observations suggest a carbon-dominated atmosphere (CO$_2$/CO) over a global magma ocean ($>$3000 K). We suggest that any CO$_2$-dominated atmosphere, with trace H$_2$O/O$_2$, likely arises from outgassing of its initial volatile reservoir. As […]
