From starlight to dark matter: a stochastic interpolation approach to map dark matter from stellar density

Posted by klaurent MIT

Kavli Affiliate: Lina Necib | Summary:The dark matter halo profile in galaxies holds key information about the nature of dark matter and galaxy formation. Constraining the dark matter profile of galaxies beyond the Milky Way traditionally requires expensive spectroscopic observations for kinematic information. In this paper, we explore a conditional generative model framework to map […]

Depolarization block in substantia nigra pars reticulata neurons drives dystonia in a mouse model

Posted by dbos UCSF

Kavli Affiliate: Alexandra Nelson | Authors: Olivia K Barnhill, Kasandra M Romo and Alexandra B Nelson | Summary: Dystonia is a common movement disorder characterized by involuntary co-contraction of antagonist muscles, resulting in abnormal postures. The brain often appears grossly normal, suggesting dysfunctional neural activity as a cause. The basal ganglia are implicated in dystonia, […]

Kavli Affiliate: Jin Kang | Authors: Jisu Hong, Jinwoong Lim, Minho Park, Jimin Song, Byung Joon Lee, Miyoung Park, Min-Kyoo Shin, Hyungseok Seo, Hyoung Jin Kang, Byung-Soo Kim and Chang-Han Lee | Summary: Chimeric antigen receptor (CAR)-T cells and CAR-macrophages (or CAR-monocytes) offer complementary antitumor functions. CAR-T cells exert potent cytotoxicity against cancer cells, whereas […]

The Simons Observatory: Commissioning of the Mid-Frequency Small Aperture Telescopes

Posted by klaurent Stanford

Kavli Affiliate: Shawn Henderson | Summary:The Simons Observatory (SO) is a cosmic microwave background (CMB) survey experiment observing from an altitude of 5,200 m in the Atacama Desert in Chile. The SO Small Aperture Telescopes (SATs) will cover six spectral bands between 30 and 280 GHz primarily to search for evidence of primordial gravitational waves […]

SN2025aico: An Interesting Case Of $^56$Ni Mixing, Ejecta Asymmetries, and Dust Formation in a Type IIb Supernova

Posted by klaurent Tokyo

Kavli Affiliate: Shunsaku Horiuchi | Summary:Stripped-envelope supernovae provide a window into how massive stars lose their layers, mix radioactive material, produce dust, and explode asymmetrically. We present optical, near-infrared (NIR), and mid-infrared (MIR) observations of SN~2025aico, a Type~IIb supernova in LEDA~35384. Our spectroscopic sequence, spanning $+1$ to $+167$ d after explosion, follows its evolution from […]

Lasting aversive consequences of a single dose of 4-hydroxytamoxifen

Posted by dbos Columbia

Kavli Affiliate: Daniel Salzman | Authors: Evan J. Kyzar, Ruby Setara, Maya Eisengart, Sophia Virkar, Lydia Rogerson, Alejandro Ramirez and C. Daniel Salzman | Summary: 4-hydroxytamoxifen (4-OHT) is commonly used to facilitate activity-dependent recombination in neurons. Here we show that one dose of 4-OHT devalues alcohol, contexts, and tastants, indicating that experimental designs using 4-OHT […]

Rocking Without a Tune: Ex vivo and in vivo Responses to Sound in the Basilar Papilla of the Tokay Gecko

Posted by dbos Rockefeller

Kavli Affiliate: A. James Hudspeth | Authors: Brian L. Frost, Yuriria Vázquez, Kazuhiro Horii, Brian A. Fabella and A. J. Hudspeth | Summary: Like mammals, some reptiles possess sensitive and frequency-selective hearing at mid- to high-kilohertz frequencies. Both groups employ a place-frequency map within the inner ear to encode sound stimuli, but the mechanisms by […]

Manipulating attentional priority creates a trade-off between memory and sensory representations in human visual cortex

Posted by dbos UCSD / Salk

Kavli Affiliate: John Serences | Authors: Rosanne L Rademaker and John Serences | Summary: People often remember visual information over brief delays while actively engaging with ongoing inputs from the surrounding visual environment. Depending on the situation, one might prioritize mnemonic contents (i.e., remembering details of a past event), or preferentially attend sensory inputs (i.e., […]

Three-Dimensional Imaging of High-Density Dislocation Networks and Their Interactions using Multislice Electron Ptychography

Posted by klaurent Cornell

Kavli Affiliate: David Muller | Summary:Development of novel devices often involve combining functional materials and substrates, each chosen for particular physical properties such as low-loss or thermal conductivity. This, however, can introduce a large lattice mismatch and high density of structural defects that may limit device performance and reliability by trapping charge or creating leakage […]

A Simple Dark Matter Model to Explain the LZ Event and Galactic Center Excess

Posted by klaurent Chicago

Kavli Affiliate: Gordan Krnjaic | Summary:We propose that the dark matter (DM) is a pseudo-Dirac fermion with a mass of approximately $20-100$ GeV that couples inelastically to the Standard Model through a hadrophilic spin-1 mediator, $V$, the gauge boson of spontaneously broken baryon number. The two DM eigenstates, $χ_1$ and $χ_2$, acquire approximately equal abundances […]
