Why Sell What You Can License?: Contracting Around Statutory Protection of Intellectual Property

Historically, the transfer of goods has been through sale, a model regulated by public legislation. Increasingly, however, the transfer of goods is occurring through licensing, a model regulated by private legislation. Privately-legislated licenses—for such chattels as musical an...

The Emergence of X-Ray Emission Lines during Relativistic Radio-jet Formation in the Changing-look Active Galactic Nucleus 1ES 1927+654

Abstract We present results from a comprehensive multiwavelength monitoring campaign of the changing-look active galactic nucleus 1ES 1927+654 during the onset and evolution of a relativistic radio jet ∼(2022 May–2025 August), using observations from XMM-Newton, Swift, Telescopio...

JWST Reveals Refractory-rich Water Ice in Interstellar Comet 3I/ATLAS: Evidence for a Continuum of Grain Properties across Protoplanetary Disks

Abstract We present JWST/NIRSpec PRISM observations of the interstellar comet 3I/ATLAS obtained on 2025 August 6 (Epoch 1), 2025 December 22 (Epoch 2), and 2026 April 1 (Epoch 3), spanning 8 months around perihelion at heliocentric distances of 3.3, 2.4, and 5.7 au, respectively....

You Shall Not Pass (Without Modeling): High-resolution Analysis of KMT-2019-BLG-0253 using MORIA

Abstract We present the Microlensing Object high-Resolution Imaging Analysis pipeline, or MORIA . This is an automated procedure to reduce high-resolution Hubble Space Telescope (HST) images of microlensing targets, build empirical point-spread function (PSF) models from the data...

Bargaining for Innovation

Reward drives innovation. For this reason, Congress has enacted a system of patents, trademarks, and copyrights to incentivize innovation. Such publicly ordered intellectual property regulation supports public and private interests—mandating disclosure of the innovation while leg...

Feasibility of Collaborative Assessment and Management of Suicidality–Brief Intervention in an Emergency Department With Youth Who Are Suicidal

BACKGROUND: Emergency departments (EDs) are key entry points for many youth experiencing suicidal thoughts and behaviors into mental health care. ED clinicians play a critical role in crisis intervention, prevention, and linking patients to ongoing care, yet many report uncertain...

Chiral discrimination of amino acids in meteorite and desert soil extracts via single-molecule nanogap conductance

Life on Earth uses L-amino acids and D-sugars, whereas abiotic processes produce equal abundances of both enantiomers. Detecting enantiomeric excess among molecules of biological interest has therefore been proposed as a potential biosignature for life beyond Earth. However, robu...

Modeling Storm‐Time Post‐Midnight Equatorial Plasma Bubbles With SAMI3‐WACCMX: Impacts of Neutral Winds, Thermospheric Composition, and Atmospheric Waves

Abstract This study investigates the roles of neutral winds, composition and atmospheric waves in storm‐time post‐midnight equatorial plasma bubble (EPB) development using the coupled SAMI3‐WACCMX model. Simulations reveal the formation of post‐midnight EPBs extending beyond 1,50...

Effect Modification of Rescue Stenting in ICAS-Related Middle Cerebral Artery Occlusion: The Role of Thrombectomy Failure, Stenosis Severity, and ASPECTS

Rescue stenting (RS) is increasingly used for intracranial artery stenosis-related large vessel occlusion (ICAS-LVO), but optimal patient selection remains uncertain. We investigated the baseline and procedural factors associated with receiving RS and whether they modified the as...

Association of Picket‐Fence With Auroral Continuum Emissions

Abstract We present observations of aurora‐like “picket‐fence” emissions occurring simultaneously with broad‐band auroral continuum emission structures. The continuum structures exhibit spectral properties similar to the Strong Thermal Emission Velocity Enhancement (STEVE), but a...

Pulsed Infrared Emission from Magnetar 4U 0142+61 Detected by JWST

Abstract We report on a JWST observation of the magnetar 4U 0142+61 on 2024 August 18 with the Near-Infrared Camera (NIRCam). NIRCam observed the magnetar for 33 minutes in timing mode, providing a time resolution of 2.5 s. In the F410M filter (pivot wavelength 4.08 μ m), we meas...

High-grade serous ovarian cancer is associated with increased TP53 mutation burden in uterine lavage

High grade serous ovarian cancer (HGSC) has low survival partly due to the lack of methods for detection, diagnosis, and risk prediction. TP53 mutations, which drive HGSC, are found in gynecological tissues as the result of somatic evolution, but it is unknown whether an excess o...
