Proteomics approaches to ecoimmunology: new insights into wildlife immunity and disease

June 24, 2025
Author(s)
Amanda Vicente-Santos1, Natalia Herrera, Gabor Czirjak, Benjamin Neely, Daniel Becker
Understanding wildlife immune responses is crucial for assessing disease risks, environmental stress effects, and conservation challenges. Traditional ecoimmunology approaches rely on targeted assays, which, while informative, often provide a fragmented

Blackbody radiation Zeeman shift in Rydberg atoms

June 23, 2025
Author(s)
Kyle Beloy, Benjamin Hunt, Roger Brown, Tobias Bothwell, Youssef Hassan, Jacob Siegel, Tanner Grogan, Andrew Ludlow
We consider the Zeeman shift in Rydberg atoms induced by room-temperature blackbody radiation (BBR). BBR shifts to the Rydberg levels are dominated by the familiar BBR Stark shift. However, the BBR Stark shift and the BBR Zeeman shift exhibit different

First direct search for light dark matter interactions in a transition-edge sensor

June 23, 2025
Author(s)
Christina Schwemmbauer, Adriana Lita, Yonit Hochberg, Axel Lindner, Friederike Januschek, Manuel Meyer, Benjamin Lehmann
We propose the use of transition-edge sensor (TES) single-photon detectors as a simultaneous target and sensor for direct dark matter searches, and report results from the first search of this kind. We perform a 489 h science run with a TES device

Quasi-Elastic Neutron Scattering on Bimodal Dynamics in Molecular Solutions of Cellulose

June 23, 2025
Author(s)
Tao Xiong, Madhu Sudan Tyagi, Wei Zhou, Hongyu Guo, Robert Briber, Howard Wang
Local dynamics in molecular solutions of cellulose have been studied using quasi-elastic neutron scattering on ternary mixtures of microcrystalline cellulose, ionic liquid 1-ethyl-3-methyl-imidazolium acetate and co-solvent dimethylformamide. Two distinct

X-ray scintillating lanthanide-based coordination polymers

June 23, 2025
Author(s)
Elizabeth Decoteau, Claire Belatti, Huong Giang Nguyen, Luiz Jacobsohn, Robert Surbella, III, Christopher Cahill
Reported are the syntheses and characterization of 25 lanthanide-containing coordination polymers exhibiting four structure types: type I': [Ln(TFTP)1.5(bpy)] (Ln = La3+-Nd3+), type I: [Ln(TFTP)1.5(bpy)(H2O)] (Ln = Sm3+-Lu3+), type II': [Pr(TFTP)1.5(phen)]

Characterizing rapid changes in the prevalence and concentration of key compounds in Philadelphia's fentanyl supply, March-November 2024

June 22, 2025
Author(s)
Karli Hochstatter, Talia Nadel, Edward Sisco, Sarah Laurel, Tori McDowell, Elise Pyfrom, Meghan Appley, Fernando Montero
Objective: The objective of this observational epidemiological study is to examine recent shifts in the street opioid supply of the largest U.S. open-air drug market, including changes in prevalence and concentration of key compounds. Methods: From March

Enabling data-driven design of block copolymer self-assembly

June 21, 2025
Author(s)
Chiara Magosso, Irdi Murataj, Michele Perego, Gabriele Seguini, Debra Audus, Gianluca Milano, Federico Ferrarese Lupi
Abstract Here we present a database composed of scanning electron microscope images of self-assembled block copolymers. The fabrication process parameters, structural properties and microscope information are all contained in the image metadata, making a

Analysis of Propagation of Regular, Extended, and Large BGP Communities

June 20, 2025
Author(s)
Lilia Hannachi, Kotikalapudi Sriram, Douglas Montgomery
This study focuses on the analysis of propagation of Regular, Extended, and Large Communities in the Border Gateway Protocol (BGP). Once added, these communities are often intended to be transitive by default, meaning that they should be propagated from

Experimental Evaluation of AI-Driven Protein Design Risks Using Safe Biological Proxies

June 20, 2025
Author(s)
Svetlana Ikonomova, Bruce Wittmann, Fernanda Piorino Macruz de Oliveira, David Ross, Samuel Schaffter, Olga Vasilyeva, Elizabeth Strychalski, Eric Horvitz, James Diggans, Sheng Lin-Gibson, Geoffrey Taghon
Advances in machine learning are providing new abilities for engineering biology, promising leaps forward with beneficial applications. At the same time, these advances raise concerns about biosecurity. Recently, Wittmann et al. described an in silico

Eave and Vent Experiments (EaVE) Phase A

June 18, 2025
Author(s)
Christopher Brown, Alexander Maranghides, Giovanni Di Cristina Torres, Diana Bailey, Lucy Fox, Eric Link, Selvarajah Ramesh, Monica Flores, Shonali Nazare, J. Houston Miller, Erin McCaughey
This report documents a series of full-scale fire experiments conducted at the National Institute of Standards and Technology (NIST) to characterize the performance of select wildland-urban interface (WUI) eave vents exposed to fire from noncombustible

Surface Wrinkling of Plasma-Exposed PDMS is Caused by Water Vapor Sorption: An Optical Environmental Sensor

June 18, 2025
Author(s)
Jack Douglas, Zain Ahmad, Tyagi Tyagi, Shuning Xiang, Jerry Heng, Pedro Patricio, Paulo Teixeira, Christopher Stafford, Joao T. Cabral
Wrinkling of polydimethylsiloxane (PDMS) has unlocked a plethora of technological applications, from tunable surface wetting to photonic response. Surface undulations with prescribed wavelength and amplitude are excited by in-plane mechanical compression

Demonstration of dispersion gas barometry

June 17, 2025
Author(s)
Yuanchao Yang, Jack Stone, Patrick Egan
Realization of the optical pascal has been limited by systematic errors caused by distortion of the optic. In this work, distortion error is circumvented via synchronous measurement of helium refractivity at two optical frequencies. The resultant pressure
