Performing Skin Microbiome Research: A Method to the Madness

March 1, 2027
Author(s)
Heidi H. Kong, Bj?rn Andersson, Thomas Clavel, John E. Common, Scott Jackson, Nathanael David Olson, Julia Segre, Claudia Traidl-Hoffman
Growing interest in microbial contributions to human health and disease has increasingly led investigators to examine the microbiome in both healthy skin and cutaneous disorders, including acne, psoriasis, and atopic dermatitis. The need for common

Chemical characteristics of indoor aerosol particles and surface films

July 8, 2024
Author(s)
Rachel O'Brien, Cate Shirilla, Amy Hrdina, Emily Legaard, Kathryn Mayer, Marina Vance, Dustin Poppendieck, Delphine Farmer
Indoor surfaces and the films on them play important roles in indoor air quality due to the high surface area to volume ratios in our homes. The chemical complexity of these films can be large, and this can increase after film formation as the chemicals in

Impacts of Aging and Relative Humidity on Biomass Burning Smoke in an Indoor Environment

July 8, 2024
Author(s)
Marina Vance, Liora Mael, Sofie Schwink, Kathryn Mayer, Thomas Dunnington, Maximilian Schmid, Nicholas Gotlib, Andrew Martin, Dustin Poppendieck, Delphine Farmer
We studied the impacts of aging and relative humidity on simulated wildfire smoke in a test house during the Chemical Assessments of Surfaces and Air (CASA) study. We injected fresh and ozone-aged biomass burning smoke into the test house during times of

NIST Greenhouse Gas Measurements Program: A Decade of Critical Accomplishments

June 5, 2024
Author(s)
James Whetstone, Tamae Wong, Hratch Semerjian
At COP 21 (Paris), there was general agreement that programs to reduce greenhouse gas emissions and mitigate atmospheric warming will require an understanding of existing emissions as well as programs to monitor, report, and verify emissions from a broad

Research on Fixture-Level Peak Probability of Water Use in Commercial Buildings

June 5, 2024
Author(s)
Tao Li, Steven Buchberger, Toritseju Omaghomi, Gary Klein, William M. Healy
novel wireless sensor network is developed and demonstrated for monitoring indoor fixture level water use in buildings. The new technology consists of a low-cost, battery-powered, miniature wireless sensor module for non-invasive detection of flow through

Comprehensive Overview of Bottom-Up Proteomics using Mass Spectrometry

June 4, 2024
Author(s)
Yuming Jiang, Devasahayam Rex, Dina Schuster, Ben Neely, German Rosano, Norbert Volkmar, Amanda Momenzadeh, Trenton Peters-Clarke, Susan Egbert, Simion Kreimer, Emma Doud, Oliver Cook, Amit Yadav, Muralidharan Vanuopadath, Martin Mayta, Anna Duboff, Nicholas Riley, Robert Moritz, Jesse Meyer
Proteomics is the large scale study of protein structure and function from biological systems through protein identification and quantification. "Shotgun proteomics" or "bottom-up proteomics" is the prevailing strategy, in which proteins are hydrolyzed

Standards and Performance Metrics for On-Road Automated Vehicles

June 4, 2024
Author(s)
Craig I. Schlenoff, Zeid Kootbally, Prem Rachakonda, Suzanne Lightman, Apostol Vassilev, David A. Wollman, Edward Griffor
On September 5–8, 2023, the National Institute of Standards and Technology (NIST) held the second Standards and Performance Metrics for On‐Road Automated Vehicles Workshop. This four‐day virtual event provided updates on NIST's recent work in automated

Identification of Candidate Protein Biomarkers Associated with Domoic Acid Toxicosis in Cerebrospinal Fluid of California Sea Lions (Zalophus californianus)

May 28, 2024
Author(s)
Gautam Ghosh, Ben Neely, Alison Bland, Emily Whitmer, Cara Field, Padraig Duignan, Michael Janech
Since 1998, California sea lion (Zalophus californianus) stranding events associated with domoic acid toxicosis have consistently increased. Currently there are no practical non-lethal clinical tests for the diagnosis of domoic acid toxicosis (DAT) that

Optical n(p, T_90) measurement suite 2: H_2O and D_2O

May 28, 2024
Author(s)
Patrick Egan, Yuanchao Yang
A suite of measurements of refractive index n(p, T_90) is reported for gas phase ordinary water H_2O and heavy water D_2O. The methodology is optical refractive index gas metrology, operating at laser wavelength 633 nm and covering the range (293 T_90 43

Letter to the editor: Unit one is intrusive

May 24, 2024
Author(s)
David W. Flater
The SI brochure's treatment of quantities that it regards as dimensionless, with the associated unit one, requires certain physical quantities to be regarded as simply numbers. The resulting formal system erases the nature of these quantities and excludes

Mixture effects of PFAS on embryonic and larval sheepshead minnows (Cyprinodon variegatus)

May 22, 2024
Author(s)
Philip Tanabe, Peter Key, Katy Chung, Emily Pisarski, Jessica Reiner, Alix Rodowa, Jason Magnuson, Marie DeLorenzo
Per- and polyfluoroalkyl substances (PFAS) are ubiquitous and persistent environmental contaminants originating from many everyday products. Perfluorooctane sulfonic acid (PFOS) and perfluorooctanoic acid (PFOA) are two PFAS that are commonly found at high

Observation of a promethium complex in solution
