Welcome to the beginning 4-H outdoor cooking project—S’mores and More! If you haven’t yet experienced the joys of cooking outdoors, here’s your opportunity to roast marshmallows, make your own S’mores, and so much more!
The goals of the Of People and Fish program are for youth and adults to understand the complex cultural and scientific history that has led to the “salmon crisis” and to become active citizens in the search for solutions within their communities.
Curriculum introduces adults and youth to the science and function of wetlands, streams and oceans, and how human activities affect climate and environmental function and health.
We report zero kinetic energy (ZEKE) photoelectron spectroscopy of benzo[h]quinoline (BhQ) via resonantly enhanced multiphoton ionization (REMPI) through the first electronically excited state S₁. From the simulated REMPI spectra with and without Herzberg–Teller coupling, we conclude that vibronic coupling plays a minor but observable role in the electronic excitation to...
Na⁺/H⁺ antiporters are ubiquitous membrane proteins that play a central role in the ion homeostasis of cells. In this study, we examined the possible role of Na⁺/H⁺ antiport in Yersinia pestis virulence and found that Y. pestis strains lacking the major Na⁺/H⁺ antiporters, NhaA and NhaB, are completely attenuated in...
Measurements of δ²H and δ¹⁸O in isotope-based field studies have fundamentally
improved our understanding of water flow and transport time scales in soils and headwater
catchments. Until recently, however, technical constraints have limited the temporal
resolution at which water samples could be collected and analyzed. We introduce a new
sample...
Infection with Helicobacter pylori is a major risk factor for the development of gastric cancer, and infection with strains carrying the virulence factor CagA significantly increases this risk. To investigate the mechanisms by which CagA promotes carcinogenesis, we generated transgenic zebrafish expressing CagA ubiquitously or in the anterior intestine. Transgenic...
