No full textFarm News, July 22, 2020: I want to introduce you all to our wonderful line of microgreens and explain a little about these wonderful addition to our veggies. Microgreens are young vegetable greens that are grown from seed in our greenhouse and cut at no more than 3 inches in length. We have chosen varieties that provide fast consistent growth and offer great aromatic flavor

No full textFarm News, August 19, 2020: Wow, it was a hot week! What a roller coaster ride this summer has been. Last week we had highs in the 70's and a night with a touch of frost, and then full heat and maximum lows not falling below 75. We'd prefer the cooler temperatures to work but the crops that had a slow start back in June have gotten a good boost. We've been busy harvesting almost everyday to stay up with the maturing crops. We have a nice supply of Walla Walla Onions and will be moving into getting the yellow onions out of the field next
Maximizing Costs to Prevent Antibiotic Resistance Evolution
No full textThe increasing prevalence of antibiotic resistance among bacteria continues to threaten current and future human health. One possible strategy for managing antibiotic resistant bacteria may be to prevent the evolution of antibiotic resistance in the first place. Such a strategy may rely on exploiting trade-offs. Trade-offs require bacteria to sacrifice their ability to survive in one environment in order to adapt to another. Bacteria are less likely to acquire adaptations that require a tall sacrifice or “cost” relative to adaptations with lower costs. Antibiotic resistance is associated with many trade-offs and costs. However, the magnitude of its costs can vary dramatically between bacterial populations. Understanding the factors that increase costs may help limit the evolution of antibiotic resistance. Artificial evolution experiments and preliminary undergraduate research suggest that variation in costs is influenced by three sources: environmental variation, genetic variation, and genotype-by-environment interactions. Some experimental medical treatments, like multidrug or phage therapies, may be able to manipulate these sources to prevent the evolution of antibiotic resistance. Future research objectives regarding antibiotic resistance should focus on how interactions between bacteria, genetic correlations, and genotype-by-environment interactions influence the costs of antibiotic resistance
