"Actinobacteria are some of the most widely distributed bacteria in soils and are well known for their ability to degrade plant residues in pure culture in the laboratory. Yet, despite the importance of microbe-driven decomposition to carbon sequestration in terrestrial systems, their importance and specific activity across diverse environments in the field are unknown. Researchers recently evaluated the ecophysiological roles of Actinobacteria in rice straw residue decomposition in a series of field and microcosm experiments. They found that although Actinobacteria represented only 4.6% of the total bacterial abundance, they encoded 16% of the total carbohydrate-active enzymes (CAZymes) involved in the breakdown of carbohydrates. The researchers also found that Actinobacteria taxonomic and functional compositions were relatively stable during straw decomposition and that the importance of Actinobacteria in decomposition increased as soil fertility decreased..."

Using the article "Stop Raising Awareness Already" by Cristiano and Neimand and …
Using the article "Stop Raising Awareness Already" by Cristiano and Neimand and a six-step template, students create a plan to show how they apply the knowledge learned throughout the term to make a broader impact. The students are asked to very narrowly choose a single action they want a group of stakeholders to take and develop a multiple-step plan to accomplish the action. The students are required to select and justify a targeted stakeholder, develop an action, identify a messenger that can influence their targeted stakeholder to take the action, develop a sticky message relating the "ask" to the goal of the campaign, and document their key assumptions imbedded in their action plan.

This assignment is a 10-hour, out-of-class project where each student designs and carries out an action plan to enhance sustainability. Students select from a large suite of alternative actions, most of which can be quantified for reductions in CO2 and energy consumption, as well as in dollar savings.

"Humans rely on microbial communities in both natural and applied settings. One such applied setting is wastewater treatment plants, which use microbial communities to remove pollutants. However, the stability of the taxonomic diversity in these settings is not well understood. To close this gap, researchers examined how the microbial community in activated sludge changed over time in a full-scale wastewater treatment plant. For the first 3 years of a 9-year series, the microbial community fluctuated around a stable average. Then a bleaching event, marked in red under the timeline, abruptly pushed the community to an alternative stable state, where the originally dominant Actinobacteriota were disproportionally depleted and replaced with Proteobacteria, but these taxonomic changes led to little change in either the metabolic profile of the community or system performance. In a fine-scale analysis of dynamics, the researchers identified cohorts that dominated at different periods..."

"Acute myeloid leukemia (AML) is a type of blood and bone marrow cancer with a low survival rate. One reason AML is so deadly is because it can evade the immune system, in part by downregulating proteins like MICA, which normally marks damaged or cancerous cells in the body for immune destruction. To improve treatment prospects, researchers recently searched for molecules that can restore MICA levels in AML cells. They found that the transcription factor KFL4 is involved in MICA expression. In addition, treating cultured AML cells with the KLF4-activating compound APTO253 successfully induced MICA expression, while inhibiting the expression of the cancer gene MYC. These changes made the AML cells more susceptible to being killed by immune cells. Although studies in animals and humans are still needed, these findings reveal that APTO253 can improve immune cells’ ability to detect and kill AML cells and suggest that targeting KFL4/MICA is a promising option for AML treatment..."

By far most field trips in structural geology and regional tectonics do NOT take place in large urban centers with a trip focus on mitigation of hazards. What is described here is an example of the instructional and learning opportunities associated with active tectonic examination of large population centers.

"In northern ecosystems, winter carbon loss is estimated to exceed growing season carbon uptake, primarily because of microbial decomposition. Viruses in soil alter microbial carbon cycling by affecting metabolic pathways and killing their hosts, but whether viruses are active under anoxic and sub-freezing soil conditions remains unknown. To find out, a recent study used stable isotope probing (SIP) targeted metagenomics to investigate active microbes in Alaskan Arctic peat soils under simulated winter conditions, with a particular focus on viruses and virus-host dynamics. Overall, 46 bacterial and 243 viral populations actively took up soil water labeled with ¹⁸O and respired CO₂. Active bacteria represented a small proportion of the total microbial community but were able to ferment and degrade organic matter. In contrast, a large diversity of viruses were found to be active, one-third of which were linked to active bacteria..."
