"The skin is the interface between the human body and the environment, and the different features in distinct skin regions, such as different temperatures, humidity levels, gland densities, and pH values, create a variety of niches that can support a diverse skin microbiome. This microbiome includes bacteria, archaea, viruses, fungi, and even mites. A healthy skin microbiome helps maintain skin homeostasis, protects against pathogens, communicates with and trains the immune system, and affects wound healing. However, the skin microbiome can be influenced by many factors, including intrinsic factors like aging and extrinsic factors like cosmetic. Recent advances in molecular biology techniques and next-generation sequencing have drastically increased our understanding of the microorganisms that live on our skin, but the microbes are often still difficult to culture and study..."

In this assignment students receive six air photos of a 4 km stretch of Fountain Creek in El Paso Country, Colorado (38.7 N, 104.715 W) taken between 1989 and 2006 and are asked to evaluate and discuss how Fountain Creek has changed through the years. The main nuts and bolts of the assignment are an analysis of these repeat air photos and production of a map that depicts how the course of the river (or its cut-banks, point bars and bank-to-bank width) changes through time. To make this map, students can use trace paper/Mylar, or software such as ArcGIS or Adobe Photoshop or Illustrator, but whatever their method they use they need to be able to establish a scale allowing them to measure and calculate rates of change. What change to quantify is purposely left open ended - students typically focus on measuring rates of cut-bank erosion, point bar migration, bank-to-bank width changes, channel length or sinuosity variation over the prescribed study area - and is usually linked directly to what they decide to map, such as the course of the river or the extent of the 'active' channel. After producing their map and making measurements, the final part of the assignment is synthesis. In the final questions, students are asked to summarize and describe in words what's happening to the channel through time, with reference to their map and calculations, and to consider the environmental conditions that are driving the changes observed.

"Spaceflight affects the human body in numerous ways, but one underexplored area is the mouth. The mouth is home to rich populations of bacteria and fungi which, studies have hinted, can undergo shifts during long and even short space missions. For the first time, researchers have tracked changes in the oral microbiome during and after spaceflight and examined how those changes might reawaken dormant viruses — a phenomenon long known to affect astronauts. The team analyzed saliva samples from 10 male astronauts for microbial makeup and for the presence of Epstein-Barr, herpes simplex, and varicella zoster virus. Only Epstein-Barr virus counts appeared to track with changes in microbial composition during spaceflight. For example, increased virus counts coincided with increased numbers of bacteria of the genus Gracilibacteria, while low counts coincided with increased numbers of members of Oribacteria and Hemophilus..."

"Many factors affect the evolution of species, but a new influence has recently been recognized. Gut microbes – tiny residents of the intestinal tracts of all animals – have wide-ranging effects on the physiology of their hosts and scientists are increasingly appreciating that diversification may actually be correlated with changes in the gut microbiota. However, the extent to which gut microbes evolve along with a host species remains unclear. A recent study examined this correlation using an ideal model – a system where evolution repeated itself in different geographic settings. Beginning with two groups of Nicaraguan cichlid fish that evolved in parallel in different crater lakes researchers sequenced microbes from fish guts and lake water to determine whether species diverged in parallel. They found that bacterial communities in fish were distinct from those in lake water..."

In this course, students will develop their abilities to expose ways that scientific knowledge has been shaped in contexts that are gendered, racialized, economically exploitative, and hetero-normative. This happens through a sequence of four projects that concern:
Interpretation of the cultural dimension of sciences Climate change futures Genomic citizenry Students’ plans for ongoing practice
The course uses a Project-Based Learning format that allows students to shape their own directions of inquiry in each project, development of skills, and collegial support. Students’ learning will be guided by individualized bibliographies co-constructed with the instructors, the inquiries of the other students, and a set of tools and processes for literary analysis, inquiry, reflection, and support. Acknowledgement Professor Peter Taylor spent several years crafting the unique structure of the course, which is crucial to the way it was taught. The Consortium for Graduate Studies in Gender, Culture, Women, and Sexuality This course was taught as part of the Consortium for Graduate Studies in Gender, Culture, Women, and Sexuality (GCWS) at MIT. The GCWS brings together scholars and teachers at nine degree-granting institutions in the Boston area who are devoted to graduate teaching and research in Women’s Studies and to advance interdisciplinary Women’s Studies scholarship.

"Walking through the produce section at the grocery store, you are likely to find tomatoes of all shapes, sizes, and colors. One variety may be large and oblong with a hint of bitter flavor while another will have small, sweet fruits. This variance is primarily the result of genetic and chemical properties of the different varieties. But it turns out, environment also plays a role. A team of Italian scientists has shown that the molecular properties of tomatoes are strongly influenced by environmental factors such as temperature and moisture. And changing these factors can, in turn, have pronounced effects on the physical and culinary qualities of the fruits – an important finding considering the pace of current climate change. To tease apart the interaction between genetics, environment, and organoleptic traits, the research team grew three tomato varieties in two different locations. This exposed the plants to varying levels of moisture, soil acidity, and temperature, among other conditions..."
