Panayiota Siskos ’23 Autoimmune thyroid diseases, such as Graves’ disease and Hashimoto’s disease, are often characterized by the infiltration of T cells and B cells in the thyroid as well as the production of antibodies specific to thyroid antigens. Genes including human leukocyte antigen (HLA), cytotoxic T lymphocyte-associated factor 4 (CTLA-4), CD40, and protein tyrosine phosphatase-22 (PTPN-22) have been previously associated with susceptibility to autoimmune … Continue reading Genetic factors may be involved in disease risk of early-onset autoimmune thyroid disease
Panayiota Siskos ’23 The theory of predictive coding states that the brain continuously creates a mental model of the surrounding environment using prior knowledge from memory. This mental model is then used to predict sensory input, such as anticipating a smell, a sound, or a touch. A group of researchers from Stony Brook University and Columbia University studied the effect of threatening cues on sensory … Continue reading Threatening cues have a larger effect on perception than neutral cues
Ashley Goland ’23 Solar geoengineering is a technology that aims to reflect incoming sunlight away from the Earth to reduce the rise of global temperatures, and one proposed approach is to send aerosols into the atmosphere. Although this method may seem like a quick, relatively cheap way to delay further climate change, the effects it could have upon marine and terrestrial organisms are not yet … Continue reading Implications of Solar Geoengineering
Ayesha Azeem ‘23 For centuries, humans have been breeding domestic dogs with the intention of producing specific skill sets needed to improve humans’ lives. For example, purpose-bred dogs can be used for hunting or as service dogs that guide people with disabilities. Dog breeding has been highly controversial lately, since dogs are now seen more as companions rather than workers. In a new study conducted … Continue reading Breeding can Change Dogs’ Brains
Ayesha Azeem ‘23 “Comfort-eating,” or increased food intake, is one of the most common responses to stressful situations. Cortisol is the body’s main stress hormone that regulates metabolism and the immune response to stressful situations. Cortisol reactivity under stress can predict stress-related eating behavior and how it affects the body mass index (BMI). Based on one’s cortisol reactivity to a stressor, a person may be … Continue reading Comfort Eating and Cortisol Reactivity
Simran Kaur ’20 Complete surgical resection of breast tissue, known as a mastectomy, is often suggested as the first-line treatment in patients diagnosed with breast cancer. Metastasis, the spread of cancer cells to other parts of the body, is a frequent occurrence after surgery and is the primary cause of cancer-related deaths. It was hypothesized by the researchers in this study that the type of … Continue reading Breast Cancer Metastasis Hypothesized to be Affected by Type of Administered Anesthesia
Priyanshi Patel ‘22 Metastasis refers to the surgical removal of solid tumors and metastasis is the main cause of cancer death. Previously, not much was known about the role anesthetics play in cancer metastasis. Complete surgical removal of solid tumors offers the possibility of a cure and is the basic treatment provided. Despite surgery, recurrent metastasis in vital organs does reoccur and is a major … Continue reading Different Types of Anesthesia can Impact Breast Cancer Metastasis.
Fatin Chowdhury ’20 The predisposition of organisms in seeking certain phenotypic traits in mates is an oft-observed aspect of the natural world, with sexual selection being a well-studied phenomenon. However, unique coloration specifically often seems to be more linked to lessened survivability (due to an inability to camouflage in environments), or phenomena such as aposematism, where unique colors serve as a warning for predators. In … Continue reading Examining the Benefits of Unique Coloration for Male Trinidad Guppies
Fatin Chowdhury ’20 Forests are stratified in sections such as the herbaceous layer, which includes tracheophytes (plants with vasculature) over 1 meter in height and can be extremely ecologically significant. Potential factors influencing forest dynamics in this context include top layer (overstory) characteristics and soil quality. A researcher at the University of West Florida, Frank S. Gilliam, recently conducted work at the Fernow Experimental Forest … Continue reading Herbaceous Layer Dynamics in Central Appalachian Hardwood Forests
Ayesha Azeem ‘23 We humans are very complex creatures. When we spend a lot of time in close association with a species, we tend to treat them as if they are humans as well, and we can decipher their emotions clearly. With the expression of emotions, we can communicate our motivations, responses and needs to others. Recognizing animals’ emotions can be beneficial, as it may … Continue reading How Do We Recognize Dog Emotions?
