The retina is an eye structure that receives light from the environment and converts it to neural signals for the initiation of vision. When a human retina is damaged, a thin cell layer behind the retina – the retinal pigment epithelium (RPE) – responds to the injury by creating a scar that results in loss […]
CSIII-01: Uncovering the Newt’s Regenerative Secrets
Over 14 million people in the United States are currently living with cancer, a disease not limited to humans. In fact, several other animals elicit the growth of tumors when exposed to cancer-causing compounds commonly referred to as carcinogens. However, the newt, a type of salamander, can remain cancer-free when exposed to carcinogenic substances at […]
C14: Expanding upon the potential of a common breathalyzer sensor
The tin oxide electrochemical sensor is the active component in the personal breathalyzer used for ethanol detection. The sensor works by ethanol vapor reacting with oxygen species adsorbed to the SnO2 surface, then releasing trapped electrons back into the conduction band which changes the output voltage. However, to the best of our knowledge, the analytical […]
C35: The functionality of vocal communication in lowland woolly monkeys (Lagothrix lagotricha poeppigii) from the Tiputini Biodiversity Station, Ecuador
In group-living primates, vocal communication is critical for social interactions, maintaining contact with group members, avoiding confrontations with individuals in other groups, and evading predators. For this study, we investigated the vocalization patterns of wild woolly monkeys from the Tiputini Biodiversity Station in Amazonian Ecuador. We combined behavioral data previously collected in 2014 and 2015 […]
B26: Controlling the Twist Sense of ortho-Phenylene Foldamers
In nature, oligomers and polymers fold to generate intricate three-dimensional structures, yielding macromolecules with diverse functions including transport, catalysis, signal-recognition, and charge- and energy-transfer. Over the years, a wide variety of abiotic foldamers have been developed, ranging from non-natural peptides to aromatics. The ortho-phenylenes represent a recent addition to the family of aromatic foldamers. Systematic […]
B27: Synthetic Food Additives: Chemistry, Health Effects, and the Societal Dilemma
Have you ever been puzzled by complex-sounding ingredients on your food label, wondering why they are used and what they do? Synthetic additives are ubiquitous in today’s commercial food products, and their definitions, uses, and regulation are surprisingly complex. Today, many categories of synthetic additives exist, designed to improve food’s characteristics or manufacturing processes. Various […]
A57: Producing Ceramic Materials as an Alternative Recycling Method for Mine Waste Remediation
In an ever-growing world that continues to develop, there is an increasing demand for resources to be discovered, processed, and manufactured. Industries mine for valuable resources such as gold, silver, and copper to produce the infrastructure and goods that have become a necessity. To obtain and increase the quality of resources mined, the sought-after elements […]
C97: The transient assembly of supramolecular hosts of tetraethylene glycol and pentaethylene glycol diacids fueled by EDC
A dissipative system is a thermodynamically open system which is operated out-of thermodynamic equilibrium in an environment with which it exchanges energy and matter. which is characterized by the spontaneous appearance of symmetry breaking and the formation of complex, sometimes chaotic, structures where interacting particles exhibit long-range correlations. As stated in the BESAC report Challenges […]
B28: Separation and Characterization of Polyphenols in Salix Pulchra for Future Isotopic Studies
The availability of C13 labeled willow tissue (Salix pulchra) has pushed the need for extraction and characterization of polyphenolic compounds within the plant. A method of separation and purification of tannin from the willow plant has been established, but the identity of the extractable non-tannin polyphenols present in willow is not currently known. In order […]
B16: Effects of Earthworm Exclusion on Soil Microbial Activity
Earthworm activities alter soil structure, microbial activity, and nutrient availability in ecosystems colonized by earthworms compared to those lacking earthworms. Where earthworm populations are abundant, their activities increase surface leaf litter decomposition, and mixing of surface litter into the soil by earthworms and likely provides organic matter that enhances soil microbial activity. However, seasonal and […]
