Bio-Diesel Enhances the Flow of Emulsions in Pipelines

by Jenna Mallon (’18) Emulsions, mixtures containing two immiscible liquids, are used in a variety of industries including food, paint, pharmaceutical, cosmetic, and oil/gas. Emulsions play a large role in petroleum production since they exist at every stage of production, from crude oil to the refined petroleum. Issues arise when it comes to the transport of petroleum: the emulsions in the petroleum may contain solids … Continue reading Bio-Diesel Enhances the Flow of Emulsions in Pipelines

The Impact of Climate on Crime Rates

by Julia Newman (’19) Previous data has shown that overall levels of aggression increase as you move closer to the equator, with Central America showing a murder rate over twenty people greater than that in European countries, but a definitive reasoning has yet to be found. Scientists have suggested that high temperatures cause increased heart rate and blood pressure leading to anger; others have pointed … Continue reading The Impact of Climate on Crime Rates

Small-Scale Modeling Shows Influences on Climate Change

by Jenna Mallon (’18) Due to their low-latitude location, Mesoamerica and the Caribbean are at particularly high risk of experiencing the effects of climate change. There are currently many global models that show the effects of climate change on a large scale, but fail to take into account the effects that topography and land use have on temperature and precipitation.  This prompted Robert Oglesby, of … Continue reading Small-Scale Modeling Shows Influences on Climate Change

Researchers Find Correlation Between Pollen Storages and Foraging Activity

by Jenna Mallon (’18) A lot goes on inside the hives of Apis mellifera, commonly known as the western honeybee, to keep the colony of bees alive and healthy. Forager bees work outside the hive to collect water, pollen, nectar, and resin: all of which are necessary for the survival of the bees. Collecting pollen and understanding the behavior and action of forager bees has … Continue reading Researchers Find Correlation Between Pollen Storages and Foraging Activity

The Origin of Dogs Traces Back to Two Separate Locations

by Jenna Mallon (’18) Although it is a common fact that domestic dogs originated from wolves, there are still speculations concerning the geographical and temporal origins of man’s best friend. There are disagreements over when and where dogs were domesticated. Despite evidence that points to the Paleolithic Era, some archeologists argue that dogs could have been independently domesticated in two separate regions: Eastern and Western … Continue reading The Origin of Dogs Traces Back to Two Separate Locations

Filtering Power Plant Exhaust with a CO2 Fastlane

By Meghan Bialt-DeCelie ’19   With the increasing amount of carbon dioxide gas contributing to global climate change, scientists are struggling to find strategies to reduce it. The usage of hybrid polymer-MOF membranes is being explored as a possible strategy because of their energy and cost efficiency in comparison to previous methods of gas separation. However, these membranes need to be improved in their carbon dioxide … Continue reading Filtering Power Plant Exhaust with a CO2 Fastlane

2015 Named Hottest Year on Record

By Shannon Bohman ’19 The National Oceanic and Atmospheric Association reported that 2015 has replaced 2014 as the hottest year on historical record. An unusually large El Niño pattern in the Pacific Ocean contributed to these record temperatures. However, most of this can be explained by global warming created due to the emission of greenhouse gases. As the atmosphere warms, it holds more water vapor. … Continue reading 2015 Named Hottest Year on Record

Groundbreaking Fossil Transforms Current Evolution Views

By Surya Chalil Gondwanatheria is an extinct group of mammals that has only been known through a few isolated teeth and fragmented jaw pieces. As a result, their clade largely remained a mystery and their placement among the evolutionary tree was uncertain and debatable. However, Stony Brook University paleontologist, David Krause, Ph.D., led the research team that discovered an almost complete cranium of a new … Continue reading Groundbreaking Fossil Transforms Current Evolution Views
