Complexin induces a conformational change of the SNARE complex

by Aaron Gochman (’18) Intercellular communication in the central nervous system occurs at a synapse, the gap between two neurons. The presynaptic neuron releases a chemical messenger known as a neurotransmitter, which diffuses across the synapse and relays the signal to the postsynaptic cell. The process of releasing the neurotransmitter from the presynaptic cell is quite complicated. The mechanism includes packing the neurotransmitter inside a … Continue reading Complexin induces a conformational change of the SNARE complex

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

Dual Threat: DLK as a Novel Role Player in Axonal Regeneration

by Aaron Gochman (’18) Axonal regeneration is a branch of neuroscience on the cutting edge; re-growing injured neurons is a technique that, once refined, will fundamentally change the landscape of nervous system therapies. A team of researchers from University of Michigan, Washington University in St. Louis, and University of Pennsylvania have discovered a key intracellular pathway in axonal regeneration that is conserved in both Drosophila, … Continue reading Dual Threat: DLK as a Novel Role Player in Axonal Regeneration

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

Chromosomal Studies Lead to Advancements for Alzheimer’s Disease

by Sahil Rawal (’19) Alzheimer’s disease is a well-known neurodegenerative disease that commonly affects people of older age. Although scientists have been able to connect different lifestyle factors with the onset of Alzheimer’s, the basic molecular mechanisms are still not completely understood. Currently, there are many ongoing studies that aim to gain more information on Alzheimer’s disease and the etiologies behind the devastating disease. Studies … Continue reading Chromosomal Studies Lead to Advancements for Alzheimer’s Disease

The Secret Behind Increased Wisdom

by Lillian Pao (’18) There is no concrete definition of wisdom. However, there are some repetitive themes that encompass the idea of wisdom, such as the use of knowledge from an experience, careful decision-making, and lowered anxiety during complex situations. In a recent study, professors of the University of Chicago concluded that there may be a connection between somatic, or physical, practices and wisdom. Although … Continue reading The Secret Behind Increased Wisdom

Swimming Pools May Be Mutagenic

By Sahil Rawal (’19) Swimming pools are known to contain many disinfectant products such as chlorine to keep the water safe to swim in. However, studies have recently found that these disinfectants release byproducts that could eventually react with organic matter already present in the water, such as human urine or sweat. These released byproducts have already been found to cause cases of asthma and … Continue reading Swimming Pools May Be Mutagenic

The Moon and its Effects on Sleep and Behavior

By Lillian Pao (’18)               For centuries, the mythical powers of the moon and its influence over human behavior have fascinated mankind. Because of this fascination, an international group of scientists decided to test whether the lunar phases affected children’s sleeping patterns. The full moon, half moon, and new moon were the three lunar phases that were tested. Over … Continue reading The Moon and its Effects on Sleep and Behavior

The Health Consequences of Eating Potatoes

by Sahil Rawal (’19)   Potatoes have been a staple in our diet for a very long time; they were recently added to the US healthy meals program after they were shown to increase potassium levels and lower blood pressure. Despite this, the effect of increased consumption of potatoes on blood pressure is still unclear. As a result, researchers from Brigham and Women’s Hospital decided … Continue reading The Health Consequences of Eating Potatoes

Loss of Reefs Traced Back to Carbon Dioxide Levels

By Julia Newman ’19 As the growth of limestone in coral reefs slows, their ecosystems are drastically reduced in terms of size and diversity. This is a natural cycle that occurs in autumn and winter each year due to the decrease in water temperature and light during those months; the corals that represent much of these reefs are usually able to produce enough limestone to make up for … Continue reading Loss of Reefs Traced Back to Carbon Dioxide Levels

DNA Packing Mechanisms in Viruses Revealed

by Julia Newman ’19 New studies on the packing of DNA in viruses show that it sometimes behaves like a fluid and other times like a solid, similar to a tube of toothpaste or a cup of sand. For this reason, it was difficult in the past for scientists to determine how DNA is packed within a viral shell. However, it turns out that viruses actually have a … Continue reading DNA Packing Mechanisms in Viruses Revealed

Baboon Case Study Furthers Transplant Research

By Julia Newman ’19 Eight thousand people in the United States die each year while waiting for a viable heart transplant, but recent baboon studies suggest that scientists may one day be able to drastically decrease this statistic. Finding enough human organ donors can be extremely difficult, which has led researchers to investigate cross-species transplants within the last few decades. However, given that many donated … Continue reading Baboon Case Study Furthers Transplant Research
