Facial Expressions Of Humans And Dogs Are Not The Same
By Maryna Mullerman ’20 Mammalian facial expressions are known to correlate with animals’ internal states. Substantial similarities have been previously identified between chimpanzees and humans, but facial expression similarities between more distant mammalian species is unknown. Caeiro Cátia and researchers from the University of Lincoln in the United Kingdom investigated whether domestic dogs produced certain facial expressions in response to different external emotional stimuli. Furthermore, … Continue reading Facial Expressions Of Humans And Dogs Are Not The Same
The Effects Of Implicit Racial Bias On Hand Ownership Experience
By Maryna Mullerman ’20 Rubber hand visual-tactile illusion (RHI) experiments involve multisensory exposure, allowing participants to experience ownership over realistic rubber hands. Precise stimulation technique and positioning induce people to believe that a rubber hand is an integral part of their body. Marilia Lira and researchers from the Mackenzie Presbyterian University in Brazil investigated skin color’s effects on the time to onset of RHI in … Continue reading The Effects Of Implicit Racial Bias On Hand Ownership Experience

Age Is No Barrier For Academic Success
By Maryna Mullerman ’20 Many studies have explored academic success predictors in young adults. In recent years, however, more people over the age of 60 have undertaken university educations. Abbie-Rose Imlach and researchers from the University of Tasmania in Australia hoped to identify cognitive, psychological, social, and genetic factors that influenced academic performance in older adults. The researchers hypothesized that factors such as genetic polymorphism, … Continue reading Age Is No Barrier For Academic Success
High Intensity Exercise Stimulates Memory
By Meenu Johnkutty ‘21 New research suggests that the long-term effects of high intensity exercise may prove to be more beneficial than previously thought. Many studies have demonstrated that aerobic exercise improves the structure and function of the hippocampus, the region of the brain responsible for learning and memory. Scientists posit that neurotrophic factors like insulin growth factor (IGF) and brain-derived neurotrophic factor (BDNF) are … Continue reading High Intensity Exercise Stimulates Memory
Positive Feedback Loop Implicated in Methane Emissions from Aquatic Environments
By Meenu Johnkutty ‘21 Scientists have long forewarned of the detrimental effects of climate change on the planet. Rising global temperatures coupled with the lack of due diligence in handling the environmental crisis have scores of ecologists worried about the many fragile ecosystems on the brink of a biodiversity crisis. A recent study conducted by researchers from Radboud University Nijmegen in the Netherlands provides new … Continue reading Positive Feedback Loop Implicated in Methane Emissions from Aquatic Environments
The Role of Oxytocin in Dogs’ Emotional Responses to Human Facial Expressions
By Meenu Johnkutty ‘21 Dogs are our friendly companions, our trusted partners in crime, and our constant cuddle buddies. Past studies have found that our facial expressions significantly affect dogs’ emotional responses, and that the “affection hormone” oxytocin is crucial in dogs’ regulation of social behavior and emotions. In a recent study, Finnish researchers at the University of Helsinki chose to research the effects of … Continue reading The Role of Oxytocin in Dogs’ Emotional Responses to Human Facial Expressions
Finding Conductive Proteins Using Scanning Tunnel Microscopy
By Meghan Bialt-DeCelie ’19 Single molecule detection techniques are used to understand the behaviors of a specific biological molecule and have applications in medical and pharmacological research. This can be critical for understanding how an individual biological molecule, such as a specific protein, functions, as well as its role in a biological pathway. Researchers led by Stuart Lindsay, PhD from Arizona State University found high … Continue reading Finding Conductive Proteins Using Scanning Tunnel Microscopy
Using Nanotechnology to Reduce Glare on Screens
By Meghan Bialt-DeCelie ‘19 Displays of all commonly used electronics such as smartphones, televisions, and laptops all suffer from glare on their glass surfaces. Glass and clear plastics are transparent, but they are still visible due to a small amount of reflection of light caused by the difference between the refractive index of the surface and the rest of the material. Antireflective coating and screens … Continue reading Using Nanotechnology to Reduce Glare on Screens
Electrical Stimulation Improves Memory in Epileptic Patients
By Meghan Bialt-DeCelie ‘19 For many animals and humans, a major region of the brain involved in memory formation is the hippocampus. Learning and memory is done through a neural process called long-term potentiation (LTP), and past research has shown that electric stimulation to the hippocampus can promote this process. Researchers led by Ali Titiz, PhD from The University of California Los Angeles found a … Continue reading Electrical Stimulation Improves Memory in Epileptic Patients
Daydreaming – A Possible Sign of Brain Efficiency
By Nita Wong ’21 In today’s fast-paced society, daydreaming carries a negative connotation. Whether it be in class or during a work meeting, a wandering mind is not considered a positive trait. Recent research, however, suggests that daydreaming may denote superior brain efficiency and capacity. A study led by Christine Godwin and Eric Schumacher of the Georgia Institute of Technology’s School of Psychology examined the … Continue reading Daydreaming – A Possible Sign of Brain Efficiency
The Selfish Brain: A Trade-off Between Cognitive And Physical Performance in Humans
By Maryna Mullerman ’20 The brain metabolizes more glucose — a simple and widely accessible sugar — than any other organ in the human body. Daniel Longman and researchers from the University of Cambridge in the United Kingdom explored the trade-off involving the brain and muscles, or physical performance, in people. The study investigated how mental and physical activities are affected when they are performed … Continue reading The Selfish Brain: A Trade-off Between Cognitive And Physical Performance in Humans
