All Eyes and Ears: How Visual Deprivation Enhances Auditory Learning in Adult Mice

Mariam Malik ‘22 Past research and work has proven the interconnectedness of all senses and their corresponding cortices in the brain. For example, it has been scientifically proven that those lacking in one sense possess advanced abilities in others. Cross-modal learning, or the manipulation of one sense to cause alterations in another, is a key feature of further research. Researchers at the University of Maryland … Continue reading All Eyes and Ears: How Visual Deprivation Enhances Auditory Learning in Adult Mice

Big-Hearted: Arrhythmia in the World’s Largest Living Animal

Mariam Malik ‘22 Bradycardia is a slower-than-normal heart rate, and can vary depending on age and physical condition. According to the American Heart Association, a heart rate lower than sixty beats per minute (BPM) qualifies as bradycardia. Tachycardia, on the other hand, is a heartbeat that is too fast, specifically one that beats over a hundred times per minute. Both conditions vary by age and … Continue reading Big-Hearted: Arrhythmia in the World’s Largest Living Animal

21st Century Mind: The Effects of Blue-Light on the Brain, Retinas, and Rate of Aging

Mariam Malik ‘22 Blue light from electronic devices, such as smartphones and laptops, is of shorter wavelength on the light spectrum, thereby giving off higher amounts of energy. The harmful effects of absorbing too many light rays, such as UV and micro, have been researched and known. However, a recent study at Oregon State University on Drosophila melanogaster, the common fruit fly, shows the damaging … Continue reading 21st Century Mind: The Effects of Blue-Light on the Brain, Retinas, and Rate of Aging

Study Reveals Ability of Human Cartilage to Regenerate

Mariam Malik ‘22 Cartilage is malleable soft tissue meant to prevent excess friction from joints rubbing against one another. Located in numerous parts of the body, such as the larynx, respiratory tract, and the septum, human cartilage is the most malleable and widespread at birth, eventually being replaced by bone. For a long time, scientists believed that cartilage in joints could not be regrown; however, … Continue reading Study Reveals Ability of Human Cartilage to Regenerate

Changes in Retinal Chromatin Allow Animals To Be Nocturnal

Mariam Malik ‘22 Night vision allows nocturnal animals to be active at nighttime and sleep when the sun is out, while diurnal animals are active during the day and sleep at night. However, when both diurnal and nocturnal animals are born, their ocular abilities are equal until a change in the cells of the eye occurs, allowing the animal to see in the dark. Through … Continue reading Changes in Retinal Chromatin Allow Animals To Be Nocturnal

Tfh13: The Cells Involved In An Allergic Reaction

Mariam Malik ’22 Anaphylaxis is the biological reaction of the body to an allergy, in which airways are constricted and blood pressure suddenly drops. Anaphylactic shock can result from various allergies, including food and insect stings. Previous research has shown that during an allergic reaction, the immune system releases high levels of high-affinity Immunoglobin (IgE) antibodies, which then strongly bind to allergens to form an … Continue reading Tfh13: The Cells Involved In An Allergic Reaction
