Mammalian Brain Affected by Non-Genetic and Allele-Specific Expression

By Rideeta Raquib ’19 The brain is a complex organ that is constantly being impacted by genetic and epigenetic factors. Mental illness patients are usually heterozygous in terms of inheriting one mutant allele. The random inactivation of the X-chromosome and genomic imprinting influences brain architecture and risk of disease. Studies on neuropsychiatric disorders uncovered a spectrum of data regarding the epigenetic dynamics of such dysfunction. … Continue reading Mammalian Brain Affected by Non-Genetic and Allele-Specific Expression

Reduction of Type 2 Diabetes Via Weight Loss Drug

By Rideeta Raquib ’19 Prediabetes, also known as “borderline diabetes,” is a condition common among people with obesity who have increased blood sugar levels. Although it can eventually lead to type 2 diabetes, prediabetes can be cured through exercise and diet changes. In 2012, 86 million Americans of age 20 years or older had prediabetes. A drug, named Liraglutide 3·0 mg, can reduce body weight … Continue reading Reduction of Type 2 Diabetes Via Weight Loss Drug

Using Positive Image Training to Regain Happiness

By Rideeta Raquib ’19 Emotion-related imagery training is a powerful tool for psychotherapy. Mental imagery can stimulate behavioral and physiological systems more effectively than verbal or informative stimulations. Imagery is less effective on patients diagnosed with generalized anxiety (GAD) because of the tendency to associate bright images with negative occurrences rather than generating positive images. Dr. Svetla Velikova and her team of researchers conducted a … Continue reading Using Positive Image Training to Regain Happiness

Fat Metabolism Activated by Brain Hormone

By Rideeta Raquib ’19 The central nervous system is essential in regulating different parts of the body. Serotonin (5-hydroxytryptamine, 5-HT), a neuromodulator, has been related to feeding and metabolizing, as well as burning fat. Biologists at the Scripps Research Institute set out to identify a neuropeptide ligand and its cognate receptor that makes up the 5-HT neuroendocrine axis. The study was conducted on a roundworm … Continue reading Fat Metabolism Activated by Brain Hormone

Creating a Living Bio-Hybrid System

by Rideeta Raquib ’19   Neurons are a remarkable aspect of living organisms that enable electrical signals to travel to the brain and back, this translates to voluntary and involuntary responses. Designing a functional system that could mimic the actions present in the brain has proved to be an obstacle for many researchers. The most tedious aspect of such a design is to model the learning … Continue reading Creating a Living Bio-Hybrid System

Erasing Fear via Reconditioning of the Brain

by Rideeta Raquib ’19 Fear is an unpleasant emotion that can cause someone to be afraid. Although a small amount of fear has been evolutionarily helpful to organisms for preventing predation, too much fear can be mentally harmful. In fact, phobias and post-traumatic stress disorders can negatively impact the daily lives of many people. A study conducted by neuroscientists from the University of Cambridge, Japan, and … Continue reading Erasing Fear via Reconditioning of the Brain

Toxic Hazards from Smartphones

by Rideeta Raquib ’19   Smartphones are an integral part of today’s society, but they are also a huge fire hazard. Lithium-ion batteries, commonly used in rechargeable devices, have a reputation of being susceptible to combustion. Dr. Jie Sun from the Institute of NBC Defense and the Tsinghua University in China collaborated to study the deleterious emissions of Li-ion batteries or LIBs. Two types of LIBs … Continue reading Toxic Hazards from Smartphones

Frog Skin Contains Chemicals That Repel Ants

by Rideeta Raquib ’19   Several species, such as the Lutjanus bohar fish species, have the ability to camouflage themselves to avoid predators. This allows them to have a selective advantage in their respective environments compared to other species. Dr. Andre de Lima Barros, from the National Institute of the Amazonian Research in Brazil, hypothesized that Lithodytes lineatus, a species of frog prominent in the Amazon … Continue reading Frog Skin Contains Chemicals That Repel Ants
