Psychopathy is a constellation of distinct interpersonal (e.g., pathological lying), affective (e.g., lack of remorse), lifestyle (e.g., need for stimulation), and antisocial (e.g., poor behavioral controls) traits that contribute to a deceptive and exploitive personality profile. Current theoretical models attempting to explain the functional impairments and neural systems behind the behavioral profile of the disorder seem to converge on the idea of a fear deficit. The purpose of this essay was to investigate the positive relationship between psychopathy and fear deficits as well as the dysregulation of the limbic system in adults.
Characterized by a lack of empathy and increased antisocial and risk-taking behavior, psychopathy is a personality disorder that afflicts less than one percent of the general population. However, among adult offenders, psychopathy afflicts approximately 10 to 25 percent of adult offenders .
Monosodium glutamate, or MSG, is a powerful flavor enhancer. The flavor produced by MSG is termed “umami,” a Japanese expression roughly translating to “tastiness.” As a flavor enhancer, MSG increases the total taste of food, boosts certain flavor characteristics in meat and poultry such as saltiness, and emits no secondary aroma.
There is hardly anything under the sea as simultaneously simple and confusing as the hagfish. The pink, tubular fish has four hearts but no eyes, stomach or taste buds. Hagfish are one of the jawless fishes that comprise the superclass Cyclostomata.
“I’ve never had a day that I don’t want to go to work. I’m so lucky to get to learn something new every single day.” - Jeremy Day, the Principal Investigator of the Day Lab, a neurobiology lab located in Birmingham, Alabama.

Dr. Amanda Freise is a professor and lecturer at the University of California, Los Angeles Department of Microbiology, Immunology, and Molecular Genetics (MIMG). She and her students are involved in the Science Education Alliance-Phage Hunters Advancing Genomics and Evolutionary Science (SEA-PHAGES) national virology research program, which enables undergraduates nationwide to conduct studies on newly-discovered viruses.
The Nobel Prize in Medicine and Physiology for 2018 was awarded to Dr. James P. Allison and Dr. Tasuku Honjo for making breakthrough discoveries on strategies for treating cancer by preventing the “ignorance” of tumors by the immune system. Developing cancer cells are normally detected by surveying white blood cells, or T-lymphocytes, that recognize the tumor progenitors as abnormal and target the abnormal cells for destruction. However, as a tumor develops, the cancer cells of the tumor begin to send inhibitory signals to immune cells, causing them to “ignore” the growing tumor until it is virtually invisible to the immune system.
