adolescent: Someone in that transitional stage of physical and psychological development that begins at the onset of puberty, typically between the ages of 11 and 13, and ends with adulthood.
anxiety: A nervous reaction to events causing excessive uneasiness and apprehension. People with anxiety may even develop panic attacks.
brain scan: A technique to view structures inside the brain, typically with X-rays or a magnetic resonance imaging (or MRI) machine. With MRI technology — especially the type known as functional MRI (or fMRI) — the activity of different brain regions can be viewed during an event, such as viewing pictures, computing sums or listening to music.
cisgender: Someone whose gender identity matches that of the sex they were assigned at birth. (The Latin prefix cis- means “on the same side.”)
data: Facts and/or statistics collected together for analysis but not necessarily organized in a way that gives them meaning. For digital information (the type stored by computers), those data typically are numbers stored in a binary code, portrayed as strings of zeros and ones.
data processing: Putting data into a computer and having the computer store, organize or change it with the aim or extracting useful information from those data.
depression: (in medicine) A mental illness characterized by persistent sadness and apathy. Although these feelings can be triggered by events, such as the death of a loved one or the move to a new city, that isn’t typically considered an “illness” — unless the symptoms are prolonged and harm an individual’s ability to perform normal daily tasks (such as working, sleeping or interacting with others). People suffering from depression often feel they lack the energy needed to get anything done. They may have difficulty concentrating on things or showing an interest in normal events. Many times, these feelings seem to be triggered by nothing; they can appear out of nowhere.
development: (in biology) The growth of an organism from conception through adulthood, often undergoing changes in chemistry, size and sometimes even shape.
gender: The complex relationship between someone’s body, their identity and often how their culture tries to assign them roles and behaviors. Gender and biological sex are often incorrectly used to mean the same thing. Gender identity includes binary (female or male) and nonbinary (genderfluid, genderqueer and more). People share some of their gender identity by their choice of pronouns; for example, he, she or they are common ones. Someone’s gender can be the same or different from the sex that individual was assigned at birth.
gender identity: A term for someone’s strong internal sense of being male, female, both, neither or somewhere in between. While a person’s gender identity commonly matches the sex they were assigned at birth, this isn’t always the case.
hormone: (in zoology and medicine) A chemical produced in a gland and then carried in the bloodstream to another part of the body. Hormones control many important body activities, such as growth. Hormones act by triggering or regulating chemical reactions in the body.
link: A connection between two people or things.
mechanism: The steps or process by which something happens or “works.” It may be the spring that pops something from one hole into another. It could be the squeezing of the heart muscle that pumps blood throughout the body. It could be the friction (with the road and air) that slows down the speed of a coasting car. Researchers often look for the mechanism behind actions and reactions to understand how something functions.
mental health: A term for someone’s emotional, psychological and social well-being. It refers to how people behave on their own and how they interact with others. It includes how people make choices, handle stress and manage fear or anxiety. Poor mental health can be triggered by disease or might reflect a short-term response to life’s challenges. It can occur in people of any age, from babies to the elderly.
middle school: A designation for grades six through eight in the U.S. educational system. It comes immediately prior to high school. Some school systems break their age groups slightly different, including sixth grade as part of elementary school and then referring to grades seven and eight as “junior” high school.
puberty: A developmental period in humans and other primates when the body undergoes hormonal changes that will result in the maturation of reproductive organs.
risk: The chance or mathematical likelihood that some bad thing might happen. For instance, exposure to radiation poses a risk of cancer. Or the hazard — or peril — itself. (For instance: Among cancer risks that the people faced were radiation and drinking water tainted with arsenic.)
Science Talent Search: An annual competition created and run by Society for Science. Begun in 1942, this event brings 40 research-oriented high school seniors to Washington, D.C. each year to showcase their research to the public and to compete for awards. Since spring 2016, this competition has been sponsored by Regeneron Pharmaceuticals.
survey: (with people) To ask questions that glean data on the opinions, practices (such as dining or sleeping habits), knowledge or skills of a broad range of people. Researchers select the number and types of people questioned in hopes that the answers these individuals give will be representative of others who are their age, belong to the same ethnic group or live in the same region. (n.) The list of questions that will be offered to glean those data.
therapy: (adj. therapeutic) Treatment intended to relieve or heal a disorder.
transgender: An adjective for someone whose gender does not match the sex they were assigned at birth. Sex is usually assigned at birth based on someone’s genitalia.
unique: Something that is unlike anything else; the only one of its kind.
