Science is the body of knowledge, as well as the process of pursuing that knowledge, about the universe we observe. Using scientific knowledge, we can infer the past and predict the future, with certain confidence.
The gulf toadfish, Opsanus beta, is a marine teleost fish that was found along the coast of Florida and in the Gulf of Mexico. “The toadfish is an excellent model to study the interactions between 5-HT, its receptors and transporters and the stress hormone, cortisol, as toadfish have a unique physiological process, pulsatile urea excretion that involves all these components. 5-HT is a neurochemical that has been intensely studied in mammals for some time. It is most commonly known for its role in depression, however, it has many critical functions within the body and disruptions have negative consequences: drug addiction, behavioral disorders (in addition to depression; stress, anxiety, aggression, violence) and physiological problems (cardiovascular disease, irritable bowel syndrome, obesity, migraines, nausea)."
The guest speaker of IF club Danielle McDonald’s lab is trying to establish a greater understanding of the role of serotonin (5-HT; 5-hydroxytryptamine) within teleost fish by investigating the receptors that mediate its response and the transporters that facilitate its movement.
The key to becoming a sand collector is the ability to observe and wonder. One must learn how to look closely at not only sand but of the surrounding area in which one is collecting. Whether a beach, lake, river, desert, etc., the surrounding area will tell you much about the sand beneath your feet and how it got there.
One of the myths about sand collecting is that once you have collected a sample from a given area, there is no need to look further as all sand will be exactly the same – not true. Often one will discover that sand can be quite different sample to sample within just a few yards or even feet of each other, so it is very important to observe and wonder.
The guest speaker of IF club Matthew Phillips had collected sand samples in Keys.
The guest speaker of IF club Dr. Gai’s research aims to understand how the brain processes sound information and how we may improve designs of hearing aids and cochlear implants to help people with hearing impairments and communication disorders. At the behavioral level, she assesses humans’ and animals’ ability to perceive and separate sound sources from interfering backgrounds. At the physiological level, she examines how single neurons interact with external input and networks.
Dr.Wilson is one of the guest speakers in IF club. Her research lab focuses on characterizing the mechanisms that metabolically and developmentally integrate hosts and symbionts. Day's Edge Productions announce the production of their NSF funded films about symbiosis and their group’s work with aphid amino acid transporters!
SYMBIOSIS is a series of short films exploring the amazing science of symbiosis, a mutually beneficial relationship between two or more species. In Episode 4, “From Pests to People,” learn why biologists are so interested in understanding symbiosis, discover what the humble pea aphid can teach us about how life works on our planet, and find out what it takes to be a scientist!

The guest speaker of IF club Dr.Blomberg's research focuses on the immune system and deficits that occur with age as well as the effects of CBSM (cognitive behavioral stress management) and relaxation therapy (RT) intervention in breast cancer patients on their immune system and inflammation. She is currently investigating the molecular and cellular pathways contributing to better conditions for immune response and survival in cancer patients.
Dr. Sheyum Syed is one of guest speakers in IF club. He conducted researchs on circadian rhythms. For instance, The laboratory utilizes time-lapse fluorescence imaging to detect molecular kinetics in individual fruitfly cells and combines infra-red and video tracking technologies to capture dynamics of behaving flies.
