An infectious disease specialist at Hackensack University Medical Center in New Jersey, Dr. Bindu Balani treated the state's first confirmed COVID-19 patient in March 2020. In this episode, Bindu shares her experiences on the front line of the battle to identify, treat, and stem the subsequent surge of COVID-19 cases. From this unique vantage point, we learn how all units of the hospital mobilized and adapted to protect and serve the patients in their care. A new virtual interview series from LabXchange at Harvard University, the Xchange showcases the diverse roles, projects, and initiatives that make up the intersecting fields of science, education, and health. Hosted by LabXchange Faculty Director Robert Lue, our first season features a range of perspectives on the impact of COVID-19.

A BioBlitz is a way for our community to work together to find as many species as possible in Ohio during the four days of the Science Festival. You can participate by simply snapping photos of plants and animals in the wild and uploading them to the free app iNaturalist. Observations will be made available to naturalists and researchers. Let\'s explore Ohio\'s biodiversity!

What are the characteristics that define populations? What causes populations to grow or decline? In the following video you will learn how a population is a group of individuals of the same species living within a designated area at one time. Three important structural aspects of a population are: dispersion pattern, population density and growth rate. [14:24]

Static electricity is an electric charge on the surface of an object. When the difference between the charge on the object and the charge on a nearby object becomes great enough, a spark of electric current leaps between them. Learn about static electricity and watch the sparks produced by a Van de Graaff generator. Find out how lightning is created. See how static charges attract and repel. [10:58]

Students act as if they are biological engineers following the steps of the engineering design process to design and create protein models to replace the defective proteins in a child’s body. Jumping off from a basic understanding of DNA and its transcription and translation processes, students learn about the many different proteins types and what happens if protein mutations occur. Then they focus on structural, transport and defense proteins during three challenges posed by the R&D; bio-engineering hypothetical scenario. Using common classroom supplies such as paper, tape and craft sticks, student pairs design, sketch, build, test and improve their own protein models to meet specific functional requirements: to strengthen bones (collagen), to capture oxygen molecules (hemoglobin) and to capture bacteria (antibody). By designing and testing physical models to accomplish certain functional requirements, students come to understand the relationship between protein structure and function. They graph and analyze the class data, then share and compare results across all teams to determine which models were the most successful. Includes a quiz, three worksheets and a reference sheet.

Once the structure of DNA was discovered, the next challenge was determining how the sequence of letters coded for the 20 amino acids could make protein. In theory, one or two letters can only code for 4 or 16 amino acids, respectively. A scheme using three letters, a triplet code, is the minimum necessary to encode for all the amino acids. [1:08]

View this video/animation to see how one type of immune cell-the helper T cell-interprets a message presented at the surface of the cell membrane. The message is an antigen, a protein fragment taken from an invading microbe. A series of events unfolds that results in the production of many clones of the helper T cell. These identical T cells can serve as a brigade forming an essential communication network to activate B cells, which make antibodies that will specifically attack the activating antigen. [4.21]
