Summer Research Internships Prepare High School Students for 21st Century Biomedical Careers.

STEM internships for both high school and college students provide early opportunities for students to discover careers of interest and career paths they may not otherwise experience. For over 25 years, the University of Alabama at Birmingham's (UAB) Center for Community OutReach Development (CORD) has provided rising high school seniors with opportunities to conduct research in federally-funded laboratories under the mentorship of UAB faculty. This paper evaluates CORD's High School Summer Science Institute III Program (SSI III) and its impact on participants' STEM career trajectories. Outcomes were tracked for SSI III participants over an eight-year period, and former interns' perceptions of the program reported. Over 99% of surveyed interns (N=102) chose a STEM undergraduate major, and 97% of the former interns reported they were pursuing STEM careers. Nearly all interns indicated their SSI-III experience was very positive and influenced their career decision. Over half of the interns matriculated into an undergraduate STEM major at UAB, providing the university with return as more excellent students for their investment in the program. These results highlight the importance of high school student involvement in STEM internships as a pathway that leads towards STEM careers.

Creating a Sustainable Partnership Between a Science Center, University, and Local School Districts: A Retrospective on Over 20 Years of Successful Programming and Partnership.

The University of Alabama at Birmingham (UAB) and the McWane Science Center have partnered for over 20 years to provide secondary students in Alabama opportunities to conduct inquiry-based, standards-aligned science labs. LabWorks (middle school) and GENEius (high school) programs offer multiple research laboratory experiences in which students explore molecular biology, physical science, genetics, engineering, anatomy, and forensic science, with associated summer professional development for teachers: BioTeach and GeoTeach. These programs each attract 3,000-4,000 participants annually. This partnership has been synergistic, allowing the science center to offer high-level secondary science programming, while giving the university a conduit into the K-12 world. Originally, these programs were developed through Howard Hughes Medical Institute funding, and then expanded through support from the National Institutes of Health, the National Science Foundation, and the US Department of Education. These programs have excited secondary students and teachers about science education and careers, provided authentic science experiences, and given teachers the opportunity to experience a model of learning that engages students in "real science" closely linked to their curriculum. For over 20 years, this unique, evolving partnership has increased the understanding of over 90,000 students and teachers relative to the opportunities that science and STEM careers hold.

"Sickle cell anemia: tracking down a mutation": an interactive learning laboratory that communicates basic principles of genetics and cellular biology.

"Sickle cell anemia: tracking down a mutation" is a full-day, inquiry-based, biology experience for high school students enrolled in genetics or advanced biology courses. In the experience, students use restriction endonuclease digestion, cellulose acetate gel electrophoresis, and microscopy to discover which of three putative patients have the sickle cell genotype/phenotype using DNA and blood samples from wild-type and transgenic mice that carry a sickle cell mutation. The inquiry-based, problem-solving approach facilitates the students' understanding of the basic concepts of genetics and cellular and molecular biology and provides experience with contemporary tools of biotechnology. It also leads to students' appreciation of the causes and consequences of this genetic disease, which is relatively common in individuals of African descent, and increases their understanding of the first principles of genetics. This protocol provides optimal learning when led by well-trained facilitators (including the classroom teacher) and carried out in small groups (6:1 student-to-teacher ratio). This high-quality experience can be offered to a large number of students at a relatively low cost, and it is especially effective in collaboration with a local science museum and/or university. Over the past 15 yr, >12,000 students have completed this inquiry-based learning experience and demonstrated a consistent, substantial increase in their understanding of the disease and genetics in general.

Combined DNA, toxicological and heavy metal analyses provides an auditing toolkit to improve pharmacovigilance of traditional Chinese medicine (TCM).

Globally, there has been an increase in the use of herbal remedies including traditional Chinese medicine (TCM). There is a perception that products are natural, safe and effectively regulated, however, regulatory agencies are hampered by a lack of a toolkit to audit ingredient lists, adulterants and constituent active compounds. Here, for the first time, a multidisciplinary approach to assessing the molecular content of 26 TCMs is described. Next generation DNA sequencing is combined with toxicological and heavy metal screening by separation techniques and mass spectrometry (MS) to provide a comprehensive audit. Genetic analysis revealed that 50% of samples contained DNA of undeclared plant or animal taxa, including an endangered species of Panthera (snow leopard). In 50% of the TCMs, an undeclared pharmaceutical agent was detected including warfarin, dexamethasone, diclofenac, cyproheptadine and paracetamol. Mass spectrometry revealed heavy metals including arsenic, lead and cadmium, one with a level of arsenic >10 times the acceptable limit. The study showed 92% of the TCMs examined were found to have some form of contamination and/or substitution. This study demonstrates that a combination of molecular methodologies can provide an effective means by which to audit complementary and alternative medicines.
