        <Desc>Cultivate:Cultivate programs introduce and re-orient students and adults through hands-on, industry-informed curriculum and workforce training. FirstHand STEM Education:FirstHand offers free year-round, project-based learning in partnership with local schools and community organizations, designed to provide skills-based career exposure. The FirstHand Lab is a connector for students from surrounding neighborhoods to the thriving entrepreneurial and innovation system in Greater Philadelphia and provides a real-world lab experience.Since the beginning of the program, in 2014, over 2,360 students in the surrounding West Philadelphia community gained a better appreciation for science, at the middle school level, and at the high school level discovered and began to consider the various career tracks in STEM or STEM-adjacent roles, as they prepare for a post-secondary education and/or career. Workforce Development: The Science Center's Workforce Development program seeks to connect Philadelphia residents to jobs at biotech companies in University City and beyond. The Science Center is committed to developing a strategic workforce development model that fits the needs of companies, strengthens the STEM talent pipeline, and benefits the community around us.In the first cohort in 2020, 22 participants without a traditional four year-college degree received STEM training. Mentors from local biotech companies engaged participants in at-home lab experiments using custom STEM kits.</Desc>

        <ExplanationTxt>The Science Center is a tax-exempt organization under Section 501(c)(3) of the Internal Revenue Code, although its consolidated entities, the Park, PTI, PIV, and SCEC, are for profit entities which are subject to income taxes. Total federal and state income tax expense from the consolidated entities was $-0- and $1,400,000 for the years ended December 31, 2020 and 2019, respectively. U.S. GAAP requires management to evaluate tax positions taken and recognize a tax liability, if the Center has taken an uncertain tax position that more likely than not would not be sustained upon examination by a government authority. Management has analyzed the tax positions taken by the Center, and has concluded that as of December 31, 2020 or 2019, there are no uncertain positions taken or expected to be taken that would require recognition of a liability or disclosure in the consolidated financial statements. The Center would recognize future accrued interest and penalties related to unrecognized tax benefits and liabilities in income tax expense if such interest and penalties are incurred. There were no income tax related interest and penalties recorded for each of the years ended December 31, 2020 or 2019.</ExplanationTxt>

        <ExplanationTxt>Urban Research Park: In 1963 the Science Center was built on the foundation of real estate at a time when labs and research facilities were needed for cross disciplinary and cross-institutional collaborations. Our focus on providing researchers and entrepreneurs with the resources to advance the commercialization of their technologies hasn't changed over the last 60 years. The way we serve them has evolved with the changing needs of the ecosystem and now includes an integrated combination of physical space and programs to advance science and technology innovation. Today, the campus-like complex consists of six buildings spanning 888,000 square feet of office and laboratory space. These buildings are part of the larger uCity Square campus developed in partnership with Wexford Science + Technology and Ventas, Inc. uCity Square consists of 27 acres, 17 buildings, 200 companies and over 10,000 people.</ExplanationTxt>

        <ExplanationTxt>Commercialization: Science Center commercialization activities are designed to offer startups the right help at the right time to accelerate and scale healthcare and tech businesses. In 2020, the Science Center supported 94 startups and invested $600,000. Those startups went on to raise over $43 million in follow-on funds and create over 60 jobs. 45% of the startups were minority founded, 55% had a foreign-born founder, and 33% were led by female founders. QED Proof-of-Concept Program: The QED Program solicits life science R&amp;D project proposals from leading research centers across PA, NJ, and DE. The key goal of the program is to retire the business risk in these early-stage projects, increasing their attractiveness to follow-on investment by life science companies and private investors. In 2020, the Science Center supported 15 projects through the QED program with three projects receiving a total of $600,000 in funding which is provided equally from the Science Center and the finalist's host institution. Since its inception in 2009, the QED program has provided development services for over 150 academic researchers with over $8 million invested in 44 projects. Fourteen startups or licensing deals have resulted. ic@3401: ic@3401 is a vetted community of startups, experts, investors, and resources designed to help early-stage businesses scale. Located at the intersection of academic, business and civic interests and serving as the hub for all Science Center commercialization activity, ic@3401 helps tech and tech-enables startups pilot prototypes, get first revenue, establish corporate partnerships, hire talent, and raise capital. Since 2016 more than 70 ic@3401 member companies have raised over $80 million. ic@3401 boasted 72 members companies in 2020. Thirty-one of those companies raised more than $22 million, and launched 16 new products. Launch Lane Accelerator: The Launch Lane Accelerator (fka Digital Health Accelerator) supports tech-enable startups with a prototype and ready to transition to sales. Launch Lane utilizes an anonymous application method designed to debias the selection process that has resulted in over 50% of participants being women or minority founded. Launch Lane participants receive funding, mentorship, introductions, and workspace at ic@3401. In 2020, the Science Center ran a Launch Lane cohort, investing $300,000 in seven startups. Those companies went on to raise close to $2 million in follow-on funding. A total of 35 companies have gone through the Launch Lane accelerator since 2015, generating $50 million in revenue, raising over $300 million in follow-on funding and creating 300 jobs. Global Soft Landing: Our Global Soft Landing Program enable companies to form meaningful relationships with stakeholders and establish a presence in domestic and international life sciences and technology markets. In 2020, 21 companies representing nine countries participated in four Global Soft Landing bootcamps. Sourcing Innovation: The Science Center connects industry and government to researchers through a mechanism that channels research partnership funds in exchange for an opportunity to license or partner with the researchers behind high-value technologies. Examples include the Science Center's participation in the DRIVe Accelerator Network, an initiative of the US Department of Health and Human Services' Biomedical Advanced Research and Development Authority (BARDA) that seeks to identify the most innovative products and technologies to protect Americans from the most serious systemic, natural and intentional health security threats.</ExplanationTxt>
