Bioscience Discoveries That Will Blow Your Mind (updated)

Jack Andraka, 16-year-old inventor and 2012 Intel Science Fair Grand Prize winner, developed a diagnostic sensor for pancreatic, ovarian, and lung cancer.

• The sensor costs $0.03 to produce, takes five minutes to run, and claims 100% accuracy in detecting cancer at the earliest stage (when survival rates are near 100%).
• The technology relies on the protein mesothelin, which is found in high levels in the blood during the early stages of these specific cancers.
• Detection utilizes single-walled carbon nanotubes woven with antibodies to change electrical properties upon binding to the target protein.
• The device is 168 times faster, over 26,000 times less expensive, and over 400 times more sensitive than the current standard ($800) diagnostic technique.
• Andraka's inspiration stemmed from a family friend's death from pancreatic cancer at age 13; 85% of cases are currently diagnosed too late, with survival rates below 2%.
• The platform is adaptable to detect other diseases (HIV, Alzheimer's, heart disease) by simply swapping the specific antibodies used in the sensor.
• Andraka initially cultivated E. coli on his kitchen counter and later secured lab space after contacting 200 researchers, receiving 199 rejections before finding mentorship at Johns Hopkins.

Tejal Desai, Professor of Bioengineering and Therapeutic Science at UCSF, focuses on nanotechnology to improve drug delivery.

• She is developing a therapeutic film smaller than a contact lens that releases medication at the retina over 6–12 months, eliminating the need for monthly eye injections used for macular degeneration.
• Her team is engineering materials to transiently open tight junctions between cells, enabling the delivery of protein-based drugs (like insulin) via non-invasive oral routes; currently, less than 0.01% of oral drugs enter the bloodstream.
• Desai advocates for improved STEM education for girls, noting that while interest is equal in younger ages, women feel forced to make trade-offs between science careers and other life goals at higher levels.
• She emphasizes that science education should be made exciting and accessible early to prevent the attrition of female talent in STEM fields.

Dr. David Baltimore, 1975 Nobel Laureate and President Emeritus of Caltech, discusses the maturation of gene therapy.

• His current translational research focuses on using genes and viruses to enhance the immune system's ability to fight HIV and cancer.
• Four specific programs include: delivering genes for antibodies to prevent HIV infection; knocking out surface proteins on HIV-host cells using small interfering RNAs; using genes to create more effective vaccinations; and programming killer T-cells to attack cancer.
• Baltimore highlights that HIV and cancer evade the immune system because they mutate and vary their genetic constitution faster than the immune system can recognize.
• He notes that the first gene therapy was approved in Europe last year, with more in experimental use, but emphasizes the critical need for NIH funding to sustain this progress.

Dr. Francis Collins, Director of the National Institutes of Health (NIH), outlined two major themes of current biomedical breakthroughs.

• Genomics: The cost of sequencing a human genome has dropped from roughly $400 million in 2001 to under $7,000 today, with portable devices capable of sequencing a genome in three days.
• While 7,000 diseases now have a known molecular basis, treatments exist for only about 250, creating an urgent need for translational research to bridge the gap.
• The Cancer Genome Atlas has sequenced approximately 20,000 tumors (80,000 genomes total) to identify specific mutations, moving treatment away from "one-size-fits-all" chemotherapy toward precision medicine.
• Collins cited a Stage 4 lung cancer patient who achieved three years of remission after treatment with crizotinib, a drug targeting a specific ALK kinase rearrangement in her tumor.
• The Brain Initiative: A new 10–15 year effort announced by the President aims to map brain circuits to treat epilepsy, Alzheimer's, Parkinson's, and schizophrenia.
• Recent advances include "Brainbow" (color-coding neurons), 3D transparent brain imaging, and brain-computer interfaces allowing quadriplegics to control robotic arms via thought.

Eidolon (referred to as "Eidolon" in transcript, likely Prof. Ali Khademhosseini or similar bio-engineering expert based on context of cell phone microscopes), discusses the convergence of computing power and mobile devices.

• Cell phone cameras are following Moore's Law, reaching over 40 megapixels, enabling the conversion of phones into microscopes capable of imaging viruses and cells.
• He proposes a "micro-internet" where 6.5 billion devices collect diagnostic data to monitor disease evolution and epidemiology on a massive scale.
• New devices use computational imaging rather than physical lenses to remain compact and cost-effective for field use in developing nations.
• Potential applications include detecting E. coli, identifying allergens (peanuts), and performing blood analysis (counting red/white blood cells) directly on smartphones.

Panel Consensus on Resources and Funding:

• Despite scientific optimism, the panel noted a 20% reduction in the purchasing power of biomedical research funding over the last decade, exacerbated by recent sequestration measures.
• Dr. Baltimore and Dr. Collins expressed concern that young scientists face a constrained environment, lacking the clear national support and funding certainty that characterized earlier eras (e.g., the Sputnik era).
• To address funding gaps and encourage innovation, NIH has introduced high-risk, high-reward grant mechanisms like the "Director's New Innovator Award" and "Pioneer Awards."
• Panelists emphasized the need to protect young investigators with bold, untested ideas who lack the credibility or preliminary data of senior researchers.

Educational and Cultural Themes:

• Speakers highlighted the importance of early exposure to science, citing specific influences: Andraka's parents asking questions rather than answering them; Desai's geologist-turned-physicist teacher taking AP Physics outdoors; Baltimore's mother enrolling him in a Jackson Lab program; and Collins' high school chemistry teacher using a "mystery box" to teach scientific inquiry.
• The panel argued that youth should be viewed as a solution rather than a problem, capable of leveraging open-access information (Google, Wikipedia) to innovate regardless of age or gender.
• Jack Andraka urged the audience to stop passive consumption of social media (e.g., Instagram) and actively engage in invention, noting that the internet will double the number of innovators in the coming years as 3.5 billion more people come online.
