Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.

◐Partially SupportedNew technologies like cell phones and MRIs initially carry unknown risks, with some negative consequences identified later.

◐Partially SupportedThe 2001 Human Genome Project declaration of victory was based on a rough draft of 92% of the genome, and it was haploid, not representing the diploid nature of most humans.

◐Partially SupportedGermline manipulation in pigs for organ transplants could contribute to acceptance of germline editing in humans if safe.

◐Partially SupportedThe 'damage school' of aging proposes fixing damage, while the 'epigenetics school' suggests convincing cells they are young will lead to self-repair.

◐Partially SupportedModifying CCR5 to confer HIV resistance might increase sensitivity to West Nile virus or certain influenza strains.

◐Partially SupportedThe goal of developing enhanced cell and organ therapies is to create treatments that are immunologically superior, less rejected, and resistant to pathogens, senescence, and damage.

◐Partially SupportedProteins like CCR5 can be engineered to retain immunological function while blocking viral binding, potentially conferring resistance to viruses like HIV.

◐Partially SupportedMethods predating CRISPR, such as SSAPs and homologous recombination, are precise and powerful for genome editing, with SSAPs enabling the creation of billions of edited cells daily by a single person.

◐Partially SupportedAging may be a negotiable biological program that can be intervened upon to alter lifespan.

◐Partially SupportedEpigenetically reprogramming cells to become pluripotent stem cells can increase embryo availability for IVF without affecting the germline.

◐Partially SupportedAging increases risk for infectious diseases, cognitive consequences, and accidental death, with steep increases around age 60.

◐Partially SupportedInterventions targeting the core systems biology of aging could potentially alter the biological clock leading to rejuvenation.

◐Partially SupportedEffective gene therapy can potentially offer a one-and-done treatment for diseases.

◐Partially SupportedSynthesizing whole genomes is advantageous when numerous genes need to be altered.

◐Partially SupportedMolecular 'flight recorders' can be engineered into cells to report on physiological states and allow for millions of edits.

◐Partially SupportedDogs receive better medical care than humans, as evidenced by the continuous use of a Lyme disease vaccine in dogs while it was withdrawn for humans.

◐Partially SupportedThe Salvador Dali technique of using a falling spoon to induce creative inspiration upon waking is likely effective for many.

◐Partially SupportedGeorge Church eats right before bed, which is contrary to general advice.

◐Partially SupportedDisclosing diseases like narcolepsy and diabetes can be life-saving.

◐Partially SupportedHomologous recombination is a precise editing method effective over large distances, unlike CRISPR which tends to be imprecise and limited in scope.

◐Partially SupportedCRISPR can be used to eliminate endogenous retroviruses from the germline of animals, such as pigs.

◐Partially SupportedCRISPR can be used to eliminate mammalian viruses from the environment, as demonstrated against African swine fever virus.

◐Partially SupportedPrimate trials show survival of around 600 days for gene-edited pig organ transplants.

◐Partially SupportedA Lyme disease vaccine was withdrawn from the market due to false claims linking vaccines to autism.

◐Partially SupportedDelivering genes to a subset of cells can lead to those cells delivering proteins more broadly, potentially affecting the whole body.
