Biotech & Genomics
Biotechnology is quietly reshaping healthcare in ways that will affect every family. Gene editing therapies are FDA-approved. Your doctor can sequence your tumor’s DNA to pick the right drug. AI is compressing drug discovery timelines from decades to years. Here’s what you need to know.
Gene Editing (CRISPR) — What It Is
Section titled “Gene Editing (CRISPR) — What It Is”CRISPR is a tool that lets scientists find a specific spot in your DNA and change it — like a molecular find-and-replace.
The first CRISPR therapy, Casgevy, was FDA-approved in late 2023 for sickle cell disease and beta-thalassemia. In 2025, researchers at the University of Pennsylvania created a one-off, personalized CRISPR treatment for an infant named KJ Muldoon, correcting a rare liver mutation — the first time a custom gene edit was designed for a single patient.
As of early 2026, over 20 CRISPR therapies are in Phase II trials for cancers and heart disease. Long-term effects remain unknown.
Personalized Medicine
Section titled “Personalized Medicine”Instead of one-size-fits-all prescriptions, doctors can now sequence your genome and pick treatments matched to your genetic profile. This is already standard in cancer care — tumor DNA is routinely sequenced to select targeted drugs.
NIH data shows lung cancer patients receiving genomically matched therapy had median survival of 28.7 months versus 6.6 months without it.
The gap: genomic databases still skew heavily toward European-descent populations, which can worsen health disparities for underrepresented groups.
Direct-to-Consumer Genetic Testing — A Warning
Section titled “Direct-to-Consumer Genetic Testing — A Warning”Tests like 23andMe reveal ancestry, disease risk markers, and how your body metabolizes drugs. But there’s a cautionary tale.
23andMe filed for bankruptcy in March 2025 and sold 15+ million customers’ genetic data to TTAM Research Institute. A 2023 breach had already exposed 7 million users’ data. Unlike medical records, consumer DNA data is not protected by HIPAA. Twenty-seven states sued over the data transfer.
Key takeaway: Once you hand over your DNA, you have limited control over where it ends up.
AI + Biotech
Section titled “AI + Biotech”AI is compressing drug discovery timelines that historically took 10-15 years.
- Machine learning models now predict protein structures, screen millions of virtual drug candidates, and design novel antibodies
- In 2025, an AI-designed drug (a TNIK inhibitor for pulmonary fibrosis) reached a Phase 2a clinical trial — one of the first AI-originated molecules to reach humans
- AI-related biotech publications surged from near-zero in 2015 to 275 in drug discovery alone by 2024
Honest caveat: experts remain divided on whether AI-designed drugs can truly outperform traditional methods yet. The pipeline is accelerating, but proof is still early.
Longevity Science — Real vs. Hype
Section titled “Longevity Science — Real vs. Hype”GLP-1 drugs (Ozempic, Mounjaro): Real and expanding. Beyond weight loss and diabetes, clinical data shows cardiovascular benefits and reduced all-cause mortality. Trials are underway for Alzheimer’s, addiction, and kidney disease. Nature Biotechnology asks: “Are GLP-1s the first longevity drugs?”
Senolytics (drugs that clear damaged “zombie” cells): Promising but early. The dasatinib + quercetin combination shows results in animal models and early human studies. No FDA-approved senolytic therapy exists yet.
Rapamycin, metformin: Being studied for anti-aging properties, but evidence in healthy humans is preliminary.
Ethical Questions Worth Thinking About
Section titled “Ethical Questions Worth Thinking About”- Access: Gene therapies cost $1-2 million per treatment. Who gets them?
- Germline editing: Changes to embryos pass to all future generations. Most scientists say this line should not be crossed for non-medical enhancement.
- Genetic privacy: No comprehensive U.S. federal law protects consumer genetic data.
- Enhancement vs. treatment: When does fixing a disease become “designing” a person?
