• Personalized cancer vaccines are at the frontier: mRNA platforms (e.g., autogene cevumeran & BNT116) sequence each tumor to generate a bespoke vaccine and pair it with checkpoint inhibitors. Early trials for pancreatic and lung cancer report potent immune responses and reduced recurrence risk .

• Senescent‑cell clearance may combat aging. The dasatinib–quercetin cocktail reduces senescence and inflammatory markers in COPD models , and a STAMINA pilot trial improved cognition in older adults at risk for Alzheimer’s disease while lowering TNF‑α with minimal side effects . Targeted senolysis hints at tangible health‑span gains.

• Cellular rejuvenation is evolving. A single rejuvenation gene (SB000) reverses multiple epigenetic clocks and senescence markers while preserving cell identity, outperforming Yamanaka factors, whose continuous expression can cause tumors. Safer transient reprogramming could reset our cells’ biological age.

• Gene‑therapy partial reprogramming: An inducible OSK gene therapy delivered via AAV to very old mice doubled their remaining lifespan (109%) and improved frailty scores while reversing epigenetic age in mouse tissues and human keratinocytes . Genetic rejuvenation is edging from proof‑of‑concept toward translation.

• Metabolic reprogramming taps into sirtuins and NAD⁺/AMPK pathways. Caloric restriction raises the NAD⁺/NADH ratio and activates AMPK, boosting sirtuin activity, reducing ROS and enhancing autophagy and DNA repair . These pathways offer dietary and pharmacologic levers to counter age‑related decline.

• NAD⁺ boosters like NMN are moving into humans. A 60‑day trial in middle‑aged adults showed NMN raised blood NAD levels dose‑dependently, improved six‑minute walk distance and SF‑36 health scores, and maintained blood biological age; doses up to 900 mg/day were safe . Supporting our cellular energy currency may sustain vitality.

• Metformin’s next act: The TAME trial will enroll roughly 3,000 adults aged 65‑79 at 14 U.S. sites to test whether metformin delays heart disease, cancer and dementia . A positive outcome could convince regulators that aging itself can be treated with safe, inexpensive drugs.

• Gut microbiome tuning emerges as a longevity lever. Evidence from model organisms shows microbes can shape host aging, and long‑lived people have diverse, beneficial gut flora and enhanced gut homeostasis . Diets rich in fiber, regular exercise and pro/pre/postbiotic supplements may support gut‑brain and gut‑muscle axes for healthy aging

• Brain‑computer interfaces (BCIs) are restoring voices. A UC Davis device implanted microelectrode arrays in an ALS patient’s speech region, translating neural signals into text and a synthetic voice matching his pre‑ALS voice. After 30 minutes of training it achieved 99.6% accuracy on a 50‑word set; after 1.4 hours, it decoded a 125,000‑word vocabulary with 97.5% accuracy . He used it for 248 hours over 32 weeks to converse with loved ones

• Streaming brain‑to‑voice neuroprostheses bring natural conversation closer. In 2025, researchers implanted electrodes in a woman paralyzed for 18 years and used deep learning to translate her intended speech into audible words at 47.5 words/min for a full vocabulary and 90.9 words/min for a 50‑word set. The system achieved >99% success, near‑real‑time (≈0.08 s) latency and reproduced her voice
