I was fishing and thought about aptamers….

love this book… and the first time I learned science can be good and dangerous

A room-temperature RNA test could dramatically simplify diagnostics. 🧬⚡ Researchers built a CRISPR/Cas13a system that detects RNA without PCR, amplification, or temperature control. It works at ambient conditions, delivers results in under an hour, and reaches femtomolar sensitivity—on par with lab-grade assays. Because it’s easily reprogrammable, the same platform can be adapted to spot new viruses, bacterial genes, or disease biomarkers, making it ideal for clinics, field testing, and low-resource settings.

A new frontier in RNA-based cancer therapy is taking shape. 🧬🎯 Researchers have designed a virus-inspired biotechnical vector (VIBV) that tackles one of gene therapy’s hardest problems: safe, efficient delivery. It mimics viruses for high uptake, but uses biocompatible nanomaterials to reduce immune risk. What makes it powerful is programmability. One vector can deliver multiple RNA therapies in sequence: • miRNA sponges that neutralize cancer-promoting RNAs like miR-21 and miR-155 • shRNAs that silence oncogenes such as MYC and VEGF • additional RNA cargos that boost immune attack and slow tumor growth Still preclinical, but the vision is big: a single platform combining gene silencing, immunotherapy, and tumor control with higher precision and lower toxicity.

A living tumor-on-a-chip just revealed how cancers block immune attacks. 🧬🛑 UPenn researchers built a human lung cancer chip that recreates blood vessels and immune barriers, letting them watch CAR T cells interact with tumors in real time. They found tumor vessels send brief “help signals” to attract CAR T cells — but the signals fade fast. Adding vildagliptin, a diabetes drug that prevents signal breakdown, restored communication and allowed CAR T cells to infiltrate and attack the tumor. This explains why solid tumors resist immunotherapy — and offers a human-relevant way to design better CAR T treatments without animal models.

Scientists just found a way to dismantle cancer’s RNA-built growth hubs. 🧬💥 Researchers at Texas A&M discovered that in aggressive kidney cancers like tRCC, RNA forms liquid-like “droplet hubs” that switch on tumor genes and drive growth. They then engineered a nanobody-based molecular switch that dissolves these RNA condensates. In lab cells and mouse models, breaking the hubs halted tumor growth. The bigger idea: instead of targeting single genes, go after the RNA condensates that organize cancer’s machinery. That could open new treatments for pediatric and fusion-driven cancers.

Microscopic DNA “flowers” could deliver medicine exactly where it’s needed. 🌸🧬 Researchers at UNC Chapel Hill engineered tiny, shape-shifting soft robots made from DNA–inorganic hybrid crystals. These structures fold and unfold within seconds in response to environmental cues like acidity. Each flower’s DNA acts like a programmed circuit, guiding movement and chemical actions — enabling precise drug release, biopsy collection, or even blood-clot dissolution. Inspired by nature, this work pushes biology and robotics closer together, opening doors for smart medical therapies, environmental cleanup, and data storage.

Why does hair turn gray? It may be your body’s built-in cancer defense. 🧬🧑‍🦳 Researchers at the University of Tokyo found that pigment-producing stem cells respond to DNA damage by self-destructing — they mature, die off, and leave hair gray. It’s a protective move, removing damaged cells before they can turn dangerous. But under strong carcinogenic stress (UV, chemicals), this safety switch can fail. Those damaged cells may survive, multiply, and progress toward melanoma. In short: gray hair could be a small cosmetic trade-off for lower cancer risk.

Harvard’s Wyss Institute built a “breathing” human lung chip that could change how we test antivirals. 🧬💨 This organ-on-chip mimics real lung physiology and was used to evaluate a CRISPR RNA therapy against influenza A. The treatment cut viral levels by 50%+ and lowered inflammation with minimal off-target effects — strong antiviral action in a human-like setting. This approach lets researchers test gene therapies safely before moving to clinical trials, and it could accelerate pan-influenza treatments and pandemic preparedness by giving us rapid, realistic models of infection. #CRISPR #OrgansOnChips #RNAtherapy #GeneEditing #Virology

Thanks 🙏 ⁦@Google⁩ Copenhagen for hosting the #REBBLS Biotech Enablers. It was nice to talk about aptamers and AI to a diverse crowd.

It’s my cake day!!! 🍰 Wait wrong platform.. #MyXAnniversary

The 2025 Nobel Prize in Physiology or Medicine has been awarded to Mary E. Brunkow, Fred Ramsdell, and Shimon Sakaguchi for their discoveries on peripheral immune tolerance. Sakaguchi identified regulatory T cells in 1995, a crucial cell type that prevents autoimmune diseases. Brunkow and Ramsdell found that mutations in the Foxp3 gene cause severe autoimmune conditions, while Sakaguchi later demonstrated Foxp3's key role in regulatory T cell development. These findings advanced our understanding of self-tolerance, leading to new therapies for autoimmunity, cancer, and transplant success, with several treatments targeting regulatory T cells currently in clinical trials. #Immunology #Autoimmunity #MedicalResearch #ImmuneTolerance #Foxp3 #RegulatoryTcells #NobelLaureates #Medicine2025

What it’s like going to #FestivalOfBiologics as an aptamer company when everyone’s focused on antibodies 🧬😅” #Aptamers #Antibodies #Biotech #DrugDiscovery

mRNA technology is advancing HIV vaccine development. 🧬💉 Two studies using mRNA, similar to COVID vaccines, trained immune systems to recognize HIV’s outer proteins. The protein-carrier version triggered strong, lasting neutralizing antibodies in animals and early human trials. Some participants reported side effects like rashes, but results mark progress toward a vaccine for diverse HIV strains. More research is needed. #mRNA #HIV #Vaccines #biotechnews

Gene-edited cells show promise for Type 1 diabetes. 🧬🩺 A man with Type 1 diabetes for 37 years received donor cells engineered to evade immune attack, requiring no anti-rejection drugs. The cells survived 12 weeks, produced some insulin, and improved blood sugar markers. He still needs daily insulin, but this is a significant step toward cell therapies that could one day eliminate constant injections and immunosuppression. #Diabetes #CRISPR #GeneEditing #CellTherapy #biotechnews

Quantum computing achieved a biotech milestone. ⚛️🧬 IBM and Moderna used a quantum processor to simulate the folding of a 60-nucleotide mRNA, the longest sequence modeled on quantum hardware yet. mRNA shape determines function, but classical computers struggle with these complex 3D folds. This suggests quantum computing could address larger biological problems, speeding up vaccine and drug design. #QuantumComputing #mRNA #DrugDiscovery #Biotech
