Thank you to Cancer Network for the feature. Rewriting the Hemoglobin Switch: CRISPR Targeting in Sickle Cell Disease Gene editing has moved from concept to clinic. By leveraging CRISPR to reactivate fetal hemoglobin, we’re no longer just managing SCD—we’re aiming to rewrite its biology.

Rewriting the Hemoglobin Switch: CRISPR Targeting in Sickle Cell Disease | CancerNetwork

The RUBY trial demonstrates that disrupting the BCL11A binding site in the γ-globin promoters can normalize hemoglobin in severe sickle cell disease.

Exercise isn’t just supportive care anymore—it’s becoming therapeutic. In the latest episode of The Translational Edge, we explore how exercise is quietly reshaping cancer care—impacting outcomes, biology, and survivorship in ways we’re only beginning to understand.

Thank you to Cancer Network for highlighting: Reprogramming T Cells: The Promise of In Vivo Site-Specific CAR Engineering CAR T therapy—without the lab. A single infusion. Precise genome integration. T cells engineered in vivo. This is how we scale cellular therapy.

🧠⚕️ Beyond board exams: evaluating AI for real-world medicine Large language models can ace medical licensing exams—but that says little about how they perform in day-to-day clinical practice. Enter MedHELM, a new framework designed to evaluate medical AI where it actually matters.

Holistic evaluation of large language models for medical tasks with MedHELM - Nature Medicine

MedHELM, an extensible evaluation framework including a new taxonomy for classifying medical tasks and a benchmark of many datasets across these categories, enables the evaluation of large language mo...

🧠💥 Decoding how opioids relieve pain—beyond sensation New work reveals how the anterior cingulate cortex (ACC) encodes the affective dimension of chronic pain—and how opioids selectively modulate this circuit.

Mimicking opioid analgesia in cortical pain circuits - Nature

The anterior cingulate cortex encodes affective pain behaviours modulated by opioids; targeting opioid-sensitive neurons through a new chemogenetic gene therapy replicates the analgesic effects of mor...
