wow. I don't think Vance is really this ignorant, which means he is lying in the most craven way imaginable
JD Vance: If you go back to WW2 or every major conflict in human history, they all ended with some kind of negotiation.

agree 100%. I just wrote about this same topic on Substack today (stevensalzberg.substack.com/…) nytimes.com/2026/06/09/opini…

A scary new move towards autocracy: @WHOMB wants to grab the power to approve or cancel any and all federal grants, at the whim of its Director, Russell Vought: stevensalzberg.substack.com/…

agreed. A very clear-headed piece by Sam Harris

A surprising finding: nearly all bacterial contamination in your grocery store's fresh or frozen chicken originates in a tiny number of breeders, not at the massive chicken breeding farms. We might be able to eliminate these contaminants cheaply pnas.org/doi/10.1073/pnas.25…

I've been to 100s of scientific conferences. I've never seen a technical talk get cheers, much less a standing ovation, but this result on pancreatic cancer really deserves it
Cheers, chills, and a standing ovation when RASolute 302 showed unprecedented survival on daraxonrasib for patients with progressive pancreatic cancer Seldom do you sense you’re witnessing a historic moment in cancer care but this feels like ras targeting has arrived #ASCO26

Congratulations Dr. Chao! Although he finished his Ph.D. last August, the official "hooding" ceremony at @HopkinsEngineer was yesterday, where Ela Pertea and I conferred the hood on @KuanHaoChao

hey #BOG26, I won't be there this year, but I wrote a column that attendees might enjoy. 2 months after the conversation described here, Craig Venter went to CSHL (May 1998) and announced his plans open.substack.com/pub/steven…

In 1998, I talked to Craig Venter about the feasibility of sequencing the human genome as a whole-genome shotgun project. Here's a story about that conversation stevensalzberg.substack.com/…

Wow, this is unexpected: Craig Venter passed away from side effects of cancer treatment. We had our differences, but we also co-authored many papers together in the late 90s and early 2000s. Sad news nytimes.com/2026/04/30/scien…

wow. Sometimes medical breakthroughs are truly great news. 30 years from discovering the gene to a treatment. One injection restores hearing for life - truly miraculous
A monumental moment in medical history: the first gene therapy for genetic hearing loss is now FDA approved. As a former Regeneron scientist, I feel very proud. I had the opportunity to hear about this programme while it was still in development. It’s one of the few programmes that, every time you came across it, you felt the medical breakthrough in your bones and privileged just to be there while it was happening. At this moment, it’s important that we look 30 years back when researchers mapped a locus on chromosome 2 to congenital deafness in a Lebanese family (pubmed.ncbi.nlm.nih.gov/8789…). They named it DFNB6 (later DFNB9) with no clue about the responsible gene. Three years later, the causal gene came to light: OTOF, encoding a protein called otoferlin (nature.com/articles/ng0499_3…). Seven years after that, in 2006, pioneering work by Christine Petit revealed that otoferlin is a calcium sensor in the inner hair cell membrane, acting as a molecular trigger that converts sound into electric signals that the brain can read (pubmed.ncbi.nlm.nih.gov/1705…). Twenty years fast forward, we now have a successful treatment. Thirty years from discovery to medicine. OTOF-related deafness is congenital, caused by complete deficiency of otoferlin. In these children, the cochlea is structurally intact, hair cells are there, the mechanics of sound transmission work. It’s just that final step, where hair cells hand off the signal to the auditory nerve through neurotransmitter release, that doesn’t happen. Sound arrives and dies at the synapse. It’s deafness due to a defect in the synapse caused by the absence of a single protein, which is what made this a beautiful, clean target for gene therapy. The treatment itself is a feat of molecular engineering. OTOF is too large to fit in a single AAV capsid. The team solved this elegantly by delivering the gene in two halves separately, which then get spliced to produce the full functional protein. A single surgical injection into the cochlea, a molecular miracle unfolds. Results from the CHORD trial were striking: of 20 evaluable patients, including children as young as 10 months, 80% showed meaningful hearing improvement, and by 48 weeks, 42% had achieved normal hearing including the ability to hear whispers. Otarmeni is not only the first gene therapy for deafness, it’s also the first dual-AAV therapy to be approved by the FDA. There are very few things in medicine that come close to giving back a sense like vision, hearing, or touch that a human never had from birth. It’s almost God’s work. A parent witnessing their child who was born deaf hearing their voice for the first time, it’s a joy that no words can describe. Multiply that by the fact that it came from a single injection, a repaired gene, and 30 years of science. We are truly in the golden era of medicine.

how sad that Marty Makary, who used to be a Hopkins doctor, now he just smiles as he lies to cover up RFK Jr.'s anti-vaccine nonsense, which led to cancellation of $500M in NIH support for RNA vaccine research
After the breathtaking results of an early mRNA pancreatic cancer vaccine trial, Dr Makary tells @kaitlancollins that NIH canceled $500 million in support for 20 mRNA vaccine trials simply because private industry should pay for it. In reality, RFK Jr killed the funding because he doesn’t believe in the technology. He said, β€œAfter reviewing the science and consulting top experts at NIH and FDA, HHS has determined that mRNA technology poses more risk than benefits for these respiratory viruses.”
