🔍DEEP DIVE

A Cure Meant for One

If a gene edit could save your life… but had never been tested on anyone else… would you still say yes?

In 2022, 27-year-old Terry Horgan became the first person to receive a personalized CRISPR therapy built just for him. He had Duchenne muscular dystrophy, a brutal, incurable disease that wastes muscle away. His brother, Richard, wasn’t ready to lose him.

Richard founded Cure Rare Disease, partnered with Yale researchers, and helped develop an experimental therapy using CRISPR to activate backup copies of dystrophin, the gene Terry's body desperately needed.

It was approved by the FDA after 3 years of development as an n-of-1 trial, the first of its kind. But just days after receiving it, Terry’s condition worsened. He went into rapid respiratory failure and passed away.

He never had a chance to show whether the CRISPR worked.

Later reports suggested the likely cause wasn’t the gene-editing tech, but the vector. The high dose of AAV (adeno-associated virus) used to deliver the therapy may have triggered a lethal immune response. Terry’s muscles were already fragile. His body couldn’t recover.

It's hard to imagine saying no. Not because you're reckless, but because when death is certain and a cure is possible, the question stops being 'is this safe?' and starts being 'can I live with not trying?’

Terry tried. The therapy failed him, but his courage didn't. That's what stays.

⚡QUICK CUTS

Scientists Made Rage-Mutant Hamsters

In 2022, researchers at Georgia State used CRISPR to delete a gene tied to aggression and created something far worse.

They knocked out Avpr1a, a receptor for vasopressin, the brain’s social signaling hormone. The goal? Make hamsters more peaceful.

Instead, they turned into tiny hyper-aggressive mutants. 

Put in same-sex cages, the edited hamsters fought more, bit more, and showed much more dominance behaviors than normal ones. Even their scent-marking, used for territory and flirting, skyrocketed.

It broke all the predictions. Scientists thought removing vasopressin signaling would blunt aggression. After all, drugs blocking it often calm rodents. But evolution doesn’t design with single switches. The receptor seems to integrate multiple pathways for stress, bonding, and dominance. Knock it out, and the brain doesn’t go quiet. It rewires in unpredictable ways.

And that’s the lesson: Genes don’t act alone. They’re part of massive, tangled circuits, where one change can ripple across the whole system.

So when we edit the brain without understanding the full network? It may come with massive unintended consequences.

The $330,000 Burger

In 2013, Dutch scientists cooked the world’s first lab-grown burger live on stage in London. Price tag: $330,000. It was funded by Google co-founder Sergey Brin and built from cow muscle cells grown in a petri dish — no slaughter, no herd, no methane.

The verdict was that it tasted like meat. Because it was meat. Just meat without the animal. One food critic called it “close, but not juicy.” Another said it was indistinguishable from the real thing.

At the time, it felt like a biotech stunt. But it proved one radical idea: meat doesn’t need a heartbeat to end up on your plate. Scientists had shown that a handful of stem cells, given the right nutrients and growth factors, could multiply into thousands of muscle fibers.

What once took an entire animal could now be done in a steel tank. Within a decade, costs dropped from hundreds of thousands to under $10 a patty in pilot runs.

That burger lit the fuse. It launched an industry now backed by billions: Mosa Meat, GOOD Meat, Believer Meats, Aleph Farms, and dozens more. Today, lab-grown chicken is already on a few menus in the U.S. and Singapore.

The promise? Protein without cruelty. Burgers without slaughterhouses. Steak without climate collapse. The question now isn’t if lab-grown meat will scale. It’s how fast it replaces the farm.

🧠 BRIEF BYTE

Your gut is home to over 100 trillion microbes, vastly outnumbering your human cells.

Most biotech startups build one therapy. ElevateBio is building an entire factory of futures.

Think of it as a power plant for genetic medicine. Instead of betting on a single cure, ElevateBio is creating the infrastructure (labs, delivery systems, manufacturing platforms) that dozens of other companies plug into. Their portfolio spans cell therapies, gene editing, RNA medicines, and beyond.

At the heart of it is BaseCamp, a 140,000-square-foot engine in Cambridge designed to solve the hardest bottleneck in biotech: making these therapies at scale. Instead of each startup reinventing the wheel, ElevateBio standardizes the toughest steps (viral vectors, cell engineering, GMP manufacturing) on shared industrial pipelines. By centralizing those capabilities, they cut years off timelines and slash costs that would sink most young companies trying to build alone.

It’s where CRISPR edits move from concept to clinic, where rare disease treatments get manufactured for first-ever patients, and where entire new startups are spun out like satellites from a mothership.

In an industry where brilliant science often dies in the “valley of death” between discovery and production, ElevateBio is building the bridge. Not just a company, but a platform of platforms — one that could quietly reinforce the entire next era of medicine.

If they’re right, the future of gene editing won’t just be discovered in labs. It’ll be launched from ElevateBio’s.

YOUR TURN

If a therapy had never been tested in humans, but it was your only shot — would you still take it?

Featured Take

Should scientists be allowed to give animals disorders in the name of research?

“It feels messed up that we’d literally give animals disorders just to study them. At some point you gotta ask if we are learning more about science, or about how far humans will go.”
