Good morning, and happy Halloween. Fitting, since yesterday the site covered a vaccine meant to hunt down aging's "zombie" cells, a gene that let old mice live longer and the first age-reversal therapy tested in people. Today's big one is our Halloween special: the real-life parts list for Frankenstein's lab.
The big one
Frankenstein was just early. How the future is being built by mad scientists. Nearly every piece of Victor Frankenstein's lab now exists for real. Minnesota researchers froze a pig kidney into glass for just over a year, warmed it up, and it made urine. A gene-edited pig kidney kept one man off dialysis for 271 days until a human kidney came. A Yale system restarted circulation and some cell function in pig organs an hour after death. Harvard kept lab-grown human mini-brains alive for nearly six years, and a de-extinction company says its dire wolves just turned two.
Why it matters: nobody is building a monster. Put together, these parts point to something far friendlier: a bank of frozen, revivable organs where organs wait for people instead of people waiting for organs. It's Some Assembly Required #3. Read it →
Yesterday on the site
The End of Aging
AI Could Unlock a Real Tan Without the Sun, or the Sun Damage: a rub-on molecule darkened human skin in a dish in 2017, and AI drug design could finally get it out of the lab.
Age-Reversal Therapy Clears Its First Safety Test in Humans: no serious side effects in three patients, and a dose three times higher is cleared to go next.
AI Found a Gene That Let Old Mice Live Longer: AI is starting to point researchers at aging levers humans hadn't thought to pull.
Old-Age Weakness May Have Switches Scientists Can Flip: two specific switches behind weak old muscle give drug makers real targets, and one drug is headed for a trial in older adults.
Immune Cells Could Be Trained to Kill Aging's 'Zombie' Cells: an AI-designed peptide turned the body's own killer cells against worn-out cells in the lab, a third route to clearing them.
Hormones Steer How Skin Renews, a New Clue to Keeping It Young: in mice, sex hormones set the rules skin stem cells follow, a hint that skin repair could be tailored to each person.
The End of Disease
A Pill That Could Slow Alzheimer's Gets Its Verdict in Weeks: a pill that lowers the stress hormone inside brain cells reports its pivotal results in mid-November.
A Nose Spray for Alzheimer's Has Finished Its Trial: it goes after inflamed brain immune cells instead of plaques, with results due early next year.
A One-Shot Gene Fix for Muscle-Wasting Disease Reached Boys' Muscles: the editor worked in three boys, but a fourth died from a reaction blamed on the delivery virus, and safer delivery is now the race.
Thinking Machines
Did AI Just Overturn a Rule Hundreds of Computer Science Papers Rely On? Experts Are Checking: if the proof holds, it's a machine-made result experts couldn't produce themselves.
Robots & Self-Driving
Fully Robotic Cars With No Steering Wheel Are Heading to Dallas: Tesla says its pedal-free Cybercab reaches a second city in November.
Air Taxis Just Got Their First Federal Permit: an electric air taxi can now fly buyers around, the first step toward selling seats.
Limitless Energy
Electric Cars Could Double Their Driving Range: the world's biggest battery maker doubled the size of its liquid-free test cells.
A $500 Million Bet on Batteries That Need No Lithium: one supplier is building for sodium batteries at enormous scale, a cheaper way to store power.
Sci-Fi Tech
Full-Color Screens Now Fit in Sunglasses: 55-gram glasses with a full-color display put a real screen in an ordinary-looking frame.
To the Stars
Starship Just Lit All Six Engines on the Ground. Next Stop: Space.: the last engine test before SpaceX tries to catch the top half of Starship with its launch tower.
Already up this morning
The Speed of Aging May Be Set by the Bugs in Our Gut: if a microbe moves the aging clock, a probiotic or diet could be tested in months, not decades.
Wrinkle Cream, but Make It Mitochondria: Eye Wrinkles Shrank in 8 Weeks: a cream that triggers cleanup of worn-out cell power plants made eye wrinkles shallower.
Sunglasses With a Movie Theater Inside Just Went on Sale: the first glasses on Google's Android XR platform are on sale from $1,099.
By the numbers
108 days: how much one dose of an AI-picked gene added to the median life of old mice, from 778 days to 886, in a study of 19 mice.
55 grams: the weight Rokid claims for its full-color display glasses, a little more than two AA batteries.
456: Starship launches a year SpaceX has asked to fly from Texas, against 25 allowed now.
New on the odds board
Yesterday's posts put fresh odds on a paying passenger riding an air taxi in a U.S. city, SpaceX catching Starship's upper stage with its tower, another lab repeating the AI-picked gene's lifespan gain in mice, and a one-time CRISPR treatment for Duchenne muscular dystrophy reaching patients. Paid readers see the numbers inside each post.
On the calendar
Nov. 4 to 7: the Gerontological Society of America's annual meeting in National Harbor, Md., the next big date on the aging-research calendar.
Nov. 9: CRISPR Therapeutics presents new human data on its one-dose gene editor for high triglycerides.
Mid-November: XREAL's Aura glasses start shipping, and results arrive for the Xanamem Alzheimer's pill. On Nov. 16, a second Alzheimer's pill, AriBio's AR1001, reports results from 1,535 people.
November, no day set: Starship Flight 15 and the first attempt to catch the ship with the tower, pending regulators' approval. Public FAA meetings on SpaceX's request for more launches run Nov. 17 to 19.
The story we're following
Digital patients: no new development since Thursday. We're still watching for the first regulator to let a computer model stand in for real patients in a final trial.
Quote of the day
