The First Cloned Monkeys Provoked More Shrugs Than Shocks
A few months ago, it was announced that not one, but two healthy long-tailed macaque monkeys were cloned—a first for primates of any kind. The cells were sourced from aborted monkey fetuses and the DNA transferred into eggs whose nuclei had been removed, the same method that was used in 1996 to clone "Dolly the Sheep." Two live births, females named Zhong Zhong and Hua Hua, resulted from 60 surrogate mothers. Inefficient, it's true. But over time, the methods are likely to be improved.
The scientist who supervised the project predicts that cloning, along with gene editing, will result in "ideal primate models" for studying disease mechanisms and drug screening.
Dr. Gerald Schatten, a famous would-be monkey cloner, authored a controversial paper in 2003 describing the formidable challenges to cloning monkeys and humans, speculating that the feat might never be accomplished. Now, some 15 years later, that prediction, insofar as it relates to monkeys, has blown away.
Zhong Zhong and Hua Hua were created at the Chinese Academy of Science's Institute of Neuroscience in Shanghai. The Institute founded in 1999 boasts 32 laboratories, expanding to 50 labs in 2020. It maintains two non-human primate research facilities.
The founder and director, Dr. Mu-ming Poo, supervised the project. Poo is an extremely accomplished senior researcher at the pinnacle of his field, a distinguished professor emeritus in Biology at UC Berkeley. In 2016, he was awarded the prestigious $500,000 Gruber Neuroscience Prize. At that time, Poo's experiments were described by a colleague as being "innovative and very often ingenious."
Poo maintains the reputation of studying some of the most important questions in cellular neuroscience.
But is society ready to accept cloned primates for medical research without the attendant hysteria about fears of cloned humans?
By Western standards, use of non-human primates in research focuses on the welfare of the animal subjects. As PETA reminds us, there is a dreadful and sad history of mistreatment. Dr. Poo assures us that his cloned monkeys are treated ethically and that the Institute is compliant with the highest regulatory standards, as promulgated by the U.S. National Institutes of Health.
He presents the noblest justifications for the research. He predicts that cloning, along with gene editing, will result in "ideal primate models" for studying disease mechanisms and drug screening. He declares that this will eventually help to solve Parkinson's, Huntington's and Alzheimer's disease.
But is society ready to accept cloned primates for medical research without the attendant hysteria about fears of cloned humans? It appears so.
While much of the news coverage expressed this predictable worry, my overall impression is that the societal response was muted. Where was the expected outrage? Then again, we've come a long way since Dolly the Sheep in terms of both the science and the cultural acceptance of cloning. Perhaps my unique vantage point can provide perspective on how much attitudes have evolved.
Perhaps my unique vantage point can provide perspective on how much attitudes have evolved.
I sometimes joke that I am the world's only human cloning lawyer—a great gig but there are still no clients.
I first crashed into the cloning scene in 2002 when I sued the so-called human cloning company "Clonaid" and asked in court to have a temporary guardian appointed for the alleged first human clone "Baby Eve." The claim needed to be tested, and mine was the first case ever aiming to protect the rights of a human clone. My legal basis was child welfare law, protecting minors from abuse, negligence, and exploitation.
The case had me on back-to-back global television broadcasts around the world; there was live news and "breathless" coverage at the courthouse emblazoned in headlines in every language on the planet. Cloning was, after all, perceived as a species-altering event: asexual reproduction. The controversy dominated world headlines for month until Clonaid's claim was busted as the "fakest" of fake news.
Fresh off the cloning case, the scientific community reached out to me, seeing me as the defender of legitimate science, an opponent of cloning human babies but a proponent of using cloning techniques to accelerate ethical regenerative medicine and embryonic stem cell research in general.
The years 2003 to 2006 were the era of the "stem cell wars" and a dominant issue was human cloning. Social conservative lawmakers around the world were seeking bans or criminalization not only of cloning babies but also the cloning of cells to match the donor's genetics. Scientists were being threatened with fines and imprisonment. Human cloning was being challenged in the United Nations with the United States backing a global treaty to ban and morally condemn all cloning -- including the technique that was crucial for research.
Scientists and patients were touting the cloning technique as a major biomedical breakthrough because cells could be created as direct genetic matches from a specific donor.
At the same time, scientists and patients were touting the cloning technique as a major biomedical breakthrough because cells could be created as direct genetic matches from a specific donor.
So my organization organized a conference at UN headquarters to defend research cloning and all the big names in stem cell research were there. We organized petitions to the UN and faxed 35,000 signatures to the country mission. These ongoing public policy battles were exacerbated in part because of the growing fear that cloning babies was just around the corner.
Then in 2005, the first cloned dog stunned the world, an Afghan hound named Snuppy. I met him when I visited the laboratories of Professor Woo Suk Hwang in Korea. His minders let me hold his leash -- TIME magazine's scientific breakthrough of the year. He didn't lick me or even wag his tail; I figured he must not like lawyers.
Tragically, soon thereafter, I witnessed firsthand Dr. Hwang's fall from grace when his human stem cell cloning breakthroughs proved false. The massive scientific misconduct rocked the nation of Korea, stem cell science in general, and provoked terrible news coverage.
Nevertheless, by 2007, the proposed bans lost steam, overridden by the advent of a Japanese researcher's Nobel Prize winning formula for reprogramming human cells to create genetically matched cell lines, not requiring the destruction of human embryos.
After years of panic, none of the recent cloning headlines has caused much of a stir.
Five years later, when two American scientists accomplished therapeutic human cloned stem cell lines, their news was accepted without hysteria. Perhaps enough time had passed since Hwang and the drama was drained.
In the just past 30 days we have seen more cloning headlines. Another cultural icon, Barbara Streisand, revealed she owns two cloned Coton de Tulear puppies. The other weekend, the television news show "60 Minutes" devoted close to an hour on the cloned ponies used at the top level of professional polo. And in India, scientists just cloned the first Assamese buffalo.
And you know what? After years of panic, none of this has caused much of a stir. It's as if the future described by Alvin Toffler in "Future Shock" has arrived and we are just living with it. A couple of cloned monkeys barely move the needle.
Perhaps it is the advent of the Internet and the overall dilution of wonder and outrage. Or maybe the muted response is rooted in popular culture. From Orphan Black to the plotlines of dozens of shows and books, cloning is just old news. The hand-wringing discussions about "human dignity" and "slippery slopes" have taken a backseat to the AI apocalypse and Martian missions.
We humans are enduring plagues of dementia and Alzheimer's, and we will need more monkeys. I will take mine cloned, if it will speed progress.
Personally, I still believe that cloned children should not be an option. Child welfare laws might be the best deterrent.
The same does not hold for cloning monkey research subjects. Squeamishness aside, I think Zhong Zhong and Hua Hua will soon be joined by a legion of cloned macaques and probably marmosets.
We humans are enduring plagues of dementia and Alzheimer's, and we will need more monkeys. I will take mine cloned, if it will speed the mending of these consciousness-destroying afflictions.
Scientific revolutions once took centuries, then decades, and now seem to bombard us daily. The convergence of technologies has accelerated the future. To Zhong Zhong and Hua Hua, my best wishes with the hope that their sacrifices will contribute to the health of all primates -- not just humans.
A startup aims to make medicines in space
Story by Big Think
On June 12, a SpaceX Falcon 9 rocket deployed 72 small satellites for customers — including the world’s first space factory.
The challenge: In 2019, pharma giant Merck revealed that an experiment on the International Space Station had shown how to make its blockbuster cancer drug Keytruda more stable. That meant it could now be administered via a shot rather than through an IV infusion.
The key to the discovery was the fact that particles behave differently when freed from the force of gravity — seeing how its drug crystalized in microgravity helped Merck figure out how to tweak its manufacturing process on Earth to produce the more stable version.
Microgravity research could potentially lead to many more discoveries like this one, or even the development of brand-new drugs, but ISS astronauts only have so much time for commercial experiments.
“There are many high-performance products that are only possible to make in zero-gravity, which is a manufacturing capability that cannot be replicated in any factory on Earth.”-- Will Bruey.
The only options for accessing microgravity (or free fall) outside of orbit, meanwhile, are parabolic airplane flights and drop towers, and those are only useful for experiments that require less than a minute in microgravity — Merck’s ISS experiment took 18 days.
The idea: In 2021, California startup Varda Space Industries announced its intention to build the world’s first space factory, to manufacture not only pharmaceuticals but other products that could benefit from being made in microgravity, such as semiconductors and fiber optic cables.
This factory would consist of a commercial satellite platform attached to two Varda-made modules. One module would contain equipment capable of autonomously manufacturing a product. The other would be a reentry capsule to bring the finished goods back to Earth.
“There are many high-performance products that are only possible to make in zero-gravity, which is a manufacturing capability that cannot be replicated in any factory on Earth,” said CEO Will Bruey, who’d previously developed and flown spacecraft for SpaceX.
“We have a team stacked with aerospace talent in the prime of their careers, focused on getting working hardware to orbit as quickly as possible,” he continued.
“[Pharmaceuticals] are the most valuable chemicals per unit mass. And they also have a large market on Earth.” -- Will Bruey, CEO of Varda Space.
What’s new? At the time, Varda said it planned to launch its first space factory in 2023, and, in what feels like a first for a space startup, it has actually hit that ambitious launch schedule.
“We have ACQUISITION OF SIGNAL,” the startup tweeted soon after the Falcon 9 launch on June 12. “The world’s first space factory’s solar panels have found the sun and it’s beginning to de-tumble.”
During the satellite’s first week in space, Varda will focus on testing its systems to make sure everything works as hoped. The second week will be dedicated to heating and cooling the old HIV-AIDS drug ritonavir repeatedly to study how its particles crystalize in microgravity.
After about a month in space, Varda will attempt to bring its first space factory back to Earth, sending it through the atmosphere at hypersonic speeds and then using a parachute system to safely land at the Department of Defense’s Utah Test and Training Range.
Looking ahead: Ultimately, Varda’s space factories could end up serving dual purposes as manufacturing facilities and hypersonic testbeds — the Air Force has already awarded the startup a contract to use its next reentry capsule to test hardware for hypersonic missiles.
But as for manufacturing other types of goods, Varda plans to stick with drugs for now.
“[Pharmaceuticals] are the most valuable chemicals per unit mass,” Bruey told CNN. “And they also have a large market on Earth.”
“You’re not going to see Varda do anything other than pharmaceuticals for the next minimum of six, seven years,” added Delian Asparouhov, Varda’s co-founder and president.
Genes that protect health with Dr. Nir Barzilai
In today’s podcast episode, I talk with Nir Barzilai, a geroscientist, which means he studies the biology of aging. Barzilai directs the Institute for Aging Research at the Albert Einstein College of Medicine.
My first question for Dr. Barzilai was: why do we age? And is there anything to be done about it? His answers were encouraging. We can’t live forever, but we have some control over the process, as he argues in his book, Age Later.
Dr. Barzilai told me that centenarians differ from the rest of us because they have unique gene mutations that help them stay healthy longer. For most of us, the words “gene mutations” spell trouble - we associate these words with cancer or neurodegenerative diseases, but apparently not all mutations are bad.

Centenarians may have essentially won the genetic lottery, but that doesn’t mean the rest of us are predestined to have a specific lifespan and health span, or the amount of time spent living productively and enjoyably. “Aging is a mother of all diseases,” Dr. Barzilai told me. And as a disease, it can be targeted by therapeutics. Dr. Barzilai’s team is already running clinical trials on such therapeutics — and the results are promising.
More about Dr. Barzilai: He is scientific director of AFAR, American Federation for Aging Research. As part of his work, Dr. Barzilai studies families of centenarians and their genetics to learn how the rest of us can learn and benefit from their super-aging. He also organizing a clinical trial to test a specific drug that may slow aging.
