The First CRISPR Patients Are Living Better: Why That Matters After 2020

It’s been a while since I’ve talked about CRISPR, biotechnology, and the prospect of ordinary people enhancing their biology in ways straight out of a comic book. In my defense, this past year has created plenty of distractions. Some have been so bad that my usual optimism of the future has been seriously damaged.

While my spirit is wounded, I still have hope that science and technology will continue to progress. If anything, it’ll progress with more urgency after this year. A great many fields are bound to get more attention and investment after the damage done by a global pandemic.

We can’t agree on much, but we can at least agree on this. Pandemics are bad for business, bad for people, bad for politics, and just objectively awful for everyone all around, no matter what their station is in life.

There’s a lot of incentive to ensure something like this never happens again is what I’m saying. While we’re still a long way from ending pandemics entirely, we already have tools that can help in that effort. One is CRISPR, a promising tool I’ve talked about in the past. While it wasn’t in a position to help us during this pandemic, research into refining it hasn’t stopped.

Despite all the awful health news of this past year, some new research has brought us some promising results on the CRISPR front. In terms of actually treading real people who have real conditions, those results are in and they give us reason to hope.

One such effort involved using CRISPR to help treat people with Sickle Cell Disease, a genetic condition that hinders the ability of red blood cells to carry oxygen. It affects over 4 million people worldwide and often leads to significant complications that can be fatal.

Since CRISPR is all about tweaking genetics, it’s a perfect mechanism with which to develop new therapies. Multiple patients have undergone experimental treatments that utilize this technology. In a report form NPR, the results are exceeding expectations for all the right reasons.

NPR: First Patients To Get CRISPR Gene-Editing Treatment Continue To Thrive

At a recent meeting of the American Society for Hematology, researchers reported the latest results from the first 10 patients treated via the technique in a research study, including Gray, two other sickle cell patients and seven patients with a related blood disorder, beta thalassemia. The patients now have been followed for between three and 18 months.

All the patients appear to have responded well. The only side effects have been from the intense chemotherapy they’ve had to undergo before getting the billions of edited cells infused into their bodies.

The New England Journal of Medicine published online this month the first peer-reviewed research paper from the study, focusing on Gray and the first beta thalassemia patient who was treated.

“I’m very excited to see these results,” says Jennifer Doudna of the University of California, Berkeley, who shared the Nobel Prize this year for her role in the development of CRISPR. “Patients appear to be cured of their disease, which is simply remarkable.”

Make no mistake. This is objectively good news and not just for people suffering from sickle cell disease.

Whenever new medical advances emerge, there’s often a wide gap between developing new treatments and actually implementing them in a way that makes them as commonplace as getting a prescription. The human body is complex. Every individual’s health is different. Taking a treatment from the lab to a patient is among the biggest challenge in medical research.

This news makes it official. CRISPR has made that leap. The possible treatments aren’t just possibilities anymore. There are real people walking this planet who have received this treatment and are benefiting because of it. Victoria Gray, as referenced in the article, is just one of them.

That’s another critical threshold in the development of new technology. When it goes beyond just managing a condition to helping people thrive, then it becomes more than just a breakthrough. It becomes an opportunity.

It sends a message to doctors, researchers, and biotech companies that this technology works. Some of those amazing possibilities that people like to envision aren’t just dreams anymore. They’re manifesting before our eyes. This is just one part of it. If it works for people with Sickle Cell Disease, what other conditions could it treat?

I doubt I’m the first to ask that question. As I write this, there are people far smarter and more qualified than me using CRISPR to develop a whole host of new treatments. After a year like 2020, everyone is more aware of their health. They’re also more aware of why science and medicine matter. It can do more than just save our lives. It can help us thrive.

We learned many hard lessons in 2020, especially when it comes to our health. Let’s not forget those lessons as we look to the future. This technology is just one of many that could help us prosper in ways not possible in previous years. We cheered those who developed the COVID-19 vaccine. Let’s start cheering those working on new treatments with CRISPR.

Why Biological Weapons Will Be A (MUCH) Bigger Threat In The Future


It wasn’t too long ago that the biggest existential threat facing humanity was nuclear war. I’ve noted before how distressingly close we’ve come to a nuclear disaster and how the threat of a nuclear holocaust is still present. However, that threat has abated in recent decades, especially as nuclear weapons have gotten so destructive that their use is somewhat redundant.

More recently, people have become more concerned about the threat posed by advanced artificial intelligence. The idea is that at some point, an AI will become so intelligent and capable that we won’t be able to stop it in the event it decides that humanity must go extinct. It’s the basis of every Terminator movie, as well as an Avengers movie.

While I certainly have my concerns about the dangers of advanced artificial intelligence, it’s not the threat that worries me most these days. We still have some measure of control over the development of AI and we’re in a good position to guide that technology down a path that won’t destroy the human race. The same cannot be said for biological weapons.

If there’s one true threat that worries me more with each passing day, it’s that. Biological weapons are one of those major threats that does not slip under the radar, as evidenced by plenty of movies, books, and TV shows. However, the extent of that threat has become more understated in recent years and has the potential to be something more powerful than nuclear weapons.

By powerful, I don’t necessarily mean deadlier. At the end of the day, nuclear weapons are still more capable of rendering the human race extinct and turning the whole planet into a radioactive wasteland. The true power of biological weapons less about how deadly they can be and more about how useful they could be to potential governments, tyrants, or extremists.

For most of human history, that power has been limited. There’s no question that disease has shaped the course of human history. Some plagues are so influential that they mark major turning points for entire continents. The same can be said for our ability to treat such diseases. However, all these diseases had one fatal flaw that kept them from wiping out the human race.

Thanks to the fundamental forces of evolution, a deadly pathogen can only be so deadly and still survive. After all, an organism’s ultimate goal isn’t to kill everything it encounters. It’s to survive and reproduce. It can’t do that if it kills a carrier too quickly. If it’s too benign, however, then the carrier’s immune system will wipe it out.

That’s why even diseases as deadly as Ebola and Influenza can only be so infectious. If they kill all their hosts, then they die with them. That’s why, much to the chagrin of creationists, evolution doesn’t favor the natural emergence of apocalyptic diseases. They can still devastate the human race, but they can’t necessarily wipe it out. It would only wipe itself out in the process and most lifeforms avoid that.

It’s also why the large-scale biological weapons programs of the 20th century could only be so effective. Even if a country manufactured enough doses of an existing disease to infect every person on the planet, it won’t necessarily be deadly enough to kill everyone. Even at its worst, smallpox and bubonic plague never killed more than two-thirds of those it infected.

That’s not even factoring in how difficult it is to distribute these pathogens to everyone without anyone noticing. It’s even harder today because powerful governments invest significant resources into preventing and containing an outbreak. If large numbers of people start getting sick and dropping dead at a rapid rate, then someone will notice and take action.

That’s why, for the most part, biological weapons are both ethically untenable and not very useful as weapons of mass destruction. They’re difficult to control, difficult to distribute, and have unpredictable effects. They also require immense resources, considerable technical know-how, and a keen understanding of science. Thankfully, these are all things that extreme religious zealots tend to lack.

For the most part, these powerful constraints have kept biological weapons from being too great a threat. However, recent advances in biotechnology could change that and it’s here where I really start to worry. With recent advances in gene-editing and the emergence of tools like CRISPR, those limitations that kept biological weapons in check may no longer be insurmountable.

While I’ve done plenty to highlight all the good that tools like CRISPR could do, I don’t deny that there are potential dangers. Like nuclear weapons, this technology is undeniably powerful and powerful technology always carries great risks. With CRISPR, the risks aren’t as overt as obvious as fiery mushroom clouds, but they can be every bit as deadly.

In theory, CRISPR makes it possible to cut and paste genetic material with the same ease as arranging scattered puzzle pieces. With right materials and tools, this technology could be used to create genetic combinations in organisms that could never occur naturally or even with artificial selection.

Imagine a strain of smallpox that was lethal 100 percent of the time and just as infectious.

Imagine a strain of the flu that was as easy to spread as the common cold, but as deadly as bubonic plague.

Imagine a strain of an entirely new pathogen that is extremely lethal and completely immune to all modern medicine.

These are all possible, albeit exceedingly difficult, with genetic editing. Unlike nuclear weapons, it doesn’t require the procurement of expensive and dangerous elements. It just needs DNA, RNA, and a lab with which to produce them. It’s a scary idea, but that’s actually not the worst of it, nor is it the one that worries me most.

A doomsday bioweapon like that might be appealing to generic super-villains, but like nuclear weapons, they’re not very strategic because they kill everyone and everything. For those with a more strategic form of blood-lust, advanced biological weapons offer advantages that sets them apart from any other weapon.

Instead of a pathogen infecting everyone it comes into contact with, what if it only infected a certain group of people that carry a specifics traits associated with a particular race or ethnic group? What if someone wanted to be even more strategic than that and craft a pathogen that attacked only one specific person?

In principle, this is possible if you can manipulate the genetics of a disease in just the right way. Granted, it’s extremely difficult, but the potential utility makes it more useful than a nuclear bomb will ever be.

Suddenly, a government or terrorist organization doesn’t need a skilled assassin on the level of James Bond to target a specific person or group. They just need the right genetic material and a working knowledge of how to program it into a synthetic pathogen. It could even be made to look like a completely different disease, which ensured it didn’t raise any red flags.

It’s not the ultimate weapon, but it’s pretty darn close. Biological weapons with this level of refinement could potentially target entire groups of people and never put the attackers at risk. As a strategy, it can effectively end an entire conflict without a shot being fired. Those infected wouldn’t even know it was fired if the pathogen were effectively distributed.

It’s one of those weapons that both terrorists and governments would be tempted to use. The most distressing part is they could use it in a way that’s difficult to detect, let alone counter. Even after all the death and destruction has been wrought, how do you even prove that it was a result of a bioweapon? Even if you could prove that, how would you know who made it?

These are the kinds of questions that only have disturbing answers. They’re also the reasons why I believe biological weapons are poised to become a far bigger issue in the coming years. Even if it’s unlikely they’ll wipe out the human race, they can still cause a special kind of destruction that’s almost impossible to counter.

Unlike any other weapon, though, the destruction could be targeted, undetectable, and unstoppable. Those who wield this technology would have the power to spread death with a level of precision and tact unprecedented in human history. While I believe that humanity will eventually be able to handle dangerous technology like artificial intelligence, I doubt it’ll ever be capable of handling a weapon like that.

Why Designer Babies Are NOT The Same As Eugenics


As much as I celebrate advances in science and technology, I don’t deny there are instances where some advances it leads to unintended consequences. I’m sure the inventor of ski masks knows that all too well. In many cases, these missteps and mishaps are part of the ongoing challenge to use these advances responsibly. It’s akin to a maturation process that is often difficult, but still necessary.

In some cases, however, certain advances bring out some of humanity’s ugliest traits. Whether it’s a tool or an insight into the natural world, certain people who may or may not be malicious will use science to further a nefarious agenda. Of all the sciences that brought out the worst in humanity, eugenics is probably the most well-known.

The concept, itself, is not entirely abhorrent. If you look up the definition, this is what comes up.

The practice or advocacy of controlled selective breeding of human populations to improve the population’s genetic composition.

On paper, that has some objective merit. The world is a chaotic, dangerous place that’s constantly changing. In some cases, humanity is causing that change. If we’re to survive on a planet in which 99 percent of the species that have ever lived have gone extinct, it makes sense to improve our collective genetics so that we’re best equipped to survive.

Unfortunately, the details surrounding eugenics were permanently tainted when it became the preferred excuse for atrocities by the Nazis. Even before that, it was a popular talking point among racists seeking to marginalize or outright exterminate the impact of certain minorities within a society. At one point, there were organizations dedicated to promoting eugenics through forced sterilization and miscegenation laws.

The legacy of eugenics is so ugly that it’s almost synonymous with some of the worst acts of bigotry ever committed. When people think of eugenics, they don’t think of advancing human biology to make it more robust. They imagine racist tyrants forcibly sterilizing undesirable minorities in the hopes that they eventually die out in a silent genocide.

There’s no question that this form of eugenics is abhorrent. The way it was practiced throughout the 20th century was a perversion of science and technology. We would be wise to remember that as we make bigger and bolder advancements in science, especially for those related to biotechnology.

It’s here where the ugly legacy of eugenics seems destined to clash with science once more. In late 2018, news broke of a groundbreaking advance in biotechnology when a scientist named He Jiankui announced that the first genetically modified humans had been born. I went out of my way to note why this is a huge deal in the history of our species, but it’s also sparking distressing concerns related to eugenics.

Thanks to gene-editing tools like CRISPR, it’s now possible to edit the human genome with the same ease as copying and pasting text from a website. That has sparked concerns that it will be used to purge certain undesirables from the human population, just as was attempted with eugenics.

Logistically, there’s no reason why tools like CRISPR couldn’t be used to edit the genome of every child before they’re born to ensure they look a certain way. Granted, it would require some fairly invasive policies, but that has never stopped ambitious governments in the past. As these tools are refined, it’ll only get easier to pursue the kinds of racist policies that deplorable bigots in the past once favored.

However, this is not a fair association, nor is it constructive in addressing the legitimate issues surrounding the use of CRISPR and so-called designer babies. Linking this technology to eugenics is akin to blaming every nuclear physicist for the destruction of Hiroshima and Nagasaki. It’s not just because the potential of this technology is so great. The intent behind it differs considerably with that of eugenics.

That intent shows in the specifics of the first two genetically modified children. These children were not born out of a desire for racial superiority. The modifications made to their genome was intended to make them more resistant to HIV/AIDS infection. That’s an objective good. Healthier babies who are more resistant to disease is a benefit to our species, as a whole.

In addition, this feat was achieved without sterilizing someone against their will or without the consent of the parents. While there were some legitimate ethical concerns, the underlying purpose has little to do with furthering racial goals and more to do with combating disease and suffering. This is where the difference between eugenics and designer babies at its most stark.

Eugenics, historically speaking, was almost always pursued with a racial agenda. It never stopped at just treating disease. Its advocates sought more than just health. They sought superiority. That’s not how the emerging technology surrounding CRISPR is being used. It’s following a similar path to that of in-vitro fertilization, which was subject to plenty of controversy as well.

Like any technology, there are going to be legitimate concerns mixed in with the doomsayers. With CRISPR and designer babies, the concerns will be greater because the stakes will be higher. We’re not just talking about a technology that will reduce the risk of inherited diseases. This technology could fundamentally change the human race in a very literal sense.

Designer babies, much like their in vitro counterparts, will be part of that change. Regardless of how someone feels about endowing a baby with the genetics of Tom Brady and Stephen Hawking, the potential for good is just too vast. Thousands of people die every year because of diseases that are written into their genes. This technology, if properly refined, could render such suffering a distant memory.

Hesitating with this technology because of potential links to eugenics will only prolong this suffering. In the same way countless individuals wouldn’t be alive without in-vitro fertilization, there are countless people who aren’t alive now because this technology wasn’t available to help them.

Treating diseases and ensuring the health of the next generation is a common good that eugenics corrupted with racist ideology. It attempted to do that by using science and technology to more effectively oppress their chosen enemies. That is radically different than editing the genes of a child so they don’t succumb to certain diseases.

That’s not to say there aren’t risks. At some point, someone will try to abuse this technology and it’s likely that person will have unpopular views on eugenics. There will also be a point where this technology isn’t just used to treat diseases. It will also be used to implement traits and abilities within people that aren’t possible by natural means.

The look of a baby who never has to worry about genetic diseases.

The merits and ethics of such genetic tampering are definitely worth discussing, but references to eugenics will only serve to derail that discussion for all the wrong reasons. Like it or not, humans will need to keep adapting and growing in our chaotic world. If we ever hope to outlast our planet and even our sun, we can’t be bound by genetic constraints or outdated attitudes.

That makes developing genetics technology all the more vital. Eugenics was a bad ideology that hijacked a lot of good science. Whatever your opinion may be on designer babies and improving the human genome, the technology is here. Children born of this technology have arrived. The benefits are vast, provided we have the right approach.

The (Other) Implications Of The Technology In “Jurassic World”


Movies and TV have a long and colorful history of predicting future technology. The predictions made by “The Simpsons,” alone, are as uncanny as they are creepy. Even when they get the basic laws of physics horribly wrong, they can provide insight into the trends that may very well define our future.

On the spectrum of movies that envision future technology, the “Jurassic Park” franchise occupies a strange part of that spectrum. The original movie, as beloved and successful as it is, did a poor job of predicting the potential of genetic engineering. The entire plot of the movie hinged on the ability of scientists to find sufficiently intact DNA from a 65-million-year-old mosquito and use that to recreate dinosaurs.

Anyone with a passing knowledge of math and the half-life of DNA knows that’s just not possible in the real world. No matter how well-preserved a fossil is, the bonds holding DNA together dissolve completely after about 7 million years so the scientists in “Jurassic Park” wouldn’t even have fragments to work with.

That’s not to say it’s impossible to bring back an extinct species. If you have intact DNA, and we do have it for extinct animals like Mammoths, then there’s no reason why science can’t recreate a creature that no longer exists. The only challenge is gestating the animal without a surrogate, but that’s just an engineering challenge that will likely be solved once artificial wombs are perfected.

Even with that advancement, it would be too late for dinosaurs. Technically, if you had enough working knowledge of how DNA works and how to create an animal from scratch, you could create something that looked like a dinosaur. In fact, it’s already a popular fan theory that none of the animals in “Jurassic Park” were actually dinosaurs. It’s one of the few fan theories that might have been confirmed on screen.

Those theories aside, it’s the the technology on display in “Jurassic World” that has far greater implications. By that, I don’t mean it’ll bring back dinosaurs or other extinct species. It may actually do something much more profound.

Unlike the original movies, both “Jurassic World” and the sequel, “Jurassic World: Fallen Kingdom,” don’t stop at just bringing back dinosaurs. These movies take place in a world where that spectacle isn’t that exciting anymore. As a result, they start splicing the DNA of other dinosaurs together to create new species, namely the Indominous Rex and the Indoraptor.

While this creates for great action scenes and plenty of dinosaur-driven combat, the true implications of this technology are lost in the spectacle. Take a moment to consider what the science within these movies accomplished. Then, consider what that means for the real world and the future of the human race.

These dinosaurs were not the product of evolution. Evolution works within some pretty rigid limits. It’s a slow, clunky, arduous process that takes a lot of time and a lot of extinction. On top of that, the basic laws of heredity and the inherent limits of hybridization ensure that the transmission of certain traits are next to impossible through natural means.

However, as Dr. Wu himself stated in “Jurassic World,” there’s nothing natural about what what they did. Essentially, the scientists in that movie used the genetic and evolutionary equivalent of a cheat code. There were no barriers to combining the DNA of a T-Rex with that of a Raptor. They just cut and pasted DNA in the same way you would cut and paste text on a word document.

That should sound somewhat familiar to those who have followed this website because that’s exactly what CRISPR does to some extent. It’s basically the cut function for DNA and it exists in the real world. The paste function exists too, although it’s not quite as refined. To that extent, “Jurassic World” is fairly accurate in terms of the technology they used to create the Indominous Rex and Indoraptor.

That’s not to say it’s possible to create the exact same creatures depicted in the movies. There are various anatomical limits to how big, fast, or smart a creature can be, even if there are no genetic barriers to contend with. I don’t know if the creatures created in “Jurassic World” could function in the real world, but the science for making them does exist, albeit in a limited capacity.

That, in and of itself, is a remarkable notion and one that makes the original “Jurassic Park” seem slightly more incredible. If anything, the original movie underestimated the progress that science would make in genetic engineering. That movie just had science rebuilding life from the remnants of existing creatures. We’ve already progressed to the point where we’re starting to make synthetic life from scratch.

This kind of technology has implications that go far beyond bringing extinct animals back from the dead or creating new ones that make for great fight scenes in a movie. It actually has the potential to circumvent evolution entirely in the struggle for survival. “Jurassic World: Fallen Kingdom” even explores this concept, but only to a point.

Without getting too deep into spoiler territory, this movie builds on the same genetics technology that “Jurassic World” introduced with the Indominous Rex. However, it isn’t just applied to dinosaurs. The sequel dares to contemplate how this technology could be used on humans or to supplement human abilities.

It’s not that radical a concept. Humans have, after all, used technology and breeding techniques to domesticate animals that have aided our efforts to become the dominant species on this planet. That process is still hindered by the hard limits of biology. The process in “Jurassic World: Fallen Kingdom” is not bound by those limits.

In this movie, dinosaurs go beyond a spectacle at a theme park. They suddenly become a potential asset to further augment human abilities. Some, such as Jeff Goldblum’s character, Ian Malcolm, would argue that such creatures pose a risk to humanity’s survival. I doubt I’m as smart as Dr. Malcolm, but I’d also argue that he’s underselling just how dominant human beings are at the moment.

Maybe if dinosaurs had come back 1,000 years ago when humans were still using swords, spears, and arrows to fight animals, we might have had a problem. Today, humans have access to machine guns, tanks, and combat drones. Even the apex predators of the Jurassic don’t stand a chance.

I would further argue that the same technology that the scientists in “Jurassic World: Fallen Kingdom” used to make the Indoraptor is even more valuable in terms of how it can affect humans. After all, if you can copy and paste desirable traits into a dinosaur, then you can do the same to a human.

Doing that might cause plenty of ethical issues that Dr. Malcolm has articulated before, but there’s one factor that overshadows all those arguments and that’s the survival of our species. Let’s face it, the human has its limits. We can’t breathe underwater. Our skin is soft and vulnerable. Our immune system has room for improvement.

There are other mammals out there who can survive extreme cold. There are animals whose immune systems are much more effective than ours. There are even some animals that don’t even age. Nature has already solved many of the problems that hinder the human species today. It’s just a matter of taking those solutions and integrating them into our own biology.

If the technology in “Jurassic World: Fallen Kingdom” can create a creature as advanced as the Indoraptor, then there’s no reason why it can’t also create a human who has the muscle strength of a mountain gorilla, the immune system of an alligator, and the longevity of a tortoise. That kind of application is far more impactful than creating fancy zoo attractions.

I imagine that Dr. Malcolm might still warn about the use of this technology, but it may actually be an even greater risk to not use it. Again, it comes back to survival. Eventually, the Earth is going to die, either by the destruction of our sun or some other external force. If we’re to survive beyond that, we need to be able to survive outside one planet.

As it stands, the human species just isn’t built for that. It shows in how poorly our bodies react to space travel. It also shows in how much we struggle to survive in certain environments. To some extent, we must use the technology in “Jurassic World” to improve our survival.

Whether that involves tweaking our genetics with traits from more robust animals or creating pet raptors that help protect us, this technology has uses that are both profound and necessary. There’s still plenty of danger, although it’s doubtful any of that danger entails someone getting eaten by a T-Rex. However, it’s a danger we’ll have to confront whether the Ian Malcolms of the world like it or not.
