CRISPR startup wants to resurrect the woolly mammoth by 2027

Colossal has landed $15m in funding to restore the woolly mammoth to the Arctic — and it thinks it can birth calves in four to six years.

You’ve heard of startups building computer chips, delivery drones and social networks. One called Colossal has a very different goal: bringing the woolly mammoth back from extinction by 2027 using CRISPR, a revolutionary gene editing technology.

The plan isn’t to re-create true woolly mammoths exactly but rather to bring their cold-adapted genetic traits like small ears and more body fat to their elephant cousins, creating a hybrid that can wander the tundra where mammoths haven’t been seen for 10,000 years. Colossal’s co-founders are Chief Executive Ben Lamm, who started five companies before this, and George Church, a Harvard Medical School professor with deep CRISPR expertise.

«Our true North Star is a successful restoration of the woolly mammoth, but also its successful rewilding into interbreeding herds in the Arctic,» Lamm said. «We’re now focusing on having our first calves in the next four to six years.»

It’s an interesting illustration of an imperative sweeping the tech world: Don’t just make money, help the planet too. Tesla’s mission is to electrify transport to get rid of fossil fuels that hurt Earth. Bolt Threads wants to replace leather with a fungal fiber-based equivalent that’s easier on the environment than animal agriculture. Colossal hopes its work will draw attention to biodiversity problems and ultimately help fix them.

Colossal has raised $15 million so far, led by investment firm Tulco. The startup’s 19 employees work at its Dallas headquarters and in offices in Boston and Austin, Texas, and it’s using its funds to hire more.

Artificial wombs and other technology spinoffs

Church said he expects spinoffs from the company’s biotechnology and genetics work.

«The pipeline of large scale genome engineering techniques can be applied to many other applications beyond de-extinction, and therefore [are] most promising for commercialization,» he said.

One technology ripe for commercialization is multiplex genome engineering, a technique Church helped develop that speeds genetic editing by making multiple changes to DNA at once.

Colossal also hopes to develop artificial wombs to grow its mammoth embryos. Just growing 10 woolly mammoths with surrogate elephant mothers isn’t enough to get to the large-scale herds the company envisions.

At the foundation of Colossal’s work is CRISPR. This technology, adapted from a method bacteria evolved to identify attacking viruses and chop up their DNA, is now a mainstay of genetic engineering, and Church has been involved since CRISPR’s earliest days.

Jurassic Park-style tourism? Nope

Selling or licensing spinoff technology is a somewhat indirect way of running a business. A more direct option is selling tickets to tourists. After all, humans already pay lots of money to see charismatic megafauna like lions, elephants and giraffes on African safaris. Seeing a creature that’s been gone for 10,000 years could add to the excitement.

But that’s not Colossal’s game plan. «Our focus is on species preservation and protection of biodiversity right now, not in putting them in zoos,» Lamm said. By re-creating woolly mammoths, Colossal can preserve the genetic legacy of Asian elephants that now are endangered.

Another candidate species Colossal wants to re-create is the woolly rhinoceros, a relative to the critically endangered Sumatran rhino.

Although Colossal doesn’t plan to build a tourist destination, it does have a woolly mammoth rewilding site in mind that sounds awfully close to Jurassic Park: Pleistocene Park. This area of about 60 square miles in northern Russia, named after the geologic period that ended with the last ice age, is where researchers Sergey and Nikita Zimov are trying to test their theories about the ecological and climatic effects of rewilding.

One Zimov idea is that woolly mammoths will trample snow and knock down trees. That, in turn, will restore grasslands that reflect more of the sun’s warming rays and eliminate insulating snow and forests so the ground cools more. And that means the ground will stay frozen instead of releasing its current store of carbon dioxide and methane greenhouse gases. About 260 billion to 300 billion metric tons of carbon could be released from thawing permafrost by 2300, scientists calculate, exacerbating the weather extremes and other problems caused by climate change.

Is species de-extinction a good idea?

There’s an appeal to the idea of de-extinction. Humans have dramatically altered the planet, and the United Nations estimates we threaten 1 million species with extinction as a result.

Colossal hopes its work will raise more attention to the biodiversity collapse. And it also plans to create detailed genetic descriptions of many endangered species «so we have the recipe if that species does go extinct,» Lamm said.

But is that really the best use of our resources to help the planet? No, some researchers believe.

Resurrecting species could have some benefits, but money would be better spent on trying to protect ones that are still around, a group of biologists argued in one paper published in Nature Ecology & Evolution. «Potential sacrifices in conservation of extant species should be a crucial consideration in deciding whether to invest in de-extinction or focus our efforts on extant species,» the researchers wrote.

But this isn’t government money Colossal is talking about, and Lamm argues that his startup’s work complements other conservation efforts. And, he argues, startups can move faster than government-funded work.

In a world dominated by climate crisis headlines, a startup that makes money with an ecosystem-improvement focus has special appeal. One investor, Zack Lynch of Jazz Venture Partners, is excited by software, hardware and biotech he expects Colossal will create.

At the same time, «these breakthroughs will help address issues such as land degradation, animal pollinator loss and other negative biodiversity trends,» Lynch said. Given how big our environmental problems are, you can see why an investor might be interested.

Roblox Rolls Out Age-Verification Requirement for Chat Amid Child Safety Criticism

The age-verification tool estimates a player’s age to put them into a specific group before they can chat online.

Roblox, the online gaming platform that has been under fire due to child safety concerns, has introduced age-verification software that uses facial scanning to estimate the age of players.

The system is currently voluntary, but by the first week of December it will be a requirement in Australia, the Netherlands and New Zealand in order for players to chat with others online. By early January, players in all Roblox markets, including the US, will be required to use the software if they want to engage in chats with other players. Roblox said it has also launched a Safety Center hub with information for parents and parental control tools.

Roblox says the age-verification system is being put in place to limit contact between adults and children, which has been a chief concern among child-safety advocates.

However, while some experts expressed optimism about Roblox’s changes, they disagreed on whether the new features go far enough for the platform and whether Roblox’s reputation can be repaired.

How it works

Roblox’s new age-verification feature takes a 3D scan of a player’s face, using a webcam or a mobile device’s camera, to estimate the person’s age. Based on that estimate, a player can use online chat with other players in their age group.

In a video about the software, Roblox says it immediately deletes captured images or video after the age check is complete.

The age check is performed by a vendor of Roblox called Persona.

Once they complete the check, players are grouped into the following age categories: under 9, 9–12, 13–15, 16–17, 18–20, or 21 and over. The company said that those under 9 won’t be allowed to chat without parental permission. The chats won’t be strictly limited to those age groups, necessarily. Roblox said players «can chat only with peers in their group or similar groups, as appropriate.»

A representative for Roblox said in an email to CNET that the technology should not be considered facial recognition because it’s not being used to identify a particularly person, only to estimate their age.

The company said it’s also taking measures such as restricting media sharing among players and using AI to monitor chats.

Ongoing controversy

One of the aims of the launch, which was first announced in the summer, was to address criticism that the platform has not adequately protected underage Roblox players. The criticism comes at a time when Roblox is more popular than ever, having broken its own records this year for the number of players on its platform at the same time. It’s estimated to have about 380 million active monthly users.

Roblox is currently facing dozens of lawsuits related to claims of sexual abuse and child exploitation from families of children who played Roblox. It is also the target of investigations or lawsuits from states including Florida, Texas, Louisiana and Kentucky.

Roblox was dealt a setback earlier this month when a California judge declined the company’s motion to move one of these suits into private resolution.

The company says its safety features are moving beyond what other game platforms offer to protect minors.

According to a corporate post about the safety features: «Roblox is the first online gaming or communication platform to require facial age checks to access chat, establishing what we believe will become a new industry standard.»

The online streaming platform Twitch is also introducing an age scan feature, but so far only in England.
In response to the Roblox and Twitch changes, Anna Lucas, online safety supervision director at the British regulatory agency Ofcom, said, «We’re pleased that children will be better protected from harmful material and predators on Twitch and Roblox. Under the UK’s online safety laws, platforms must now take steps to keep kids safe, and we’re ensuring they meet their responsibilities. There’s more to do, but change is happening.»

What’s next for Roblox?

Experts CNET spoke with in areas including child privacy and safety, online marketing and tech viewed the steps Roblox is taking as positive, But there’s wide disagreement on whether the company is going far enough with its protections.

«Roblox’s new age-verification tools are encouraging, but from a parenting standpoint, they’re just one part of the safety puzzle,» said Dr. Scott Kollins, a clinical psychologist and chief medical officer at Aura, an online safety app. «The real question for families is whether these features meaningfully improve kids’ day-to-day experience on the platform. Age verification is a step forward, but children still need guardrails and clear explanations about how online interactions work.»

Kollins said that active parenting needs to take place before kids log on to Roblox in addition to the company designing its product with safety in mind.

Stephen Balkam, founder and CEO of the Family Online Safety Institute, called the age-verification «a hugely important step» in the direction of making Roblox a safer platform. He said he hoped other online platforms might follow Roblox.

«My only hope is that in the long term, Roblox’s age assurance methods become interoperable with other gaming and kid-focused sites and platforms, so parents and kids only have to go through the verification process once,» Balkam said.

Like Kollins, Balkam emphasized the importance of parental involvement, since no site is entirely safe.

«Set family rules, use parental controls and have regular conversations with your kids,» he said. «So, no, don’t ban Roblox, but use their industry-leading tools and keep the lines of communication open and your kids should be able to have a fun and creative time.»

Liability and trust

Some experts also view the changes as a way to mitigate the company’s reputational damage and address legal challenges.

The age verification is «not a silver bullet,» said Paromita Pain, associate professor of media studies at the University of Nevada, Reno.

«Even a very strong safety revamp doesn’t erase that record, but it does give Roblox a narrative: ‘We heard you, we’re now at or above industry standard, so future risk is sharply reduced,’ » Pain said.

The moves, Pain said, could rebuild trust, but many parents will see age checks as coming too late. Pain said that the company should adopt independent audits of child-safety practices, make its parental and teen controls stricter by default and commit to «safety by design» by making systemwide changes on private servers and environment designs.

The current changes won’t fix things for Roblox, she said. «Only sustained, independently-verifiable changes—and probably some large settlements—will do that.»
