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.

McDonald’s Snack Wraps Are Back but Was It Worth the Wait?

Review: McDonald’s Chicken Snack Wraps are back and I sampled both varieties on release day. Here’s what I think.

McDonald’s Snack Wraps, a chicken-tortilla entree that’s been missing from US locations of the Golden Arches, flew back into US restaurants on July 10 — and after all this build-up, I had to try both flavor varieties right away.

McDonald’s Snack Wraps first came out in 2006 and were meant to be a chicken item that would appeal to drive-thru customers because they’re less messy to eat while traveling. Both of the two varieties include white-meat chicken strips known as McCrispy Strips wrapped in a flour tortilla with shredded cheese and lettuce. McCrispy Strips are a reworked version of a chicken item formerly known as Chicken Selects.

McDonald’s Ranch Snack Wrap is worth the wait

If there’s a basic or classic version of the two Snack Wrap varieties offered, it’s the Ranch Snack Wrap. It consists of one McCrispy chicken strip wrapped in a flour tortilla, sprinkled with shredded lettuce and shredded cheese, and lightly doused with the chain’s McCrispy Ranch Sauce.

Honestly, I was a little worried that the Ranch Snack Wrap wouldn’t live up to all the hype. Two days before the McDonald’s wraps came out, I tried out the very similar chicken snack wraps at Popeyes Louisiana Kitchen, another fast-food franchise that’s jumped on the snack wrap bandwagon. And they were delicious — but then, chicken is Popeyes’ reason for being. Those wraps were so good, in fact, that I wondered if McDonald’s, not a chicken franchise by nature, could possibly compete.

Good news: The McDonald’s Ranch Snack Wrap is delicious, and just about as good as Popeyes’ version. You’ll notice right away that it’s weirdly designed. The tortilla is huge compared to the relatively small chicken piece, and if you don’t slide the chicken up your first few mouthfuls will be plain tortilla and little else.

But the chicken is fresh and juicy, the cheese and lettuce are decent add-ons and the ranch sauce brings in a creamy taste of herbs and spices that blends well with the chicken. Note that the sauce delivery was kind of hit-or-miss, so you might want to add a shot of your own ranch dressing if you want an even distribution of sauce.

But it’s McDonald’s, not a fancy Michelin-starred eatery, so who expects perfection? If I was eating at McDonald’s, I’d order the Ranch Snack Wrap over either a basic burger or a McChicken sandwich every day of the week.

Grade: A

McDonald’s Spicy Snack Wrap review: Sauce is the weak spot

The Spicy Snack Wrap also features one McCrispy chicken strip inside a flour tortilla, again sprinkled with shredded lettuce and cheese. But this time, the sauce is McDonald’s orangey Spicy Pepper Sauce. And that’s the problem.

I love spice, often adding Sriracha or hot honey to my sandwiches, but I actively disliked the McD Spicy Pepper Sauce. It was overly sweet and dominated each mouthful, so while the chicken itself was the same crispy juicy strip as in the Ranch Snack Wrap, its taste was buried. There’s no question that it comes with a kick, though — I was still feeling the heat 20 minutes after lunch.

If I ordered McDonald’s Snack Wraps again, I’d stick to the Ranch Snack Wraps and pass on the Spicy Snack Wraps. But if you want to try both, I noticed on McDonald’s app that you can order a mix-and-match meal including one Ranch Snack Wrap, one Spicy Snack Wrap, fries and a drink.

Grade: B-

Fans have Snack Wrap fever

Zach Ciampa, who regularly covers new food releases under the social-media handle Snach With Zach, said there’s been an intense fan base out there for the wraps.

«Regarding McDonald’s Snack Wrap, it’s by far the most requested item I’ve ever seen my audience ask or demand to come back,» he told CNET. «Not just the most requested in recent memory but the most requested of all time. And that’s not limited to McDonald’s.»

Ciampa said the only similar fast-food items that come close to the same level of interest are Dairy Queen’s S’mores Blizzard and Taco Bell’s Caramel Apple Empanada, both of which have made recent returns.

McDonald’s is riding a viral wave. The fast-food chain’s Minecraft Happy Meals and adult Minecraft Meals hit restaurants on April 1 and sold out quickly.

A recent analysis by VegasInsider.com found that the Snack Wrap was by far the most searched for discontinued McDonald’s menu item of 2025.

What you need to know about Snack Wraps

Release date and time: The Snack Wraps are at participating McDonald’s now. You can order on the McDonald’s app, in restaurants, or in drive-thrus.

Price: At my local restaurant, Snack Wraps are priced at $3 apiece and a meal including fries and a drink was listed at $12. Prices may vary by location, A co-worker said Snack Wrap meals were $10.50 at his New York City McDonald’s.

Varieties: You can order a Snack Wrap in Spicy, which features a habanero-pepper kick, or Ranch, which features a burst of cool ranch sauce.

Here’s the Mystery Flavor of McDonald’s New Pink and Blue Shake

The crazy-colorful shake is part of the McDonaldland Meal, which is like a (pricey) Happy Meal for adults. And now I know the flavor.

I tried the McDonaldland Meal at my local McD’s on Aug. 12, the day it came out. And I don’t want to say that I’ve been thinking about the mystery flavor of its pink-and-blue Mt. McDonaldland shake ever since, because that would make me sound truly bizarre, but…I have pondered it.

When I tasted the shake, I guessed it was maybe blue raspberry, maybe cotton candy, maybe mixed berry. It’s sweet but not sickeningly so, though I’d never order it again. (I’m a chocolate fan.)

But I kind of wanted to know what the mystery flavor was. And now I do: According to McDonald’s Canada’s own nutrition page for the shake, the blue beauty features a «mix of creamy vanilla soft serve and raspberry flavored syrup.» (I tried to confirm this on the US nutrition page, but it just spun and spun and never loaded. Get on that, Ronald.)

RASPBERRY! The Mt. McDonaldland shake is raspberry flavor! And it’s blue in color, so my guess of blue raspberry was correct! Raspberry is the hot fast-food flavor these days, as Starbucks just brought back its much-loved raspberry drink syrup in late July.

If you’re wondering what I’m even talking about, McDonald’s continues to capitalize on the love of its customers for the company’s goofy history. Recently, Happy Meals included McDonald’s-themed toys — such as drink machines, fryers and trays with food on them — delivered in mini-Happy Meal boxes. And the much-longed-for Snack Wraps finally returned after a viral fan campaign.

The McDonaldland Meal goes straight after that market of adults who have a nostalgic feeling for the Golden Arches. It’s not cheap — here in high-cost-of-living Seattle, the medium meal was $16.59 and the large was $18.29.

You can choose from a Quarter Pounder with cheese or a 10-piece McNugget order. It also comes with the chain’s famous french fries and your choice of drink. But the specialty drink that’s made to go with the meal is called that mystery-until-now-flavored Mt. McDonaldland shake, and it’s a blazing blue color, topped with hot pink whipped cream. It’s supposed to look like a volcano, with the pink cream as lava, I guess.

You can order the shake without the meal if you just want to try it. If you don’t want to try it, you can choose a regular drink or another flavor of shake with your McDonaldland meal.

I sampled the hot pink whipped cream by itself, and it seemed to have no flavor, so maybe they just took regular whipped cream and dyed it pink.

Instead of a simple toy, the McDonaldland Meal comes with a 5-by-7-inch tin with one of the McDonaldland mascot characters on it. I ended up with Hamburglar, who, after Grimace, would probably have been my choice.

Tins come embossed with Hamburglar, Grimace, Ronald McDonald, Mayor McCheese, Birdie the Early Bird and the Fry Guys. Honestly, I’m not sure what anyone would do with this tin, but it was definitely a classier included item than most of the Happy Meal toys.

Inside the tin is a card with a code you can scan to explore McDonaldland online, an ID card for your particular character, two postcards and four stickers. One of my stickers said «robble robble,» the Hamburglar’s favorite saying, and one read, «Keep up! Hamburglar and I are mid-heist.» I can’t really imagine anyone putting these on their water bottle or laptop, but to each their own.

Honestly, unless McDonald’s nostalgia is your thing, I’d recommend you just stick to ordering your usual at the Golden Arches and skipping the meal. But if you just don’t get enough blue and pink food in your life — and who does? — try the Mt. McDonaldland shake once, pass it around to let your friends make them guess the flavor before you smugly deliver the big reveal, and then go back to chocolate or another good old standard flavor.

A $101 Discount Means This PlayStation VR 2 Bundle Has Never Been Cheaper

Grab a top-rated VR headset and one of its best games for just $299 with this incredible remaining Cyber Monday bargain.

Listing at $299, the Meta Quest 3S is the most affordable way to dip your toes into the world of VR. But for high-end console gaming, the PlayStation VR 2 is the way to go. It’s a little pricier than the competition at $400, but this remaining Cyber Monday deal drops it down to a new record low.

Both Amazon and Walmart have the Horizon Call of the Mountain bundle on sale for just $299 right now. That means you’ll save $101 on the headset and also get one of the best PSVR 2 games for free. We don’t expect this deal to last for long since most sales have ended, though, so be sure to take advantage of these savings while you still can.

It’s important to note that you’ll also need a PS5 console to use the PSVR 2 headset, but thankfully they are also on sale right now. You can grab the digital-only PS5 Slim for just $400, which is $100 off the usual price.

The PSVR 2 features heightened Sense technology with eye tracking, 3D audio, haptic feedback, adaptive triggers and touch detection. Its enhanced eye tracking and haptics set it apart from the Quest headset, though the Meta system can be standalone and is more versatile.

Sony has not been amazing at supporting its PSVR 2 headset with first-party titles, but there are plenty of third-party games to play. Additionally, you can pick up an adapter to use it on a PC. All in all, it makes for a great gift this holiday season. And for $299, this is a sizable drop in price compared to when it launched.

Why this deal matters

Because you need both a PS5 console and the headset, investing in a PSVR 2 can be pretty pricey. But if you are looking to grab one, now is the time to do so. Not only is this the all-time lowest price we’ve seen on the Horizon Call of the Mountain bundle, but now you also have a rare chance to grab a PS5 console on sale.
