Woolly mammoths could again walk the Earth in just a few years

Colossal lands $15 million to restore the woolly mammoth to the Arctic. The CRIPSR startup 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: bring 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, but instead to bring their cold-adapted genetic traits, which include 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.

There are other ways Colossal hopes to help. Its gene editing technology could artificially add genetic diversity to species with only small surviving populations, Lamm said.

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 protecting 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.

Why You Should Consider a Burner Phone for Your Holiday Travel This Year

If you’re traveling internationally, carrying a simple phone that doesn’t store personal information can be a smart move when entering the US.

Travel is challenging enough, and this year adds a new hurdle. US border agents are stepping up searches of travelers entering the country — even US citizens returning from overseas — and that extends to their personal devices. These searches can go beyond a quick look, giving agents the authority to copy or analyze a phone’s contents.

According to new figures from US Customs and Border Protection, nearly 15,000 device searches were carried out between April and June, with over 1,000 of them using advanced tools that copy or analyze what’s on a phone. The rising numbers raise questions about how much personal data travelers may be handing over without realizing it.

So what’s the solution? A burner phone. It’s the ultimate defense for keeping your personal data private when you travel, ensuring you stay connected without handing over your entire digital life at the border.

But the appeal goes beyond privacy. A stripped-down phone is also the perfect escape from the constant notifications and screen-time vortex of your primary device. Even celebrities such as Conan O’Brien have embraced simpler phones to cut through the noise. Whether you’re crossing a border or just trying to cross the street without distractions, a burner might be the smartest tech you own.

Although carriers have offered prepaid phones since the ’90s, «burner phones» or «burners» became popular in the 2000s following the celebrated HBO series The Wire, where they helped characters avoid getting caught by the police. Although often portrayed in that light, burners aren’t only used by criminals; they’re also used anyone concerned with surveillance or privacy infringement.

What is a burner phone, and how does it work? Here’s everything you need to know about burners and how to get one.

What is a burner phone?

A burner phone is a cheap prepaid phone with no commitments. It comes with a set number of prepaid call minutes, text messages or data, and it’s designed to be disposed of after use.

Burners are contract-free, and you can grab them off the counter. They’re called burner phones because you can «burn» them (trash them) after use, and the phone can’t be traced back to you, which makes them appealing to criminals. Burner phones are typically used when you need a phone quickly, without intentions of long-term use.

Burners are different from getting a regular, contract-bound cellphone plan that requires your information to be on file.

Why should you use a burner phone?

Burner phones are an easy way to avoid cellphone contracts or spam that you get on your primary phone number. Burners aren’t linked to your identity, so you can avoid being tracked down or contacted.

You don’t have to dispose of a burner phone after use. You can add more minutes and continue using it. Burner phones can still function as regular phones, minus the hassle of a contract.

You can also get a burner phone as a secondary phone for a specific purpose, like having a spare phone number for two-factor authentication texts, for business, or to avoid roaming charges while traveling. Burner phones are often used by anyone concerned with privacy.

Burner phones, prepaid phones, smartphones and burner SIMs: What’s the difference?

Burner phones are cheap phones with simple designs that lack the bells and whistles of a smartphone. Because they’re designed to be disposable, you only get the essentials, as seen by the most common version, the flip phone.

All burner phones are prepaid phones, but not all prepaid phones are burners. What sets a burner apart is that you won’t have to give away any personal information to get one, and it won’t be traceable back to you. Again, a burner phone is cheap enough to be destroyed after use.

Prepaid smartphones are generally low-end models. You can use any unlocked smartphone with prepaid SIM cards, essentially making it a prepaid phone.

If you want a burner, you don’t necessarily have to buy a new phone. You can get a burner SIM and use it with an existing phone. Burner SIMs are prepaid SIMs you can get without a contract or giving away personal information.

Where can you buy a burner phone?

Burner phones are available at all major retail outlets, including Best Buy, Target and Walmart. They’re also often available at convenience stores like 7-Eleven, local supermarkets, gas stations and retail phone outlets like Cricket and Metro.

You can get a burner phone with cash, and it should cost between $10 and $50, although it may cost more if you get more minutes and data. If you’re getting a burner phone specifically to avoid having the phone traced back to you, it makes sense to pay with cash instead of a credit card.

If you just want a prepaid secondary phone, you can use a credit card. Just keep in mind that credit cards leave a trail that leads back to you.

There are also many apps that let you get secondary phone numbers, including Google Fi and the Burner app. However, these aren’t burners necessarily because the providers typically have at least some of your personal information.

Chrome Autofill Now Supports Passport, Driver’s License and Vehicle Info

Soon, you’ll never need to remember anything ever again.

Computer users are accustomed to web browsers autofilling everything from names and addresses to credit card numbers. Now, Google Chrome is adding new enhanced autofill options that allow users to automatically populate fields for passports, driver’s licenses, and their vehicle’s license plate or VIN, Google said in a blog post on Monday.

Desktop users must choose to turn on the feature, which is called enhanced autofill. Otherwise, it stays off. To turn it on, open Chrome, and at the top right of your browser, select more, then settings, then autofill and passwords. Finally, choose enhanced autofill and turn it in.

Google says Chrome now can «better understand complex forms and varied formatting requirements, improving accuracy across the web.» The company also says that enhanced autofill will be «private and secure.»

This enhanced autofill update is available in all languages, and more data options will be supported in the coming months.

A representative for Google said the company had no additional comment.

Chrome is a critical component in Google’s business. The web browser, currently the most popular in the world with a 73% market share, according to GlobalStats, provides the company with valuable user data that it uses to sell advertising. Advertising is how Google makes the majority of its revenues. New features help keep users loyal to Chrome, making it more difficult for them to switch to other browsers, including those from companies like Perplexity and OpenAI.
