Scientists map 17,000-year-old woolly mammoth’s path using its tusk

One ancient male mammoth was quite the vagabond.

We might think of woolly mammoths as giant, lumbering beasts from a disappeared era, but a new study suggests their massive size didn’t stop them from tallying major miles in the frigid north thousands of years ago.

«It’s not clear cut if it was a seasonal migrator, but it coveredsome serious ground,» explains University of Alaska Fairbanks researcherMatthew Wooller, in a statement. «It visitedmany parts of Alaska at some point during its lifetime, which is prettyamazing when you think about how big that area is.»

Wooller led a team using chemical isotope data to map the life journey of a single mammoth that lived over 17,000 years ago. A paper on the findings is the cover story in this week’s issue of the journal Science.

The group of international researchers analyzed isotopic signatures in the male mammoth’s tusk from the elements strontium and oxygen, then cross-referenced that data with maps of isotope variation across Alaska created from analyzing the teeth of small rodents from around the state.

«From the moment they’re born until the day they die, they’ve got adiary and it’s written in their tusks,» said Pat Druckenmiller, apaleontologist and director of the University of Alaska Museum of the North. «MotherNature doesn’t usually offer up such convenient and life-long records ofan individual’s life.»

The ancient dental records show the big old boy lived to be 28 years old and in that time it covered enough of the Alaskan tundra, taiga and mountains to nearly circle the world twice.

This woolly one didn’t exactly have an easy journey, though. The analysis showed an abrupt shift around age 15 that likely means the mammoth was ostracized from its herd, which often happens with contemporary elephants. Later, a spike in nitrogen isotopes during the last winter of the animal’s life suggest it may have starved to death where its remains were eventually recovered above the Brooks Range.

That fate was a sad harbinger for the entire species. The individual mammoth was related to the last group that roamed mainland Alaska, likely outlasted by only a few small groups on northern islands.

The research also has a darkly relevant feel today for extant species in the north like polar bear that are seeing their traditional range dwindle as the Arctic takes on the brunt of global warming.

«The Arctic is seeing a lot of changes now, and we can use the pastto see how the future may play out for species today and in the future,»Wooller said. «Trying to solve this detective story is an example ofhow our planet and ecosystems react in the face of environmentalchange.»

Skip Your iPhone’s Lockscreen: Here’s the Hidden Flashlight Trick You Need to Know

A couple of taps can really make a difference on your iPhone.

Not long ago, your iPhone’s lockscreen would only allow two app shortcuts that you couldn’t change: camera controls and a flashlight toggle. However, iOS 18.2 allows you to customize these shortcuts to almost anything you might want. This small but impactful change is one of many ways iOS 18 supercharges customization for iPhone and iPad users. But what if you still want an easy-to-access way to toggle your flashlight without unlocking your phone?

Apple introduced an accessibility feature in iOS 14 that, once enabled, allows you to perform actions by just tapping on the back of your phone. The feature is called Tap Back and it remains a sleeper feature that’s sneakily hidden away in your settings menu. Enabling Tap Back essentially allows you to create a button on the back of your iPhone to perform an action without needing to take up any space.

Once you have Tap Back enabled, it doesn’t take long to see how much of a game-changer it can be with its added convenience. Below, we’ll show you how to set it up so a couple of taps on the back of your iPhone will let you launch just about anything you want.

For more, check out what’s in the latest iOS 18.4 release.

How to set up Back Tap on iPhone

Whether you want to link Back Tap with your flashlight, camera or launch a different iPhone app, the path through your iPhone settings begins the same way.

On your compatible iPhone (iPhone 8 or later), launch the Settings application and go to Accessibility > Touch > Back Tap. Now you have the option to launch your action (in this case, your flashlight) with either two or three taps. Although two taps is obviously faster, I would suggest three taps because if you fidget with your phone, it’s easy to accidentally trigger the accessibility feature.

Once you choose a tap option, select the Flashlight option — or a different action if you prefer. You’ll see over 30 options to choose from, including system options like Siri or taking a screenshot, to accessibility-specific functions like opening a magnifier or turning on real-time live captions. You can also set up Back Tap to open the Control Center, go back home, mute your audio, turn the volume up and down and run any shortcuts you’ve downloaded or created.

You’ll know you’ve successfully selected your choice when a blue checkmark appears to the right of the action. You could actually set up two shortcuts this way — one that’s triggered by two taps and one that’s triggered by three taps to the iPhone’s back cover.

Once you exit the Settings application, you can try out the newly enabled Back Tap feature by tapping the back of your iPhone — in my case, to turn on the flashlight. To turn off the flashlight, you can tap on the back of your iPhone as well, but you can also just turn it off from your lock screen if that’s easier.

For more great iPhone tips, here’s how to keep your iPhone screen from dimming all the time and canceling all those subscriptions you don’t want or need.

All the Nintendo Games You Can Update to Switch 2 for Free

Bad news: Mario Kart World will cost $80. Good news: These classic games will get free revamped versions for Switch 2.

Nintendo’s Switch 2 launch event on Wednesday has upset some fans for one key reason: pricing. The new console will be released on June 5 at a starting price of $450, and it will have new games, like Mario Kart World, Kirby Air Riders and Donkey Kong Bananza. But those games could cost as much as $80 (and that’s before factoring in possible tariffs).

Fortunately, Nintendo has also announced that some Nintendo Switch games will get free updates to improve playability on the upcoming console.

«By connecting your Nintendo Switch 2 to the internet, you can download free updates that may improve performance or add support for features such as GameShare in select games,» the company posted.

Here are all the Nintendo Switch games that can get a free update for the Switch 2.

Nintendo also announced that other Switch games will have upgraded versions of the base game, called Switch 2 Editions. These games, which include The Legend of Zelda: Breath of the Wild and Tears of the Kingdom, may offer improved graphics, unique ways to play the game with the Switch 2 hardware, and other features.

You can buy a digital or physical copy of these games if you’re purchasing them for the first time. But Switch 2 Edition games are not free if you already own the Switch version of one of these games, so you’ll have to buy an upgrade pack to play the updated version.

It’s unclear how much Switch 2 Editions of games and upgrade packs will cost, and it’s also unclear how upgrade packs will work with physical versions of Switch games.

The Nintendo Switch 2 will also be backward compatible with certain games. While we don’t know all the Switch games that will be playable on the Switch 2, we know some Switch games have startup (PDF) or in-game (PDF) compatibility issues with the upcoming console.

For more on the Nintendo Switch 2 Direct, here’s what we know about the upcoming console and what to know about games like Mario Kart World and Duskbloods.
