X Is Retiring Twitter.com. Update Your Account Now or Risk Lockout

The official retirement of the old domain is the next step in Elon Musk’s rebranding of the social media platform.

RIP Twitter.

X, the platform formerly known as Twitter, will retire its old domain. This comes with a warning for you: If you don’t update your account’s security settings soon, you could be locked out.

The shift marks another step in Elon Musk’s ongoing rebrand of the social network over the last two years. Musk, who bought Twitter in October 2022 and later renamed it X, has made sweeping changes to the platform’s features and policies.

The company notified users that anyone using hardware security keys or passkeys tied to twitter.com must reenroll them under the new x.com domain. The deadline is Nov. 10. After that date, affected accounts may be temporarily locked until the update is completed.

By November 10, we’re asking all accounts that use a security key as their two factor authentication (2FA) method to re-enroll their key to continue accessing X. You can re-enroll your existing security key, or enroll a new one.
A reminder: if you enroll a new security key, any…

X emphasized that the move isn’t related to a data breach or security issue but is a necessary step in the platform’s domain transition, marking the end of Twitter’s last remnants.

«This change is not related to any security concern, and only impacts Yubikeys and passkeys, not other 2FA methods (such as authenticator apps),» the company’s Safety account stated on X. Because security keys enrolled as a two-factor authentication method are currently tied to the former domain, reenrolling your security key will associate them with the new domain.

For most users, the change will go unnoticed. But if you rely on physical security keys, such as YubiKeys, or use passkeys for password-less login, you could be caught off guard if you don’t take action before the cutoff date.

Update your saved credentials. Make sure your logins now point to x.com instead of twitter.com.

A Historic Heat Dome Is Creeping Across the US. Here’s How to Prepare

After breaking heat records in 14 states, the heat wave pummeling the Southwest is moving eastward.

A massive heat wave has broken heat records in 14 states, including Arizona and California, reaching up to 112 degrees Fahrenheit in some areas. Now it’s creeping eastward, according to the National Weather Service.

The heat wave is continuing its journey through the Midwestern United States and is projected to affect anywhere from one-quarter to one-third of the 48 mainland states, National Weather Service meteorologist Gregg Gallina told The Associated Press. The highest temperatures recorded today are in Arizona, New Mexico and Texas — what the National Weather Service refers to as the Southern Rockies region. But the hot air is on the move.

The reason these high temperatures persist is the «heat dome» phenomenon, in which high pressure prevents hot air from rising, trapping it in a bubble above a region. As the dome of pressure moves, so too does the hot air — and right now, it’s barreling east.

The states that will be smothered by the heat dome in the coming days include those in the Southern and Central Plains regions. This means residents of Texas, Colorado, Oklahoma, Kansas and Nebraska can expect to sweat as the heat blankets them on its eastbound journey.

What the heat dome means for climate change and our health

According to Climate Central, the US has experienced rising blackout rates over the past 20 years, largely due to weather-related issues and an aging electrical grid.

As of August 2025, the US Environmental Protection Agency states that heat is the leading weather-related cause of death in the US. The World Health Organization reports that between 2000 and 2019, about 489,000 heat-related deaths occurred each year.

Fortunately, humidity levels are not as high during a summer heat wave. As humidity can contribute to dehydration, body strain and breathing difficulties, lower humidity makes this heat dome somewhat less dangerous for workers in affected areas.

The World Weather Attribution, an initiative formed by international climate change researchers and climate scientists, determined that the heat dome would be «virtually impossible without human-induced climate change.»

In a world where weather events like these cease to be impossibilities, you’ll want to prepare for future heat waves properly. Here’s how to stay safe during the heat dome.

How to prepare for the heat dome before it hits your state

There’s nothing you can do to beat the heat outside, aside from following heat safety best practices. You’ll just need to stay hydrated, wear breathable, light-colored clothing and wait out the potentially dangerous heat dome, which is expected to dissipate by the end of next week when April begins. But you can do things to batten down the hatches before the sweltering heat reaches your home.

Even if you don’t have much prep time, a couple of small items can make your home safer (and far more comfortable). Cooling towels, portable fans and countertop ice makers are must-haves during a heat wave, especially if you aren’t looking to crank the thermostat down and spend a pretty penny.

Heat waves are also extremely costly due to the sheer amount of energy used — it’s expensive to stay cool. Depending on your living situation, though, you might want to invest in heat pump installation. These HVAC system additions are extremely energy efficient, which means you can keep more money in your pocket while beating the heat.

During the middle of the heat wave, when everyone has their AC running, there’s also the potential for an early brownout (a temporary drop in electrical voltage, causing lighting to dim) or even a blackout (a complete loss of power). It’s common to feel helpless during power outages, but you can get ahead of the curve by preparing a summer blackout kit with portable chargers and alternative light sources before the heat wave hits.

Even if the historic heat wave doesn’t hit your home, these tips will help you prepare as the summer season bears down on the US in a couple of months.

Apple May Give Siri a Big AI Overhaul in iOS 27

Apple is testing a standalone Siri app, a new interface and deeper AI features for this year’s software update, Bloomberg reports.

Apple may be planning one of the biggest changes to Siri since the voice assistant launched more than a decade ago. According to a report on Tuesday from Bloomberg, Apple is testing a standalone Siri app, a redesigned interface and a new «Ask Siri» button that would make the assistant more visible and useful across the Apple ecosystem, as part of a broader AI reboot.

According to the Bloomberg report, the new Siri experience is expected to be introduced at Apple’s Worldwide Developers Conference on June 8 and would arrive as part of iOS 27, iPadOS 27 and MacOS 27 later this year. The report says Apple is testing out a new Siri that would make the assistant feel more like a standalone AI chatbot — think ChatGPT or Claude — rather than the current built-in tool.

The latest report builds on earlier Bloomberg reporting from January, which said Apple planned to revamp Siri into its first real AI chatbot to better compete with OpenAI and Google.

For Apple, the move would mark another attempt to reset expectations around its AI strategy after repeated delays to its more advanced Siri ambitions. Apple had previewed a more personalized Siri at WWDC 2024, but the broader rollout has slipped, and Bloomberg’s new report suggests the company is now aiming for a more sweeping relaunch in iOS 27 instead.

Apple has not publicly announced these iOS 27 features, so plans could still change before WWDC.

An Apple representative didn’t immediately respond to a request for comment.
