Astronomers Say There’s an Increased Possibility of Life on This Distant Planet

Using the James Webb Space Telescope, astronomers are working to confirm potential evidence of life on a distant exoplanet dubbed K2-18b.

Astronomers are nearing a statistically significant finding that could confirm the potential signs of life detected on the distant exoplanet K2-18b are no accident.

The team of astronomers, led by the University of Cambridge, used data from the James Webb Space Telescope (which has only been in use since the end of 2021) to detect chemical traces of dimethyl sulfide (DMS) and/or dimethyl disulfide (DMDS), which they say can only be produced by life such as phytoplankton in the sea.

According to the university, «the results are the strongest evidence yet that life may exist on a planet outside our solar system.»

The findings were published this week in the Astrophysical Journal Letters and point to the possibility of an ocean on this planet’s surface, which scientists have been hoping to discover for years. In the abstract for the paper, the team says, «The possibility of hycean worlds, with planet-wide oceans and H2-rich atmospheres, significantly expands and accelerates the search for habitable environments elsewhere.»

Not everyone agrees, however, that what the team found proves there’s life on the exoplanet.

Science writer and OpenMind Magazine founder Corey S. Powell posted about the findings on Bluesky, writing, «The potential discovery of alien life is so enticing that it drags even reputable outlets into running naive or outright misleading stories.» He added, «Here we go again with planet K2-18b.Um….there’s strong evidence of non-biological sources of the molecule DMS.»

K2-18b is 124 light-years away and much larger than Earth (more than eight times our mass), but smaller than Neptune. The search for signs of even basic life on a planet like this increases the chances that there are more planets like Earth that may be inhabitable, with temperatures and atmospheres that could sustain human-like lifeforms. The team behind the paper hopes that more study with the James Webb Space Telescope will help confirm their initial findings.

More research to do on finding life on K2-18b

The exoplanet K2-18b is not the only place where scientists are exploring the possibility of life, and this research is still an early step in the process, said Christopher Glein, a geochemist, planetary researcher and lead scientist at San Antonio’s Southwest Research Institute. Excitement over the significance of the research, he said, should be tempered.

«We need to be careful here,» Glein said. «It appears that there is something in the data that can’t be explained, and DMS/DMDS can provide an explanation. But this detection is stretching the limits of JWST’s capabilities.»

Glein added, «Further work is needed to test whether these molecules are actually present. We also need complementary research assessing the abiotic background on K2-18b and similar planets. That is, the chemistry that can occur in the absence of life in this potentially exotic environment. We might be seeing evidence of some cool chemistry rather than life.»

The TRAPPIST-1 planets, he said, are being researched as potentially habitable, as is LHS 1140b, which he said «is another astrobiologically significant exoplanet, which might be a massive ocean world.»

As for K2-18b, Glein said many more tests need to be performed before there’s consensus on life existing on it.

«Finding evidence of life is like prosecuting a case in the courtroom,» Glein said. «Multiple independent lines of evidence are needed to convince the jury, in this case the worldwide scientific community.» He added, «If this finding holds up, then that’s Step 1.»

Little Caesars Wants ChatGPT to Order Your Pizza for You

You can personalize your pie and place your order without leaving the chatbot.

When it comes to building the perfect pizza, you need perfectly structured crust, quality cheese, well-seasoned sauce and fresh, delicious toppings. Oh, and artificial intelligence, naturally.

Or at least that’s what Little Caesars is saying.

Starting today, you can order Little Caesars through a new app inside ChatGPT. OpenAI’s chatbot can customize and order pizzas, or you can use ChatGPT to receive recommendations based on your budget, preferences, dietary restrictions or the number of people you need to serve.

«Today’s consumers are turning to Gen AI as part of how they search for everything, including where to get their next meal,» Greg Hamilton, chief marketing officer at Little Caesars, said in a statement. «We recognize this shift and want to meet our customers where they already are and be the go-to for their pizza occasions. The process is as natural and intuitive as having a conversation. It’s not just about technology for technology’s sake — it’s about making life a little easier for people who love great pizza.»

How ordering a pizza with ChatGPT works

To get started, you’ll need to launch ChatGPT on your desktop or mobile device. On the ChatGPT interface, go to the Apps menu and select Little Caesars. You will need to connect your accounts by signing into your Little Caesars account or creating one. From there, you can get started with ordering.

You can simply type in something like, «Pizzas for five people with no meat,» and you’ll get personalized recommendations for pizzas and sides that match your preferences. From there, you can tailor your order further by swapping toppings, adjusting amounts or adding an order of cookie dough brownies.

Once you review your order, you can checkout through the Little Caesars app and then your order will go to the nearest location for you to pick up when ready. You can also schedule an order ahead of time and track your order in real-time through the app.

The new ordering function is now available across all Little Caesars locations in the US, and many locations in Mexico and Canada.

Not interested in using AI? The Little Caesars app and website are still available, or you can always pick up the phone and call.

Don’t Lose Your Texts: How to Move Away From Samsung Messages Before It Shuts Down

Samsung is deactivating its long-standing Messages app in July. Here’s what to do next.

Samsung is closing the book on its proprietary texting platform this summer. After years of slowly phasing out the software in favor of a more unified experience, the company is finally pulling the plug on its Messages app this July. While many Galaxy owners have already been using Google’s version for years, those holding onto the legacy interface now have a firm deadline to migrate their conversations before the service goes dark.

On a page with information about the switch, Samsung points to instructions on how to swap over to Google’s Messages app, including for phones that are still on Android 12 and Android 13. Samsung has historically preinstalled its own Messages app on Galaxy phones, but began transitioning toward Google Messages as early as 2021.

To encourage people to switch to Google Messages, Samsung’s instructions list new features offered by Google Messages, like RCS-enabled texting for features like typing indicators, easier group chats and sending higher-quality images. Google’s Messages app also has AI-powered spam detection and spam filters, multi-device access to messages and some built-in Gemini AI features. It’s also the app that most Android phones use as their default texting app, including Samsung’s more recent Galaxy S26. There are other SMS texting app alternatives in the Google Play Store if you don’t want to use the one made by Google.

Samsung has not said when exactly in July messaging will no longer work in the app. A Samsung representative didn’t immediately respond to a request for comment. Once the app is deactivated, only messaging to emergency services will work on Samsung Messages.

While Samsung did stop including it as the default texting app in 2021, it wasn’t until 2024 that Samsung stopped preinstalling the texting app alongside Google Messages. The Galaxy S26 can’t download the Samsung Messages app, and other phones won’t be able to download it after the app’s July sunset.

Samsung said users of Android 11 or lower aren’t affected by the end of service, but would also likely benefit from switching to a supported texting app like Google Messages. To switch to Google Messages, the company asks users to download the app if it’s not already installed and to set it as the default SMS app when prompted after launching it.

The post also notes that anyone using an older Galaxy Watch that runs on Samsung’s Tizen operating system will no longer have access to their full conversation history since these watches cannot use Google Messages. Samsung said that they will still be able to read and send text messages, but the company’s newer watches (Galaxy Watch 4 and later) that run WearOS will still have access to full conversations.

New AT&T Elite 2.0 Phone Plan Boosts Wireless Hotspot and Data Performance

For customers willing to pay for it, the new top plan offers more high-speed data and performance than the former one.

Only a few weeks after overhauling its unlimited phone plans, AT&T has added a new plan to the top of the lineup that offers more data and performance — for a higher price. The AT&T Elite 2.0 plan is available now.

For a single line, Elite 2.0 costs $110 (plus taxes and fees). As more lines are added, the per-line price goes down. AT&T customers can mix and match plans on an account, but if we assume everyone is signing up for the Elite 2.0 plan, the costs break down like this:

• One line: $110
• Two lines: $100 per line, $200 total
• Three lines: $85 per line, $255 total
• Four lines: $75 per line, $300 total
• Five lines: $75 per line, $375 total

To compare it with AT&T’s next-priciest option, the Premium 2.0 plan costs $90 for a single line, or $55 per line on an account with four lines.

What’s included in the AT&T Elite 2.0 plan

For those amounts, the plan includes unlimited high-speed 5G data, prioritized even during network congestion, just like the Premium 2.0 plan, and 250GB of hotspot data (up from 100GB for the other plan). It also includes cellular access for one smartwatch and one tablet per line.

For travelers, Elite 2.0 has unlimited international talk, text and 20GB of high-speed data per month in 210 countries. The Premium 2.0 plan has unlimited talk, text and high-speed data, but only for 20 Latin American countries.

Aside from the data amounts, the Elite 2.0 plan includes AT&T Turbo, a feature normally offered as an add-on that increases data performance for video calling, gaming and streaming on 5G-capable devices. For other plans, AT&T Turbo costs $7 per line per month.

(AT&T Turbo is a separate feature from AT&T Turbo Live, which is designed to boost performance in certain crowded venues such as concerts or sporting events.)
