Mars snow is dusty, and might even melt into liquid water
Dusty, dark Mars ice could suck up solar energy and maybe even get a little melty.

This story is part of Welcome to Mars, our series exploring the red planet.
Back in 2008, NASA made a big announcement that its Phoenix lander had confirmed water ice near the surface of Mars. A team of researchers has taken a new look at what Phoenix found, combined it with data from NASA’s Mars Reconnaissance Orbiter, and used computer simulations to better understand the dustiness of the ice and what that can tell us about Mars’ climate history.
Not surprisingly, Mars snow has dust mixed into it. «The dustier the ice is, the darker and thus warmer the ice gets, which can affect both its stability and evolution through time,» Arizona State University said in a statement last week. «Under certain conditions, this might also mean that the ice could melt on Mars.»
The team’s paper on the Martian ice has been accepted for publication in the Journal of Geophysical Research: Planets.
«There is a chance that this dusty and dark ice might melt a few centimeters down,» said planetary scientist Aditya Khuller, lead author of the paper. «And any subsurface liquid water produced from melting will be protected from evaporating in Mars’ wispy atmosphere by the overlying blanket of ice.»
The research points to the ice investigated by Phoenix coming from dusty snowfall sometime over the last million years. It will require further work to determine if the ice might actually melt into liquid water, but it’s an intriguing idea.
Understanding water on Mars is key to understanding the chances the red planet might have once hosted microbial life. Current-day Mars is dry, dusty and very cold, which makes it pretty inhospitable, though a study earlier this year suggested Earth microbes might be able to survive on Mars temporarily.
Ice on Mars could also be important for future human visitors who will need water resources. In 2019, NASA released a «treasure map» of water ice that could potentially be reached by astronauts.
The history of water on Mars is complex and often mysterious. Some recent studies had suggested there might be hidden briny lakes at the planet’s south pole, but newer evidence argues they might actually be frozen clays. NASA’s Perseverance rover is currently checking out a former lakebed in the Jezero Crater in a search for signs of ancient microbial life.
The new study on Martian snow and its dustiness gives scientists one more piece to place into the larger puzzle of Mars water. Could there be pockets of puddles on Mars? Perhaps. You might want to pack a straw just in case.

Circle to Search Is One of My Favorite AI Tools. Shame It’s Not on the iPhone Yet
Commentary: While a lot of mobile AI tools feel frivolous, this Google Search capability is intuitive. I just wish it weren’t restricted to Android phones.

Every time I use an iPhone, I lament that it doesn’t have one of the most practical mobile AI tools: Google’s Circle to Search. Until that feature comes to the iPhone — and I really hope it does soon — I don’t think most people will realize just how useful it can be.
Circle to Search is a way to quickly pull up information about anything on your Android phone’s screen. Just long-press the home button and then circle, scribble or tap whatever you want to look up. If you’re scrolling through Instagram and see a vacation spot you’d like to identify, a pair of shoes you want to buy or a word you want to look up, just draw around it and Google will pull up a list of relevant Search results.
You can even use your phone’s camera to point at something, then use Circle to Search to find out more. And a new capability that debuted on Thursday continuously translates text as you scroll through social media posts or switch between apps.

Apple’s Visual Intelligence feature has some similarities to Circle to Search; it uses Apple Intelligence to identify what’s around you and whatever you snap a picture of. A new functionality arriving with iOS 26 will allow the tool to work with screenshots, so you can ask ChatGPT about what’s on your screen, add an event to your calendar or search for a product. But those capabilities are still relatively limited compared with Circle to Search. Plus, Visual Intelligence is available only on iPhone 15 Pro models or later, while Circle to Search is on a much broader range of Android phones.
I’ve used Circle to Search for a variety of tasks, from figuring out where to buy tea sets to identifying a song to looking up the breed of cute cats. (Clearly, the use cases are diverse.) It’s a seamless way of finding relevant links and information about anything that piques your curiosity, without struggling to describe it in a traditional Google search — especially when you don’t know the name of what you’re searching.
But if you do prefer to add words to your query, you can still do that with Circle to Search. Once the results pop up at the bottom of your screen, you can type in the Search bar to get more specific answers and information.
Circle to Search debuted in January 2024 on the Samsung Galaxy S24 series and the Pixel 8 lineup, and it’s now available on the latest Pixel devices as well as on Galaxy S, Z and A phones — meaning it’s not just confined to the priciest devices.
When will Circle to Search come to iPhones?
I’m glad more phones are getting Circle to Search and that it’s become somewhat standard on a handful of premium and more affordable Android phones (and I hope it lands on more). But I’m eagerly awaiting the day this feature arrives on the iPhone. I’m not holding my breath for Apple to announce the arrival of this capability at its iPhone 17 event on Tuesday, but I suppose anything’s possible.
Google hasn’t said anything about bringing Circle to Search to Apple devices, though you can carry out a similar function on iPhones using Google Lens in the Google app and on Chrome. But that’s simply not good enough for me. Circle to Search has been out for nearly two years, and it’s about time it made its iPhone debut in full force.
It’s a contentious time for tech companies like Google, Samsung and Apple, which are racing to crank out the most advanced AI-powered features. So while other Google apps and features like Lens, Drive and Calendar have made their way onto the iPhone, this is a whole different ball game.
But if reports about Apple potentially supercharging Siri with Google’s Gemini are any indication, there’s a high chance the two companies can agree that Circle to Search is a feature that also belongs on iPhones. And once it arrives, you’ll likely wonder how you ever lived without it.
Until then, I’ll just keep wishing I had an Android phone in my hand each time I scroll past a particularly tantalizing teapot on Instagram.

Meta Reimagines Facebook’s Poke Feature to Gamify Gen Z Flirting
The early Facebook feature is still around and has now been gamified by Meta to appeal to younger people.

When was the last time you were poked on Facebook?
The feature, which has endured since the early days of the social-media platform, is still clinging to life and in fact being pushed again by Meta as a way to maintain connections with friends. Originally intended as a way to reach out to other users without actually sending a message or any meaningful content, it has been the focus of soft relaunches in 2017 and 2024.
Meta has now started promoting poking all over again, according to TechCrunch, as interest seems to be rising among younger users. Facebook now has a centralized poke page at facebook.com/pokes where you can view who has poked you, who you’ve poked and who Meta’s algorithm thinks should be the target of your next poking.
Plans for the poke include indicators for poke counts, the option to dismiss pokes and emoji badges similar to those on platforms including Snapchat and TikTok.

This Portable Power Station Was My Lifeline During an Outage. Here’s Why I Recommend It
The Duracell M150 isn’t the biggest battery backup, but it has two killer features most power stations don’t.

I recently had Hurricane Erin blow through my area, resulting in lots of rain, some fallen trees and the seemingly inevitable power outage. It was the worst possible timing since I’m currently in the middle of moving into a new apartment, meaning my Jackery portable power station and emergency lantern are both sitting in a pile of boxes. Fortunately, I still had the Duracell M150 Power Station on my desk, and it helped save the night, allowing me to continue packing in the dark.
It looks like a giant two-tone Duracell AA battery, with a copper accent on the top. The charging hub with multiple high-output USB-C and USB-A ports has a built-in light ring and a dock that keeps it topped up all the time. It usually runs $159, but right now it’s available on Amazon with a new $149 price tag.
There’s also an adjustable MagSafe-compatible wireless charging pad up top, along with a storage compartment to stow away cables. Its larger sibling, the M250, is even featured on CNET’s list of favorite portable power stations for its unique design, though if you want something with more capacity, you should consider our best portable power stations list.

The Duracell’s charging dock and light is the killer feature
The thing about most portable power stations is that you need to top them up periodically or leave them plugged in all the time so they’re always ready for emergencies, at the cost of battery lifespan. That’s the case with the Jackery Explorer 300 power station, which I also own and used as my mainstay power backup option. It’s a good device with pretty of runtime, but it requires me to be frequently plugging and unplugging it, which can be a hassle.
The Duracell M150 makes this process easier with the included charging dock, which keeps the M150 topped up whenever I need it. When my power went out, all I had to do was pull the dock off the charging stand and move it to where I needed it. That’s also where the built-in light came in handy. Unlike the Jackery Explorer 300, an unexpected outage didn’t leave me reaching for my phone’s flashlight. With a press of a button, I got immediate light and I was able to find my way around my dark and cluttered apartment.
The light isn’t as bright as an emergency lantern or camping light, but it’s more than enough to do in a pinch, giving me the time to check my breaker box to confirm that it wasn’t the cause of the outage and to find some back up entertainment options like my Steam Deck and Kobo Libra Color, while also serving as a tabletop light if I needed to head to the bathroom.
The Duracell also stands out for its size and weight. At just 1.8 pounds for the battery section and 0.6 pounds for the included charging dock, you can tote the whole thing around without too much trouble. However, it doesn’t have a carrying handle like the Jackery Explorer 300, which would have been a nice touch for added portability.
Does a portable power station make a good gift?
The Duracell M150 provides power whenever you need it, making it a great gift for those in areas more prone to outages. This can include places like Florida and the Gulf Coast or even people like me who live in older buildings with more decrepit infrastructure.
With its mix of USB-A and high-output USB-C ports and a wireless charging stand, it can charge devices ranging from laptops and phones to earbuds and smartwatches. There are also two additional models, the smaller and more compact M100 and the larger, more capacious M250 so you can pick whichever one suits your needs best. All three come with the charging dock and built-in light.
