Late last year, Samsung launched its newest generation of affordable A-series phones, starting with the entry-level A17. Following the arrival of the flagship Galaxy S26 line, the company has returned to flesh out the rest of its midrange portfolio. The more affordable Galaxy A37 and Galaxy A57 sport some interesting upgrades, even when compared to some of their pricier siblings.Core specs and featuresBefore we dive into my hands-on impressions, I want to do a quick rundown of each phone's specs as that should help set up (or temper) expectations. As you'd expect based on their numbering, the A37 is the more affordable of the two with a base price of $450 for 6GB of RAM and 128GB of storage. You can also choose 8GB RAM and 256GB of storage for $540. Notably, when compared to the A17, the A37 features a much more recent and more powerful Exynos 1480 chip that brings a big jump in NPU performance and helps unlock much of the phone's newfound AI capabilities. It also comes with a large 6.7-inch AMOLED display, a 5,000mAh battery and three rear cameras. However, two of those will likely get more use than the other as the A37 packs a 50-megapixel main camera and an 8MP ultra-wide, along with a 5MP macro shooter. The Galaxy A37 will be available in four colors: charcoal, white, lavender and graygreen. However, the middle two are Samsung.com exclusives and the last one is only available from Best Buy.

It also features a slightly more powerful Exynos 1680 processor and a higher-res 12MP sensor for its ultra-wide lens, but aside from that, it has the same general camera setup as A37 and the same size battery. One small difference is that the A57 has Bluetooth 6 connectivity and Wi-Fi 6E, but the A37 is still stuck with BT 5.3 and basic Wi-Fi 6.For some reason, the A57 is only available in one color: navy. Sam Rutherford for EngadgetBoth phones come with IP68 ratings for dust and water resistance (which is an upgrade from IP67 on the A36) and 120Hz refresh rates. However, the most important shared trait is that while neither supports wireless charging, they can both take wired power at up to 45 watts, which is actually faster than a base Galaxy S26's limit of just 25 watts. Finally, in addition to six years of OS and security updates, the A37 and A57 are getting some trickle-down AI features from its flagship siblings. Those include improved support for Google's Circle to Search, Object Eraser and better transcription and translation capabilities in the Samsung Voice Recorder app.Galaxy A37 impressionsBoth phones have nearly identical designs, right down to the same screen size and number of cameras. That said, one area where Samsung cut corners on A37 is that it features a plastic frame instead of the A57’s aluminum. But even when you hold them side by side, it's rather difficult to discern between the two. There's no obvious difference in appearance or button layout, so the main way to tell the two apart is by feeling for the cooler touch you typically get from a metal chassis. Alternatively, if you look closely, you'll notice that the A37 has slightly thicker bezels around the outside of its screen. Here's a closer look at the A37's color options. Sam Rutherford for EngadgetCompared to the Galaxy A17, the A37's Exynos 1480 felt significantly snappier and much better equipped for multitasking or AI-based tasks like removing unwanted objects from photos. Regardless, as the less expensive of Samsung's new midrange phone options, the company did a really good job disguising the major differences between the two new models. Galaxy A57 impressionsTo be honest, the A57 wasn't quite as appealing as the A37 due to its higher price and no additional features. The main tool it has that isn't available on its more affordable sibling is Samsung's Best Face camera tool, which allows the phone to analyze people's expressions so you can select your favorite reaction and put it in the photo you want. On paper, its Exynos 1680 chip should be a bit faster, but in normal use, it's really hard to tell. And unlike the A37, which comes in four colors (white, charcoal, lavender and gray/green, depending on the retailer), the A57 is only available in navy. Early thoughtsWhile they look the same, the A57 features an aluminum chassis instead of plastic like on the A37, which should be better for long term durability. Sam Rutherford for EngadgetAs a more powerful and more premium alternative to the $200 A17, the A37 feels like a worthy upgrade for the money. It offers noticeably smoother performance along with a more elegant hole-punch selfie cam (instead of a waterdrop) and stereo speakers (instead of mono). Starting at $450, the A37 can also undercut the Pixel 10a while offering a larger 6.7-inch AMOLED display (versus 6.3 inches for the Pixel) and a smattering of equivalent AI features. And in some ways, the wider selection of colors just reinforces that Samsung is probably placing bigger bets on the A37's market prospects. If I were looking for an affordable Android phone with a big screen, I'd give more consideration to this new middle child in Samsung's A-series lineup.Aside from bezels that are a tiny bit bigger, the Galaxy A37 (left) looks almost exactly the same as the more expensive Galaxy A57 (right).Sam Rutherford for EngadgetAs for the A57, it's certainly not a bad phone, but starting at $550, it suffers from being in a much more competitive price bracket. For those who prefer smaller devices, the $500 Pixel 10a is cheaper while offering even better AI tools, a cleaner UI, wireless charging, a slightly larger battery and unmatched photo quality. However, the A57's biggest rival is arguably another Samsung phone: the Galaxy S25 FE. Aside from slower wired charging, it has an even nicer design, an extra year of software and security updates (seven total) and a proper telephoto camera instead of a macro lens. And while its MSRP is a bit higher at $650, it's regularly on sale for under $600 (or less), which effectively sidesteps the A57's biggest advantage. That said, no matter which one you prefer, more options for affordable gadgets are always welcome — especially with the price of smartphones and PCs increasing due to the global RAM shortage.The Galaxy A37 and A57 will officially go on sale April 9. This article originally appeared on Engadget at https://www.engadget.com/mobile/smartphones/samsung-galaxy-a37-and-a57-hands-on-the-cheaper-phone-might-be-a-winner-120000965.html?src=rss

If the Sonos app saga still has you down, Denon has three new multi-room speakers that give you some fresh alternatives. The company’s Home 200, Home 400 and Home 600 offer audio flexibility with other HEOS-enabled products. These new devices were also designed so that they blend in with home decor better than most speakers, coming in stone and charcoal color options for that purpose. As you progress up in number, the speakers not only get physically larger, but their sonic output is also more robust. The Denon Home 200 houses three drivers and three amplifiers for “natural, room-filling sound” in a compact speaker. More specifically, you get two 0.98-inch tweeters and a single 4-inch woofer. The Home 200 looks a kind of like the Sonos Move 2, although Denon’s new compact unit isn’t portable. However, you can use a pair of them for a stereo setup, or connect two 200s to Denon’s Home Sound Bar 550 and Home Subwoofer for a 5.1 home theater system. Next up is the Home 400, which carries two 0.75-inch tweeters, two 4.5-inch woofers and six amplifiers, in addition to two 1-inch up-firing drivers. Here, Denon says you can expect “a wide, airy soundstage” that provides room-filling audio coverage. What’s more, those upward-facing drivers project sound overhead, so there’s a greater sense of dimensionality and immersion here. Denon Home 600 speakerDenonThe Home 600 is the largest speaker in the new trio, with dual 6.5-inch woofers alongside two tweeters, two midrange units and two up-firing drivers. Denon explains that this configuration offers “deep, authoritative bass” that provides more depth in your tunes than other two models. All three of the new Home speakers have Wi-Fi, Bluetooth USB-C and aux connectivity with the wireless streaming powered by Denon’s HEOS tech. As such, you can connect these Home speakers with up to 64 other HEOS devices — including A/V receivers and Denon’s new DP-500BT turntable — and arrange your audio gear in up to 32 different zones. You’ll have access to tunes from Tidal, Amazon Music HD and Qobuz in the HEOS app, and all three new Home speakers support Dolby Atmos Music where available.The Home 200, Home 400 and Home 600 speakers are available today for $399, $599 and $799 respectively. They’re available from Denon directly or other authorized retailers.

Remember when Japan sent a spacecraft to an asteroid 180 million miles away to scoop some dirt off the surface? Six years on from its arrival to Earth, that sample has yielded some insights about what may have seeded life on our planet. Read on to learn more about the latest findings, and other science news we found interesting this week.  DNA ingredients on RyuguIn 2020, a capsule from the Japanese space probe Hayabusa2 returned to Earth with samples collected from the surface of asteroid Ryugu, and scientists have spent the subsequent years analyzing those materials for clues about the conditions that existed in the early solar system. This week, researchers from Japan reported an exciting discovery: the Ryugu samples contain the five building blocks of DNA and RNA. The findings, coupled with those from other recent studies, could put us closer to understanding how the ingredients for life first made it to Earth billions of years ago. The study, published in the journal Nature Astronomy, found the nucleobases adenine, guanine, cytosine, thymine and uracil — all of which were also found in samples gathered from a different asteroid, Bennu, last year, and before that in meteorites dubbed Murchison and Orgueil. This suggests these nucleobases were widespread in the early solar system, and supports the hypothesis that carbonaceous asteroids like Ryugu and Bennu transported them to Earth, the authors explain in the paper. Ammonia was discovered in the samples as well, which may play a role in how these nucleobases formed. The discovery of these building blocks "does not mean that life existed on Ryugu," Toshiki Koga, the study's lead author from the Japan Agency for Marine-Earth Science and Technology, told AFP. "Instead, their presence indicates that primitive asteroids could produce and preserve molecules that are important for the chemistry related to the origin of life."Bacteria collaborate to eat plastic wasteResearchers in Germany have identified a trio of bacteria that can digest a common plastic additive, but only when working together. The study published in the journal Frontiers in Microbiology found that a "consortium" of bacterial strains (two from species in the genus Pseudomonas and one from Microbacterium) was able to break down several phthalate esters (PAEs), which are often used to make plastic materials more flexible. These chemicals are increasingly finding their way into the environment as plastic pollution grows, and research suggests they can have harmful effects on human health and that of wildlife. The team focused on microbes that could be found right at home in their own lab, taking a sample of biofilm that had formed on the polyurethane tubing of a bioreactor. This sample was then incubated in a growth medium containing the PAE diethyl phthalate (DEP) as the main source of carbon and energy. They eventually ended up with a stable culture of bacteria that could break down DEP, as long as the DEP concentration didn't exceed 888 milligrams per liter, according to a press release. The consortium could gobble up all the DEP in 24 hours at 30 degrees C. It was also able to grow on the PAEs dimethyl phthalate, dipropyl phthalate and dibutyl phthalate.The researchers identified the bacteria in the consortium through DNA sequencing, but found that they were not individually able to tackle the PAEs, suggesting they break down the chemicals through a "cooperative process" known as cross-feeding. The consortium could make for another tool in the pollution-fighting toolbox, with potential to help break down PAEs in contaminated areas or speed up the degradation of plastics that contain PAEs by making them more brittle. "This approach may also be effective in treating industrial plastic waste streams," they note. Hubble witnesses a breakupNewly released images from the Hubble Space Telescope show the unexpected breakup of Comet C/2025 K1 (ATLAS) — Comet K1, for short — as it made its way out of the solar system back in November. A team of researchers that initially set out to observe a different comet ended up switching targets due to technical issues, only to catch Comet K1 right after it started crumbling. Hubble captured three 20-second images between November 8 and November 10 2025, the first of which the team estimates was about eight days after the fragmenting started. During the observation period, one of the comet's smaller pieces began to break up too. Talk about being in the right place at the right time. "Never before has Hubble caught a fragmenting comet this close to when it actually fell apart," said John Noonan, a research professor in the Department of Physics at Auburn University, in a statement. "Most of the time, it’s a few weeks to a month later. And in this case, we were able to see it just days after."
