major smartphone brands, it’s regrettable that Xiaomi does not officially distribute its phones in the U.S. Their smartphones (and the majority of their products, as Xiaomi offers more than just phones) are recognized for delivering excellent value as it underprices the competition with more affordable options. The company introduces smartphone models across various price tiers to rival Samsung, which also caters to both budget and flagship customers. By the end of 2025, Samsung released its economical Galaxy A17 smartphone at a price of $200, and now, Xiaomi is responding with its offering. Its rival is the Xiaomi Redmi A7 Pro.

This is a budget-friendly Android device that’s priced lower than Samsung’s A17. However, if you’re eager to finally see a contender to Samsung’s affordable device at a lesser cost, think twice, as this phone has a caveat. It only supports 4G LTE, 3G, and 2G, and in the U.S., it’s compatible solely with T-Mobile and other networks that utilize T-Mobile’s infrastructure, such as Mint, Tello, Google Fi Wireless, and Metro. The Xiaomi Redmi A7 Pro is available on Amazon for $130 or $140, depending on the color option — you can choose the phone in Black, Mist Blue, or Palm Green.

An unfortunate reality of air travel is that occasionally you may not come back home with your luggage. While carry-on bags are straightforward to monitor, your other luggage, including checked bags containing permitted electronics, faces the possibility of getting lost. With a significant amount of luggage going unclaimed each year, certain items are more frequently misplaced than others according to The Found Report by Unclaimed Baggage. The gadgets most commonly found in misplaced luggage for 2025 were cellphones. That year, more than 51,000 phones were discovered in bags that went unclaimed.

Following that, generic accessories like chargers and cables topped the list with over 41,000 unclaimed items, alongside around 40,000 headphones, which were often left in airplane seatback compartments. Finally, nearly 35,000 tablets were reported as found. While misplacing a cable might not appear overly concerning, some of these discoveries are surprising considering how costly and inconvenient replacing that technology would be. Thankfully, according to Unclaimed Baggage, all these lost devices have their data wiped and are restored to factory settings.

### What to Do If Your Luggage Goes Missing

It’s wise to attempt to keep essential tech with you during flights. Nonetheless, there are certain electronics that the TSA prohibits in carry-on bags. If something goes missing, the airline is responsible for locating your bag and compensating you for the items contained within, though this is subject to terms and conditions that differ based on category, travel location, and more. If your airline has an app for tracking luggage, it’s advisable to utilize that feature. Additionally, if your luggage is lost, you can submit a claim with the airline.

However, if your bag isn’t located within two weeks, most airlines will classify it as lost. Each case is different and depends on your flight routes, the contents of your luggage, and the airline involved. The majority of luggage that remains unclaimed in the U.S. is sent to a warehouse in Alabama, where Unclaimed Baggage manages it. At this stage, items from lost luggage are either recycled, donated, or sold through the Unclaimed Baggage website, similar to any online retail establishment.

### Other Intriguing Gadgets Found in Lost Luggage

While phones were the most frequently found devices in lost luggage for 2025, there were also rarer items that don’t necessarily classify as handy travel gadgets suitable for your carry-on. For instance, a bionic knee was uncovered while still undergoing clinical trials. One of the priciest gadgets found was a T530 thermal camera estimated at roughly $12,000. Additionally, a 2023 MacBook Pro was found with enough accessories to reach an estimated value of $7,200.

For enthusiasts of vintage technology, Unclaimed Baggage recovered a barometer from 1941 and a Kellogg candlestick phone dating back to the 1900s. It’s fascinating to observe the kinds of items that get lost or abandoned as individuals travel around the globe. Therefore, the next time you are flying, be sure to hold on firmly to your cellphone and prevent it from appearing on the 2026 Found Report.

The U.S. Department of Defense has allocated $190 million to Rocket Lab’s cutting-edge HASTE launch vehicle — HASTE is an acronym for Hypersonic Accelerator Suborbital Test Electron — but what’s intriguing is that it is not intended for deep space missions. Rather, it is a low-atmosphere rocket based on Rocket Lab’s Electron Rocket, crafted for hypersonic test flights. A suborbital rocket, for those who might not know, does not attain orbital velocity, hence it returns to Earth without executing any orbits in outer space. This is in stark contrast to the company’s hypersonic rocket that has the potential to rival SpaceX.

A suborbital journey provides a low-gravity environment and facilitates suborbital research to undertake a diverse range of experiments and technology evaluations. This is exactly what Rocket Lab’s HASTE launch vehicle and its ensuing program aim to achieve. In collaboration with the DOD, Rocket Labs will “quickly enhance hypersonic flight tests and advanced aerospace technologies that will shape the future of defense operations.” This initiative is a cooperative effort between the DOD and the Naval Surface Warfare Center Crane Division, dubbed TRMC MACH-TB, or the Test Resource Management Center Multi-Service Advanced Capability Hypersonic Test Bed 2.0. Quite a lengthy title.

In total, this multi-million dollar agreement specifies 20 hypersonic test flights utilizing Rocket Lab’s vehicle over a span of four years. The initial launch in this series is expected to occur “within months” of the contract finalization, so it’s imminent.

What types of research can be conducted during a suborbital flight?

Some of the most significant U.S. space endeavors that were not orchestrated by NASA include suborbital launches, such as the U.S. Space Force’s X-37B orbital test vehicle. As stated by NASA, which also manages separate suborbital studies, numerous activities can be accomplished during these test flights, ranging from Earth science and geospace analyses to biological examinations, robotic evaluations, and recreating in-space experiences. Rockets and aircraft are not the sole means to achieve suborbital altitudes. Research balloons are similarly employed, including one the size of a vehicle that landed on a Texas farm.

However, Rocket Lab asserts that HASTE is “specifically designed for technology demonstration missions,” aimed at expediting relevant hypersonic research while minimizing related expenses and increasing launch availability and frequency. This is significant as conventional hypersonic testing approaches tend to be costly and sluggish in comparison.

The 20 HASTE missions currently planned will also emphasize “providing high-cadence hypersonic capabilities at scale for the warfighter,” fostering innovation for the military and the national security interests of the United States. Most further details are classified, but the research is poised to substantially benefit the armed forces. Importantly, the Mach 5 velocities that HASTE can reach present unique challenges for ground control. Should it be utilized for a more perilous, missile-based deployment, the speed is too rapid for assured tracking and targeting. It also necessitates quicker decision-making due to increased velocities. This represents a “critical technology area” that will yield “the greatest impact, fastest results, and most decisive advantage.”

the revelation of lonsdaleite, referred to as hexagonal diamond, has transformed the landscape. Presently, a team based in China asserts they have successfully synthesized lonsdaleite, producing a diamond with hardness and strength that could compete with traditional Earth-found diamonds.

A few years back, lonsdaleite was uncovered in meteorite samples sourced from Africa, marking not the inaugural discovery of this mineral near a meteor impact. Previously, however, scientists had only encountered relatively minor amounts of lonsdaleite. The recent lonsdaleite identified in Africa featured crystals that may be roughly 1,000 times larger than those from past findings. Such discoveries have validated the existence of hexagonal diamond at least in some part of the universe.

Currently, in a publication in the journal Nature, researchers from China outline their method of synthesizing lonsdaleite in a laboratory setting. While this doesn’t represent the first occasion on which scientists have artificially developed a material or substance that can match the strength and hardness of diamonds

innovative methods to effectively utilize a Raspberry Pi. While they may not be the most robust hardware available, for those enthusiastic about creating DIY projects, these compact, single-board computers prove to be highly efficient. Over the years, they’ve garnered popularity among technology aficionados, DIY supporters, and educators due to their adaptability and cost-effectiveness. The mission of Raspberry Pi’s organization is to “provide high-performance, affordable, general-purpose computing platforms to enthusiasts and engineers globally.” It’s fair to conclude that the organization has achieved this goal, as evidenced by the widespread acceptance of its microcontrollers. Nevertheless, the ongoing memory crisis, partly driven by the needs of AI data centers, has complicated the company’s efforts to keep its prices historically low, although it is striving to mitigate the effects of the shortage on its product offerings.

If you’ve been monitoring the situation with RAM shortages, you’ve certainly noticed the number of companies that have increased their product prices in response. Nintendo even stopped offering its $499 Nintendo Switch 2 “Mario Kart World” bundle due to RAM limitations. Similarly, Sony has raised the cost of its PS5 consoles for the second time in less than a year, and Samsung recently increased the prices of its tablets, smartphones, and laptops by up to $300 in the U.S. This crisis has also impacted Raspberry Pi, prompting the company to announce multiple price increases on its available products to counteract the rising memory costs. Clearly, no products are exempt from the negative effects of RAM shortages on pricing— not even cherished Raspberry Pis.
