A few weeks ago, NASA’s robotic Mars explorers were given some time off from hard work while the agency waited out Mars solar conjunction, a natural phenomenon that could interfere with their communications. Leading up to the pause, the Curiosity rover was put in park — but its Hazard-Avoidance Cameras (Hazcams) kept snapping away. In a first for the rover, Curiosity recorded the passage of a Martian day over 12 hours from its stationary position, capturing its own shifting shadow on the landscape as the sun moves from dawn to dusk. It held onto the images until after the conjunction ended on November 25.

Curiosity was given instructions to record the 12-hour sequences a few days before the conjunction began in mid-November, according to NASA. The idea was to see if it could catch any weather events that might crop up. That didn’t end up happening, but the images Curiosity snapped on November 8 are still pretty enchanting. They’ve been pieced together in two videos showing the view from its front and rear Hazcams.

Curiosity’s Hazcams are normally used to help drivers avoid terrain that could be dangerous to the rover. But with the rover parked ahead of its pause in duties from November 11 to November 25, the cameras were freed up for a bit of sight-seeing. Curiosity recorded from its position at the base of Mars’ Mount Sharp from 5:30AM to 5:30PM. It and the other Mars explorers have since resumed their normal activities.

Vizio TVs’ “effective” refresh rates have been confusing customers for years, and the company may now owe payments to some buyers who were misled by the term. As spotted by The Verge, Vizio recently agreed to settle a class action lawsuit in California over what plaintiffs claim is “false and misleading” advertising. While some Vizio TVs are marketed as having a “120Hz Effective Refresh Rate” or “240Hz Effective Refresh Rate,” that describes a result achieved using motion clarity technology. Their actual, native refresh rate in most cases is 60Hz.

Vizio has denied any wrongdoing on its part, but agreed to a $3 million settlement covering all Vizio TVs purchased in California that were advertised with the above descriptions, going back to April 30, 2014 and up until the final court judgment. The final approval hearing is right now set for June 20, 2024. People may be entitled to payments of up to $50, but claims must be in by March 30, 2024. The claim form can be found here. Vizio also agreed to stop marketing its TVs this way and to “provide enhanced services and a limited one-year warranty to all Settlement Class Members.”

NASA’s campaign to gather names for a sort of “message in a bottle” that will fly with its upcoming Europa Clipper mission closes after this weekend, so if you were hoping to participate but haven’t yet made your submission, you’d better hurry up and do so. The signatures will accompany a poem written for Europa by US Poet Laureate Ada Limón, which will be engraved in Limón’s handwriting on a metal plate attached to the spacecraft. Europa, one of Jupiter’s largest moons, is thought to have a deep saltwater ocean beneath its icy crust — and there, the conditions could be suitable for microbial life.

To enter the Message in a Bottle campaign, you just need to go to NASA’s website and fill out a short signup form. The deadline is tomorrow, December 31. So far, more than 2.4 million people have added their names. According to NASA, the names of everyone who participated will be stenciled in tiny, tiny letters onto microchips using an electron beam that can create lines of text smaller than 1/1000th the width of a human hair. These microchips will be affixed to the plate containing the poem.

The Europa Clipper spacecraft is scheduled to launch in October 2024, and it’ll be another six years from then before it reaches Jupiter’s orbit. Once there, it’ll investigate Europa’s potential habitability through a series of close flybys. Europa is one of an estimated 95 moons circling Jupiter and among the longest known to humanity. 

What do you do when the tech world mostly grinds to a halt at the end of December? You reheat your hot takes, force a narrative thread on a company's ups and downs and edit it all up for consumption. 

Yes, it's a little quiet at the end of the year (barring Apple Watch bans), but that won't stop TMA from finding something for me to talk to himself about. We’re looking at a few of the major stories from the last 12 months and .. some other things where I just has to say my piece. And if not on a short YouTube video that's clipped, cropped and pushed into socials, then where? On X? Pschh.

A few days ago, Microsoft released a standalone Android app for Microsoft Copilot, giving you a quick way to access the AI assistant. Turns out the iOS and iPad versions weren't far behind, because they're now available from Apple's App Store. Just like in Copilot on desktop and other AI chatbots, such as ChatGPT, you can type in your question and wait for responses generated by artificial intelligence. In Copilot's case, you'll get responses spun by OpenAI's GPT-4, the company's latest large language model. The free version of ChatGPT, in comparison, is powered by the older ChatGPT-3.5, and you'll need to pay for ChatGPT Plus to get access to the newer model. 

In addition, Copilot on iOS has the capability to turn your words into images. That particular feature is powered by OpenAI's DALL-E 3 text-to-image AI system, which the company previously said is "significantly better" at being able to grasp the final product you want to achieve with the text prompt you type in. DALL-E 3 was also designed to be better at rendering the elements its predecessors were having trouble with, such as human hands. 

This is but the latest Copilot product Microsoft has released since it rebranded Bing Chat. The company also brought Copilot to Windows 10 and then to Windows 11, giving around a billion devices — based on the platforms' user numbers — access to the AI chatbot. With these mobile rollouts, Microsoft is expanding Copilot's reach even more, especially since the apps are free to use.

Firefly Green Fuels, a UK-based company, has developed a new form of jet fuel that is entirely fossil-free and made from human waste. The company worked with experts at Cranfield University to confirm that the fuel they developed had a 90 percent lower carbon footprint than what is used in aviation today, according to the BBC. Tests by independent regulators validated that what Firefly Green Fuels has developed is nearly identical to standard A1 jet fuel.

In 2021, the company received a £2 million grant from the Department of Transport to continue developing its sustainable aviation fuel. Although it’s not yet available commercially, the company says it is on track to bringing its fuel to the global market and it will have its first commercial plant operating within 5 years. The company has already inked a partnership with the budget airline Wizz Air — the name of the company and the source of its potential combustibles could scarcely be a more perfect pairing — to supply it with fuel starting in 2028.

It currently sources its waste from water companies in the UK and takes the refined sewage through a process called hydrothermal liquefaction, which converts the liquid waste into a sludge or crude oil. Solid by-products can also be made into crop fertilizer. The company claims that the carbon intensity of the whole process — which measures how much carbon is needed to produce energy — is 7.97 grams of carbon dioxide per megajoule (gCO²e/MJ). Comparatively, the ICCT says carbon intensity recorded for jet fuel ranges from 85 to 95 gCO²e/MJ.

Organic matter, as the company points out, takes millions of years to develop into the fossil fuels that power cars and planes. Firefly’s solution makes it possible to generate fuel in a matter of days — and more importantly, human waste is a widely available resource. It's unclear if sustainable jet fuel will be more or less expensive than what is currently available. The company could not immediately be reached for comment. However, in a statement, the company’s CEO James Hygate made mention that using human waste is a “cheap and abundant feedstock [that] will never run out.”

The achievement of carbon neutrality in our airspaces has been a longtime goal for regulators and leaders in Europe and the US. While EVs have made headway in the car industry, it might be a while before we see battery powered commercial jets. So in the meantime, solutions for creating more environmentally-friendly jet fuel are welcome.

NVIDIA is set to release a low-powered version of the GeForce RTX 4090 graphics card specifically for the Chinese market to comply with US export rules, as reported by The Verge. The RTX 4090D already has a product page on the company’s Chinese website and it boasts fewer CUDA cores than its similarly-named cousin. It also features a lower power draw of 425W instead of 450W.

Most of the other specs remain the same between the two versions, but the fewer CUDA cores and decreased power draw force a five percent reduction in speed when gaming and using creative applications, according to Reuters. Even with the performance dip, NVIDIA still says the 4090D is a "quantum leap in performance, efficiency and artificial intelligence-driven graphics.”

This is all due to US export restrictions on high-end computer chips shipped to China and Russia, in an attempt to curb both nations from developing technology that could be used in applications like weapons making and surveillance. These rules were announced back in 2022 but officially put into place this year, leaving manufacturers like NVIDIA scrambling to find a solution that met the needs of both Chinese consumers and US regulators.

We knew that the company was going to make new chips specifically for the massive Chinese market, as the restrictions prevented it from selling the original RTX 4090 and a bevy of AI-related GPUs. NVIDIA says the updated GPU “has been designed to fully comply with US government export controls” and added that it “extensively engaged with the US government” throughout development of the chip.

The RTX 4090D will be available throughout China at some point in January, at a price of ￥12,999 or around $1,836 USD. This should help lessen demand for powerful graphics cards in the country, as the aforementioned restrictions have reportedly led to the repurposing of factories to focus on AI accelerators instead of the banned RTX 4090. 

Donald Trump’s former “fixer,” Michael Cohen, used Google Bard to cite made-up legal cases that ended up in a federal court. The New York Times reported Friday that Cohen admitted in unsealed court papers that he passed on documents referencing bogus cases to his lawyer, who then relayed them to a federal judge. Cohen reportedly wrote in the sworn declaration he hadn’t stayed on top of “emerging trends (and related risks) in legal technology.”

Cohen’s legal team filed the paperwork in a motion asking for an early end to court supervision from his 2018 campaign finance case, for which he served three years in prison. After Cohen’s attorney, David M. Schwartz, presented the legal documents to the federal court, Judge Jesse M. Furman of the Federal District Court said he was having trouble finding the three decisions cited by Schwartz (via Cohen).

Judge Furman told Schwartz that if he couldn’t provide documentation of the cases, the attorney needed to provide “a thorough explanation of how the motion came to cite cases that do not exist and what role, if any, Mr. Cohen played in drafting or reviewing the motion before it was filed.” Schwartz must also explain why he shouldn’t be sanctioned “for citing nonexistent cases to the court.” Cohen is a former lawyer who was disbarred after pleading guilty to multiple felonies.

Enter Bard. Cohen said he didn’t realize the AI bot “was a generative text service that, like ChatGPT, could show citations and descriptions that looked real but actually were not.” Cohen also blamed his lawyer, saying he didn’t realize Schwartz “would drop the cases into his submission wholesale without even confirming that they existed.”

Although lawyers using AI chatbots to cite hallucinated cases makes for easy comedy, this flub could have profound implications for a critical case with potential political ramifications. Cohen is expected to be the star witness in the Manhattan criminal case against Trump for allegedly falsifying business records. The Bard flub gives Trump’s lawyers new ammunition to discredit the onetime fixer.

Cohen joins the company of ChatGPT Lawyer Steven Schwartz, who cited made-up cases (sourced through OpenAI’s chatbot) in a civil case earlier this year. He was allegedly joined by the attorney for Fugees rapper Pras Michel. In October, the artist accused his lawyer of using an AI program he may have had a financial stake in to produce his closing arguments.

This is the last weekly deal roundup we'll do this year, but unlike other end-of-year posts, we won't be looking back wistfully at the 2023 deals that once were — all that matters are the ones you can get right now. This week, we're seeing a few sale prices that are still live from Black Friday; snag those before they inevitably go back up. A few new discounts have popped up that actually beat lows from November's shopping holiday, including a Prime-only deal on Amazon's Echo Show 8, all-time lows on Anker charging accessories, and discounts on Apple AirTags and Tile Pro trackers. Until next year, these are the best tech deals that you can still get today.  

Anker charging accessories sale

As part of a larger Anker charging accessories sale at Amazon, the Anker 511 Nano 3 wall charger is down to $16 which is a 30 percent discount and close to an all-time low. It's our top pick for a 30-watt option in our fast charger buying guide. And if you want two USB-C ports instead of just one, you can get the 47W Nano 3 for $21, which is within a dollar of its best price so far. Other notable deals include our top pick for a 65 watt charger from the same guide, the Anker GaNPrime 65W, which is 37 percent off putting it at a new all-time low of $38.

Amazon Echo Show 8

The latest generation of Amazon's Echo Show 8 smart display is now 40 percent off, bringing it to a new all-time low of $90. That's about $15 cheaper than it sold for during Black Friday, but this deal is only for Prime members. The Echo 8 is our favorite Alexa display and Amazon debuted the third-generation of the device at a company event in September. We took time to appreciate the edge-to-edge front glass and new, more refined look — along with the new features. The most notable of the bunch is Adaptive Content, which knows how far you are from the device and displays different content accordingly, such as large format weather when you're across the room and personalized info like calendars and news when you step closer. 

Amazon Echo

If you have a Prime membership, you can use it to get the company's flagship smart speaker, the 4th generation Echo, for $50, which is half price and matches the lowest it's ever sold for, and comes in a full $10 less than it went for during Cyber Week. The latest Echo is our top pick for a smart speaker under $100 because it churns out a good amount of volume for its size and packs in all of Alexa's helpful smart home management and other skills. 

ZOIA Euroburo

Empress Effects is selling its two ZOIA modular synthesizers at a discount. The original ZOIA guitar effects pedal typically sells for $549, but is now 20 percent off and down to $439. The modular synth ZOIA Euroburo mini modular synth is 15 percent off, bringing it down to $607 instead of the $714 MSRP. 

We called the ZOIA "a complex and rewarding modular effects pedal" in our review and gave it a score of 86. While it's likely overkill for someone looking for a standard effects pedal, the ZOIA will give you almost limitless combinations of effects and modules, along with customization capabilities that other models can't match. 

The ZOIA Euroburo is pretty similar to the original ZOIA, but is instead configured into a Eurorack format which you could easily add to a larger modular synth setup. There's a powerful audio processor inside, plus 80 modules and 20 dedicated effects modules. These can be combined to create anything from basic reverbs to complicated microloopers or even full-fledged synthesizers.

Bose QuietComfort Ultra earbuds

We named the Bose QuietComfort Ultra wireless earbuds our top pick for noise cancellation in our updated guide to the best earbuds. Right now Amazon, Walmart and Bose are selling them for $249 or $50 off, which is the sale price the buds hit for Black Friday. The standout feature is the active noise cancellation, but we also appreciated the sound quality bump from the new Immersive Audio tech, which we tested out in our full review. 

Hatch Restore 2

The Hatch Restore 2 is seeing a rare discount at Amazon. It's down to $140 instead of the $200 list price. We recommend the device, which is a combination of a sunrise alarm clock and sleep-sounds speaker, in our guide to sleep gear. The design is attractive and the large, tactile buttons are easy to find and use in the dark or when you're groggy. Hatch offers a vast library of original content with bedtime stories, meditations, music and white noise to help you fall and stay asleep, and a big selection of wake-up pep talks and stretches to get you energized in the AM. Only catch is most of the content isn't free. You'll need to pay $5 per month for full access, the value of which we discuss in our review. 

iRobot Roomba 694

The iRobot Roomba 694 is down to $160 directly from iRobot and at Amazon. That's within a dollar of its Black Friday price and $90 off the $275 list price, though it's been regularly on sale over the past few months. This is our top pick for a budget robot vacuum because it combines an easy-to-use app with good cleaning power. It doesn't have the smart obstacle avoidance or self-emptying features of pricier robot vacs, but at $160, you won't likely get a better deal on a reliable machine.  

Google Pixel Tablet

Google's Android tablet, the Pixel is still down to $399 — a $100 discount that matches what it sold for on Black Friday. It popped back up to full price after the sale, but then at Amazon and Target, it dropped back down in early December and hasn't gone back up. The version with 256GB of storage is also $100 off. The Google Pixel Tablet gets a mention in our guide to tablets. Though we don't think it's more compelling than the Samsung that nabs the top Android spot, it's a good pick for someone who wants a tablet that can handle casual browsing and streaming, but can also act as a smart home display. The included speaker and charging dock prop it up so you can use Google Home or manufacturer apps to control compatible smart lights, speakers, plugs and cameras.   

Blink security camera bundle

A Blink sale at Amazon includes a number of security camera bundles, with discounts of up to 53 percent off. The company often sells bundles of its home security cameras at deep discounts and the combinations and sale percentages vary. Whether these are compelling deals or not depend on what you need for your home right now. If you're in the market for a Blink Mini camera to keep an eye on your home's interior, and would like to pair that up with the latest generation of Blink Outdoor camera, this bundle will save you $83 over buying the two separately and at full price. Both cameras offer 1080p video, two way audio and allow for local storage of clips with the included Sync Module 2. 

Apple AirTag

A bundle of four Apple AirTags is currently on sale at Amazon for $79, which is a dollar less than it sold for on Black Friday. These Bluetooth trackers are our pick for iPhone users to keep tabs on your stuff. You'll need some sort of accessory to attach them to your stuff as the smooth round discs lack any sort of hole or attachment point. But AirTags tap into the largest finding network of any tracker, calling on the passive locating power of nearby iOS devices to find a lost tag in real time. It's not as loud, nor as quick with the left behind alerts as our overall top pick, the Chipolo One. A four-pack of those tags is currently $60.  

Tile Pro 1-pack

A single Tile Pro is down to $22 at Amazon, which is cheaper than it went for on Black Friday and matches the all-time low it hit for July's Prime day. We named it the best Bluetooth tracker for Android users, though it'll work with iPhones too. It's louder than an AirTag, and while the Tile finding network is nowhere near as vast as Apple's it worked well enough in our tests to get us to the approximate location of a misplaced item. The Pro model is also the only Tile with a replaceable battery.   

KitchenAid stand mixer attachments

If you took advantage of KitchenAid mixer sales over Cyber Week or were lucky enough to get one as a gift, you may want to look into snagging a few attachments to make your new kitchen appliance even more versatile. Right now a big assortment of attachments is on sale at Amazon. The pasta roller is down to $75 from $100, the spiralizer is $70 instead of $130, and the ice cream maker set is $70 as opposed to the $100 MSRP. The Classic series stand mixer itself is down to $240, which is about $10 more than it went for on Black Friday. 

Tribit Stormbox Micro 2

The super portable Tribit StormBox Micro 2 puts out decent volume and right now it’s down to $46 instead of the full-price $60 after you click the 5 percent coupon. That puts very close to its all-time low and even beats its Black Friday price last month. We named it one of the best small Bluetooth speakers you can buy in our guide to those devices. There’s a strap in the back that works well on belts, backpacks — or even bike handlebars, so it’s easy to take with you. And on-the-go is where this speaker performs best, as it’s more about portable volume than pure fidelity.
