Black holes are one of the most powerful forces in the universe, but we had never seen one until the Event Horizon Telescope (EHT) team released the first image back in 2019. Now, the EHT Collaboration has released the most detailed image yet of the same M87 black hole, created with the aid of an additional telescope, that better displays the insane physics behind these supermassive objects. 

The first image was captured in 2017 (it takes a long time to process the data) using eight high-altitude telescopes from locations including Chile and Antarctica. The complex technique required the synchronization of atomic clocks, use of the Earth's rotation and processing of petabytes of RAW telescope data. The result was slightly fuzzy, but clearly showed the expected "donut" with the black hole at the center and accretion disk made of matter inhaled from nearby stars. 

However, the EHT collaboration captured another image a year later using an additional telescope in Greenland. That "significantly" improved the image fidelity, particularly in the north-south direction, according to the EHT. One of the original platforms, The Large Millimeter Telescope, also gained sensitivity by using its full 50 meter surface for the first time. The teams also introduced new data analysis techniques that boosted accuracy.

The result is a sharper and brighter image that also clearly shows the Doppler/Einstein effects that cause a black hole to appear to be brighter on one side. That bright spot actually shifted to the right between the capture of the two images. 

"The biggest change, that the brightness peak shifted around the ring, is actually something we predicted when we published the first results in 2019," said Dr. Britt Jeter from Taiwan's ASIAA. "While general relativity says the ring size should stay pretty fixed, the emission from the turbulent, messy accretion disk around the black hole will cause the brightest part of the ring to wobble around a common center. The amount of wobble we see over time is something we can use to test our theories for the magnetic field and plasma environment around the black hole."

The new image also shows that the science behind the image technique is sound and reproduceable. "Confirmation of the ring in a completely new data set is a huge milestone for our collaboration and a strong indication that we are looking at a black hole shadow and the material orbiting around it," said Dr. Keiichi Asada from ASIAA. 

The EHT Collaboration will continue to advance the science with new observations set for the first half of 2024. At that time, scientists hope to capture multiple images to create the first "video" of a black hole to show its chaotic movements. As before, it could take several years (and the participation of many scientists) to get the final result. 

Last December the state of New Mexico sued Meta for failing to protect children, claiming that Facebook and Instagram algorithms recommended sexual content to minors. Now, an unredacted internal Meta presentation has been revealed, with the company's own employees estimating that 100,000 child users were harassed daily, The Wall Street Journal reported.

According to a 2021 internal document, Facebook's "People You May Know" (PMYK) algorithm was singled out as a primary connector of children to predators. When employees reported those findings to Meta executives, they reportedly rejected recommendations that the algorithm be redesigned to stop recommending adults to minors. 

The feature was responsible for 75 percent of all inappropriate adult-minor contact, according to one employee. "How on earth have we not just turned off PYMK between adults and children?" another employee said. "It's really, really upsetting," added another. 

The issues were particularly insidious on Instagram, according to an internal 2020 memo, with "sex talk" 38 times more prevalent on that platform than Facebook Messenger in the US. In one case an Apple executive reported that his 12-year-old child was solicited on Instagram. "This is the kind of thing that pisses Apple off to the extend of threat[en]ing to remove us from the App Store," said an employee charged with addressing the issue. 

New Mexico claims that Meta has failed to address large-scale predation on its platform, particularly around recommendation algorithms. State investigators originally set up phony accounts for children, providing adult dates of birth, as kids often misstate their ages to access online services that they're not supposed to. Then, they implied that the accounts were being used by children, with one posting about a lost baby tooth and starting seventh grade. The suit alleged that, among other things, the accounts were sent child sex images and offers to pay for sex.

The state further alleges that Meta leaders didn't take action to limit adult predation on minors until late 2022, and still stopped short of strict measure recommended by safety staff. Instead it, only attempted to block suggestions to adults who previously demonstrated suspicious behavior toward children. However, according to a Meta study, 99 percent of accounts disabled for grooming children failed to state their age.

Meta recently introduced measures for teen users on Instagram and Facebook, including stopping non-followers from messaging them and blocking offensive comments. On top of the New Mexico complaint, Meta is facing lawsuits from 41 states complaining it harms the mental health of its youngest users. Another recently unsealed complaint filed by 33 states alleges that Meta "coveted and pursued" users under the age of 13 and has been dishonest about how it handles underage users' accounts when they're discovered.

After making a cameo appearance in the Osmo Pocket 3 camera, DJI's Mic 2 wireless microphone system has officially arrived with some nice upgrades over its popular predecessor. It can now connect directly to your smartphone via Bluetooth, while also offering improved internal recording quality, AI noise reduction, a bigger touchscreen, easier control and more. 

The transmitters come in grey with a new see-through design and DJI introduced a white color option as well. They're slightly smaller than before, but largely resemble their predecessors with a clip, magnetic mount and 3.5mm mic input. The power and link buttons are now on the same side and round instead of oblong, with the record button and USB-C input on the other side. 

DJI

In one welcome change, DJI moved the power-on LED to the sides, rather than near the front as before, where it would annoyingly appear on camera. The DJI logo is front and center, though, so you'll still need a piece of black tape to cover that up. 

The receiver has changed substantially, with a larger 1.1-inch touchscreen and a new thumbwheel to make adjustments easier. DJI has made connecting the transmitter directly to your phone simpler as well via included USB-C and Lightning adapters. 

A big plus of the Mic 2 over other kits like the Rode wireless Go 2 is the charging case that's sold with the two-transmitter kit. It now supports up to 18 hours of use on a charge, up from 15 before, and the transmitters have been upgraded from 5.5 to six hours.

DJI

Topping the list of new features is direct Bluetooth connection support, letting you pair a transmitter mic to your phone (or DJI's Osmo Pocket 3 and Action Cam 4) without the need for a receiver. That'll allow creators on a budget to purchase a transmitter mic by itself for $99, or add DJI's Lavalier Mic for an additional $35. 

Linking a phone is relatively easy — hold the record button for three seconds to put it in Bluetooth mode, then press and hold the link button for two seconds. From there, your phone should detect the transmitter. It worked great with my Pixel 7a, even though it's not on the approved list, and I was able to start recording video with much better quality audio, to say the least. 

There are a couple of caveats: the AI noise cancelling feature doesn't work when connected to a smartphone and you can only use one transmitter at a time. If you have the transmitter/receiver combo, though, you can also get audio by connecting the receiver directly to your phone as before. 

DJI

Speaking of, the Mic 2 has a couple of improvements in audio quality. It promises "brighter and more natural sounding voices" for the interviews or standup work where it's mainly used. And though the original DJI Mic supported internal recording as a backup to camera files, it now captures that at higher 32-bit float quality, letting you max out gain without fearing distortion. It also supports a higher acoustic overload point (AOP), up to 120 dB from 114 dB, meaning you'll see less distortion on higher audio levels. 

The other quality trick is AI noise cancelling, allowing the Mic 2 to lower the environmental noise so vocals stand out better. DJI promises that it works in "complex and noisy environments, such as streets and restaurants." 

A full review is to come, but I tried out the Mic 2 in a variety of situations, including inside a car, riding on a bicycle and in a howling wind. It performed well in nearly all those situations, with all distracting noise blocked in the car and bike shots, leaving just some pleasant environmental sound. However, it was unable to block out a direct 30-40 MPH wind on a sand dune, even with the included wind muff installed. It still worked well enough for me to get the shot, though, which was impressive.

DJI

Key features carrying over from the last model include the option for a safety track recorded at a lower -6 dB (in case you accidentally blow out the levels), an 820 foot range with the transmitter/receiver combo (524 feet in the EU), magnetic clips and a muff for each transmitter. For the receiver, DJI has also included preset gains for different cameras so that it'll work relatively well out of the box. It doesn't include all recent cameras, so hopefully firmware updates will address that. 

With the new options, particularly the smartphone Bluetooth connectivity and Osmo Pocket 3/Action 4 support, the Mic 2 is again likely to strike a chord with creators. It's now available for $349 with two transmitters, a receiver and charging case, $219 for a transmitter and receiver and $99 for individual transmitters. You can also purchase the charging case separately for $69. 

Google has finally copied the homework of its other GPS app Waze, adding support for Bluetooth beacons so you can navigate in tunnels or other satellite dead zones, 9to5Google has reported. The feature has rolled out widely on Google Maps for Android, though is still missing in the iOS version. 

As a reminder, Bluetooth beacons are designed to give you navigation and traffic info underground where GPS signals can't get through. Also known as Waze Beacons, they're "battery-operated, low-energy micro-controller hardware that sends a one-way signal to a user's phone or tablet" without capturing any data from the user, according to Google. They're installed underground in a number of cities include New York City, Paris, Sydney, Rio and elsewhere. Waze first launched the feature in 2016.

The function isn't enabled by default, so here's how to turn it on. In Maps, go to Settings > Navigation Settings and then find the "Driving Options" near the bottom of the list. Under those, you'll see Bluetooth tunnel beacons (provided you have the latest version), and you can toggle that on. 

The feature first started showing up for some beta and other users in October 2023, but is now in the primary release. It should smooth navigation considerably, particularly in tricky tunnels with multiple lanes and exits. It's the latest in a flurry of new features that include EV charging information, AI capabilities, Immersive View and more. 

AT&T is raising its Unlimited plan prices a bit on March 5, 2024, though users will at least get more hotspot data, CNET has reported. Prices for all plans are going up by 99 cents per line per month, but users on AT&T's old Unlimited Elite plan will see no change. 

The new plans are now up on AT&T's website, showing the Unlimited Starter SL plan (replacing the old Unlimited Starter plan) now priced at $65.99, but offering 5GB of hotspot data, up from 3GB. The Unlimited Extra is now the Unlimited Extra EL plan, and costs $75.99 per month with 30GB of hotspot data rather than 15GB. Finally, the new Unlimited Premium PL option supersedes the old Unlimited Premium plan and bumps the hotspot data by 10GB to 60GB (all prices are for one user). 

The company is also boosting the price of its Value Plus VL (previously Value Plus) plan by 99 cents to $50.99. Hotspot data still isn't permitted, but you're now allowed up to 10 lines instead of just one. 

"We are bringing new benefits and added value to our best Unlimited plans," a spokesperson told CNET in a statement. "Customers on our current Unlimited Starter, Extra, Premium and Value Plus plans will receive the additional benefits starting in March [presumably along with the higher rate]. Existing customers will be notified of these changes in the coming days and will have several weeks prior to the effective date to update their plan or make other changes if they'd like to."

AT&T's Unlimited plans compare to T-Mobile's Go5G plans and Verizon's MyPlan options. All get considerably cheaper as you add lines, and include perks like Netflix, Disney and other subscriptions. Last year, the United States ranked 219th in global mobile data affordability, or 19th worst in the world, just ahead of the Marshall Islands and Tuvalu. 

Nikon has taken its imaging and AI prowess in a unexpected direction with a new system that can warn farmers when a cow is about to give birth, Kyodo News has reported. It's designed to reduce the need to constantly check large numbers of pregnant cows during busy birthing seasons, helping farmers improve efficiency.

The system, which costs 900,000 yen per year ($6,200) for a farm with around 100 cows, consists of a security-style camera married to an AI system. It uses a dedicated smartphone application that sounds an alert when a calf is due, allowing farmers to spring into action if required. 

Nikon started training the AI in the fall of 2021, then running proof-of-concept tests on four farms in southwestern Japan in February 2023. The system picks up on signs exhibited by pregnant cows about five hours ahead of labor, like increased movement and the beginning of the release of the calf's amniotic sac. "We want to be able to also detect when a female cow is in heat and other behavioral patterns," said Nikon's Kazuhiro Hirano. 

The system apparently does the job well, according a livestock owner who participated in the tests last year. "We deliver about 60 calves per year and had to check the mothers every few hours from around a month before they are due. This system has been a great help," said Keita Higuchi. 

Nikon is best known for its consumer cameras, but it also manufactures microscopes, X-Ray systems, semiconductor systems, robot vision, virtual production studios and more. The company uses AI tech to aid microscope imaging, but has also recently fought against misuse of fake AI images via new electronic watermarking technology. 

LG is already one of the most prolific EV battery manufacturers in the US, but it wants to build the devices that charge them, too. The company just opened just opened its first EV charger manufacturing facility in the US, a 59,000 square foot plant in in Fort Worth, Texas capable of manufacturing 10,000 units per year. 

The company has already started to assemble 11kW home-style chargers there and will begin producing 175kW fast chargers in the first half of 2024. It plans to built 350kW ultra-fast chargers at some point this year designed for "commercial travel and long-distance transportation," LG wrote. 

The Korean company said it chose Texas as it had existing facilities there and because the state offers "excellent logistics and transportation networks and is home to major operations for companies in industries ranging from automobile manufacturing to finance" (GM, Toyota and Tesla all have vehicle assembly plants in the state). 

LG

LG said it's committed to bolstering its EV charger business in Asia and Europe as well. The company, along with two partners, jumped into the game just two years ago, acquiring a South Korean EV battery charger business called AppleMango (since renamed to HiEV).

LG said at the time that the acquisition would allow it to "create synergy" with its EV battery business, along with products like energy storage and energy management systems. The company is also able to leverage its display expertise by marrying the chargers with "sturdy, dust- and water-proof" outdoor digital display units. 

The move also allows LG to capitalize on a US push to build more public EV chargers. The nation currently has 169,741 charging ports (either DC fast or Level 2) across 65,113 stations, according to the Joint Office of Energy and Transportation. However, the Biden administration wants at least 500,000 public chargers by 2030. "By establishing our EV charger production factory in Texas, we will be able to actively respond to the rapidly growing demand for EV infrastructure in the U.S.,” said LG Business Solution president Jand Ik-hwan. 

Following a cryptic tease during CES 2024, Ayaneo has revealed its Next Lite gaming handheld and it's a confusing product, to say the least. It's designed to compete with Steam Deck, but it doesn't run Valve's official SteamOS — rather, it uses a forked version called HoloISO. It will be priced at a decent $299 and while the controls and screen look good, it packs a less-than-potent processor. 

The Next Lite is equipped with a seven-inch 800p screen, 16GB of RAM and and a 47Wh battery, close to the battery size in the $549 Steam Deck OLED. However, it runs either a Ryzen 7 4500U or 4800U processor with Vega 8 graphics, rather than the Ryzen 7 5825U found on the Next. The former chips are several years old now, so the Next Lite is likely to lag well behind the original Steam Deck, currently priced at $349. 

It also uses Hall effect joysticks to eliminate drift and has a copper heat pipe cooling system. It's equipped with three USB-C 2.3 Gen 2 ports on the top and bottom, along with a slot for full-length M.2 2280 NVMe SSDs. If you'd rather run Windows like most other handhelds, it supports that option and will offer required drivers on the company's official website. 

Ayaneo

The earlier press release was puzzling because Ayaneo talked about a "subscription," but it turns out that it was just about subscribing to get more information. The company also initially said it would ship with SteamOS, which got everyone excited, but it turns out that it won't officially support Valve's operating system. Since then, the initial post has been modified to say that it'll use HoloSO, a third-party SteamOS fork. 

So what does that mean in terms of Steam Deck gaming? Ayaneo said that HoloISO "attempts to bring the Steam Deck's SteamOS Holo redistribution into a generic, installable format, and provide a close-to-official SteamOS experience." In other words, there may not be a guarantee that games will work, given the lack of official support from Valve. 

As mentioned, the Ayaneo Next Lite will cost $299 and come in "vibrant colors" including seafoam green. It's set to start shipping ahead of Chinese New Year on February 10th, 2024. 

We're reporting live from CES 2024 in Las Vegas from January 6-12. Keep up with all the latest news from the show here.

Google has announced that it will eliminate at least 17 features from its Assistant product, following news that it had laid off "hundreds" of employees from the division. The company is cutting "underutilized features" to "focus on quality and reliability, it wrote in a blog post, even though a good number of people may still rely on those functions.

"Beginning on January 26, when you ask for one of these features, you may get a notification that it won't be available after a certain date," wrote Google Assistant VP Duke Dukellis. 

The company didn't specify how removing certain commands will improve Assistant, nor did it describe any specific quality and reliability problems. It did say, though, that improvements in the past were aided by user feedback, so it may have been receiving complaints about Assistant's core usability of late.

The 17 functions being removed include: accessing or managing your cookbook; using your voice to send an email, video or audio message; rescheduling events in Google Calendar with your voice; and using App Launcher in Google Assistant driving mode on Google Maps to read and send messages, make calls, and control media. It also describes what Assistant can still do related to those functions, or alternate ways of doing them. A list is here, though Google said they're just "some" of the affected features.

The company is also changing the way Assistant works on your phone. The microphone icon in the Google search bar will no longer pull up Assistant, but merely start a Google voice search, "which is its most popular use case," Dukellis wrote. The "Hey Google" hot word and power button long-press will continue to activate Assistant as before. 

After laying off 12,000 people last year, Google said it planned to focus on AI in the future, so it's interesting that one of its early AI products is being pruned. Earlier today, Google confirmed that it had laid off hundreds of people from at least three divisions, including Assistant, hardware devices and core engineering. 

At its October Pixel 8 event, the company announced plans to launch Assistant with Bard, a version that generates personalized answers based on events, dates and conversations stored on your phone. However, Google didn't say if that version has anything to do with cutbacks in current Assistant functionality. 

SpaceX sent and received its first text messages sent via T-Mobile using its D2D (direct-to-device) Starlink satellites launched just over a week ago, the company announced. First revealed in August 2022, the project aims to provide satellite internet connectivity to regular cell phones so that T-Mobile customers can stay online even when they're in a terrestrial dead zone. 

T-Mobile said that it aims to publicly launch text services with T-Mobile in 2024, with voice, data and IoT (internet of things) plans coming in 2025. Globally, SpaceX has partnered with Rogers in Canada, Australia's Optus, KDDI in Japan and others. 

The scheme requires larger, special versions of the Starlink satellites with D2D capability. SpaceX launched the first six of those on January 2, completing early tests with no issues. "On Monday, January 8, less than 6 days after launch, we sent and received our first text messages to and from unmodified cell phones on the ground to our new satellites in space using TMobile network spectrum... [indicating that] the system works," SpaceX wrote in a blog post. 

SpaceX

When the plan was announced, T-Mobile CEO Mike Sievert said the technology is like putting a cellular tower in the sky. He added that it could one day eliminate dead zones, allowing people to easily get in touch with loved ones even if they're in the middle of the ocean. 

SpaceX said that the system, which uses LTE/4G (not 5G protocols) is a bit more complicated than cell towers in the sky, though. Since the satellites move at tens of thousands of miles per hour relative to the Earth, data must be handed off seamlessly between them. Doppler shift, timing delays and the relatively low transmission power of smartphones must also be accounted for. 

The two companies aren't the first to test such a system. Working with communications specialist AST SpaceMobile, AT&T successfully conducted the first two-way satellite audio call on its network in April, calling a number in Japan with a stock Samsung Galaxy S22 smartphone. AT&T also complained to the FCC that SpaceX and T-Mobile's plan was "woefully insufficient" regarding the risk of harmful interference to ground-based networks.
