Apple is reportedly working on an iPad-like smart home device designed to compete against Amazon's Echo Show and Google's Nest Hub products, according to Bloomberg. It would reportedly be "essentially a low-end iPad" that would operate as a hub to control thermostats, lights and security systems, while also allowing FaceTime chats. It could be mounted on walls using magnetic clips or positioned more as a home hub-type device than a regular iPad. 

The company has also discussed the idea of building smart home displays larger than iPads, though there are no other details on those. None of the smart home products would be ready until 2024 at earliest. 

Rumors about potential Apple smart displays have popped up before. Last August, it was reported that the company had four smart home devices in its labs, including a kitchen accessory that combined an iPad with a speaker. (In the same report, Bloomberg's Mark Gurman correctly predicted the new HomePod model that arrived yesterday.) 

Apple is also reportedly working on a new version of Apple TV, set for release in the first half of 2024. It would have a faster processor but carry the same design as the current model. 

Smart home devices with touchscreens represent a potentially lucrative market segment still largely untapped by Apple. Amazon makes several versions of its Echo Show smart display, with prices ranging from around $30 for the Echo Show 8 to $250 for the Echo Show 15. Google has the Nest Hub and Nest Hub Max, priced at $100 and $229 respectively. 

Apple just made a key update to its smart home family yesterday. Following the launch of new MacBook Pro and Mac mini models, it released a new $300 version of its larger HomePad that was discontinued last year. Notably, it features new smart home features along with updates like improved audio, an S7 chip and a lower price. Those include a built-in temperature and humidity sensor, along with a feature called Sound Recognition can monitor for smoke and carbon monoxide alarms and send an alert to your iPhone. 

Amazon plans to wind down AmazonSmile, its giving program that allows buyers to donate to their favorite charities with every purchase, by February 20th, 2023. In its announcement, the e-commerce giant said "the program has not grown to create the impact that [it] had originally hoped" almost a decade after it was launched. Apparently, the program's ability to make meaningful impact was hampered by the fact that it has over 1 million eligible organizations worldwide. Donations were often spread too thin. 

Whenever people use the AmazonSmile website to make a purchase, the company donates 0.5 percent of what they paid to the charity of their choice at no additional cost to them. As a parting donation to participating organizations, Amazon will give them the equivalent of three months what they earned in 2022 through the program. Going forward, the company will focus its charitable work "in other areas where it can make meaningful change." It gave a few examples of its future plans, such as investing $2 billion to build and preserve affordable housing, funding the computer science curriculum for 1 million students across thousands of schools and delivering 12 million meals this year through food banks. 

Amazon didn't expound on what it meant by the program failing to make a meaningful impact. According to Bloomberg through, the company donated almost $500 million to charities over the past 10 years through AmazonSmile, but the average amount per donation is only $230 due to the sheer number of participating organizations. Still, critics can't help but wonder if this is merely one of Amazon's cost-cutting tactics.

If you'll recall, Amazon recently announced that it's expanding its planned job cuts to eliminate over 18,000 roles. Amazon was one of the companies that benefited from COVID lockdowns over the past few years and had to hire thousands of new people to keep up with the demand. Consumers eventually went back to their pre-pandemic shopping habits, and Amazon (with its bottomline affected by the shift) reportedly conducted cost-cutting reviews to figure out which units weren't bringing in money. As a result, Amazon froze hiring, closed brick-and-mortar stores and shut down business units, in addition to cutting jobs. 

Since arriving on the market around 2010, gel manicures have become a staple in nail salons across the US and many parts of the world, and it’s easy to see why. Compared to traditional nail polish, gel variants are more resilient to damage and smudging, and they retain their shine until you remove the polish from your fingernails. Best of all, if you’re the impatient sort, you don’t need to wait an hour or more for a gel manicure to dry. Those benefits all come courtesy of the way the polish cures. Instead of waiting for a gel polish to dry naturally, you place your hands under a UV light, which activates the chemicals inside the gel, causing it to harden.

While the dangers of UV light — particularly in tanning settings — are well-known, before this week scientists had not studied how the ultraviolet lights used to cure gel polishes might affect human skin. You might think what we know about tanning beds applies here, but the devices used by nail salons emit a different spectrum of ultraviolet light. A group of researchers from the University of California San Diego decided to study the devices after reading an article about a beauty pageant contestant who was diagnosed with a rare form of skin cancer.

Using different combinations of human and mouse cells, the researchers found a single 20-minute session with an ultraviolet nail polish dryer led to as many as 30 percent of the cells in a petri dish dying. Three consecutive 20-minute sessions saw 65 to 70 percent of the exposed cells dying off. Among the remaining cells, the researchers saw evidence of mitochondrial and DNA damage, in addition to mutations that have been seen in skin cancer patients.

“Our experimental results and the prior evidence strongly suggest that radiation emitted by UV-nail polish dryers may cause cancers of the hand and that UV-nail polish dryers, similar to tanning beds, may increase the risk of early-onset skin cancer,” the researchers write in a study published in the journal Nature Communications on Tuesday. They warn that a longer epidemiological study is needed before they can conclusively say the use of UV drying devices leads to an increased risk of skin cancer, adding “it is likely that such studies will take at least a decade to complete and to subsequently inform the general public.” 

You might think the advice here is to avoid UV dryers, but it's not so simple. Gel manicures have become an industry standard for a reason. For many people, regular nail polish starts to chip off after a day or so, making a traditional manicure often not worth the time, money or effort.  

Wikipedia is finally getting its first major redesign in a decade, but it may be notable precisely because of how little it changes the core experience. The newly launched rework looks very familiar, and instead eliminates some common hassles. A new sticky header provides quick access to search and article sections, while a revised search shows images and descriptions as you type. It's easier to switch languages, and a table of contents helps you navigate content.

TechCrunch also points to smaller tweaks. A collapsible sidebar lets you remove distractions while reading. The default font size is larger, too, to reduce the strain on your eyes.

The Wikipedia update is rolling out now for English users. Wikimedia has already made the update available to 300 of the 318 active languages on the site. It's already the default for Arabic and Greek readers. The team is still asking for feedback, so don't be surprised if the site continues to evolve.

Wikimedia Foundation makes clear that it hasn't removed any functionality, and that the changes led to real-world gains in testing with international volunteer groups. Users searched 30 percent more often, and scrolled 15 percent less. The redesign is meant to modernize Wikipedia by making it more accessible to a "next generation" of internet users who may not be very familiar with the web, according to the creators. You may not pay much notice to the changes if you're a diehard reader, then, but those just coming online may appreciate the ease of use.

It was only a matter of time until Google launched its own location tracker, similar to Apple's AirTags, Samsung's SmartTag, and of course, Tile. According to the developer (and well-sourced leaker) Kuba Wojciechowski, Google's Nest team is developing a tracker codenamed "Grogu." It'll reportedly include an onboard speaker, as well as support for Bluetooth Low Energy and ultra-wideband (UWB). Wojciechowski found evidence of the tracker when he noticed that Google added support for locator tags in the developer hub for Fast Pair, the Android feature that lets you quickly connect Bluetooth devices. 

While there aren't any specific details at this point, we can expect Google's tracker to work like the competition (attach it to whatever you like, and keep tabs on its location with your phone). It's also unclear if Google can replicate Apple's admittedly slick AirTag experience. Wojciechowski says that the Pixel 6 Pro and Pixel 7 Pro both shipped with UWB modules, which would allow them to direct you to nearby objects acccurately. But he notes that Google's "finder" network won't require UWB — BLE should be enough. 

While Google can't guarantee that every Android phone will ship with UWB, Wojciechowski says Google is working with chipset makers to help them support Fast Pair. That means we could see third-party trackers rounding out the location network, something it's hard to imagine Apple ever allowing. As for availability, Wojciechowski didn't find any specific timing, but he notes that it could be announced at I/O this year. That makes sense, as Google is already far behind the location tracking competition.

We’ve known for a while that Sony planned to bring PlayStation franchises to mobile platforms, but we were hoping for something with a unique hook. Instead, Sony has partnered with the independent developer and publisher Exient (Lemmings, Planet 53) on a mobile game starring LittleBigPlanet’s Sackboy. Ultimate Sackboy is an auto-running game for Android and iOS, launching globally on February 21st.

The title follows a well-worn formula: control a cute auto-running mascot, jumping and swerving lanes to avoid obstacles while snagging power-ups. Like Super Mario Run and other genre standards, you’ll play with your phone in portrait orientation. The plot revolves around the crocheted hero competing in the Ultimate Games, which we imagine as an Olympics for semi-retired video game mascots living in an artisan-crafted world. Unsurprisingly, the game’s Google Play listing mentions ads and in-app purchases, consistent with the trailer’s emphasis on acquiring costumes and cosmetics.

Although we’d love to see publishers like Sony bring something more unique to their phone-based spinoffs, an auto-runner starring a beloved mascot ticks the boxes publishers prioritize on mobile: maximum micro-transaction potential with minimal investment in unique gameplay.

The public launch will follow the game’s closed betas in Australia, Canada, Ireland, Netherlands, New Zealand, Philippines, Singapore, South Africa, Turkey and Malta. You can sign up to pre-register on Google Play, and this page will notify you once it’s available on iOS (it will have iPhone and iPad versions).

Serato launched DJ Pro 3.0 in December last year with new stem separation tools and it was only a matter of time until the company's DAW would follow suit. It’s only about a month later and already stems have arrived with the latest update dropping today: Serato Studio 2.0.

The sampler section of Studio now includes small buttons above the waveform that allow you to target the vocals, melody, bass or drums from any track using Serato's own machine-learning algorithm. It does a great job isolating the respective stem segments quickly, at least once the system has a few seconds to analyze a track. You can then try out variations on-the-fly while a song is playing.

The company recommends an M1 MacBook or higher for the best performance when using stems on Serato DJ and that should certainly carry over here. Although Studio is less of a live-performance tool than the DJ app, it helps to have software that allows relatively seamless adjustments as you go — especially processor-intensive stuff like this.

Stem separation has been a trend over the last year or two and Algoriddim's djay Pro, one of the other leading apps in the market, has had a version of this in its own DJ app for a few years. The company even spun the tools off into a standalone app called Neural Mix Pro. That lets you extract stems for use in other apps, but isn’t a complete workstation for making beats on its own.

Serato has been growing Studio’s toolset into a more comprehensive DAW over time. It's a helpful tool for pros who want a way to sketch out track ideas quickly and it's an approachable introduction for those just getting started with beat making. The addition of stems makes this an especially useful complement to Serato DJ, rounding out the ecosystem to include a DAW and DJ app with deeper customization abilities than ever before. 

Serato Studio 2.0 is available today on the company's website with options including a free limited account, a $10 per-month subscription or you can purchase a full license for the app for $249.

Researchers say they have determined a way to make agrivoltaics — the process of growing crops underneath solar panels — more efficient. They found that red wavelengths are more efficient for growing plants, while the blue part of the spectrum is better for producing solar energy. Solar panels that only allow red wavelengths of light to pass through could enable farmers to grow food more productively while generating power at the same time.

Previous studies have found that agrivoltaics can reduce the amount of water required for crops, since they're shaded from direct sunlight. Researchers at Michigan Technological University determined in 2015 that shading can reduce water usage by up to 29 percent. Majdi Abou Najm, an associate professor at University of California, Davis' department of land, air and water resources, told Modern Farmer that by splitting the light spectrum, crops can get the same amount of carbon dioxide with less water while shielding them from heat.

The researchers put the idea to the test by growing tomatoes under blue and red filters, as well as a control crop without any coverings. Although the yield for the covered plots was about a third less than the control, the latter had around twice the amount of rotten tomatoes. Abou Najm noted that the filters helped to reduce heat stress and crop wastage.

For this approach to work in practice, though, manufacturers would need to develop translucent solar panels that capture blue light and allow red light to pass through. Matteo Camporese, an associate professor at the University of Padova in Italy and lead author of a paper on the topic, suggested that translucent, carbon-based organic solar cells could work. These cells could be applied onto surfaces such as glass.

There are other issues, including the fact wavelength-selective agrivoltaic systems may need to account for different crop types. Harvesting those crops efficiently might require some out-of-the-box thinking too. Still, the research seems promising and, with a growing global population, it's important to consider different approaches to using our resources more productively.

“We cannot feed 2 billion more people in 30 years by being just a little more water-efficient and continuing as we do,” Abou Najm said. “We need something transformative, not incremental. If we treat the sun as a resource, we can work with shade and generate electricity while producing crops underneath. Kilowatt hours become a secondary crop you can harvest.”

Twitter’s ad business is reeling, with its daily revenue reportedly falling by 40 percent from a year ago. According to The Information, over 500 of the company’s top advertisers have paused spending on the platform since Elon Musk’s October takeover. Despite that, Twitter is still attracting and retaining media deals because it’s too lucrative for them to give it up.

Although Musk plans to diversify Twitter away from advertising, the company will likely struggle to break even this year. Since Twitter generated $1.2 billion in the first quarter of 2022, running 40 percent below that would mean it’s bringing in around $8 million daily (and about $720 million for the quarter). Getting in the black this year will depend on the company’s ability to generate $3 billion in revenue while paying $1.5 billion in annual interest from the debt Musk raised for the purchase.

The ad troubles could lead to more cost-cutting. Some big advertisers are reportedly unhappy with Musk’s approach to contact moderation, including reinstating Donald Trump and firing executives in charge of curbing hate speech. Twitter’s workforce has already shrunk by about 75 percent since Musk’s takeover, and it’s easy to imagine more layoffs on the horizon if the bleeding doesn’t stop.

However, Twitter can take some consolation in its ability to attract and retain media partners. According to Axios, the platform still has deals with over three dozen media companies, news outlets (including the Wall Street Journal, Reuters, Bloomberg, Forbes, Conde Nast and USA Today) and sports leagues (including the NFL, NBA, NHL, MLB, NASCAR and PGA Tour) in the first half of this year. They find Twitter too profitable to quit in an uncertain economy — even while balking at embracing it publicly.

Your international money transfers might not be as discreet as you think. Senator Ron Wyden and The Wall Street Journal have learned that US law enforcement can access details of money transfers without a warrant through an obscure surveillance program the Arizona attorney general's office created in 2014. A database stored at a nonprofit, the Transaction Record Analysis Center (TRAC), provides full names and amounts for larger transfers (above $500) sent between the US, Mexico and 22 other regions through services like Western Union, MoneyGram and Viamericas. The program covers data for numerous Caribbean and Latin American countries in addition to Canada, China, France, Malaysia, Spain, Thailand, Ukraine and the US Virgin Islands. Some domestic transfers also enter the data set.

The program exists to help agencies collect evidence of fraud and money laundering, as transfer services aren't required to know customers like banks. This has led to busts for drug cartels and other criminals, TRAC director Rich Leber explained to The Journal. The $500 threshold exists to prevent the system from collecting most data for immigrants remitting money to family in their home countries. Money transfer apps like Apple Cash, Cash App, PayPal, Venmo and Zelle haven't provided data to TRAC, Wyden says.

You need to be a member of law enforcement with an active government email account to use the database, which is available through a publicly visible web portal. Leber told The Journal that there haven't been any known breaches or instances of law enforcement misuse. However, Wyden noted that the surveillance program included more states and countries than previously mentioned in briefings. There have also been subpoenas for bulk money transfer data from Homeland Security Investigations (which withdrew its request after Wyden's inquiry), the DEA and the FBI.

The concern, of course, is that officials can obtain sensitive transaction details without court oversight or customers' knowledge. An unscrupulous officer could secretly track large transfers. Wyden adds that the people in the database are more likely to be immigrants, minorities and low-income residents who don't have bank accounts and already have fewer privacy protectoins. The American Civil Liberties Union also asserts that the subpoenas used to obtain this data violate federal law. Arizona issued at least 140 of these subpoenas between 2014 and 2021.

The Arizona attorney general's office hasn't responded to requests for comment. However, Wyden is already drafting legislation that would bolster privacy for money transfer services and effectively neuter the database. The ACLU, meanwhile, is unequivocal — it says the surveillance system "must be shut down." If nothing else, the findings could draw attention to privacy issues surrounding money transfers.
