Best Kitchen Composters and Food Recyclers (2026)

Published

on

The countertop kitchen composter is a lovely vision. Instead of a smelly bucket of vegetable scraps and coffee grounds breeding fruit flies on your counter or attracting rats to your backyard, you could just put it all into a nifty electric gadget, and at some undetermined point in the future, you’ll have a bountiful supply of nutrient-rich compost to use in your garden.

Unfortunately, none of the more popular electric machines quite do this. Even though some of these devices are marketed as “composters” and have instruction booklets and apps detailing all the ways in which one can use compost, the vast majority of kitchen composters are just going to grind up and dry your food scraps. Your waste output will be greatly reduced in volume and will no longer smell, but if you’re hoping to put eggshells and banana peels into a machine and magically scoop out the kind of compost you’d buy at the garden center, that’s just not going to happen.

That said, you can mix small amounts of these grounds into potting soil in very small ratios, or use them as feeder for a “real” compost pile, but most of these machines are meant for those wanting to reduce the volume of food waste their household produces. This is itself a legitimate goal, as cast-off food makes up 24 percent of municipal solid waste, resulting in the release of methane, a destructive greenhouse gas, as it breaks down in the landfill.

Or maybe you’d just like your food grounds to be odor-free and shelf-stable before adding them to your green waste bin for municipal composting or your backyard compost. In any case, despite critics’ cries of greenwashing and corporate astroturfing, there is still value to these devices. They make people more aware of their food waste. They don’t use as much power as you think they would (around 1 kilowatt-hour was typical). And my top pick, the Reencle Prime, even produces something close to compost.

Updated April 2026: I’ve added the Terra II from GEME and Clear Drop’s Organics Collector to the section of other devices I’ve tried and ensured up-to-date links and prices. I’m currently testing a composter from Airthereal.

Prime Electric Composter

As I mentioned above, none of these machines makes truly ready-to-use compost, but the Reencle Prime comes closest to a traditional compost bin. Popular in South Korea years before it appeared in the US, the Reencle arrives with a starter bag of ReencleMicrobe (which can be purchased separately for $65) containing activated carbon, wood pellets, glucose, and a trio of patented microbes ready to chow down. There’s also a prefilled carbon filter that slots into the back.

At 14 x 15 x 22 inches, the Prime is too large for a kitchen counter, but it conveniently operates much like a heated trash can. The lid can be opened via a sensor at the bottom or a button on the control panel, and in goes your organic matter. That’s it. There are no cycles, tablets, or auxiliary buckets to worry about. Even the app is totally optional. Within hours to days, depending on the item, the scraps are broken down into a material resembling a cross between dirt and sawdust.

The smell isn’t always pleasant, but it can usually be mitigated by using the control panel’s Dry and Purify buttons or by adding what, in composting lexicon, is called “browns”—dry, carbon-rich materials like bread or shredded paper.

The Reencle also tends not to smell when it’s being fed its preferred diet of 1.5 pounds of scraps per day. Unlike other machines, it can also accept meat and dairy. For larger households, there’s the Reencle Gravity ($649), which is a couple of inches taller and can accept 3.3 pounds of waste a day. I also tested this and found it to be significantly quieter than the Prime—not that the Prime is noticeably loud, only about 30 decibels—but the Gravity is nearly silent, which is a nice bonus.

When the volume reaches the fill line, the Reencle grounds can be scooped out, mixed with potting soil at a 1:4 ratio, and left to cure for three weeks (I used a large tub in my garage). Afterward, it can be used for both outdoor and indoor plants. I have used this resultant mix to positive effect both indoors and outdoors.

Prego put down the pasta and made a $20 device to record your family dinners

Published

on

Yes, that Prego — the pasta sauce people. The company has teamed up with StoryCorps, a nonprofit dedicated to preserving everyday American conversations, to release a physical recording device built specifically for the dinner table. It’s called the Connection Keeper, and the whole point of it is to capture the kind of conversations that happen when everyone puts their phones down and actually talks to each other.

What it is and how it works?

The Connection Keeper is a small puck-shaped device, apparently nodding to the round lids on Prego’s pasta sauce jars, that you place in the center of the table. Hit the button on top, and it starts recording. That’s more or less the entire interface. There’s no screen, no app, and no Wi-Fi setup needed for this. Just a button, a USB-C port, and a 16GB microSD card that can store up to eight hours of conversation.

It can also prompt your family with conversation starters if dinner has gone quiet and someone’s just pushing food around their plate. 

Where do the recordings go?

Once you’re ready to do something with your recordings, you move them over to a StoryCorps portal via USB-C. StoryCorps keeps everything private by default, and Prego says the portal is encrypted with full privacy controls, though the specifics of how all that works haven’t been fully laid out yet. Recordings will be accessible and shareable starting May 4.

Advertisement

If you want to, you can also contribute your conversations to StoryCorps’ public archive, where anyone online can listen. That’s a meaningful thing to consider before uploading, especially if kids are involved, or anyone at the table didn’t know they were being recorded.

At $20, the price is quite reasonable for what it is. The catch is that Prego plans to produce fewer than 100 units, with sales opening on April 27. So if this sounds like something you’d actually use, you’ll want to move quickly once it goes on sale. It’s a weird product from an unexpected brand, but in a world where every device is fighting for your attention, something that quietly sits on the table and just listens feels almost radical.

A sweet idea, with a slightly complicated aftertaste

The Connection Keeper is a genuinely sweet idea on the surface. There’s something almost nostalgic about a screenless, button-press recorder sitting in the middle of the dinner table, quietly catching the jokes, the arguments, the stories your grandmother tells for the third time that you’ll one day wish you’d heard a fourth. But the moment you start thinking about what actually happens to those recordings, the warm feeling gets a little complicated.

Your dinner-table conversations are as personal as it gets. The things said over a bowl of pasta on a Tuesday night, the offhand comments, the vulnerable moments, the stuff nobody outside that room was ever supposed to hear. Handing any of that over to a portal, even one that claims to be encrypted and private, asks for a level of trust that Prego and StoryCorps haven’t fully earned yet, mostly because they haven’t fully explained themselves. What does “full privacy controls” actually mean in practice? Who has access to the servers? What happens to your recordings if StoryCorps shuts down or gets acquired? These aren’t paranoid questions. They’re reasonable ones that any company asking you to record your family should have ready answers for before the product goes on sale, not after. Until those details are out in the open, the Connection Keeper is a device with a lot of heart and not quite enough transparency to match it.

Sennheiser HD 480 PRO Headphones Launch: Closed-Back Studio Model Targets Creators and Engineers

Published

on

Sennheiser isn’t waiting around for its consumer business questions to get sorted out. In 2026, the brand is pushing forward where it still carries real weight, professional audio, with the launch of the $479 HD 480 PRO, a closed back studio headphone that builds on the open back HD 490 Pro introduced in 2024.

Positioned at the top of its 400 series closed back lineup, the HD 480 PRO is aimed squarely at working environments like tracking, monitoring, and live use where isolation actually matters. Sennheiser is framing it as its most versatile pro headphone to date, designed to handle recording and production duties while still being usable for critical mix decisions. Patents covering fit, comfort, and noise decoupling suggest this is more than a simple closed back variation.

More importantly, it’s a reminder that while the company’s consumer side direction remains uncertain, the pro division is still doing what it has always done, building tools that people in studios and on stages can rely on.

Sennheiser HD 480 Pro Headphones Angle

The HD 480 PRO is designed to address two common issues with closed back headphones: inconsistent bass accuracy and long term comfort. Sennheiser is aiming for controlled, reliable low end while keeping the fit comfortable enough for extended use in recording, tracking, and monitoring across studio, live, and mobile workflows.

Achieving accurate low-end performance in a closed-back design has always been a balancing act. Isolation helps with tracking, but it often comes at the expense of bass control and realism. That’s the gap Sennheiser is trying to close with the HD 480 PRO.

With closed-back headphones, a good reproduction of the low-end is usually difficult to achieve. This is where the HD 480 PRO excels. Compared to other closed-back headphones, they are a lot tighter on the bass, their low-end is super-accurate and realistic,” notes Jimmy R. Landry, Category Market Manager, Music Industry at Sennheiser.

Who Is the Sennheiser HD 480 PRO For?

Whether used in the studio by producers, mixers, musicians, and recording engineers, or in live settings by FOH and monitor engineers, the HD 480 PRO is positioned as a flexible tool for monitoring, recording, and production, with the added claim that it can be used for mixing. Sennheiser is targeting users who need a consistent reference across different environments, including mobile use.

The tuning focuses on accuracy and a relatively neutral frequency response, with controlled low end intended to translate reliably across other systems, whether that’s home speakers, car audio, or PA setups.

Knowing that you can rely on what you’re hearing is everything; that’s what you get with the HD 480 PRO.” ​ Jim Kaufman, producer

​“When I’m going to be mixing on headphones outside my studio, it’s imperative I have a pair that I trust. With the HD 480 PRO, to have this level of quality and accuracy in a closed-back headphone is amazing.” ​ Will Brierre, mix engineer

​“As producers, we have to receive the best sound to our ears that we can. Every detail is important. When you’re wearing the 480s, you’re immersed in the sound, completely undistracted by the outside world.” ​ Young Chencs, artist and producer

Drivers

The HD 480 PRO uses 38mm dynamic drivers with neodymium magnets, paired with lightweight voice coils intended to improve efficiency and overall responsiveness.

Comfort and Shielding

The HD 480 PRO uses a multi-stage passive isolation design to help reduce external noise and keep the focus on the signal. The ear pads include grooves to accommodate glasses, which helps maintain a more consistent seal, an important factor for stable bass and overall accuracy. Angled earcups position the drivers more precisely, with the goal of delivering a consistent listening experience.

Comfort is of paramount importance when headphones are a work tool,” adds Gunnar Dirks, Senior Product Manager for professional headphones. “Engineers often spend hours on end in their sessions. They need a lightweight, ergonomically designed pair of headphones to keep focus and concentration up. The HD 480 PRO eliminates any pressure points and fit every head precisely and comfortably even if you’re wearing glasses.”

Connectivity

Like the open-back Sennheiser HD 490 PRO, the closed-back Sennheiser HD 480 PRO is a wired-only design. To add some flexibility, it includes input jacks on both earcups for detachable cables, allowing users to choose their preferred configuration or adapt to different studio setups. The earcups are also angled to position the drivers more precisely, with the goal of maintaining a consistent listening experience.

Vibration Attenuation System

A series of design features grouped under the term “Vibration Attenuation System” eliminates unwanted vibration, reflections, and distortion, preserving the clarity of the signal. Ultralight voice coils ensure authentic and dynamic reproduction.

Like its open-back counterpart, the HD 490 PRO, the HD 480 PRO benefits from several Sennheiser-patented features.

Special Axes Geometry: The mechanical design of the 480 enables the headphones to optimally adapt to the head and maintain an equal contact pressure no matter what the shape of the user’s head. The listening experience is consistent across users.

Comfort Zone for Glasses: The ear pads are designed to avoid excessive pressure on the temples, using a softer contact zone that helps maintain a proper seal while improving long-term comfort.

Blocking Cable-borne Noise: A coiled section near the earcup connector helps reduce cable-borne noise, limiting the transfer of mechanical vibrations from handling or contact with surfaces like a desk into the earcups.

Daily Professional Use

The detachable cable can be connected to either the left or right earcup, allowing for more flexibility depending on the setup and helping keep the cable out of the way during tasks like instrument tracking. The earcups are also braille-marked for easier identification. Designed by Sennheiser’s professional team, the HD 480 PRO is built with long-term use in mind and aimed at delivering consistent performance over time.

HD 490 PRO or HD 480 PRO?

The open-back HD 490 PRO and closed-back HD 480 PRO are at the top of the 400 series of purpose-built professional audio headphones. So which one is best for which application?

Our developers have been working painstakingly to bring the sound of the closed HD 480 PRO as closely as possible to that of the open HD 490 PRO. Which model is the better choice for you really depends on how you work,” explains Gunnar Dirks. “The open HD 490 PRO will be ideal for mixing in quiet environments, while I would recommend the closed HD 480 PRO for applications where you need isolation, for example, when you’re tracking vocals in the room, when monitoring or using them as an FoH reference, or simply when you’re working in the same space as others.

The Bottom Line 

There’s some uncertainty around Sennheiser’s consumer business, but the professional side remains separate for now, which means products like the HD 480 PRO and HD 490 PRO are not directly affected.

The HD 480 PRO (and PRO Plus) stands out for its focus on flexibility within a closed-back design—dual-sided cable entry, attention to long-term comfort, and an effort to deliver more controlled low-end performance than is typical for this category. It’s clearly built as a working tool rather than a lifestyle product.

What’s missing is anything beyond wired connectivity and a broader feature set—there’s no DSP, no wireless option, and no attempt to blur the line into consumer use. That’s intentional, but it narrows the audience.

Competition is strong across multiple price points, including the Beyerdynamic DT 770 PRO X and Beyerdynamic DT 990 PRO X at the lower end, and models like the Final DX3000CL and Meze Audio Strada further up the ladder.

These are aimed at professionals and serious creators who need a consistent, reliable reference for tracking, monitoring, and potentially mixing, especially in environments where isolation matters. The decision ultimately comes down to fit and comfort as much as sound, which makes a hands-on demo less of a suggestion and more of a requirement.

Growing Aluminium-Copper Alloy Crystals Using Hydrogen

Published

on

Having molten aluminium interact with atmospheric water forms a source of hydrogen which can be rather problematic if you’re trying to cast aluminium parts. As the molten metal cools down, the dissolved hydrogen is forced out, creating bubbles and other flaws that make aluminium foundries rather upset. While you can inject inert gases to solve the problem, you can also lean into this issue to make some rather fascinating aluminium crystals and geodes, as [Electron Impressions] recently did.

The key here is to use a eutectic Al-Cu alloy at around 45% Cu by weight, as this alloy readily forms large crystals as it cools down. With hydrogen injected into the molten metal, this hydrogen forms large bubbles inside the cooling metal with crystals clearly visible.

A way to create proper geodes involves very slow cooling and pouring off the still molten metal before the eutectic point is reached. As can be seen in this video, this creates a rather impressive looking geode after it’s been smashed open. This also gives a good clue as to how these geological features form in nature, although one does not typically observe Al-Cu alloy geodes in the wild.

China’s Apple App Store infiltrated by crypto-stealing wallet apps

China's Apple App Store infiltrated by crypto-stealing wallet apps

A set of 26 malicious apps on Apple App Store impersonate popular wallets, such as Metamask, Coinbase, Trust Wallet, and OneKey, to steal recovery or seed phrases and drain them of cryptocurrency assets.

The threat actor used multiple methods to imitate official products, including typosquatting and fake branding, to lure users in China into downloading them.

Because such apps are restricted in the country, the attacker published them as games or calculator apps, likely in the hope of being perceived by the users as a trick to bypass the bans in the country.

image

Kaspersky researchers say that all 26 fake apps are part of the same campaign, which they named FakeWallet, and associate them with the SparkKitty operation that has been running since last year.

Once opened, the apps redirect users to phishing pages designed to appear as legitimate portals for the crypto services.

These sites convince victims to download trojanized wallet apps using iOS provisioning profiles, a legitimate enterprise feature that is abused to sideload malware onto their devices. The same technique was also observed in SparkKitty.

The trojanized apps contain additional code that intercepts mnemonic phrases during wallet setup or recovery screens, encrypts them with RSA and Base64, and sends them to the attacker.

For cold wallets like Ledger, attackers rely on in-app phishing prompts that trick users into manually entering their seed phrases via fake security verification screens.

These phrases, which are only held by the rightful wallet owner, are intended for wallet porting/recovery to new devices and require no further confirmation or passwords.

Hence, threat actors can use them to restore the victim’s wallet on their own devices and drain the wallet without the possibility of recovering the funds.

Kaspersky noted that the campaign primarily targets users in China. However, the malware itself has no geographic restrictions, so it could affect users globally if the operators decide to expand their targeting scope.

Cryptocurrency holders are advised to double-check the publisher of the apps they download, even from official app stores, and use only the links provided on the official website.

Advertisement

Last week, it was uncovered that a fraudulent Ledger app that made it into Apple’s App Store stole $9.5 million worth of cryptocurrency from 50 macOS users.

Apple has removed all 26 FakeWallet apps from the App Store following Kaspersky’s responsible disclosure.

BleepingComputer has contacted Apple with questions about the threat actor’s process to bypass the company’s App Store verfications but we have not received a response by publication time.

What Is The Top Speed Of The Artemis II Rocket?

Published

on





Artemis II’s recent launch filled the public with a sense of wonder and awe on the grandest scale. Not since 1972 (Apollo 17) has man attempted to travel to the moon for exploration, which adds even more excitement to this recent mission. While spectators — both in person in Florida and on TV — surely appreciated the historic nature of the mission, the most immediate takeaway is the raw, visceral punch of the explosive launch. Sending such a massive rocket to break free of Earth’s gravitational pull and punch through the atmosphere into space requires a staggering amount of power. 

It takes 8.8 million pounds of thrust to be exact, which violently propelled the 322-foot NASA rocket into space. Just one of the liquid hydrogen and oxygen-powered rockets could power almost a million miles of streetlights. The Artemis II SLS (Space Launch System) topped out at a staggering 24,500 mph, the velocity required to reach the moon. This speed was in line with what the crew of the Apollo 13 mission experienced in 1970, which reached similar top speeds of 24,247 mph.

There were some concerns about the structural integrity of the Orion capsule. Thankfully, its heat shield held up during the reentry phase as the craft safely returned in one piece.

A warp speed win for humanity

But this wasn’t the whole story. Artemis II didn’t simply thrust to the Moon in a straight line at a constant speed. The flight began with SLS launching Orion into Earth’s orbit, fighting hard against gravity, before passing through the atmosphere’s layers and into space.

As Artemis II ascended, it reached speeds in excess of 24,000 mph, though the exact speed depends on the frame of reference. At its closest approach to the Moon, the rocket hit 60,863 mph relative to Earth. However, relative to the Moon, the speed was measured at 3,139 mph. Either way, these speeds are hard to relate to, as even an F-35 Lightning II fighter jet tops out at around 1,200 mph.

Advertisement

As the Orion spacecraft re-entered Earth’s atmosphere, it reached speeds of roughly 25,000 mph before slowing dramatically in Earth’s atmosphere and safely parachuting into the ocean at splashdown. NASA’s coordination, planning, technical prowess, advanced engineering, and brainpower — to say nothing of the crew’s bravery — speak to mankind’s ingenuity and thirst for exploration.

The crew laid the foundation for future missions and lunar research. Who knows where modern space travel could go next? But what is certain is that we all got to watch history being made by some very brave people, at unbelievable speeds.

Kerry Group expands Cork facility as lactose-free demand grows

Published

on

The global lactose-free products market is poised to grow from around $19.5bn in 2026 to $36.5bn by 2034.

Irish food giant Kerry Group has opened an expanded biotechnology manufacturing facility in Cork as it targets the growing global lactose-free market.

The facility, based out of Carrigaline, will help the company increase its capacity to produce lactase enzymes needed for lactose-free and sugar-reduced dairy products.

Lactase is a natural enzyme produced by humans to digest lactose, though a majority of adults worldwide cannot digest lactose efficiently. Market research suggests that the global lactose-free products sector is poised to grow from around $19.5bn this year to $36.6bn by 2034.

Advertisement

The Carrigaline site supports 200 clients across 80 countries. Lactase enzymes produced at the site are used to process more than 2m tonnes of milk annually, reaching around 28m consumers worldwide, Kerry said.

The expanded facility, alongside the company’s Kildare-based Global Innovation Centre and a biotechnology centre in Germany, established last year, are expected to help accelerate Kerry’s lab-to-commercial pipeline.

The company said it is “well positioned” to support the next phase of growth in the lactose-free market, with the expanded centre acting to link advanced enzyme engineering and strain development with large‑scale manufacturing.

“This investment translates decades of biotech research into scalable, real‑world capability,” said Shane McGibney, the president and CEO of biotechnology solutions and transformation at Kerry Group.

“By strengthening the link between enzyme engineering and industrial production, we’re able to move innovations more efficiently from the lab to the production line – helping customers access reliable supply and bring new products to market with greater speed and confidence.”

Minister for Enterprise, Tourism and Employment Peter Burke, TD added: “This facility demonstrates how industry, skills and innovation come together to support the future of Ireland’s food and biotechnology sectors.

“As a global leader in food, Kerry Group continues to play an important role in advancing high-value capability from its Irish base. Manufacturing sites like Carrigaline help move innovation towards scale and strengthen Ireland’s position in advanced manufacturing.”

KelpDAO suffers $290 million heist tied to Lazarus hackers

KelpDAO suffers $290 million heist tied to Lazarus hackers

State-sponsored North Korean hackers are likely behind the $290 million crypto-heist that impacted the KelpDAO DeFi project on Saturday.

The attack reportedly also impacted the lending protocols Compound, Euler, and Aave, with the latter announcing a freeze and blocking new deposits or borrowing using rsETH as collateral.

KelpDAO is a decentralized finance (DeFi) project built around liquid restaking on the Ethereum network. It accepts user ETH deposits, restakes them, and returns a liquid token named ‘rsETH,’ that represents the restaked position.

image

The rsETH token is meant to help users keep earning restaking yield, while it stays usable across DeFi, including cross-chain via LayerZero, an inter-blockchain communication protocol and interoperability layer.

On April 18, KelpDAO announced that it detected “suspicious cross-chain activity” involving rsETH, forcing it to pause rsETH contracts across the Ethereum mainnet and L2s.

The project launched an investigation with the help of LayerZero, Unichain, and other partners.

Tweete

Blockchain activity showed that around 116,500 rsETH were stolen, around $293 million in USD value, and went through Tornado Cash to hide the trace.

According to additional details that LayerZero shared today, the attack targeted the verification layer (DVN) used to validate cross-chain messages for rsETH.

Specifically, the attackers compromised some RPC nodes used by the verifier, feeding it falsified blockchain data, while simultaneously DDoS-ing healthy RPC nodes to force the system to rely on the “poisoned” ones.

Advertisement

This allowed a fake cross-chain message to be accepted as valid. The system confirmed transactions that never actually occurred on-chain and enabled moving the rsETH without authorization.

Based on preliminary evaluation of the attack indicators, LayerZero believes that the infamous Lazarus hackers are likely responsible for the heist.

“Preliminary indicators suggest attribution to a highly sophisticated state actor, likely DPRK’s Lazarus Group, more specifically TraderTraitor,” stated LayerZero.

The protocol also noted that the incident was isolated to rsETH and that there’s no broader contagion across other apps or assets.

While the KelpDAO breach constitutes a major loss so far this year in terms of the stolen amount, the Lazarus Group has also been linked to another large theft, $280 million from the Drift Protocol.

According to a post-mortem report, that attack was the result of a six-month-long, carefully planned operation that involved malicious agents attending conferences and $1 million deposits into the project.
