Microsoft is changing one of Excel’s most familiar rules: a cell no longer has to contain just one value. The company has introduced lists, arrays in cells and nested arrays, giving users new ways to keep multiple pieces of information together without turning them into a single block of text.

The features are currently rolling out as previews to Excel for Windows and Mac Beta Channels. Microsoft says the behaviour may change before general availability and recommends against using the features in important workbooks at this stage.

Excel lists make multiple values easier to manage

The simplest part of the update is the new Lists feature. Instead of putting several values into separate cells or combining them into ordinary comma-separated text, users can store multiple individual values inside one cell.

For example, a project could have several owners listed in a single cell, while a survey response could contain multiple appointment times. With lists, Excel keeps those entries separate internally, allowing users to filter individual values and use them in calculations.

Creating a list involves selecting Insert > List or pressing Ctrl+J, then entering or pasting items separated by commas or semicolons, depending on regional settings. Users can later edit individual entries by double-clicking the cell or pressing F2.

The feature also changes how filtering works. Instead of treating a comma-separated cell as one large piece of text, Excel can filter by individual items. Referencing a list can also return all its values, allowing them to spill into separate cells when needed.

That could make spreadsheets containing project assignments, survey responses or other multi-value data considerably easier to organise.

Arrays bring a much bigger change to spreadsheets

Microsoft is also introducing arrays directly inside cells, including nested arrays. Arrays can now exist as values or formula results inside a single cell and can have different sizes and shapes. Users can also wrap spilling formula results in braces to keep the entire result inside one cell.

Nested arrays take this further by allowing arrays to exist inside other arrays. Microsoft says formulas that previously returned truncated results or a #CALC! error in some array-of-array situations can now return the complete nested result.

To work with these structures, Excel is gaining four new functions: FLATTEN, HAS, HASANY and HASALL. FLATTEN can remove levels of nesting, while the HAS functions can check whether a particular value, some specified values or all specified values appear within an array.

For power users, the change could open up new spreadsheet designs. Microsoft demonstrates a run tracker where different numbers of kilometre splits can be stored in the same row while statistics are calculated alongside them.

There are still limitations. Conditional formatting, data validation, charts, PivotTables, Power Query and Find & Replace do not yet fully support list and array values. The features currently require specific Beta Channel builds, and nested-array calculations require Compatibility Version 3.

For now, Microsoft is treating this as a preview rather than a finished Excel feature. But if the rollout goes smoothly, the humble spreadsheet cell is about to become considerably more capable.

• Panasonic Let’s Note SC7 weighs just 919 grams but passed drop tests from both 76 and 30 cm
• The chassis meets the US military’s MIL-STD-810H toughness standard
• Battery testing returned nearly 23 hours of continuous everyday use

Japanese manufacturers have long built a reputation for producing remarkably light business notebooks, with some models weighing under a kilogram entirely.

Panasonic has now expanded that lightweight lineup with the Let’s Note SC7, a compact notebook weighing just 919 grams total.

Ripple effect: Microsoft may be backing away from the Copilot+ PC branding, but it’s doubling down on the bigger idea behind it: turning AI into a layer that actively runs your computer and gets work done for you. Its latest Copilot overhaul pushes that vision further than before, combining Office, coding tools, and autonomous agents into what CEO Satya Nadella calls a “new OS for work.” Public testing begins in the coming weeks.

Microsoft recently unveiled a major overhaul for Copilot’s business tools. The new suite hands the AI assistant more control in Office, embeds GitHub Copilot’s functionality into professional toolchains, and automatically coordinates tasks between team members.

The new Copilot implementation, which Microsoft CEO Satya Nadella calls a “new OS,” consists of several parts. One of them, simply called Home, lets users chat with Copilot as it examines files to offer recommendations on how it can help. Home can also take over Office 365 apps such as Word, Excel, and PowerPoint to automatically draft files for users to edit.

Another tool, Code, builds apps based on natural-language prompts using the same tools as GitHub Copilot. Microsoft claims that Code uses Microsoft IQ to maintain contextual knowledge of users’ work environments beyond what it currently sees onscreen.

Lastly, Autopilot, a rebrand of Scout, offers the highest level of automation. After users provide it with a role and an objective, Autopilot handles various tasks such as scheduling meetings, following up with contacts, watching channels, starting and resuming projects, and more, all without further human input. The cloud-hosted feature also works 24/7, working across Teams, Outlook, documents, and other programs while remaining in constant contact with teammates.

Home and Code will enter Microsoft’s Frontier program in the coming weeks, while Autopilot will be available in private preview at the end of this month. Another aspect of Home, called Today, will enter private preview in October. Today aims to show users a unified information space with details from emails, Teams chats, meetings, and other sources while also drafting documents and proposing schedules.

Nadella’s “Copilot OS” claim sounds a lot like the supposedly defunct Project Aion, which would have become a separate OS built around Copilot running within an Edge shell. Users would operate apps and create documents by chatting with Copilot instead of controlling them directly. Although Microsoft might have shelved Aion, a video demonstration of the new Copilot update closely resembles certain aspects of it.

Notably, this latest push to embed Copilot in users’ systems follows an admission from Microsoft and Qualcomm that the Copilot+ PC brand has been abandoned, with the companies acknowledging that consumers simply don’t care about “AI PCs.” It remains unclear whether Home, Code, and Autopilot will be next in a growing trail of shelved AI initiatives such as Copilot+ PCs and Recall.

Oxford has let OpenAI use old texts from its Bodleian Library to train its AI models, according to internal papers seen by the Guardian. Ethan Penny and Dan Milmo broke the story on Saturday.

The papers say texts that OpenAI scanned at the library went into the firm’s training data.

Oxford made its deal with OpenAI public in March 2025. At the time, it said OpenAI’s tools would help scan rare texts so more students and scholars could read them. It did not say the texts would be used to train AI.

By June 2025, the Bodleian had sent OpenAI 125,000 scans of old PhD theses, the Guardian reported. They include theses written at European and US universities in the 19th and 20th centuries.

Notes from staff meetings, which the Guardian got through a freedom of information request, show some staff had doubts. They worried about harm to Oxford’s name and about the energy use of AI.

However, Oxford said the scans were small in scale, out of copyright and not exclusive to OpenAI. The library keeps the rights and will start to post the scans online in the next few months, a spokesperson said.

The spokesperson also said the AI training side had not been hidden. Scanning was Oxford’s main goal, but staff had been open that the texts would also be used to train models.

“With more than a billion people using this technology in everyday life, it’s important it reflects different cultures, histories and perspectives,” an OpenAI spokesperson told the Guardian.

Oxford is the only UK member of OpenAI’s NextGenAI group. Other members include Boston Public Library, Caltech, MIT and the University of Michigan.

The deal comes as AI firms buy printed books for slop-free training data, since the web is now full of AI-made text. Some buyers cut books apart to scan them, which has upset secondhand booksellers.

In August, 404 Media tracked a box of rare books to an Amazon site that scans and destroys books for AI. The Bodleian’s books stay whole under its deal, the Guardian reported.

Razer’s new Kiyo V2 Pro webcam uses Sony’s 8.3-megapixel STARVIS 2 sensor and costs $300.

Sony’s STARVIS 2 sensor also enables the headline feature here: 4K video capture at up to 60fps, a specification most consumer webcams still limit to 1080p or 1440p once frame rates climb above 30fps.

Razer pairs that sensor with a lens capable of an f/1.9 aperture, a wider opening than most webcams offer and one that should improve low-light clarity while producing a stronger background blur behind the subject.

Four decades after Walter Röhrl and Markku Alén drove Lancia’s Rally 037 to the 1983 World Rally Championship, a small Italian workshop in Cuneo has given that last rear-drive title winner a second life. Kimera Automobili, run by former rally driver Luca Betti from Villa Kimera about 100 kilometers south of Turin, limited the EVO37 to 37 cars. Number 018 now sits in Broad Arrow’s catalog as lot 158 for the Zoute Concours Auction on Friday, October 9, 2026, at Approach Golf in Knokke-Heist, Belgium.

Kimera used the same starting point as the original manufacturer and ran with it: the donor Lancia Beta Montecarlo center section was stripped, reinforced, and improved with a glossy new carbon-fiber shell. Behind all of this was a crew that knew what they were doing, including Sergio Limone, the man who had led the 037 and Delta S4 to great success, and Claudio Lombardi, Lancia’s former rally engine designer who had gone on to do the same for Ferrari in F1, both of whom gave the project their approval. The bodywork was then bolted to the chassis, and Italtecnica created a brand new 2.1 liter, 16 valve four-cylinder engine from the ground up. They preserved the 037’s supercharged configuration but added a turbocharger, resulting in a snappy 505 PS and 550 Nm of torque sent to the rear wheels via a fast six-speed Dana Graziano manual gearbox. The top speed is rated as 310 km/h, with a 0-100 km/h time of just 3 seconds, which is not bad. The vehicle features Öhlins double-wishbone suspension and Brembo carbon-ceramic brakes with four-piston calipers for stopping power.

• KEN BLOCK MINIFIGURE – The included Ken Block minifigure features a Hoonicorn hat and jacket, plus an extra helmet accessory for added play value

This vehicle left the workshop in March 2025 and has since traveled a total of 237 kilometers. Kimera’s Luci del Bosco paint job is a deep, rich metallic brown inspired by the old Lamborghini Miuras and Countachs. The gold wheels and beige leather upholstery over carbon fiber chairs give the cabin a relaxed feel, while the exposed gearlever is adorned with a wooden gear knob. LEDs light the road up front, and there’s air conditioning, ABS brakes, a digital rear view camera, and parking sensors to keep things polite without interfering with the exposed carbon, which is exactly what you want to see.

When this project first got off the ground in 2021, the asking price ranged between €450,000 and €480,000. Since then, the market has moved on, and Broad Arrow thinks that this particular specimen, number 018, is now valued between $950,000 and $1,150,000. Kimera has informed the Broad Arrow team that they will gladly assist with import and registration if the future owner is in Europe or the United States, and will even adjust the specifications to suit the buyer if they prefer something different. The tax issue is equally easy; because this is a VAT-qualifying sale, both the hammer price and the buyer’s premium are subject to tax.

The auction of this car will take place on October 9, 2026 as part of the Zoute Grand Prix Car Week, with a public viewing on the 7th and 8th and bidding beginning in the afternoon of the ninth. It’s a rare opportunity to own an original 037 Stradale that is this new and in this condition, and if that’s not enough, Kimera is still willing to re-spec the thing if the buyer has any other ideas.

Renault is bringing one of its most recognisable performance cars into the electric era with the Renault 8 Gordini Concept, a two-seat electric coupé inspired by the rear-wheel-drive icon that debuted in 1964.

The concept combines the visual language of the original R8 Gordini with a much more aggressive modern design. It has a low, wide stance, motorsport-inspired proportions and a 270hp electric motor. Renault says the project is part of its wider effort to revisit important models from its 128-year history through one-off creations.

Renault unveiled the concept on September 24 at Renault Carwalk, and it is scheduled to appear at the Paris Motor Show from October 12 to 18.

The classic Gordini gets a radically different electric makeover

The original Renault 8 Gordini arrived in 1964 with a 95hp rear-mounted engine and rear-wheel drive. It became known for delivering racing-inspired performance in an affordable package and served as a training ground for drivers including Jean Ragnotti. Its distinctive double white stripe eventually became a defining visual feature.

The new concept keeps the rear-wheel-drive character but replaces the petrol engine with a 270hp electric motor. Measuring 4.12 metres long, 1.88 metres wide and 1.27 metres tall, the coupé sits on 19-inch front and 20-inch rear wheels. Its proportions are deliberately closer to a modern rally car than the four-door original.

Renault has also carried several familiar details into the new design. The car gets six round headlights, squared-off wheel arches, a modernised Gordini badge and the iconic double white stripe. The stripe is no longer simply decorative, with Renault incorporating it into various structural and design elements of the car.

The design was created entirely in-house. More than 300 sketches were submitted during an internal Renault Design competition before two proposals were developed into scale models and combined into the final concept.

A two-seat EV focused on driving rather than practicality

Inside, Renault has taken a similarly minimalist approach. The cabin features brushed aluminium across the dashboard and controls, contrasted with Alcantara upholstery. Digital round displays echo the circular headlights, while bucket seats and a prominent stopwatch button reinforce the car’s motorsport-inspired character.

Renault describes the concept as part of its effort to connect its heritage with future design rather than simply recreate old cars. The R8 Gordini follows previous projects including the R17 electric restomod x Ora Ïto and Renault 5 Diamant.

For now, this remains a concept car, and Renault’s media page does not confirm that it will enter production. The company does say the concept will become part of its historical collection, alongside other vehicles and archive material at the future Renault Collections museum in Flins, expected to open in around 15 months.

So while you probably won’t be ordering one from a Renault showroom anytime soon, the electric R8 Gordini shows how Renault is imagining its performance heritage in an EV era.

PCB circuits are cool, but you know what is cooler? Terminator circuits that’s what! And what if the same material that makes Terminator circuits could also be used for smart heat sinks, flexible circuits, and self-healing material properties? Well, that is exactly what the lab at Virginia Tech’s VT MADE Lab has created, presented by Joel from [3DPrintingNerd].

So what does a Terminator circuit actually entail? Well, just like in Terminator 2, the circuits are made of liquid metal. Specifically, small drops of liquid metal alloy made of gallium and indium. These drops are contained within a matrix of PDMS polymer, which contains the magical liquid for conductivity, thermal and electrical . This makes a flexible and stretchy composite which can even self-repair when punctured or cut by bridging the

broken circuit with the liquid alloy. Having a polymer matrix allows this self-repairing property but also makes the material insulating by default, only allowing current to flow after selectively “popping” the matrix bubbles.

To create something with the composite material, you’ll find it similar to many other resin-based materials. You can pour, mold, and even 3d print a custom geometry. A short bake later and you get a solidified model made for whatever custom flexible circuitry you have in mind.

While this process requires chemicals, polymerization reactions, and a taste for liquid alloys, that shouldn’t stop you from trying out flexible electronics. For a more hands on method to flexible electronics check out this glove with circuits running throughout!
