Robots aren’t always the most delicate of machines when handling fragile objects. They don’t have the lightness of touch of humans. But that could be about to change thanks to a new development in smart materials.

Researchers have developed a method for weaving flexible fibers that can be controlled by magnetic fields. Not only can this be used for robot hands to pick up objects like soft fruits, and worms, but it can also be used in a range of other applications. These include gloves that provide a realistic touch in and breathable fabrics.

Creating a new smart fiber

In a paper published in the journal Nature, researchers detail how they created their smart textile, which can bend, stiffen or change its surface texture on demand. First, the team mixed tiny, soft magnetic particles (carbonyl iron) into extremely thin, flexible fibers of a polymer, LDPE (low-density polyethylene).

To overcome the challenge of making a fiber that is both thin and packed with , the researchers used a process called melt spinning. This high-speed technique allowed them to create fibers just 57 micrometers in diameter.

The next stage involved twisting seven of the fibers together into a helical yarn. The importance of this shape is that it can respond to a from any direction. This is what truly sets it apart from other .






Instead of being limited to simple “on/off” reactions (like heating or stiffening when a voltage is applied), which is called scalar control, the helical shape provides the material with directional control. That means it can respond to the strength and direction of the magnetic field, which allows more sophisticated movements.

“Our work provides insights into stimuli-responsive fibrous materials, elevating them from scalar to sophisticated vector control, heralding an era of smart textile innovation,” wrote the researchers in their paper.

Real-world applications

The team created two types of fabrics from the yarn. A woven textile that is best for bending and stretching, and a cut-pile fabric that looks and feels like a soft brush. From the woven textile, they made a kind of fabric patch that automatically opens and closes tiny ventilation slits in response to a magnetic field cycling on and off. This could be used to manage sweat and heat instantly.

With the cut-pile , they built a soft robotic gripper. Because the thousands of magnetic fibers can individually stiffen and mold around objects, the gripper enables robots to safely and gently pick up delicate objects.

Additionally, the researchers made a virtual reality haptic glove. When you grab a virtual object, a remote magnetic field stiffens the fibers or presses them against your skin to simulate real-world tactile sensations.

Next up for the team is to improve the materials for commercial use, ensuring they are durable and safe for comfortable, everyday clothing.

Anthropic Plots Major London Expansion

Anthropic Plots Major London Expansion


Anthropic is moving into a new London office as it seeks to expand its research and commercial footprint in Europe, setting up a scrap between the leading AI labs for talent emerging from British universities.

The company, which opened its first London office in 2023, is moving to the same neighborhood as Google DeepMind, OpenAI, Meta, Wayve, Isomorphic Labs, Synthesia, and various AI research institutions.

Anthropic’s new, 158,000-square-foot office footprint will have space enough for 800 people—four times its current head count—giving it room to potentially outscale OpenAI, which itself recently announced an expansion in London.

“Europe’s largest businesses and fastest-growing startups are choosing Claude, and we’re scaling to match,” says Pip White, head of EMEA North at Anthropic. “The UK combines ambitious enterprises and institutions that understand what’s at stake with AI safety with an exceptional pool of AI talent—we want to be where all of that comes together.

UK government officials had reportedly attempted to coax Anthropic into expanding its presence in London after the company recently fell out with the US administration. Anthropic refused to allow its models to be used in mass surveillance and autonomous weapon systems, leading to an ongoing legal battle between the AI lab and the Pentagon.

As part of the expansion, Anthropic says it will deepen its work with the UK’s AI Security Institute, a government body that this week published a risk evaluation of its latest model, Claude Mythos Preview. According to Politico, the UK government is one of few across Europe to have been granted access to the model, which Anthropic has released to only select parties, citing concerns over the potential for its abuse by cybercriminals.

The increasing concentration of AI companies in the same London district is an important step in creating a pathway for research to translate into AI products, says Geraint Rees, vice-provost at University College London, whose campus is around the corner from Anthropic’s new office.

“This cluster didn’t emerge from a planning document. It grew because serious researchers and companies understand that proximity isn’t a nice-to-have,” he said last month, speaking at an event attended by WIRED. “That’s how the innovation system actually works. It’s not a clean, linear transfer from lab to market. It’s messier, richer, more human than that.”

LG’s High-End Soundbar System Makes My Living Room Feel Like a Home Theater

LG’s High-End Soundbar System Makes My Living Room Feel Like a Home Theater


Setup was relatively quick and painless. You just have to unbox four speakers, a soundbar, and a subwoofer, attach their power cables, and plug in everything. Pairing happens through the LG ThinQ app, which allows you to set up the Sound Suite system and tune it to exactly where you’re sitting in the room using your cell phone’s microphone.

You can also set up each speaker to play music and group it with any other LG smart speakers you might have around your home, like the more affordable $250 M5 bookshelf speaker, to create a whole-home system.

Once all the components were synced, I plugged the soundbar into the C5 OLED via HDMI, and was able to easily control everything via the TV remote’s volume and mute buttons. More in-depth settings had to happen in the app, but if you’re anything like me, this won’t become a regular chore. You’ll set it how you like it once and move on. While the pairing functionality with the LG TV was nice, it’s not required–the eARC port lets the Sound Suite work perfectly with any modern TV.

The bar itself runs the show, with a black-and-white display on the far left that shows your mode and volume, among other settings. In the center of the bar and below each speaker, an LED light strip that also shows you the volume when you change it, which is a nice touch.

The sound of the LG Sound Suite is full and cinematic, thanks in no small part to the extra dedicated speakers. Most competitors lack front left and right, simply opting to use the soundbar for these channels. As such, the width and breadth of the soundstage were bigger than most competitors I’ve tried, with only Samsung’s flagship HW-Q990F as a real contender. Even the Samsung lacked the lower-frequency audio quality that these LG speakers provide.

Cyber Essentials closes the MFA loophole but leaves some organisations adrift | Computer Weekly

Cyber Essentials closes the MFA loophole but leaves some organisations adrift | Computer Weekly


On 27 April, the government backed security certification scheme, Cyber Essentials v3.3, takes effect and multi-factor authentication (MFA) becomes a pass-or-fail requirement for the first time.

If a cloud service your organisation uses offers MFA and you have not enabled it, you fail. No discretion, no partial credit, no route to remediate inside the assessment cycle.

This is the right call. I want to say that clearly, because what follows is a problem with the implementation, not the policy. MFA is the single most effective control against credential-based attacks, and the scheme has needed to stop tolerating its absence for a long time. The National Cyber Security Centre (NCSC), part of GCHQ, which developed Cyber Essentials and certification company, IASME have got this decision right.

But in the assessments we have conducted this year, I have seen two organisations that will hit a wall on 27 April, and I do not think they are unusual.

Train company could not deploy MFA

The first is a train operating company in the South East. Station operations rooms run on shared terminals where staff rotate through shifts in time-critical conditions. A transport union raised formal concerns that MFA would introduce delays at the keyboard that could affect train operations and, in their view, the safety of train movements.

The company listened and chose not to enable MFA in those environments. Under v3.2 they passed, with the relevant questions marked as non-compliant but not fatal. Under Cyber Essentials v3.3 they will fail.

Charity run by volunteers faces MFA hurdle

The second is a nationally known charity with hundreds of high street shops. The shops are staffed largely by volunteers many of whom work a few hours a week, and staff turnover is high.

The cost and management overhead of enrolling every volunteer onto MFA, using personal phones they may not have and authenticator apps they would not keep, was considered prohibitive. So MFA was never switched on. Same story: they passed under v3.2. Under v3.3 they fail.

Neither of these organisations is ignoring security. Both made considered decisions based on how their people actually work. The problem is not that they do not want to comply. It is that the standard toolkit of MFA methods, including SMS codes, authenticator apps on personal phones, and push notifications, does not fit a six-person shared terminal that has to be available in seconds, or a volunteer workforce that changes every week.

FIDO2 could offer solutions

The frustrating part is that there is a solution, and it is already proven in healthcare, manufacturing and retail. FIDO2 authentication delivered through NFC badge-taps lets a staff member authenticate in under two seconds: tap a badge, enter a short PIN, session opens.

It satisfies the MFA requirement by combining possession of the badge with knowledge of the PIN. It is faster than typing a password. Crucially, it is compliant, because each badge is enrolled as that individual’s unique FIDO2 credential, so the Cyber Essentials requirement for unique user accounts is met. Shared keys or shared PINs would not work. Individual badges do.

Need for better guidance

v3.3 explicitly recognises FIDO2 authenticators and passkeys as valid MFA methods. The compliance path is clear. What is missing is anyone telling the organisations most affected that this path exists.

That is the gap that must close. The NCSC and IASME have made the right policy decision; the scheme would be weaker without it.

 But implementation guidance for shared-terminal, shift-based and high-turnover environments is thin, and these organisations are running out of time to find their way through it. Many of them hold Cyber Essentials because it is required for government contracts or in their supply chains; losing certification has a direct commercial cost.

The answer is not to soften the requirement. The answer is to make sure no one fails for lack of information about how to meet it.
