A TOP Dyson designer has revealed exactly how fast to move your vacuum cleaner – and going slower can actually save you time.
It turns out that racing around your house isn't necessarily the best way to get the cleaning out of the way quickly.

Vacuuming an entire house can be a bit of a nightmare, especially if you've got loads of furniture, carpets, and a dog or cat.
So going fast can be tempting now that vacuum cleaners are often wireless and lightweight – just look at Dyson's impossibly thin new PencilVac.
SPEED TEST
I took a trip to Dyson 's Oxfordshire campus where I heard from Dyson designer Jonny Gray, who revealed the exact speed you'll want to be moving your vacuum cleaner.
"To be exact, about 0.3 metres a second is probably where you want to be in terms of speed," Jonny explained.
That's a 30cm ruler, so if you imagine moving across one of those every second, you're getting it right.
"I'm sorry to say that the slower you go, the cleaner your floors will be," Jonny said.
Of course, he warned that you can also end up going too slow.
The Dyson design whiz said you'll get "diminishing returns the more you go over it".
So it's important to not go too slow or fast – and stick to the 30cm rule.
"The IEC standards that we get are 0.5 metres a second," Jonny, Senior Design Manager at Dyson, told us.

"But we have demonstrated that you get around 100% pick-up over the course of three passes with 0.3 metres a second speed."
If you rush around, your vacuum cleaner will end up missing bits.
And if you go too slow, you're simply wasting time – and it won't be worth the wait.
FOOD FOR FLOORS
Jonny, who works on vacuum cleaners at Dyson's gigantic Malmesbury campus, spends time trying to pick up all manner of difficult debris.

And he also told The Sun that Cheerios are one of the trickiest things for a vacuum cleaner to collect due to their size.
But he warned that US-style Froot Loops are even trickier to collect.
Dog biscuits are also difficult for vacuum cleaners to pick up, Jonny revealed.
But the brainy Dyson designer explained that if you follow the 30cm rule, you should be able to get a "100% pick-up" rate – even during a nightmare Cheerio spillage.
Dyson's Lab includes a cupboard filled with different materials for testing with its vacuum cleaners.
That includes porridge oats, British and even American rice, sugar, cotton wool, and cat litter.
And they even have Japanese sushi rice and tea leaves, to make sure that the vacuum cleaners they flog to Japan are up to snuff.

Open Banking Won't Work Without Trust. Here's How We Enable That.: By Mathieu Altwegg

Open banking isn't just a regulatory shift - it's a generational opportunity. For the UK, one of the most digitally connected economies in the world, it offers a pathway to make managing money simpler, smarter, and more rewarding. It holds the promise for consumers to move money instantly, access better financial tools, switch providers effortlessly, and view their entire financial lives in real time. That future is no longer theoretical - it's here and now is the time for it to scale, but only with the right catalyst. From in-game purchases to managing cross-border transfers, Open Banking is already enabling faster, more flexible money movement. For the consumer, convenience is king. In 2023 alone, 70% of all UK online purchases were made via mobile phones, while over 90% of in-store transactions used contactless. The shift in consumer behaviour is clear: people expect seamless, secure, and intuitive ways to pay – if they trust it they will use it. Yet adoption in the UK remains uneven. Many consumers are still hesitant to embrace open banking as a way to pay - often due to concerns around protection, limited awareness, and inconsistent user experiences. The underlying technology is strong, but trust has yet to catch up. And trust isn't built overnight - it's earned through consistent focus, sustained investment, and a relentless commitment to putting customers first. It goes beyond fraud prevention; it's also about how issues are handled when things go wrong. If a consumer makes a payment to a business and doesn't receive the goods or services, they need the reassurance that they'll be reimbursed. The same goes for merchants – while cost savings and speed are attractive, many have proved reluctant to embrace pay by bank without the systems in place to smoothly handle disputes. Why would they risk turning a hard-won customer into a net cost if something goes wrong? These are the kinds of safeguards that will turn curiosity into confidence, and that's the gap we need to close. Simplicity and Control will Drive Trust and Uptake At its heart, open banking is about giving people more choice. Whether it's streamlining loan applications, enabling one-click checkout, or bringing together multiple accounts into a single, real-time view - open banking empowers consumers to manage their finances on their own terms. Recurring payments are a clear example. Today, Direct Debit dominates but brings friction: delays due to failed payments, manual work to match payments and records, and user visibility. Variable Recurring Payments (VRPs), enabled by open banking, offer a compelling alternative: real-time availability of funds, enhanced transparency, and greater user control. That translates into fewer payment failures and more predictable cash flow for businesses and consumers alike. But it is account-to-account (A2A) payments backed by a trusted provider with additional protections and features that will cement open banking as a go-to mechanism. Open banking unlocks powerful consumer features: tracking subscriptions and bills in one place, setting limits, and stopping unwanted charges. These convenient experiences will build trust, but consumers are both savvy and cautious; aware that risk still exists. They will need the presence of a trusted independent player in the payment process who can provide them protection. Collaboration Is the Key to Change The opportunity is enormous. Innovate Finance estimates that growing the UK's fintech ecosystem - where open banking is foundational - could unlock £328 billion in value over the next five years. But realising that value requires collaboration and consensus. No single organisation can do this alone. It will take coordinated efforts across banks, fintechs, payment providers, and policymakers to deliver consumer-friendly infrastructure that connects easily and works across providers. That's why we support collaborative A2A solutions that are open, secure, and built to scale - because a rising tide lifts all boats. Businesses Needs to Be Part of the Open Banking Story While the consumer opportunity is front of mind, the potential for business-to-business payments is just as transformational. Open banking can modernise how companies - from SMEs to large enterprises - manage cash flow, settle invoices, and access working capital. We should be pushing the boundaries of what's possible, not just for consumers, but for all users of the financial system. A UK Leadership Opportunity The UK has a proven track record of leading in payments innovation - from contactless adoption to the rise of challenger banks and embedded finance. The next leadership opportunity lies in scaling open banking, not just by improving the technology behind the scenes, but by embedding usability and trust across the ecosystem. The policy landscape is moving in the right direction. In her 2024 Mansion House speech, Chancellor Rachel Reeves reaffirmed the government's support for the development of open banking - signalling alignment between regulators and industry. For all these reasons, we're working with partners across the financial ecosystem to unlock the full potential of open banking. We've developed open-access A2A capabilities that support both consumer and business use cases - offering trusted, secure rails that complement card and other payment options. But we're not here to go it alone. We want to work with industry and policymakers to ensure that open banking delivers on its promise - for everyone.

A wander in the beeches is a religious experience

The nature reserve of Burnham Beeches, a couple of miles above Slough's trading estate, is justly famed for its numerous and titular Fagus sylvatica. George Orwell was an admirer; in Keep the Aspidistra Flying, 1936, Gordon and Rosemary, on a day out from their drearisome London life, fall into extravagant happiness seeking a suitable epithet for the beech trees there: 'Both agreed that beeches look more like sentient creatures than other trees. It is because of the smoothness of their bark, probably, and the curious limb-like way in which the boughs sprout from the trunk.' The historic pollarding — pruning at head height — of Burnham's beeches has produced admittedly animalesque trees, but sometimes of writhing agony. Burnham's beeches haunt the mind. They possess soul too, since to enter a summer beech wood is to step into a cathedral: the extraordinary estival density of the foliage produces a mystried gloom. The other way around, of course, since to enter a cathedral is to enter a beech grove; the Gothic architects of our great houses of prayer were inspired by the beech, with its numinousness and elegant ability to buttress the roof of the heavens. • Rain at last but age-old patterns are moving fast There are other wonders at Burnham, such as wood ants, of which the reserve has 500 colonies. Each domed metre-high nest possesses 250,000-plus inhabitants. If ants have a reputation for industry, their cleverness is insufficiently praised. Wood ants lay the grass-and-twig thatch roof on the formicarium in such a way that it acts as a solar panel. Temperature inside the domed abode is regulated by ants opening and closing tiny holes in the roof. Humans call this sun-utilisation 'sustainable eco-living'. There are six species of British wood ant, but only three are commonly encountered: the northern hairy, Scottish and southern. Burnham's ants are the latter sort, Formica rufa. Reddish, but with a jet-black abdomen. Workers reach 10mm in length, queens a stately 12mm. Their 'flying season' begins in late June, when winged males and queens emerge en masse and take to the air to mate and form yet more colonies. • How a plague of 'mirror bacteria' could destroy all life on Earth Common broomrape is a parasitic perennial, entirely lacking chlorophyll; on first poking through the ground it takes an unseemly mauve hue but soon turns brown, at which point it looks akin to an intricately carved stick. Orobanche minor rarely appears in the singular, coming in platoons. The veronica bush in our garden is hosting 80-plus broomrapes packed under its shade, with one specimen measuring 61cm. In the bush's twilight zone, the broomrapes present an unearthly spectacle: they have no proper dirt-seeking roots so they suck nutrients out of the veronica's uppermost roots via their 'haustoria', special penetrating tubes. When not invading gardens, common broomrape succours on clovers, although there are numerous sub-species, including maritima. This latter is vampiric on sea carrots. And the reason for the unattractive name of this unattractive plant? Gerard's Herbal of 1597 notes the plant, or another close member of the Orobanchaceae, growing 'unto the roots of broome', the gold-flowered shrub. The old country names of 'devil-root' and 'hell-root' for Orobanche minor indicates that its infestation of clover in the meadow is historically trying for farmers. Last week in the Charente, France, my 4km cycle rides to town to 'faire le shopping' were traffic-free, except for pine martens. On one occasion a pair ran along the other side of the road, keeping perfect lane discipline, but mostly the cat-sized mammal ran across the tarmac in front of the bike's wheels. This was in broad daylight. A member of the weasel family, Martes martes is weaselly recognisable: in addition to the sort of glossy chestnut hair one associates with shampoo adverts, it possesses a stand-out creamy-orange bib. The exact shape and extent of the bib is particular to each individual. In Britain, the pine marten is rare and restricted to the forests of Scotland, northern England, north Wales and small, partly reintroduced populations in southwest England. The mustelid's French cousin is seemingly carefree about the 'pine' designation, or indeed a definite affinity with woodland. The stretch of 'La France Profonde' for my shopping trips consisted of sunflowers and wheat fields. A sole line of shimmering poplar trees along the brook seems sufficient treeness to satisfy the marten's need to climb and nest above ground, thus beyond the jaws of a predator even bigger and badder than itself: Monsieur Renard.

National Star students take part in 24-hour wildlife survey

Students at a special educational needs college have teamed up with ecologists to find and identify the species found on their 80-acre Star College near Cheltenham in Gloucestershire took part in this week's "BioBlitz" with Gloucestershire Wildlife Trust to assess biodiversity on are now working on strategies to support nature and try to boost the numbers of vulnerable student said she had learned how small changes can make a big difference to wildlife. The students found that hedgehogs, rabbits, deer and foxes call the college's grounds home, as well as a huge variety of insects, including many Adamou, a community action officer with the wildlife trust, said the event aimed to give students autonomy to decide how best to help the species they found."My mission in Gloucester is to make sure everyone has the opportunity to do something for nature - to build a relationship, to take meaningful action, to do something that makes nature more important for them and therefore protect it," she said. "It's so easy to just say 'this habitat needs this, this is what needs to happen' - there's no co-ownership."Students spent the weeks leading up to the event learning to identify different species and also considering ways to help them, such as building hedgehog student, Isabella, said: "Hedgehogs are vulnerable to extinction and we need to look after them, but small changes can make a big difference."Elaine Hodgin, the college's sustainability lead, said staff and students were working to reduce the site's carbon footprint. "It's also about educating the learners about what they can do with regards to climate change," she Star now plans to hold the event annually.
