Scientists create the 'world's smallest violin'
A team of scientists have created the 'world's smallest violin' - which is tinier than a speck of dust and needs a microscope to see it!The micro-violin was created using nanotechnology by a team at Loughborough University.It measures 35 microns long and 13 microns wide - a micron is one millionth of a metre - for comparison a human hair is around 17 to 180 microns wide.Unfortunately the tiny violin is just an image and not a playable instrument, so it cannot be officially confirmed as the world's smallest violin, the university said.
The tiny violin was created to test the abilities of the university's new nanolithography system, which allows researchers to build and study tiny structures."Though creating the world's smallest violin may seem like fun and games, a lot of what we've learned in the process has actually laid the groundwork for the research we're now undertaking," said Professor Kelly Morrison, Head of the Physics department at Loughborough University."Our nanolithography system allows us to design experiments that probe materials in different ways – using light, magnetism, or electricity – and observe their responses."Once we understand how materials behave, we can start applying that knowledge to develop new technologies, whether it's improving computing efficiency or finding new ways to harvest energy," she said.
How did they make it?
To create the violin the researchers coated a tiny chip with two layers of gel-like material called a resist, before placing it under a nano-sculpting machine.Next the machine uses a heated, needle-like tip to "write" very precise patterns on the nanoscale - in this case a violin shape - in a process called thermal scanning probe lithography.After that a thin layer of platinum was poured into the carved out pattern to leave behind the finished piece.The whole process takes around three hours, but the research team's final version took several months to make, as they tested different techniques to get the best result.

Bournemouth students' gadgets to be showcased at design festival
A drinking aid for dementia patients, a robotic arm and a water pollution monitor are among the devices set to be showcased at a student design engineering University's Festival of Design and Engineering displays final-year projects created by students from the institution's design and engineering annual public exhibition will take place at the university's Talbot Campus on 27 and 28 year's entries also includes a hydro-powered unit that can monitor and transmit contaminants in rivers, as well as a handheld device that uses a static charge to pick up pet hair from clothing "The standard of the students' designs this year has been truly impressive," said Dr Yonghun Lim, deputy head of the university's department in design and engineering. "They're not just designing for assessment, they're designing with real purpose."Members of the public wanting to attend the festival can book free tickets through the university's website.

The Oxford roof that led the way in tackling climate change
Thirty years ago, a quiet suburban street barely noticed the start of a revolution being built on its doorstep.A house constructed in 1995 was the first in Britain to incorporate a solar roof and would set the agenda for domestic renewable this month, Energy Secretary Ed Miliband said the "vast majority" of new build homes in England will be required to have solar pioneers and figures from Britain's solar energy community have gathered to mark the 30th anniversary of the Oxford Ecohouse that led the way. Leading the way doesn't come first ever solar roof cost Prof Sue Roaf £28,000 to build. With no planning regulations at the time that addressed such a construction, the build proved particularly told the BBC: "To build this house, I had so much help from the industry because they bought into the vision."The idea that with the ordinary family home you could have a decent, ordinary life and have very little footprint on the planet."Despite the challenges the build was a success. The six-bedroom home produces 130kg CO2 a year per sqm. A comparable UK house produces 5,000kg CO2 a year per sqm."We were seen as living the ordinary life but just slightly differently," she said. "It was the solar life." The award-winning house gained international attention and inspired a new wave of climate architects."Sue was this slightly legendary figure," recalls architect and TV presenter Charlie Luxton, who was studying at the house brought photovoltaics (PV) - the process of converting light into electricity using semiconducting materials - and "low energy architecture to a very domestic setting", he said."The house could fit in on any street. I think that's what is so amazing about this project - that it could be everywhere, it should be everywhere."Every house built since then should have looked like this or at least had this level of thinking around PV and low energy and reducing the impact on planet and climate." Despite the revolutionary house being built in 1995 the idea of solar on domestic properties took a while to catch on."It wasn't until 2010 that the panels really became affordable," said Prof forward to 2025 and Energy Secretary Ed Miliband has said builders will be required to fit solar panels to the "vast majority" of new homes in England under changes to be published this rules will be included in the Future Homes Standard, which will detail a wider plan for improving energy efficiency and reducing carbon a government target of 1.5 million new homes to be built by 2029, insisting new homes have solar panels could make a significant architects like Alex Michaelis are worried such policies will not be said: "The fear always with these things is that in five years' time, with a change in government, they scrap it."This is one of my big things, that a lot of these things should not be party-politically based but there should be another body that says 'right, we set this in stone for 20 years'." One lasting legacy of the Ecohouse was the effect it would have on one of Prof Roaf's Roaf appeared as a schoolboy on Blue Peter when the programme featured the home. He gained the nickname "solar panel boy" but says that didn't put him off."I think my mum predicted it a bit before a few other people but I was actually inspired to get really involved in climate change campaigning," he said."I think both the solar house and being on Blue Peter, despite the nickname, did inspire me to go off in that direction."Standing on the balcony of the home she built, Prof Roaf reflected on what has been achieved as guests gathered for the anniversary party."I'm proud of what we built together because it wasn't me who bought the house, it was the team," she said. "And lots of them have come to celebrate."As for the running costs for the house?"Last month, for gas and electric without VAT and without standing charges, it was £7.56. I rest my case, your honour." You can follow BBC Oxfordshire on Facebook, X (Twitter), or Instagram.

White-tailed eagles thriving across the south-east England
White-tailed eagles have been mapped flying up to 100 miles (160km) a day over the South birds were released on the Isle of Wight in 2019 after being driven to extinction in the UK, and their daily explorations have taken them over Sussex and Kent, including the Elmley Nature Reserve on the Isle of birds, which are the UK's largest bird of prey with a wing span of up to 2.5m (8.2ft), are being monitored by the Roy Dennis Wildlife Ginnaw, lead nature guide at Elmley, said: "It's absolutely massive to have one on a reserve where I've been birding since I was small, it means a lot." Waterways and marshland have made Elmley a prime hunting ground, with the reserve saying seven different white-tailed eagles have visited over the last six latest, tagged as Eagle G603, has been especially active on the reserve this summer. 'I cried when I saw it' Natasha Marks, a birdwatcher, described the moment the eagle landed just 5m (16.4ft) away from her."Not to be dramatic, but I did cry when I saw it," Ms Marks said."It takes your breath away."Workers on the reserve said he dwarfed other birds of prey, such as red kites and marsh harriers."Having an apex predator like that here, it's an indicator of an underlying health in the wider eco system," Mr Ginnaw added. Some eagles have even been tracked as far afield as Scandinavia, however, the birds always return, having established the South of England as their Tim Mackerill, from the Roy Dennis Foundation, has been tracking these types of journeys for years and says habitat preservation will be key in the future."Kent and Sussex have been really important for the birds since we started the project," he said."These young birds are finding that habitat which is a really positive sign for the future." In 2023, chicks hatched in England for the first time in nearly 250 years at an undisclosed nest site in many of the recent cohort will not be ready to rear chicks for a while longer, since that typically starts at five to six-years old.
