Firefighters are spending a third day tackling a major wildfire which has led to evacuations in the Cairngorms. The blaze started in heathland at Ryvoan Bothy, near Nethy Bridge, late on Wednesday morning and had spread across 3.7 miles (6km) by Thursday afternoon. A number of homes and businesses, including campsites and a ski resort in the Glenmore Forest Park area have been closed and evacuated as a safety precaution. A helicopter joined the firefighting efforts on Thursday night. Nine fire appliances and specialist resources remained at the scene on Friday morning.

New photograph marks Queen's 79th birthday A new photograph of Queen Camilla has been released to celebrate her 79th birthday. The picture, showing the Queen in a long blue dress, was taken last month in the state drawing room of Hillsborough Castle in Northern Ireland. Buckingham Palace said the Queen was marking her birthday with a renewed commitment to supporting children's literacy, with the announcement that every year 6 and P6 child across the UK will be gifted a special edition of the book Impossible Creatures by Katherine Rundell this Christmas. Much of the Queen's public work supports reading and literacy, including the creation of the Reading Room charity designed to promote the benefits of reading. Rundell's book will be distributed to children through schools and libraries.

Models wearing garments created by Cap_able, which which markets them as making AI recognition more difficult. 'Adversarial clothing': are garments designed to confuse facial recognition systems about to go mainstream? As facial recognition technology is rolled out across Britain's public spaces, a new generation of designers say privacy could be the next big fashion trend. Companies have started incorporating "adversarial patterns" in their garments - carefully designed arrangements of shapes, colours and repeated motifs said to exploit weaknesses in some computer vision systems.

Einstein's field equations, Newton's universal law and artificial intelligence are among the subjects of Laidlow's ambitious orchestral works R obert Laidlow is as at home in the realms of science and technology as he is in the world of classical music. As this NMC debut album demonstrates, his intricate, wildly imaginative work is eminently approachable, even if the core concepts are highly complex. Warp, a terse, 12-minute piano concerto, proposes a musical solution to Einstein's field equations as the intrepid Joseph Havlat boldly goes where no pianist has gone before amid the distorting fabric of orchestral space-time. Strident orchestral lines spiral ever upwards, stretching instruments to their limits, while the piano maintains its course towards a serene conclusion. Handsomely recorded, the BBC Philharmonic and Vimbayi Kaziboni offer vibrantly detailed support. The Piatti Quartet plays Gravity, a harmonically unstable if slightly verbose homage to Newton's universal law that at one point pitches the players into the musical equivalent of a black hole.

A meningitis B (MenB) vaccination programme targeting young people and university students in Northern Ireland will roll out from 31 July, NI's chief medical officer has said. It follows an outbreak in England earlier this year, in which two people - a university student and a sixth-form pupil - died. The two-dose vaccine will be offered to those deemed most at risk from the infection, including Year 14 students and under-25s starting university or a Higher Education institution for the first time this autumn. MenB is a bacterial infection that can cause serious, life-threatening illness including inflammation of the lining of the brain and blood poisoning (sepsis). It is spread by close contact such as kissing, sharing vapes or drinks, or living in close quarters - like student accommodation - with a person who has the disease.

'Mind-blowing' ancient bones discovery sparked by family holiday To play this video you need to enable JavaScript in your browser. A family holiday sparked a series of remarkable archaeological discoveries which one expert says could change what is currently known about Britain's prehistory. John Bolton, an archaeologist, was visiting the 11th Century Pembroke Castle in 2010 when he heard there was a cave beneath it. His interest grew when he discovered that the cave, known as Wogan Cavern, showed little signs of previous excavation - so he badgered Dr Rob Dinnis, from the University of Aberdeen, to take a look. Small digs have since uncovered extremely rare evidence of early humans and animals - including the bones of a hippopotamus which roamed Wales 120,000 years ago.

China has hit out at the nationalisation of British Steel, saying it firmly opposes and is strongly dissatisfied with the British government's decision. On Thursday, the UK government said that taking the loss-making firm into public hands would protect jobs and safeguard a vital national capability. The UK took control of British Steel's operations in Scunthorpe last year, though it was still owned by China's Jingye Group, limiting the government's ability to steer its future. China's commerce ministry said on Friday that the moves seriously infringed upon Jingye's legitimate rights and interests and severely undermined the confidence of Chinese companies investing in the UK. It also called on Britain to faithfully fulfil its obligations under the China-UK Bilateral Investment Treaty. Disregarding Jingye's significant contribution to the UK economy and society, the British side forcibly took control of the company in the name of national security, the ministry said.

This remarkably vivid home projector has deep inky blacks, without a five-figure price tag. Premium home theater projectors often come at premium prices, usually north of $10,000. The Xgimi Titan Noir Max is different. It's priced at $5,999, well under five figures, but it supports IMAX Enhanced mode and has outstanding picture quality, a 10,000:1 native contrast ratio, 7,000 lumens brightness, and a unique dual intelligent iris system that makes on-the-fly adjustments. Even though Xgimi has been around for more than a decade and is known for affordable home cinema models, the company ran a Kickstarter campaign for the high-end Titan Noir Max home theater projector and raised $19 million.
