Royal Mail is building a fleet of 500 drones to carry mail to remote communities all over the UK, including the Isles of Scilly and the Hebrides. The postal service, which has already conducted successful trials over Scotland and Cornwall, will create more than 50 new postal drone routes over the next three years as part of a new partnership with London company Windracers. Drones, or UAVs (uncrewed aerial vehicles), can help reduce carbon emissions and improve the reliability of island mail services, Royal Mail claims. They offer an alternative to currently-used delivery methods that can be affected by bad weather – ferries, conventional aircraft and land-based deliveries. They can also take off from any flat surface (sand, grass or tarmac) providing it is long enough.

A new phone app which offers users a free digital avatar is taking facial-recognition quality photographs and sending them to Moscow, prompting major concerns within the cyber security community. Tens of thousands of people have already uploaded their photographs to the servers of the New Profile Pic app in return to the free avatar. However, many will be unaware that the company behind the app, Linerock Investments, is based in an apartment complex overlooking the Moscow River, beside Russia's Ministry of Defence and just three miles from Red Square. Jake Moore, Global Cybersecurity Advisor, ESET Internet Security told MailOnline that people have to be incredibly careful when uploading photographs or personal data to a brand new website. He said: 'This app is likely a way of capturing people's faces in high resolution and I would question any app wanting this amount of data, especially one which is largely unheard of and based in another country.'

There's nothing more annoying than indulging in a delicious cheese board at a restaurant, only to forget what the varieties are in front of you are. But the days of scrambling to find the menu could be a thing of the past, thanks to a new app called Cheezam. Cheezam was inspired by the music-finding app, Shazam, and uses artificial intelligence (AI) to identify different cheeses from a single photo. Served in a simmering pot with a selection of dunkable ingredients, cheese fondue is without a doubt one of the most popular dishes among cheese lovers around the world. Now, the famous Swiss dish can be prepared, stirred up and served by a robot chef.

A senior director at Apple has quit his job in protest at the company demanding staff return to the office three days a week. Ian Goodfellow, the director of machine learning, is believed to be the most senior employee to resign so far as a result of the plan. On April 11, the company began mandating one day a week in the office - a requirement that rose to two days on May 2. By May 23, all staff had to be at their desks three days a week. A survey of Apple workers from April 13-19 found 67 percent saying they were dissatisfied with the return-to-office policy, Fortune reported. And Goodfellow, in his resignation note, said he would not do it.

A new wearable gadget that fixes to the arm can measure blood sugar and muscle fatigue at the gym and alcohol levels at the pub. Created in California, the prototype can continuously monitor three health stats – glucose, alcohol and lactate levels – either separately or simultaneously in real-time. About the size of three poker chips stacked together, it is applied to the skin painlessly through a Velcro-like patch of microscopic needles. These needles take readings from fluid under the skin and then sends the data wirelessly to a custom smartphone app. Researchers hope to commercialise the device, which could provide a single solution for diabetes patients in everyday life.

It may sound like something straight out of Star Wars, but Hyundai's planned'walking car' is a step closer to reality after the vehicle manufacturer unveiled a new $20 million (£16 million) development centre to expedite its arrival. The aim of the New Horizon Studio, which has opened in Montana in the US, is to build vehicles for future customers who want or need to travel over terrains which are challenging for conventional ground vehicles. It will focus on the development of Ultimate Mobility Vehicles (UMVs), including a car with legs that can simply walk over anything it struggles to drive over. The Elevate concept, which resembles the All Terrain Armoured Transport (AT-AT) walkers found in the Star Wars universe, combines a traditional wheel with a leg that unfolds for dangerous terrain.

Amazon's Alexa voice assistant is already a fount of knowledge on health topics ranging from the symptoms of chicken pox to how to relive a migraine. Now Amazon has teamed up with independent website Menopause Matters to provide answers to some of the most commonly asked questions around menopause. Alexa users in the UK can ask questions including'What treatments are available for the menopause?', 'What is perimenopause?', and'What are the benefits or risks of Hormone Replacement Therapy for menopause?' The news comes amid warnings that women going through the menopause are often mis-diagnosed with depression, because GPs do not know all the symptoms.

Elon Musk's Neuralink rival Synchron has begun human trials of its brain implant that lets the wearer control a computer using thought alone. The firm's Stentrode brain implant, about the size of a paperclip, will be implanted in six patients in New York and Pittsburgh who have severe paralysis. Stentrode will let patients control digital devices just by thinking and give them back the ability to perform daily tasks, including texting, emailing and shopping online. Although the implant has already been implanted and tested in Australian patients, the new clinical trial marks the first time it will be tested in the US. If successful, the Stentrode brain implant could be sold as a commercial product aimed at paralysis patients to regain their independence and quality of life.
