Mysterious ‘alien-like' sea creature that can devour prey 3 TIMES its size is found on UK beach
"Sea mice" are marine worms with a furry appearance that are unlike anything else in the sea and can grow up to six inches long.

Simon Parker recently discovered one of the creatures on a Welsh beach prompting discussion on social media due to its curious appearance.
Compared by many to a fossil and even an "alien", the sighting has left many admitting that they had never seen anything quite like it.
Simon was left flabbergasted after discovering one of
the six-inch long creatures at Pensarn Beach,
Conwy, and turned to tech to determine exactly what it was.
Uncertain of its identity and intrigued by its green-flashing fringe he used Google Lens to determine it was a sea mouse.

"I found it at the water's edge just after low tide," he told Wales Online.
"Unfortunately it didn't appear to be alive. The sea mouse was approximately five or six inches long with brightly coloured bristles down the sides."
Sea mice are not a rare species but their sightings are infrequent, often being washed ashore during stormy weather or left behind by exceptionally low tides.
Another of them was located in March on Oxwich beach in Swansea.

Although it has a tendency to bury itself head-first in the sand this creature boasts a remarkable set of skills.
Its spines typically have a deep red sheen, serving as a warning to potential predators.
However when exposed to light, they flash blue, green, and gold, giving the worm a dazzling, iridescent appearance.
This phenomenon, known as pseudo-birefringence, is the only known example of "photonic engineering" in nature, says the WT.
The spines process light with nearly 100% efficiency – a necessity in the dimly-lit depths of the sea.

Some researchers believe that this unique ability could lead to the development of new communication technologies.
Beauty and the beast
While this creature is technically a marine worm, it is believed that the name "sea mouse" originated from its resemblance to a bedraggled mouse when washed up on shore.
Its Latin name, Aphrodita aculeata, is equally peculiar. While aculeata translates to "spiny" the genus name Aphrodita refers to the ancient Greek Goddess of Love – allegedly due to the worm's resemblance to female genitalia.
The sea mouse is an active predator that feeds on small crabs and other worms and is capable of consuming prey over three times its own body length. Every now and then they can be seen wriggling across the sand – a sight that invariably unnerves beachgoers.

Three-year trips to Mars in 2030s, spaceship holidays & budget rocket trips to race around Earth, UK space hero predicts
SPACE isn't just for scientists and celebs – it'll be a hot holiday destination and will offer a shortcut to slash flight times too. They're just some of the predictions from British space hero Tim Peake, who sat down with The Sun for a chat about our off-Earth future . 9 Space hero Tim Peake was Britain's first European Space Agency astronaut Credit: Getty 9 Peake, who hails from Sussex, spent half a year on board the ISS Credit: Publicity - Getty Tim, 53, spent about 186 days in space, returning from the ISS on June 18, 2016. But when humans start making the first trips to Mars in the next decade or so, they'll be in space for a lot longer – potentially for three years. It sounds nightmarish, but Tim says we've done it all before, hundreds of years ago. 'A lot of people today forget about what we used to do in terms of exploration, the hardships, the torture, the kind of risk that was taken,' Tim told The Sun at Goodwood Festival of Speed's Future Lab earlier this month. Read more on space 'And in the early 1800s, nothing was thought about disappearing off on a three year expedition. 'That was pretty standard if you were in the Royal Navy. You say goodbye to your family and your mum. 'You say goodbye. You don't really know where you're going or what you're going to be doing, but you're just going to be away for a long time. 'So when I talk to people about in the mid 2030s, we're going to be on a three year mission to Mars and they kind of have this shock and horror that, well, that's so long, you'll never get people to go away for that long. Most read in Science 'Well, you will. We've done this before. 'It's only in the last 150 years that it hasn't been normal to have a three year expedition away, finding new lands and discovering new things. Nasa reveals mesmerising footage of Northern Lights from ISS 'And we're going to kind of go back into that kind of mindset. It's just that it won't be on Earth. It will be out into space.' Nasa hopes to make manned trips to Mars as soon as the 2030s, although no firm date has been set. But whenever those first visits happen, the astronauts will likely be a lot more comfortable than explorers of the past. 'The levels of resilience and self-sufficiency they needed was unbelievable. I mean, again, when we do Mars, the crew will have enough food, they'll have enough water, they'll have enough life support,' Tim said. 9 Six-month trips to the ISS will be nothing compared to a three-year Mars trek Credit: Getty He continued: 'We've mapped the surface, we'll have habitation modules for them. 'So it'll probably be a lot more comfortable than it would be setting off on endurance or HMS Wager back in the day.' SPACE STAYS For now, going to space is largely the preserve of professional astronauts, celebs and the ultra-wealthy. But in the future, Tim thinks that Tim credits Musk's company SpaceX with making space travel a lot cheaper. 'They've brought the cost of getting to space down so much, which is really exciting. 'Because that opens up whole markets of things you didn't think were possible because they were cost-prohibitive five or 10 years ago, that are now economically viable. 'So that's really exciting, but SpaceX is just the Uber that gets you there and back. 9 A return trip to and from Mars will be long and arduous – but Tim says explorers will be more than capable of surviving the time away from home Credit: Getty 'What's even more exciting is: now what can you do when you're up there?' Tim tells me that space tourism has been around for a long time – but it's becoming more frequent. And that's a trend that will only grow with time. 'It's part of the democratisation of space,' Tim told The Sun. 'I think fast-forward 100 years and there'll be an awful lot of people going to space for a variety of different reasons. 'Some for science, some for exploration, some for entertainment, and some for a different holiday.' Unsurprisingly, Tim reckons that we'd all be better off if we'd taken a trip to space. He says it gives you a different view of the world – and not just literally. WHO IS TIM PEAKE? Here's what you need to know... Major Tim Peake is a British Army officer and astronaut He is the first British astronaut with the European Space Agency He's also the sixth Brit to go aboard the International Space Agency Peake was born in Chichester, West Sussex in 1972 In 1990 he attended the Royal Military Academy Sandhurst In 1992, he joined the Army Air Corps Then two years later Peake became a qualified helicopter pilot Peake left the army in 2009 to follow his dream of becoming an astronaut He beat more than 9,000 applicants for one of six spots on the ESA's astronaut training programme He had to endure a rigorous selection process that tested his intellect and fitness Peake was launched to the ISS on December 15, 2015 In April the next year, he ran the 2016 London Marathon from the ISS treadmill And in June 2016, he finally returned to Earth, landing in Kazakhstan on a Soyuz descent module During his time in space, Peake completed roughly 3,000 orbits of Earth Picture Credit: Getty Images 'I think it is amazing. The more people that can witness Earth from space – Earth would be a better place. Definitely,' Tim said. 'People would have perhaps have a different perspective when they're making decisions. 'Having kind of seen how we all share one planet. And it looks fairly remote and isolated from space.' So your Moon vacation in 2065 won't just be a relaxing break, but an upgrade for your mind too. 9 Space tourism could be big business – Jeff Bezos' Blue Origin has already shown off concepts for an Orbital Reef space station that could host holidaymakers Credit: Blur Origin 9 Travellers could pay large sums of money to enjoy off-Earth hols Credit: AFP EARTH, VIA SPACE Of course, space tourism isn't the only way rockets will help your holidays . Tim reckons it'll make moving around Earth easier too. Holidays to the Moon will involve blasting off from Earth and landing on the rocky satellite. But that's not the only version of going space – you can also take suborbital flights that skim space, and descend back to Earth. 9 'Some of those missions they're launching, say, from New Mexico . They're going up and landing in New Mexico ,' Tim explained. 'Having been into space, well, there's no reason why you couldn't launch in New Mexico and land in Paris on that same kind of mission. 'And that could be a new form of suborbital transportation that becomes very popular in the future.' It sounds nightmarishly expensive – and it probably would be at the start. 9 Tim Peake was the Randox Future Lab Ambassador at this year's Goodwood Festival of Speed Credit: Nicole Hains / Goodwood Festival of Speed But eventually, Tim thinks, we could see the cost come down. Speaking to the astronaut, I joke that we could see Ryanair-style budget flights that only cost a tenner. 'I mean, if you if you went back to those early 1920s, 1930s transatlantic carriers, you would have found very wealthy people on board traveling in relative luxury ,' Tim told me. 'And if you'd have said, you know, in 100 years time, we're going to have the EasyJets and the Ryanairs – a mass global transportation at the same cost of a train ticket – they would never have believed it. 'So you never know what we can do with future changes in technology.' 9 The Sun's tech editor Sean Keach sat down with astronaut Tim Peake for a chat Credit: Sean Keach

Scientists to launch mobile app to detect potato blight at early stages
Potato blight, one of the world's most devastating crop diseases, could soon be detected using mobile phones, thanks to a new app being developed by Welsh scientists. Spearheaded by a research team at Aberystwyth University, the DeepDetect project aims to develop a mobile phone app that uses artificial intelligence to provide early warnings of diseases in potatoes. Potato crops are highly susceptible to diseases caused by pathogens such as fungi, bacteria, viruses, and nematodes. Late blight, caused by Phytophthora infestans, can wipe out entire fields, and lead to enormous costs and food shortages. It is responsible for 20% of potato crop losses and €4bn in economic losses worldwide. Traditionally, disease detection in crops has relied on manual inspection, a method that is time-consuming, expensive, and often subjective. DeepDetect aims to change that by harnessing the power of machine learning to deliver accurate diagnoses directly to farmers' smartphones. Dr Edore Akpokodje, a lecturer in computer science at Aberystwyth University, said: 'Our goal is to empower farmers with a tool which is not only scientifically robust but also practical and easy to use, and which delivers instantaneous, location-specific disease forecasts straight to their phones. "By integrating farmer feedback from the outset, we will ensure that this technology is grounded in real-world needs and challenges.' The project also aims to reduce the environmental and financial burden of widespread preventive spraying. Dr Akpokodje added: 'Addressing the challenge of early diagnosis of potato plant disease would boost productivity and reduce costs for farmers, while supporting more sustainable and targeted disease management. "By decreasing reliance on pesticides, this approach benefits both the environment and the long-term resilience of the potato industry. The technology also has the potential for wider application across other crops, driving innovation in agricultural practices.' Dr Aiswarya Girija from the Institute of Biological, Environmental and Rural Sciences at Aberystwyth University said: Potatoes are the fourth most important staple crop globally, and optimal production is essential for a growing global population. Potato blight is therefore not just a farming issue — it's a food security issue. 'As well as threatening the stability of food supplies, potato blight drives up production costs and reliance on environmentally harmful fungicides. The system we plan to develop will be capable of detecting early signs of disease before they become visible to the human eye, allowing for timely and targeted interventions.' The first stage of the DeepDetect project is a comprehensive feasibility study, including market research to understand the limitations of current early warning systems. The project team will then create an AI-powered prototype using image datasets of healthy and diseased potato leaves. Once the prototype has been developed, the team will conduct focus groups and workshops with farmers and agronomists to refine the model and ensure usability.

Cern decision by Cabinet opens up particle research opportunities for Ireland
Ireland's long journey to membership of Cern , one of the world's largest centres for scientific research, has reached its destination following a Cabinet decision. It opens up opportunities for Irish companies, scientists, students and wider society to reap the benefits of working in the world's most famous particle laboratory in Switzerland. The European Organisation for Nuclear Research (Cern) is home to the Large Hadron Collider, a huge underground ring in which protons – one of the constituent particles of an atom – are accelerated close to the speed of light and collided into one another. It was used to discover the Higgs boson, the so-called 'god particle', which gives matter mass and holds the physical fabric of the universe together. [ Q&A: It promises to boost research, industry and education. So, why has it taken so long for Ireland to join Cern? Opens in new window ] Many technologies developed at Cern have gone on to have applications in medicine, space, energy and ICT, such as the world wide web and touch-sensitive technology in smartphones. READ MORE 'Associate membership of Cern will demonstrate Ireland's commitment to science and reaffirm our reputation as a centre for scientific investment,' said Tánaiste Simon Harris after the Cabinet meeting on Tuesday. 'It will create opportunities for Irish researchers, students and industry to join world-class teams at Cern, and it will give Cern access to Ireland's talent and expertise.' 'Having personally advocated for Ireland's associate membership of Cern for a long time, it is a pleasure to officially announce [we] will join Cern in October this year. Today's Cabinet approval is a milestone which authorises the final legal steps,' said Minister for Science James Lawless . University College Dublin, whose physicists have been involved in Cern research for many years, said it is to expand its particle research capacity following Ireland's decision to become a member country. UCD vice-president for research, innovation and impact, Prof Kate Robson Brown said: 'This is a very important step for Ireland, to take our place in Europe's largest scientific organisation, which enables collaborations with the best researchers, institutions and companies all over the world.'
