Skye footprints clue to dinosaurs' drinking habits
Huge meat-eating dinosaurs and their plant-eating prey shared the same watering holes on Skye 167 million years ago, say scientists.University of Edinburgh researchers examined dozens of dinosaur footprints at Prince Charles's Point on the island's Trotternish Peninsula.The dinosaurs included carnivorous megalosaurs - ancestors of Tyrannosaurus rex - and long necked herbivores that were up to three times bigger in size than an elephant.The scientists analysed the footprints to understand how the animals had moved, and suggested the different dinosaurs had "milled around" shallow freshwater lagoons.
The researchers said the behaviour from the Middle Jurassic was similar to how animals congregated around watering holes today.
More than 130 footprints have been found so far at Prince Charles's Point, on Skye's north coast.The area is named after Bonnie Prince Charlie who had sought shelter on the peninsula while fleeing British government troops after the Battle of Culloden in 1746.The scientists said the footprints suggested meat-eating theropods and plant-eating sauropods habitually spent time in lagoons.They said subsequent discoveries had made the area one of the most extensive dinosaur track sites in Scotland.
The Edinburgh research team's Tone Blakesley said the footprints provided a "fascinating insight" into dinosaur behaviour.Palaeontologist Steve Brusatte added: "Prince Charles's Point is a place where Scottish history and prehistory blend together. "It's astounding to think that when Bonnie Prince Charlie was running for his life, he might have been sprinting in the footsteps of dinosaurs."The first three footprints at Prince Charles's Point were discovered five years ago by a University of Edinburgh student and colleagues.
Important fossil discoveries have been made on Skye over the last 40 years.They include a pony-sized dinosaur that lived 166 million years ago, and adult and juvenile mammals of the shrew-like Krusatodon.The island also saw the discovery of the largest Jurassic pterosaur fossil, Dearc sgiathanach - a 170-million-year-old winged reptile.

How Britain can poach America's top scientists
From the time of Newton, Britain led the world in science. That began to change in 1940, when, with the Battle of Britain raging, Winston Churchill sent the scientist Henry Tizard on a secret mission to America. His objective was to secure financial and industrial help in the fight against Hitler. His currency was British military technology, in particular the cavity magnetron, a device that made it possible to locate the enemy with radar. This wowed the Americans and achieved his objective. According to one historian, it was 'the most valuable cargo ever brought to [America's] shores.' While this was a hand-over of scientific power, it catalysed the Anglo-American scientific alliance, which has seen a flow of talent ever since between our two nations. At times there have been concerns that this might be one-way traffic: from us to them.

Inside the Edinburgh firm on a mission to end fuel poverty
Urban Tide is a data company focused on unlocking information to deliver targeted solutions to businesses looking to improve sustainability outcomes. The founders met while delivering an ambitious 'Future Cities' programme that made them realise combining datasets was the future of targeted decision-making, but that many barriers stood in the way. Now the 15-strong company is a key partner in a five-year research project looking to link health data with household data to improve children's health. Specifically, it's looking at preventing the respiratory problems caused by damp and mould in poorly insulated or poorly ventilated homes. It's led by Dr Olivia Swann who is both a paediatrician and a researcher at the University of Edinburgh. 'The work that Livvy [Dr Swann] is doing is pretty fascinating,' Tricker said. 'The UK has the leakiest homes in Europe. It's a combination of having a lot of old stock, the way we build them is not that efficient and we're not really considering the thermal efficiency of buildings. 'The retrofit programme at scale needs to really be ramped up because if we reduce energy, we reduce our bills and make our homes more comfortable. But – and here comes the but –there's a risk if you clad a home and make it nice and insulated, it's not well ventilated. If you don't consider the ventilation systems, you can increase the risk of mould build-up, which can then lead to the risk of black mould, which, if you've children in the house, can lead to an increase in asthma and a whole host of health implications for later life.' Thanks to Urban Tide's unique access to system data from electricity smart meters, it can provide the research team with information that uses AI and household-level information to predict the risk of fuel poverty. Added to this is the Scotland-wide health data, held securely and strictly anonymised, which Swann's team can overlay with the data provided by Tricker's team, as well as other advanced data sets. This research, inspired by the children coming into Dr Swann's clinic with respiratory infections, is only possible now that all the pieces of the data jigsaw are available. Currently, it would not be possible even over the border in England, and interest from partners has exceeded all Swann's expectations. 'I've been really overwhelmed not just with the amount of interest but also just how incredibly collaborative and how much goodwill there is from industry, from policymakers and from third sector,' Swann said. 'We arranged a project launch event and I thought it would be 20 people and some sandwiches. Instead, we had 130 people and 50 different organisations. Most of those people I had met on Zoom or Teams, and then they had come in person because they felt so strongly about this issue. I think that is a real testament to how important people think this issue is and the will for it to be better.' It's the Goldilocks analogy of 'just right' as it applies to the population of Scotland and the quality of the data, alongside the expertise of companies and researchers and the involvement of Scottish government in potentially turning this research into policy that inspires Tricker. 'We're always looking at how we can use data to help solve a number of these large societal challenges,' he said. "So we wanted to build a platform that could bring in real-time data,' he said. 'We work across the transport sector as well, because they collect lots of real-time information. By combining that with other static data sets, you can start to see patterns. 'In the transport sector, for example, we're working with Cycling Scotland and other partners across local authorities and regional transport partners to try and help put in infrastructure where it's needed.' With this research project involving so many datasets from different partners, including, for the first time, Scottish government data on every intervention made so far to make houses warmer, the ethics of data use have been a priority. 'This data could not be harder to bring together,' Swann said. 'All of the data goes into the National Safe Haven, which is incredibly well protected. The data is then linked there, and it's anonymised before we begin to access it. So we never know who anybody is. 'We have a fantastic patient and public engagement group too and a lot of the discussions we've had with them have been about the acceptability of using these different kinds of data, bringing them together and all of the security measures around them.' Tricker adds that the anonymity of the data Urban Tide is using is absolutely key. It is not interested in personal details but looking for patterns in usage so the right interventions can be made. It will shortly be launching which will open up the data it has collected on transport across Scotland, including cycling networks, so it can be used to make local and national decisions. 'I'm quite excited about launching to really showcase some of our AI technologies and obviously help to promote more open data generally as well,' he said. Urban Tide is already working internationally from its Edinburgh base. It is leading an open data training programme for Ireland's public sector to comply with a European directive to make public data more accessible, and the team is also working on smart city plans in the middle-east and Australia. After 11 years of organic growth, bootstrapping and pivoting as the technology and AI capabilities develop, it is now looking to raise some investment. Assisting with this is Mountside Ventures, which it sees as a 'badge of honour' as it selects a only handful of companies to work with each year. 'The next three years are about really consolidating the business and the technology that we've built across UK and Europe and the next round after that would be to expand into America. We're on the journey of the 'three I's, so there's the identification piece, then there's the intervention and then how do you measure impact? We are also cross-sector. It's one of the challenges of our business, having to work in the energy sector, the transport sector, and then combining data from across the different sources. 'But that's also the opportunity because as more data are being opened up and used, the convergence of all these different types of data really unlocks new opportunities.'

'Strawberry Moon' to rise in rare sky event not repeating until 2043
The first full Moon of meteorological summer, known as the 'Strawberry Moon', will light up the skies for stargazers on June 11 - the Moon will sit low in the southern sky Stargazers in the UK are gearing up for a cosmic display as the 'Strawberry Moon' is set to rise next week, but something's different this time around. June's full Moon is an event that casts a glow on our celestial neighbour when sunlight completely illuminates the side of the Moon facing Earth – an occurrence that takes place every 29.5 days, marking a full lunar cycle. The approach of summer heralds the first full Moon of the season, affectionately termed the 'Strawberry Moon', scheduled to grace the night sky on June 11. However, due to a recent occurrence known as a "major lunar standstill", this year's Strawberry Moon will find itself in an atypical position in the British skies. Observers can expect to see the full Strawberry Moon hanging unusually low in the southern sky - the lowest it gets throughout its 18.6-year orbital journey. It's been a long time since the full Moon appeared so low, with the previous occurrence dating back over 18 years to 2006, and it won't repeat until 2043. But what exactly makes the Strawberry Moon standout, and does it actually look different? The Moon dances around Earth in a tilted orbit, which spans almost 20 years, leading to interesting phenomena such as major and minor lunar standstills, during which the Moon reaches extreme points on the horizon, making it appear peculiarly low or high in the sky. Stargazers are in for a treat as the Strawberry Moon is set to rise just 10 days before the summer solstice on June 21, promising a celestial spectacle, reports the Manchester Evening News. NASA has revealed that moons generally appear lower in the sky around the summer solstice, explaining: "On the summer solstice the sun appears highest in the sky for the year. Full moons are opposite the sun, so a full moon near the summer solstice will be low in the sky." Not only will the Moon be hanging low in the night sky, but it's also expected to look larger than usual, with BBC Sky at Night Magazine confirming this illusion. The reason behind the Moon's enlarged appearance is its proximity to the horizon, which tends to make it seem more substantial than it actually is. Best time to see 'Strawberry Moon' in UK For those keen to catch a glimpse of the 'Strawberry Moon' in the UK, mark your calendars for 8.44am BST when the Moon will reach its full phase. Although it will be daylight by then, with sunrise at approximately 4.45am on June 11, the prime viewing time will be at dusk on Tuesday, June 10, when the Moon will dominate the night sky, appearing full all through the night. Why it's called the 'Strawberry Moon'? Each month's full Moon has its own unique moniker; January's is known as the 'Wolf Moon', while February's is dubbed the ' Snow Moon'. Despite not taking on a berry-like hue, the 'Strawberry Moon' owes its name to the season when wild strawberries begin to ripen, as noted by the Farmers' Almanac. Other traditional names for this June spectacle include Rose Moon, Hot Moon, and Mead Moon. Below is the full Moon schedule for 2025, as well as the name given to each one: Monday, January 13 – Wolf Moon Wednesday, February 12 – Snow Moon Friday, March 14 – Worm Moon Saturday, April 12 – Pink Moon (Micromoon) Monday, May 12 – Flower Moon (Micromoon) Wednesday, June 11 – Strawberry Moon Thursday, July 10 – Buck Moon Saturday, August 9 – Sturgeon Moon Monday, October 6 – Hunter's Moon (Supermoon) Wednesday, November 5 – Beaver Moon (Supermoon) Thursday, December 4 – Cold Moon (Supermoon)
