Severn Bore's history: Dog cruelty and surfing firsts
People will gather on the banks of a river later to watch a world-famous natural phenomena roar through Gloucestershire. The Severn Bore occurs when a large tidal surge pushes up the River Severn against a current, causing towering waves. It's an event surfers don't want to miss, but in the past some unusual things happened including dog cruelty and surfing firsts.Monday will see a "four star" bore weave its way down the river. The banks will be lined with wellie-wearing spectators, with surfers taking advantage in the water.Records from the past few hundred years show how people have viewed the natural event.A description of the bore from the 1700s, attributed to Sir Charles Blagden, a physician and secretary of the Royal Society in 1748, described how Gloucester residents would gather at "the Parting of the Water" at Alney Island.The parting is a reference to how the river flows around the island before reuniting again near Maisemore."If the wind gets up the river, one can sometimes, even at this interval of time, hear a very distant roaring by putting the ear close to the water," he wrote.
But once the bore got closer, "about 200 yards off", Sir Blagden said, the way some onlookers celebrated its arrival was slightly disturbing.He wrote: "There are commonly some men in boats to meet the tide, and some dogs are thrown in just as it comes, to observe their howling and distress.
"On a sudden, the boats and dogs are instantaneously raised up and thrown into violent agitation, and at the same time, a vast wave or wall of water... is seen approaching with extreme rapidity."Sir Blagden added several ships had been lost to the bore, so watermen trading on the Severn were "extremely careful not to be taken disadvantageously by the head of the tide".Elsewhere, he wrote that the bore rose to eight ft (2.4 metres) in height, and that he raced it on horseback between bends in the river in a bid to "overtake" the surge.In the 20th Century, Arnold Whitehouse, senior science master at The Crypt School, studied the relationship shared between the tidal Severn and the moon.
'Unusually big tide'
Ahead of the bore on 17 November 1910, Mr Whitehouse wrote: "Such an unusually big tide so far from the equinoxes is due to the moon happening to be full on the same day it is at its nearest to the earth."He claimed the bore that day was 30ft or 9.2m, the same height as the largest recorded bore would go on to be more than 50 years later in 1966.In 1955, Colonel John Churchill, known as "Mad Jack", became the first person to surf the bore, standing atop a homemade board.According to the Museum of British Surfing, this is thought of as being the first incidence of someone riding a tidal wave in a river.
The four star bore on Monday, which classed as a "large" bore, after being downgraded from a "very large" five star bore, will reach Minsterworth at 10:11 BST, Stonebench at 10:26 BST, and Over Bridge at 10:46 BST.As the bore can arrive up to 20 minutes early or 30 minutes late, depending on weather conditions, those planning on watching are often advised to arrive early and find a good vantage point.A three star bore will follow in the evening, reaching Minsterworth at 22:31 BST, Stonebench at 22:46 BST, and Over Bridge at 23:06 BST.

Aliens, asteroid mining … and Mars births? Royal Society envisions next 50 years in space
Humanity must prepare for a sweeping revolution as nations and companies gear up to build moon bases, space stations and orbiting factories, and uncover evidence – if evidence is out there – that we are not alone in the universe. A horizon-scanning report from the Royal Society envisions a new era of space activities that will reshape the world, including clean energy beamed to Earth, robots that mine asteroids or recycle dead satellites, and manufacturing plants that circle the planet churning out products labelled 'Made in Space'. Prediction is difficult, especially about the future, but the report anticipates radical developments that will generate some of the most important technological and economic opportunities of the century. While some countries are well-placed to benefit, Britain lacks a clear plan and is at risk of missing out, the authors warn. 'We're not trying to predict the future, but these are the sorts of things that could happen,' said Sir Martin Sweeting, the report's co-chair and professor of space engineering at the University of Surrey. 'And if we think about them sooner rather than later, we'll be better off.' The Space: 2075 report aims to kickstart discussions on the possibilities and consequences of space science and technology over the next 50 years, so governments, regulators, businesses and the public can prepare. The implications are as consequential to today's industry, society and culture as the Industrial Revolution was in the 18th century, the authors write. Future advances in reusable rockets and spaceplanes may pave the way for factories that make products feasible only in microgravity and larger-scale facilities for constructing spacecraft that could never launch from Earth, the report says. Interplanetary space stations could be built in orbit and deployed across the solar system as desired. Existing industries may relocate into orbit. Power-hungry data-farms, for example, would benefit from plentiful solar energy and free cooling in space. Meanwhile, radical new technologies may emerge, such as satellites that capture solar energy and beam it efficiently through the atmosphere to ground-based receiving stations by converting it into microwaves or laser beams. The ever-increasing volume of space debris from spent rockets, defunct satellites and fragments from collisions and explosions is driving ambitions to recycle the junk. This would reduce collision risks and prevent the materials from polluting the atmosphere when they burn up on re-entry. As space becomes more congested, conflict becomes more likely, the authors warn, with nations and companies clashing over prime spots on planetary bodies, valuable orbits and critical radiofrequency bands. While the UK is strong on a handful of technologies such as Earth observation, communications and small satellites, it needs a 'clear national ambition' to keep up with the pace of change, the report finds. 'The UK government, the international community, and society at large need to comprehend, anticipate and be prepared,' it states. Ethical challenges are expected, too. Extremophile bugs that endure harsh environments on Earth could be engineered to make 'living tools' on Mars that convert natural resources into useful compounds. But what if those bugs colonise the planet and crowd out yet-to-be-discovered native microbes? Terraforming trials, in which patches of planets are engineered to be more hospitable to humans, raise similar concerns. And if humans move to the red planet? 'What happens if we end up with humans being born on Mars?' asks Sweeting. At several public workshops convened for the report, questions arose about alien life and how it should be handled should proof arise. One participant at a workshop in Wrexham marvelled at the number of galaxies in the cosmos. 'In all those galaxies, there has to be one planet to have something similar to a caterpillar,' they asserted. If aliens, caterpillar-like or otherwise, live nearby, we will probably know in the next 50 years, the authors write. 'I would hope that would bring nations together and say: let's forget about our petty arguments and think about the bigger issues,' said Sweeting, 'but that may be wishful thinking.'

How to tell if a seagull is going to steal your food
A seagull eyeing your lunch or ice cream is unlikely to try to steal it if not part of a flock, scientists have found. Due to an instinct known as neophobia, which means a fear of the unknown, scientists have discovered that herring gulls are mostly reluctant to attack when on their own. But, according to researchers at Ghent University, this fear diminishes when seagulls are part of a flock – potentially putting your food at greater risk. In a study published in the Royal Society Open Science journal, scientists carried out experiments involving a group of 54 seagulls they had reared from hatching. In order to gauge how quickly the gulls would take to approach their food if faced with an unfamiliar object nearby, the scientists placed a range of items – a multicoloured ball, a bucket, brush, folder and jerrycan – next to the gulls' food supply. Some of these objects were familiar to the birds and others were new to them. They found that, when alone, the gulls took an average of 9.81 seconds to approach their food bowl when faced with an unfamiliar object – compared with just 3.52 seconds when in a group. Notably, 24 of the gulls did not eat at all when alone and faced with an unfamiliar object. The scientists also found that the birds were willing to spend more time near their food when in a group than those on their own. Lone gulls spent an average of just 38.8 seconds near their food, compared with 111.8 seconds when in a group – while 16 birds did not approach their food at all. The study states: 'Individuals tested in groups were quicker to eat and spent more time near a novel object than individuals tested alone. 'The results of our study suggest that the presence of group members reduces perceived individual risk, allowing individuals to behave less cautiously.' Noting that 'each bird likely perceives the risk to be shared by the group', the authors said their findings were consistent with previous studies showing that social animals often rely on the presence of the group to make quicker decisions and engage in potentially risky situations. An accompanying release from the Royal Society added: 'When confronted by a gull after your chips it might be best to catch them one-on-one.' While there may be some comfort in the findings that a lone seagull could pose less of a threat of theft, a previous study has suggested that gulls actually prefer food that they have seen being handled by humans, as opposed to food left lying unattended. Although in a further possible line of defence, an earlier study suggested that staring at a seagull could help to deter it from trying to take your food. Scientists at the University of Exeter found that gulls took an average of 21 seconds longer to approach a bag of chips if they could see they were being watched, with just 27 out of 74 birds observed being too cautious to take a chip when a human was nearby.
