Caving team discover 'dream' 10km network under Forest of Dean

BBC News4 days ago
An "exploratory urge" led to the discovery one of the largest cave systems found in Britain in a decade, with cavers saying it was "a dream come true".The network of passages and giant caverns stretching for 10km (6 miles) was found near English Bicknor in the Forest of Dean.The first part of the cave system, Redhouse Lane Swallet, was originally found in the 1990s by Paul Taylor, a caver from Gloucester.Conservation officer and retired physicist Dr Tim Nichols, who was part of a new generation of explorers which discovered the wider network of caverns, said he did not realise the significance of what they had recently found until they saw it.
"The first time when we stepped into the new passage when there was just two of us - all of our dreams had come true," Dr Nichols said."That exploratory urge to go and find where no person has ever been before is really special."With each trip it just kept getting better and better."He explained a strong draught in the boulder filled passage at the end of the original network of caves had inspired him to delve deeper.Through sheer determination his team of explorers successfully dug past the boulders in August last year."You have to pinch yourself, it is a once in a lifetime [find]."Every trip's just been like another birthday present and every trip we've been finding something different.""Caves remain one of those things on the planet that are largely undiscovered."True genuine exploration - that's what's exciting about it," Dr Nichols added.
Dr Nichols went on to explain how "it's the biggest find" in the UK in a long time.The last discovery was made in 2010 in what is now the UK's longest cave system called The Three Counties, which was initially thought to be three separate systems. But in 2010, cavers discovered they were in fact interconnected making it 87km (54 miles) long.
In the 1990s, Mr Taylor began exploration work on the Redhouse Lane Swallet in the Forest of Dean and after two years of digging discovered the initial cave system which was around a mile long.Mr Taylor said he is "extremely honoured and proud" to be a part of this history-making discovery."I started caving when I was just 13 years old and I'm 71 years old now," he said."To be the very first person to shine your light down that passage and put your footprints down - it's an amazing experience," Mr Taylor added.

Fossils of ancient shark species discovered in Kentucky cave

Fossils of an ancient shark species have been discovered in a Kentucky cave, officials announced during Shark Week. The Discovery Channel isn't the only one educating shark lovers this week. Mammoth Cave National Park recently announced the discovery of an ancient shark species with unique teeth. The ancient shark species, known as Macadens olsoni, 'is notable for its unique tooth whorl, a curved row of teeth designed for crushing small sea creatures,' Mammoth Cave said in a press release issued Thursday. The shark species likely grew to less than a foot long and probably ate mollusks and worms, according to the park. The fossils were found in the Ste. Genevieve Formation, which dates back to around 340 million years ago, when Mammoth Cave was submerged in a warm, shallow sea. 'This discovery is a remarkable addition to our understanding of ancient marine life and underscores the importance of preserving and studying our natural history,' Mammoth Cave Superintendent Barclay Trimble said. The shark species was named after Mammoth Cave and Rickard Olson, a retired park scientist, 'who played a crucial role in documenting shark fossils in the park as part of a recent Paleontological Resource Inventory', according to the park. 'This finding not only enhances our knowledge of ancient marine ecosystems but also emphasizes the critical role of paleontological research in our national parks,' Trimble said. He added: 'Every discovery connects the past with the present and offers invaluable educational opportunities for students and the public.' At least 70 species of ancient fish from more than 25 caves and cave passages have been identified at Mammoth Cave, including more than 40 species of sharks and relatives.

How have UK insects been affected by 2025's hot, sunny weather?

Certain insects - including ladybirds, butterflies and wasps - are thriving after the warmest and sunniest spring on record across the numbers, the main food source of ladybirds, boomed according to the Royal Horticultural Society after a warm start to the the relative lack of rain this spring and summer could lead to lower insect and amphibian numbers next year since eggs may not be laid and wetland areas are drying up. Insect numbers are difficult to quantify but research suggests that in the longer term, the UK's flying insect population is in decline. An abundance of aphids Whilst the long term picture for the decline of flying insects looks pretty bleak, there is no denying that this year has been a visibly bumper Brown is director of climate change and evidence at The Wildlife Trusts, a federation of 46 independent wildlife conservation charities in the UK. She said: "Many people across the UK are noticing more ladybirds, wasps and other insects this summer – off the back of a very poor year last year for species like butterflies."These are all species that thrive in warm, dry conditions. Earlier in the year the Royal Horticultural Society correctly predicted that we were in for an abundant year for aphids. Whilst that has proved a bit of a headache for gardeners, aphids form an important part of the food chain and are eaten by birds and other Hayley Jones, principal entomologist at the Royal Horticultural Society, says that their numbers are now beginning to drop off as their natural predator - the ladybird - is taking over and playing catch up. 'Extraordinary' year for early butterfly sightings Another much loved flying insect, the butterfly, is often seen as an important indicator of the general health of the immediate environment. These have been in general decline since the Richard Fox, head of science at the Butterfly Conservation charity, says that 2025 has been quite extraordinary in terms of early sightings with 18 species spotted at least two weeks earlier than average and a further 24 species seen at least a week is in contrast to last year's 'butterfly emergency', declared when the lowest numbers of butterflies were ever recorded. This followed a cloudy, wet spring and cool summer. Some varieties, such as the dark green fritillary did not have a single sighting in like all insects, are ectothermic (cold-blooded) and need the warmth and light of the sun to regulate their body temperature and give them energy to fly. This year's warmth has helped them move through their lifecycle quickly meaning their survival rate has been remarkably good; spending less time as caterpillars and as potential bird food. Lepidopterist Martin Wills, who records numbers at Hutchinson's Bank Nature Reserve in south London, confirmed that it has been a fantastic butterfly season so far with record numbers of early sightings. You can take part in 2025's Big Butterfly Count which is on until 10 August and go to BBC Weather to find out what the weather is doing in your area. Bumper year for lavender Not far from Hutchinson's Bank Nature Reserve in south London lie some of the UK's most beautiful lavender fields which are fantastic habitats for butterflies and especially bees. Lavender thrives in sunny, warm conditions with dry summers and mild winters. This year in the UK it has come into full bloom much earlier than usual, meaning more bees and butterflies earlier in the year. Lorna May, the owner of Mayfield Lavender in Surrey, told BBC Weather she had seen a tenfold increase on last year in honey production which she put down to the happy and soaring bee the number of pests have increased too including the tiny, shiny rosemary beetle which has exploded in number this year. To avoid using pesticides, an army of volunteers remove the beautiful bugs by cause for concern of an early lavender bloom for Lorna May is that the plant may die earlier and this could in turn have a notable effect on the local biodiversity for the rest of the summer. According to Kathryn Brown of The Wildlife Trusts, climate change is making things more chaotic for said: "We're waiting to see the statistics for this year, but it's likely that we are seeing greater 'boom and bust' cycles for wildlife as we experience increasing erratic weather patterns." The latest State of the UK Climate report published by the Met Office remarks that weather extremes are now becoming the new normal and that hotter, drier summers will become more of the 10 warmest UK springs have occurred since 2000, with the three warmest since course, wildlife are sensitive not only to weather extremes but also to the use of pesticides and loss of it is often overlooked how important insects are to our biodiversity, playing vital roles in almost every ecosystem. From pollination, to being an essential food source, to helping the decaying process. The Wildlife Trusts suggests you can help declining populations by mowing your lawn less often, supporting local rewilding projects and creating ponds.

Women's sport: Why we need to talk about periods, breasts and injuries

The Euros are reaching their conclusion in a massive summer across women's away from the drama and excitement on the pitch, there is also a scientific revolution taking place. Teams of scientists are researching the unique ways that elite sport affects the female body – how breasts alter the way you run, but the right sports bra could give you the edge; how the menstrual cycle could impact performance and what role period trackers could play; and why is there a higher risk of some injuries, and what can be done to avoid them?It's a far cry from the era when professional female athletes told me they were thought of simply as "mini-men". Breast biomechanics Cast your mind back to the iconic scene from the final of the last European Championships in was extra time at Wembley and Lioness Chloe Kelly scored the winning goal against Germany. In the ensuing euphoria, she whipped off her England shirt showing the world her sports was fitted by Prof Joanna Wakefield-Scurr, from the University of Portsmouth, who proudly goes by the nickname the Bra Professor. Here are her breast facts:Breasts can bounce an average of 11,000 times in a football matchAn average bounce is 8cm (3in) without appropriate supportThey move with up to 5G of force (five times the force of gravity), comparable to the experience of a Formula 1 driverLaboratory experiments – using motion sensors on the chest – have revealed how a shifting mass of breast tissue alters the movement of the rest of the body, and in turn, sporting performance."For some women, their breasts can be really quite heavy and if that weight moves, it can change the movement of your torso, it can even change the amount of force that you exert on the ground," Prof Wakefield-Scurr tells me. Compensating for bouncing breasts by restricting the movement of your upper body alters the positioning of the pelvis and shortens the length of each stride. That's why sports bras are not just for comfort or fashion, but a piece of performance gear."We actually saw that low breast support meant a reduction in stride length of four centimetres," Prof Wakefield-Scurr explains."If you lost four centimetres every step in a marathon, it adds up to a mile."Sports bras also protect the delicate structures inside the breast, "if we stretch them, that's permanent," the professor says, so "it's about prevention rather than cure". The menstrual cycle and its effect on performance The menstrual cycle has a clear impact on the body – it can affect emotions, mood and sleep as well as cause fatigue, headache and Calli Hauger-Thackery, a distance runner who has represented Team GB at the Olympics, says talking about its sporting impact is "still so taboo and it shouldn't be, because we're struggling with it".Calli says she always notices the difference in her body in the lead up to her period."I'm feeling really fatigued, heavy legs, I [feel like I'm] almost running through mud sometimes, everything's more strained than it should be," she finds she "lives" by her menstruation tracker, as being on her period is a source of anxiety "especially when I've got big races coming up".One of those big races was in April – the Boston Marathon – and Calli's period was due. She finished in sixth place, and recalls that she "luckily got through" - but says she can't help wondering if she could have done even better. Can elite sport damage women's fertility?Football boot issues reported by 82% of female players The menstrual cycle is orchestrated by the rhythmic fluctuations of two hormones – oestrogen and progesterone. But how big an impact can that have on athletic performance?"It's very individual and there's a lot of nuance here, it's not quite as simple as saying the menstrual cycle affects performance," says Prof Kirsty Elliott-Sale, who specialises in female endocrinology and exercise physiology at Manchester Metropolitan University."Competitions, personal bests, world records, everything has been set, won and lost on every day of the menstrual cycle," she famously includes Paula Radcliffe, who broke the marathon world record while running through period cramps in Chicago in 2002. Working out whether the menstrual cycle affects sporting ability requires an understanding of the physiological changes that hormones have throughout the body, the challenge of performing while experiencing symptoms, the psychological impact of the anxiety of competing during your period and perceptions about all of the Elliott-Sale says there "isn't a phase where you're stronger or weaker", or where "you're going to win or you're going to lose", but in theory the hormones oestrogen and progesterone could alter parts of the body such as bone, muscle or heart."What we don't yet understand is: Does that have a big enough effect to really impact performance?" she professor adds that it is "a very sensible conclusion" that poor sleep, fatigue and cramping would have a knock-on effect on performance, and that dread and anxiety were an "absolutely tangible thing" for athletes on their period who are performing in front of large has spoken to athletes who "sometimes even triple up with period pants" to avoid the risk of leaking and embarrassment, and "that's a heavy mental burden". Rugby union team, Sale Sharks Women have been working with Manchester Metropolitan University.I met Katy Daley-McLean, former England rugby captain and England all-time leading point team are having open discussions around periods to help them understand the impact that menstruation can have, and how to plan for it. This includes taking ibuprofen three days before, rather than thinking: "I can't do anything about it," Daley-McLean says."It's through that knowledge and that information that we can talk about this, we can put plans in place, and we can change our behaviour to make you a better rugby player," she says. How to avoid injuries One issue that has emerged as women's sport has been given more attention is a difference in the susceptibility to some of the attention has been around the anterior cruciate ligament (ACL) – a part of the knee that attaches the upper and lower parts of the leg together. Injuries can be brutal and take a year to recover only is the risk three to eight times greater in women than men, depending on the sport, but they are becoming more common, says Dr Thomas Dos'Santos, a sports biomechanics researcher at Manchester Metropolitan University. However, there is "no simple answer" to explain the greater risk in women, he it could be down to differences in anatomy. Bigger hips in women mean the top of the thigh bone starts from a wider position and this changes the angle it connects to the lower leg at the knee, potentially increasing risk. The ACL is also slightly smaller in women "so it's a little bit weaker, potentially", Dr Dos'Santos explains. ACL injuries can happen at all stages of the menstrual cycle, but hormonal changes are also being investigated, including a study sponsored by Fifa, the governing body for world football. High levels of oestrogen prior to ovulation could alter the properties of ligaments, making them a bit more stretchy so "there could be an increased risk of injury, theoretically," he Dr Dos'Santos argues it's important to think beyond pure anatomy as women still do not get the same quality of support and strength training as compares it to ballet, where dancers do receive good quality training. "The [difference in] incidence rates is basically trivial between men and women," Dr Dos'Santos is research into whether it is possible to minimise the risk of ACL injuries, by training female athletes to move in subtly different there is a risk of lessening performance, and some techniques that put strain on the ACL – like dropping the shoulder to deceive a defender before bursting off in another direction – are the necessary moves in sports like football."We can't wrap them up in cotton wool and say you should avoid playing sport," Dr Dos'Santos says. "What we need to do is make sure that they're strong enough to tolerate those loads, but it isn't just as simple as some people saying we can 100% eradicate ACL injuries, we can't." No longer 'mini-men' Even though there are still many unanswered question, it is still a world of difference for Katy Daley-McLean at Sale Sharks she got her first cap in 2007, she remembers that all the assumptions around how her body would perform were based on the data from male rugby players."We were literally treated as mini-men," Daley-McLean now, she says, girls and women don't feel like the outsiders in sport, which is not only improving performance at the elite level but helping to keep more women in sport."It's awesome, it's something to be celebrated because if you look at the stats, one of the biggest reasons young girls drop out of sport is body image, it's around periods and not having a correct sports bra, which is so easily sorted."Inside Health was produced by Gerry Holt
