There's nothing better than a hot bath to warm up and unwind on a chilly winter evening - but water bills don’t come cheap, so it’s more important than ever to make sure you’re making the most of your time in the tub. So how long should we be spending in the bath? Well, a recent study has uncovered that 22 minutes is the optimum length of time to spend in the bath. The study conducted by Victorian Plumbing sought to discover ULTIMATE bath time for relaxation, hydration and a good night’s sleep. There were 20 participants involved in the experiment - half male and half female - who took baths of varying lengths and rated how they felt afterward based on a number of factors. The study concluded that 22 minutes is the optimum amount of time to spend in the tub - to feel relaxed, hydrated, and sleep well after. Soaking should stop at 27 minutes if you don’t want to stay feeling hydrated post-bath, according to the study. This supports the advice of some professionals, who suggest that baths should be no longer than 30 minutes. It was also uncovered that baths impact men and women slightly differently. Women have a better night’s sleep after a longer bath, ideally, 30 minutes long, whereas men sleep better after 19 minutes. Those who felt more relaxed after the baths had scrolled on their phone during their time in the tub, whereas those who watched TV were found to be the least. Sorry to burst your bubble bath lovers, but the findings also suggest that people who take more baths are generally more stressed - although they find them more relaxing than shower- on the whole. “When the nights start getting colder in the UK, we tend to see an increase in Brits looking to buy a bath. And who can blame them? There are a number of benefits of a bath; they’re soothing, and cleansing and studies have even suggested that there are similar benefits to exercise," Brenna Ryan from Victorian Plumbing said about the study's findings. “To help you get the most out of your bath, we conducted a study which found that the optimum time to spend in the tub is 22 minutes - to leave you feeling relaxed, hydrated and sleep like a baby.” How to join the indy100's free WhatsApp channel Sign up to our free Indy100 weekly newsletter Have your say in our news democracy.

The name “core” suggests something hard and fixed but, it turns out, the Earth’s core is leaking. That is, at least, according to a team of top scientists, who drew the conclusion after analysing 62-million-old Arctic rocks. Geochemists from the California Institute of Technology and Woods Hole Oceanographic Institution detected record concentrations of helium 3 (3He) and helium 4 (4He) isotopes in the rocks, which suggest a slow trickle up from the very heart of our planet. They believe there could be reserves of the elusive gas buried some 2,900km underground. Helium is a surprisingly rare element on the Earth’s surface and experts have yet to establish just how much of it remains trapped deep beneath our feet. However, the new discovery has provided them with a fresh insight into the most mysterious region of our world. Understanding the presence of these helium isotopes could illuminate key processes in the core, such as how the Earth generated its life-protecting magnetic field. Most helium in the universe dates back to the Big Bang which occurred 13.8 billion years ago. The Earth swallowed up some of this as an infant planet, but mostly burped it all away during its 4.6 billion-year-long formation, as Science Alert reports. This means that any traces of helium found in volcanic rock – such as the samples unearthed in the Arctic – are believed to come either from pockets of mantle that are yet to release their helium, or from a vast, slow-leaking reserve. Basaltic lavas on Canada's Baffin Island contain some of the world's highest ratios of 3He to 4He, which geologists believe indicates that the gas's presence is not to do with the atmosphere, but rather the sign of deeper terrestrial origins. Several years ago, geochemist Forrest Horton uncovered helium isotope ratios of up to 50 times that of atmospheric levels in samples collected from Baffin's lava fields. This unusual concentration was also detected in lavas collected from Iceland. Horton and his team wondered if the helium in both samples may have derived from an ancient reservoir deep within the crust. And, it seems, their hunch may have been right. Their latest analysis – including specimens of the mineral olivine taken from dozens of sites across Baffin and surrounding islands – has delivered the highest ratio of 3He to 4He ever recorded in volcanic rock – measuring nearly 70 times anything previously detected in the atmosphere, as Science Alert notes. The team also considered ratios of other isotopes in order to rule out factors that may have altered the helium’s composition post-volcanic eruption, and found that the ratio of isotopes in the gas neon also matched the conditions present during the Earth’s formation. Despite advances in geology, the Earth’s core remains a great mystery, given that we have no way of directly exploring its core. The deepest hole humans have ever dug – branded the "entrance to hell" – extended an impressive 12,263m (40,230ft) down, but even that doesn’t come close to breaking through the crust to the layers beneath. Still, thanks to techniques like seismic tomography – which analyses how waves of energy travel through different materials during earthquakes – we’ve been able to map out the world’s interior. And carefully crafted simulations, based on the thermodynamics and pressures of our planet’s innards, suggest reserves of noble gases (like helium and neon) trapped in the core could have been protected as the Earth grew before seeping into the surrounding mantle over time. If the core is leaking, this could teach us a thing or two about how planets like ours form and how life, eventually, emerges.

When A-Level results day comes around, the annual Jeremy Clarkson tweet is tradition - and this year's tweet has been backed by Rishi Sunak. Since 2014, the former Top Gear presenter has taken to Twitter/X to share the fact that he got a C and 2 U's when he was at school and that despite his results, he ended up doing well for himself. At the end of each tweet, there is a new and not-so-humble brag about his success - such as having "loads of friends and a Bentley [in 2021]," and "a Mercedes Benz [in 2014]." So what was Clarkson's 2023 results day tweet? "It’s not the end of the world if your A level results aren’t what you’d hoped for. I got a C and 2 Us and here I am today with my own brewery," the 63-year-old tweeted. Now, prime minister Rishi Sunak has supported Clarkson's message with a retweet and noted how he has a "good point." "Jeremy has made a career of being the exception not the rule but he does have a good point here: Results day is important, but not necessarily a deal-breaker," Sunak tweeted. He added: "Whatever results you got today, there are lots of options available to you." Though some were far from impressed by the endorsement given the presenter's controversies over the years and the fact that both Sunak and Clarkson went to private schools.

Nasa scientists have found a planet they believe is covered by active volcanoes. In a study published in the journal Nature, scientists said they found the planet, which is the size of Earth about 90 light-years from Earth in the Crater constellation. They called it LP 791-18 d and one part is constantly scorched by sunlight, while the other is always in darkness. “The day side would probably be too hot for liquid water to exist on the surface. But the amount of volcanic activity we suspect occurs all over the planet could sustain an atmosphere, which may allow water to condense on the night side,” Björn Benneke, one of the astronomers who studied the planet, told NASA’s Jet Propulsion Laboratory. Sign up to our free Indy100 weekly newsletter The LP 791-18 system contains at least two other planets, called LP 791-18 b and c. The latter is two-and-a-half times larger than Earth and more than seven times its mass. It also affects the orbit of LP 791-18 d, making it travel along an elliptical path around the system’s sun. That path means LP 791-18 d is deformed every time it completes an orbit. “These deformations can create enough internal friction to substantially heat the planet’s interior and produce volcanic activity at its surface,” according to NASA. “A big question in astrobiology, the field that broadly studies the origins of life on Earth and beyond, is if tectonic or volcanic activity is necessary for life,” study co-author Jessie Christiansen said. “In addition to potentially providing an atmosphere, these processes could churn up materials that would otherwise sink down and get trapped in the crust, including those we think are important for life, like carbon.” Have your say in our news democracy.
