Pacer Brydon Carse will replace injured Reece Topley in England's World Cup squad, the ICC announced on Monday.

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.

A new sense of urgency is pushing Manila and Beijing to greater assertiveness in the South China Sea.

Naomi Osaka has reflected on battling self-doubt and difficult thoughts as a new mother. The four-time Grand Slam tennis champion gave birth to her first child, a daughter named Shai, in July 2023. She shares Shai with her partner, rapper Cordae. On Sunday (22 October), Osaka shared some insights into her personal life with her fans to mark turning 26 earlier in the week. In an extended post on X, formerly Twitter, the Japanese athlete wrote about taking stock of her life so far, and wondering whether or not she’s taken the “correct path”. “I often try to retrace my steps to figure out how did I end up here,” she explained. “I know I say this often but I truly still feel like that kid playing on public courts in Queens, NY. “Randomly I wonder if I’m doing OK, is there a correct path to take in life or have I veered off onto the scenic route for a little bit? However, I’ve now come into the mindset that I can only keep moving forward and everything that will be, will be.” Osaka then shared her specific feelings of worry about her capabilities as a parent. “Something I had to conquer recently is fighting the thought that I won’t be a good mom,” she wrote. “So many doubts raced through my head I had to swat them away like mosquitoes. “Looking into Shai’s eyes and holding her I always think, ‘Wow this little person depends on me so much, I have to do better.’ It’s such a strange feeling watching your kid grow, you blink and they’re double the size in a few months. “Gratefulness reminds me to breathe and take in the little things (and the big ones).” Osaka ended her post by expressing her gratitude for having “another year” and for the people who support her. Osaka’s last competitive match was at the Toray Pan Pacific Open in September 2022, before she withdrew from the tournament due to abdominal pain. She announced her pregnancy in January 2023 shortly after stating that she wouldn’t be competing in the Australian Open later that month. Last month, Osaka spoke about her year away from playing tennis and mentioned how other female tennis stars’ longevity has influenced her desire to keep competing. “The whole process, it felt long and short at the same time,” she told the American sports news channel ESPN. “When I stepped away, it was Tokyo, that was the last tournament I played. I just remember watching the Australian Open and being very devastated, because I’ve never missed an Australian Open. “When I was watching Serena and Venus [Williams], I was thinking, ‘Ah, I probably no way will ever play at their age’, but sitting here, I’m like, ‘You know what? I might do that actually.’” Read More ‘Truly heartbroken’ Rebecca Adlington reveals late miscarriage Should we stop putting the clocks back?

Rebecca Adlington has said she’s “truly heartbroken” as the British swimmer announced she had a miscarriage at 20 weeks pregnant. Adlington, 34, said she went for her 20-week scan earlier this week and was informed her baby had no heartbeat, adding she and husband Andy Parsons, 31, “will forever love and remember” their daughter. She wrote on Instagram: “I don’t really have the words right now but unfortunately we went for our 20-week scan this week and they discovered no heart beat [sic].” Adlington added that she gave birth to the baby – who the couple named Harper – on Friday (20 October) and “we held her, and had time with her”. The two-time Olympic gold medallist thanked the staff at the Wythenshaw hospital in Manchester for their “incredible” kindness and care, and Parsons for his “selfless support, love, and help”. “I don’t have the strength or words right now and don’t feel ready to share this news,” Adlington continued. “However, I can’t pretend to be okay or fake a smile. I can’t have people ask me how pregnancy is or when I am due as I still look pregnant. I don’t have the strength to tell this news individually.” The former I’m a Celebrity contestant announced she was pregnant on 1 October, sharing a photograph of her family taken at Disneyland Paris. Former track athletes Dame Jessica Ennis-Hill and Greg Rutherford, ex-hockey player Sam Quek, former swim champion Adam Peaty, and presenters Angellica Bell and Helen Skelton shared messages of support in the comments section of Adlington’s Instagram post. Ennis-Hill wrote: “Oh Becky I’m sending you and your family so much love. I’m so sorry xxxx.” Rutherford said: “Sending love to you. So sorry to read this Becky xx.” Quek also wrote: “Becky, I know no words will ease the pain… my entire heart is with you all.” Peaty’s message read: “I’m so sorry to hear this, my prayers are with you all” alongside a heart and praying hand emoji. Adlington previously revealed she had a miscarriage 12 weeks into her pregnancy last August, sharing the news on Instagram at the time. The mother-of-two wrote: “It’s such a devastating time but important in times like these we remember we aren’t alone and have so much support. “Long way to go but I’m in the right place,” she added. “Once I’m able to leave hospital I’m extremely grateful I get to go home and give my 2 little ones the best hugs!” Adlington, who has also appeared on Celebrity MasterChef, shares one son, Albie, two, with Parsons. She also has an eight-year-old daughter, Summer, from her first marriage to swimmer and personal trainer Harry Needs.
