In today's newsletter: Is it really that cold for this time of year or have we just got used to recent warmer summers? Meteorologists say it's a bit of both Sign up here for our daily newsletter, First EditionGood morning. First of all an apology, yesterday's newsletter was sent out in error - we apologise for the mistake, and below is today's First Edition.Isn't it an unseasonably chilly one? Yesterday I found myself fishing out a winter wooly hat for the morning dog walk here in London. But is it really that cold for mid-June or do we all just think it's cold because we've got used to recent warmer summers caused by the climate crisis and global heating?General election | The Green Party launches its manifesto today with proposals to spend 49bn insulating homes and public buildings and to let councils requisition empty properties.Child exploitation | Hundreds of unaccompanied child migrants across Europe are being forced to work as soldiers for increasingly powerful drug cartels to meet the continent's soaring appetite for cocaine, a Guardian investigation has found, with police warning of industrial-scale exploitation of African children in western European cities including Paris and Brussels.Israel-Gaza | The US secretary of state, Antony Blinken, said endorsement of the UN security council's ceasefire resolution by Hamas officials was a hopeful sign", but the group's leadership in Gaza needed to sign off on the deal.Heath | Tobacco, alcohol, processed foods and fossil fuels kill 2.7 million people a year in Europe, according to the World Health Organization, which has called on governments to impose tougher regulation of health-harming products.France | Eric Ciotti, the leader of France's mainstream rightwing Les Republicains party, has said he would back an alliance with Marine Le Pen's far right National Rally in the snap legislative elections later this month, shocking opponents and party members and throwing French politics into further disarray.

More than 110,000 children in England and Scotland are still suffering. For Toby, it has meant pain, crushing fatigue and sadness - as well as months off schoolIt is a few days after Arsenal have beaten Spurs and I'm discussing the game with 12-year-old Toby. A huge Tottenham Hotspur supporter, Toby is also magnanimous in defeat. He admits that, despite a major second-half wobble, Arsenal (my team) are playing better football at the moment. Davies couldn't handle Saka, Son has gone off the boil, only Romero came out with any credit.I'm enjoying talking football with Toby. He is clearly incredibly knowledgable as well as passionate about it. It's zero surprise to learn he has three fantasy football teams on the go. Continue reading...

Biochemist found cholesterol-lowering compound in 1973 and the drugs have prolonged millions of livesThe scientist whose work led to the creation of statins, a chemical that prevents heart attacks and strokes, has died aged 90.Akira Endo found the first cholesterol-lowering compound in 1973 in a lab in Tokyo.

We're 50 years apart and have never met, but my connection with Pauline is deeper than I could have imaginedAll best friends were strangers once. Why, then, does reaching out to someone you don't know, making platonic connections in the modern world, feel like such a bold, even brave thing to do?Let me tell you about my friend, Pauline. Like all good friends, we make a point of catching up at least once a week, talking for hours about everything and nothing at all. But Pauline and I, while always there for each other, are unlike more conventional companions because, as well as being born 50-odd years apart, and living several hundred miles from each other, we've never actually met. We're telephone friends. Continue reading...

American astronaut who took the celebrated 1968 Earthrise photograph during the Apollo 8 mission to orbit the moonIt may be that the most famous picture from the US space programme is not the shot of Neil Armstrong landing on the moon, but the image of Earth, seen rising above the moon's horizon, an image relayed from space on 24 December 1968 by the crew of Apollo 8 - Frank Borman, Jim Lovell and Bill Anders.It was Anders, who has died aged 90, who snapped the Earthrise" photograph, which was not part of the mission's scheduled protocol. And it was he who read first from the Book of Genesis during their live transmission from lunar orbit that Christmas Eve. Continue reading...

Nine years after his first trip to outer space, Tim Peake is ready to blast off once again. He talks about preparing for the first all-British space mission - and setting his sights on MarsThe astronaut Tim Peake is tracking his cab driver on his phone. The car that will deliver him from our meeting to his next appointment (on a day packed with radio commitments) is late and Peake is calculating the most time-efficient route for us to meander through Soho's traffic, on foot, to reach it. Peake is the seventh UK-born astronaut in space and the first Briton to spacewalk - an unfathomable feat for us, but not for him. Space, he agrees, casting a glance at a printout of the schedule he keeps in his jacket pocket, might be easier to navigate than rush hour on Earth.We have already been chatting for an hour, in a snug above his agent's office. He announced his retirement as a European Space Agency (ESA) astronaut in January 2023, but we're meeting in the wake of news that he is preparing for a return to orbit on the first ever all-British space mission. That mission is due to launch next year and Peake is expected to be announced as the flight's commander within the coming weeks. The radio interviews he's conducting today coincide with a deadline for British businesses to make a case for their science to be included onboard, to be tested in microgravity as a priority for the mission: a strident bid to showcase Britain's Stem capabilities on an outer-world stage.

Rather than stretching to infinity and beyond, the universe may have a topology that can eventually be mappedWe may be living in a doughnut. It sounds like Homer Simpson's fever dream, but that could be the shape of the entire universe - to be exact, a hyperdimensional doughnut that mathematicians call a 3-torus.This is just one of the many possibilities for the topology of the cosmos. We're trying to find the shape of space," says Yashar Akrami of the Institute for Theoretical Physics in Madrid, a member of an international partnership called Compact (Collaboration for Observations, Models and Predictions of Anomalies and Cosmic Topology). In May, the Compact team explained that the question of the shape of the universe remains wide open and surveyed the future prospects for pinning it down. Continue reading...

Exclusive: Massive' discovery raises possibility conditions for life were present almost from dawn of timeAstronomers have detected carbon in a galaxy observed just 350m years after the big bang, in observations that raise the possibility that the conditions for life were present almost from the dawn of time.The observations, made by the James Webb space telescope, suggest that vast amounts of carbon were released when the first generation of stars exploded in supernovae. Carbon is known to have seeded the first planets and is a building block for life as we know it, but was previously thought to have emerged much later in cosmic history. Continue reading...

Before the pandemic, Lucy Keighley ran a gym, worked as a personal trainer and went on gruelling, exhilarating runs. But after three and a half years of illness, she isn't sure she will ever recoverI was incredibly strong and fit," says Lucy Keighley. And she looks it, in the photo she is showing me, taken a few years ago. She is with her best friend, Lorna; they have just completed a 15-mile race on the North York Moors. It was a brutal race," she says. But it was great. I was happy." Today, although it's quite dark in the room (she doesn't get on well with bright light), I can see a tear rolling down her cheek. I don't know if I'm ever going to get back there."Lucy, 49, still runs - across the moors and along the coast - but only in her sleep. I'm so light on my feet. I was never a light-footed runner in real life. But in my dreams I am so light, I can run so far, and it feels joyous." Continue reading...
