A mysterious source has been sending radio signals to Earth from space for decades
An unknown source has been sending radio blasts towards Earth since at least 1988, scientists say. The researchers do not know what object is sending the radio waves towards Earth. The nature of the waves is such that they do not conform with any models that attempt to explain it. For 35 years, the source has been sending out regular 20-minute blasts of energy that vary considerably in their brightness, researchers say. The emissions appear something like the blasts that come out of pulsars or fast radio bursts, which last for milliseconds to several seconds. But the newly discovered source sends radio signals that pulsate on a period of 21 minutes – something previously thought impossible by expected explanations. Pulsars are neutron stars that spin around quickly, throwing out radio blasts as they do. When one crosses Earth, the emissions can be picked up very briefly and brightly, like being in the path of the light from a rotating lighthouse. Scientists believe that process can only work if the magnetic field of the pulsar is strong, and it is rotating quickly enough – if not, there would not be enough energy to see the pulsar from Earth. That has led to the development of the “pulsar death line”, which suggests that sources must be spinning fast and strong enough to be detected. The newly discovered object named GPMJ1839-10, however, is way beyond that death line. If it is a pulsar, then it seems to be operating in ways that scientists thought impossible. It could also be a highly magnetised white dwarf or magnetar, an extra kind of neutron star with incredibly strong magnetic fields. But they do not tend to send out emissions of this kind, researchers believe. The signals have been detected on Earth since at least 1988, scientists found by going through old records, but they had gone unnoticed by those collecting that data. After the source was detected, researchers checked radio archives and found that the source has been repeating for at least 35 years. Yet more discoveries may be made in this way in the future, said Victoria M Kaspi, a professor of physics at McGill University who did not work on the study. “Only time will tell what else lurks in these data, and what observations across many astronomical timescales will reveal,” she wrote in an accompanying article. That might include some explanation of how unusual the newly discovered source is. By examining whether there are is a similar collection of other objects in the data, researchers might be able to understand the mechanisms behind the newly discovered emissions. The findings are reported in a new paper, ‘A long-period radio transient active for three decades’, published in the journal Nature.

7 ways to ease back-to-school worries
School should be the best years of children’s lives – but, as the new term approaches, evidence suggests it’s actually the most worrying time for many kids. The children’s helpline Childline delivered 7,772 counselling sessions about school/education worries last year, with a big increase in calls in the run-up to the start of the new school year. “School is a huge part of a child’s life, so it’s important they feel happy and secure there,” says Childline director Shaun Friel. “We know some children can feel anxious and apprehensive about going back to school, particularly after spending a lot of time away from the classroom due to the summer break. “In fact, our Childline counsellors see a spike in the number of counselling sessions they deliver to children about school worries following the summer holiday season.” Friel says some children feel worried about making friends, getting lost, or the workload at a new school, while others may have concerns about returning to their current school due to friendship issues, fears about upcoming exams, or the recurrence of bullying. “However a child feels about returning to school, we want to remind them that these worries are normal and they aren’t alone,” he stresses. “If any child is feeling apprehensive about going back to school, our trained counsellors are here 24/7 over the phone and online.” As well as counselling, Friel says there are many things both parents and children can do to ease back-to-school anxieties. They include… 1. Writing feelings down Parents can get their child to write down everything they’re looking forward to at school, and everything they’re worried about. “Encourage them to show you the list so you can chat through their concerns, help them cope with their worries and also look at the positives,” suggests Friel. 2. Listening to their concerns If your child has concerns about going back to school, take time to listen to what they’re saying before you jump in to give advice or your opinion, Friel advises: “You could try repeating back what they’ve shared to check you’ve understood their feelings correctly – this will help them to feel really heard.” 3. Discussing practical solutions Once your child has shared any concerns or anxieties about going back to school, you could try talking through some practical solutions, suggest Friel. So, for example, if they’re worried about the amount of homework they’ll have, you could discuss how to break this down each evening and what they could do if they start to feel overwhelmed, like talking to their teacher or you. “You could start by asking them what they think might help them feel better about the situations that worry them,” says Friel. “This can encourage them to learn to think for themselves and feel in more control of the situation.” 4. Reminding them to take their time Remind your child it can take time to adjust to being back at school, and it’s okay if it doesn’t feel comfortable at first, says Friel. “Being back at school will mean a totally different routine, and it’s important to remember that this can take some getting used to,” he stresses. 5. Doing things they enjoy When kids are back at school, making time every day to do something they enjoy can really help to ease anxiety, says Friel. “Whether it’s time in their evening with friends, reading a book or hanging out with their siblings, it’s important to take time out,” he advises. 6. Talking to a trusted adult It’s important children are aware they can and should talk to a safe adult – perhaps a parent, carer, teacher, sibling over the age of 18 or a Childline counsellor – about anything. “No matter what the reason, if a young person is struggling ahead of going back to school, it’s vital they’re encouraged to talk to a safe adult about it,” stresses Friel. “Sharing their feelings with someone they trust will help them feel less alone with their worries, and that adult will be able to support them with this moving forward.” 7. Distracting themselves If children or young people make an effort to keep busy doing something they enjoy, such as playing football or listening to music, this could distract them from their worries, at least for a little while, says Friel. Staying connected with friends and family, whether that be online or in person, or doing some physical activity like going for a walk or taking part in a sport, can also be a good distraction technique. Young people can contact Childline, which is run by the NSPCC and supported by the People’s Postcode Lottery, on 0800 1111 or via 1-2-1 chat on Childline.org.uk Read More Charity boss speaks out over ‘traumatic’ encounter with royal aide Ukraine war’s heaviest fight rages in east - follow live What is the best type of facial for your age range?

Hilary Duff admits she ‘sometimes’ follows Gwyneth Paltrow’s controversial morning coffee diet
Hilary Duff has revealed that she often follows Gwyneth Paltrow’s controversial coffee-only diet in the morning. The 35-year-old actor recently appeared on the Lipstick on the Rim podcast, where she spoke about her beauty secrets and makeup regimen. While sharing details about her daily routine, the Lizzie McGuire star admitted that she tends to follow Goop founder’s morning ritual. “I wake up really hungry,” Duff told podcast host Molly Sims on Tuesday 9 May. “Sometimes I try to – you know, Gwyneth’s in trouble for saying this – but sometimes I try to just drink coffee in the morning and starve off my hunger.” The 50-year-old lifestyle guru recently turned heads when she detailed her wellness routine, which included drinking coffee or “celery juice with lemon or lemon water” in the mornings so that she won’t “spike [her] blood sugar”. Paltrow recently sparked backlash when she described her daily eating habits during a March episode of The Art of Being Well with Dr Will Cole podcast. The Oscar winner began by explaining that she usually eats dinner “early in the evening” so that she’s “really done eating by 7pm.” “And then I do a nice intermittent fast until I usually eat something at about 12pm,” Paltrow continued. Then, she tends to have coffee, or “celery juice with lemon or lemon water” in the mornings, as she doesn’t want something that will “spike [her] blood sugar” before exercising with one hour of pilates or walking. Her afternoon meals consist of “bone broth for lunch a lot of the days,” while she eats “according to paleo” for dinner. Paltrow’s daily routine sparked considerable criticism, as many dieticians claimed it resembled disordered eating habits. The Iron Man star later clarified her podcast remarks, noting that she has been working with her doctor. @dearmedia #gwynethpaltrow shares her daily wellness routine on The Art Of Being Well, listen now ? #wellnessroutine #healthandwellness #healthylifestyle #routines #goop #podcastclips ♬ Aesthetic - Tollan Kim “This is a person I’ve been working with for over two years now to deal with some chronic stuff,” Paltrow explained in a post on her Instagram Story, adding that she’s been experiencing post-Covid symptoms. “The way it manifests for me is very high levels of inflammation over time, so I’ve been working with Dr Cole to really focus on foods that aren’t inflammatory.” “This was a transparent conversation with me and my doctor,” she said. “It’s not meant to be advice for anyone else. It really just works for me, and it’s been very powerful and very positive.” Paltrow also informed critics that the foods she mentioned on the podcast are not what she eats every day, adding: “And by the way, I eat far more than bone broth and vegetables. I eat full meals, and I also have a lot of days of eating whatever I want. And eating, you know, French fries and whatever.” Despite sometimes following Paltrow’s morning routine, Duff admitted on the Lipstick on the Rim podcast that she still eats “lots of calories” when packing school lunch for her three children. The former child star shares daughters Banks, four, and Mae, two with husband Matthew Koma. She also shares 11-year-old son Luca with ex-husband Mike Comrie. “If we’re being honest, yeah, I eat a chicken nugget in the morning while I’m packing lunches and there’s one left over,” she confessed. “Pop it down the hatch!” In addition to the occasional chicken nugget, some of the How I Met Your Father star’s favourite foods included “cauliflower rounds” in the air fryer, topped with an avocado, fried egg, or vegan sausage. As for her fitness routine, Duff shared that she works out with a trainer and focuses on high-intensity interval training (HIIT) workouts.
