Summer Solstice 2025: What is it and how is it celebrated?
The summer solstice is the longest day of the year, meaning it's the day that we get the most amount of daylight.In the northern hemisphere - where the UK is located - it will occur on Saturday 21 June 2025.The summer solstice also marks the end of spring and the official start of summer.It is the opposite of the winter solstice, which is the shortest day of the year and has the fewest hours of daylight.
Why is the Summer Solstice the longest day of the year?
We get the most hours of daylight on this day because of the position of the Earth in relation to the Sun.It happens when the Earth's geographical pole - on either the northern or southern hemisphere - becomes most inclined towards the Sun.When the summer solstice takes place in the northern hemisphere, the Sun will reach its highest possible point. For the UK, this will happen at 3.42am.Because of this, the day ends up being the sunniest day of the year. Even if it's wet or cloudy that day, we will technically get the most amount of sunshine.Because the Earth turns on a slight tilt, the amount of sunlight that reaches different areas of Earth changes throughout the year, as we orbit the Sun.The axis is the point at which the Earth turns - ours isn't perfectly straight up, so the Earth rotates at a tilt.
Why doesn't the Sun set in some parts of the world?
Around the time of the summer solstice, areas of Norway, Finland, Iceland, Greenland, Alaska and other polar regions experience midnight sun - or 24 hours of sunlight.This is because the Sun does not set below the horizon.In the Arctic Circle, the Sun does not set at all. The world 'solstice' comes from the Latin solstitium meaning 'Sun stands still',
What does Stonehenge have to do with the Summer Solstice?
Summer solstice is celebrated by people across the world.In the UK, many gather at Stonehenge, which is believed to have been used as an important religious site by early Britons some 4,000 years ago.On the summer solstice, the central Altar stone at Stonehenge aligns with the Heel stone, the Slaughter stone and the rising Sun to the north east.Every year, lots of people gather to celebrate the solstice, with pagan songs and dancing.

Chronic fatigue is not in your head, it's in your blood
People with ME and chronic fatigue syndrome have major differences in their blood compared with healthy individuals, experts have of Edinburgh researchers said their findings could pave the way for a "game-changer" diagnostic Chris Ponting said: "For so long people with ME/CFS have been told it's all in their head. It's not. We see it in their blood."The study used data from the UK Biobank – a health database of over half a million people – to compare 1,455 ME/CFS patients with 131,000 healthy individuals. The research showed the results were mostly unaffected by activity university team said the volume and consistency of the blood differences support their long-term goal of developing a diagnostic blood Dr Sjoerd Beentjes told BBC Radio's Good Morning Scotland: "One thing that our evidence points at is that ME is very much a condition in the blood."Perhaps previously held perspectives are not quite the case."It is really not due to inactivity and we hope that this helps with problems where individuals are disbelieved of their symptoms." What are the symptoms of ME? The largest ever biological study of ME/CFS - which is estimated to affect 50,000 people in Scotland - identified consistent blood differences associated with chronic inflammation, insulin resistance, and liver main feature of the condition is post-exertional malaise (PEM) - a delayed and dramatic worsening of fatigue that comes after minor physical symptoms include pain, brain fog and tiredness that does not improve with rest. Causes are unknown and there is currently no diagnostic test or Beentjes also said ME was a "female bias" condition with the ratio of patients estimated to be 3:1. The Edinburgh researchers examined more than 3,000 blood-based biomarkers and accounted for differences in age, sex, and activity results were replicated afterwards using data from the US Prof Chris Ponting, of the university's MRC human genetics unit, said: "For so long people with ME/CFS have been told it's all in their head. "It's not. We see people's ME/CFS in their said the evidence should "dispel any lingering perception that ME/CFS is caused by deconditioning and exercise intolerance".

28 Years Later review: Another relentless apocalyptic horror from Danny Boyle
Danny Boyle and Alex Garland have produced another horror masterpiece with 28 Years Later , the third instalment in the '28 Days' universe. The director and writer were not heavily involved in the followup, '28 Weeks Later', but they make a triumphant return in the new film. It is partly shot on iPhones, something introduced by Boyle with 28 Days later, and this contributes to the frantic and anxiety-inducing pace of the film as our new protagonisted go up against the infected. Advertisement This includes new additions to the creatures that were produced about the rage virus, including the terrifying 'alphas' who are able to effortlessly rip people's heads off. While the film is full of the action we saw in its two predecessors, Boyle and Garland manage to include a commentary on British society. With the rest of the world operating as normal as the 21st century rages on, Britain is quarantined to keep the infected from reaching the rest of the world, with navies patrolling its waters. In a remote island, survivors life a primitive but peaceful and safe existence, accessible to the foreboding 'mainland' only by a causeway only accessible when the tide recedes. Advertisement With Britain stuck in the past, it's hard to avoid the intended Brexit parable. This is only accentuated by Boyle's use of black and white World War footage, and a haunting score which includes 1903 poem " Boots " by Rudyard Kipling , recited by American actor Taylor Holmes. Jamie (Aaron Taylor-Johnson) brings his 12-year-old son Spike (Alfie Williams) to the mainland to get his first kills in an almost ritualistic expedition, against the advice of the communiy's elders who warn that Spike is far too young. Ralph Fiennes in 28 Years Later. The horrors they encounter leave a mark on father and son, but Spike is determined to return to seek a cure for his seriously ill mother Islan ( Jodie Comer ). This is where we once again enconter Dr Ian Kelson (Ralph Fiennes). A key character in the first film, Dr Kelson steals the show once again. His descent into madness, looking like Colonel Kurtz in Apocalypse now, isn't quite what it seems, despite the temple of skulls he has amassed. The ending sets things up nicely for 28 Years Later: The Bone Temple, which is due for release in January 2026.

New blood test could transform chronic fatigue syndrome diagnosis
Scientists have identified a potential blood test that could provide the first reliable diagnosis for myalgic encephalomyelitis (ME), also known as chronic fatigue syndrome (CFS). Currently, ME is diagnosed by ruling out other illnesses, a lengthy process that can take years for patients. Researchers at the University of Edinburgh compared blood samples from ME patients and healthy individuals, identifying 116 "biomarkers" linked to chronic inflammation, insulin resistance, and liver dysfunction. This breakthrough challenges the perception that ME is psychological, with Professor Chris Ponting stating that evidence is visible in patients' blood. While promising, the research is still in its early stages, and further work is required before a definitive diagnostic test can be guaranteed.
