Sex drug Viagra has surprising new health benefit and could help 3 million ageing Brits, say scientists
The little blue tablet was found to increase production of vital bone cells — so could one day prevent back pain and fractures in old age.

Researchers found sildenafil, which is branded as Viagra, helped human stem cells transform into osteoblasts, the bone-building cells.
These are vital as the human skeleton regenerates and is completely replaced roughly once every ten years.
As we age, we lose more bone than we build, increasing the risk of breaks or osteoporosis, which makes bones brittle and painful.
The Peking University team's follow-up tests on mice also suggested sildenafil would prevent bone loss.

'Sildenafil enhanced stem cell osteogenic differentiation and inhibited bone loss — it may usefully treat osteoporosis.'

Disturbing Ancient Egyptian graves reveal brutal treatment of corpses 5,000 years ago including shock teen girl's burial
ARCHAEOLOGISTS have uncovered a disturbing Ancient Egyptian burial practice that saw people dismembered before being put to rest. The discovery offers a rare insight into the spiritual life of villagers more than 5,000 years ago - and may even mark the beginning of religion for the ancient pharaohs. 3 Using artificial intelligence (AI) and machine learning, researchers analysed patterns among more than 900 tombs across the 74-acre Adaiima site Credit: Alcouffe, A., Duchesne, S., Tupikova, I. et al./ Journal of Archaeological Method and Theory Researchers found the remains of a teenage girl whose arm had been deliberately severed after her death and positioned to match her left arm. The girl's left arm was bent unnaturally in a more than 90degree angle and tucked in very tightly. The limb was removed near the lower part of the upper arm and forearm, possibly done using an axe. The muscles were most likely sliced with a flint blade, according to researchers. READ MORE ON ANCIENT EGYPT Her severed arm was carefully arranged to appear almost intact, with the hand placed beside the forearm. Buried in the Adaiima cemetery on the west bank of the Nile river, the remains date back to between 3300 to 2700 BC. The girl's body was carefully aligned with the setting sun on the winter solstice, while her coffin also pointed towards the rising of Sirius, the brightest star in the sky. Celestial alignments, and other symbolic gestures, likely influenced the religious traditions later embraced by Egypt's first pharaohs who emerged between 100 and 400 years later. Most read in Science 3 Buried in the Adaiima cemetery on the west bank of the Nile river, the remains date back to between 3300 to 2700 BC Credit: Getty Her burial may also be the earliest sign of the Osiris and Isis myth - where the goddess Isis reassembles the dismembered body of Osiris beneath the rising Sirius. The tale is thought to symbolise death, rebirth, and cosmic order. Ancient Egyptian Tombs: Over a Thousand Mummies Unveiled The cemetery her remains were found in is one of Egypt's oldest and most thoroughly studied, and paints a detailed picture about how funerary practices changed over time. Using artificial intelligence (AI) and machine learning, researchers analysed patterns among more than 900 tombs across the 74-acre Adaiima site. Another coffin that was positioned to catch the winter sun contained a woman buried with ornate jewelry and pottery. A third grave, also belonging to a woman, faced the summer sunset and contained a ceremonial staff and plant-fiber wig. The study suggests these early burials shaped the mythology later adopted by Egypt's ruling elite - from their sky-based alignments to their ritual gestures, such as dismemberment. Older graves were placed around earlier, astronomically-aligned tombs, suggesting those burials held continued to hold religious or ancestral significance over the years. Ivory boat models and fine coffins were found with remains researchers believed once belonged to individuals of higher status or spiritual importance. Similar to the dismemberment, a singular bone belonging to a child was found placed on the chest of an adult in a later tomb. In the myth of Osiris, Isis gathers the scattered body parts of her murdered husband after he is slain by his jealous brother, Set. "Sepdet, which we know as Sirius, was believed to be the appearance of Isis in the sky," the study said. "When the state emerged, it did not create religion from scratch. "It absorbed long-standing practices and reworked them into royal narratives." 3 The limb was removed near the lower part of the upper arm and forearm, possibly done using an axe Credit: Alcouffe, A., Duchesne, S., Tupikova, I. et al./ Journal of Archaeological Method and Theory

Are YOU one of the ‘missing millions' at risk of heart attacks due to undiagnosed silent killer – the 4 signs to know
MILLIONS of Brits have undiagnosed high blood pressure and are at risk of heart attacks and strokes, the British Heart Foundation warns. The charity said more than 125,000 deadly emergencies could be prevented in the next decade if doctors tracked down people unaware they are at risk. 1 High blood pressure becomes more common with age (stock image) Credit: Getty It estimates five million people are not getting the right treatment. The BHF estimates 16million people – about a third of adults – have it, but around half are not getting treatment and five million don't even know they have it. Untreated, it is a leading cause of heart attacks and strokes and accounts for about half of them. Chief medical officer Professor Bryan Williams said: 'This is a powder keg for the nation's future health. 'Making sure these people are identified and treated is critical. 'Huge gains can be made by reimagining how we detect and treat common risk factors for cardiovascular disease such as high blood pressure. 'But at the moment, millions of people are still living undiagnosed with these conditions, which raise the risk of serious illness such as heart attack and stroke.' Most read in Health Heart diseases are the leading cause of death in the UK, on a par with cancer. High blood pressure usually does not cause any symptoms but it is easily detected with routine health checks. What is high blood pressure and what is a normal reading? Some people do show signs of illness and they can include: Headaches Blurred vision Nosebleeds Chest pains How to lower blood pressure Persistent high blood pressure (hypertension) puts extra strain on your blood vessels, heart and other organs and it can raise your risk of serious conditions like heart disease, heart attacks and stroke. Here's how to reduce it. Reduce salt Adults are recommended to limit their salt to 6g per day (around one level teaspoon) to avoid health consequences including high blood pressure. The top tip is to swap out table salt, according to the Salt Substitute and Stroke Study, replacing it with a reduced sodium and added potassium alternative. Cut down on alcohol Excessive boozing can narrow the blood vessels, which raises the risk of hypertension. Official drinking guidelines advise that people should not regularly drink more than 14 units a week to keep health risks from alcohol low. Get moving Exercise is good for the heart and the blood vessels. Although the guidelines recommend 150 minutes of activity per week, if you're currently very inactive, just a walk to the shop every day is better than nothing, and you can work up from there. Studies suggest that isometric exercises - when you hold the body in one position without moving, such as a wall squat or plank - are best for lowering blood pressure. Stop smoking Smoking cigarettes is a killer. It makes the arteries sticky and narrow, which can cause blockages. While smoking is not a direct cause of high blood pressure, it can cause an instant rise to pressure, heart rate and reduce the amount of oxygen that gets to the body's cells. Skip coffee Sadly, caffeine can cause a short, but dramatic increase in your blood pressure - even if you don't have high blood pressure. Therefore cutting back on coffee is recommended as a lifestyle tip for those with hypertension. Lose weight The above tips can help you to lose weight, which is beneficial because being overweight in itself is a risk factor for hypertension. Being overweight forces your heart to work harder to pump blood around your body, which can raise your blood pressure. The only way of knowing whether you have high blood pressure is to have a blood pressure test. All adults over 40 years old are advised to have their blood pressure checked at least every five years.
