Scroll charred by eruption of Vesuvius finally reveals secrets

Times06-05-2025
An ancient papyrus scroll long believed to have been rendered 'unreadable' by the eruption of Mount Vesuvius nearly 2,000 years ago, is finally yielding its secrets.
The scroll was found in the remains of one of the most opulent villas in the Roman town of Herculaneum, about 12 miles from Pompeii. When Vesuvius erupted, the building was buried under layers of volcanic ash and mud. The papyrus, along with hundreds of others, was 'carbonised'.
Heated to extreme temperatures in the absence of oxygen, it came to resemble a badly burnt sausage, black and too brittle ever to be unrolled.
The title of the carbonised scroll, with transcribed letters overlaid, was deciphered by two graduate students at the University of Wurzburg

Scientists investigate surge in whale and dolphin strandings in Scotland

There has been an "exponential" increase in marine mammal strandings in waters around Scotland, scientists have number of whales, dolphins and porpoises getting into difficulty has risen from about 100 a year to more than 300 over a 30-year at the University of Glasgow said possible causes include chemical, plastic and noise pollution and accidental entanglements in fishing than 5,140 stranded marine animals were recorded in the study between 1992 and 2022. Strandings happen when a marine animal becomes stuck in shallow water or on a shoreline. It often results in death or study, published in Scientific Reports, found a steep rise in strandings involving common dolphins and baleen whales - filter-feeding species that include minke and humpback whales. The new research used data gathered by the Scottish Marine Animal Stranding Scheme (SMASS).Harbour porpoises accounted for more than half all the strandings - 2,676 - followed by pelagic dolphins with 1,217 incidents.A total 494 of common dolphins and 479 baleen whales had stranded over the 30-year period, according to the scientists said deep divers, such as sperm whales, and pelagic dolphins showed a steadier increase in strandings since the 1990s. Researchers said while exact causes were difficult to pinpoint, they agreed that human activities were likely impacting on said "predominant threats" were declining fish stocks, noise pollution, and entanglements with lost fishing risks were habitat change due to warming sea temperatures, and chemical and plastic pollution. Rachel Lennon, lead author and PhD researcher at the University of Glasgow, said: "Fisheries interactions are recognised as a critical threat for marine mammals, especially for baleen whales in Scotland. "As populations begin to recover from the impacts of historic whaling, reports of entanglement have increased. "While determining the exact causes of strandings can be complex, identifying these emerging trends provides a vital starting point for targeting future research."A number of initiatives have been set up to tackle the threat of entanglements, including the Scottish Entanglement Alliance (Sea).The coalition of conservation groups, rescue teams and fishermen has sought to find best practices to avoid entanglements, and the most effective responses to any incidents. Where do strandings happen? Dr Andrew Brownlow, of SMASS, said: "This research shows how reports of stranded marine animals - many made by members of the public - can offer important clues about the overall health of our seas. "These animals act as sentinels of the ocean, and rising numbers of strandings may be an early warning that something is changing in the marine environment."

Groundbreaking new cancer detection technique replaces radioactive tracers with diamond sensor

Scientists have developed a diamond -based sensor that could make it easier for doctors to detect the spread of cancer. Researchers at the University of Warwick have created a handheld device that is designed to trace tiny magnetic particles injected into the body. The scientists said this offers a non-toxic alternative to radioactive tracers and dyes currently used in hospitals. Metastasis, when cancer cells spread from the original tumour to other parts of the body, is one of the most serious challenges in cancer treatment. Doctors often rely on tests to see whether the cancer has reached the lymph nodes – the areas of tissue that filter fluid in your body for harmful substances – which can guide decisions about surgery and further care. The findings, published in Physical Review Applied, describe how diamonds can be used to build a highly sensitive sensor capable of identifying the magnetic tracer fluid injected into a tumour. This fluid, made up of iron oxide nanoparticles, travels through the body alongside cancer cells, revealing whether they have reached the lymph nodes, the researchers said. Lead author Alex Newman, a PhD student in Warwick University's physics department, said the new tool could improve the way doctors find cancer in keyhole and endoscopic surgery. 'There is a real demand for versatile non-toxic means of finding cancer,' he said. 'For this new diamond-based sensor, we managed to get the size of the sensor head down to just 10 millimetres, which means it is the first diamond sensor to be able to detect magnetic tracer fluid while being small enough for endoscopic use and keyhole surgery.' Mr Newman added that the device was extremely sensitive, capable of detecting just one hundredth of the typical dose of magnetic tracer fluid. The design uses a diamond measuring only half a cubic millimetre alongside a small permanent magnet, the scientists said They added that this compact structure means there is no need for bulky electronics, allowing the sensor to be used by hand in operating rooms. Professor Gavin Morley, who leads the research group, said the breakthrough was possible thanks to nitrogen vacancy centres inside the diamond. 'These allow the diamond to detect very small changes in the magnetic field and give the diamonds a lovely pink colour,' he said. He added that the technology could also have uses beyond medicine, including in spacecraft and fusion power. Current techniques for tracing cancer cells rely on radioactive tracers, which not all hospitals can access, or blue dyes, which trigger allergic reactions in some patients, the researchers said. Clinicians involved in this new project believe the new diamond sensor could help avoid these complications. Stuart Robertson, a consultant breast cancer surgeon at University Hospitals Coventry and Warwickshire, said he was already using magnetic localisation in his work. He added that it offers more advantages over traditional techniques. Researchers say the device could eventually be applied to various cancers, including lung, liver, colorectal and oesophageal tumours.

Why you're struggling to stay awake during the day - and how to feel more alert

For millions of people, fighting to stay awake at their desk, on the commute home, or even mid-conversation is a daily struggle. Now, scientists believe the reason why some people are far more prone to overwhelming drowsiness may be due to their diet and hormones. Researchers have identified seven metabolites, which are naturally occurring chemicals in the blood, that appear to influence a person's risk of Excessive Daytime Sleepiness (EDS). EDS, also known as hypersomnia, affects around one in four Britons, and is linked to a higher risk of cardiovascular disease, obesity and diabetes. A new study, emerging from Mass General Brigham and Beth Israel Deaconess Medical Center in the US, suggested that diet and hormones may affect hypersomnia. The findings, published in Lancet eBioMedicine, used blood samples from more than 6,000 people who took part in a long-term health study, alongside questionnaires assessing how often participants fell asleep during the day. Seven metabolites were associated with EDS, with three additional metabolites found to vary by sex, the study found. These include tyramine, which is present in fermented and overripe foods. This was linked to increased drowsiness, particularly in men. Foods high in tyramine: Aged cheeses Cured and smoked meats Fermented foods Overripe fruits Pickled foods Red wine The researchers also found that sex steroid metabolites, such as progesterone, were associated with sleep-related processes, including melatonin production. On the other hand, omega-3 and omega-6 fatty acids, commonly found in Mediterranean-style diets, were linked to a lower risk of excessive sleepiness, according to the research. Foods high in omega-3 and omega-6 fatty acids: Fish such as salmon, mackerel, sardines and tuna Shellfish Walnuts Flaxseeds Eggs Poultry Whole-grain breads and cereals Dr Tariq Faquih, the study's lead author, said: 'Our study suggests diet and genetics may play an important role in EDS. As we learn what's happening biologically, we are beginning to understand how and why EDS occurs, the early signs that someone might have it, and what we can do to help patients.' The researchers said the results point to potential treatment targets for EDS, suggesting dietary changes and new medications may be possible. According to the NHS, hypersomnia is different from simply feeling tired. People with the condition may regularly nap during the day, fall asleep without warning, or still sleep for long hours at night. It can sometimes be linked to conditions such as narcolepsy, sleep apnoea, restless legs syndrome, depression, or chronic fatigue syndrome. The NHS advises improving sleep habits by going to bed at the same time each night, cutting back on alcohol and caffeine, creating a peaceful sleep environment and avoiding late-night working.
