Internet blackout? Scientists warn solar storm could crash digital world
Although such powerful solar flares haven't been recorded in over a thousand years, experts say a similar event today could pose an unprecedented threat to global systems dependent on electricity and digital connectivity.
This type of solar event is known as a 'Miyake event,' named after Japanese researcher Fusa Miyake, who in 2012 identified an unusual spike in carbon-14 levels in tree rings dating back roughly 1,250 years—evidence of a colossal solar explosion that once sent high-energy particles hurtling toward Earth.
Professor Matthew Owens of the University of Reading explained that a modern Miyake event "could burn out power transformers and collapse entire energy grids,' adding that restoring these networks would be a lengthy process due to the time required to produce and replace damaged transformers.
What would happen if Earth were hit by a severe solar storm?
Widespread collapse of electrical power grids
Internet and telecommunications outages
Disruption of satellites and air/sea navigation systems
Shutdown of water treatment and sanitation facilities
Spoilage of refrigerated and stored food due to power cuts
Dangerous radiation levels at high altitudes
Depletion of the ozone layer by up to 8.5%, triggering major climate effects
Rare auroras visible in unusual locations around the globe
Scientists warn that the warning time for such an event would be limited to just 18 hours—insufficient for global preventive measures.
According to researchers, a Miyake event could be at least ten times more powerful than the infamous 1859 Carrington Event, which disrupted telegraph systems and caused auroras near the equator.
A recent study by the University of Queensland concluded that a similar event today could deal a severe blow to the digital and technological world, triggering long-term internet outages and massive disruptions to the global economy, especially due to the fragile nature of digital infrastructure and the difficulty of predicting such cosmic disasters.

NASA Crew-10 astronauts depart space station after five-month mission
Ammon News - Four astronauts from NASA's Crew-10 mission departed the International Space Station on Friday aboard a SpaceX Dragon capsule, heading for a splashdown off the U.S. West Coast on Saturday morning after a five-month crew rotation mission at the orbiting lab. U.S. astronauts Nichole Ayers and Anne McClain, the Crew-10 commander, boarded the gumdrop-shaped Dragon capsule on Friday afternoon along with Japanese astronaut Takuya Onishi and Russian cosmonaut Kirill Peskov ahead of a 17.5-hour trek back to Earth to a splashdown site off the California coast. The four-person crew launched to the ISS on March 14 in a routine mission that replaced the Crew-9 crew, which included NASA astronauts Butch Wilmore and Suni Williams, the astronaut pair left on the station by Boeing's Starliner capsule. Astronauts arrive before launch to the International Space Station, in Cape Canaveral Five months after the Starliner mission's conclusion, Wilmore this week retired from NASA after a 25-year career in which he flew four different spacecraft and logged a total of 464 days in space. Wilmore was a key technical adviser to Boeing's Starliner program along with Williams, who remains at the agency in its astronaut corps. The four astronauts in the Crew-10 capsule are scheduled for a splashdown in the Pacific Ocean at 11:33 a.m. ET (1533 GMT) Saturday. NASA said they are returning to Earth with "important and time-sensitive research" conducted in the microgravity environment of the ISS during the 146-day mission. The astronauts had over 200 science experiments on their to-do list. Reuters

Internet blackout? Scientists warn solar storm could crash digital world
A team of scientists has issued a stark warning about the possibility of a massive solar storm that could hit Earth without warning, causing widespread damage to satellites, power grids, and the digital infrastructure that modern society heavily relies on. Although such powerful solar flares haven't been recorded in over a thousand years, experts say a similar event today could pose an unprecedented threat to global systems dependent on electricity and digital connectivity. This type of solar event is known as a 'Miyake event,' named after Japanese researcher Fusa Miyake, who in 2012 identified an unusual spike in carbon-14 levels in tree rings dating back roughly 1,250 years—evidence of a colossal solar explosion that once sent high-energy particles hurtling toward Earth.

Discover the Benefits of Omega-3 and Signs of Deficiency in the Body - Jordan News
From reducing the risk of heart disease and preventing dementia to alleviating joint pain, Omega-3, commonly found in fatty fish such as salmon and sardines, is often praised for its significant health benefits. اضافة اعلان According to a report by The Telegraph, the latest research highlighting the power of Omega-3 is the Do-Health clinical trial, aimed at determining how to extend the "health span" (our active, healthy life). The Do-Health study recruited over 2,000 healthy people over the age of 70 from five European countries and measured the impact of various interventions. It was found that daily Omega-3 supplements reduced the rate of disease in participants by 13%. In a new paper published this month, the research team also concluded that those who took Omega-3 acids for three years aged three months slower than those who did not, based on biological markers. According to Perveen Yacoub, an expert in Omega-3 acids and professor of nutritional physiology at the University of Reading, our interest in these fatty acids dates back to the 1950s, when researchers traveled to Greenland to study the diet of the Inuit (Eskimos). Yacoub said, "They consumed enormous amounts of whale and seal meat, which was very rich in Omega-3s. The first observation was that the Inuit had very long bleeding times if they cut their skin, indicating their blood was very thin." She added, "The second observation was that, despite consuming high-fat whale and seal meat, they had very low rates of cardiovascular disease." In some way, this high-fat diet didn't cause the chronic diseases linked to obesity that we see today. While there is ample evidence of the benefits, there is still no recommended dosage, and available supplements vary significantly in concentrations. The UK's National Health Service guidelines suggest consuming two portions of fish per week, one of which should be oily fish (rich in Omega-3). What is Omega-3? Yacoub explained that Omega-3 is an extraordinary family of fatty acids, with the three main types being ALA, DHA, and EPA. It is widely believed — though not conclusively proven — that DHA is more important for brain function, while EPA plays a larger role in cardiovascular health. In fact, only EPA and DHA are found in "oily" fish. Nutritional expert Nicola Shubrook explained, "We need a balance of fats in our diet. Humans evolved on the edges of land masses, eating fish, but the shift to agriculture has meant our diets now contain more Omega-6 fats (from vegetable oils)." She added, "The ideal ratio of Omega-6 to Omega-3 should be 3:1." What Are the Other Four Health Benefits of Omega-3? Cardiovascular Health: Reduces the risk of clotting and lowers triglycerides (a type of fat in the blood). Reduces Inflammation: May improve several conditions related to inflammation, including rheumatoid arthritis, eczema, psoriasis, and dry eye disease. Improves Mood and Cognitive Function. Reduces Deaths from All Causes. Signs of Omega-3 Deficiency Jeff Mullan, chief medical officer at Human People and a longevity specialist, highlighted that "Omega-3 is essential for the gray matter in your brain, as every cell in your body contains Omega-3 in its membrane." He added, "Omega-3 also plays a role in regulating blood clotting and our inflammatory responses. This makes it vital for the heart, skin, brain, joints, and nearly every system in the body." Signs of Omega-3 deficiency include: Dry, brittle skin. Rough skin (keratosis pilaris) on the upper arms, which is a common early sign. Dry eyes. Joint pain. Stiffness and slow recovery after exercise. Depression and anxiety. Cod Liver Oil White fish store fats in their liver rather than in their flesh, so cod liver oil is another source. Yacoub stated, "Generations who grew up consuming cod liver oil swear by its beneficial effects, especially in maintaining joint flexibility."
