A hearing aid before the age of 70 can dramatically reduce risk of dementia, new research finds
People who use a hearing aid before the age of 70 can dramatically reduce their risk of dementia, new research shows. Dementia, which is the loss of cognitive functioning, affects more than six million Americans and leads to more than 100,000 deaths each year, according to the National Institutes of Health. As the U.S. population ages, dementia cases are expected to double by 2060, NIH says. Age-related hearing loss is a risk factor for developing dementia, and a research letter published in JAMA Neurology on Monday found that using hearing aids could reduce this risk. After studying nearly 3,000 participants over up to two decades researchers found those with hearing loss who used hearing aids had a 61 percent lower risk for dementia among those younger than 70 years at the time of their hearing loss diagnosis. 'This finding highlights the importance of early intervention for HL [hearing loss] for possible prevention of dementia,' the authors of the study wrote. But the study noted only 17 percent of people with moderate to severe hearing loss use hearing aids. UCLA Health gave three possible theories for the link between hearing loss and dementia including that hearing loss causes the brain to deteriorate faster. Additionally, your brain works harder to understand conversation when you can't hear well. Straining your brain regularly like this can impact your cognitive function. Hearing loss can also limit your social engagement as conversing in noisy environments is less enjoyable. Your brain may struggle to be intellectually stimulated without socialization. Age-related hearing loss affects one in three people older than 60, according to the American Academy of Audiology. One in two people older than the age of 85 has hearing loss. Common signs of hearing loss include asking people to repeat things, difficulty hearing and understanding speech in noisy settings, and turning the TV or radio up louder than normal. The American Academy of Audiology warns untreated hearing loss can be connected to cognitive decline as well as depression, anxiety, paranoia and poor social relationships.

Rare ‘Evil Twin Black Moon' that only occurs every three YEARS due in days as stargazing spectacle linked to ‘end times'
A RARE "black moon" linked to the biblical prophecy of the "End of Time" is expected to show up in the night sky over the weekend. The astronomical spectacle, also known as the Ominous "evil twin" of a new moon, occurs once every three years. 3 3 The calendar quirk occurs when a second new moon rises within a single calendar month. Unlike a full moon, a new moon passes between Earth and the sun, meaning the side facing our planet remains in shadow and is invisible to the naked eye. This means stargazers and astronomy fanatics will not be able to see the spectacle. However, a pitch-dark sky would be the perfect time for enjoying the summer stars - and even the Milky Way galaxy. While the celestial event is a natural phenomenon, it has been widely linked to biblical passages such as Mark 13:24, according to the Daily Mail. It says: "The sun will be darkened, and the moon will not give its light." According to the prophecy, such events occur during the "end of time", a period of significant events leading up to the return of Jesus Christ and the establishment of God's eternal kingdom. However, scientists and astronomers were quick to debunk superstitious claims. Walter Freeman, associate teaching professor of physics at Syracuse University, said: "A black moon is just a second new moon that happens in one calendar month. "If a new moon occurs near the beginning of the month, the next one can happen before it's over. What is a Blue Supermoon? "From a scientific perspective, this is no different than any other new moon." It comes after a stunning new Nasa clip captured the moment a rare black hole gobbled up a star and caused an earth-shattering explosion. The clip shows the rare moment that the suspected intermediate-mass black hole (IMBH) HLX-1 ripped apart the star, triggering the almighty explosion. Black holes come in a range of sizes, but can be up to 40 billion times bigger than the Sun, Live Science reports. According to Live Science, IMBHs are hard to spot and often confused with clusters of smaller black holes left over from collapsed stars. Researchers also think they may hide behind small groups of stars that closely orbit them without being ripped apart. Meanwhile, a mysterious interstellar object blazing through our solar system could be a piece of "possibly hostile" alien technology, according to a controversial new study. The Moon – our closest neighbour explained The Moon is a natural satellite – a space-faring body that orbits a planet It's Earth's only natural satellite, and is the fifth biggest in the Solar System The Moon measures 2,158 miles across, roughly 0.27 times the diameter of Earth Temperatures on the Moon range from minus 173 degrees Celcius to 260 degrees Celcius Experts assumed the Moon was another planet, until Nicolaus Copernicus outlined his theory about our Solar System in 1543 It was eventually assigned to a "class" after Galileo discovered four moons orbiting Jupiter in 1610 The Moon is believed to have formed around 4.51billion years ago The strength of its gravitational field is about a sixth of Earth's gravity Earth and the Moon have "synchronous rotation", which means we always see the same side of the Moon – hence the phrase "dark side of the Moon" The Moon's surface is actually dark, but appears bright in the sky due to its reflective ground During a solar eclipse, the Moon covers the Sun almost completely. Both objects appear a similar size in the sky because the Sun is both 400 times larger and farther The first spacecraft to reach the Moon was in 1959, as part of the Soviet Union's Lunar program The first manned orbital mission was Nasa's Apollo 8 in 1968 And the first manned lunar landing was in 1969, as part of the Apollo 11 mission The research, from a small group of scientists including a renowned alien-hunting Harvard University astronomer, argues that object 3I/ATLAS is actually an extraterrestrial probe in disguise. On 1 July, astronomers spotted a highly unusual object zooming towards our Sun at roughly 245,000 kilometres per hour - or 68km a second. With a "short tail" and a "fuzziness" around it, astronomers declared it an icy comet - and the fastest rock our solar system has ever seen. Judging by its bizarre orbit, experts determined that the super-fast space traveller had come from outside our solar system. That would make it the third interstellar object to pass Earth on record, following the rare visits of the famous 1I/ʻOumuamua asteroid in 2017 and 2I/Borisov in 2019. But Harvard astrophysics professor Avi Loeb and his colleagues suggest it could be something more advanced than an interstellar rock. 3

Solar may account for half of new US electricity added this year, EIA says
NEW YORK, Aug 20 (Reuters) - Developers are on track to add 33 gigawatts of solar power in the U.S. this year, accounting for about half of the total new electricity generating capacity planned for the country in 2025, the Energy Information Administration said on Wednesday. If the plans are realized, large-scale solar power additions in the U.S. would reach a record high, said the EIA, which based its analysis on a survey of developers. New battery storage, which stores electricity from solar farms and other energy sources, may also hit a yearly record in 2025. Wind and natural gas power plants accounted for the rest of the capacity additions, the EIA said. Solar energy does not produce global warming emissions. That makes it central to plans by U.S. states to decarbonize, while also meeting record-high electricity demand brought on by Big Tech and other expanding industries. Many of the federal government financial incentives that propelled the development of solar power over the last several years, however, will disappear under the administration of President Donald Trump, adding uncertainty to future development of the technology. Texas, which last year surpassed California as the state with the most large-scale solar capacity, accounted for more than a quarter of the solar power developed so far in 2025. For the rest of the year, the Lone Star State plans for another 9.7 gigawatts of new solar capacity, or nearly half of all of U.S. solar planned for development over the time period. Texas' sunny weather, availability of large amounts of land and quickly-increasing power demand have drawn solar energy development.
