Thor's most renowned weapon is his hammer, Mjolnir, which was constructed in an astronomical manner, very literally. In the Marvel world, Thor's hammer was forged in the centre of a dying star. When a star dies in our universe, its core burns so hot that it creates a dense substance known as "neutronium." A single teaspoon of the substance, like Thor's hammer, is thought to weigh billions of tonnes. Some of the science in Marvel's Thor films is based on beliefs we know in this reality to make it more credible.
Even though the first cataract extraction operation was conducted in the 18th century, cataracts have really been treated for a much longer. In actuality, the earliest known cataract operation took place in the fifth century BC. As a result, it ranks among the earliest surgical techniques ever performed. The methods employed then were undoubtedly less advanced than those used now or even in the 18th century. When the lens was fully opaque and hard, a procedure called "couching" was applied.

Traditional cleaning goods like paper towels and throwaway clothing always wind up in landfills, and many of them aren't even biodegradable! As a result, it takes decades for them to decompose into soil. Microfiber cloths, on the other hand, are renewable. You use a cloth to clean your house, and then you just wash it. It will be as good as new after washing! Because microfiber cloth is extremely resilient, you may repeat this cycle for years without affecting its cleaning capabilities. My favourite microfiber cloth is almost ten years old and still looks brand new. It may have faded a little, but it still works perfectly.

Under all the ash and pumice that Mount Vesuvius' eruption left behind, many bodies were found. Italian architect Giuseppe Fiorelli discovered many of these had left holes in the ash layers after collapsing in 1863. He came up with the concept of injecting plaster into these holes to produce plaster casts of the Pompeii mummies. Since then, as they work to learn more about what transpired during this enormous tragedy, researchers and other architects have found this to be helpful.
According to Cleary, the KRAS gene, which causes about half of all human cancers, is mutated in more than 90% of cases of pancreatic cancer. However, a medication to turn off this specific gene has not yet been developed. One of oncology's "holy grails" is figuring out how to successfully target KRAS with a drug, according to Cleary. A Nobel Prize could be given to whoever develops an efficient KRAS targeted therapy because it is so crucial to oncology.
