In simple terms, a hazard is a dangerous situation or event that carries a threat to humans. A disaster is an event that actually harms humans and disrupts the operations of society. Hazards will be considered…
It turns out that the almost endless arguments over the merits of a certain song or certain band might all stem from something physical. Different people really do sometimes hear the same sounds in entirely different ways. Even the smallest differences in our individual skull structure or bone density can change the way our brain receives and processes sound waves, changing the frequency that our bones vibrate at as we hear sounds. That can also impact our ability to understand and process language, and it’s been found that inner ear structures might also impact agility.
The definition of literature is a tricky one, and some argue that today, things like graphic novels, movies, musicals, and comic strips can even be considered literature if they move the right people. There are some hallmarks of what makes a work a classic, including reaching a wide audience, having a profound impact on the shaping of culture, standing the test of time, and capturing the heart and soul of the era being depicted.
Across most of Europe, witches were known for communing with the Devil and cursing their neighbors. Sicilian witches, though, were thought to commune with the fairy world. Most of the ills that were visited on mortals came from angry fairies, and Sicily’s fairy witches acted as go-betweens for the mortal and the fairy world, resolving disputes and curing illnesses.
When it comes to nutritional content and preparation, food comes in three different categories. Minimally processed foods—like fruits and veggies—have only minor things done to them such as washing, peeling, and removal of seeds or stems. Processed foods have undergone some process that changes their basic nutritional structure, like pasteurization. While that’s not necessarily a bad thing, numerous processed foods are combined into ultra-processed foods, and that’s when things can get dangerous. Not all vitamins and minerals were created equally, especially when it comes to products that claim to be things like “fortified.” Studies now show that we get about 60 percent of our energy from ultra-processed foods, and almost 90 percent of that comes from added sugar.
While we’re not sure why auroras have so many different shapes, we do know what causes the different colors. When the Sun’s particles interact with oxygen, the greenish-yellow lights occur. Nitrogen causes the red, blue, and purple lights, and height has something to do with it, too. The lowest lights are the blue ones, while red lights are the highest. And there’s a fascinating variety of myths associated with the lights, from the idea that they’re the spirits of the unborn to harbingers of tragedy or good fishing.
For skeptics, the idea of cryptozoology is paranormal bunk that has more to do with looking for mythical monsters than real science. In 2004, Chad Arment’s cryptozoology textbook outlined the four different types of cryptids that should be under investigation: animals outside their usual geographic range, individuals within a species that have some extraordinary characteristic, creatures that look like a species declared extinct, and creatures that are completely unlike anything accepted by science. This is an attempt to make cryptozoology a little more accepted in the scientific community and to get rid of the idea of other types of cryptids, like those whose existence is passed down in folklore and myth.
The Chimera was a creature from Greek mythology, having the body and head of a lion, a second goat’s head, and the tail of a snake. A chimera, however, can be any creature made up of the parts of different animals, and there are plenty of chimeras in world mythologies. Even Capricorn, today’s constellation and zodiac symbol, is technically a chimera with the body of a goat and the tail of a snake or fish.
The term “autism” refers to a series of disorders that are largely characterized by the amount of difficulty the person has with social and communication skills. Those diagnosed with Asperger’s syndrome are on the high-functioning end of the spectrum, often possessing a high intelligence along with their social difficulties. Childhood disintegrative disorder is characterized by a regression into autistic symptoms where there were none before, PDD-NOS is diagnosed when a child doesn’t meet the full criteria for autism but displays some characteristics, and Rett syndrome is a physically debilitating version of the disorder that strikes mostly girls.
