Monosodium glutamate (MSG) is a flavor enhancer in many foods and is safe to ingest. MSG is often associated with Chinese Restaurant Syndrome which describes a series of undesirable side effects like numbness at the back of the neck and a general sense of weakness. Eating to excess is more likely to cause these symptoms than consuming MSG.
Back in the day, sailors used the north star, Polaris, for navigation not because of its brightness but because it is the only star that does not appear to move over night. Polaris is not a single star, but is a triple-star system. None of these stars are even in the top 10 of the brightest stars in our night sky.
Contrary to popular belief, house flies do not have a life span of 24 hours. So, if you think it’s better to wait for your uninvited house mate to die instead of chasing it down, think again. The common house fly can live for up to a month!

One dog year is not equivalent to seven human years. Dogs age most quickly during the first two years and after that it greatly depends on the dog’s breed. For some dog breeds, one year is equivalent to a 14-year-old human.
Tequila and mezcal shouldn’t come with worm at the bottom. Only certain types of mezcals, another type of alcohol made from the agave plant, like tequila, contain the worm — and it’s actually an indication of low-quality alcohol or a marketing trick. The worm is a moth larva and its presence indicates infestation.
Gun silencers cannot muffle the sound of an exploding weapon to a whisper. While it does work to muffle the weapon, the result is about as loud as a police siren, which is still one hundred times less loud than the gun without a silencer.
Black holes are not actually the color black. They look black when we observe them because they emit no form of visible light. One of the only ways we know black holes exist is because of the gravitational pull they have on stars that otherwise appear to be orbiting empty space.
Although it is the closest planet to our sun, Mercury is not the hottest planet in the Solar System. With an average surface temperature of 864 degrees, Venus can melt lead and is the hottest planet in our Solar System.
There’s a common misconception that Albert Einstein was a terribly student in grad school and even failed mathematics. On the contrary, Einstein once said, “Before I was fifteen I had mastered differential and integral calculus.”
Contrary to countless sci-fi movie endings, there is no fire in outer space. Fire needs oxygen to exist, and there is no oxygen in space. Below is the ending of Star Trek III Destruction of the USS Enterprise.
Blondes and redheads are not “going extinct.” Genes do not go extinct. Recessive genes, like the gene for red or blonde hair color, can be carried from generation to generation without emerging as a hair color.
Car tires do not protect you from getting electrocuted if your car is struck by lightning. It’s actually your car’s metal frame that conducts the electricity straight to the ground.
Old tires rest near the abandoned Packard Automotive Plant December 13, 2013 in Detroit, Michigan.
Unless you’re one of the 1% of Americans who suffer from Celiac disease, gluten probably won’t have a negative effect on you. So go ahead and eat that bagel because studies show that you’re going to get bloating and gas regardless of your gluten-free diet.
Sunflower heads tend to face a certain direction and the myth is that they track the Sun as it moves across the sky throughout the day. Although sunflower heads are fixed, their buds do, indeed, track the sun before they bloom and the resulting direction the heads face is a result of this behavior.
Daddy longlegs spiders can, in fact, pierce human skin with their small mouths. But don’t worry, they also are not the most venomous spider in the world and the small amount of venom they carry will cause only a mild burning sensation for a few seconds and nothing more.
Macintosh computers are not immune to viruses. You can find a list of “The Ten Most Dangerous Mac Viruses” on securitywatch.pcmag.com. About 80% of the computer industry is ruled by Windows, so hackers are merely attacking the majority.
Many interrogators would like to believe that truth serum, like amytal sodium, inhibits their subject’s ability to lie, but that’s simply not the case. Truth serum creates a similar effect to being drunk, which might loosen your tongue but does not make you incapable of lying.
People don’t use “just 10%” of their brains. We use the entire brain for different processes at different times. We couldn’t survive if we scooped out 90% of it.
Don’t think that you can ingest countless amounts of Vitamin C and be alright. The upper limit for an adult is 2,000 milligrams a day. While a mega-dose of Vitamin C will not likely kill you, it will cause diarrhea, nausea, vomiting, headache, heartburn, and other unpleasant side effects.
Radiation is often associated with nuclear radiation, creating the misconception that all radiation is bad for you. Light is a form of radiation as well as microwave radiation that cooks your frozen dinners. There is a wide range for radiation and only the highest energy radiation is harmful to human tissue.
Seasons on Earth are the result of Earth’s axial tilt and not Earth’s distance from he Sun. If you think about it, Australian winter happens during North America’s summer and there is no way that could happen if seasons depended on our distance from the sun.
Alcohol does not kill brain cells, at least not immediately. Long-term problems with drinking to excess can lead to neurological damage, but if you just had one bad night, your brain will be fine in the morning even if your body might not.
