Myth: Helicopters will drop like a rock when the engine shuts down. In fact, you have a better chance at surviving in a helicopter when the engine fails than you do in an airplane. Helicopters are designed specifically to allow pilots to have a reasonable chance of landing them safely in the case where the engine stops working during flight, […]

Today I found out what causes hiccups. In medical terms, a hiccup can be called a hiccough, a synchronous diaphragmatic flutter, or singlutus. Hiccups are classified into three categories: normal, protracted or persistent, and intractable. Protracted are those hiccups that last over 48 hours, but not more than one month. Intractable hiccups continue for more than one month. If hiccups […]

Today I found out how a smoke alarm works. At their core, smoke alarms are very simple devices that need only two functions: a way of detecting smoke and a way of alerting people to the problem. From new technology involving lasers to old world technology that relies on a lonely individual sitting in a tower on the side of […]

Today I found out there is a parody set of Nobel Prizes given out annually for trivial scientific achievements. These prizes (10 per year in a variety of categories) are called the IG Nobel Prizes (play on words: “Ignoble Prize”) and are given to those whose work “first makes people laugh, and then makes them think”. Essentially, they are given […]

Today I found out apple seeds contain cyanide. The seeds of apples, also known as “pips”, contain a sugar/cyanide compound called “amygdalin”, which turns into hydrogen cyanide when it is metabolized in your body. Hydrogen cyanide was one of the key ingredients to Zyklon B, the trade name of the pesticide used by the Nazis in their gas chambers. Other […]

Today I found out honey can be used for a variety of medicinal purposes. You may be skeptical about this because many such “natural” alternatives to medicine put forth are not backed by any scientific research. These types of claims are often based primarily on anecdotal evidence, which can be misleading. (I personally was extremely skeptical about honey’s medicinal value, […]

Today I found out if you eat an excessive amount of carrots, your skin will turn an orangish/yellow shade. Take notes those of you from New Jersey, you don’t need to get a fake tan to turn orange, you can simply eat large amounts of orange plants, such as orange carrots. The resulting condition is known as carotenemia and isn’t […]

Today I found out what causes limbs to “fall asleep”. Technically known as “paresthesia”, this syndrome is caused by the compression of specific nerves. When you sit cross-legged, sleep with your arm above your head, or position any limb in such a way to put excess pressure on a nerve, that nerve will stop sending impulses normally. Should the pressure […]

Today I found out how scars form. One of the main components of skin is a protein called collagen. Skin collagen is primarily made from specialized cells called fibroblasts. After scab formation, fibroblasts that are hanging out under the surface of the skin will begin leaking into the clot just under the scab. Once the clot is sufficiently soaked with […]

Today I found out navel orange trees are all perfect clones of one another and all originate from a single tree in Brazil. In 1820, a mutation occurred in a group of sweet orange trees growing on the grounds of a monastery in Bahia, Brazil. The mutation created a seedless orange that was much sweeter than the original citrus fruit. […]

Today I found out what causes headaches. There are approximately 200 different types of headaches, classified in two main groups: primary and secondary. There are in the neighborhood of 42 types of primary headaches and 157 secondary headaches (unless I lost count, but should you want to verify those numbers, or just need a sleep-aid, feel free to review the […]

Today I found out what causes a stroke. A stroke, known in the medical field as a cerebral vascular accident (CVA) or brain attack, is more or less a “heart attack” for the brain. Like any organ in the body, the brain needs blood to supply it with oxygen and nutrients. Should this blood flow become blocked by a clot […]

Today I found out gyroscopic effects have almost nothing to do with your ability to ride a bike. The problem with the forces generated from the gyroscopic effect on a typical bicycle is that they simply aren’t very powerful when considering the physics involved in having the majority of the center of mass of the bike at the top (with […]

Today I found out it is actually quite safe to fly through an asteroid field. The reality is that the asteroids in asteroid fields are incredibly far apart and most of the objects in these fields are very tiny. There are generally hundreds of thousands of miles between these objects and most of them are no bigger than a tennis […]

Today I found out what causes leprosy. Known as Hansen’s Disease, leprosy is caused by a type of bacteria (mycobacterium leprae) that multiplies very slowly. Its incubation period can last up to 20 years and it mainly affects the skin and peripheral nerves. Contrary to the social stigma, leprosy is not highly contagious, and does not cause body parts to […]

Today I found out the Earth is hottest when it is furthest from the Sun on its orbit, not when it is closest. During the period when the Earth is furthest from the sun (aphelion), the average temperature of the entire planet is about 4°F (2.3°C) higher than when it is closest to the sun (perihelion). On average, the intensity […]

Today I found out how Gecko’s feet stick to almost anything. It has been observed since the 4th century BC that geckos have the ability to climb walls, hang upside down, and apparently “stick” to anything. Aristotle was the first known to have commented on the phenomenon, stating gecko’s have the ability to “run up and down a tree in […]

Today I found out dog mouths are not cleaner than human mouths. If this were the case, I’m pretty sure a dog’s mouth would be some sort of medical miracle, considering: they rarely if ever have their teeth brushed or mouths cleaned; they literally put their mouth on everything; and they use their tongue as toilet paper for not only […]
