    When Scientists Didn’t Exist

    Before the 17th century, science and scientists were not truly recognized. At first, people like the 17th century genius Isaac Newton were called natural philosophers, because there was no concept of the word "scientist" at the time.


    The Missing J


    The only letter that doesn't appear on the periodic table is J. Don't believe us? Check it out for yourself.

    Expanding Cubes

    An ice cube takes up about 9 percent more volume than the water used to make it.

    The Temperature of Lightning


    A lightning strike can reach a temperature of 30,000 C or 54,000 F. About 400 people are hit by lightning each year. Shocking!

    Rusty Mars


    On Mars, iron oxide forms a rust dust that floats in the atmosphere and creates a coating across much of the landscape.

    When Hot Water Freezes Over


    Hot water can freeze faster than cold water. However, it does not always happen, nor has science explained exactly why it can happen.

    Insects Sleep


    Insects clearly rest at times and are aroused only by strong stimuli—the heat of day, the darkness of night, or perhaps a sudden attack by a predator. This state of deep rest is called torpor and is the closest behavior to true sleep that bugs exhibit.

    Everyone's Your Relative


    Every human being has 99 percent of their DNA in common. A parent and child share 99.5 percent of the same DNA, and you have 98 percent of your DNA in common with a chimpanzee.

    What a Wingspan


    The Queen Alexandra’s Birdwing is the world’s largest butterfly, with a wingspan of up to 12 inches. It is found only in Papua New Guinea and is considered endangered.

    Einstein's Stolen Brain

    After Albert Einstein's death in 1955, pathologist Thomas Harvey at Princeton Hospital conducted an autopsy in which he removed Albert Einstein's brain. Rather than putting the brain back in the body, Harvey decided to keep it for study. Harvey did not have permission to keep Einstein's brain, but days later, he convinced Einstein's son that it would help science.

    Ears on Their Stomach?

    On each side of the first abdominal segment of a grasshopper, tucked under the wings, you'll find membranes that vibrate in response to sound waves. This simple eardrum, called a tympana, allows the grasshopper to hear the mating songs of members of their species.

    That's Sharp


    The human body is made of up of many strange components.
    Six elements account for 99 percent of the mass of the human body: oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus. The human body contains enough carbon for 9,000 pencils.

    We're Mostly Bacteria


    The human body has tons of bacteria.
    Scientists have estimated that about 95 percent of all the cells in the body are bacteria. The vast majority of these microbes can be found within the digestive tract.

    Deadly Water

    upload_2019-1-8_15-39-37.png Drinking TOO much water can be bad for you.

    It is possible to die from drinking too much water. Water intoxication and hyponatremia result when a dehydrated person drinks too much water without the accompanying electrolytes.

    Going Out With a Flash

    The sun will only get brighter from here.
    Over the next 5 billion years or so, the sun will grow steadily brighter as the hydrogen at its core gets used up, creating increased internal pressure and thus increased fuel conversion to helium. In 1.1 billion years, the planet could start to look like Venus. Eventually, the Sun will run out of hydrogen fuel and collapse.

    You can’t taste food without saliva

    In order for food to have taste, chemicals from the food must first dissolve in saliva. It’s only once they’ve been dissolved in a liquid that the chemicals can be detected by receptors on taste buds. During this process, some salivary constituents chemically interact with taste substances. For example, salivary buffers (e.g., bicarbonate ions) decrease the concentration of free hydrogen ions (sour taste), and there are some salivary proteins which may bind with bitter taste substances.
    Here’s a quick science experiment to test this out — get out a clean towel, and rub your tongue dry; then place some dry foods on your tongue, one by one, such as a cookie, pretzel, or some other dry food. After this session, drink a glass of water and repeat. Did you feel a difference?

    Octopuses have three hearts, nine brains, and blue blood

    Two of the hearts work exclusively to move blood beyond the animal’s gills, while the third keeps circulation flowing for the organs. When the octopus swims, the organ heart stops beating, which explains why these creatures prefer to crawl rather than swim (it exhausts them).
    An octopus also has nine brains — well, sort of. There’s one ‘main’ brain where all the analysis and decision making takes place and eight ancillary brains — one at the base of each arm — that function as preprocessors for all the information obtained by that arm. Two-thirds of an octopus’ neurons reside in its arms, which can independently figure out how to open a shellfish, for instance, while the main brain is busy doing something else.
    Our blood is red due to the fact that it contains iron-based hemoglobin to transport oxygen to cells. Octopuses, on the other hand, use the copper-based cyanoglobin, which performs the same function, albeit less efficiently — this makes octopuses have less stamina than you might expect.
    An individual blood cell takes about 60 seconds to make a complete circuit of the body

    You have about 5 liters of blood in your body (at least, most people do) and the average heart pumps about 70 mL of blood out with each beat. A healthy heart also beats around 70 times a minute. So, if you multiply the amount of blood that the heart can pump by the number of beats in a minute, you actually get about 4.9 liters of blood pumped per minute, which is almost your whole body’s worth of blood. In just a minute, the heart pumps the entire blood volume around your body.

    The known universe is made up of 50,000,000,000 galaxies.

    There are between 100,000,000,000 and 1,000,000,000,000 stars in a normal galaxy. In the Milky Way alone there might be as many 100 billion Earth-like planets. Still think we’re alone?
