1. During pregnancy, cells pass back and forth between a mother and her baby. What is truly amazing is that these baby's cells can stay active in the mother's body for decades after birth—a phenomenon known as fetal microchimerism.
If a mother’s heart, liver, or other organs suffer an injury later in life, these lingering fetal cells will actually migrate straight to the site of the damage. Once there, they can transform into the specific types of cells needed to help repair and heal her body.

2. A surprising number of life-saving and everyday inventions were born purely out of women looking out for others. In 1902, a woman named Mary Anderson was riding a streetcar during a freezing sleet storm in New York City. She noticed that the driver had to keep opening the front window to manually wipe away the ice, leaving him shivering and delaying the passengers.
Feeling bad for the freezing driver, she went home and sketched out a lever-operated rubber blade that could clear the window from inside the cabin. She patented the very first windshield wipers a year later, entirely because she wanted a stranger to stay warm and dry.

3. In the late 19th and early 20th centuries, a brilliant group of women known as the "Harvard Computers" completely revolutionized astronomy. At a time when women weren't allowed to operate the university's telescopes, they were hired to analyze thousands of photographic glass plates of the night sky by hand.
Despite being barred from the actual observatory equipment, their mathematical precision unlocked the universe. Annie Jump Cannon created the star classification system still used by scientists today, and Henrietta Swan Leavitt discovered how to measure distances in deep space—the exact "cosmic yardstick" Edwin Hubble later used to prove the universe is expanding.

4. Biologically, some women possess an actual superpower when it comes to perceiving the world. While the average person has three types of color-sensing cone cells in their eyes, a genetic variation allows some women to possess four distinct types of cones.
This condition, called tetrachromacy, allows them to see up to 100 million different colors—roughly 100 times more than the rest of us. Where a standard eye sees a basic green leaf or a gray concrete wall, a tetrachromat can perceive an incredibly rich, shifting gradient of entirely distinct shades and tones that most people simply cannot detect.

Women are amazing!
