Did You Know? | Kudos365 Curiosity Series 


1. Octopuses have three hearts.
Two hearts pump blood through the gills, while a third circulates it through the rest of the body. Their blood also uses a copper-containing protein called hemocyanin to transport oxygen, giving it a bluish appearance.

2. The Moon is slowly moving away from Earth.
Measurements made using reflectors left on the lunar surface show that the Moon is receding from Earth by about 3.8 centimeters—roughly 1.5 inches—per year. Over immense spans of time, this gradual change affects the Earth-Moon system and the length of Earth's day.

3. Bananas are berries, botanically speaking—but strawberries aren't.
Botanical definitions don't always match everyday language. A banana develops from a single flower with one ovary and meets the botanical requirements for a berry. A strawberry is an aggregate accessory fruit, with the small seedlike structures on its exterior actually being individual fruits.

4. The Pacific Ocean is wider than the Moon.
The Moon's diameter is about 2,159 miles (3,475 kilometers). The Pacific Ocean spans many thousands of miles at its widest extent. The comparison sounds surprising because we instinctively think of the Moon as enormous and an ocean as merely a feature on Earth's surface.

5. Some bamboo can grow nearly three feet in a single day.
Certain bamboo species are among the fastest-growing plants known. Under favorable conditions, documented growth rates can approach about 90 centimeters—roughly 35 inches—in 24 hours. Much of this remarkable growth comes from rapidly elongating sections of an already established plant.

6. The fingerprints of koalas can look remarkably similar to human fingerprints.
Koalas have ridged fingertips with loops, whorls, and other patterns that strongly resemble those found on human fingers. These similarities evolved independently, making them an interesting example of unrelated species developing comparable biological features.

7. The Sahara has not always been a vast desert.
Several thousand years ago, parts of today's Sahara contained grasslands, lakes, rivers, and abundant wildlife. Changes in Earth's orbital patterns altered African monsoon rainfall, helping transform this much greener landscape into the extremely arid environment familiar today.

8. The first known vending machine dates back nearly 2,000 years.
The ancient engineer Hero of Alexandria described a coin-operated device that dispensed a measured amount of holy water. Dropping a coin onto a small internal mechanism temporarily opened a valve. The principle—insert payment and automatically receive something—would be perfectly recognizable to a modern vending-machine user.

Sometimes the familiar world becomes much more interesting when we look a little closer: Explore. Discover. Learn.

Featured Biography | Gloria Steinem

Posted by Kronos Profile 09/16/26 at 01:00AM Biographies History See more by Kronos

Gloria Steinem  (March 25, 1934 – September 2, 2026) | Kudos 365 History Series

Journalist, Organizer, and Leader in the Modern Women’s Movement

Gloria Steinem was an American journalist, author, lecturer, and political organizer who became one of the most prominent voices of the modern women’s movement. Through investigative reporting, public advocacy, institution building, and decades of grassroots organizing, she helped bring questions of equality, reproductive freedom, political representation, workplace discrimination, and social justice into the center of American public life.

Steinem’s influence has never rested on a single organization or publication. She has worked across journalism, electoral politics, community activism, and international human-rights movements. Although frequently described as the public face of second-wave feminism, she has consistently emphasized that lasting social change is created collectively rather than by individual leaders.

NASA Astronomy Picture of the Day:

There was something behind the clouds. Upon close inspection, it was the Moon, which was hard to see yesterday around noon above the small village of Cessy, France. But soon, it was not only the Moon. As expected, a bright dot suddenly appeared from behind the Moon -- the planet Venus far in the distance. Captured in the single featured exposure, both appeared to show a crescent phase. The Moon's crescent was quite slight -- with only about 10 percent of its face illuminated by the Sun. In contrast, Venus's crescent was more full -- showing about 25 percent illumination. Venus appeared brighter because it is nearer the Sun and because its clouds are more reflective than the dark lunar surface. An occultation of Venus by the Moon is visible to only about 10 percent of the Earth, but in yesterday's event even most of that was experiencing daytime.

Why Are Manhole Covers Usually Round? || Kudos365 History Series | The Past That Shaped Us

How a simple piece of street infrastructure became an enduring example of practical design

We walk and drive over them every day without giving them much thought. They appear on streets from New York to Paris to Tokyo: heavy metal covers providing access to the networks hidden beneath our cities. And remarkably often, they are round.

The familiar circular manhole cover is such an ordinary object that its shape can seem inevitable. It isn't. Covers can be square, rectangular, triangular, or other shapes, and some are. But the circle offers a combination of practical advantages that made it particularly well suited to streets and underground utility systems. Its story is also part of a much larger transformation—the creation of the modern city beneath our feet.

NASA Astronomy Picture of the Day:

The hydrogen in your body and present in every molecule of water came from the Big Bang. There are no other appreciable sources of hydrogen in the universe. The carbon in your body was made by nuclear fusion in the interior of stars, as was the oxygen. Much of the iron in your body was made during supernovas of stars that occurred long ago and far away. The gold in your jewelry was likely made from neutron stars during collisions that may have been visible as short-duration gamma-ray bursts or gravitational wave events. Elements like phosphorus and copper are present in our bodies in only small amounts but are essential to the functioning of all known life. The featured periodic table is color coded to indicate humanity's best guess as to the nuclear origin of all known elements. The sites of nuclear creation of some elements, such as copper, are not really well known and are continuing topics of observational and computational research.
