The study of Biomimicry (or Biomimetics) looks at elements and systems of nature and attempts to replicate them to solve complex human problems. This is applied in fields from materials science to architecture. Some examples of biomimicry include: How the tiny hooks on bur fruits inspired Velcro. Leonardo da Vinci’s flying machine inspired by the structure of bat wings. Shark skin is being studied to (continued)

A neutron star is so dense that one teaspoon of its material would have a mass over 5,500,000,000 tonnes (5.5 billion), about 900 times the mass of the Great Pyramid of Giza (often cited as 5.9 million tons / 5.3 million tonnes). At the extraordinarily high densities of neutron stars, ordinary matter is squeezed to nuclear densities. All of that matter is packed into a radius on the order of 10 kilometers (6 miles).

The astronomical unit (or AU) is defined as approximately the mean distance between the Earth and the Sun. It is defined as 149,597,870,700 meters or approximately 93 million miles. At this distance, it takes slightly more than 8 minutes and 19 seconds for light to travel between the Sun and the Earth (or 1 AU). AU is one method of (continued...)

In the double-slit experiment, the wave nature of light causes the light waves passing through two slits to interfere, producing bright and dark bands on the screen – a result that would not be expected if light consisted of classical particles. However, the light is always found to be absorbed at the screen at discrete points, as individual particles (not waves).

Origin of life research is the study of how life came to be as a transition from non-life to life in the vastly different early Earth environment. What happened 4 billion years ago before LUCA? Abiogenesis is the scientific hypothesis for origin of life explaining a natural process by which life arises from non-living matter, such as simple organic compounds. Abiogenesis asks: how did pre-life chemical reactions give rise to life?

The adult human brain weighs on average about 1.2–1.4 kg (2.6–3.1 lb) which is about 2% of the total body weight. Although the human brain represents only 2% of the body weight, it receives 15% of the cardiac output from the heart, 20% of total body oxygen consumption, and 25% of total body glucose utilization.

400 million years ago, in the Devonian period, cartilaginous fishes such as primitive sharks became more numerous. The first tree dates to about 385 million years ago, and the Dinosaur Age started 252 million years ago, making sharks older than trees and dinosaurs.

Evidence is mounting that loggerhead turtles use a form of navigation termed Magnetoreception. This allows them to sense the Earth’s magnetic field. It has been observed that young loggerhead turtles inherit a magnetic map and magnetic compass sense that guides their first transoceanic migration. The turtles change their migration direction due to the magnetic fields in key ocean areas.

In the 17th century, Isaac Newton discovered that prisms could split up white light into a spectrum of colors. He also showed that the spectrum could be recombined to recreate white light. Newton was the first to use the word spectrum in describing his experiments. Today we call the band of the electromagnetic spectrum that is visible to the human eye the visible spectrum. Learn more:

The fastest-spinning neutron star known is PSR J1748−2446ad, rotating at a rate of 716 times per second or 42,960 revolutions per minute, it’s equator is spinning at approximately 24% of the speed of light, or over 70,000 km per second.
As the star got compressed into a much smaller and denser star its rotation speed increased, just like a figure skater, this is called the conservation of angular momentum.

Space is big, really really big. If you do the math, you will find that ~1.4 million Earth’s could fit in a line from the Sun to the Heliopause. It took 35 years for Voyager 1 to reach it.

Our Moon is drifting away from the Earth at ~ 3.8cm per year. Scientists know exactly how fast because of the Lunar Laser Ranging Experiment. This effect is due to tidal interactions. The ocean closer to the Moon actually bulges toward it. Because of the planetary rotation of the Earth and the gravitational interplay between the two, the Moon is pulled faster along its orbital path. This boost in speed slowly pushes the Moon into...

How much DNA do humans really share with bananas? It is often repeated that humans share 60% DNA with bananas, but what is the important nuance of this statistic that gets left out? Read here:

3,000-year-old honey found in Egyptian tombs is still edible. This is because honey contains about 80% sugars with close to no free water. It contains hydrogen peroxide released slowly by the glucose oxidase enzyme. It is also acidic, with a pH between 3.2 and 4.5 which is close to vinegar. This combination of factors makes honey hostile to microbial life.
