Astronomers have found the smallest planet yet outside our solar system, a rocky planet about one and a half times the size of Earth. Discovered by NASA’s Kepler mission, Kepler-10b is denser than Earth, with 4.6 times its volume. This gives it much the same density as an iron dumbell, says NASA. It was detected by mea...
On this day in 1969, the U.S. launched Apollo 8, the second manned spaceflight mission in the Apollo space program and the first crewed launch of the Saturn V rocket.

Norman Borlaug received a Ph.D. in plant pathology and genetics from the U. of Minnesota. He was acutely aware of starvation in the world due to food shortages. Norman worked for more than a decade cross-breeding wheat to grow quickly, be disease resistant, and have shorter, thicker stems. During these years, he and hi...
I saw a social media discussion in which former teachers shared their reasons for leaving the teaching profession. One teacher mentioned that having to create lesson plans and differentiate for each of her 20 students was too much work and too high of an expectation, given the resources available to her. How can anyone...

How does DNA code for proteins? This is probably one of the most complex processes and rather difficult to explain in a short space. These are the steps: The DNA remains in the cell nucleus but the production of the protein occurs in the cytoplasm. This requires the help of mRNA. DNA has the code for a protein which mR...
NASA’s Kepler Telescope has discovered 1,284 new exoplanets gravitating around distant stars. This is the largest amount of planets ever discovered at one time, and doubles the amount astrologists have confirmed up until now. “Before the Kepler space telescope launched, we did not know whether exoplanets were rare or c...
The Egyptian’s inventions were many and it might be easier to list the things they did not invent such as the wheel; not unexpected in a country where everyone travels on water. Most scholars now believe that isolated civilizations first arose independently at several locations; initially in Mesopotamia around Tigris a...
Frogs don't have external ears, but they do have ear holes, located directly behind their eyes. Frog ear holes are covered with thin tympanic membranes, or eardrums, that protect the inner ear cavity and help transmit sound vibrations. Male frogs' eardrums are larger than their eyes; females' are smaller. Good hearing ...

Nuclear bombs are weapons of mass destruction. They harness the forces that hold the nucleus of an atom together by using the energy released when the particles of the nucleus (neutrons and protons) are either split or merged. The effects of nuclear weapons would be catastrophic. to all life. That’s why CND campaigns a...
When most people think of coral reefs, they think of sunlit shallow shelves, teeming with sea creatures and iridescent tropical fish that almost anyone with a snorkel and a swimsuit can see. But much deeper in the ocean, 100 feet down and below, exists another type of coral reef. These deepwater reefs, many of which ar...
