Along with genetics, fossils are one of the most useful windows we have into the natural history of life on Earth. Essentially, a fossil is a record of an organism, showing the size, shape and texture of different body parts.…
The fossilized remains of once-living organisms — animals, plants and humans — offer scientists a glimpse into the past. Fossils have long fascinated both paleontologists and enthusiasts for their ability to tell a story of a time long past. Most…
Like their much larger vertebrate cousins that feature so prominently in natural history museums everywhere, plants also can become fossilized and offer us a window into the past. Plant fossils are found in one of six broad categories. However, some…
Natural disasters can have a life-altering impact on the millions of individuals and families who are impacted each year. The effect of natural disasters is then also felt at the community, city and national levels. Natural disasters can have huge…
Large scale tree cutting can lead to deforestation, a transformation of an area from forest to terrain with little vegetation. As logging (the practice of cutting down trees) continues to increase – in order to fuel supplies of lumber, paper,…
Meteorologists use a wide variety of different instruments to measure weather conditions, but many of these weather instruments fall into relatively common, overarching categories. Thermometers, for instance, come in traditional liquid-in-glass forms and newer electronic forms, but both measure temperature…
Temperature in outer space depends on many factors: distance from a star or other cosmic event, whether a point in space is in direct light or shade and if it is subject to a solar flare or solar wind. Variation…
A single kilogram of uranium produces about 2 million times more energy than 1 kilogram of coal. Some may consider that a spectacular feat since you don’t have to heat uranium to make that happen; it heats itself through a…
Because windmills and solar panels operate using the wind and sun, those two energy sources are renewable — they will not run out. Oil and gas, on the other hand, are finite, nonrenewable and will not exist one day. You…
Currently, there are two ways to produce nuclear energy, through the use of fission and fusion. Fission reactions are more easily controlled than fusion reactions. This is why all modern nuclear power plants use fission reactions to produce energy and…
