The impact of spaceflight on the immune system has been investigated extensively during spaceflight missions and in model experiments conducted on Earth. Data suggest that the spaceflight environment may affect the development of acquired immunity, and immune responses. Herein we summarize and discuss the...
The gravity of the sun keeps Earth and every other planet in its orbit. If the sun weren't in a perpendicular position to the Earth, the Earth would travel in a straight line rather than an elliptical orbit. The fact that the earth orbits as it does creates life on Earth as we know ...
Planets orbit their parent stars while separated by enormous distances – in our solar system, planets are likegrains of sandin a region the size of a football field. The time that planets take to orbit their suns have no specific relationship to each other. But sometimes, their orbi...
Eventually, the plasma becomes so hot that the sun's gravity can no longer hold it down so it is hurled into space as the solar wind, dragging the sun's magnetic field along with it, according to NASA JPL. Did you know? The solar wind transports a million tons of matter into space...
That's why we need to look at Einstein's later theory, theGeneral Theory of Relativity, which describes how gravity affects the shape of space and flow of time. Imagine a stretched-out sheet. If you place a bowling ball in the middle of the sheet, the sheet will warp as the weight ...
Little to no gravity can affect how rooting materials function. Different rooting materials and soils are better than others when it comes to water and air distribution -- both key to successful plant growth. Out in space, grainy soils can cause water to scatter and fine soils can prevent air...
What does Gravity do when it comes to plant growth? How does plant growth effect the carbon-oxygen cycle? How do flowering plants grow? How is polarity important in embryonic development of plants? Does tropism affect plant growth? Why can dropping a magnet destroy its magnetism?
What Impacts Solar Panel Cost? Many factors affect the overall cost of a solar system. Below, we discuss these factors and detail how you can lower the cost of a system to maximize your lifetime utility bill savings. Your Location
What would the acceleration due to gravity be if you were in a space shuttle 250km above the earth? What effect did Copernicus' heliocentric (sun-centered) theory of the solar system have on humanity's perception of itself and its ...
After a long winter, the arrival of spring can be a welcome relief. The days grow longer, the temperatures increase, and the natural world around us comes to life again. But when the seasons change, our sleep patterns change with them. 经过漫长的冬天,春天的到来可以让人感到欣慰。 白天变长...
