The results and responses by gender (male vs. female) are very real. In addition, astudyfrom 2011 further delineates that men have a higher cortisol level at baseline than women and that women do not emit the stress response as strong as men do—it’s fascinating, really. Of note, howe...
The non-profit organizationClimate Neutralhelps us to measure, reduce, and offset all the carbon we emit. And these offsets make us a carbon-neutral company. You can learn about theamazing carbon projects we support here, including tree planting, wind energy in China, renewable energy in Oklah...
Do humans emit electromagnetic radiation? How is ionizing radiation used? What are the different types of electromagnetic waves? How do photons carry electromagnetic force? Are brain waves electromagnetic waves? Why do electromagnetic waves not require a medium for travel? How are electromagnetic waves...
The type of energy they require to be energized The color of the visible light that they produce The length of time that they glow after being energized (known as the persistence of the phosphor) To make a glow-in-the-dark toy, what you want is a phosphor that is energized by normal ...
This south Vieques beach might not sound like much, but it's one of travelers' favorite experiences in Puerto Rico. During the day, Mosquito Bay is nothing special as Caribbean beaches go. At night, the waters emit a blue glow from organisms called dinoflagellates that live in the waters an...
So, gamma rays have the most energy (part of what makes them so dangerous to humans), and radio waves have the least. Of visible light, violet has the most energy and red the least. The whole range of frequencies and energies, shown in the accompanying figure, is known as the ...
Did not last long, this beautiful planet now the body becomes a hundred holes, that is what we humans do. We kept digging mineral resources, but also kept cutting trees and trees, which makes our planet into a crisis. The land now accounts for 29 percent of the worlds land, and seawate...
Which was discovered first: dark energy or dark matter? Why can't dark matter and dark energy be directly observed? Why do we call dark matter 'dark'? Does dark matter emit radiation? What is meant by "dark energy"? When was dark matter created?
As planets, they do not emit energy themselves but reflect radiation from their central star.1 The combination of the ensuing small luminosity and the apparent very close proximity to the star leads to a luminosity contrast between exoplanet and star that, as yet, makes a direct observation of...
Humans produce gases daily, sometimes to their embarrassment, but nowhere near the extent of these animals. On the next page, we'll learn more about the source of the methane problem and some of the controversy behind it. Why do cows and other ruminants produce methane? Methane ...
