A third mechanism involves harmful molecules called reactive oxygen species (ROS). These molecules are natural byproducts of cell metabolism, but if too many accumulate, that can cause oxidative stress that damages DNA. Research has shown that heavy alcohol use increases levels of the enzyme CYP2...
When a person feels wronged and does not receive an apology, resentment can accumulate over time. This unresolved anger can lead to a toxic atmosphere in the relationship, making it difficult to interact positively. The offended party may start to withdraw emotionally, leading to a lack of tru...

While our immune system can detoxify and eliminate many of the toxins we are exposed to each day, it can only do so much. If we are exposed to more toxins thanour immune system can processand eliminate, these toxins accumulate in body tissues. As toxins accumulate in our bodies, cells an...
The atmosphere is an Earth-like air mixture of helium, oxygen and carbon dioxide. The two alien life forms that we envision for this world are animals -- mobile predators that live around the planet's few small bodies of surface water. Both aliens are short, about 1 foot (30 centimeters...
Hazard and risk assessment of nanomaterials (NMs) face challenges due to, among others, the numerous existing nanoforms, discordant data and conflicting results found in the literature, and specific challenges in the application of strategies such as gro
Our atmosphere is a massive fluid layer, and the right application of physics makes it possible for humans to traverse it. In this article, we'll walk through the basic principles of aviation and the various forces at work in any given flight. Contents How Do Planes Fly: Thrust and Drag...
there are hundreds of millions of these nanoplastics falling on your shoulders. There is so much of this in the atmosphere. There's been more quantifications of microplastics, which are again smaller than five millimeters, but when you get to the nanoscale below a millionth of a meter, it ...
