Carbon-14 dating works by comparing the ratio of carbon-12 to carbon-14 in a sample to that in a living organism, allowing for the determination of the age of formerly living things fairly precisely. The half-life of carbon-14 is 5,700 years, making it reliable for dating organic matter...
(2018) find that the correlation between intention and behavior averages 0.45–0.62, that is, the two are not perfectly aligned. This gap implies that the existing array of anti-food waste efforts carried out may only enhance consumers’ intention to reduce food waste but not be effective in...
These hardened facilities house command centers, ammunition depots and research labs that are either of strategic importance or vital to waging war. Because they are underground, they are hard to find and extremely difficult to strike. The U.S. military has developed several different weapons to ...
The alpha particles generated by the americium have the following property: They ionize the oxygen and nitrogen atoms of the air in the chamber. To "ionize" means to "knock an electron off of." When you knock an electron off of an atom, you end up with a free electron (with a negativ...
Urbanization and climate change are contributing to severe flooding globally, damaging infrastructure, disrupting economies, and undermining human well-being. Approaches to make cities more resilient to floods are emerging, notably with the design of flood-resilient structures, but relatively little is kno...

Interest in the connection between forests and human health is increasing among studies analyzing the effects of nature on human health [1,2,3]. The potential of forests as a source of health has led to numerous studies that provide evidence of the benefits of exposure to these forested ecosys...
However, in the late summer, grazing was the main factor shaping the community composition and transferring carbon to higher trophic levels. Identifying these small-scale interactions improves our understanding of the Arctic marine microbial food web and its dynamics. Keywords: microbial food web; ...
A driver might be found to have a level of 0.15, for example, while the legal limit is 0.08. To comprehend how we can gain access to such precise numbers, we have to ask ourselves: how does a breathalyzer work? What do those figures mean? And how do police officers find out if ...
