Are Hydropower Dams the Future of Energy?

By Emily Folk @EmilySFolk Growing concerns about fossil fuels—especially their potential contributions to pollution and global warming—have individuals and governments around the globe looking for alternative sources of power. Hydropower is one of the oldest sources of electricity, already responsible for generating around 52 percent of the United States’ renewable electricity generation according to the National Hydropower Association. Hydroelectric dams are seen as some of the best options available. However, there are challenges that hydropower will need to overcome—otherwise, they may prevent the energy source’s widespread adoption. Current state of…

Emerging Battery Tech for Energy Industry

By Emily Folk, @EmilySFolk Advances in battery technology are transforming one of the most promising movements in the modern energy industry: the push toward renewable energy power solutions. Solar, wind, geothermal, and even hydro energy sources have a lot to offer besides near-limitless energy generation. They are clean in the sense that they have little to no impact on the surrounding environment, and they are generally inexpensive to produce under the right conditions. The problem with most renewable energy sources is that they tend to come with a glaring limitation.…

Bioelectronic “Nose” Sniffs Out Rotten Food

Does that food smell rotten? Researchers have developed a way to detect rotten food odors that are too faint for the human nose. By Emily Rhode One whiff of spoiled meat is usually enough to let us know that we should definitely not eat it. But what about those leftovers that have been in the refrigerator for a few days and still smell ok? We could throw them away out of an abundance of caution, but that becomes an expensive and wasteful practice. Or we could cross our fingers and…
