Oregon wastewater facility makes its own power with human waste
Two weeks ago, we wrote a piece on upcycling your “business,” going into the green uses some companies found for human waste. Innovation and recycling mean looking everywhere possible for solutions, and The Optimist Daily loves writing about the ones that are found… even if they come out of Read More...
How to help the ocean from anywhere
We all have one big thing in common these days: the changing climate. We are all united by this because it will affect all of us, be it in the form of winter storms, drought, or sea-level rise. The good news is that we can all affect the climate too, in a positive way. Even living in the Midwest, Read More...
This is how we could clean our solar panels without water
The water footprint of solar power may rarely come to mind. It should because cleaning the dust off of photovoltaic panels requires hundreds of millions of gallons of water per year. In a bid to come up with a solution, MIT scientists have recently invented an alternative cleaning system that Read More...
Floating ants may inspire the future of robotics and adaptive materials
Ants are extremely adaptable creatures. The little critters are one of the strongest animals in relation to their size, being able to carry 50 times their own body weight. They are also the longest living insect, with some species living for around 30 years. However, the teamwork these tiny animals Read More...
Make the most out of your breakfast and your day
While it’s impossible to say what the most important meal of the day really is, there is one good reason why breakfast is so essential: when you start the day with a healthy, balanced breakfast, you nourish your body with the energy you need to get through the day. To get the full benefits of Read More...
What tiny water samples teach us about huge creatures
Environmental DNA (eDNA) has been a recent gold mine in research. We recently reported on how eDNA was captured from the air in a world first and how scientists were able to use this technique to distinguish zoo animals from it. This incredible tool can help ecologists study animal behavior and Read More...
Four ways to clean your house plants
Cleaning your plants may seem trivial, but there is scientific support behind keeping your leafy friends squeaky clean. The stomata and chlorophyll of plants, which absorb carbon dioxide and help perform photosynthesis, can be clogged and blocked by dirt and dust. Cleaning your plants helps ensure Read More...
Even in deserts, this system can generate water and electricity
The extreme heat of the world’s deserts makes maintaining a water supply and a steady supply of electricity difficult. At The Optimist Daily, we’ve written about optimizing solar panels with agricultural systems before. However, this experimental hybrid system from King Abdullah University of Read More...
Submarine to explore the underside of Greenland’s glaciers in a first
Scientists are desperately trying to save the world’s glaciers. As they hold a large amount of water and carbon dioxide, it is essential that we slow the demise of these structures for the climate's sake. We’ve previously written about a group using special mountain blankets on Mount Titlis Read More...
Levitating ice leads to deeper understanding of energy
Believe it or not, scientists have been levitating water since the 18th century. The Leidenfrost effect was first described in 1751 by a German doctor and theologian, who named the phenomenon after himself. Using a high temperature plate of 150˚C, he observed that a water droplet could be made to Read More...
