(Natural News) A recent study has developed a novel device that harnesses temperature differences at night to generate electricity. Researchers from the University of California, Los Angeles and Stanford University teamed up to make an electricity generator that works during the cold, dark night. They came up with a thermoelectric device that was able to power an LED, […]

(Natural News) During a recent campaign stop in Wisconsin, presidential hopeful Joe Biden discussed some of his theories on race, including his belief that “a black man” invented the light bulb, not “a white guy named Edison.” Speaking to a group of black people, Biden talked about how he believes the best way to confront […]

(Natural News) Dengue is a mosquito-borne tropical disease that continues to be a pressing problem in some countries. Despite being painful and debilitating, it remains a neglected disease due to scant research, and there isn’t a range of treatments to choose from outside of bed rest and medication. In a major breakthrough, scientists from the University of […]

(Natural News) A Swedish-led research group succeeded in increasing the amount of electrical current that they can harvest from bacteria. The jump in efficiency is a big step toward the use of bacteria as sources of clean and renewable energy. In light of the dwindling supply of fossil fuels and the increasing demand for energy, researchers are exploring […]

(Natural News) Swedish researchers fiddled with wood until they managed to turn it technically transparent. They also made the biodegradable material capable of absorbing heat from sunlight and releasing it during colder periods. If used in the windows of buildings, the revolutionary material might help save energy by reducing the need for artificial heating and […]

(Natural News) Why do healthy baseball players die when a ball slams into their chest while patients survive potentially lethal tachyarrhythmia attacks when they get a timely thump to the chest? Swiss researchers hoped to answer this puzzle with a recently-developed instrument that simulates how a blow to the chest affects the heart rate. When the […]

(Natural News) The contamination of water, especially with fecal matter from animals or humans, is a serious problem. Pathogens from human or animal wastes can cause life-threatening diseases as well as economic losses. To address fecal pollution of water systems properly, it is important to know the origin of the waste. Human and animal wastes present different health […]

(Natural News) The waters of a U.K. harbor now serve as the hunting grounds of an aquatic drone called WasteShark. A robot shark with autonomous functions, the drone gobbles up plastic waste floating in the water, reducing the number of pollutants that enter the ocean while also protecting the local ecosystem and its inhabitants. Ilfracombe […]

(Natural News) In our oceans today, the most common form of debris you can find is plastic. While they come in different shapes and sizes, and the most widespread are microplastics – pieces of plastic which measure less than five millimeters. Plastic contamination is a growing environmental problem, especially in marine ecosystems, rivers, and lakes. Research teams […]

(Natural News) Chinese researchers debuted a new photocatalytic disinfectant for eliminating pathogenic microorganisms in water. Made from incredibly thin sheets of graphitic carbon nitride and powered by light instead of electricity, the new disinfectant offered an environment-friendly approach to water purification. In trials, it reportedly purified samples of heavily-contaminated water in just half an hour.  It also killed nearly […]
