(Natural News) European researchers have developed an improved diesel engine that’s more eco-friendly and efficient than current models, paving the way for greener and fuel-efficient vehicles. During a project meeting held in Austria, the researchers said that the new engine uses less fuel and emits 80 percent fewer contaminating particles than the current legal limits. Developing eco-friendly, efficient diesel engine The DiePeR […]

(Natural News) For a while now, scientists have been looking into the use of nanomaterials as a way to clean water. The idea is that nanofilters made from these materials would be able to remove even the smallest impurities and contaminants in water. In a recent study published in The Journal of Physical Chemistry, a team led by researchers […]

(Natural News) David Burns of the National Aeronautics and Space Administration (NASA) has proposed a new propulsion method that replaces conventional rocket engines with a “helical engine.” In a paper posted in NASA’s Technical Reports Server – a public database containing aerospace documents created or funded by NASA – Burns explained that the helical engine consists of a helix-shaped particle accelerator, an apparatus that […]

(Natural News) Researchers from the U.S. and China have developed a white paint that could keep surfaces up to 18 degrees cooler than the surrounding temperatures. In a study published in the journal Cell Reports Physical Science, the researchers said that the cooling paint absorbs almost no amount of solar energy and is better than similar products at […]

(Natural News) The dual-flush toilet wastes more water than it conserves, warned the U.K.’s largest water firm. In a recent report, conservation group Waterwise also estimated that between five to eight percent of U.K. toilets are leaking, with most of them being dual-flush. While designed to save water, the dual-flush toilet’s unique mechanism and its […]

(Natural News) A team of physicists from the University of Arkansas (U of A) has successfully developed graphene-based circuits capable of providing nearly limitless power for small devices. Described in a paper published in the journal Physical Review E, the findings prove a theory the physicists developed at the U of A three yeas ago. This theory stated that […]

(Natural News) Chinese researchers have developed a special kind of paper coating that allows invisible messages to be written on it with water. The messages are visible only under ultraviolet (UV) light and can be erased by heating the paper. In a paper published in the journal Matter, the researchers described how invisible messages can […]

(Natural News) Researchers from the University of Houston (UH) have unveiled a new air filter that could help fight the coronavirus pandemic. As detailed in an article published in the journal Materials Today Physics, the “catch and kill” device successfully killed 99.8 percent of aerosolized SARS-CoV-2 — the Wuhan coronavirus responsible for COVID-19 — in a single pass through […]

(Natural News) Aside from their fearsome array of spines, sea urchins have another evolutionary edge over other sea creatures: self-sharpening teeth. According to researchers from Northwestern University, the spiny invertebrates, unlike other animals whose teeth are built to resist constant wear and tear, have teeth engineered to chip and weather in such a way that they maintain […]

(Natural News) As parts of the country experience heat waves and power outages, scientists have been hard at work looking for new, more power-efficient methods to cool buildings. Recently, a group of engineers have designed one such system that absorbs indoor heat and shoots it up to outer space, all without using any electricity. The […]
