(Natural News) A recently developed “acoustic telescope” uses light-manipulating techniques to transmit and pick up sounds over long distances. Acoustic metamaterials make it possible for the device to target people at a distance and project sounds into their heads. Academics from the University of Sussex and their colleagues at the University of Bristol demonstrated how they […]

(Natural News) Single-use plastics cause plastic pollution, a problem that affects rivers, lakes, and oceans. To address this concern, researchers from the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) developed a recycling process that turns various materials made of polyethylene terephthalate (PET) into other useful products that will last longer. NREL’s research was published in the journal Joule. […]

(Natural News) Solid-state battery technology has reached a new milestone in terms of energy storage. Thanks to the new conducting material developed by Japanese researchers, all-solid-state batteries will boast the greatest energy density yet. The hydride lithium superionic conductor arranges clusters of hydrogen anions (negative ions) into specialized structures. The material displays far greater stability against lithium […]

(Natural News) Texan researchers recently presented a new type of moisture harvester that ran entirely on solar power. Their eco-friendly device passively gathered water vapor from the air and purified it into potable water. Many people still lack access to a reliable supply of clean water. The solar-powered moisture harvester may provide a solution to […]

(Natural News) Many cooking shows often feature intricately designed cakes that require incredible balancing and architectural skills. But the chefs who make these gravity-defying cakes need ingredients that will help the baked goods maintain their unique structures. The findings from a one-of-a-kind study might have the answer to their problems: a natural soy-based adhesive. Researchers from Purdue University […]

(Natural News) Even as internet of things devices grow ever smaller, they continue to require more power. But most of these smart devices are too small to fit batteries and power cords might restrict them. This led Japanese researchers to refine an existing tool which could collect electromechanical energy from its surroundings. Their new energy harvester is called a micro-electronic mechanical […]

(Natural News) Transistor technology got a much-needed speed upgrade thanks to Australian researchers. Their experimental nano-sized computer chip doesn’t have any silicon in it. Instead, the space normally occupied by semiconductor material is left open to air. Electrons that go through those air gaps move much faster than they do through silicon. They can reach velocities that are […]

(Natural News) Organic light-emitting diodes (OLEDs) are going to be much more energy efficient from now on. Korean researchers say they have found a way to improve the external quantum efficiency of an OLED unit. As their name implies, OLEDs are light-emitting diodes that use organic materials to generate light. This makes them more eco-friendly while […]

(Natural News) Researchers are banking on a newly-developed material to realize the long-standing dream of practical nuclear fusion. They believe high-temperature superconductors (HTS) can raise the efficiency of a fusion power plant to a level that is commercially viable. As their name implies, superconductors are extremely efficient conductors of electricity. They are used in the […]

(Natural News) How do you when your food has gone bad? Smell and taste are usually the best indicators, but even these can fail sometimes. That’s why companies like Braskem are working towards creating packaging that does the job for us. The thermoplastic resin producer has collaborated with Clemson University and Rio Grande do Sul […]
