(Natural News) Can light restore vision to blind people and help treat paralysis in patients with Parkinson’s disease? German researchers have recently examined the possibility of stimulating light-sensitive proteins to achieve therapeutic effects on various health conditions. Optogenetics is a technique that manages processes in the brain through light-based stimulation. It achieves its effects through […]

(Natural News) The spent shells of chicken eggs might go from unwanted biowaste to a cheap, renewable, and valuable alternative material to metals in lithium-ion batteries. A German-led study reports that powdered chicken eggshells successfully store large amounts of electrical energy. Led by researchers from Karlsruhe Institute of Technology (KIT), the international team tested eggshells […]

(Natural News) When your dog looks up at you with its mouth open wide and its lips pulled up at the corners, is it really smiling at you? Despite humans having over 30,000 years of history with dogs, the answer is still unclear. But researchers believe they are getting close to finding the answer. A group of neuroscientists from […]

(Natural News) The world’s very first electric-powered airliner is currently in development. The futuristic jet would emit zero greenhouse gas emissions directly. Instead of burning up fuel, the jet would convert the chemical energy stored inside liquid hydrogen cells into electric power. The electric power generated by the liquid hydrogen would be depended upon to […]

(Natural News) Are we living in a simulation? According to Massachusetts Institute of Technology (MIT) professor and computer scientist Rizwan Virk, it’s very likely. Virk’s ideas develop upon those first theorized by Oxford philosopher Nick Bostrom known as the simulation hypothesis. In this, he outlines three possibilities: That humanity, like many other human-like civilizations before it, […]

(Natural News) Additive manufacturing systems have come one step closer to printing out whole, working organs for emergency medical transplants. Researchers reported 3D printing a complete system of blood vessels found on a major organ. Every day, around 20 patients who desperately need an organ transplant die before ever getting one. There are not enough […]

(Natural News) You’ve heard of all the ways to convert light or wind or heat into usable electricity. But have you ever thought that the coldness of the universe might serve as an alternative source of clean and renewable power? Most energy production systems get their power from somewhere. Solar panels collect light while wind […]

(Natural News) Experts know that a strange species of bacteria found in oxygen-deprived sediment and soil can generate electricity. But they only recently learned that the microorganism achieves this through a method that differs from that used by other electric bacteria. Called Geobacter sulfurreducens, the anaerobic bacteria possess a unique biological structure. This previously unidentified feature makes […]

(Natural News) Need a cheap yet reliable way of purifying water without resorting to dangerous chemicals? Russian researchers have discovered the potential of graphene as a material for making water safe to drink. In their experiment, graphene treated water by trapping bacterial cells. The nano-material assembled into flakes that were easy to remove from the […]

(Natural News) Are gold nanoparticles safe for human use and consumption? European researchers have recently evaluated the benefits and risks of using nanomaterials in cosmetics, pharmaceutical drugs, and other products. Many sectors use tiny particles to create new materials and technologies. Their small size gives the nanomaterials many advantages. Changing the size, shape, and the […]
