Archaeologists discover COCAINE and other psychotropics in the 1,000-year-old belongings of a South American shaman
Early shamans who lived a thousand years ago used cocaine and other mind-altering substances for their rituals, according to a recent study. In their report, researchers have uncovered evidence that suggests that Native American mystics took the drug, as well as several plant-based psychotropics, to alter their consciousness. This comes after a recent investigation of the dry rock shelters […]

Enhancing water harvesting efficiency: Researchers develop unique graphene foam that “harvests” water from air
Most water harvesting systems collect precipitation such as rain or water droplets from fog and other low-lying clouds. But a new device developed by Chinese researchers can get it directly from the atmosphere, provided there is sunlight. The new water collection system features nano-composite foam made from graphene. It relies on sunlight to power its processes, […]

Scientists use caffeine to give solar cells a unique energy boost
Caffeine helps boost the energy levels and mood of coffee drinkers. But did you know that it could also improve the performance of a new generation of solar panels? Researchers reported that coffee’s primary stimulant increased the efficiency of perovskite photovoltaic cells, an alternative approach to solar power. When bolstered by caffeine, perovskite solar panels […]

Electricity in unlikely places: Rock surfaces throughout the planet may act as natural solar panels
Rocks might not strike you as a potential source of clean and renewable energy, much less a substitute for solar panels. But Chinese researchers found that some stones sport metallic coats that naturally convert sunlight into electricity via the same process as photosynthetic organisms. The coating contains iron and manganese, two minerals used in photovoltaic […]

New polythene film can make cracked screens a thing of the past
Cracks and similar damage might occur less often in plastic materials that went through a newly developed manufacturing method. Developed by U.K. researchers, the process produces transparent polythene film with the durability of aluminum at a far lower weight. The plastics produced by this technique may one day see use in displays, glazing, visors, windscreens, and […]

Who needs stitches? Unique “slug glue” could be used to make better medical adhesives
The trail of slime left by slugs in the garden might eventually help patch up wounds. Researchers found that the “mucus” produced by a prevalent species of European slug possessed potential as a natural glue to close wounds, prevent infection, and reduce the risk of scars in humans. The slug species in question is the […]

Specks of gold: Understanding the benefits and risks of nanomaterials in cosmetics that use gold nanoparticles
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 molecules bound […]

Manufacturing breakthrough: Scientists can now weld glass and metal together
The manufacturing industry has recently welcomed what might prove a breakthrough technology. Scottish researchers showed off a new welding method that uses an incredibly fast laser to fuse together glass and metal. Glass and metal are two of the most common classes of materials used for various purposes. Due to their very different thermal properties, […]
