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 […]

Sailing scientists discover almost 200,000 marine virus species: Data can help biologists understand how viruses affect the marine ecosystem
The oceans contain far more species of viruses than previously believed. While not all of them are harmful to humans, they may exert a considerable effect on the environment. Following an extended cruise around the world aboard a sailing ship, an international research team reported finding nearly 200,000 species of marine viruses. They released the details […]

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 […]

Is the aroma of coffee enough to boost cognitive focus?
What if you can get the brain-boosting benefits of coffee without the drawbacks of caffeine? Australian and Canadian researchers suggest that the placebo effect might apply to coffee. Many people start their day with a hot cup of coffee. Not only does it kick-start many brain processes, it also encourages strangers to strike up a […]

Researchers develop new coating to make lithium metal batteries last longer
When it comes to energy storage technology, researchers are either trying to perfect alternative types of batteries or tweaking the performance of lithium-ion batteries to the absolute limits. One of the latest efforts comes from a New York-based team, who has come up with a new way to extend the life of lithium cells while also ensuring […]

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 […]

One step closer to faster computers: Magnets blasted by lasers “act like oil and water in a jar”
Magnets rapidly recover their magnetic properties after taking a sharp hit that disrupts their magnetism. Researchers have learned more about this natural ability in an experiment where they fired lasers at slim magnets. The University of Colorado Boulder team examined what happened after a laser beam hit a magnet. They found that the magnetic spins of 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 […]

Mercury exposure catches up to world’s fastest bird; study says it can adversely affect breeding. What else is it harming?
The peregrine falcon (Falco peregrinus) may be the fastest bird on the planet, but it isn’t fast enough to outrun the toxic heavy metal named after the Roman god of communication and travel. The feathers of peregrines across the United States have displayed signs of mercury contamination. In Nevada, a researcher with the state’s Department […]
