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 bewildered by “mysterious crystals” found in the core of giant alien planets
Strange crystals might form in the incredibly hot and pressurized cores of exoplanets in other star systems. Researchers think that these mysterious mineral formations may determine the environmental conditions on the surface of the planet, including the ability to support life. The planets of our solar system fall into one of two groups: They are […]

Super-sized space bubbles in another galaxy are spewing cosmic rays in our direction
You have probably seen a child huffing and puffing and blowing at a bubble blower toy to fill the air with glistening soap bubbles. Researchers identified a galaxy in the universe that is going through a similar phase in its life — except its space bubbles are shooting cosmic rays in the general direction of […]

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 […]

Preppers, take note: Graphene could be a low-cost water purifier
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 purified water. […]

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 […]

Interstellar space travel: Another meteor from a distant star discovered by scientists, hit Earth in 2014 before ‘Oumuamua
‘Oumuamua is the first interstellar object discovered by man. But Harvard researchers have claimed that a smaller space rock from another star system arrived in the solar system years earlier – only to burn up inside the Earth’s atmosphere. Their findings suggested that such interstellar meteoroids may be numerous. Furthermore, alien life may hitch a […]

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 […]

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 […]
