AquaDust gel reveals water levels of plant leaves

If you want to know how much water a plant is taking up, one of the best places to look is in its leaves. A new material known as AquaDust could help scientists more easily do so, without harming the plant.Continue ReadingCategory: ScienceTags: Cornell… Continue reading AquaDust gel reveals water levels of plant leaves

Synthetic duck feathers could help ships glide through the water

The old saying “like water off a duck’s back” is well-earned – the water-loving birds have specialized feathers that keep them from getting too wet. Now, engineers at Virginia Tech have investigated the physics behind how they work and developed synthe… Continue reading Synthetic duck feathers could help ships glide through the water

Adaptable sponge soaks up phosphate from polluted waterways for reuse

The phosphate found in the Earth’s crust is a key ingredient for the growth of aquatic plants and animals, but human activity is washing far too much of it into our waterways. One consequence of this is the algae blooms that coat the surface of some la… Continue reading Adaptable sponge soaks up phosphate from polluted waterways for reuse

Surprisingly high mercury levels detected in Greenland glacier meltwater

The Greenland Ice Sheet is associated with a range of environmental issues, but now researchers have discovered a surprising new problem that hadn’t been considered before. Glacial meltwater was found to be unexpectedly high in mercury, which could hav… Continue reading Surprisingly high mercury levels detected in Greenland glacier meltwater

“Micro-tree” hybrid harvester purifies water and wrings it out of air

Water scarcity is one of humanity’s most pressing problems. Now engineers at Caltech have developed a new system that can tap into two different sources to produce fresh drinking water, by purifying dirty water during the day and collecting droplets fr… Continue reading “Micro-tree” hybrid harvester purifies water and wrings it out of air

Strange salty “crystal critters” help thwart fouling of metal surfaces

Pipes, instruments and surfaces that come into contact with salty water usually end up with a corrosive layer of salt and other dissolved minerals caked on, which needs to be scraped or washed off. Now, engineers at MIT have developed a new method for … Continue reading Strange salty “crystal critters” help thwart fouling of metal surfaces

Efficient solar desalination unit uses titanium-coated diaper material

Desalination is an important technology that may help expand the world’s supply of drinking water. Now, engineers in China have demonstrated a new, relatively simple design for a solar still with a high efficiency and low cost.Continue ReadingCategory:… Continue reading Efficient solar desalination unit uses titanium-coated diaper material

Self-contained SmartFarm grows plants using water drawn from the air

In many parts of the world there may not be much precipitation, but there is a fair amount of water vapor in the air – particularly at night. An experimental new device draws in that vapor, then uses it to irrigate edible plants.Continue ReadingCategor… Continue reading Self-contained SmartFarm grows plants using water drawn from the air

3D-printed graphene aerogel makes efficient, scalable water filter

Researchers at the University at Buffalo have developed a new method for 3D printing graphene aerogels that work well as water filters. The team says this technique helps make graphene aerogels scalable and stable enough to be used over and over.Contin… Continue reading 3D-printed graphene aerogel makes efficient, scalable water filter
