Every evening during the summer of 2020, Xingyi Zhou went up to the roof of her lab building at the University of Texas at Austin to check on two plastic boxes containing radish plants. Plants in one ...

Engineers find the hydrogel polyethylene glycol (PEG) doubles its water absorption as temperatures climb from 25 to 50 C, and could be useful for passive cooling or water harvesting in warm climates.

Students will plan and conduct an absorbency test on four different materials and be able to explain that when testing materials to learn about their properties, the materials need to be tested in the ...

Climate change, population growth, conflict and humanitarian crises are putting increasing pressure on the world's water resources. That is why Norwegian researchers are looking into whether ...

Plants may have no muscles, but they can grow upwards against the strain of gravity and their roots can even shift soil and rocks – because their cells can absorb water to form strong structures. Now ...

One of the biggest difficulties in helping people affected by natural disasters is transporting and providing them with essential resources like safe drinking water. Researchers at Australia's RMIT ...

Our atmosphere holds six times more water than you’ll find in all the rivers on Earth. The dew drops you see on grass and water droplets on a cold juice bottle are evidence of this natural reservoir ...

Scientists unveil a new crystalline material that reversibly changes color from yellow to red when absorbing water, paving the way for chemically sensitive detectors that can work without electricity.

Researchers developed an atmospheric water harvester so effective it was able to extract moisture from the air in Death Valley—one of the driest places on Earth. Reading time 5 minutes An ...

The vast majority of absorbent materials will lose their ability to retain water as temperatures rise. This is why our skin starts to sweat and why plants dry out in the heat. Even materials that are ...
