Tiny structures inspired by the shape of cactus spines allow a newly created material to gather drinkable water from the air both day and night, combining two water-harvesting technologies into one.
People might once have considered oxygen a human right. But the pandemic has revealed that access to oxygen—in a pure form, for medical use—is a luxury in most low and middle-income countries.
A wide variety of portable and wearable electronics have become a large part of our daily lives, so a group of Stanford University researchers wondered if these could be powered by harvesting electricity from the waste heat ...
In solar cells, about two third of the energy of sunlight is lost. Half of this loss is due to a process called 'hot carrier cooling' where high energy photons lose their excess energy in the form of heat before being converted ...
A team of researchers from the National University of Singapore (NUS) has recently developed a simple solution to address two of the world's biggest problems—water scarcity and food shortage. They created a solar-powered, ...
An evolutionary mystery that had eluded molecular biologists for decades may never have been solved if it weren't for the COVID-19 pandemic.
For generations, Brian Sackett's family has farmed potatoes that are made into chips found on grocery shelves in much of the eastern U.S.
A sustainable, powerful micro-supercapacitor may be on the horizon, thanks to an international collaboration of researchers from Penn State and the University of Electronic Science and Technology of China. Until now, the ...
Around the world, there are currently more than 18 billion internet-connected mobile devices. In the next 10 years, anticipated growth in the internet of Things (IoT) and in machine-type communication in general, will lead ...
In agriculture, there are many mechanical methods to indirectly measure a fruit's ripeness through its firmness. However, most fall short for soft fruits, which do not exhibit the same types of measurable vibration as harder ...
