Mixing graphene into concrete makes it two times as strong and four times as water-resistant, and also lowers its carbon emissions.
How can African countries best use their wind and solar resources to meet increasing electricity demand while minimizing investment costs and environmental impacts? Researchers say strategic siting and international energy-sharing are key.
We know that nature experiences can change environmental behavior—but it turns out those experiences don’t have to be real.
Inspired by geological rock formation, Swiss researchers have developed a way to manufacture ceramics that skips the heating altogether. Instead, they add water to the raw material and compress it at room temperature.
If we manipulate the antibiotic-munching tendencies of some bacteria, they could become our strongest weapon in the fight against antibiotic resistance.
The new microbead substitutes are made from a plant-based fiber called cellulose. Waste from agriculture or the paper industry could be a source of abundant cellulose to make microbeads, researchers propose.
Archaeologists think of artifacts buried underground as safely preserved. That might not be the case much longer.
Covering even part of the Sahara’s nine million square kilometers with solar panels and wind turbines could produce more than enough power for the entire world. It would also bring rain to the Sahara and make parts of it green.
It’s often not easy to live beside big predators. People have an instinctive and very understandable wariness of large, meating-eating wild animals, and they’re perceived through a lens tinted by centuries of fear and persecution. Yet we might accept these animals as neighbors, or at least appreciate when their ecological effects coincide with our own goals — such as preventing rabies in the Indian city of Mumbai.
Ya que cada vez más personas valoran las consideraciones éticas de lastimar a los animales al escoger sus dietas, el número de animales que mueren debido a la agricultura es una parte importante de información. Sin embargo, es sorprendentemente difícil de encontrar una cifra precisa.
