They use tools and can solve problems, and some, including the common raven (Corvus corax), can learn to talk better than certain parrots. One small Dutch company, called Crowded Cities, is using crows’ intelligence for the public good. The company has created an apparatus, the Crowbar, to train the birds […]

Companies are using drones to fight deforestation. One of them, BioCarbon Engineering, based in Oxford, England, aims to plant as many as 1 billion trees per year. It uses drones flying 300 feet over land to map an area’s level of deforestation, topography and soil quality, and report its potential for reforestation. With that information, automated planting drones carrying […]

Crystals made of proteins help cure cancer Crystals made of proteins are revolutionizing cancer research and treatment. They are not the usual crystals found in nature made of minerals but are man-made in a laboratory. They are tiny, clear and colorless, barely visible to the naked eye. As they are also very fragile, they break easily. So […]

Skin-to-skin Contact Helps Child Development The human touch, in this case skin-to-skin contact, sometimes called “kangaroo care”, is essential for healthy physical and psychological development.

And it’s the first project in the world to produce sewage-powered cars. Fukuoka sends the human sewage produced by its 1.55 million citizens to a sewage treatment plant, where biogas generated from […]

A hyperaccumulator is a plant that can grow in places containing very high levels of metals, absorbing them through their roots. They concentrate extremely high levels of metals in their tissues. […]
