Plant cyborg able to move itself to a preferred light source

A team of researchers at the MIT Media Lab built a cyborg that combines a plant with electronics and ultimately allows the plant to choose when it would like to move to a brighter spot. The cyborg is the brainchild of team ...

NADINE: Power-plant-scale energy storage

On the way toward a CO2-neutral energy system, storage of large amounts of energy is still an unsolved problem. In the future, Karlsruhe Institute of Technology (KIT), the German Aerospace Center (DLR), and Stuttgart University ...

New system recovers fresh water from power plants

A new system devised by MIT engineers could provide a low-cost source of drinking water for parched cities around the world while also cutting power plant operating costs.

New plant tests energy-saving way to treat wastewater

Billions of years ago, when Earth's atmosphere reeked of unbreathable gases, microbes evolved in the absence of oxygen. As Earth matured and the nitrogen-oxygen atmosphere formed, these anaerobic, or oxygen-averse, bacteria ...

Plant

Plants are living organisms belonging to the kingdom Plantae. They include familiar organisms such as trees, herbs, bushes, grasses, vines, ferns, mosses, and green algae. About 350,000 species of plants, defined as seed plants, bryophytes, ferns and fern allies, are estimated to exist currently. As of 2004, some 287,655 species had been identified, of which 258,650 are flowering and 18,000 bryophytes. Green plants, sometimes called metaphytes or viridiplantae, obtain most of their energy from sunlight via a process called photosynthesis.
