Artificial Photosynthesis Can Produce Food in Complete Darkness

Artificial Photosynthesis Can Produce Food in Complete Darkness

Plants are growing in complete darkness in an acetate medium that replaces biological photosynthesis. Credit: Marcus Harland-Dunaway/UCR Artificial photosynthesis is being developed by researchers to help make food production more energy-efficient on Earth, and maybe one day on Mars. For millions of years, photosynthesis has evolved in plants  to turn water, carbon dioxide, and the …

Artificial photosynthesis can produce food without sunshine

Plants are growing in complete darkness in an acetate medium that replaces biological photosynthesis. Credit: Marcus Harland-Dunaway/UCR Photosynthesis has evolved in plants for millions of years to turn water, carbon dioxide, and the energy from sunlight into plant biomass and the foods we eat. This process, however, is very inefficient, with only about 1% of …

Transparency on demand: A novel process can render artificial materials transparent or even entirely invisible

Transparency on demand: A novel process can render artificial materials transparent or even entirely invisible

Induced transparency: The precise control of the energy flow (indicated by glowing particles in the fog) makes the artificial material become entirely transparent for the optical signal.

New artificial enzyme breaks down tough, woody lignin: Study shows promise for developing a new renewable energy source

New artificial enzyme breaks down tough, woody lignin: Study shows promise for developing a new renewable energy source

Woody lignin, seen here in purified form, holds significant promise as a renewable biofuel, if it can be efficiently broken down into useful form. Credit: Andrea Starr | Pacific Northwest National Laboratory A new artificial enzyme has shown it can chew through lignin, the tough polymer that helps woody plants hold their shape. Lignin also …

Artificial gravity: Definition, future tech and research

Artificial gravity: Definition, future tech and research

Artificial gravity is the creation of an inertial force in a spacecraft, in order to emulate the force of gravity. This concept is often seen in but is not limited to science-fiction shows like “Star Trek”, and researchers are currently working on methods to create artificial gravity in space.  Not only would the creation of …

Google’s DeepMind says it is close to achieving ‘human-level’ artificial intelligence

DeepMind, a British company owned by Google, may be on the verge of achieving human-level artificial intelligence (AI).  Nando de Freitas, a research scientist at DeepMind and machine learning professor at Oxford University, has said ‘the game is over’ in regards to solving the hardest challenges in the race to achieve artificial general intelligence (AGI).  AGI …
