Photosynthesis
-
According to a new international study using NASA satellite data, sizable parts of the Earth have shown significant greening over the last 35 years largely due to rising levels of carbon dioxide in the atmosphere.
-
Researchers from Concordia University are looking to tap into what may be the most plentiful yet overlooked source of power in the world. The group has invented a power cell that harnesses the electricity created during the natural processes of photosynthesis and respiration in blue-green algae.
-
The ESA has officially selected the Fluorescence Explorer – or FLEX – as the eighth Earth Explorer satellite. The mission will study vegetation around the planet, gathering information about planet health at a time when a growing population is putting increased strain on food production.
-
Scientists have discovered a way to make great improvements in photochemical hydrogen production using two of the most abundant elements on earth – hermatite and silicon – and the power of the sun to achieve "unassisted" water splitting.
-
The world's first 3D-printed wearable containing living bacteria, designed to support the human wearer as a type of "living spacesuit" on trips to outer space, has been displayed at TED 2015.
-
This "bio-digital" structure sees fluid filled with microalgae organisms pumped around an otherwise transparent shelter to produce dynamic shade, energy in the form of biomass, and an impressive amount of oxygen, while responding to the presence of visitors to produce interesting visual effects.
-
Scientists have created a hybrid system of bacteria and semiconducting nanowires that take water, sunlight and carbon dioxide and turn them into the building blocks of biodegradable plastics, pharmaceutical drugs and even biofuel.
-
Researchers at the Australian National University are one step closer to creating an artificial photosynthesis system after replicating one of its crucial steps. The development may lead to an abundant source of hydrogen, a cheap and clean fuel that could replace all petroleum products.
-
Researchers at the Swiss Federal Laboratories for Materials Science and Technology (Empa) have developed a way to simulate photosynthesis using relatively low cost materials and a design based on the eye of a moth.
-
Researchers at Princeton University have converted CO2 into water and formic acid by using an electrochemical cell powered by a commercially available solar panel.
-
ScienceScientists have recently experimented with a combination of biological and photonic quantum mechanical states to form a new half-light half-matter particle called the “polariton.” It could help realize fully synthetic systems that replicate biological photosynthesis.
-
German researchers have created a bio-based solar cell capable of generating a continuous electrical current of several nanowatts per sq cm. The new approach, avoids damage to the tapped photosynthetic cells, an issue that has plagued previous attempts to harness nature's "power plant."
