Enzymes carry out fundamental biological processes such as photosynthesis nitrogen fixation and respiration with the help of clusters of metal atoms as active sites But scientists lack basic information about their function because the states ... - Read More
Photosynthesis is one of the most important processes in nature The complex method by which all green plants harvest sunlight and thereby produce the oxygen in our air is still not fully understood Researchers have ... - Read More
A world without plants would be a world without oxygen uninhabitable for us and for many creatures We know plants release oxygen by absorbing carbon dioxide and breaking down water using sunlight through the process ... - Read More
Scientific inquiry is a hit and miss proposition subject to constant checking and rechecking Recently a new class of materials was discovered called topological insulators nonmetallic materials with a metallic surface capable of conducting electrons ... - Read More
When we talk about global carbon fixation pumping carbon out of the atmosphere and fixing it into organic molecules by photosynthesis proper measurement is key to understanding this process By some estimates almost half of ... - Read More
Diatoms play an important role in water quality and in the global climate They generate about one fourth of the oxygen in Earth's atmosphere and perform around one quarter of the global CO2 assimilation i ... - Read More
About one fifth of Earth's atmosphere is oxygen pumped out by green plants as a result of photosynthesis and used by most living things on the planet to keep our metabolisms running But before the ... - Read More
Researchers from the University of Southern Denmark have synthesized crystalline materials that can bind and store oxygen in high concentrations The stored oxygen can be released again when and where it is needed We do ... - Read More
Researchers from the University of Southern Denmark have synthesized crystalline materials that can bind and store oxygen in high concentrations Just one spoon of the substance is enough to absorb all the oxygen in a ... - Read More
Geologists from Trinity College Dublin have rewritten the evolutionary history books by finding that oxygen producing life forms were present on Earth some 3 billion years ago a full 60 million years earlier than previously ... - Read More
By carefully controlling the position of an atomic scale diamond defect within a volume smaller than what some viruses would fill researchers have cleared a path toward better quantum computers and nanoscale sensors They describe ... - Read More
Spinach gave Popeye super strength but it also holds the promise of a different power for a group of scientists the ability to convert sunlight into a clean efficient alternative fuel Purdue University physicists are ... - Read More
Using ultra short X ray flashes an international team of researchers watched electrons jumping between the fragments of exploding molecules The study reveals up to what distance a charge transfer between the two molecular fragments ... - Read More
Biophysics researchers at the University of Michigan have used short pulses of light to peer into the mechanics of photosynthesis and illuminate the role that molecule vibrations play in the energy conversion process that powers ... - Read More
An international team led by Arizona State University scientists has published today in Nature a groundbreaking study that shows the first snapshots of photosynthesis in action as it splits water into protons electrons and oxygen ... - Read More
A crucial piece of the puzzle behind nature's ability to split the water molecule during photosynthesis that could help advance the development of artificial photosynthesis for clean green and renewable energy has been provided by ... - Read More
