Photosynthesis is a process used by plants and other autotrophic organisms to convert light energy, normally from the sun, into chemical energy that can be used to fuel the organisms' activities. Carbohydrates, such as sugars, are synthesized from carbon dioxide and water (hence the name photosynthesis, from the Greek ÏÏÏÎ¿- [photo-], "light," and ÏÏÎ½Î¸ÎµÏÎ¹Ï [synthesis], "putting together") during the process. Oxygen is also released, mostly as a waste product. Most plants, most algae, and cyanobacteria perform the process of photosynthesis, and are called photoautotrophs. Photosynthesis maintains atmospheric oxygen levels and supplies most of the energy necessary for all life on Earth, except for chemotrophs, which gain energy through oxidative chemical reactions.
Scientists at Cornell University may have stumbled across the cornucopia gene for crops, after scientific investigations revealed that a certain gene allows some plants to photosynthesize 50% more efficient than most common plants, including crops like wheat or rice. The researchers hope through genetic manipulation that they may transfer this gene to crops, allowing for [...]
Atom = at·om, noun \ˈa-təm\, from the greek ἄτομος (atomos) meaning “indivisible”. Apparently the atom isn’t that indivisible after all. Scientists at University of Bonn have managed to split an atom into two with a special laser, in special conditions, before merging it back together. Just like in the case of light, quantum mechanics allowed an atom to be split and then [...]

MIT researchers, guided by Andreas Mershin’s vision of a world fueled by cheap and renewable electricity, have recently published a paper in which they explain how photovoltaic panels made from plants can be [...]
If harnessed at a much greater potential than it is now, sunlight might not only become the primary source of energy on the planet, but the cheapest too. In one hour the sun sprays our planet with enough energy to power all the electrical needs of the word for an entire YEAR. Now that’s something [...]
The sun is the biggest source of energy on our planet, and it’s all natural. It’s enough to realize that in one hour the sun produces enough energy to power all the electrical needs of the word for an entire YEAR! Naturally, research has been underway for many years now for means of practically and [...]
As any fourth grader will tell you, photosynthesis is (in layman terms), the process through which plants (and bacteria, algae, etc) get the sugars and other organic compounds they need using energy from sunlight. However, during last week’s synthetic biology conference in Boston, a biologist from Harvard took things to a whole new level, presenting [...]
