Blue-Green Algae Runs Computer for Six Months

Image: A container holding blue-green algae that powered a computer A computer has been powered for six months by blue-green algae contained in a tiny container. In the near future, similar photosynthetic energy producers might be utilized to power a variety of tiny gadgets without the usage of scarce and unsustainable materials like those used in batteries. Christopher Howe and his colleagues at the University of Cambridge made a tiny enclosure out of aluminum and translucent acrylic approximately the size of an AA battery. They put a colony of Synechocystis sp. PCC 6803 cyanobacteria – sometimes known as "blue-green algae" – inside, which create oxygen through photosynthesis when exposed to sunlight . During the shutdowns during Covid-19 pandemic in  2021, the device was put on a windowsill at the residence of team member Paolo Bombelli and stayed there from February to August. It ran an Arm microprocessor with a constant current between its anode and cathode. The compu

Serbian Scientist Build Bioreactor in Urban Settings. It Is a Liquid Tree.

Planting trees is the most common approach for companies and governments to deal with climate change. However, the method is only appropriate for forests or large abandoned areas. We cannot plant a large number of trees in dense cities where the pollution is concentrated. Fortunately, Serbian scientists have developed a liquid tree to produce clean oxygen. The Big Problem According to the IHME (Institute for Health Metrics and Evaluation) reports, pollution is the major cause of human death, three times more than any disease such as HIV AIDS, malaria and tuberculosis. In the context of Serbia, the region has two coal power plants that contribute heavily to the destruction of its environment. As the city is densely populated, traffic and heating and cooling of buildings are also the pollution-causing factors. Therefore, creating green areas in the city is a complex target to achieve due to the lack of free space. The Solution- Making of The Liquid Tree/ LIQUID 3 Dr Ivan Spasojevic , a

Does lack of plants mean End of Photosynthesis on Earth?

Photosynthesis is a process used by plants and a few other organisms to make their own food by harnessing the energy from the sun’s light and converting it to chemical energy. The process of photosynthesis is dependent on a lot of factors and a change in any of these could actually prevent it from occurring normally, as we would like it. Major factors which could stop the process of photosynthesis include- absence of sunlight, carbon dioxide or water, since these are basic requirements for the process. While you might be aware that the process occurs in a small organelle inside the plant ’s cells known as chloroplast, chlorophyll is an important pigment for the process. Any loss of this pigment due to genetic or biochemical factors would also prevent photosynthesis. Also, the end result is photosynthesis is the production of glucose . So, if a plant has enough glucose, there will be a halt in the process. Biochemstry of Photosynthesis.  Image Source:
