in this article bio-engineers have discovered a way to transmit messages from cell to cell. they took the bacterium M13, a bacteria that doesn't damage your body, but instead "sets up shop" inside you, it eats the food that you eat and it sends texts indiscriminately. the bacteria can send messages to other cells and due to its non-lethality bio-engineers took its key attributes and "reprogramed" it and therefore created what might be a "biological internet". with this new discovery, they were able to successfully transmit messages cell to cell. with more study on this subject biologists and bio-engineers could create multicellular communities to accompish important tasks. the M13 takes strands of DNA that bio-engineers can use those DNA strands and make what is basically a communication channel and it essentially creates an internet for cells. With this scientists can tell cells to stop growing, start growing, etc. and with this they can potentially stop cancerous cells and other diseases that include cellular mutations. the range of the M13 can be up to 40,000 base pairs and so far they have been able to transmit a message as far as 7 centimeters! cellularly speaking this range is very long. soon if this field is practiced scientists could make biosynthetic factories where they can make complicated fuels or large masses of microbes. Effectively, we’ve separated the message from the channel. We can now send any DNA message we want to specific cells within a complex microbial community,” said Ortiz, the first author of the study.
i think that with this research is going to be extreamely helpful in the medical field as well as to create new biofuels that are completely renuable . not only will it help in those areas but it can also help in making new and improved technologies for this . i think that this research is going to be worthwhile for the new medicines, fuels, and at this day and age it will be very helpful since it can offer people new jobs.
should this research be funded even though we know so little about it, or its consequences?
how worthwhile will it actually be since we are getting so close to stopping cancer and diseases related to it?
should scientists continue studying the M13 or try to find a potentially more efficiant bacteria?
Water pollution is a large set of adverse effects upon water bodies (lakes, rivers, oceans, groundwater) caused by human activities.
Although natural phenomena such as volcanoes, storms, earthquakes etc.also cause major changes in water quality and the ecological status of water, these are not deemed to be pollution.
Water pollution has many causes and characteristics.
Increases in nutrient loading may lead to eutrophication.
Organic wastes such as sewage and farm waste impose high oxygen demands on the receiving water leading to oxygen depletion with potentially severe impacts on the whole eco-system.
Industries discharge a variety of pollutants in their wastewater including heavy metals, organic toxins, oils, nutrients, and solids.
Discharges can also have thermal effects, especially those from power stations, and these too reduce the available oxygen.
Silt-bearing runoff from many activities including construction sites, forestry and farms can inhibit the penetration of sunlight through the water column restricting photosynthesis and causing blanketing of the lake or river bed which in turns damages the ecology.
My Summary.......
Water pollution can be found in lakes, rivers, oceans and groundwater. Volcanoes, storm, and earthquakes are not deemed to be or can be polluted.. Run off water can come form forestry and farms which may be polluted. Organic wates such as seeage and farm watse can have severe impacts on the eco system. Pollution is when grabage, sewage, or any trash is thrown or put into the water. This can also include metal, oil, food, and solids.
