Crispr-Cas9 system discovered in bacteria Tells us how smart they really are They fight the phages, their dire foes Cutting them up like weeding hoes Scientists found this so incredulous Thought they could use it to fight diseases Find the Crisprs in human genes Edit them and quell sickness scenes Locate the genes in DNA, Design the guide RNA Send it into the cell,  To ring the bell Cas9 executes the cut, Cell machinery prepares to shut Add, insert or delete, the work done is neat New protein from edited gene Makes disease a past scene Renewed health and humanity Crispr-Cas9 is extraordinary

Article: http://www.environmentportal.in/files/biomass.pdf plant organic matter or biomass transport fuel Like petrol (gasoline), an ideal biofuel should drop into today’s infrastructure and carry enough juice to get any vehicle where it’s going. Describing the disadvantages of ethanol is done well: a litre of ethanol takes a car only about 70% as far as a litre of petrol, and ethanol cannot provide enough power for heavy trucks or aircraft Description of how a hydrocarbon generates energy: he carbon–hydrogen bonds are where the useful energy is stored; breaking these bonds through combustion releases energy How scientific processes are explained easily: The water has to be boiled off, which means using more energy to produce the fuel. But butanol and water don’t mix, so they can be separated by less energy-intensive processes. Good summarization: “Electricity for the light vehicles, biomass for the heavies, and we’re energy independent in two decades,” he says. Liao,
