(andy mckemey, head of field operations, oxitec) "what we can do is look at the proportion of mosquitos we get back from the field and see what proportion have the gene, which means they aren't going to as opposed to the wild. and based on that ratio, we can adjust the release of our males". so far, that tracking shows promising results. one study done in the brazilian city of el dorado showed an 82% reduction in mosquito larvae.... compared to a non treated area 1.5 km away.. scientists warn the spread of zika could spiral into a global pandemic... who would have thought the key to stopping it... could be a glowing.. mutant mosquito.. erin mclaughlin, cnn oxford england > ((paul joncich)) the c-d-c says there are two possible vaccines for the virus.

perception going to be to somebody like that who is giving it away for free versus a company like oxitecrying to make a living. >> yes, we're talking about eradicatingaterrible class of diseases, but there is a genie out of the bottle with this gene drive. as soon as you make the decision to release these mosquitos into the environment, what's going to happen is going to happen. there's no going back >>> the public seems to be afraid of g.m. organisms because they don't know much about them >>> they have fascinating mitigation strategies to keep on top of how they're doing. they're starting in a remote place and see what happens there. when we have a better understanding of how these animals impact the environment we can take it elsewhere >> we have all seen jurassic park, all right? >>> they will naefr leave the island >> this mosquito has spread all over the world. it is piggy backing on humans, but still an island is a relatively safe place. these issues raise a tonne of questions which we here at techknow, we're going to stay on top of. that's it for this episode. see you next time.

but to understand what the oxitec mosquito is we're heading to the lab. >> micro-injection i'm guessing that's a very tiny needle. >> that's right. we can use that needle to peers the outside of the egg, the egg will still hatch. >> can i give it a shot? >> absolutely, please do. >> they make it look easy. it isn't. >> that's it. that's it. and keep pushing, the needle will pierce the egg. there you go. >> just like that i might have potentially genetically modified a mosquito. >> exactly. >> these mosquitos are receiving a gene that would inhibit production. offspring will not be able to reproduce so will die off before they can produce or pass on disease. john whether it's genetic modification or conventional pesticides, something has to be done and the key is controlling the population in the wild. >> what is the explosion with regard to the virus? >> a lot of experts are pointing the finger at el nino. it is hot out there, there are drought conditions and people are storing water in their backyard. they are opening up their windows to allow a cool breeze but it allows mosquitos to c

the good news is a company called oxitec has announced plans to release genetically modified mosquitoes in brazil that could help reduce the populations of mosquitos nevada health most common symptoms of the virus are fever, rash, joint pain and red eyes. there are no confirmed cases of the virus here nevada. republican donald trump kept not show up at the night. but somehow, he was still part of the discussion. fox news doug luzader has look at the highlights. ou really needed to split your screen to take this all in last night. most of the republican contenders on a debate stage in iowa while frontrunner donald trump boycotted it, appearing at the same time at an event for veterans just a few miles away. but, make no mistake. trump had a presence at the debate. cruz says "..let me say, i'm a maniac and everyone on this stage is stupid, fat, and ugly. and ben, you're a terrible surgeon. (laughter) now that we've gotten the donald trump portion out of the way." there is no question that the debate took on a different tone without trump. cruz -- number two in most iowa target. but, there
