Curious Droid presents 7 freakish genetically modified animals. Over the
past 30 years biotechnological developments have allowed scientists to
alter the genetic makeup of bacteria, plants, animals here are 7 of these of such
experiments but they represent just the tip of what will become a massive iceberg at
number seven we have the sudden death mosquitoes dengue fever is a
mosquito-borne virus that causes 2.3 million infections and over 25,000
deaths per year worldwide as yet there is no cure but to deal with this scientists
have created what are called sudden-death genetically modified
mosquitoes which are released into the wild and breed with the indigenous
mosquito population these then passed for special gene to their offspring this
special gene means that the baby mosquitoes die before they themselves
could breed thus reducing the number of mosquitoes that could go on to infect people
trials in specific areas have showed up to an 80% decrease in the mosquito
population up to three months after the initial release number six
glow-in-the-dark cats the glow in the dark cat was developed as a way to fight
the feline immunodeficiency virus or FIV which is related to the human version of
HIV and typically affects feral cats in 2011 American and Japanese scientists
inserting genes into cats to help them resist FIV in order to mark the cells
more easily they also inserted a green fluorescent protein into both genes
transferred to the feline eggs this protein which is naturally produced in jellyfish
is commonly used in this area of research to monitor the activity of altered genes this
let the scientists examine how to resistant gene develop within the cats
by examination under a microscope the modify cats are always normal during the
daytime but sometimes they glow at night
number five the web spinning spider goats when it comes to natural goods
flexible and strong spider silk is incredibly valuable spider silk is pound
for pound five times stronger than steel and far more elastic than rubber
normally getting enough spider silk for these applications requires a large
number spiders however spiders tend to be territorial so when the researchers
set up spider farms the spiders killed each other so they inserted the silk
making genes into the mammary gland cells of goats the cells then make the
extra protein to make the spider silk the milk can then be collected and the
protein is extracted and spun to make a spider silk Thread. number 4 singing mice
sometimes there is no defined end result for the genetic tweaking involved and
this is what happens with the japanese evolved Mouse project it's a bit like
adding some extra genes and let's see what happens when the results of
experiments are allowed to breed one morning while checking on a new litter
of mice researchers discovered that one of the baby mice was singing like a birds
they focused on that mouse and now bread over a hundred mice that can sing but it
doesn't end there
they noticed that when normal un-modified mice grew up around the singing mice
they too began to use different sounds and tones like a simple language the
project's goal is to artificially speed-up evolution but we might have
just created a super talking mouse that will one day go on to take over the
world and experiment on humans in the future
number three popeye pigs for all you meat eaters out there but love bacon and
hate vegetables Japanese scientists have taken pigs and added gene from spinach
should create healthy and meet with a lower saturated fat content and contains
proteins are found in the spinach leafs
dubbed the Popeye pigs because of the spinach these pigs have been inserted
with special Spanish gene that converts for saturated fat into unsaturated fat
although pigs have been cleared of any health complications their announcement
was met with a public outcry maybe a better solution is just to eat more
greens with your organic pork instead of trying to create pigs that do both
number two cows that produce human milk babies could be fed on human milk
produced by cows in the wake of the latest genetic modifications scientists
have created cattle that have been given human genes to make their milk contain
the same nutrients and fat content as breast milk however human milk differs
from cow's milk in several important ways it contains high quantities of
nutrients beneficial to the baby's growth and also special immune system
antibodies that are specific to that mother and baby which could never be
replicated using this method number one glowing zebra fish Glowfish is a
patented brand of genetically modified fluorescence zebrafish with bright red
green and orange fluorescent colors though it was originally created to show
the presence of toxins in water it was the first genetically modified animal
that has gone on to be widely available to the public as a pet in 1999
scientists at the National University of Singapore who work in the gene called
the green fluorescent protein GFP originally extracted from a jellyfish
but naturally produced a bright green bioluminescence they inserted the genome
into the zebrafish embryo allowing it
integrate with the zebrafish genome this course the fish to be brightly
fluorescent under both natural white light and auto ultraviolet light the
idea was to develop a fish that would detect pollution by glowing in the
presence of environmental toxins
