The goal is to very, very gently slide the spatula down the side of the comb and then gently remove the larvae without rolling or squashing it. Then I had to gently place them into the prepared queen cell. Once I had repeated this 10 more times and placed the frame inside the hive the anticipation mounted, as there would be no way of knowing if any were undamaged.

We had to wait 8 days from the time we put them into the incubator till the queens emerged from their cells. My father and I were excited as this was my first attempt and his previous try had failed. Science has helped me and my father because beekeeping relies heavily on observation. This skill is useful as a lot can go wrong with bee hives including American foul brood, varroa and robbing.

This seafood that we know and love is becoming increasingly popular in our diet, but will it be the same for our grandkids — will it last? In , research began on the AquAdvantage Salmon which scientists claim can reach market size almost twice as quickly as normal salmon.

Something that salmon normally do not do. This means that they can be farmed year-round and in any climate. Resulting in a fish that reaches market size in just 18 months rather than three years for normal salmon. These are the offspring intended for our dinner plates on those warm summer evenings.

This AquAdvantage Salmon is the very first of its kind. Never before has a genetically modified animal been approved for human consumption. Many other GM animals have been developed and tested but politics and public fears have kept them off our dinner plates. The company that produces AquAdvantage Salmon believes in sustainable seafood production. They claim that their product is better for both consumers and the environment. The Salmon will be raised in land based farms, meaning that there is no risk of escaping salmon entering wild populations and no risk of diseases spreading out of containment.

All waste water is filtered extremely well and reused; the small amount that is not required is cleaned of all contaminants and used on nearby tomato farms as fertilizer. Also these AquAdvantage salmon are grown in land based systems close to the production factories. This eliminates the cost to transport them to the place where they cut them up.

This has created a salmon that is just as tasty as a wild one but costs a whole lot less to produce. By eliminating the need of wild salmon commercial fishing and introducing more land based farms, many threats to the wild salmon are removed.

Currently these threats include reduced food supply caused by over-exploitation of the salmon feed, parasites spread by water based fish farms and destructive fishing techniques. By introducing land based systems such as the one used by the AquAdvantage Salmon, the wild salmon will be protected from these threats and be allowed to live their lives largely uninterrupted. For years he has been promoting outright bans on GMOs, despite the fact that many scientists have declared them perfectly safe for all of you to consume.

He and other anti-GMO activists have been able to stall crucial experiments with GM crops that are designed to improve yields and nutrition, which would benefit poor people around the world. Ronald Stotish, chief executive of AquaBounty, also claims that the main advantage of the salmon is that the fish can be grown in tanks inland, greatly reducing the effects on the environment.

Now then, I know those of you that get out there and have been to South Westland Salmon Competition, you will know just how little fish are around. Even though I have had no luck recently, I thoroughly enjoy the feeling of a wild salmon fighting with your line. This is a feeling that I strongly want our future generations to experience. From my research, I think that it is an incredibly well thought out process that takes into account all the various viewpoints. I was especially impressed with its environmental impacts.

In order for one of the prime cattle beast from your local dairy farm to put on just 1 kg of body weight, it requires 8 kg of food. Whereas a GM salmon needs just 1kg of food to put on 1 kg of body weight.

This shows that the salmon is among the most economically sustainable protein source for humans. All of a sudden this GM salmon has become one of the few animals that puts on weight in equal proportions to its feed. However, currently the NZ ministry for the environment does not allow you and I to purchase and enjoy any fresh meat, fruit or veg that is a GM product.

I think that they should change their stance on this. If we can convince them to allow the sale of AquAdvantage Salmon here in our hometown, then we would be giving the wild populations of salmon in our local rivers a much better chance of surviving. All of these places will be able to host a larger population of salmon for your future generations to enjoy. If you are interested in finding out more please take time to look at the AquAdvantage Salmon home website Aquabounty. The enclosure is empty; the dinosaur has disappeared! Scientists are unable to control this creature, this monster — deadly but amazing.

This hunger to learn everything, to create something just because you can is what makes these characters so memorable. Scientists a term that covers a whole range of people and jobs have greatly contributed to making the world what it is today, and scientists who have a passion to help and learn about our world are the key to a future that we would like to come true.

Let the moa and the mammoth walk again? Or let a dinosaur once more paw the earth, or even make something new move and breathe? That power so often found in books or movies may soon not just be in our heads but in our hands. New Zealand is a land of paddocks full of sheep, cows and chickens. If we were to take a look at these creatures in the past, they would look quite different to the domesticated version we are so used to. Through intensive selective breeding, domesticated animals have been transformed so they better suit our needs; they can produce more meat and grow more quickly.

Breeding has also been used to reduce infection and avoid diseases. Living on a farm myself, I can easily see how our ideas and inventions influence the land and in turn influence our lives. This is one way we have used scientific methods in an attempt to create a world which can better support us.

Modifying animals for our own purposes can be a terrifying and controversial concept, but human nature seems to dictate that we will continue to pursue this.
