GM – Genetically Modified food – Are we being Luddites? Is it time for us to embrace GM or are there too many uncertainties?

GM cropcircle1504_468x348 GM03biotech_ready GM-crops-c-001 GM 70467456_goldenrice

The question is whether it is the right time to embrace Genetically modified crops and animals and solve all the world’s food problems or are there too many unknowns?

On one hand there are always people who will oppose new ideas on the basis of ‘fear of change’.

On the other hand we have a long history of big corporations (and governments) lying to us so that we don’t know the true story (Nuclear energy and waste disposal is a good example – they even covered up the meltdown in Windscale for fear of upsetting the public even though they knew it would result in many deaths).

I am a Biologist. I am excited by the possibilities that GM opens up. I am also extremely wary of all information put out by the authorities. They spin and manipulate for their own ends.

What is Genetic Modification (GM)?

Science has progressed to the point where we are able to take a gene from one organism and put it into another.

That means we could take the chlorophyll producing gene and introduce it into humans. We would all become green and produce oxygen and sugar when exposed to light. Now that might be a silly idea and have lots of implications. But it is feasible. We could even introduce genes from jelly fish that would make us glow in the dark and cut down road deaths.

There is nothing intrinsically unnatural about this process. I mean – we are not manufacturing ‘new’ genes.

What it means is that any beneficial genes that have evolved in one species could be introduced into another.

That seems extremely useful so far.

The Benefits of GM

1. We could introduce a gene from one plant into another that would give it a defence against crop pests. This would save having to spray it with insecticide. That would prevent pollution and run-off of pesticides into waterways and prevent nearby plants being plastered with pesticides indiscriminately killing off bees and other insects.

2. We could introduce a gene that increased yield. This would result in more produce per acre and less land being needed to grow crops. It would enable us to feed people without encroaching on more wilderness and killing off wild-life and habitat.

3. We could introduce a gene that would enable crops to grow in arid lands. We could grow crops in deserts and not have to use water from rivers to irrigate. This would benefit aquatic wild-life. Fresh water is rapidly becoming a major problem. We have droughts and shortages.

4. We could introduce a herbicide resistance gene that would enable us to spray herbicides and reduce the need for weeding.

5. We could introduce genes that would fix nitrogen and enable plants to be grown in poor soil.

6. It would make farming less labour intensive. There would be less chemicals and less need to spray. This would reduce fossil fuel use.

7. We could introduce genes that would enrich the protein, vitamin and mineral content of food. We could produce crops with omega 3 fish oil. This would make food healthier.

8. We could introduce genes that would produce oil, plastic or other useful chemicals. This would reduce the need to drill or strip mine.

9. We could use the technique to introduce genes into human beings to treat terrible genetic diseases such as Huntingdon’s Chorea, Cystic Fibrosis or Haemophilia.

10. We could introduce genes that would enhance flavour or texture or give other benefits e.g. Golden Rice – a GM variety with a gene that produces Vitamin A (over a million children a year die from lack of Vitamin A – this would save them, their eyesight, and provide numerous other health benefits).

The Case against Genetic Modification (GM).

1. It is not natural. God would not like it.

2. It has been set up by huge multinational companies for profit. They are lying, cheating, unscrupulous and not to be trusted. They have a history of lying, bribing officials, using legal loopholes to flout legislation and spinning the downside. Their only interest is profit. They don’t care about people, health or wild-life.

3. It encourages large-scale farming and monoculture. This would be to the detriment of the small-scale farmer and biodiversity. It would encourage greater mechanisation.

4. There is a health risk from the products of these genes in our foods e.g. the chemicals the plants would produce to provide immunity against pests or as herbicide resistance might be harmful to animals or humans. It would end up in our food.

5. The herbicide tolerance promotes over-spraying with pesticide. The resultant residue on food is a health risk. The run off and airborne spray is a pollutant that would damage the environment.

6. There is a danger of cross-fertilisation and breeding introducing these genes into weeds, animals and plants that we do not want. We end up with weeds being immune to herbicide and get an even bigger problem.

7. There is a risk of transmigration of genes (via virus vectors) from the crops to other organisms. It would create huge resistance problems.

My view for what it is worth.

a. I do not trust multinationals. They have too much money and power. They can circumvent laws.

b. This is not a religious issue. Superstition should not come into it. This is science.

c. I think the transmigration and cross-fertilisation issues need objectively studying to see if there is a danger. I think there won’t be. These genes have been around for millions of years in the host organisms.

d. Likewise with the health issues.

e. I think the benefits outweigh the risks.

What I would like to see happen

1. I would like an independent overseeing body to regulate. They would have the power to look at all aspects and make judgements on global health and environmental basis.

2. I would like lots more research (unhampered by protesters) so that we can ascertain the facts about health risks, cross-fertilisation, transmigration etc.

3. I would like strict regulation, erring on the side of caution, with stiff penalties for transgression. This would create barriers for cross-fertilisation, establish impact on environment and regulate things such as chemical use and spraying.

4. I would like to see GM used wisely for the benefit of humans and everything else on this planet.

For me the production of sufficient food is crucial. We have a population spiralling out of control. We have to feed it. I am for anything that is more efficient so that we are less polluting and encroach on wilderness to a far lesser degree.

I believe, with due regulation and stringent enforcement, that it may be time to embrace GM.

What have I missed out?

What do you think?

Awesome Wonder – The beauty and majesty of space.

More galaxies that there are grains of sand on all the beaches on the planet. Each with trillions of stars and zillions of planets. Yet all this infinite universe is probable just one of an infinite number.

Inside each of those universes the laws of physics might be slightly different creating totally different scenarios.

We are here because everything was perfect for us to be here. Nowhere else could we have happened. We live in the goldilocks universe, on the goldilocks planet. Don’t you love it?

Glory in it. It is beautiful!  Hallelujah – Science is great!  Just love it for what it is!!

Isn’t that awesome? It is beyond our comprehension. We are bacterial scum on the surface on an insignificant planet, round a mundane sun, on the edge of a mediocre galaxy, in the midst of a mighty universe that is one of an infinite number.

Astounding!

The future and saviour of the world – Fusion energy!

 

fusion fusion 2

No not fracking or burning fossil fuels. That way leads to climate change and the same old scene.

Not even solar, wind and alternatives.

The future lies in Fusion. Once we have created the technology to do this industrially we will have unlimited power. It will be unpolluting and transformative.

We can have unlimited electricity for transport, producing fresh water to irrigate, and power to light the world.

It will lead to an age of plenty, the end of fundamentalism, migration, poverty and war.

Fusion is the future.

This is where we need to be investing big-time right now.

Fusion is beautiful! The sun works on it. We will bring a little sun on Earth. The old Sun Gods will be worshipped all over again (in a non-religious way).

Science and education are the saviours of mankind just as fundamentalism and fanaticism are its major threats.

Give me the power of fusion any day! Free energy for all mankind!

(The one caveat is that we will need to reduce our population so that there is room for the rest of life on this tiny planet!)

Zeitgeist. What it means to me. A mystery.

Happy Bulb
Happy Bulb

I use the term zeitgeist a lot. It has a particular resonance to me.

It is attributed to Georg Hegel but he did not actually use is. He talked of ‘the spirit of the time.’ Georg Hegel said that “no man can surpass his own time, for the spirit of his time is also his own spirit.”

I like that. For I am a child of the sixties. I grew in its energising atmosphere, ‘can do’ spirit and sense of adventure and change. The sixties for me was a time that was incredibly positive, creative and transforming. We chucked out the old values, discarded the establishment and tried to make our own culture and rules. It was liberal and liberating.

It is probably true that we are all stuck in the era we grew up in.

However, that is not quite what I mean when I use the term zeitgeist. I see it as something more. I am an antitheist. I believe all religion is created out of the minds of men and is used for power by the State and individuals. I have no belief in god or afterlives. Yet I do believe there are mysteries and unknown phenomena. The zeitgeist is one of those.

Somehow I think our minds are interconnected. We pool our mental resources into one common ‘mind’.

I am not talking about some crackpot telepathy here. I am not talking Science Fiction. I do not think it is either substantial or even spiritual. It is ethereal and yet it works.

The pooled collective of our consciousness creates the ‘vibe’ of the era. It also operates subtly to synchronise our thoughts.

I do not think it is merely chance that such synchronicity occurs. Simultaneously farming developed in China, India and the Middle East, likewise writing. When Darwin was working on his theory of evolution, at precisely the same time Alfred Wallace was doing the same thing. When Fleming was discovering penicillin there were simultaneous work going on elsewhere, likewise with DNA. Science is littered with people in different parts of the world coming up with the same idea at the same time.

When I was at college, rooming with a close friend, we rang each other up to tell each other about a great book we were reading only to find we were both reading the same book.

For me the zeitgeist is probably a scientifically provable mental emanation, weak but profound. I predict it will be discovered in the future. It connects us all. We contribute to it. Our positive thoughts can create the ‘vibe’ of the present. It is powerful stuff.

Even if it is not true I believe the zeitgeist exists. We can influence the people around us, create a positive atmosphere and improve the world; we can create the spirit of our time. We all count. We all contribute.

Wonder and Awe – Human Evolution.

evolution evolution6

We were not always alone as we are now. Although we share 99% of our genes with chimpanzees and gorillas, our closest living relatives, we are different. The prime difference being the size of our brains and our intelligence. Once there were a whole host of different humans.

We evolved in the Rift Valley in Ethiopia. We are all of African descent. We are all one species.

The fossil and DNA evidence is conclusive. Racists and creationists have nowhere to hide. All they can do is deny.

A mere five million years ago our common ancestor split off from the chimp line. The Australopithecines had a brain weight of 500 grams (slightly bigger than a chimp). By 1.8 million years ago there were numerous groups of hominids living in the Rift Valley region. We were not alone. They included Homo habilis and Homo erectus.

Life in the Rift Valley was precarious. There was a lot of climatic change.

By 1.4 million years ago only Homo erectus had survived. But their brain size had evolved to 1000 grams.

800,000 years ago Homo heidelbergensis had evolved. Their brain weight had jumped to 1400 grams (comparable to modern man). They gave rise to both the Neanderthals and Homo sapiens.

Homo sapiens evolved with a brain weight of 1500 grams only 200,000 years ago. We lived alongside our close, and more intelligent, cousins Homo Neanderthal until 45,000 years ago.

We have only been alone for 45,000 years. What a mess we’ve made of things in such a short time!

We are so new that if you took a baby from 200,000 years ago and brought them up in the present day they could be a nuclear scientist, president or rocket scientist without any trouble. We haven’t changed. Our brains are the same.

I like to imagine that somewhere, in a secluded garden of Eden, hidden away, a group of surviving Neanderthals have set up home. Despairing of the destructive violence of their cousins they cloistered themselves away.

I wonder what they would make of the world we have made and our invention of war, religion, pollution, overpopulation, politics, climate change, cruel ways to kill other animals and enough greed, selfishness and power-madness to destroy the planet.

Perhaps with their wisdom and intelligence they could convince us that there is a better way of living. We could take a lesson from the whales and dolphins. We could be gentle and live in a self-sustaining manner in harmony with each other and the planet.

I hope we find them soon. I’m scared of being alone with the megalomaniacs raging around me.

 

Wonder and Awe – Man and Intelligence.

brain

The saddest aspect of being a human being is that there is only one species of us. It has led us to believe we are something special, something that is above all other life. Many people struggle to think of us as animals.

We are animals. We are intelligent animals. We have fabulous brains that give us consciousness. We think that sets us apart. It doesn’t.

We are not the most intelligent animal that has ever lived on this planet, let alone what intelligences may exist on other worlds. We are not even the most intelligent organism on this planet now. We are not even the most intelligent species of human who has ever lived on this planet.

Brains operate like super-computers. It is the size that is important. Our brains contain 85 billion brain cells – neurons – which is about the same number of stars as in a small galaxy. However each of those cells is connected via dendrites to between 10,000 and a 100,000 other brain cells. That is a staggering number of connections.

The human brain is between 1300 grams (the racists) and 1400 grams (the rest of us).

By comparison the brain of a chimpanzee (our closest relative with whom we share 99% of our genes) is only 400 grams.

There was a rapid evolutionary change occurred around 1.8 million years ago (very recent in evolutionary terms). Our brains grew from 400 grams to 1400 grams.

I said earlier that we are not the most intelligent animal on the planet. That distinction falls to the cetaceans. Not all of us consider them super-intelligent because they do not build cities and weapons. That is how we judge intelligence.

Whales and dolphins do not have limbs to create tools. They live in the sea and do not need shelter. They have plentiful food and do not need to work.

They play, sing, spend time together and enjoy themselves. They do not pollute, overpopulate or destroy one another. They are not cruel, barbaric and vicious. They do not create religions.

That sounds like intelligence to me.

The size of a sperm whales brain  is a staggering 7800 grams. That is over five times that of a human.

The brain of a bottle-nose dolphin is between 1500-1700 grams – bigger than a human.

Of course you may like to suggest that intelligence is not all about brain size. The evidence from bird intelligence (with small brains) is that there are other factors though size is crucially important.

If you take into account body mass to brain ratio then we still do not come out too good. Even the tree shrew outdoes us.

The obvious intelligence of the cetaceans is extant in numerous ways and makes it even more disgusting when you consider the incredibly callous way we have treated them. We have deployed our technology to kill races of gentle, intelligent creatures. We have blown them up with explosive harpoons, stabbed and hacked them to death. In the Faroes they are still gaffing and sawing through their necks. The barbarity is appalling.

These creatures are probably more intelligent and sensitive than humans. Stop the slaughter!

It seems incredible to me that we spent billions trying to find even the most crudest form of life elsewhere in the galaxy while ignoring the obvious intelligent life under our own noses. Perhaps we should be trying harder to communicate?

Back to the subject.

I said earlier that we are not the most intelligent human that has lived on this planet. That accolade goes to the Neanderthals. We share a common ancestor and we even have some of their genes. There was some successful interbreeding. The Neanderthals, far from being the shambling cavemen of our cartoons, were more intelligent than us. Their brain size was 1500 grams to 1800 grams.

As more intelligent humans they were probably gentler. We – the moronic cousins – were more cynical and vicious. We lived side by side up until as recently as a mere 150,000 years ago. Then we destroyed them.

How I wish we hadn’t. Wouldn’t it be great if there were two intelligent species of human beings living on this planet now? It would blow all that religious superiority out of the water – particularly when we were clearly the lesser of the two in intelligence. The biblical stories would simply not hold water.

But that was not to be. We, the inferior intelligence, prevailed.

It goes to show that there is more to being human than intelligence.

Why haven’t we been able contact intelligent civilisations in space?

ALIENS-02-07-10-wb

The reason why we haven’t encountered or detected intelligent life on other planets is not because it hasn’t evolved elsewhere. It has probably evolved in our own galaxy hundreds of thousands of times.

The distances involved are so enormous it is impossible for the human mind to imagine but even that is not the main obstacle.

If there are intelligent civilisations out there is space they would be producing radio output that we would be able to detect.

Our technology is advanced enough to detect transmissions but it will take an enormous amount of time and effort to scan all the possible sources. Even so we should have found some trace by now.

My own view is that intelligent life has probably evolved hundreds of thousands of times but has been destroyed by its own stupidity.

Human beings have only been around as a species for a mere hundred thousand years. Civilisation only started up around 12,000 years ago. That is the blink of an eye.

In that twelve thousand years we have gone from primitive tools to space shuttles. We have nearly destroyed ourselves in the process and are likely to do so in the near future.

It is quite possible that civilisation only lasts for a short period of time before intelligent life kills itself with its own stupidity.

On Earth, in the brief period we have been ‘civilised’, we are now threatening our own existence in numerous ways:

a. We are overpopulating to unsustainable levels

b. We are polluting to levels that are dramatically altering climate

c. We have produced and used nuclear weapons and have enough stockpiled to eradicate life. We have lived through Mutually Assured Destruction for decades and have had the Cuban Missile Crisis that took us to the brink. It only takes an accident, a psychopath, terrorist or bad decision of brinkmanship and we could be precipitated into annihilation.

d. We are destroying habitat and species with abandon.

e. We have biological weapons that could wipe us out as a species.

f. We have insane religious fundamentalists who are quite prepared to wipe out human life in the belief that they are doing ‘God’s will’.

In some ways it is astounding we are still here. If humans are anything to go by it is quite probable that intelligent life is too stupid to survive long.

It is possible that we have never detected other intelligent life in our universe because it did not survive long enough to leave much of a trace. It wiped itself out before we got a chance to know it ever existed.

For us to detect other civilisations they have to have their brief flourishing at exactly the same time as ours. We would have to coincide.

That is probably more unlikely than all the other factors put together! For us to last another thousand years is probably statistically a greater improbability than life evolving into intelligence in the first place.

We are probably the only civilised intelligent life flourishing at this time!

That makes it all the more important to resist the madness of fundamentalist superstition, psychopathic leaders, sociopathic leaders and belligerent xenophobia and work towards a more egalitarian, harmonious equality in which we can all live happily.

Our one hope is that our intelligence is greater than our stupidity.

The jury is out on that one!

Can you imagine a universe without any intelligent life?

There’s the reality of our insane greed and beliefs.

 

Is there intelligence in space?

aliens_land_roswell_georgia_1165245While the possibility for life is hugely likely, given the immense time and enormous quantity of planets, the evolution of intelligence is another matter. That requires even greater overcoming of limitations. Intelligence requires sophisticated cells. There are immensely unlikely events on a par with that of the formation and incorporation of DNA.

On this planet the incorporation of DNA took place early on when the Earth had cooled and conditions were right. The formation of Eukaryotic cells (sophisticated cells that would support complex multi-celled life) requires two incredible occurrences. Firstly they have to incorporate or evolve cellular powerhouses to provide energy. On Earth this happened when bacteria (that were mitochondria-like) became symbiotically incorporated into cells. Secondly they have to have incorporated chlorophyll-rich chloroplasts to break down water to release oxygen and produce food.

The plants incorporated chlorophyll rich bacteria symbiotically. In so doing they changed the atmosphere of the planet and the oxygen enabled life to become more complex.

These two limiting factors are incredibly difficult leaps.

Not only do planets have to be in the ‘Goldilocks Zone’ and have given rise to life that incorporates DNA (or its equivalent) but it would also have to evolve through these two other immensely difficult bottle-necks in order to achieve the complexity necessary for intelligence.

The consensus is that this will only occur on an incredibly small number of occasions.

Fortunately with the billions of planets on which life will have occurred this still means that there are likely to be hundreds of thousands of planets out there supporting intelligent life.

There is intelligence out there! How do we contact it?

Is there life out there?

alien

In order for life to have evolved on a planet conditions have to be perfect. The planet has to be in a narrow band the right distance away from a sun. This is called the ‘Goldilocks Zone’ (not too hot and not too cold). Not only that but it has to be the right sort of star; one that will be stable and not give out devastating radiation.

That narrows the possibilities down substantially.

Fortunately the number of stars out there with planets in our own galaxy is trillions. When you narrow it down there are billions of suns with the right attributes and planets that exist in the ‘Goldilocks Zone’.

Given the early emergence of life on this planet shortly after it had cooled (it took one and a half billion years to cool and is now four and a half billion years old) it is extremely likely that there is life on hundreds of thousands of planets. The limiting factor here is the formation and incorporation of DNA (DeoxyriboNucleic Acid) to create the replication, information, organisation, mutation, change and stability necessary for life to reproduce and undergo evolution.

Time is the factor here. Given enough time (a billion years or so) anything that can happen does.

The consensus is that our galaxy alone is probably teeming with life. If it wasn’t for the vast, as yet insurmountable, distances involved we would already had discovered it. As it is we are unlikely to in the foreseeable future because distances between stars are too large. Even light takes hundreds and thousands of years to get here.

There are possibilities that we will discover extra-terrestrial life in our own solar system. It could be on Mars or the moon Europa. Time will tell. What we can be sure of is that this life is not likely to be as complex as us.

This life will probably be in the form of prokaryotic slime (bacterial scum).

We are not alone! There is life out there!

The bigger question is does this life ever evolve to create intelligence?

Heroes of the modern world – Nicolaus Copernicus – Opened up thinking for scientists and changed the universe.

Copernicus was a polish genius who was born in 1473.

At the time he was alive Europe was a theocracy. The Catholic Church had immense power and exerted it. It was heresy to refute the words of the Bible. If you denied Jesus was born of a virgin you could be vilely tortured and cruelly burnt to death.

The prevailing views of the church, based on the words of the Bible, was that the Earth was the centre of the universe, created by god. To say otherwise was heresy.

Ptolemy had set out a model for the Earth-centric solar system which was widely accepted. It worked except for the peculiar motions of the planets. He went to great length to try to explain this.

Copernicus realised and worked out mathematically that the Earth was not the centre of the solar system; it was circling the sun with the other planets. He did not publish his paper until on his deathbed for fear of ridicule and persecution.

Copernicus’s theory opened the door for other scientists to work out the true nature of the universe. Without him we were literally in the Dark of the Dark Ages. Religious fundamentalists are completely insane and intransigent when it comes to the words in their books. We see it today with US Creationists who claim the world is only a few thousand years old and men walked with dinosaurs. We see it with ISIL where beautiful history and culture, like the Buddhist Bamiyan statues, are being systematically destroyed because of texts.

The church had to be dragged screaming from its view that the Earth was flat, at the centre of the universe with the dome of heaven above behind which was the glory of heaven. Underneath was hell.

If it wasn’t for the heroism of Copernicus, Giordano Bruno and Galileo we’d still be wandering around in mediaeval costume, going to public burnings and being in ignorant rubbish.

Strangely it took sixty years for the Church to declare Copernicus’s work as heresy but then Giordano Bruno had his tongue pinioned, was tortured and burnt to death for believing it and Galileo nearly met the same fate under the Spanish Inquisition.

These men are heroes. They stood for truth in the face of the most vicious and intransigent fundamentalist theocrats. Without them we would not know the truth.

Fundamentalism (belief in the absolute truth of the word of religious texts), is obscene, ignorant, incorrect and has led to some of the worst atrocities.

Whether it is ISIS or the Creationists with their suits it is the same stupidity and barbarity. The truth is out there – not in ‘holy’ books.
