Nightmarish ‘supersoldier’ ants with huge heads and jaws have been created by activating ancient genes.

Scientists believe the monster ants may be a genetic throwback to an ancestor that lived millions of years ago.

Scientists say they can create the supersoldiers at will by dabbing normal ant larvae with a special hormone – the larvae then develop into supersoldiers rather than normal soldier or worker ants.

Supersoldier ants can occur naturally in the wild, but only rarely. In the deserts of America and Mexico, their job is to protect the colony from raids by invading army ants.

The supersoldiers use their enormous heads to block the nest entrance and attack any enemy ants that get too close.

Scientists showed that ordinary ants of the species Pheidole morrisi contain all the genetic ‘tools’ needed to turn them into supersoldiers – they just need a hormonal push.

The research is reported today in the journal Science.

Authors Dr Rajendhran Rajakumar, from McGill University, Canada, and colleagues wrote: ‘We uncovered an ancestral development potential to produce a novel supersoldier subcaste that has been retained throughout a hyperdiverse ant genus that evolved 35 to 60 million years ago.’

The results suggest that holding on to ancestral development toolkits may play an important role in evolving new physical traits, say the researchers.

A team of scientists in Oregon have announced the birth of a rare monkey, which they have termed the “chimeric monkey.”

Scientists at the Oregon National Primate Research Center created the chimera monkey, stitching together genetic material from six parents. By successfully implanting these genetically mixed rhesus monkey embryos into mothers, the scientists say that have now produced the first example in primates.

Until now, rodents have been the primary creatures used to make chimeras, a lab animal produced by combining two or more fertilized eggs or early embryos together. The chimeras have tissues and organs made up of cells that come from each of the contributing embryos.

“We need to go back to basics. We need to study not just cultured embryonic stem cells but also stem cells in embryos. It’s too soon to close the chapter on these cells,” said the study’s lead researchers. “If we want to move stem cell therapies from the lab to clinics and from the mouse to humans, we need to understand what these primate cells can and can’t do. We need to study them in humans, including human embryos.”

The monkeys were born from mixtures of very-early stage embryonic cells, suggesting that human embryonic stem cells may have developmental differences that could also produce similar results. The research is also thought to open the door for cloning primates using embryonic cells.

Scientists who know of the research said it was the breakthrough that they had all been waiting for because, until now, there was a growing feeling that there might be some insuperable barrier to creating cloned embryos from adult primates.

Scientists in South Korea reported in 2004 that they had created the first cloned human embryo, but it was discovered in 2006 that the study’s main author, Hwang Woo-suk, had committed fraud. The Oregon team, working with a group in China, has so far produced about 100 cloned embryos that have been transferred into around 50 female macaques, but none has resulted in a full-term pregnancy.

The breakthrough is sure to heighten the cloning controversy, and it comes as Oregon lawmakers are set to open the 2012 legislation session. The state has been at the center of the debate over cloning laws in recent years. Oregon State Representative Donna Nelson (R-McMinnville) put forth a measure in 2007, pushing for a ban on human cloning.

“Cloning human life under any circumstances crosses an ethical line from which science can never turn back,” said Representative Nelson at the time. “If we don’t take a stand now, if we don’t draw that ethical line clearly, we risk a future where new human beings are created for the sole purpose of harvesting organs or medical experimentation. This is an affront to the dignity of human life.”

The Oregon National Primate Research Center is one of the eight National Primate Research Centers in the United States. The center notes that its “mandate as a Center is to provide Nonhuman Primate (NHP) resources for the very best scientific programs, both within the Oregon Health & Science University community and beyond.”

(Author’s Note: This is NOT the first time this has been happening.  Dig a little deeper and you will find that the secret governments, under Black Operations, have been cloning, cross-breeding, dissecting humans, for a very long time and for nefarious reasons.)

Process could help detect birth defects in human children

Scientists have undone the progress made by evolution by altering chicken DNA to create embryos with alligator-like snouts instead of beaks.

Experts changed the DNA of chicken embryos in the early stage of their development, enabling them to undo evolutionary progress and give the creatures snouts which are thought to have been lost in the cretaceous period millions of years ago.

The scientific revelation of ‘rewinding’ evolution could pave the way for scientists altering DNA in the other direction and use the same process to create species better able to adapt to Earth’s climate.

It has also been claimed that the breakthrough could eventually help eliminate birth defects in human children.

Arkhat Abzhanov, an evolutionary biologist at Harvard University, developed the chickens with snouts by cutting a square hole in the shell of a chicken egg and dropping in a small gelatinous protein bead before watching the embryo develop.

The changes allowed separate molecules on the side of the face free to grow into snouts within 14 days.

Although ethical rules prevent the eggs from bring hatched, Dr Abzhanov said he hopes to complete the work one day by turning chickens into Maniraptora.

Dr Abzhanov made the changes by analysing the ‘signalling molecules’ which control the anatomical changes in birds and other animals.

Adding protein beads to the egg which stifle the development of certain molecules also prevents the birds from growing certain features.

Maniraptora are small dinosaurs which it is thought spawned thousands of species of birds which exist today.

Chickens and other birds are thought to have descended from dinosaurs through a series of genetic changes.

By altering the DNA of chickens to resemble alligator genes before the beak developed, Dr Abzhanov was able to change the evolutionary path of chickens so that they grew snouts instead.

Dr Abzhanov told the New Scientist: ‘It looks exactly like a snout looks in an alligator [at this stage].’

Jack Horner, a leading paleontologist based at the University of Montana, is conducting similar work in an attempt to make a ‘chickenosaurus‘ with a tail and hands similar to those of a dinosaur.

Craig Albertson, a developmental biologist at the University of Massachusetts in Amherst, said: ‘Abzhanov’s ‘snouted’ chicken provides a striking demonstration of just how easy it can be to provoke major evolutionary changes.’

Scientists have created more than 150 human-animal hybrid embryos in British laboratories.

The hybrids have been produced secretively over the past three years by researchers looking into possible cures for a wide range of diseases.

The revelation comes just a day after a committee of scientists warned of a nightmare ‘Planet of the Apes’ scenario in which work on human-animal creations goes too far.

Last night a campaigner against the excesses of medical research said he was disgusted that scientists were ‘dabbling in the grotesque’.

Figures seen by the Daily Mail show that 155 ‘admixed’ embryos, containing both human and animal genetic material, have been created since the introduction of the 2008 Human Fertilisation Embryology Act.

This legalised the creation of a variety of hybrids, including an animal egg fertilised by a human sperm; ‘cybrids’, in which a human nucleus is implanted into an animal cell; and ‘chimeras’, in which human cells are mixed with animal embryos.

Scientists say the techniques can be used to develop embryonic stem cells which can be used to treat a range of incurable illnesses.

Three labs in the UK – at King’s College London, Newcastle University and Warwick University – were granted licences to carry out the research after the Act came into force.

All have now stopped creating hybrid embryos due to a lack of funding, but scientists believe that there will be more such work in the future.

The figure was revealed to crossbench peer Lord Alton following a Parliamentary question.

Last night he said: ‘I argued in Parliament against the creation of human- animal hybrids as a matter of principle. None of the scientists who appeared before us could give us any justification in terms of treatment.

‘Ethically it can never be justifiable – it discredits us as a country. It is dabbling in the grotesque.

‘At every stage the justification from scientists has been: if only you allow us to do this, we will find cures for every illness known to mankind. This is emotional blackmail.

‘Of the 80 treatments and cures which have come about from stem cells, all have come from adult stem cells – not embryonic ones.
‘On moral and ethical grounds this fails; and on scientific and medical ones too.’

Josephine Quintavalle, of pro-life group Comment on Reproductive Ethics, said: ‘I am aghast that this is going on and we didn’t know anything about it.

‘Why have they kept this a secret? If they are proud of what they are doing, why do we need to ask Parliamentary questions for this to come to light?

‘The problem with many scientists is that they want to do things because they want to experiment. That is not a good enough rationale.’

Earlier this week, a group of leading scientists warned about ‘Planet of the Apes’ experiments. They called for new rules to prevent lab animals being given human attributes, for example by injecting human stem cells into the brains of primates.

But the lead author of their report,  Professor Robin Lovell-Badge, from the Medical Research Council’ s National Institute for Medical Research, said the scientists were not concerned about human-animal hybrid embryos because by law these have to be destroyed within 14 days.

He said: ‘The reason for doing these experiments is to understand more about early human development and come up with ways of curing serious diseases, and as a scientist I feel there is a moral imperative to pursue this research.

‘As long as we have sufficient controls – as we do in this country – we should be proud of the research.’

However, he called for stricter controls on another type of embryo research, in which animal embryos are implanted with a small amount of human genetic material.

Human-animal hybrids are also created in other countries, many of which have little or no regulation.
