How to create a genius mouse

Posted by in categories: genetics, neuroscience

The left-brain hemisphere of a normal mouse shows the normal level and cellular distribution of the Pax6 gene expression in the developing neocortex. The right-brain hemisphere shows a sustained, primate-like Pax6 expression pattern in the neocortex of a double transgenic mouse embryo. These animals have more Pax6-positive progenitor cells and a higher Pax6 expression level in the germinal layer close to the ventricle in the right hemisphere.

Researchers at the Max Planck Institute of Molecular Cell Biology and Genetics have created a transgenic mouse in which a gene called Pax6, during embryonic development, is highly expressed in a specific group of brain cortical cells called neural progenitor stem cells (the cells that generate all cells that make up the brain).

The resulting mouse brain generated more neurons than normal and exhibited primate-like features — notably those in the top layer, a characteristic feature of an expanded neocortex.

Move over, autonomous AI weapons, there’s a new risk in town: ‘gene drives’

Posted by in categories: bioengineering, biotech/medical, genetics, robotics/AI

Wyss Institute scientists believe that synthetic gene drives, if researched responsibly, might be used in the future to render mosquito populations unable to transmit malaria (credit: CDC)

An international group of 26 experts, including prominent genetic engineers and fruit fly geneticists, has unanimously recommended a series of preemptive measures to safeguard gene drive research from accidental (or intentional) release from laboratories.

RNA-guided gene drives are genetic elements — found naturally in the genomes of most of the world’s organisms — that increase the chance of the gene they carry being passed on to all offspring. So they can quickly spread through populations if not controlled.

Affordable genetic diagnostic technique for target DNA analysis developed

Posted by in categories: biotech/medical, chemistry, engineering, genetics

Professor Hyun-Gyu Park of the Department of Chemical and Biomolecular Engineering at Korea Advanced Institute of Science and Technology (KAIST) has developed a technique to analyze various target DNAs using an aptamer, a DNA fragment that can recognize and bind to a specific protein or enzyme. This technique will allow the development of affordable genetic diagnosis for new bacteria or virus, such as Middle Ease Respiratory Syndrome (MERS). The research findings were published in the June issue of Chemical Communications, issued by the Royal Society of Chemistry in the United Kingdom. The paper was selected as a lead article of the journal.

Closer to God

Posted by in categories: entertainment, genetics

Dr. Victor Reed is a brilliant geneticist who has just achieved a huge scientific breakthrough by successfully cloning the first human being, an adorable baby girl named Elizabeth. This immediately becomes a media spectacle and ignites a firestorm of debate concerning the moral and religious implications of such a discovery. Soon, Dr. Reed and his family lose all sense of privacy and safety as they are swarmed by protesters and the media. Their biggest threat, however, could be Victor’s own secret.

It is Unethical Not to Use Genetic Engineering

Posted by in categories: ethics, genetics, health, robotics/AI, space

When I hear that the conversation is about an ethical problem I anticipate that right now the people are going to put everything upside down and end with common sense. Appealing to ethics has always been the weapon of conservatism, the last resort of imbecility.

How does it work? At the beginning you have some ideas, but in the end it’s always a “no”. The person speaking on the behalf of ethics or bioethics is always against the progress, because he or she is being based on their own conjectures. What if the GMO foods will crawl out of the garden beds and eat us all? What if there will be inequality when some will use genetic engineering for their kids and some won’t? Let’s then close down the schools and universities – the main source of inequality. What if some will get the education and other won’t?

That’s exactly the position that ‪Elon Musk took by fearing the advances in genetic engineering. Well, first of all, there already is plenty of inequality. It is mediated by social system, limited resources and genetic diversity. First of all, why should we strive for total equality? More precisely, why does the plank of equality has to be based on a low intellectual level? How bad is a world where the majority of people are scientists? How bad is a world where people live thousands of years and explore deep space? It’s actually genetic engineering that gives us these chances. From the ‪#‎ethics‬ point of view things are visa versa. It’s refusing the very possibility of helping people is a terrible deed. Let’s not improve a person, because if we do what if this person becomes better than everybody else? Let’s not treat this person, because if we do he might live longer than everybody else? Isn’t this complete nonsense?

World’s first biolimb … By Akshat Rathi | Quartz

The idea is simple. First, they take an arm from a dead rat and put it through a process of decellularization using detergents. This leaves behind a white scaffold. The scaffold is key because no artificial reconstructions come close to replicating the intricacies of a natural one.

Fours Stages of Curing Aging

Posted by in categories: genetics, life extension

Curing aging has 4 stages: mild aging deceleration, dramatic aging deceleration, achieving negligible senescence and rejuvenation. Today we can definitively claim that the task of mild aging deceleration is theoretically solved.

We know the drugs and interventions that slow down aging in mammals. The only thing that we don’t know is dosages, regimes and drug combinations. Defining all of that is the goal of pre-clinical and clinical studies. They can be started immediately. It is also a good idea to do clinical studies of various diets aimed at improving human longevity.

Dramatic aging deceleration will be achieved using gene therapy. Breakthrough studies of lifespan extension in old model animals happened in this area quite recently. We know the genes and delivery methods, now we need a set of powerful experiments aimed at radical life extension. The subject of the intervention will not only be the human genome, but the genomes of the human microbiota.
