Neuroscientists reverse autism symptoms

Posted by in categories: biotech/medical, genetics, neuroscience

Autism has diverse genetic causes, most of which are still unknown. About 1 percent of people with autism are missing a gene called Shank3, which is critical for brain development. Without this gene, individuals develop typical autism symptoms including repetitive behavior and avoidance of social interactions.

In a study of mice, MIT researchers have now shown that they can reverse some of those behavioral symptoms by turning the gene back on later in life, allowing the brain to properly rewire itself.

“This suggests that even in the adult brain we have profound plasticity to some degree,” says Guoping Feng, an MIT professor of brain and cognitive sciences. “There is more and more evidence showing that some of the defects are indeed reversible, giving hope that we can develop treatment for autistic patients in the future.”

10-Minute Cancer Test is Possible Through Saliva

Posted by in categories: biotech/medical, genetics

Very interesting.


The current cancer tests involve numerous blood tests or a biopsy in order to sequence a tumor. Among the cancers that the tests could detect is pancreatic, which to date lacks effective early screening capabilities.

“Down the road it might be possible to test for multiple cancers at the same time”, Professor Wong added.

A group of scientists are calling on the WHO to classify aging as a disease, asserting that we need to create a better classification for what happens to our bodies as we get older.

A new controversy is brewing, as one group of scientists is recommending that aging be considered a disease.

Scientists say they’ve found a genetic ‘switch’ that could turn obesity on or off

Posted by in categories: biotech/medical, genetics

There’s still much that we don’t understand about obesity and its underlying causes, but scientists in Germany say they’ve discovered a genetic ‘switch’ that could effectively turn obesity on or off.

The new report is based on epigenetics research — that is, the way the genes in our bodies change based on chemical and environmental factors, rather than modifications in the fundamental DNA genetic code itself. We’re all born with a certain set of genes, but these can be turned on or off, or dialled up or down, though processes inside the body (it’s part of the reason why identical twins don’t always look identical).

It’s one of these epigenetic tags that the scientists have identified, and it works like a light switch rather than a dimmer. “Once the switch is triggered, it is a lifelong, epigenetically-driven decision that ends in a stable, either a lean or obese phenotype,” lead author Andrew Pospisilik from the Max Planck Institute of Immunobiology and Epigenetics. “The effect is akin to a light switch — on or off, lean or obese. Typically, we usually consider epigenetic control of disease to act much more like a dimmer, shifting phenotypes like body weight up or down gradually.”

Tinkering with Life : Genetics in the 21st Century

Posted by in categories: biotech/medical, genetics, life extension

I have nothing against the idea of designer babies. Why not better ourselves through science? There will always be a baseline version of humanity kicking around, even if it’s in cold storage,thus ensuring that any mistakes made early on don’t destroy the species. Besides, the same technology that allows us to make ourselves better could just as easily be used to repair us if we do make a mistake of some kind. TOO much red-tape, as always.


Room: B-3245.

Recent discoveries and advances in medicine are setting the bioethical world on fire. Some technologies, such as CRISPR-Cas9 and fast DNA sequencing techniques, have tremendously increased our control over our own genome. GMOs, Gene Therapy and life extension are examples of applications of our new gained knowledge in genetics. For more than a few, the thought of scientists playing with the fundamental building blocks of life brings an uneasy feeling. Yet, what are the scientists really doing?
