Gene editing has already been used to fight diseases, but there’s now hope that it might eliminate the diseases altgether. Researchers have shown that it’s possible to eliminate facial muscular dystrophy using a newer editing technique, CRISPR (Clusters of Regularly Interspaced Short Palindromic Repeats) to replace the offending gene and ‘turn off’ the condition. The approach sends a mix of protein and RNA to bind to a gene and give it an overhaul.

This doesn’t mean that doctors suddenly have a cure-all on their hands. They haven’t tried CRISPR on real live people, and there’s no guarantee that it’d work with every genetic condition under the Sun. The initial test was only 50 percent effective, too. If this gene mending is useful in the field, though, it could do a lot to transform medicine. Doctors could treat the root cause of a genetic disease rather than deal with the symptoms, and possibly wipe it out entirely — or at least, make it more bearable.

A few weeks ago, I wrote about Ray Kurzweil’s wild prediction that in the 2030s, nanobots will connect our brains to the cloud, merging biology with the digital world.

Let’s talk about what’s happening today.

Over the past few decades, billions of dollars have been poured into three areas of research: neuroprosthetics, brain-computer interfaces and optogenetics.

Memories are priceless, and the plight of dementia patients highlights how important they are to forming what makes us, well us. Now a new study has provided hope we may one day be able to restore lost memories.

Clearing the mist

A paper from researchers at MIT has demonstrated the reactivation of memories in amnesia patients with optogenetics — in which cell activity is controlled by bursts of light.

I had read about Singapore in genetic engineering way back in the 90’s. I think they were 1st or 2nd in making immortal skin cells at the time.

Singapore scientists have unravelled a mystery that could pave the way for turning back the clock on ageing.

A recent study led by Dr Ng Shyh Chang of the Genome Institute of Singapore at the Agency for Science, Technology and Research (A*Star) has found a gene in human egg cells that suppresses an enzyme causing cells to age.

This animation depicts the CRISPR-Cas9 method for genome editing – a powerful new technology with many applications in biomedical research, including the potential to treat human genetic disease. Feng Zhang, a leader in the development of this technology, is a faculty member at MIT, an investigator at the McGovern Institute for Brain Research, and a core member of the Broad Institute. Further information can be found on Prof. Zhang’s website at http://zlab.mit.edu.

Might be a good start point for some new longevity research.

A new genetic analysis of human gut bacteria is turning up some really weird critters—so weird, in fact, that some biologists are speculating we’ve found an entirely new domain of life. We should take that possibility with a healthy dose of skepticism. But here’s why it’s even being discussed.

In the past ten years, new genomic technologies have, for the first time, enabled scientists to explore our microbiome—that trove of invisible critters that live on us and in us. Microbiome research is quite literally rewriting the textbooks on human biology, as we learn that everything from our mouths to our intestines to our skin is, in fact a complex and diverse ecosystem. Hell, we’re even surrounded in a personal cloud of bacteria. By some estimates, the human cells in your body are vastly outnumbered by microbes.
