Fremtidens sykebehandling kan gi utrolige muligheter , dette blir spennende om det lykkes.
Nytt verktøy for genredigering skal kunne fikse de mest skadelige DNA-mutasjonene
Forskere har funnet opp et nytt verktøy for å redigere gener, som gir nytt håp om å kunne behandle mennesker med genetiske lidelser. I teorien kan det kraftige nye molekylære verktøyet rette opp i de aller fleste mutasjoner som forårsaker genetiske sykdommer hos mennesker.
Metoden som kalles «prime editing» kan reparere rundt 89 prosent av de 75.000 skadelige mutasjonene som man kjenner til at fører til ødeleggelser i det menneskelige genom. Mutasjoner som kan lede til tilstander som cystisk fibrose, sigdcelleanemi og den dødelige nervesykdommen Tay-Sachs sykdom.
Det banebrytende arbeidet åpner dørene til en ny epoke med redigering av genomet, men forskere understreker at mer forskning er nødvendig før metoden trygt kan brukes på mennesker. I tillegg til å bevise at det er trygt, må man også finne ut hvordan man skal levere tilstrekkelige mengder av det molekylære maskineriet til celler for å behandle en lidelse.

How Your Thoughts Change Your Brain, Cells and Genes
Every minute of every day, your body is physically reacting, literally changing, in response to the thoughts that run through your mind.

Every minute of every day, your body is physically reacting, literally changing, in response to the thoughts that run through your mind.
It's been shown over and over again that just thinking about something can cause your brain to release neurotransmitters, chemical messengers that allow it to communicate with parts of itself and your nervous system. Neurotransmitters control virtually all of your body's functions, from hormones to digestion to feeling happy, sad, or stressed.
Studies have shown that thoughts alone can improve vision, fitness, and strength. The placebo effect, as observed with fake operations and sham drugs, for example, works because of the power of thought. Expectancies and learned associations have been shown to change brain chemistry and circuitry which results in real physiological and cognitive outcomes, such as less fatigue, lower immune system reaction, elevated hormone levels, and reduced anxiety.
In The Intention Experiment: Using Your Thoughts to Change Your Life and the World, Lynne McTaggart writes:
A sizable body of research exploring the nature of consciousness, carried on for more than thirty years in prestigious scientific institutions around the world, shows that thoughts are capable of affecting everything from the simplest machines to the most complex living beings. This evidence suggests that human thoughts and intentions are an actual physical "something" with astonishing power to change our world. Every thought we have is tangible energy with the power to transform. A thought is not only a thing; a thought is a thing that influences other things.

Det er lov å si det så lenge det ikke kommer fra Dureken.
