The colleagues reported in Cell Reports Physical Science that by building a structure out of DNA and then coating it with glass, they have created a very strong material with very low density.
They use self-assembling DNA to build a lattice, which is then doped with microscopic glass. It's kind of like reinforced concrete but at the molecular scale. Scaling it up will be the hard part but the technique is pretty innovative.
I saw a YouTube video a while ago about 3d printing structures with organic filaments. Now self replicating DNA composites… it’s interesting and a bit unsettling to think of a future where buildings may be literally alive.
I always find it weird when they say stuff like something is 5 times lighter than something else. Or it’s 10 times cheaper than something else. It seems better to say scientists have invented a new material that weighs 1/5 as much as steel.
Yeah. You can’t x by a positive number and end up with a product that’s smaller than x. It’s literally incorrect, even though they obviously mean it’s one fifth rather than “five times”
This is good, but where is the company that left this crumbling wreck? Who was responsible for it when it was abandoned? Yes, the oil belongs to a country with a government in flux, but surely the crew where part of a corporation or business of some sort.
Absolutely it is big news! If you know what your future holds you can plan for it. This means getting your affairs in order, taking that trip across Europe you’ve always wanted to do now instead of when you were planning at 65 (when you might be disabled from Parkinson).
On the scientific front, early detection would also let researchers learn how the disease progresses and could unlock new treatments to slow or stop the disease in earlier stages that we can’t do right now because we detect the disease too late.
Parkinsons can be controlled decently through early intervention, at least compared to Alzheimer's. It could be the difference between 10 additional years with some quality of life or not.
