Dear /sci/, I propose that lipid membranes do not exist. Here is some of my reasoning:
http://jp.physoc.org/content/280/1/105.short >Cutting a cell in half and exposing the cut face to a solution of sodium and potassium does not change solute concentrations significantly
http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1072717/pdf/jcinvest00750-0067.pdf >Rubidium replaces potassium within a cell. Cesium replaces both. If potassium is accumulated due to an inward pumping, other solutes should not affect this.

I propose you should stop posting the same thing >here is experimental evidence against the membrane-pump theory for the maintenance of high K+ and low Na+ concentrations in resting cells. Ling has shown (1962) that under specified conditions, the Na pump alone would consume 1530 times the total energy available to the cell. >This objection to the steady-state model, presented in detail fifteen years ago (Ling, 1962), has been confirmed in general principle by Jones (1965) and Minkoff & Damadian (1973, 1974).

>The worry is that changing the DNA of the next generation is unsafe and a slippery slope toward eugenics. Yet many of the scientists attending the Washington meeting won’t be there to ban the technology, but to trade tips about how, exactly, they might be able to do it right.

>>7686439 There is a 50/50 chance that a defective gene from an egg will be passed on, I think. So create embryos until one doesn't have that gene. That doesn't require gene editing, only gene screening.
>>7686272 A single socket already creates a circuit. The input and output wires are contained within one cable, this is why sockets have two prongs (and sometimes a third for grounding).
How do you train your brains? I mean exercises and whatnot. Currently i'm playing this BrainWars apps but can't tell if increasing scores may have any influence on daily activities. Do you maybe know any better free apps for android?
Brain training games don't help you in general. They help you become good at those specific games. The only proven brain training technique is N back tests.
Couldn't one simply grow a superintelligent mind by growing neurons in a large enough vat with a built-in vascular network to bring in nutrients and oxygen and remove carbon dioxide?
Brain tumors are made up of neurons or glial cells and they replicate very well:
https://en.wikipedia.org/wiki/Brain_tumor
And they can already grow tiny brains with all the right specialized tissues in labs:
The researchers above claim that its difficult to grow brains any bigger without a vascular network. However, blood vessels have been successfully made from stem cells:
And two-way transmission of electrical signals between neurons and computer chips have been shown to work as well which should provide the "super-brain" with efferent and afferent processes as well as a way to receive and send out information:
Does anyone else feel that genetics and especially molecular genetics as a field has become a failure?
Looking at the progress we made between the early 80s and late 90s, you'd think that we'd be living in a Gattaca-esque society by now.
In the 80s, we had the first PCR machines, Sanger sequencing, and sequencing of the first non-human genomes.
In the 90s, we had the first cloned mammals, then the first cloned large human-like mammal (Dolly), the first DNA microarrays, the Human Genome Project was in full swing, the first genetically modified foods... Comment too long. Click here to view the full text.
I feel it has become a failure in that it can be used to promote racism. We live in a gattaca-esque society but not to those extremes. Eugenics is a big part of our diet. I remember one of my Jewish teachers whose parents suffered in Germany because of their very dark skin always used to accuse Gerber of promoting racial inequality; comparable to Nazi Germany. When I was little, I had abs and was pretty buff, naturally. So we would go to places and people would start praising it. My mother hated it. She saw it as wrong for society to treat people different because of their appearance... Comment too long. Click here to view the full text.

When the treaty preventing Antarctic development expires in 2050 I expect there will be some attempts to properly settle it by Russia at least
What technologies would it require to build a stable, safe city on top of ice, to power it and keep shit from freezing? Would you want to live someplace with a remarkable view, but where it is difficult/dangerous to go outdoors? Assume the interiors of the buildings are all super attractive and cozy.
Any books on how to optimally lead a nation and manage resources and security. Perferably something unlike a your business management / corporate strategy books. More math based strategizing techniques.Im really interested in this concept.
It is a clear example of why science is a patriarchal construct of a male dominated society. It boils down the cultural identity of minorty groups into ideas that anyone can use! A clear example of white people appropriating the ideas of oppressed colored people.
