Modified rice has five times the zinc and iron and could help eliminate micronutrient deficiency to save over 1 million lives each year and boost GDP of poor nations over 20%

Being able to prevent anemia and micronutrient deficiency in nearly two billion poor people will save over a million lives each year, prevent stunting which reduces IQ and boost productivity and GDP by over 20%. Success in this public health area would be one of the biggest things in reducing world poverty and improving public health in those countries.

Iron and zinc deficiencies are widespread in the developing world and cause serious human disorders, such as child stunting, increased maternal mortality and iron-deficiency anaemia. In some communities, up to 80 percent of the diet comes from rice, which is a poor source of these vital nutrients. Zinc deficiency is a major cause of stunting among children. About 165 million children with stunted growth run a risk of compromised cognitive development and physical capability. The IQ scores of the severely stunted children at eight years of age were 11 points lower than those of the children who were not stunted. When the children in the study were tested again at age 11, those who had been most severely stunted at age 2 still scored lower on the intelligence test than children who had not been stunted, although the gap was narrower at about 5 IQ points. The World Health Organisation estimates two billion people, or 30 per cent of the world’s population, are anaemic, in many cases due to iron deficiency. This condition leaves people weak and lethargic and poses a significant and even fatal health risk to pregnant women and their children. Equal numbers are at risk of zinc deficiency with severe health consequences including stunted growth and impaired immune function.

CRISPR 101: A crash course on the revolutionary gene editing tool that’s changing the world

what is crispr a beginners guide dna editing

For something that’s been called “a household name for molecular biologists,” many of you have probably never heard of CRISPR, and don’t know why you should be excited (or, possibly, terrified). It’s all about advanced gene therapy and splicing – and it’s bringing sci-fi ideas straight into reality. Here’s a quick FAQ on the science behind CRISPR and why the world is paying such close attention.

Okay, what is CRISPR and what does it stand for?

CRISPR refers to unusual DNA sequences that help protect organisms by identifying threats – especially viruses – and attacking them. The name stands for Clustered Regularly Interspaced Short Palindromic Repeats. Yes, that sounds a little ridiculous, but it’s actually a very accurate description when looking at the DNA sequences themselves. They are clustered, they are spaced out at clear intervals, and when assigned letter values they do look like short palindromes repeating over and over with slight variations.

a couple of very good videos

the first is dealing with cancer and beer (the beer/designer yeast part is at 26 and 46 i think, the latter being more defined)

the second deals with the ultimate disease, aging (and cancer too)

Vaccine that targets second Alzheimers protein reverse the disease once it has developed, human trials in two to three years

Researchers at Adelaide’s Flinders University have made an Alzheimer’s breakthrough that may result in world’s first dementia vaccine. Developed by Australian and US scientists, this vaccine may not only prevent but also reverse early stages of Alzheimer’s, the most common form of dementia. The Alzheimer’s vaccine may be tested on humans within the next two to three years with US Government funding. Scientists from Flinders University and America’s Institute of Molecular Medicine and University of California developed the vaccine by targeting proteins in the brain that block neurons. The formula targets tau proteins and abnormal beta-amyloid that cause Alzheimer’s. The scientists are confident that the vaccine would eventually be used as preventative vaccine. According to Flinders University medicine professor Nikolai Petrovsky, the proteins must be removed from the brain as Alzheimer’s, and dementia sufferers have lots of these broken down proteins inside. The World Health Organisation (WHO) has projected a US$600 billion (AU$790 billion) cost per year as total global societal cost of dementia-related illnesses and care. The WHO also noted there are 7.7 million new cases every year. The first protein “to go wrong” was a-beta. However, targeting the second protein tau actually helped reverse the progression. Targeting the tau protein with the vaccine you can actually reverse the disease even once it has developed.

I think a lot of people take the decision to use nukes when they did, out of context. We were already fire-bombing the crap out of them and they still had no intentions of surrendering. They were in fact digging in and preparing to fight for every inch in the expected ground invasion in which it was estimated it would cost over a million american lives to accomplish. I am not saying it was the right thing, but one could argue that many lives were saved on both sides by bringing it to a swift end. Of course, no war at all is always the best option. There is an almost inevitability that someone will use technology to whatever means at some point. No one did use the a bomb on a population after us, which says something (so far).

This is true, but we always seem to learn the wrong lessons from it.

We look at the new and see the easy thing, the destruction. We don't see the difficult thing, the worthwhile thing, the one that makes the new our servant rather than our oppressor.

We look at fire and see burning trees, but not a warm home or safe food or bricks that won't melt in the rain.

We look at the atom and see mushroom clouds, but not the clean power that can replace fire and protect the planet from overusing it.

We look at biotechnology and see plague blankets, but miss the conquering of disease, the cures for congenital conditions, the feeding of the hungry without plowing up the entire earth.

We have primitive minds and instincts that tell us to fear everything. We need to see beyond what's easy and use our imaginations for more than conjuring demons in the dark. We need to let the beneficial develop, let it get ahead of the destructive. Because the people who want to use the new for destructive purposes already can—it's easy. It always is. We need to let people harness new technologies for good, and that takes more time and effort. It takes reason and curiosity and creativity rather than fear.

Or we can go back to shivering in the dark, afraid of the noises outside. That's easy too.

 
Some learn the wrong lessons from it (modern day Luddites, I guess you could say).

My point is that it is inappropriate to assume that the potential for good in new technologies has the intrinsic ability to prevent misuse, and that we don't need to take responsibility for ensuring that misuse is prevented or minimized. Science, like any tool, is value-neutral. We are compelled to concern ourselves with the motives and aims of those who pick up the tool to use it.
