Cerebral Organoids

Science, in its quest for understanding the world around us, both within and without the human condition, has made great strides forward in developing techniques to better help us comprehend the complex structure and pathology of the human brain. One of these advancements are organoids.

Organoids are 3D cell cultures derived from pluripotent stem cells that mimic the structure, function, and cellular complexity of human organs. These in vitro, miniaturized versions of organs are especially well suited for studying complex multicellular organ structures, such as the brain, retina, kidney, and lungs, and are now widely used to study organ development and disease.

Recently scientists have for the first time grown mini-brains from fetal brain tissue that are about the size of a grain of rice. Tiny brains were previously grown from fetal stem cells but now, for the first time, from actual fetal brain tissue, opening exciting possibilities for the future.

A Little Light for the Clouded Enlightenment

Image: On Jeopardy facts win; The Paragraph

The United States is the world's first liberal democracy, a product of the The Enlightenment. As such, the founders built it on the principles of unity, liberty, tolerance and equal rights. And they designed it to make policy based on factual knowledge and bathed in the light of reason. But, today, in the time of Trump, factual knowledge is getting clouded over in several ways.

What is a republic? Foreword # 2

To truly understand a republic, and its importance in the political development of humanity, you must appreciate the role of science. So let me ask this:

What do you think our government, our national policies, our national reputation and our political prospects would look like if 28 Senators and 162 Congressmen (or some similar number) were world leading scientists?
