Stem Cells Could Create Humans-on-a-Chip
Researchers at the University of Florida have connected muscle tissue to the spinal cord using stem cells. The advance could revolutionize drug testing by creating micro-organs.
What's the Latest Development?
Using stem cells, University of Florida researchers have connected muscle fibers to spinal cord tissue, which is essential to the brain's ability to control muscle movement. The junction also plays an important role in Lou Gehrig's disease, spinal cord injury and other life-threatening conditions. "With further development, the team's techniques could be used to test new drugs or other treatments for these conditions." Further down the line, the research could revolutionize how all drugs are tested.
What's the Big Idea?
The stem cell research was funded by the NIH, FDA and DARPA, which is an experimental research and development agency operated by the military (they have also funded research on interstellar space travel). The goal of the research is to create "humans-on-a-chip". In other words, "systems that include various miniature organs connected in realistic ways to simulate human body function." Such chips could facilitate drug tests on human cells that would simulate an entire body before true human trials were ready to be carried out.

In his final years, Martin Luther King, Jr. become increasingly focused on the problem of poverty in America.
- Despite being widely known for his leadership role in the American civil rights movement, Martin Luther King, Jr. also played a central role in organizing the Poor People's Campaign of 1968.
- The campaign was one of the first to demand a guaranteed income for all poor families in America.
- Today, the idea of a universal basic income is increasingly popular, and King's arguments in support of the policy still make a good case some 50 years later.
10 of the most sandbagging, red-herring, and effective logical fallacies.
- Many an otherwise-worthwhile argument has been derailed by logical fallacies.
- Sometimes these fallacies are deliberate tricks, and sometimes just bad reasoning.
- Avoiding these traps makes disgreeing so much better.
For Damien Echols, tattoos are part of his existential armor.
- In prison Damien Echols was known by his number SK931, not his name, and had his hair sheared off. Stripped of his identity, the only thing he had left was his skin.
- This is why he began tattooing things that are meaningful to him — to carry a "suit of armor" made up the images of the people and objects that have significance to him, from his friends to talismans.
- Echols believes that all places are imbued with divinity: "If you interact with New York City as if there's an intelligence behind... then it will behave towards you the same way."
