Artificial Blood Within a Decade
The holy grail of blood research, man-made blood, will soon be tested on humans. Within a decade, it could supply much of the world's need, saving countless lives around the globe.
What's the Latest Development?
Biomedical researchers in England and Scotland have, for the first time, created thousands of millions of synthetic red blood cells using stem cells taken from bone marrow. While that count is still short of the amount necessary for a transfusion, scientists believe a teaspoon amount will be ready to inject into humans in a couple of years. Within a decade, they hope that artificial blood will be used routinely at accident sites and during surgeries. Ultimately, a stockpile of the O-negative blood type, known as the universal donor, should be created.
What's the Big Idea?
Creating industrial quantities of artificial blood could potentially end donation shortages, saving untold lives at the scenes of car accidents, on battlefields and in surgeries. Laboratories could adjust supply to fit demand; during the summer, for example, rates of car accidents are higher. A dramatic increase in supply could greatly benefit third world countries as well, where sub-standard medical conditions result in preventable deaths such as hemorrhaging during child birth.

Neuroscience research suggests it might be time to rethink our ideas about when exactly a child becomes an adult.
- Research suggests that most human brains take about 25 years to develop, though these rates can vary among men and women, and among individuals.
- Although the human brain matures in size during adolescence, important developments within the prefrontal cortex and other regions still take pace well into one's 20s.
- The findings raise complex ethical questions about the way our criminal justice systems punishes criminals in their late teens and early 20s.
Three scientists publish a paper proving that Mercury, not Venus, is the closest planet to Earth.
- Earth is the third planet from the Sun, so our closest neighbor must be planet two or four, right?
- Wrong! Neither Venus nor Mars is the right answer.
- Three scientists ran the numbers. In this YouTube video, one of them explains why our nearest neighbor is... Mercury!
A new method of growing mini-brains produces some startling results.
- Researchers find a new and inexpensive way to keep organoids growing for a year.
- Axons from the study's organoids attached themselves to embryonic mouse spinal cord cells.
- The mini-brains took control of muscles connected to the spinal cords.
