Even more so than coffee, tea is the most popular drink in the world, barring alcohol itself. Its history stretches back thousands of years and across dozens of cultures. The caffeine within and the multiple health benefits from regular consumption have helped continue its popularity to this day. But that popularity includes an ever increasing […]
The human immune system is usually a tireless worker that does its best to keep us protected from pathogen invasion. But even for all of its complexity, there are certain parts of it that fail hard when confronted. Enemy Identification When it comes to combating bacteria wishing to harm us, one of the first actions […]
Water is important for life. It is a primary source of structure and function in all life forms, even including viruses that use it as interstitial fluid for containing their viral genome. For organisms that produce their own complex compounds, commonly known as autotrophs, water remains the main source of outside material they need to […]
Stem cells were often thought of as the holy grail of biological discovery after they were uncovered by Ernest McCulloch and James Till in 1963. A method to produce cells that can form into any part of the body, potentially providing new organs and prevent horrible disorders like leukemia. Of course, things didn’t really turn […]
The central dogma of molecular biology and genetics is pretty straightforward. You take DNA, then you transcribe the desired gene into RNA (usually mRNA) and, once outside of the nucleus, you translate that RNA using ribosomes into amino acids that then form proteins. Those proteins then do the actual function that their original genetic encoding […]
Synthetic biology is complicated. When you’re building biological systems from the ground up, how could it not be? But the results are almost always something amazing, a real revolutionary accomplishment that wouldn’t be possible with any other field of science. The only other field that comes close is nanotechnology and mechanical systems are still somewhat […]
We’ve discussed the creation of electronic plants recently and the idea of using plants as electrical storage and transferring devices, allowing an electric connection from, say, one end of a garden or field to another. But plants can transfer far more than just electricity. They are already masters at transferring necessary nutrients from the soil […]
It is a simple fact of science that over evolutionary time, such as thousands or even millions of years, an organism’s diet can influence and alter its genetics to make it more adapted toward the food it eats. The Effects of Agriculture There is a natural assumption that the same is true for humans, as […]
Ants are fascinating. As examples of highly social, structured, and often single-minded species, ants easily pique the interest of biologists and even scientists as a whole. Similar to bees, their colony structure exists as highly divergent from the rest of the multicellular life in the world. Most of it, at least. They can be viewed, […]
Cloning is a difficult process. Even with modern technologies, the best we can do is generate matching organs from a person’s stem cells, but this itself is still tricky to accomplish. Actually cloning a whole organism? We’re nowhere near where we need to be. The Troubles of Cloning The main problem inherent in this process […]
