Can Neuroplasticity Make Brains Young Again

Neuroplasticity is the process where the brain changes itself to provide new capacities. It is how memory and learning works. The Holy Grail of neuroscience is to find ways to enhance the brain’s ability to provide new capacities. Recently, there was found a possible way to re open the windows of enhanced learning that…

Cancers Produce New Distant Lymph Vessels for New Colonies

Cancers, like all cells, work in communities tied together through signaling. Like microbe communities they send and receive all kinds of signals for group behavior and for defense. They build their own unique organ with help from other cells. Recent research has shown that cancers enlist many other kinds of cells to work…

Circular DNA in Human Cells Adds Even More Complexity

The previous post noted new complexity in the regulation of DNA that was just discovered. As well as the many levels of regulation, physical properties helped regulate how DNA is used. Now there is yet another new development—circular DNA in human cells adds even more complexity. The number of ways that DNA is…

New Complexity in DNA Regulation

Which comes first the chicken or the egg? With proteins and RNA regulating the function of DNA and DNA producing RNA which then produces proteins, which comes first—DNA, RNA, or proteins? At first, the way DNA makes proteins seemed almost clear and simple—DNA makes RNA, which makes proteins in one direction. But,…
