Stem cells have the potential to change the face of healthcare. How can we generate these cells in the lab? This article gives a brief overview of induced pluripotent stem cell technology and how this can be applied to treat patients.
All organisms are composed of one or more cells. Although most living things we see are multicellular (made up of many cells) these are only a small fraction of all organisms on Earth. The vast majority of organisms are unicellular (only one cell), like the bacteria in your gut or the yeast that brew your beer. We humans are multicellular organisms made up of 3 trillion cells with more than 200 different cell types! The cost of this complexity is that when one or more cell types fail to do their job we get sick.
Cell biology seeks to understand how cells work and what happens when something goes wrong in a cell. By identifying what is causing a cell to not do its job, scientists can get a better idea about the inner life of the cell. They can also identify targets for therapies to fix what is wrong with the cell. These articles encompass the study of everything from tiny cellular machines to entire organs.
Most of your genome doesn’t code for proteins, but for viruses. Here we discuss their roles in controlling some basic aspects of human development.
We each have a powerful alarm clock in our cells that tells us when to sleep and when to be active – our circadian rhythm – and it’s wound differently for each person. In this article you’ll learn how circadian rhythm controls sleep, how a greatly altered circadian rhythm leads to sleep disorders, and the latest research on the genetics of sleep preferences.
Fluorescence generates vibrant colors that allows us to tell one cell from another, and even one biomolecule from another. This has led to great advances in our understanding of immunology by allowing us a peek into biological interactions at the cellular level.
An overview of how your cells build molecular clocks to maintain the daily cycles of your life.
