Cell death is, ironically, an essential part of life. In recent years, the study and understanding of cell death pathways has been dramatically transformed by the insights gained into non-apoptotic pathways, including necro-apoptosis and autophagy, together with a deeper understanding of the mechanism of the apoptotic cascade. New discoveries have been enabled by cutting-edge technologies, particularly in the realm of cytometry and cell-death–specific markers. In this webinar, the latest insights into cell death pathways will be discussed, including the molecular markers and cellular changes that characterize each pathway. Viewers will also learn practical cytometry-based strategies for dissecting cell death pathways, and how to use the data to better understand the pathophysiology of diseases such as cancer as well as to uncover new targets for drug discovery and development.

On another occurence some scientists found that cells could be manipulated with light:

Researchers at Washington University School of Medicine in St. Louis have discovered a way to make cells move, marking an important first step towards using light as a means of controlling insulin secretion and heart rate.
Dr. N Gautam, PhD, a professor at the school’s department of Anesthesiology, explains that the light functions as an on-off switch for the cells “Much of the way cells behave is due to their ability to sense signals in the environment. In these experiments, what the cells sense is the presence of light.
