A mitochondrial self-preservation mechanism
Mitochondria, the powerhouse of the cell, convert sustenance into energy, fueling the cell's activities. In addition to power, mitochondria also produce reactive oxygen species, byproduct molecules primed to help facilitate communication among the ot.....»»
Ice 0: Researchers discover a new mechanism for ice formation
Ice is far more complicated than most of us realize, with over 20 different varieties known to science, forming under various combinations of pressure and temperature. The kind we use to chill our drinks is known as ice I, and it's one of the few for.....»»
Nanoscopic imaging aids in understanding protein, tissue preservation in ancient bones
A pilot study from North Carolina State University shows that nanoscopic 3D imaging of ancient bone not only provides further insight into the changes soft tissues undergo during fossilization, it also has potential as a fast, practical way to determ.....»»
Discovery of Piezo1"s new signaling mechanism may aid search for better pain and itch treatments
The human body's sense of touch is so important it can be found throughout the body, not just on the skin. Two tiny sensors of touch, Piezo1 and Piezo2, signal the lightest pressures and can be found monitoring the circulatory system, telling the bod.....»»
Researchers zero in on the underlying mechanism that causes alloys to crack when exposed to hydrogen-rich environments
When deciding what material to use for infrastructure projects, metals are often selected for their durability. However, if placed in a hydrogen-rich environment, like water, metals can become brittle and fail. Since the mid-19th century, this phenom.....»»
