This sensitive and rapid platform may outperform current techniques and thus shed light on the involvement of oxidative damage in each of these diseases.

Researchers used the MagLab to produce the first clarified map of KRAS proteins in colon cancer tumors. Twenty-eight additional forms of the KRAS protein were discovered, including a new form of the protein (called clipped-KRAS) that does not bind to the cell membrane, instead serving as a kind of on-off switch to regulate cell growth. These findings may help yield future cancer treatments.

Here, researchers used deuterium magnetic resonance to study dietary influences on lipid synthesis demonstrating that high fat ketogenic diets significantly slow de novo lipogenesis, a process by which excess carbohydrates are covered into fatty acids and stored as triacylglycerols.
An insect's ability to survive anaerobic conditions (without oxygen) during winter pupation occurs through periodic cycling of aerobic respiration pathways needed to recharge energy and clear waste. The cellular mechanisms at play during these brief near-arousal periods can provide clues to help improve the success in storage and transplant of human organs.
