Ferroptosis Findings Offer Hope for Cancer and Cell Protection

Scientists have uncovered a new pathway regulating cell death, or ferroptosis, which could pave the way for innovative cancer treatments. By examining how oxidative stress damages lipid membranes, the team found that the proteasome recycling system becomes clogged, accelerating cell destruction.

Does Stress Lead to Premature Hair Graying?

Hair turns grey due to a decrease in melanin production in hair follicles, a process influenced by both genetics and environmental factors like stress. Contrary to myths, plucking a grey hair won’t make more grow back, and hair can’t turn grey overnight.

Tau May Protect Brain Cells from Oxidative Damage

Researchers have discovered that the Tau protein, often linked to neurodegenerative diseases like Alzheimer's, also has a protective role in the brain. Tau helps combat oxidative stress by aiding in the formation of lipid droplets in glial cells, which sequester toxic lipids and protect neurons.

Motivation Is Affected by Oxidative Stress, but Nutrition Can Help

Higher levels of glutathione in the nucleus accumbens correlated with better and more steady performance in motivation-based tasks. Findings suggest improvements in accumbal anti-oxidant function that can be acquired via diet or supplementation may be a feasible approach to help boost motivation.

Iron Accumulation Linked With Age-Related Cognitive Decline

A breakdown in regulatory mechanisms causes iron to build up in the brain during aging, increasing oxidative stress and increasing the risk of age-related cognitive decline, a new study reports.

New Insights on ALS May Point To a Potentially Promising Treatment Strategy

Post-mortem studies of brain tissue from ALS patients reveal an abnormal form of tau is present in novel brain areas, and the tau interacts with DRP1. The tau appears to cause the brain cell's mitochondria to fragment and increase oxidative stress. Reducing tau reversed the effect, decreasing oxidative stress and mitochondrial fragmentation.

Fat Cells Found to Play a Central Role in Cognitive Decline and Neurodegeneration

A new study reveals how adipocytes, or fat cells, play a role in cognitive decline and increased neurodegeneration risks. Using genetically modified mouse models, researchers found oxidative stress through exposure to a Western diet increased the production of inflammatory cytokines confined to adipocytes and altered protein markers of memory and cognition in the hippocampus.
