Scientists finally uncover why statins can cause muscle pain

5 hours 30 minutes ago
Scientists have uncovered a surprising reason why statins, the widely prescribed cholesterol-lowering drugs that help prevent heart attacks and strokes, can sometimes cause muscle pain, weakness, and even severe muscle damage. Using advanced imaging technology, researchers discovered that statins can attach to a crucial protein in muscle cells and force open a channel that normally controls calcium flow. This causes calcium to leak continuously, potentially damaging muscle tissue.

Your aging brain may be trading memory for something more valuable

6 hours 59 minutes ago
The aging brain may be undergoing a remarkable transformation rather than simply losing its abilities, shifting its focus from remembering details to understanding the bigger picture. Scientists suggest this change could be an evolutionary adaptation that helps older adults develop wisdom and share decades of knowledge with younger generations.

Atherosclerotic cardiovascular disease risk is associated with AT(N)V neuroimaging biomarkers and cognitive impairment in the health and aging brain study-health disparities cohort

8 hours 31 minutes ago
CONCLUSION: In this diverse HABS-HD sample, increasing ten-year ASCVD risk was associated with greater AT(N)-V biomarker burden and poorer cognitive performance across multiple domains. These cross-sectional findings suggest that ten-year ASCVD risk may serve as a marker of co-occurring cardiovascular and brain health burden, but they do not establish causality or temporal direction.

Established determinants of replicative lifespan, including mitochondrial DNA, play a limited role in early yeast stress-resistance decline

8 hours 31 minutes ago
Baker's yeast is a long-standing model for studying mechanisms of aging. Due to asymmetric division, yeast mother and daughter cells are distinguishable, and mother cells usually cease division after 15-25 budding events. However, yeast suspensions consist predominantly of young cells. Here we investigated whether, under harsh environmental conditions, replicative aging-defined by the number of buds produced-manifests at early replicative ages. To test this, we adapted a flow-cytometry-based...

Scientists discover a surprising link between vitamin C and cancer survival

14 hours 9 minutes ago
A surprising clinical trial suggests that taking vitamin C daily could improve survival in people with precancerous blood disorders and early-stage blood cancers. Patients receiving the supplement had fewer adverse events and showed a promising survival advantage, raising hopes that a common vitamin could help protect against leukemia-related complications.
