Recent research suggests that drinking orange juice can benefit heart health by lowering blood pressure and inflammation, and improving fat metabolism, with effects varying based on body type. The study highlights molecular mechanisms behind these benefits, though moderation is advised due to sugar content, and whole fruits are recommended over juice for additional fiber and nutrients.

Researchers are exploring the potential of repurposing cancer drugs, specifically letrozole and irinotecan, to treat Alzheimer's disease. A study identified these drugs as promising candidates that may slow or reverse symptoms in mice by altering gene expression related to the disease. While initial results are encouraging, further clinical trials are needed to assess safety and effectiveness in humans, considering the significant side effects of these drugs.

Researchers at Rutgers University have mapped the alignment of different brain cell types with functional networks in the human cortex using post-mortem gene expression atlases. This study links cellular distributions to networks involved in sensory processing and decision-making, enhancing our understanding of brain organization and its implications for cognition and mental health. The findings, published in Nature Neuroscience, provide a framework for future research on the cellular basis of brain function and disorders.

A study published in eNeuro suggests that alcohol consumption may accelerate the progression of Alzheimer's disease by affecting similar gene expression patterns in the brain. Researchers found that both Alzheimer's and alcohol use disorder (AUD) involve dysregulated genes and pathways related to inflammation, cell signaling, and cell death. The study analyzed RNA sequencing data from brain cells of Alzheimer's patients and found similarities with those affected by AUD. While the findings highlight alcohol as a potential risk factor for Alzheimer's, further research with larger datasets is needed to confirm these results.
