Flu season has arrived – and so have updated flu vaccines
October 10, 2025
Every year, influenza – the flu – affects millions of people. Most will experience the infection as a mild to moderate illness – but for some, it can be severe, potentially resulting in hospitalization and even death.

As the autumn’s cool weather settles in, so does flu season – bringing with it the familiar experiences of sniffles, fever and cough. Every year, influenza – the flu – affects millions of people. Most will experience the infection as a mild to moderate illness – but for some, it can be severe, potentially resulting in hospitalization and even death.
New study links structural brain changes with cognitive, emotional, and physiological changes during menopause.
October 8, 2025
Menopause brings profound shifts not just in hormones but in the very structure of the brain. Scientists have found that gray matter in regions tied to memory and thinking can shrink, while white matter may show damage linked to blood flow issues. Yet there’s hope — evidence points to partial recovery and adaptive changes postmenopause.
Hyaluronic Acid Matrices for In Situ Measurement of Protein Diffusion Coefficients
October 7, 2025
In vitro measurement of protein diffusion within matrices that simulate the subcutaneous (SQ) environment is of interest, given that protein-based therapeutics formulated for SQ injection comprise the largest class of biologics.

Purdue undergraduate researcher explores how service animals can help promote psychosocial well-being of sexual assault survivors
Why women live longer than men, explained by evolution
October 1, 2025
An international team of researchers led by scientists from the Max Planck Institute for Evolutionary Anthropology in Leipzig, working with 15 collaborators around the world, has conducted the most comprehensive study yet of lifespan differences between the sexes in mammals and birds. Their findings shed new light on one of biology’s enduring mysteries: why males and females age differently.
A little stress could be the secret to healthy aging
October 1, 2025
Scientists discovered that specific nutrients in nematodes' diets activate stress defenses that keep their cells healthier over time. These RNAs prevent toxic protein buildup, promoting longevity and vitality. The worms fed with balanced diets lived more active, healthier lives. The findings hint that mild dietary stress could support better aging in humans as well.
Purdue Research Reveals Role of Fat in Brain Immune Cells and Potential Alzheimer’s Therapy
September 30, 2025
Recent research from Purdue University is challenging longstanding beliefs about the role of fat in the brain, particularly in relation to neurodegenerative diseases like Alzheimer’s. Findings published in the journal Immunity indicate that excess fat accumulation in microglia, the brain’s resident immune cells, significantly impairs their ability to combat disease. This insight suggests a new avenue for therapies targeting lipid biology, potentially enhancing microglial function and overall neuronal health.

Massive Datasets Meet Their Match
September 30, 2025
Just as streaming services have replaced CDs and DVDs by letting people watch or listen without downloading the content first, data streaming lets scientists analyze raw data from tools like microscopes and drones without needing to save the entire dataset beforehand.
