Sharing Genetic Risk Scores Can Unwittingly Reveal Secrets
Genetic risk scores, which condense millions of DNA variants into a single health probability, can be reverse‑engineered to approximate the underlying genotype. Researchers show that mathematical techniques using reference panels can reconstruct DNA from these scores, exposing private health information. Health insurers could exploit reconstructed profiles to adjust premiums, while individuals posting scores publicly risk re‑identification through genealogy databases. The findings highlight a privacy paradox where useful summaries also act as genomic fingerprints.
Frailty Sets in Far Earlier than You’d Expect, but You Can Reverse It
New research reveals frailty can begin decades before old age, with many people in their 30s and 40s already in a pre‑frail state. Around 10 % of those in their 50s show early signs, rising to about half of individuals in...
A Daily Multivitamin May Slightly Slow Rates of Ageing
Researchers conducted a double‑blind, placebo‑controlled trial with 1,000 participants averaging 70 years old, giving half a daily multivitamin (Centrum Silver) and the other half a placebo. After two years, analysis of five epigenetic aging clocks indicated the supplement group aged...
Inflammation Might Cause Alzheimer's – Here's How to Reduce It
Recent studies suggest that persistent inflammation in the gut, lungs and skin may trigger Alzheimer’s disease. Vaccinations such as Shingrix have been shown to cut dementia risk by about 17 percent, likely by dampening inflammatory pathways. Lifestyle measures—including a Mediterranean...
We Must Close the 'Shocking' Knowledge Gap in Women's Health
Anita Zaidi calls for urgent research to close the knowledge gap in women’s health, highlighting the deadly impact of pregnancy complications like pre‑eclampsia. More than 700 women and 6,500 newborns die daily from these conditions, with the highest toll in...
