Life Expectancy News and Research

RSS

Life expectancy is the expected (in the statistical sense) number of years of life remaining at a given age. It is denoted by e''x'', which means the average number of subsequent years of life for someone now aged ''x'', according to a particular mortality experience.

Global hotspots where breast cancer and atrial fibrillation overlap

Investigating breast cancer and atrial fibrillation overlap, this study highlights key risk factors, underscoring the need for integrated prevention approaches.

Study maps how exercise, sleep, diet, and mood connect in daily life

Researchers followed 79 U.S. adults for 70 days and found that daily lifestyle behaviors clustered with positive and negative affect across same-day, next-day, and between-person patterns. Person-specific networks showed that these daily habits and mood links varied widely, suggesting future lifestyle interventions may need to be more personalized.

Aging immune cells may explain why autoimmunity rises later in life

A new Review reveals how aging can push the immune system into a paradoxical state, weaker against threats yet more prone to attacking the body’s own tissues.

Family genetics study reveals clues to longer healthspan

Understanding why some people stay healthy without developing disease until late in life (have an increased healthspan), whereas others become infirm at a much younger age has important implications for the health of today's ageing population.

Study reveals different factors driving rising neurological disease rates

The growing number of people living with Parkinson's disease (PD), multiple sclerosis (MS) and motor neuron disease (MND) is being driven by different underlying factors, according to new research due to be presented at the European Academy of Neurology (EAN) Congress 2026 and published in Neurology.

Trauma-related conditions drive deaths in women with HIV

Women with HIV most often die from preventable, trauma-related conditions like substance use and mental illness - not the virus itself. Yet, these leading causes are largely missing from official death records, according to new research by UC San Francisco.

Review uses evolutionary lens to examine modern human aging rates

A review article now published in "Nature Reviews Genetics" brings together evolutionary theory, comparative genomics and large-scale human genetics to explain why we age and why aging rates differ among individuals and species.
