XPRIZE Healthspan Finals

XPRIZE Healthspan Finals: The Latest in the Race to Extend Healthy Aging

Imagine reaching your 70s or 80s with the strength to keep moving, the clarity to stay engaged, and the independence to continue living life on your own terms. For too many people, the later decades of life are marked not by vitality, but by impaired muscle function, cognition, and immune function.

But what if we could change what it means to grow old? As populations age and age-related conditions continue to rise worldwide, improving healthspan has become one of the defining scientific and public health challenges of our time. It’s a challenge the $101 million XPRIZE Healthspan competition was created to address. As XPRIZE announces the 20 finalist teams advancing to the next stage of the competition, we’ll look at what XPRIZE means to the global race to transform how we age – and, more importantly, what the competition has decided to measure.

Exploring Longevity’s Next Frontier Senolytics and Zombie Cells

Exploring Longevity’s Next Frontier: Senolytics and Zombie Cells

They’re commonly known as “zombie cells,” but senescent cells are no work of fiction. Discovered in the early 1960s by Leonard Hayflick and Paul Moorhead, senescent cells are cells that remain metabolically active despite being damaged or stressed to the point that they permanently stop dividing. Unlike healthy cells, senescent cells no longer function normally and cannot continue the process of replication. Instead, they linger in tissues throughout the body, secreting a mix of inflammatory molecules known as the senescence-associated secretory phenotype (SASP).

Initially, cellular senescence serves an important protective role, helping prevent damaged cells from becoming cancerous and supporting processes such as wound healing. However, the accumulation of senescent cells over time can become harmful, especially as natural clearance mechanisms, including immune system activity, decline with age. Senescent cells and SASP contribute to tissue damage, promote senescence in neighboring cells, and are increasingly associated with chronic inflammation and age-related diseases.

But researchers are exploring whether senolytics may offer a way to address this process.

Longevity Preparedness: A New Metric for a Longer-Living Population

Longevity Preparedness: A New Metric for a Longer-Living Population

Longevity is no longer a theoretical concept. It has become a reality, one that is reshaping healthcare systems, financial planning, and societal expectations. But longevity alone does not guarantee preparedness for the years that it adds. So, the question becomes: how ready are we, really?

As global life expectancy continues to rise, we are slowly learning that other systems are not necessarily keeping pace with this shift. Factors such as finances, health status, housing, care planning, and behavioral readiness are not advancing at the same rate as lifespan extension. Instead, they seem to be fragmented and underdeveloped.
