Elite performance takes natural ability coupled with elite levels of training. That last part has an effect later in life, according to a new analysis. It found that one in four retired Olympians have some level of osteoarthritis, which causes changes in the joint and can lead to discomfort, pain and disability.

A clinical trial where dogs get advanced cancer treatment could pave the way for a new immunotherapy treatment in kids. 

Sarcoma is a cancer of the bones and soft tissues and one of the most common childhood cancers, the third most common cancer in children, with one in three dying from their disease. The first step for almost all sarcoma patients after diagnosis is surgery to remove the tumor. 

A new study says early intervention with cryoballoon catheter ablation (cryoablation) can halt disease progression and reduce risk of serious health impacts of atrial fibrillation(AF).

Age is relative. If you put two people the same chronological age next to each other, one may look younger while one may nonetheless be biologically younger. Yet age is the biggest risk factor for most diseases even though it doesn't tell much of a health story.

Population statistics about age are as pointless in individual care as most epidemiology, but they can provide proxies for biological aging that at least have people taking important things for their future, rather than placebos like a USDA food servings chart.

One of the largest mass extinctions ever is bad. Six marine extinctions is even worse. That all happened in one period now known as The Devonian Period, 419 to 358 million years ago.

Yet that is also when the world got the trees and complex land plants similar to those we know today first evolving and spreading across the landscape. Those complex root systems affected soil biogeochemistry and set off part of the chain that allowed humans to thrive.

In 2022, the United States surpassed one million COVID-19 related deaths. Many of them had co-morbidities that are risk factors for many diseases, like old age, cancer, or respiratory issues.

Added into those risk factors were lifestyle diseases like obesity, type 2 diabetes, and smoking, all of which are linked to poorer outcomes from COVID-19 infections. Those have all long been linked to negative health outcomes, which is why we have advocated for exercise, sensible diets, and giving up cigarettes as first lines of defense against many future problems.
