The color of hydrangea isn't just genetics — it's the soil they grow in.
Specifically, soil pH affects the availability of aluminum, which in turn influences flower color.
Bacteria may have adapted to oxygen well before Earth’s atmosphere was saturated with it, according to a new study in Science. The findings underscore the dynamic relationship between biological evolution and Earth's geological history.

Our new @NatureAging paper: We built 14 "biological clocks" representing the biological age and rate of aging of 14 major body systems using data from 13,000 people of the Human Phenotype Project
Key findings:
1. Biological clocks are clinically meaningful: People with higher biological age for some body system are at greater risk for disease related to that body system (e.g., higher aging rate of insulin resistance associates with higher risk for diabetes)
2. Surprisingly, biological clocks for different body systems are mostly independent, i.e., a person with a higher rate of aging for one body system does not necessarily have higher aging rates in other body systems
3. Males and females age differently: While males age linearly, females exhibit a sharp non-linear increase between the ages 50-55. This sharp increase is associated with menopause. When comparing pre- and post-menopausal females of the same chronological age, we find that post-menopausal females have higher biological age for several body systems

How do mitochondria, the cell’s energy-producing organelles, perform competing metabolic processes?
Segregation into distinct populations — one that makes energy-storing ATP molecules and one that does not — could explain it

If you are sedentary, you are unhealthy, even if you don’t have a diagnosed health condition.
A new study makes this quite clear.
Researchers compared sedentary adults (no structured exercise) to a group of adults who were moderately active (they exercised at least 150 minutes per week).
Importantly, both groups were “healthy” in that they had no diagnosed cardiometabolic conditions.
But the sedentary adults had worse mitochondrial function, poorer cardiorespiratory fitness, and a lower rate of fat oxidation at rest and during exercise. They also produced more lactate at a *much* lower power output than the moderately-active adults.
These findings have profound implications for how we classify and recruit participants in research studies.
They suggest that the “healthy sedentary” phenotype doesn’t exist—
a lack of disease does not imply someone is in good metabolic health. As such, we shouldn’t be using these “healthy sedentary” people as control subjects in studies.
