New Biomarkers can help ID a person’s risk of getting cardiac disease with greater precision than traditional risk factors alone. When you visit your GP you can get your blood analyzed for cholesterol and triglycerides, to get an idea of your risk for cardiovascular disease. With additional information about BMI, smoking habits and blood pressure, this can be used to calculate your 10-yr risk for cardiovascular disease. However, the use of risk prediction calculators has declined in the primary care setting because the currently available calculators only explain a modest proportion of the incidence...

Aerobic exercise can help alleviate excessive daytime sleepiness among depressed individuals. Researchers looking at blood samples identified two biological markers for the condition, called hypersomnia, which is characterized by sleeping too much at night as well as excessive daytime sleepiness, in those with Major Depressive Disorder.
“Hypersomnia, as well as insomnia, have been linked in the development, treatment, and recurrence of depression. Sleep disturbances are also some of the most persistent symptoms in depression...

The scientists studied these biosignatures with the help of polarization filters: If biopigments were present as a sign of life on a planet, they would leave behind a detectable polarized signature in the reflected light.
Eg Chlorophyll pigments in plant leaves, absorb blue to red light but reflect a small part of green in the visible spectrum and thus appear green...
