Eating food rich in protein can boost cardiovascular health as much as exercise or quitting smoking

protein2

The results of a new UEA study reveal that people who eat high levels of certain amino acids found in meat and plant-based protein have lower blood pressure and show less arterial stiffness, directly translating to higher levels of cardiovascular health. The magnitude of the association is similar to those previously reported for lifestyle risk factors including salt intake, physical activity, alcohol consumption and smoking.

In 2011 the Queller-Strassmann lab, then at Rice University, made a surprising announcement in Nature Letters.
They had been collecting single-celled amoebae of the species Dictyostelium discoideum from the soil in Virginia and Minnesota. While laboratory grown strain of Dicty happily fed on the bacteria provided for it by its keepers, roughly one third of the wild strains showed a green (or maybe bacterial) thumb. When food was short, they gathered up bacteria, carried them to new sites and seeded the soil with them.

The fact that the greatest biodiversity of large mammals we know of today is recorded in Africa is a legacy of past human activity, not climate or environmental phenomena, new study reveals. The paper theorizes at how the world today would look if Homo sapiens had never existed.
In a previous analysis, the researchers from Aarhus Univeristy, Denmark, they showed how the mass extinction of large mammals during the last Ice Age and the subsequent millennia, most notably the late-Quaternary megafauna extinction, is largely explainable by the expansion of modern humans across the world.

This is a guest post by Kristin Drexler, faculty member, Human Ecology and Forestry, School of Science, technology, Engineering, and Math at American Public University. The active participation of local communities is a critical component to the conservation of protected areas like national parks and preserves. Ironically, while these areas are most often thought of in a national and international
