Landscape cultivation alters δ30Si signature in terrestrial ecosystems
Despite increasing recognition of the relevance of biological cycling for Si cycling in ecosystems and for Si export from soils to fluvial systems, effects of human cultivation on the Si cycle are still relatively understudied. Here we examined stable Si isotope (δ(30)Si) signatures in soil water samples across a temperate land use gradient. We show that - independent of geological and climatol...
متن کاملOldest Pathology in a Tetrapod Bone Illuminates the Origin of Terrestrial Vertebrates
The origin of terrestrial tetrapods was a key event in vertebrate evolution, yet how and when it occurred remains obscure, due to scarce fossil evidence. Here, we show that the study of palaeopathologies, such as broken and healed bones, can help elucidate poorly understood behavioural transitions such as this. Using high-resolution finite element analysis, we demonstrate that the oldest known ...
متن کاملTuberculosis & traditional medicine: fighting the oldest infectious disease, using the oldest source of medicine
It is believed that tuberculosis has been killing human beings for over 4000 years. Several reports exist of ancient Egyptian mummies having signs of tubercular decay in their bodies. After the discovery of powerful anti-TB drugs such as streptomycin, isoniazid and rifampin during 1940-70s, it was thought that TB would be gone from the face of the earth, but tuberculosis still remains one of th...

متن کاملTuberculosis and Traditional Medicine: Fighting the Oldest Infectious Disease Using the Oldest Source of Medicines
Tuberculosis (TB) is the oldest documented infectious disease. Fragments of the spinal column from Egyptian mummies from 2400 B.C. shows definite pathological signs of tubercular decay. The term phthisis (consumption) appears first in Greek literature. Hypocrates identified phthisis as the most widespread disease of the times around 460 B.C. Exact pathological and anatomical descriptions of the...
