Where did the earth's nitrogen come from? Scientists from Rice University show that a primary source of the indispensable building block for life was close to home. The isotopic signatures of nitrogen in iron meteorites indicate that Earth likely collected its nitrogen not only from the region beyond Jupiter's orbit, but also from the dust […]
The HTA has teamed up with the sustainability certification of Planet Mark as the first step in the implementation of its sustainability roadmap.
Scientists claim to have found the "missing link" in the process that led to an ice age on Earth. The melting of icebergs in Antarctica is key, according to the Cardiff University team, triggering a series of chain reactions that plunge the earth into prolonged periods of cold temperatures. The results were published in today […]
Loss of biodiversity and accelerating climate change in the coming decades, coupled with ignorance and inaction, threaten the survival of all species, including our own, according to experts from institutions such as Stanford University, UCLA and Flinders University.
