Every year, falls lead to hospitalization or death for hundreds of thousands of elderly Americans. Standard clinical techniques generally cannot diagnose balance impairments before they lead to falls. But researchers have found evidence that virtual reality (VR) could be a big help – not only for detecting balance impairments early, but perhaps also for reversing those impairments and preventing falls.
Earth science or geoscience is an all-embracing term for the fields of science related to the planet Earth. It can be considered to be a branch of planetary science, but with a much older history. There are both reductionist and holistic approaches to Earth sciences. The Earth sciences can include the study of geology, the lithosphere, and the large-scale structure of the Earth’s interior, as well as the atmosphere, hydrosphere, and biosphere. Typically, Earth scientists use tools from geography, physics, chemistry, biology, chronology, and mathematics to build a quantitative understanding of how the Earth system works and evolves.
