New maps reveal true extent of human footprint on Earth
As global populations swell, farmers are cultivating more and more land in a desperate bid to keep pace with the ever-intensifying needs of humans. As a result, agricultural activity now dominates more than a third of the Earth's landscape and has emerged as one of the central forces of global environmental change, say scientists at the Center for Sustainability and the Global Environment...Alleged 40,000-year-old human footprints in Mexico much, much older than thought
Alleged footprints of early Americans found in volcanic rock in Mexico are either extremely old - more than 1 million years older than other evidence of human presence in the Western Hemisphere - or not footprints at all, according to a new analysis published this week in Nature. The study was conducted by geologists at the Berkeley Geochronology Center and the University of California, Be...Human's ecological footprint in 2015 and Amazonia revealed
A recent study shows human population size and affluence are the main drivers of human-caused environmental stressors, while urbanization, economic structure and age of population have little effect. Modeling global average productivity to compare environmental tradeoffs and human-induced stressors in the environment Thomas Dietz (Michigan State University), Eugene Rosa (Washington State U...Stackable Cage with large footprint
Description:The Stackable Cage System provides anterior column support for single or multilevel corpectomies or total vertebrectomies from T1 to L5. The system consists of one or more Peek Carbon Fiber Polymer cages that are stacked to a desired height, accommodating various patient needs. The Peek Carbon Fiber Reinforced Polymer material emulates the biomechanical properties of human cortical bone, optimizi...Stackable Cage with medium footprint
