A team of climate geochemists at the Max Planck Institute for Chemistry, University of the Witwatersrand and Princeton University has found evidence that early hominins living in South Africa ate a mostly vegetarian diet. ...
Mars's atmosphere and climate are impacted by interactions with solar wind, a stream of plasma comprised of protons and electrons that flows from the sun's outermost atmosphere (corona), traveling at speeds of 400–1,000 ...
Mars has northern and southern hemispheres like Earth, but their defining characteristics are markedly different, a phenomenon known as Martian dichotomy. The Southern Highlands are older, higher in elevation and more cratered ...
Observing the effects of special relativity doesn't necessarily require objects moving at a significant fraction of the speed of light. In fact, length contraction in special relativity explains how electromagnets work. A ...
Using the Cerro Tololo Inter-American Observatory (CTIO), an international team of astronomers have performed deep optical observations of a dwarf galaxy known as NGC 300. As a result, they detected a stellar stream, shells ...
The Little Ice Age was a period of significant cooling from the early 14th to mid-19th centuries, which saw mean temperatures across the northern hemisphere drop by up to 2°C and the advancement of glaciers.
An international team of chemists has successfully created methylenedistibiranes, which are three-membered rings that have two antimony atoms and one carbon atom. In their paper published in the Journal of the American Chemical ...
An international team of environmentalists, zoologists and land use specialists has developed an extinction probability metric for land that is converted to agriculture. Their paper is published in the journal Philosophical ...
