First animals oxygenated the ocean, study suggests
The evolution of the first animals may have oxygenated the earth’s oceans – contrary to the traditional view that a rise in oxygen triggered their development.
New research led by the University of Exeter contests the long held belief that oxygenation of the atmosphere and oceans was a pre-requisite for the evolution of complex life forms.

The surface of the earth is covered by a patchwork of river channels. These form the backbone of the landscape, defining boundaries or permitting communication between diverse ecosystems. However, river networks might be much more dynamic than has previously been assumed as demonstrated by researchers at ETH Zurich and MIT in Boston.

The Earth’s outer layer is made up of a series of moving, interacting plates whose motion at the surface generates earthquakes, creates volcanoes and builds mountains. Geoscientists have long sought to understand the plates’ fundamental properties and the mechanisms that cause them to move and drift, and the questions have become the subjects of lively debate.

Scientist Find Unique Protein that Misdirects Immune System
A team led by scientists at The Scripps Research Institute (TSRI) has discovered an unusual bacterial protein that attaches to virtually any antibody and prevents it from binding to its target. Protein M, as it is called, probably helps some bacteria evade the immune response and establish long-term infections.
