They found surprisingly, that human-induced emissions of methane and nitrous oxide from ecosystems overwhelmingly surpass the ability of the land to soak up carbon dioxide emissions, which makes the terrestrial biosphere a contributor to climate change. |
Protected Majorana states for quantum information Posted: 09 Mar 2016 10:56 AM PST Quantum technology has the potential to revolutionize computation, cryptography, and simulation of quantum systems. However, quantum states are fragile, and so must be controlled without being measured. Researchers have now demonstrated a key property of Majorana zero modes that protects them from decoherence. The result lends positive support to the existence of Majorana modes, and goes further by showing that they are protected, as predicted theoretically. |
Posted: 09 Mar 2016 10:56 AM PST According to a new study, our ancestors between 2 and 3 million years ago started to spend far less time and effort chewing by adding meat to their diet and by using stone tools to process their food.
