Microscopic Devices That Control Vibrations Could Allow Smaller Mobile Devices
Researchers take step forward with phononics, for ultrasound-based information processing News Writer: Emily Velasco A phononic device next to a dime for scaleCredit: Caltech To make modern communications possible, today's mobile devices make use of components that use acoustic waves (vibrations) to filter or delay signals. However, current solutions have limited functionalities that prevent further miniaturization of the mobile devices and constrain the available communication bandwidth.
Animals and the zoogeochemistry of the carbon cycle
Predicting and managing the global carbon cycle requires scientific understanding of ecosystem processes that control carbon uptake and storage. It is generally assumed that carbon cycling is sufficiently characterized in terms of uptake and exchange between ecosystem plant and soil pools and the atmosphere. We show that animals also play an important role by mediating carbon exchange between ecosystems and the atmosphere, at times turning ecosystem carbon sources into sinks, or vice versa.
Another El Niño on the horizon?
The jury is still out as to whether climate change will lead to stronger El Niño events, but while representatives from around 200 countries at the COP24 conference are working to breathe life into the 2105 Paris Agreement, there is a 75–80% chance that a fully-fledged event could be with us in the next couple of months.
