Device for harnessing terahertz radiation might enable self-powering implants, cellphones, other portable electronics.
A microbial organism pulls electricity from water in the air.
- Hidden in the mud along the banks of Washington D.C.'s Potomac River may be a profound new source of electricity.
- The microbe makes nanowires that produce a charge from water vapor in ordinary air.
- Already capable of powering small electronics, it appears that larger-scale power generation is within reach.

A new device shows promising results in its ability to convert CO2 and water into useful fuels.
- Artificial photosynthesis devices have long been touted as a way to remove carbon dioxide from the atmosphere and turn it into useful products.
- New research describes a highly efficient and cheap device that could be used to turn waste carbon dioxide into methane.
- Natural gas, which mainly consists of methane, is a cleaner fuel than coal and has been characterized as a "bridge fuel" prior to transitioning to renewable energy sources, but not everyone thinks it's a good idea to burn yet more hydrocarbons.
You've likely heard of solar energy, but what is osmotic energy?
- Osmotic power plants harvest energy from the difference in pressure or salinity between salt and freshwater using a semi-permeable membrane.
- One of the major challenges for this kind of renewable energy, however, has been developing effective and durable membranes.
- Now, new research demonstrates a durable and effective membrane that could significantly improve osmotic energy collection.
