Bubble-recoil could be used to cool microchips, even in space

more »
The bubbles that form on a heated surface create a tiny recoil when they leave it, like the kick from a gun firing blanks. Now researchers have shown how this miniscule force can be harnessed to mix liquid coolant around high-power microelectronics -- in space or on Earth.

Paleolake deposits on Mars might look like sediments in Indonesia

more »
A new article details the clay mineralogy of sediment from Lake Towuti, Indonesia, using a technique called visible to near-infrared (VNIR) spectroscopy. VNIR measures the signature of reflected light from a sample across a larger wavelength range than just visible light. At Lake Towuti, the spectral record shows distinct variations in clay mineralogy over the past 40,000 years.

Space energy technology restored to make power stations more efficient

more »
Satellite-powering technology that was abandoned decades ago has been reinvented to potentially work with traditional power stations to help them convert heat to electricity more efficiently, meaning we would need less fossil fuel to burn for power. A new study presents a prototype energy converter, which uses graphene instead of metal, making it almost seven times more efficient.
