Leicester study of data captured in orbit around Jupiter has revealed new insights into what’s happening deep beneath the gas giant’s distinctive and colourful bands.

Data from the microwave radiometer carried by NASA’s Juno spacecraft shows that Jupiter’s banded pattern extends deep below the clouds, and that the appearance of Jupiter’s belts and zones inverts near the base of the water clouds. Microwave light allows planetary scientists to gaze deep beneath Jupiter’s colourful clouds, to understand the weather and climate in the warmer, darker, deeper layers.

At altitudes shallower than...

Sweet! How Glycogen is linked to Heat Generation in Fat Cells

Researchers describe how energy expenditure and heat production are regulated in obesity through a previously unknown cellular pathway. Humans carry around with them, often abundantly so, at least two kinds of fat tissue: white and brown. White fat cells are essentially inert containers for energy stored in the form of a single large, oily droplet. Brown fat cells are more complex, containing multiple, smaller droplets intermixed with dark-colored mitochondria — cellular organelles that give them their color and are the “engines” that convert the lipid droplets into heat and energy.

Some people also have “beige”...

Making the Strange Metal State in High Temperature Superconductors even Stranger

Researchers from Chalmers University of Technology, Sweden, have uncovered a striking new behavior of the ‘strange metal’ state of high temperature superconductors. The discovery represents an important piece of the puzzle for understanding these materials, and the findings have been published in the journal Science.

Superconductivity, where an electric current is transported without any losses, holds enormous potential for green technologies. For example, if it could be made to work at high enough temperatures, it could allow for lossless transport of renewable energy over great distances. Investigating this phenomenon is the aim of the research field of high temperature superconductivity...

New study outlines biotechnology process to produce rocket fuel on red planet. Researchers at the Georgia Institute of Technology have developed a concept that would make Martian rocket fuel, on Mars, that could be used to launch future astronauts back to Earth.

The bioproduction process would use three resources native to the red planet: carbon dioxide, sunlight, and frozen water. It would also include transporting two microbes to Mars. The first would be cyanobacteria (algae), which would take CO2 from the Martian atmosphere and use sunlight to create sugars...
