A simple recipe for MRI contrasts up to four times higher

Magnetic resonance imaging (MRI) makes internal body structures visible. However, before humans or animals are put into the "tube," they are injected with a contrast agent to make visibility possible in the first place.

Air-stability of sodium-based layered-oxide cathode materials

Sodium ion batteries are considered to be one of the most promising alternative systems to lithium-ion batteries, especially for large scale applications. Sodium-based transition-metal oxides with layered structure have been ...

A more concise way to synthesize tetrodotoxin

A small international team of researchers has developed a way to synthesize tetrodotoxin (TTX) using far fewer steps than prior methods. In their paper published in the journal Science, the group describes their process and ...

Chemists unlock secrets of molten salts

A chemist at the University of Cincinnati has come up with a novel way to study the thermodynamic properties of molten salts, which are used in many nuclear and solar energy applications.

VY Canis Majoris is dying, and astronomers are watching

Three-dimensional models of astronomical objects can be ridiculously complex. They can range from black holes that light doesn't even escape to the literal size of the universe and everything in between. But not every object ...

Modeling electrolyte transport in water-rich exoplanets

Oceans on water-rich exoplanets may be enriched with electrolytes, including salts such as sodium chloride, suggests a modeling study published in Nature Communications. The research proposes electrolytes can be transported ...

How electric fish were able to evolve electric organs

Electric organs help electric fish, such as the electric eel, do all sorts of amazing things: They send and receive signals that are akin to bird songs, helping them to recognize other electric fish by species, sex and even ...
