Fitting a right hand in a left-handed mitten

Many biomolecules come in two versions that are each other's mirror image, like a left and a right hand. Cells generally use the left-hand version of amino acids to produce proteins, and uptake mechanisms were thought to ...

'Undruggable' Parkinson's molecule spills its secrets

UC San Francisco researchers have for the first time developed a strategy for targeting a key molecule implicated in Parkinson's disease, opening up a potential new treatment strategy for the currently incurable movement ...

Study tracks inner workings of the brain with new biosensor

An international team of scientists have taken an important step towards gaining a better understanding of the brain's inner workings, including the molecular processes that could play a role in neurological disorders.  

Tiny sensors developed to study the secrets of brain chemistry

Nanosensors are incredible information-gathering tools for myriad applications, including molecular targets such as the brain. Neurotransmitter molecules govern brain function through chemistry found deep within the brain, ...

Rays provide power for an electric generator

Scientists from the RIKEN Quantitative Biology Center in Japan removed the electric organ from a torpedo and chemically stimulated the organ by injecting a solution of the neurotransmitter acetylcholine though a syringe. ...
