Highly sensitive dopamine detector uses 2-D materials

A supersensitive dopamine detector can help in the early diagnosis of several disorders that result in too much or too little dopamine, according to a group led by Penn State and including Rensselaer Polytechnic Institute ...

New class of enzymes could lead to bespoke diets, therapeutics

Everyone seems to have an opinion about which foods to eat or avoid, how to lose weight (and keep it off!), and which superfood to horde. But there's a better place to search for health secrets than in a tropical berry: the ...

Designing and repurposing cell receptors

EPFL scientists have developed a computational method modeling and designing protein allostery that allows the accurate and rational engineering and even repurposing of cell receptors. The method can be a significant tool ...

Human medicines affect fish behavior

Human medicines that act on important signal systems in the brain make fish bolder, shows a new study on three-spined sticklebacks by researchers at Linköping University. The results reinforce that the signal substances ...

Learning from experience is all in the timing

As animals explore their environment, they learn to master it. By discovering what sounds tend to precede predatorial attack, for example, or what smells predict dinner, they develop a kind of biological clairvoyance—a ...

New quantum material could warn of neurological disease

What if the brain could detect its own disease? Researchers have been trying to create a material that "thinks" like the brain does, which would be more sensitive to early signs of neurological diseases such as Parkinson's.
