Dogs can smell when we're stressed, study suggests

The physiological processes associated with an acute psychological stress response produce changes in human breath and sweat that dogs can detect with an accuracy of 93.75%, according to a new study published this week in ...

Hyaluronic acid research could spur new therapeutics

For more than two decades, scientists have puzzled over how vertebrates make the essential polysaccharide hyaluronic acid, which has broad medical applications. One team took a different tack and solved the mystery.

New advances in protein-folding process thermodynamics

In biophysics, the kinetic states of molecules play a determining role in the metabolic and physiological processes in which they take part. Now, a paper published in the journal Proceedings of the National Academy of Sciences ...

The 'airbag' that protects cells against stress

Scientists at the Centro Nacional de Investigaciones Cardiovasculares (CNIC) have identified the molecular mechanisms that allow cells to survive mechanical stress. The results, published today in Nature Communications, show ...
