Innovative process produces biodegradable cellulose-based films

Purdue University researchers have developed tough, flexible, biodegradable films from cellulose, the main component of plant cell walls. The films could be used for products such as food packaging, agricultural groundcovers, ...

A calcium pump caught in the act

Researchers at Aarhus University have described one of the cell's key enzymes, the calcium pump, in its decisive moment—a so-called transition state. These findings provide a very detailed picture of how one of the most ...

Scientists discover blueprint of body's heat sensor

Touch a hot stove, and your fingers will recoil in pain because your skin carries tiny temperature sensors that detect heat and send a message to your brain saying, "Ouch! That's hot! Let go!"

How plant cell compartments 'chat' with each other

A team of researchers led by scientists from the University of Bonn has discovered a basis of communication in plant cells: The "MICU" protein controls the calcium ion concentration in the cellular power stations. Using these ...

Biochemists uncover structure of cellular memory mechanism

Calcium is a crucial element in the body that controls thought, movement and other bodily functions. These events are directed by specialized proteins called ion channels that allow the flow of calcium ions in and out of ...
