'Nature's antifreeze' provides formula for more durable concrete

Secrets to cementing the sustainability of our future infrastructure may come from nature, such as proteins that keep plants and animals from freezing in extremely cold conditions. CU Boulder researchers have discovered that ...

An improved method for protein crystal structure visualization

X-ray crystal structure visualization technique has been known for over a hundred years. While it keeps improving, it is extremely difficult to focus rays on objects that are invisible to the naked eye, such as proteins. ...

Engineered protein crystals make cells magnetic

If scientists could give living cells magnetic properties, they could perhaps manipulate cellular activities with external magnetic fields. But previous attempts to magnetize cells by producing iron-containing proteins inside ...

New sample holder for protein crystallography

Proteins are huge molecules that often have complex three-dimensional structure and morphology that can include side chains, folds, and twists. This three-dimensional shape is often the determining factor of their function ...

New structure for human flu virus protein

Researchers from Oxford University have worked out the molecular structure of a protein that is vital for survival of the flu virus. Recently published in Nature, they used several different techniques to look at the arrangement ...

Designer proteins form wires and lattices on mineral surface

The goal of the research, published July 11 in the journal Nature, was to engineer artificial proteins to self-assemble on a crystal surface by creating an exact match between the pattern of amino acids in the protein and ...

How antifreeze proteins make ice crystals grow

Bacteria, plants, insects and fish use antifreeze proteins to protect themselves from the cold. The proteins block the growth of ice crystals. In a new study, a German-Israeli research team has confirmed that these proteins ...
