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 ...

New software brings lower-resolution cryo-EM maps into focus

Cryo-electron microscopy is now the most popular method for determining protein structures, which helps researchers develop drugs for different kinds of ailments. Over the last several decades, it has replaced X-ray crystallography ...

Sophisticated molecular machines in action

Almost all living organisms from bacteria to humans have gate-like protein complexes in their cell membranes that get rid of unwanted or life-threatening molecules. This is not always advantageous, since in the case of bacteria ...

Neutrons get a wider angle on DNA and RNA to advance 3-D models

Scientists from the National Institute of Standards and Technology (NIST) and the University of Maryland are using neutrons at Oak Ridge National Laboratory (ORNL) to capture new information about DNA and RNA molecules and ...

'Fishing a line' coupled with clockwork for daily rhythm

Organisms on this planet, including human beings, exhibit a biological rhythm that repeats about every 24 hours to adapt to the daily environmental alteration caused by the rotation of the earth. This circadian rhythm is ...
