Study provides insight on how DNA code is turned into instructions for protein construction

A team of scientists from the Hebrew University of Jerusalem and the Weizmann Institute of Science has revealed the structure of a cellular editor that “cuts and pastes” the first draft of RNA straight after it is formed from its DNA template.

Researchers map structure of anti-cancer molecule and open the door to the creation of more effective cancer treatments

Scientists at Emory University, in collaboration with researchers at three national laboratories, have solved the structural puzzle of how an emerging class of promising cancer drugs works to halt cell division. The discovery potentially opens the door to the creation of more effective cancer treatments.

A prototype microscope that uses neutrons instead of light to "see" magnified images

A prototype microscope that uses neutrons instead of light to "see" magnified images has been demonstrated at the National Institute of Standards and Technology. Neutron microscopes might eventually offer certain advantages over optical, X-ray and electron imaging techniques such as better contrast for biological samples.
