Novel electron microscopy offers nanoscale, damage-free isotope tracking in amino acids

DOE/Oak Ridge National Laboratory
Peer-Reviewed Publication

A new electron microscopy technique that detects the subtle changes in the weight of proteins at the nanoscale -- while keeping the sample intact -- could open a new pathway for deeper, more comprehensive studies of the basic building blocks of life. Scientists at Oak Ridge National Laboratory described in the journal Science the first use of an electron microscope to directly identify isotopes in amino acids at the nanoscale without damaging the samples.

Precision experiment first to isolate, measure weak force between protons, neutrons

DOE/Oak Ridge National Laboratory
Peer-Reviewed Publication

A team of scientists has for the first time measured the elusive weak interaction between protons and neutrons in the nucleus of an atom. They had chosen the simplest nucleus consisting of one neutron and one proton for the study. Through a unique neutron experiment at Oak Ridge National Laboratory, experimental physicists resolved the weak force between the particles at the atom's core, predicted in the Standard Model that describes the elementary particles and their interactions.

Neutron micelle measurements lend insights into improved drug delivery

DOE/Oak Ridge National Laboratory

Researchers from the University of Houston are using neutron scattering at ORNL to research how unique biological structures known as micelles can make drugs more effective. Micelles can form around drug molecules in order to transport them through the human body. To make micelles better at transporting these molecules, the researchers are investigating how micelles are affected by the molecules they transport.
