Raw protein from the top down
Mass spectrometry is a powerful technique for analysing proteins, yet linking higher-order protein structure to amino acid sequence and post-translational modifications is far from simple. Now, a native top-down method has been developed that can provide information on higher-order protein structure and different proteoforms at the same time.

Changing chemistry by degrees
It is easy to overlook just how important temperature is when it comes to chemistry and Michelle Francl wonders if thermometers had a role in turning alchemists into chemists.

Interfering with interference
Molecules can transfer charge between electron donors and acceptors, and can also transport charge when connected between metallic electrodes. These processes are assumed to show generally similar trends, however, a significant departure from this has now been observed in a series of biphenyl bridges.

Meteoric calcium
Calcium is found throughout the solar system, the Earth's crust and oceans, and is an essential constituent of cells, shells and bones — yet it is curiously scarce in the upper atmosphere. John Plane ponders on this 25-year-old mystery.

Control and imaging of O(1D2) precession
Larmor precession of a quantum mechanical angular momentum vector about an applied magnetic field forms the basis for NMR spectroscopy, MRI and a range of other important analytical techniques. This precessional motion has now been imaged for the first time, using velocity-map imaging in a model system of strongly polarized oxygen atoms.

Chemistry from photons
The use of conventional computers to calculate molecular properties is hindered by the exponential increase in computational cost on increasing the size of the molecules studied. Using quantum computers could be the solution and the initial steps are now being taken.

Welcome copernicium?
In the search for superheavy elements, element 112 was a stepping stone towards the 'islands of stability'. Sigurd Hofmann now relates the steps that led to its 'creation' and detection.

Unearthing the unconventional
Quantum tunnelling can at times be the cause of kinetic isotope effects, and in these cases conventional wisdom has been that molecules with isotopes of larger mass will react more slowly. New calculations, however, predict that sometimes the reverse should be true.

Towards quantum chemistry on a quantum computer
Precise calculations of molecular properties from first-principles set great problems for large systems because their conventional computational cost increases exponentially with size. Quantum computing offers an alternative, and here the H2 potential energy curve is calculated using the latest photonic quantum computer technology.
