Hyperfine structure of the hydroxyl free radical (OH) in electric and magnetic fields
New Journal of Physics, 2015 We investigate single-particle energy spectra of the hydroxyl free radical (OH) in the lowest electronic and rovibrational level under combined static electric and magnetic fields, as an example of heteronuclear polar diatomic molecules.

An isoform of 14‐3‐3 protein regulates transbilayer lipid movement at the plasma membrane
FEBS Letters, EarlyView.Loss of 14‐3‐3ζ in CHO cells confers resistance to exogenous phosphatidylserine (PS) and impairs endocytosis‐independent inward flip‐flop of fluorescent PS at the plasma membrane. RNAi‐mediated knockdown reproduces this defect, while no additive effect is seen in ATP11C‐deficient cells.

Effect of nuclear spin symmetry in cold and ultracold reactions: D + para/ortho-H2
New Journal of Physics, 2015 We report results for reaction and vibrational quenching of the collision D with para-H _2 ( $v,j=0$ ) and ortho-H _2 ( $v,j=1$ ) at cold and ultracold temperatures.

From mice to humans—divergent strategies for intestinal homeostasis and regeneration
FEBS Letters, EarlyView.Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Laser cooling Rydberg molecules—a detailed study of the helium dimer
New Journal of PhysicsThe helium dimer in its metastable triplet state is a promising candidate to be the first laser-cooled homonuclear molecule. An ultracold gas of He $_2^*$ would enable a new generation of precision measurements to test quantum electrodynamics for three ...

A Zeeman slower for diatomic molecules
New Journal of Physics, 2018 We present a novel slowing scheme for beams of laser-coolable diatomic molecules reminiscent of Zeeman slowing of atomic beams. The scheme results in efficient compression of the one-dimensional velocity distribution to velocities trappable by magnetic ...

FEBS Letters, EarlyView.Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.

Isotopologue-selective laser cooling of molecules
New Journal of PhysicsDirect laser cooling of molecules has made significant progress in recent years. However, the selective cooling and manipulation of generic molecular samples based on their isotopic composition, which is ubiquitous in atomic laser cooling, has not yet ...

Magneto-optical trapping forces for atoms and molecules with complex level structures
New Journal of Physics, 2015 Laser cooling and magneto-optical trapping of molecules typically involves multiple transitions driven by several laser frequencies. We analyze how magneto-optical trapping forces depend on the angular momenta, F _l and F _u , and the g -factors, g _l ...
