Molecular Oncology, EarlyView.Breast cancer remains a major cause of cancer death in women, frequently developing endocrine therapy resistance. This study demonstrates that upregulated p21‐activated kinase 1 (PAK1) activity drives resistance to tamoxifen and long‐term estrogen deprivation in ER+ breast cancer models.

New Journal of PhysicsWe propose an experimental setup for manipulating the spontaneous emission (SE) of quantum scatterers, based on a spatial light modulator. We discuss this idea in the case of trapped barium ions as quantum emitters.

Trapped-Mg+ Apparatus for Control and Structure Studies [PDF]
, 2006 Trapped ions can be isolated from external perturbations such as collisions with other atoms or electric and magnetic field inhomogeneities. For this reason, trapped ions can be useful in spectral measurements, quantum information technology and ...

FEBS Open Bio, EarlyView.Despite frogs avoiding low temperatures, examination of four salamander species revealed that none avoided cold and all possessed cold tolerance. Functional analysis of TRPM8, a cold sensor, showed that all salamander TRPM8s had lost their cold sensitivity.

The Mechanism of Trapped Ions Eroding the Electrochromic Performances of WO3 Thin Films
International Journal of Electrochemical Science, 2018 The electrochromic WO3 devices normally suffer from the degradation of long-term performances since the accumulation of trapped ions in the host structure.

Space-time crystals of trapped ions
, 2012 Spontaneous symmetry breaking can lead to the formation of time crystals, as well as spatial crystals. Here we propose a space-time crystal of trapped ions and a method to realize it experimentally by confining ions in a ring-shaped trapping potential ...

Evolutionarily divergent DUF4465 domains have a common vitamin B12‐binding function
FEBS Open Bio, EarlyView.We show that DUF4465 family proteins, widespread across bacteria from gut microbiomes, hydrothermal vents, and soil, share a common vitamin B12‐binding function. These augmented β‐jellyroll proteins bind vitamin B12 via extended loops. Our findings establish sequence‐diverse DUF4465 proteins as a widespread class of B12‐binding proteins, highlighting ...

Scalable imaging of trapped ions
, 2011 Wavelength scale imaging of trapped Ytterbium ions was demonstrated using a microfabricated phase Fresnel lens. Near diffraction-limited spot sizes of below 440 nm (FWHM) were achieved, an important precursor to efficient single-mode coupling.Full ...

Energy transport in trapped ion chains
New Journal of Physics, 2014 We experimentally study energy transport in chains of trapped ions. We use a pulsed excitation scheme to rapidly add energy to the local motional mode of one of the ions in the chain.
