Entropic effects in cell lineage tree packings

Entropic effects in cell lineage tree packings, Published online: 16 July 2018; doi:10.1038/s41567-018-0202-0

The organization of small clusters of connected cells confined to an egg chamber during early development can be mapped onto a tree packing problem. Entropically preferred packing configurations are shown to arise more readily in experiment.

Measurements in two bases are sufficient for certifying high-dimensional entanglement, Published online: 16 July 2018; doi:10.1038/s41567-018-0203-z

Certification of high-dimensional entanglement is required for improved quantum communication protocols, and is now shown to be achievable in an efficient manner by measuring quantum states twice in two different bases.

Neutrino interferometry for high-precision tests of Lorentz symmetry with IceCube

Neutrino interferometry for high-precision tests of Lorentz symmetry with IceCube, Published online: 16 July 2018; doi:10.1038/s41567-018-0172-2

A violation of Lorentz symmetry would represent a fundamental departure from the physics of the standard model. Searching for anomalous neutrino oscillations, the IceCube collaboration reports no violation, and puts stringent bounds on its existence.

Connected development, Published online: 16 July 2018; doi:10.1038/s41567-018-0236-3

Mapping cell lineages onto a problem in graph theory suggests that physical principles regulate cell positioning during egg development in the fruit fly — providing an elegant example of how physics can advance our understanding of biology.

Superlight inverse Doppler effect

Superlight inverse Doppler effect, Published online: 09 July 2018; doi:10.1038/s41567-018-0209-6

The authors theoretically investigate a novel form of a Doppler effect in homogeneous systems with positive refractive index that occurs under certain conditions. It is suggested that this Doppler effect can be experimentally separated from other Doppler effects by using polaritons such as those found in graphene.

Coexisting first- and second-order electronic phase transitions in a correlated oxide, Published online: 09 July 2018; doi:10.1038/s41567-018-0201-1

A phase transition between metallic and insulating states is observed to simultaneously happen in two ways at once. The bulk of the sample shows an instantaneous jump in the conductivity, while 1D domain walls show a slow switching into a metallic state.

Physical biology of the cancer cell glycocalyx, Published online: 04 July 2018; doi:10.1038/s41567-018-0186-9

It may look like little more than slime, but the glycocalyx coating our cells plays a key role in cell signalling. And changes to its physical structure have been linked to cancer, triggering emergent behaviours that form the focus of this Review.

Biophysics across time and space, Published online: 04 July 2018; doi:10.1038/s41567-018-0206-9

Understanding the behaviour of almost any biological object is a fundamentally multiscale problem — a challenge that biophysicists have been increasingly embracing, building on two centuries of biophysical studies at a variety of length scales.
