EDITORS' SUGGESTION

Results from a Search for Dark Matter in the Complete LUX Exposure

D. S. Akerib et al. (LUX Collaboration)

Phys. Rev. Lett. 118, 021303 (2017) - Published 11 January, 2017

No dark matter particles have been observed by two of the world’s most sensitive direct-detection experiments, casting doubt on a favored dark matter model.

Phys. Rev. Lett. 118, 023002 (2017) - Published 10 January, 2017

A long-standing discrepancy between experiments and theory concerning the electronic properties of gold has now been resolved.

Spectrum of Wind Power Fluctuations

M. M. Bandi

Phys. Rev. Lett. 118, 028301 (2017) - Published 13 January, 2017

A turbulence-based model of wind variations explains observed fluctuations in the power output from wind turbines.

EDITORS' SUGGESTION

Dark Energy from Violation of Energy Conservation

Thibaut Josset, Alejandro Perez, and Daniel Sudarsky

Phys. Rev. Lett. 118, 021102 (2017) - Published 11 January, 2017

A theoretical analysis suggests that quantum mechanical violations of energy conservation may arise in some proposed models of quantum gravity. If realized in nature, these violations could manifest on cosmological scales as an effective cosmological constant.

EDITORS' SUGGESTION

Observation of $J / ψ ϕ$ Structures Consistent with Exotic States from Amplitude Analysis of $B^{+} \to J / ψ ϕ K^{+}$ Decays

R. Aaij et al. (LHCb Collaboration)

Phys. Rev. Lett. 118, 022003 (2017) - Published 11 January, 2017

The LHCb collaboration has identified four new structures in $B^{+}$ decays that are likely to be tetraquark states. These tetraquark systems contain neither of the light $u$ and $d$ quarks.

EDITORS' SUGGESTION

Channeling of Branched Flow in Weakly Scattering Anisotropic Media

Henri Degueldre, Jakob J. Metzger, Erik Schultheis, and Ragnar Fleischmann

Phys. Rev. Lett. 118, 024301 (2017) - Published 9 January, 2017

A theoretical analysis of wave propagation through anisotropic media shows unexpected collective effects occur.

EDITORS' SUGGESTION

Two-Photon X-Ray Diffraction

J. Stöhr

Phys. Rev. Lett. 118, 024801 (2017) - Published 11 January, 2017

Conventional diffraction theory is predicted to break down for x-rays when spontaneous scattering is replaced by stimulated scattering by a thin film source. The stimulated diffraction pattern generated by the cooperative interaction of two coherent, unentangled photons results in self-focussing beyond the diffraction limit.

EDITORS' SUGGESTION

Quasiphase Transition in a Single File of Water Molecules Encapsulated in (6,5) Carbon Nanotubes Observed by Temperature-Dependent Photoluminescence Spectroscopy

Xuedan Ma, Sofie Cambré, Wim Wenseleers, Stephen K. Doorn, and Han Htoon

Phys. Rev. Lett. 118, 027402 (2017) - Published 12 January, 2017

A temperature induced phase transition occurs in water molecules packed single-file inside a carbon nanotube, as shown by photoluminescence measurements and first-principles calculations.

EDITORS' SUGGESTION

Biochemical Machines for the Interconversion of Mutual Information and Work

Thomas McGrath, Nick S. Jones, Pieter Rein ten Wolde, and Thomas E. Ouldridge

Phys. Rev. Lett. 118, 028101 (2017) - Published 10 January, 2017

An enzyme in a chemical bath can act as an autonomous biochemical device that exploits information to do work.

EDITORS' SUGGESTION

Metabolic Trade-Offs Promote Diversity in a Model Ecosystem

Anna Posfai, Thibaud Taillefumier, and Ned S. Wingreen

Phys. Rev. Lett. 118, 028103 (2017) - Published 12 January, 2017

A new ecosystem model, which accounts for metabolic trade-offs between coexisting species, shows that population diversity can increase even when species compete for the same limited nutrients, a finding that replicates nature.
