Human brain organoids on a chip reveal the physics of folding, Published online: 19 February 2018; doi:10.1038/s41567-018-0046-7

Wrinkling in human brain organoids suggests that brain development may be mechanically driven, a notion supported only by model gels so far. Evidence in this simple living system highlights roles for cytoskeletal contraction and nuclear expansion.

Photoexcitation circular dichroism in chiral molecules

Photoexcitation circular dichroism in chiral molecules, Published online: 19 February 2018; doi:10.1038/s41567-017-0038-z

Photoexcitation circular dichroism generates an ultrafast response in chiral molecules, with a much higher sensitivity than standard circular dichroism.

Rethinking pattern formation in reaction–diffusion systems

Rethinking pattern formation in reaction–diffusion systems, Published online: 19 February 2018; doi:10.1038/s41567-017-0040-5

Canonical pattern formation relies on a system being close to an instability and stabilized by nonlinearities — but real systems seldom conform to these conditions. A new theory solves the problem by recasting it in terms of moving local equilibria.

A new wrinkle on the brain, Published online: 19 February 2018; doi:10.1038/s41567-018-0057-4

The folded structure of the human brain is a hallmark of our intelligence — an optimized packing of neurons into a confined space. Similar wrinkling in brain-on-a-chip experiments provides a way of understanding the physics of how this occurs.

Experimental discovery of nodal chains, Published online: 19 February 2018; doi:10.1038/s41567-017-0041-4

Nodal chains are observed for the first time in a photonic crystal with accompanying drumhead surface states. This will stimulate further study of topological nodal lines with non-trivial connectivity.

Liquid beyond the van der Waals paradigm, Published online: 12 February 2018; doi:10.1038/s41567-018-0052-9

An ultracold mixture of Bose gases is eight orders of magnitude more dilute than water. However, quantum fluctuations turn it into a self-bound liquid droplet.

Geodesy and metrology with a transportable optical clock, Published online: 12 February 2018; doi:10.1038/s41567-017-0042-3

An atomic clock has been deployed on a field measurement campaign to determine the height of a mountain location 1,000 m above sea level, returning a value that is in good agreement with state-of-the-art geodesy.

Wall roughness induces asymptotic ultimate turbulence, Published online: 12 February 2018; doi:10.1038/s41567-017-0026-3

Turbulence is seldom confined by boundaries that are perfectly smooth, but wall roughness is usually ignored. A study of flows between rotating cylinders suggests that roughness enhances turbulent transport and alters its scaling behaviour.

Bringing next-generation atomic clocks out of the lab is not an easy task, but doing so will unlock many new possibilities. As a crucial first step, a portable atomic clock has now been deployed for relativistic geodesy measurements in the Alps.

Interaction modifiers in artificial spin ices, Published online: 12 February 2018; doi:10.1038/s41567-017-0027-2

Coupling strengths differ between neighbours in square artificial spin ices, resulting in the loss of degeneracy. Introducing mesospins on vertices of the array alleviates this problem, by tuning the strength and ratio of the interaction energies.

Ultimate evidence for the ultimate regime

Ultimate evidence for the ultimate regime, Published online: 12 February 2018; doi:10.1038/s41567-017-0034-3

The ultimate regime of turbulence has been observed, more than half a century after its first prediction. Inspiration for achieving this technical feat came from the imperfections of an everyday pipe.

Dynamics of interacting fermions under spin–orbit coupling in an optical lattice clock, Published online: 05 February 2018; doi:10.1038/s41567-017-0029-0

Many-body effects in an interacting spin-orbit coupled Fermi gas are studied with the help of clock spectroscopy. The results provide a simple view of how strong collective dynamics arise from local interactions in the presence of spin–orbit coupling.

A large-scale density matrix renormalization group study of the dipolar Heisenberg model reveals evidence for quantum spin liquid ground states on both triangular and kagome lattices.

Experimental evidence for superionic water ice using shock compression, Published online: 05 February 2018; doi:10.1038/s41567-017-0017-4

Although predicted to occur in planetary interiors, superionic water ice has proved elusive to identify experimentally. Laser-driven shock-compression experiments on water ice VII now verify its existence.

Bilinear magnetoelectric resistance as a probe of three-dimensional spin texture in topological surface states, Published online: 05 February 2018; doi:10.1038/s41567-017-0039-y

A method for resolving the spin texture of the surface state of a topological insulator using a transport measurement is developed. Understanding the spin texture will help engineer spintronic devices.
