[1] Genetics: Variants associated with stroke
DOI: 10.1038/ng.1081

Genetic variants associated with susceptibility to stroke are reported in a study this week in Nature Genetics.

Stroke represents an increasing global public health concern, as a major cause of adult chronic disability and mortality. Approximately 80% of stroke cases worldwide are ischemic – due to a restriction of blood supply – and amongst these, the three most common subtypes are large vessel, cardioembolic and small vessel stroke.

Hugh Markus and colleagues report a genome-wide association study for susceptibility to ischemic stroke in 3,548 affected individuals and 5,972 controls of European ancestry. They classified affected individuals by stroke subtype using clinical assessment, brain and vascular imaging. They identify a genomic region newly associated with large vessel stroke, including associated variants within the HDAC9 gene, encoding a histone deacetylase protein. The team also replicate three previously reported associated loci. They find that all four of these associations show heterogeneity across stroke subtypes, suggesting that there is a different mechanism predisposing to these subtypes.

[2] Materials: Ultrastable polymer glasses
DOI: 10.1038/nmat3234

Glassy polymer films that are 40% less dense and considerably more stable against ageing than standard acrylic glass are described online in Nature Materials this week. The new glasses may find use in nanotechnology and biomedical applications where polymer weight and stability are critical.

To make the glassy films, Rodney Priestley and colleagues used a pulsed laser to gently evaporate molecules out of a frozen dilute solution of standard acrylic glass — poly(methyl methacrylate) (PMMA), which is widely used in automobiles, buildings and orthopaedic surgery. The evaporated PMMA molecules were deposited on a substrate and formed a film. Using atomic force microscopy, the authors found that unlike the unstructured standard PMMA glasses made by rapidly cooling the liquid, the new glassy films consisted of stable polymer nanoglobules. They propose that the globular nanostructure confers the lower density and higher thermal and kinetic stability — in particular, a 40-degree-higher glass transition temperature and a glass-to-liquid transformation rate a hundred times slower than standard PMMA glass.

The authors also note that the fabrication of nanostructured ultrastable glasses from other polymers by pulsed-laser evaporation and deposition should be possible.

[3] Chemical Biology: Protein design – now with metals!
DOI: 10.1038/nchembio.777

Computationally-designed zinc-containing enzymes that can degrade molecules that are similar in structure to the nerve agent sarin are reported online this week in Nature Chemical Biology. Rational design of proteins has made important progress in recent years, identifying protein sequences with new protein folds and new enzyme activities. However, little attention has been paid to integrating metals into these systems. The incorporation of metals illustrated in this work – capable of catalyzing a wide variety of unusual reactions – should greatly broaden the reactions that are possible in protein design.

David Baker and colleagues survey a wide number of known zinc-containing enzymes to identify 12 that have shapes that could be redesigned for their new reaction. They found that one of these enzymes did show some activity in breaking apart an organophosphate molecule. Further engineering by the team, guided in part by a crystal structure of the new enzyme, led to a successful enzyme.

[4] Geoscience: Volcanic cooling not recorded by tree rings
DOI: 10.1038/ngeo1394

Reconstructions of past climate on the basis of tree rings may miss the short-lived cooling events caused by volcanic eruptions, reports a paper published online this week in Nature Geoscience. The work suggests that, in particular, the tree-ring-based reconstructions may be missing cooling linked to the ad 1258–1259 eruption of an unidentified volcano.

Tree-ring chronologies are often collected from regions that are at or near the minimum temperature for tree growth. Michael Mann and colleagues used numerical simulations of climate and tree growth to show that when temperatures fall abruptly for one or two growing seasons, trees in these regions undergo little or no growth. The resultant lack of a tree ring corresponding to the period of cooling thus masks the climate event in subsequent reconstructions.

These results show that a 2 °C cooling associated with the ad 1258–1259 eruption (as indicated by climate models) cannot be excluded by existing tree-ring data.

[5] Immunology: A cytokine’s secrets revealed
DOI: 10.1038/ni.2227

Interleukin-35 (IL-35) – a protein secreted by certain T cells – has important immunosuppressive properties and how it achieves these effects is reported online in Nature Immunology this week.
Dario Vignali and colleagues determine the receptor for IL-35 and show it to be composed of a novel combination of known receptor components. Engagement of this receptor triggers a unique sequence of downstream signaling molecules which are responsible for suppressing target cells and – if the target is a T cell – converting it into another IL-35-expressing cell which is in its turn suppressive.
This study highlights how the immune system can use modular receptor and cytokine components in different combinations to elicit distinct functional consequences.

[6] Methods: Finding mistakes in yeast gene libraries
DOI 10.1038/nmeth.1890

A method for uncovering the extent that scientists incorrectly assigned gene function in libraries of mutated yeast genes is reported online in Nature Methods.
Comprehensive libraries of mutated genes in yeast are a workhorse for geneticists, and are widely used to assign gene function in genetic screens and genomics studies. But a ‘neighboring gene effect’ has been documented anecdotally, in which the neighbor of the mutated gene—not the gene itself—is actually responsible for the phenotype.
Martin Kupiec and colleagues show that the neighboring gene effect is in fact widespread, affecting on the order of one in ten genes in a prominent deletion collection. They develop and introduce freely available software that uses publicly available protein interaction data to predict the gene that truly causes a given phenotype with high accuracy.

[7] And finally…Methods: Studying monkey and human brain similarities
DOI: 10.1038/nmeth.1868

A method to find regions of the brain with similar function in both monkeys and humans is reported online this week in Nature Methods. This method could open new avenues for building more accurate evolutionary models.
Previous studies have used functional magnetic resonance imaging (fMRI) to compare how the brains of human and non-human species respond to a particular stimulus or activity. To interpret comparative fMRI studies, researchers often rely on prior knowledge of the anatomical similarity between brain regions.
Wim Vanduffel and colleagues developed a technique, interspecies activity correlation (ISAC), which can help find regions with similar functions without considering differences in the brains’ anatomy. The ISAC method is based on the premise that functionally corresponding regions should have a similar time course of activity in both species if they respond to the same features—for example, hands, faces, objects and so on—even if their anatomical location differs.
The authors validate the ISAC method by studying the similarities in fMRI responses between humans and monkeys exposed to the same clips from the movie The Good, the Bad and the Ugly. Their findings suggest that some human and monkey brain areas might have been functionally reorganized in unexpected ways.
In an accompanying News and Views article, Tor Wager and Tal Yarkoni discuss some of the limitations and challenges that the method faces and the i
mportance of corroborating the putative homologies in future studies.
