Study links rising U.S. e-cigarette use to rise in smokers quitting

LONDON (Reuters) - A rise in the use of electronic cigarettes among American adults is linked to a significant increase in the numbers of people quitting smoking, researchers said on Wednesday.

Senate aims for a 'skinny' Obamacare repeal as other options fail

WASHINGTON (Reuters) - Republican U.S. Senate leaders, struggling to keep a seven-year-old promise to end Obamacare, turned their focus on Wednesday to passing a slimmed-down "skinny" repeal measure that would throw the issue into negotiations with t...

Supplementation of Nucleosides During Selection Can Reduce Sequence Variant Levels in CHO Cells Using GS/MSX Selection System

In the process of generating stable monoclonal antibody (mAb) producing cell lines, reagents such as Methotrexate (MTX) or Methionine Sulfoximine (MSX) are often used. However, using such selection reagent(s) increases the possibility of having higher occurrence of sequence variants in the expressed antibody molecules due to the effects of MTX or MSX on de novo nucleotide synthesis. Since MSX inhi...

Secondary metabolite production from industrially relevant bacteria is enhanced by organic nanofibers

Streptomycetes are exploited for the production of a wide range of secondary metabolites, including antibiotics. Therefore, both academic and industrial research efforts are focused on enhancing production of these precious metabolites. So far, this has been mostly achieved by classical or recombinant genetic techniques, in association with process optimization for either submerged or solid state ...

Unique roles for histone H3K9me states in RNAi and heritable silencing of transcription

Heterochromatic DNA domains have important roles in the regulation of gene expression and maintenance of genome stability by silencing repetitive DNA elements and transposons. From fission yeast to mammals, heterochromatin assembly at DNA repeats involves the activity of small noncoding RNAs (sRNAs) associated with the RNA interference (RNAi) pathway. Typically, sRNAs, originating from long noncod...

Synergy of synthesis, computation and NMR reveals correct baulamycin structures

Small-molecule, biologically active natural products continue to be our most rewarding source of, and inspiration for, new medicines. Sometimes we happen upon such molecules in minute quantities in unique, difficult-to-reach, and often fleeting environments, perhaps never to be discovered again. In these cases, determining the structure of a molecule—including assigning its relative and absolute...

Spontaneous breaking of rotational symmetry in copper oxide superconductors

The origin of high-temperature superconductivity in copper oxides and the nature of the ‘normal’ state above the critical temperature are widely debated. In underdoped copper oxides, this normal state hosts a pseudogap and other anomalous features; and in the overdoped materials, the standard Bardeen–Cooper–Schrieffer description fails, challenging the idea that the normal state is a simpl...

Neuromorphic computing with nanoscale spintronic oscillators

Neurons in the brain behave as nonlinear oscillators, which develop rhythmic activity and interact to process information. Taking inspiration from this behaviour to realize high-density, low-power neuromorphic computing will require very large numbers of nanoscale nonlinear oscillators. A simple estimation indicates that to fit 108 oscillators organized in a two-dimensional array inside a chip the...

Significant and variable linear polarization during the prompt optical flash of GRB 160625B

Newly formed black holes of stellar mass launch collimated outflows (jets) of ionized matter that approach the speed of light. These outflows power prompt, brief and intense flashes of γ-rays known as γ-ray bursts (GRBs), followed by longer-lived afterglow radiation that is detected across the electromagnetic spectrum. Measuring the polarization of the observed GRB radiation provides a direct pr...

Global health: Towards polio eradication

Polio has almost been eradicated. A field study demonstrates that a combination of focused science and epidemiology, and community-based integrated health approaches, are required to finish the job.

Organic chemistry: Molecular structure assignment simplified

An innovative combination of chemical synthesis, theory and spectroscopy could simplify determination of the structures of naturally occurring, biologically active molecules, which are often leads for drug discovery. See Letter p.436

Applied physics: A new spin on nanoscale computing

A nanoscale magnetic device that mimics the behaviour of neurons has been used to recognize audio signals. Such a device could be adapted to tackle tasks with greater efficiency than conventional computers. See Letter p.428

Can we predict protein from mRNA levels?

Arising fromM.Wilhelmet al. Nature509, 582–587 (2014); doi:10.1038/nature13319Prediction of protein levels from mRNA levels has long been fraught with unreliability and a lack of precision. However, Wilhelm et al. claimed that

Imaging: History's take on the atomic forge

Sergei Kalinin and colleagues discuss the latest developments in manipulating matter at the nanoscale, using beams of electrons in aberration-corrected scanning transmission electron microscopes (STEMs) (Nature539, 485–487;10.1038/539485a2016). Such investigations have a long history of success, hidden

Thirty Meter Telescope: Alternative telescope site is a good back-up

Your report on discussions about a possible location for the Thirty Meter Telescope (TMT) calls for some clarification (Naturedoi.org/b9px (2017); see also Naturedoi.org/b9pz; 2016). Although the TMT board's preferred site is Mauna Kea in Hawaii, the alternative

Biodiversity: Factor in species' conservation value

I agree that we need to consider the diversity of species' functions, particularly those that are crucial for maintaining ecosystems (Nature546, 22–24;10.1038/546022a2017). However, functional diversity alone is not enough if we are to reach global conservation

Open data: support from Swiss funder

You err in citing the Swiss National Science Foundation (SNSF) as a funding agency that forbids its grant-holders to use commercial data platforms such as figshare (Nature546, 327;10.1038/546327a2017). The SNSF strongly supports the sharing of data and open

Open data: enforce materials sharing

The deposition and sharing of research materials is an often-overlooked but crucial aspect of the debate on open data, even though deposition is straightforward and free of charge (see Nature546, 327;10.1038/546327a2017). Although Nature, for instance, has a clear
