An injectable gel tested in living zebrafish can use the animals’ internal chemistry to transform into a conductive polymer.
When the gel is mixed with the recipient’s own metabolites — chemicals generated by the body’s processes — a chain reaction turns it into a solid but flexible material.

At ethanol concentrations of 59 vol-% or higher, guaiacol is increasingly surrounded by ethanol molecules and is driven to the bulk. This indicates that the taste of guaiacol in the whisky would be enhanced upon dilution prior to bottling. Our findings may apply to other flavour-giving amphipathic molecules and could contribute to optimising the production of spirits for desired tastes.

An editor on the board of a journal published by the prestigious American Psychological Association (APA) has been asked to resign in a controversy over data sharing in peer review. Gert Storms — who says he won’t step down — is one of a few hundred scientists who have vowed that, from the start of this year, they will begin rejecting papers if authors won’t publicly share the underlying data, or explain why they can’t.

Here we identify very recent fine-scale population structure in North America from a network of over 500 million genetic (identity-by-descent, IBD) connections among 770,000 genotyped individuals of US origin. We detect densely connected clusters within the network and annotate these clusters using a database of over 20 million genealogical records.

One of the world’s most influential global health charities says that the research it funds cannot currently be published in several leading journals, because the journals do not comply with its open-access policy.
Including Nature itself.

It was hailed as an elegant confirmation of Einstein’s general theory of relativity — but ironically the discovery of gravitational waves earlier this year could herald the first evidence that the theory breaks down at the edge of black holes.
