DNA synthesis for true random number generation

Secure data encryption increasingly needs large volumes of true random numbers. Linda Meiser et al. use the stochastic nature of DNA synthesis to obtain millions of gigabytes of unbiased randomness.

  • Optical analog computing has so far been mostly limited to solving a single instance of a mathematical problem at a time. Here, the authors show that the linearity of the wave equation allows to solve several problems simultaneously, and demonstrate it using an MW transmissive cavity.

  • Geometric E to Z double C=C bond isomerization is challenging as it requires kinetic trapping of the Z-isomer with injection of chemical energy. Here, the authors report a dinuclear Pd(I)−Pd(I) complex that mediates selective isomerization of E-1,3-dienes to the Z-isomers without photoirradiation.

  • The process of thin sheet crumpling is characterized by high complexity due to an infinite number of possible configurations. Andrejevic et al. show that ordered behavior can emerge in crumpled sheets, and uncover the correspondence between crumpling and fragmentation processes.

  • Converse symmetry breaking is a counterintuitive phenomenon in which the system must have an asymmetry to stabilize a symmetric state. Molnar et al. demonstrate this effect in real power-grid networks and show that synchronous operation can be improved by inhomogeneities across power generators.

  • The unprecedented cost of the 2018 eruption in Hawai’i reflects an intersection of disparate physical and social phenomena: widely spaced, highly destructive eruptions, and atypically high population growth. These were linked and the former indirectly drove the latter with unavoidable consequences.

  • Neural recording technologies increasingly enable simultaneous measurement of neural activity from multiple brain areas. To gain insight into distributed neural computations, a commensurate advance in experimental and analytical methods is necessary. We discuss two opportunities towards this end: the manipulation and modeling of neural population dynamics.

  • Writing in Nature communications, Zhu and collaborators reported the development of a genetically encoded sensor for the detection of formaldehyde in cells and tissues. This tool has great potential to transform formaldehyde research; illuminating a cellular metabolite that has remained elusive in live structures.

  • Many newly-discovered microbial phyla have been studied solely by cultivation-independent techniques such as metagenomics. Much of their biology thus remains elusive, because the organisms have not yet been isolated and grown in the lab. Katayama et al. lift the curtain on some intriguing biology by cultivating and studying bacteria from the elusive OP9 phylum (Atribacterota).
