The term “genome-editing” has become synonymous with CRISPR-Cas. But there’s more than one way to edit a genome, and each has its pros and cons.

The current focus on single-cell biology reflects the growing awareness among life scientists that all cells are not alike.
In the genomics world, methods such as scRNA-seq and Drop-seq allow researchers to probe cellular heterogeneity at the genetic level using next-gen DNA sequencing. Mass spectrometry imaging (MSI) does likewise for protein and metabolite studies.
TechBlog: New tools track article buzz online
“How’s my paper doing?” It’s such a simple question, and in today’s hyperconnected world it’s relatively easy to work out who’s reading and talking about your scientific publications. But are there conversations you might be overlooking?

Timothée Poisot recently travelled to London for MozFest 2017, “The world’s leading festival for the open Internet movement.” There, the quantitative and computational ecologist at the University of Montréal in Canada ran a session entitled “Scientific computing for the terabyte-less.” Here, he tells Naturejobs why life science research needn’t necessarily follow the Big Data model.
TechBlog: Bioconda promises to ease bioinformatics software installation woes

Bioinformatics is notoriously complicated, what with its arcane command-line interface, complex workflows, and massive datasets. For the uninitiated, simply installing the software can present a problem.
A new paper on the bioRxiv preprint archive describes one possible solution, a bioinformatics-focused package collection called Bioconda.
TechBlog: Interactive figures address data reproducibility

Data reproducibility and transparency mean different things to different people, but one aspect involves allowing scientists to view and manipulate the data or code underlying published figures, both to double-check others’ work and to repeat those analyses using custom data. Over the past year, for instance, the open-access journal F1000Research has implemented integrations with Code Ocean and Plotly for viewing and manipulating programming code and figures, respectively. Now, a new publication showcases interactive figures for 3D genome analysis, too.
TechBlog: The nanopore toolbox

For this week’s Technology Feature, Michael Eisenstein wrote about the technology, applications, and challenges of nanopore DNA sequencing. In brief, the technology involves threading intact pieces of DNA through a tiny aperture in a membrane or other barrier, through which a current flows. As each base passes, it disrupts that current in a characteristic way, allowing specialized software to determine the sequence.
The technology has multiple benefits: it’s relatively inexpensive and compact, and produces exceptionally long reads. But the resulting error rate is also higher than some other technologies. What that means is, informatics tools designed to handle short-read data can often stumble when confronted with nanopore sequences. But a growing collection of dedicated long-read tools is rapidly filling in the gap. I asked a few nanopore veterans to help me compile a list.
TechBlog: Jupyter powers bioinformatics, again
Bioinformatics isn’t easy for newbies. It’s typically done on the Linux command line, where users direct the computer using text-based instructions rather than clicking a mouse.
But there are alternatives. One popular choice is Galaxy; another is GenePattern. Both allow researchers to execute complex bioinformatics tools via open-source, point-and-click, web-based interfaces, freeing them from the burdens of the command line, programming, and software installation. As such, they make bioinformatics workflows relatively user-friendly. And that trend is continuing.
TechBlog: HiPiler simplifies chromatin structure analysis
For my recent Toolbox on 3D genome visualization tools, Nils Gehlenborg at Harvard Medical School clued me into two interesting pieces of software. One, HiGlass, was included in my article; a related tool, HiPiler, was not. But that doesn’t mean it’s not worth talking about.
TechBlog: Mike Goodstadt: A circuitous route to bioinformatics
{credit}CNAG-CRG{/credit}
Most coders come to bioinformatics by one of two routes. They’re either biologists skilled in programming, or programmers with an interest in biology. Mike Goodstadt, the programmer behind the genome-visualization tool TADkit, took a different approach.
In the early-to-mid 1990s, Goodstadt was a student at the University of Bath in the UK. His course of study: Architecture. Continue reading
