You may have heard of the replicability crisis in science, and practices like outcome switching and p-hacking. BuzzFeed reports on a paper that proposes a solution: rather than assign statistical significance at $p=0.05$, change this value to $0.005$.
Sir David Spiegelhalter is quoted saying: “Dealing with the size of the p-value fixes some things. But it’s not dealing with the most important issues.” There’s a lot more in the BuzzFeed article and the full paper.

As of next month, you’ll be able to type TeX maths into Office 365 apps and it’ll work.
See the announcement on the Microsoft Developer blog for more details. Warning: it’s a bit complicated.
Once upon a time (2011), there launched an online LaTeX editor called ShareLaTeX. The very next year, there launched an online LaTeX editor called writeLaTeX. In 2015, writeLaTeX rebranded as Overleaf. Both Overleaf and ShareLaTeX offer browser-based LaTeX editing. Think of it like Google Docs for LaTeX. Both operate under a freemium model. If you use one of them, know that the other is fairly similar. If (like me) you were vaguely aware that there was an online LaTeX editor out there without using it, it was probably one of these or the other (or, I’m pretty sure, both at different times). Though note that these are not the only browser-based LaTeX editors – a native operating system ‘B’ means browser-based in this Wikipedia list of TeX editors and there are currently ten Bs in the list.
Recently, Overleaf fully acquired ShareLaTeX (Scribtex Limited) and plans to integrate the two products into one. The announcement says everyone from both teams will continue to be involved. The announcement contains more detail, a FAQ list and the following explanation.
What does this mean for you as an Overleaf or ShareLaTeX user? No worries! You won’t see any big change in the near future. Both services you know and love will continue to serve you as you have come to expect and be supported by the combined Overleaf and ShareLaTeX team. Over the coming months, we will be working on merging Overleaf and ShareLaTeX together into a single service. We aim to make the transition as smooth as possible. As we develop the combined service, we are actively seeking your feedback and input, starting with this survey. Ideally the only differences you will notice are the improvements to the editor you are currently using.
Exciting News — ShareLaTeX is joining Overleaf on the Overleaf Blog.
Also: ShareLaTeX Joins Overleaf on the ShareLaTeX Blog, which appears to be the same text.

As of this month, maths person Evelyn Lamb and colleague Kevin Knudson are producing a regular weekly maths podcast called ’My Favorite Theorem’.
They plan to spend each episode talking with a mathematical professional about their favourite result in mathematics, as well as something which goes with it, such as a foodstuff or real-world object which analogises well (like choosing a wine paired with a meal). The episodes are fairly short – both released so far are under 25 minutes – and the first one focuses on the hosts’ own favourite theorems. If you can get past the US spelling of favourite, it’s an enjoyable listen and covers some cool topics.

We don’t have lots of time to write in-depth posts about maths news any more, what with having jobs and families to attend to, so we’ve set up this new Subscripts format for when we’ve seen a thing and want to share it but don’t have time to do any more than that.
The editorial board of the Journal of Algebraic Combinatorics have announced they’re leaving Springer and setting up a new journal called Algebraic Combinatorics. The new journal will follow the principles of Fair OA – the key points are that the journal will be free to read, fees will be low, and acceptance won’t depend on ability to pay.
Hugh Thomas, one of the editors of Algebraic Combinatorics, said of the move,
“There wasn’t a particular crisis. It has been becoming more and more clear that commercial journal publishers are charging high subscription fees and high Article Processing Charges (APCs), profiting from the volunteer labour of the academic community, and adding little value. It is getting easier and easier to automate the things that they once took care of. The actual printing and distribution of paper copies is also much less important than it has been in the past; this is something which we have decided we can do without.”
Another victory for fair and sensible maths publishing, brought about by a small group of OA advocates set up by Mark Wilson and including Timothy Gowers. There’s much more about what’s happened and why you should support the new journal on Gowers’s weblog.
Algebraic Combinatorics lives at algebraic-combinatorics.org (can you believe that was available?!)
Hamish Todd offers Virus, the Beauty of the Beast, an interactive documentary about viruses. Viruses have protein shells made of patterns which can be explored mathematically, and this link to tiling theory and geometric shapes provides a mathematical interest for the piece.
Hamish is a former game designer, former teacher turned PhD student in computational biology. He says:
While studying maths I had learned about viruses, and about their connection to Islamic art, which amazed me. I found it staggering that such beautiful things could surround us without most people being aware of it. I wanted to let people see it, and I knew that my game design skills could help me do that.
Apparently many viruses are arranged on what Hamish calls a ‘hexagons and pentagons’ structure (Caspar-Klug theory), and others have more exotic structures. Wikipedia says “most animal viruses are icosahedral or near-spherical with chiral icosahedral symmetry”, with other more complicated shapes also found.
As well as “interactive documentary”, Hamish calls the website an ‘explorable explanation’, which aims “to let laypeople play with the beautiful things that mathematicians and scientists spend their time with”. Overall, it seems like a nicely-produced series of interactive videos exploring an interesting topic. Give it a go!
