My favorite is the use of " \; ", which would allow the cheating student being modeled by the picture to ensure legible symbol spacing when writing exam solutions.

Hurray! Science vindicates my longstanding practice, learned at age 12, of using TWO SPACES after periods in text. NOT ONE SPACE. Text is easier to read that way. Of course, on twitter, I use one space, given 280 characters. https://t.co/4xI6sVbF88 Will arm-wrestle @Neuro_Skeptic pic.twitter.com/XpEr4KFR4x— Nicholas A. Christakis (@NAChristakis) April 28, 2018

Title: Nanoptera in a Period-2 Toda Chain
Authors: Christopher J. Lustri and Mason A. Porter
Abstract: We study asymptotic solutions to a singularly perturbed, period-2 Toda lattice and use exponential asymptotics to examine "nanoptera," which are nonlocal solitary waves with constant-amplitude, exponentially small wave trains. With this approach, we isolate the exponentially small, constant-amplitude waves, and we elucidate the dynamics of these waves in terms of the Stokes phenomenon. We fi nd a simple asymptotic expression for these waves, and we study con figurations in which these waves vanish, producing localized solitary-wave solutions. In the limit of small mass ratio between the two types of particles in the lattice, we derive a simple antiresonance condition for the manifestation of such solutions.

They’re not bad. I wouldn’t call them gorgeous, though.

As part of their correspondence today, they also let the first author (my former doctoral student) know about the option of a young-scientist, first-author spotlight. They wrote the following (which you can also find on their website):
Congratulations on acceptance of your article in Biology Open. To help early-career researchers promote themselves alongside their papers, we have launched a series of interviews with the first authors of a selection of papers published in BiO. If you would like to be included in this interview series, please tell us more about yourself by answering the questions below. You can answer all or just some of the questions, and you may also suggest additional questions and provide your answers to them if you wish.
How interesting! I have never seen a journal do this before. What a great idea! We really need to do something like this in the mathematics and physics communities.
Here are their suggested questions:
What is your scientific background and the general focus of your lab?
How would you explain the main findings of your paper to non-scientific family and friends?
What are the potential implications of these results for your field of research?
What has surprised you the most while conducting your research?
What, in your opinion, are some of the greatest achievements in your field and how has this influenced your research?
What changes do you think could improve the professional lives of early career scientists?
What's next for you?
They then added the following:
So that we can create a short biography to accompany your interview, please ensure that you include your job title, the name of the Principal Investigator of your lab, your contact address and a one-line synopsis of your research interests. Include your Twitter handle, if you have one, so we can tag you in any related tweets.
They also asked for a picture of the first author and "a particularly striking, interesting or unusual image" from their research (along with a caption describing it).

Title: On the Wonderfulness of Noether's Theorems, 100 Years Later, and Routh Reduction
Author: Raphaël Leone
Abstract: This paper is written in honour of the centenary of Emmy Amalie Noether's famous article entitled Invariante Variationsprobleme. It firstly aims to give an exposition of what we believe to be the most significant and elegant issues regarding her theorems, through the lens of classical mechanics. Despite the limitation to this field, we try to illustrate the key ideas of her work in a rather complete and pedagogical manner which, we hope, presents some original aspects. The notion of symmetry coming naturally with the idea of simplification, the last part is devoted to the interplay between Noether point symmetries and the reduction procedure introduced by Edward John Routh in 1877.

While navigating the menus, I managed to get eaten by a grue.
There are errors in some of the D & D categorizations.
The first one that I want to mention is ThinkGeek's catalog. (Tip of the cap to Jennifer Ouellette.)
As usual, there are some special papers on the arXiv, including this one and this one.
Here is another joke arXiv paper. (Tip of the cap to Chad Topaz.)
Here is a roundup of Google's jokes, including the ability to play "Where's Waldo?" on Google Maps.
