Questions of the Week

Why do raw and cooked eggs rotate differently?
Put a raw egg on a flat table, and give it a good spin with two fingers. The egg spins, however, rather slowly because the liquid inside poorly exchanges momentum with the outside shell. Thus, when you spin the egg by applying force to the shell, most of the inside resists the motion and the friction forces between the inside (immobile) and the shell (mobile) will be slowing down the egg’s speed. But if you consider a cooked egg, proteins contained inside the egg are now forming a solid phase that is tightly joint to the shell. In that case, there are no friction forces in the “egg system” and […]
How normal glass can be (nearly) indestructible – The secret of the Prince Rupert’s Drop
Ordinary glass as it is used for windows can exhibit exceptional behaviors and even shred a riffle bullet to pieces, furthermore it can help to make car windows safer and to understand the inner processes in volcanos. Key to all these fascinating properties are the so-called Prince Rupert’s Drops. These structures are solidified drops of glass, which are produced by letting a drop of molten glass fall into a bucket of water. The sudden shock caused by the massive temperature drop on the surface of the glass basically locks in the outer shape of the drop, preserving main body and tail. (Fig. 1) [1,2,3]. This object has now very unique […]
Why Does Alcohol Burn in Wounds ?
Have you ever wondered why rubbing alcohol, i.e. isopropyl alcohol, which is used to disinfect cuts burns so much when applied to the wound? As my mother always said: “As long as it burns, it helps”. This didn’t help me much as a kid, anyway. But why does it burn in the first place? Do you feel the bacteria die? Do some of your cells get killed, too, and you feel that? In fact, neither is true. Interestingly, the pain you feel is due to a heat reaction. But wait, doesn’t alcohol usually give you a cool sensation when applied to the skin? True, but when the alcohol is able […]
Will It Ever Be Possible To Successfully Transplant Heads ?
According to media reports, the Italian neurosurgeon Dr. Sergio Canavero will attempt the first transplant of a human head (cephalosomatic anastomosis) in the end of 2017.[1] Valery Spiridonow is volunteering for this project since he suffers from spinal muscular atrophy (SMA) and believes the surgery will offer a chance to escape from this fatal disease.[2] Similar experiments have already been performed more or less successfully on animals. In some cases, the animals survived but they remained paraplegic and their cardiovascular and respiratory systems had to be supported. Also they did not survive quite long after the surgery.[3,4] In fact, many experts are strongly doubting the success of this highly expensive […]
How does a touchscreen work ?
Touchscreens are getting more and more important for modern media. The most striking advantage of this technology is the combination of intuitive in- and out-put devices, which allow the user to directly interact with the system and vice-versa. But how does such a screen work, which types are available, and why do certain type of touchscreens react to fingers, but not to a normal pen? These questions we will answer in this week’s featured question. One of the first touchscreen technologies (that is still in use nowadays) is the so-called resistive screen. This specific screen type is composed of two conductive, relatively transparent layers (usually indium-tin-oxide (ITO)), which are held […]

Dear Reader,

In this first issue of the 5th volume of JUnQ, we chose Family & Career in Science as a topic because we wondered, if it is possible to undertake a successful career in science on the one hand while having a family on the other. Especially as a young researcher who still needs to make a name for himself in science, there is a lot of pressure from the academic society and one would think (at least I do) that these young researchers do not have any time to have a family. But in fact, this is not what reality looks like. Most professors I know or that I have visited lectures from during my studies — male or female — all have a family and children. One of the supervisors of my doctoral thesis is a young researcher himself who has a wife and a little son and his wife is also working a very ambitious job with a tight schedule. So the question is not really if but how this is feasible in particular as a woman but also as a man.

Katharina Landfester

Prof. Dr. Katharina Landfester is a director at the Max Planck Institute for Polymer Research in Mainz. Together with her husband Dr. Volker Mailänder, she has two children. In a very personal assay, Prof. Landfester describes her experience as a woman and mother in the scientific world and how they managed to balance their scientific careers and family life showing us why instead of hesitating, sometimes it is best to just do it.

Till Opatz is full professor of organic chemistry at the University of Mainz. He took up his position in Mainz in 2010 after working as a professor in Hamburg, where his wife holds a position as professor for developmental neurophysiology. They have a 17 months old daughter and we were wondering how the family life with two parents in such demanding positions can be managed. In between his busy schedule as a professor and father, Prof. Opatz took the time to answer some questions about the difficulties that parents in academia have to face.

Since 2011, the Family Service Center at the University of Mainz is the central institution for parents and university members taking care of relatives. It is dedicated to the support of students and university employees through the collection and improvement of services aimed specifically at parents. Stefanie Schmidberger is project manager at Family Service Center Mainz. She studied the History of Art, Book Studies, and German Language in Mainz. Furthermore, she is trained in career and educational guidance.

We are very pleased to announce the publication of the latest issue of JUnQ. With a fresh start into our fifth year, we address the topic of “Family & Career in Science”. To tackle this topic, we talked with Stefanie Schmidberger from the Family Service Center at the Johannes Gutenberg-University Mainz about the childcare situation for parents working and studying in Mainz. Furthermore, we have an interview with Prof. Till Opatz (Mainz University), who balances his academic career, a long distance marriage and paternity.

In our commentary section “Views on Life, the Universe, and Everything”, Natascha Gaster, Jorge S. Burns and Michael Gaster talk about single author papers becoming scarce in scientific publications.

We hope you enjoy reading our latest issue!

Sexual promiscuity can be studied quantitatively as a behavior. The qualitative study of the emotions and motives associated with promiscuity is secondary. When heterosexual behavior is studied quantitatively promiscuity is necessarily equal among males and females. In other words, contrary to contemporary popular opinion, the group of human males and the group of human females have the same average number of sex partners.

In the last couple of years, partly because of my involvement in the stripy controversy (more below), I have thought a lot about publishing… and concluded (along with many other people) that the system is absurd, worse, toxic. Public funds are paid to commercial publishers to put publicly-funded research behind paywalls. The (unpaid) hard work of reviewers (which may or may not have led to improvements in the article) remains confidential and does not benefit the community. Publicly-funded researchers waste their time reviewing articles which have already been reviewed several times by other researchers for other journals. Researchers are evaluated on the impact factor of the journals in which they publish even though this is not at all a mea- surement of the quality of an article.[1,2] There is a serious reproducibility crisis[3] but no incentive to reproduce or criticise published work. Those flaws and their consequences can be illustrated by briefly looking at two recent controversies.

Over the last years the number of manuscripts published by single authors has diminished. This is despite single author articles having qualities unattainable in multi-author-papers. They present an opportunity to publish opinionated and creative thoughts unbound by compromise. Moreover they represent a unique vision of the research process. This being said they may be undervalued, as they are appraised similarly to the multi-author manuscripts and this might call for a change in evaluation metrics.
