My 2017 EliteBook HP laptop broke in the most bizarre fashion, in that the battery started inflating to the point of pushing the back cover (and stopped functioning as well). It happened at the worst moment, of course, as I was boarding a train to Brittany for family matters, whose power plug kept cutting every five minutes. I did not realise the entire issue with the battery until I reached my final destination and rushed to a computer repair shop, which did not want to do anything on the spot (of course!) but pointed out to me the problem with the back cover.  Which I removed a few minutes later in a lawnmower repair shop, held by a dear cousin of mine. Now, the laptop is still working, but waiting for a new battery I ordered as soon as I saw the state of the old one..!

While standing in a train to my mother’s house in Brittany, I was catching up on earlier Nature issues and came upon this April issue where, following the retraction of a Nature paper on the topic, Sergey Frolov casts doubt on the possible detection of a new type of quantum particle, the Majorana fermion, whose existence still remains inconclusive. The criticism concentrates on the data analysis of signals where the appearance of a narrow peak should support the hypothesised existence. The article is interesting (to me) as a reflection of someone having published positive, then negative articles on the topic, upon the tendency for authors in the field to cherry-pick experiments where some peaks occur. Among dozens or hundred of experiments where they did not. And calling for open data and more stringent review(er)s on the matter (and others). The arguments in the opinion tribune sound most reasonable but I wonder whether or not other particle physicists share the same concern.
