One of our colleagues sent us this interesting image from a national TV station. Even though the topic is very sad and concerning, the scaling of the y-axis caught our attention and left us with perplexing astonishment.
A mathematician, a physicist, and a statistician went hunting for deer. When they chanced upon one buck lounging about, the mathematician fired first, missing the buck’s nose by a few inches.
The physicist then tried his hand and missed the tail by a wee bit.
The statistician started jumping up and down saying, “We got him! We got him!”

A funny way to show the importance of describing your study/experiment in most detail and to be transparent and precise so that colleagues are able to reproduce your results…
Objective: To determine if using a parachute prevents death or major traumatic injury when jumping from an aircraft.
Design: Randomized controlled trial.
Setting: Private or commercial aircraft between September 2017 and August 2018.
Participants: 92 aircraft passengers aged 18 and over were screened for participation. 23 agreed to be enrolled and were randomized.
Intervention: Jumping from an aircraft (airplane or helicopter) with a parachute versus an empty backpack (unblinded).
Main outcome measures: Composite of death or major traumatic injury (defined by an Injury Severity Score over 15) upon impact with the ground measured immediately after landing.
Results: Parachute use did not significantly reduce death or major injury (0% for parachute v 0% for control; P>0.9). This finding was consistent across multiple subgroups. Compared with individuals screened but not enrolled, participants included in the study were on aircraft at significantly lower altitude (mean of 0.6 m for participants v mean of 9146 m for non-participants; P<0.001) and lower velocity (mean of 0 km/h v mean of 800 km/h; P<0.001).
Conclusions: Parachute use did not reduce death or major traumatic injury when jumping from aircraft in the first randomized evaluation of this intervention. However, the trial was only able to enroll participants on small stationary aircraft on the ground, suggesting cautious extrapolation to high altitude jumps. When beliefs regarding the effectiveness of an intervention exist in the community, randomized trials might selectively enroll individuals with a lower perceived likelihood of benefit, thus diminishing the applicability of the results to clinical practice.
Maze with cheese enters human trials following decades of testing on mice
“After thousands of rounds of animal testing going back to the early 1950s, I speak for everyone at Harvard when I say we are overjoyed to have finally reached our end-stage testing goal: placing full-sized adult humans in a labyrinth and forcing them to seek out cheese,” said project lead Dr. Drew Koepka…
Once upon a time in the beautiful kingdom of Datamania lived a prince named Prince Fairhair. Though he was gentle as few, and good looking too, his father would not let him choose the love of his life on his own. No, he was destined to marry a woman from the neighbouring kingdom. He did not even know her name, only that she was referred to as My Fair Lady. Before the father of My Fair Lady could accept the marriage, he had a quest for Prince Fairhair. Only by fulfilling the quest, would he be able to marry the princess. His quest was to find out how to turn water into gold. A quest that would require gathering loads of data chests and look for clues that could lead to the recipe.
Luckily, Prince Fairhair was not alone in his quest. One of the castle wings housed a number of wizards who could help him decrypt and investigate the data chests. However, it was impossible for the data wizards to go and hunt for data themselves. Thus, to assist them, a huge number of elves were trained to look for data chests. The elves had read books, journals, comics and even poetry to know where to look. The quest was about to begin, and the elves went hunting for data chests all over the kingdom of Datamania and in empires far far away.
