[NOTE: The paper was retracted, as described below—here is an updated link to a copy of it.] In the spirit of the Ig Nobel Prize-winning dead salmon study (and subsequent studies that went looking for fishy things) comes this new study about Covid-19, cat images, and some limitations of technology: “Can Your AI Differentiate Cats […]

fMRI of the Brains of People Eating High and Low Quality Steak
A further innovation in the study of the brain, and/or in the study of people eating cooked meat: “Neural connectivity of the right and left nucleus accumbens after eating high and low quality steak,” W.N. Tapp, T.H. Davis, D. Paniukov, and Markus F. Miller [pictured below], Meat Science, vol. 112, February 2016, p. 113. The authors, […]
MRI: tool use progresses from medicine to pork pie development
A tool often used to assess the quality of, or damage to, human bodies can also be used to assess the quality of, or damage to, an object that will be ingested into one of those human bodies. Details appear in this study: “Magnetic Resonance Imaging: A Tool for Pork Pie Development,” Adam P. Gaunte, Robert […]
Falling Snowflakes: vertical or horizontal?
In 2009, researchers at the Department of Atmospheric Sciences, of the University of North Dakota, US, presented (in association with the Instrumentation Sciences Branch, NASA Goddard Space Flight Center) details of their Snowflake Video Imager (SVI). It was fully described in a paper for the Journal of Atmospheric and Oceanic Technology. The imager, which linked […]
Childish: 2nd-hand looks at brain activity
Some brain scientists use their brains to explain how they think other people’s brains are used. They also use (in addition to their brains) fMRI [functional magnetic resonance imaging], a technique in which complex equipment measures some of the things that happen inside a brain while a person is using that brain. (NOTE: the technique has […]
Why brain extraction is not as bad as it sounds
Scientists marvel at how other scientists – the ones who study something other than what they themselves study – give strange meanings to common words. Evan Shellshear, at Fraunhofer Chalmers Centre in Gothenburg, sent me an example, a study called Fast Robust Automated Brain Extraction. Shellshear said: “I stumbled across this article somehow [whilst] looking for […]
More NMR rides: Through Ugli and Okra
Think of this as Thrilling Virtual Rides Through Food (before the food takes a thrilling ride through you), part 2. Here are two more of Andy Ellison’s magnetic resonance images of foods. (He makes them into animated GIFs, which give a sort of thrilling quick ride through the food from one end, or side, or […]
Magnetic resonance imaging of berries, bamboo
Think of this as Thrilling Virtual Rides Through Food (before the food takes a thrilling ride through you), part 1. Andy Ellison does some lovely magnetic resonance imaging of foods. (Presumably he does other things, too. But we will concentrate here only on the foods). (He makes them into animated GIFs, which give a sort […]
A bottle beyond the behind (x-ray)
The New England Journal of Medicine featured this image in October 2010, with the description: A 35-year-old man presented to the emergency department… he was found to be intoxicated… plain-film radiography of the abdomen was performed, and an intact bottle was seen in the rectosigmoid colon. Laparotomy revealed a glass bottle of beer lodged in […]
A 2D face of 3D dental research
Science Illustrated describes 3D-imaging dental research conducted at the Fraunhofer Institute for Applied Optics and Precision Engineering. The profile features this attractive 2D-image:
