Researchers have fired up an 1895 x-ray machine to compare its images to that of a modern system. A physician from Maastricht University Medical Center in the Netherlands dusted off the antique machine, built by a local hospital director and high school director just weeks after X-ray discoverer Wilhelm Roentgen described his own system in a scientific journal. The pair, H J Hoffmans and Lambertus Theodorus van Kleef, homebrewed their machine from parts scavenged from the high school. The antique, operating under the same conditions outlined by Hoffmans and van Kleef, required a radiation dose 1,500 times higher than delivered by the current system to achieve comparable results. The antique's image is the one on the left. From the BBC News:
The team carefully recreated the experimental conditions that the machine's inventors would have used.
Given that a high radiation dose might be required to carry out the tests, the team obtained a hand from a cadaver as their imaging subject - rather than the "young lady's hand" listed in Hoffmans and van Kleef's notes...
"Our experience with this machine, which had a buzzing interruptor, crackling lightning within a spark gap, and a greenish light flashing in a tube, which spread the smell of ozone and which revealed internal structures in the human body was, even today, little less than magical," they wrote.

Researchers successfully revived ancient microbes, some more than 100 million years old, that were buried in the seafloor. During an expedition to the South Pacific Gyre, the scientists from the Japan Agency for Marine-Earth Science and Technology (JAMSTEC) and their colleagues drilled into the ocean sediment almost 6,000 meters below the surface. “Our main question […]
My family stopped wiping down all our groceries to “disinfect” them a couple months ago, mostly because of hygiene exhaustion. Then in May, the Center for Disease Control and Prevention clarified its own Web page about how COVID-19 spreads to state that “based on data from lab studies on COVID-19 and what we know about […]
I’d totally go.
