Joe Cartledge invented the jockstrap (or athletic supporter) in the 1920s. He played hockey, football, and rugby so his invention may have been inspired by painful, painful memories. It was marketed as “Protex.”
When it’s negative to be positive.
When it struck, the contagion spread fiercely. The deadly severe acute respiratory syndrome (SARS) outbreak in South China in 2002 infected thousands, and ultimately killed nearly 800 people.
But where did this lethal strain come from? We may now have our answer, with a study showing bats living in a single cave in China possess all the building blocks of the deadly SARS coronavirus – and potentially the means to create a new one.
Researchers from the Chinese Academy of Sciences spent five years analysing SARS viruses found in multiple species of horseshoe bats nesting in a cave in China’s Yunnan Province.
In all, the team identified 11 new strains of SARS virus carried by the bats, and a genomic analysis of these – along with strains from the same cave identified in previous research – revealed something interesting.
Previous research had suggested bat viruses could have been responsible for SARS, but scientists had never uncovered evidence of a direct ancestor to the human-infecting coronavirus in bat strains.
In the new research, that held true again – none of the viruses from the cave by themselves displayed the genetic traits of the SARS coronavirus that spread to humans, infecting more than 8,000 people during the 2002-2003 emergency.
But together, it was a different story. In this one cave, there were enough genetic ingredients among the strains to build the virus that kills humans.
“Importantly, all of the building blocks of SARS-CoV genome, including the highly variable S gene, ORF8 and ORF3, could be found in the genomes of different SARSr-CoV strains from this single location,” the researchers explain in their paper.
Hypothetically speaking, the team suggests it’s possible – even probable – that if the right strains mixed with one another in the cave, you’d end up with the direct ancestor of a virus that can infect and kill people.
The findings are reported in PLOS Pathogens.

Xpand Your Horizons is a growing online community that shares videos and other material aimed to intrigue people to think outside the box and expand the interest all around. The Xpand Your Horizons Family is sometimes shortened to "XYH" or "XYHor" here on Tumblr in our many secondary and more specific blogs. Our Family has compiled more than 60 playlists on YouTube now and has viewed every video to make sure that what is delivered is factual. If something appears questionable or the comment feedback alludes to mistakes, research is done and it is determined whether or not it's worth sharing. As of late, it is so easy to come across videos containing little to no actual research or are so heavily boggled down with opinions that you can find yourself in a battle of so-called "whits" on the internet. The Xpand Your Horizons Family doesn’t yet upload or produce any original content...yet... but we would like to make it known that We’re sharing all this contentbecause it's important to take Science seriously in a healthy and safe environment. Each playlist can be found on YouTube under the Xpand Your Horizons moniker and their specific topic(s) is/are displayed in the title, and further explanation is in their descriptions. Not all are academic inclined, some deal with pop culture as well as media. Enjoy!For more content, Click Here and experience this XYHor in its entirety!
