Just 12 people account for the lion's share of anti-vaccination propaganda posted to three of the leading social media outlets, according to a study from a London-based group opposed to online hate and disinformation. According to the NPR report, a study (PDF file) conducted by the Centre for the Countering of Digital Hate identified the "Disinformation Dozen" people, including RFK Jr., Joseph Mercola, and Sherri Tenpenny, who account for 65% of the anti-vaccine content posted to Facebook, Twitter, and Instagram, and 73% of the same posted to Facebook. In its study, the group blasts the social media companies for allowing their platforms to be abused and calls for them to be de-platformed. "Living in full view of the public on the internet are a small group of individuals who... are abusing social media platforms to misrepresent the threat of Covid and spread misinformation about the safety of vaccines," the study said in its introduction. "Facebook, Google and Twitter have put policies into place to prevent the spread of vaccine misinformation; yet to date, all have failed to satisfactorily enforce those policies."

When pressed for oxygen, some fish and sea cucumbers will use their lower intestines to get a little extra out of their environment. Now, a team of Japanese researchers say that mammals are also capable of respirating through their rectal cavity, at least in a lab setting.
The team’s research is published today in the journal Med and describes the capacity for mice, rats, and pigs to survive longer and have more strength in low-oxygen circumstances when given oxygen gas or an oxygen-rich liquid through their rectums, in a process similar to an enema. While fish like loaches and catfish use a similar method to gain additional oxygen in the natural world, this doesn’t appear to be an evolutionary adaptation for mammals. In other words, mammalian bodies can’t naturally do this, but with a little push from modern science, it becomes possible. Previous research has seen oxygen injected directly into mammalian bloodstreams, prolonging the lives of rabbits, but the rectal approach to the low-oxygen problem is novel.
The experiment, while disturbing, was designed to find new ways to save the lives of people whose lungs are failing. These treatments prolonged the animals’ survival in a low-oxygen setting by staving off respiratory failure. Mice were given both the gas and liquid oxygen delivery methods, while the rats and pigs only received the liquid treatment.
In a lab-controlled hypoxic setting (a chamber that was 9.5% oxygenated), mice without the supplemental oxygenation died after about 11 minutes. With the treatment, three-quarters of the tested mice survived for nearly an hour in the same lethal conditions.
From Pigs And Rodents Can Breathe Through Their Butts, And This Could Be a Vital Discovery:
Initially, their research subjects were mice, who were thankfully anesthetized for the next part. The researchers developed an oxygen ventilation system to be inserted anally; they induced hypoxia via tracheal intubation, and compared mice ventilated intestinally to control mice who received no ventilation.
Of the control mice, not a single one survived longer than 11 minutes. This was in marked contrast to the mice receiving intestinal oxygen, 75 percent of which survived for 50 minutes.

Tor users, beware: 'Scheme flooding' probes for installed apps with custom URL schemes, it's possible to build 32-bit user profiles. Visiting the schemeflood.com site using a desktop (not mobile) browser and clicking demo generates a flood of custom URL scheme requests using a pre-populated list of likely apps that may generate a response. It's not very accurate but could cross track you if you're visiting some sites with Tor and others with a conventional browser.
