We Were Badly Misled About the Event That Changed Our Lives

Since scientists began playing around with dangerous pathogens in laboratories, the world has experienced four or five pandemics, depending on how you count. One of them, the 1977 Russian flu, was almost certainly sparked by a research mishap. Some Western scientists quickly suspected the odd virus had resided in a lab freezer for a couple of decades, but they kept mostly quiet for fear of ruffling feathers.

Yet in 2020, when people started speculating that a laboratory accident might have been the spark that started the Covid-19 pandemic, they were treated like kooks and cranks. Many public health officials and prominent scientists dismissed the idea as a conspiracy theory, insisting that the virus had emerged from animals in a seafood market in Wuhan, China. And when a nonprofit called EcoHealth Alliance lost a grant because it was planning to conduct risky research into bat viruses with the Wuhan Institute of Virology â" research that, if conducted with lax safety standards, could have resulted in a dangerous pathogen leaking out into the world â" no fewer than 77 Nobel laureates and 31 scientific societies lined up to defend the organization.

So the Wuhan research was totally safe, and the pandemic was definitely caused by natural transmission â" it certainly seemed like consensus.

We have since learned, however, that to promote the appearance of consensus, some officials and scientists hid or understated crucial facts, misled at least one reporter, orchestrated campaigns of supposedly independent voices and even compared notes about how to hide their communications in order to keep the public from hearing the whole story. And as for that Wuhan laboratoryâ(TM)s research, the details that have since emerged show that safety precautions might have been terrifyingly lax.

Submission + - Another large Black hole in "our" Galaxy (arxiv.org)

RockDoctor writes: A recent paper on ArXiv reports a novel idea about the central regions of "our" galaxy.

Remember the hoopla a few years ago about radio-astronomical observations producing an "image" of our central black hole — or rather, an image of the accretion disc around the black hole — long designated by astronomers as "Sagittarius A*" (or SGR-A*)? If you remember the image published then, one thing should be striking — it's not very symmetrical. If you think about viewing a spinning object, then you'd expect to see something with a "mirror" symmetry plane where we would see the rotation axis (if someone had marked it). If anything, that published image has three bright spots on a fainter ring. And the spots are not even approximately the same brightness.

This paper suggests that the image we see is the result of the light (radio waves) from SGR-A* being "lensed" by another black hole, near (but not quite on) the line of sight between SGR-A* and us. By various modelling approaches, they then refine this idea to a "best-fit" of a black hole with mass around 1000 times the Sun, orbiting between the distance of the closest-observed star to SGR-A* ("S2" — most imaginative name, ever!), and around 10 times that distance. That's far enough to make a strong interaction with "S2" unlikely within the lifetime of S2 before it's accretion onto SGR-A*.)

The region around SGR-A* is crowded. Within 25 parsecs (~80 light years, the distance to Regulus [in the constellation Leo] or Merak [in the Great Bear]) there is around 4 times more mass in several millions of "normal" stars than in the SGR-A* black hole. Finding a large (not "super massive") black hole in such a concentration of matter shouldn't surprise anyone.

This proposed black hole is larger than anything which has been detected by gravitational waves (yet) ; but not immensely larger — only a factor of 15 or so. (The authors also anticipate the "what about these big black holes spiralling together?" question : quote "and the amplitude of gravitational waves generated by the binary black holes is negligible.")

Being so close to SGR-A*, the proposed black hole is likely to be moving rapidly across our line of sight. At the distance of "S2" it's orbital period would be around 26 years (but the "new" black hole is probably further out than than that). Which might be an explanation for some of the variability and "flickering" reported for SGR-A* ever since it's discovery.

As always, more observations are needed. Which, for SGR-A* are frequently being taken, so improving (or ruling out) this explanation should happen fairly quickly. But it's a very interesting, and fun, idea.

University of Michigan Study Advocates Ban of Facial Recognition in Schools (venturebeat.com) 18

University of Michigan researchers recently published a study showing facial recognition technology in schools has limited efficacy and presents a number of serious problems. From a report: The research was led by Shobita Parthasarathy, director of the university's Science, Technology, and Public Policy (STPP) program, and finds the technology isn't just ill-suited to security purposes, it can actively promote racial discrimination, normalize surveillance, and erode privacy while marginalizing gender nonconforming students. The study follows the New York legislature's passage of a moratorium on the use of facial recognition and other forms of biometric identification in schools until 2022. The bill, a response to the Lockport City School District launching a facial recognition system, was among the first in the nation to explicitly regulate or ban use of the technology in schools. That development came after companies including Amazon, IBM, and Microsoft halted or ended the sale of facial recognition products in response to the first wave of Black Lives Matter protests in the U.S.

I've also seen this misrepresented already. "SARS-CoV-2 RNA was identified on a variety of surfaces in cabins of both symptomatic & asymptomatic infected passengers up to 17 days after cabins were vacated on the DP but before disinfection procedures had been conducted"

Say it with me: *viral RNA doesn't necessarily mean live virus was present.* Now you're going to see "coronavirus can live on surfaces for 17 days!" over and over, but we don't know that based on this study and for those using live virus, it's much shorter.

It's not supposed to be "impressive", and if the amount of plastic in the oceans has certain environmental consequences, the Earth doesn't do per capita calculations when deciding environmental impacts.

But yes, by all means: let's keep focusing on straws and bags, ignoring China and India on greenhouse gas emissions -- because they are "developing", or they have more people -- and rejecting nuclear power.

By analyzing the waste found in the rivers and surrounding landscape, researchers were able to estimate that just 10 river systems carry 90% of the plastic that ends up in the ocean.

Eight of them are in Asia: the Yangtze; Indus; Yellow; Hai He; Ganges; Pearl; Amur; Mekong; and two in Africa â" the Nile and the Niger.
