DO BED BUGS TRANSMIT ANY DISEASES?
When we think about unwanted visitors in our comfy homes, bed bugs are the ones that often pop into our heads. These little guys, wearing their reddish-brown outfits, are like night-time ninjas. They sneak around and have a snack while we’re fast asleep. And boy, do they leave their mark! Those itchy, red bumps they give us are like their way of saying, “Thanks for having us over!” But let’s…

Dangers Of Housing Turtles Together
The practice of housing turtles together, often referred to as cohabitation, is a subject that warrants careful consideration by pet owners and enthusiasts. While it may seem convenient or cost-effective to keep multiple turtles in a single enclosure, there are numerous dangers associated with this practice that can compromise the health and well-being of these reptiles. In this article, we will…

Light Pollution Disrupts Mosquitoes' Diapause, Extending Biting Season and West Nile Virus Risk, Study Shows
Photo by Pixabay on Pexels.com A recent study by researchers at Ohio State University has suggested that light pollution in urban areas can have a significant effect on the behavior of mosquitoes that transmit West Nile virus. The study found that exposure to artificial light at night may disrupt the winter dormancy period, known as diapause, for female Northern house mosquitoes, causing them to…

The danger is clear and present: COVID isn’t merely a respiratory illness; it’s a multi-dimensional threat impacting brain function, attacking almost all of the body’s organs, producing elevated risks of all kinds, and weakening our ability to fight off other diseases. Reinfections are thought to produce cumulative risks, and Long COVID is on the rise. Unfortunately, Long COVID is now being considered a long-term chronic illness — something many people will never fully recover from. Dr. Phillip Alvelda, a former program manager in DARPA’s Biological Technologies Office that pioneered the synthetic biology industry and the development of mRNA vaccine technology, is the founder of Medio Labs, a COVID diagnostic testing company. He has stepped forward as a strong critic of government COVID management, accusing health agencies of inadequacy and even deception. Alvelda is pushing for accountability and immediate action to tackle Long COVID and fend off future pandemics with stronger public health strategies. Contrary to public belief, he warns, COVID is not like the flu. New variants evolve much faster, making annual shots inadequate. He believes that if things continue as they are, with new COVID variants emerging and reinfections happening rapidly, the majority of Americans may eventually grapple with some form of Long COVID. Let’s repeat that: At the current rate of infection, most Americans may get Long COVID.
[...]
LP: A recent JAMA study found that US adults with Long COVID are more prone to depression and anxiety – and they’re struggling to afford treatment. Given the virus’s impact on the brain, I guess the link to mental health issues isn’t surprising. PA: There are all kinds of weird things going on that could be related to COVID’s cognitive effects. I’ll give you an example. We’ve noticed since the start of the pandemic that accidents are increasing. A report published by TRIP, a transportation research nonprofit, found that traffic fatalities in California increased by 22% from 2019 to 2022. They also found the likelihood of being killed in a traffic crash increased by 28% over that period. Other data, like studies from the National Highway Traffic Safety Administration, came to similar conclusions, reporting that traffic fatalities hit a 16-year high across the country in 2021. The TRIP report also looked at traffic fatalities on a national level and found that traffic fatalities increased by 19%. LP: What role might COVID play? PA: Research points to the various ways COVID attacks the brain. Some people who have been infected have suffered motor control damage, and that could be a factor in car crashes. News is beginning to emerge about other ways COVID impacts driving. For example, in Ireland, a driver’s COVID-related brain fog was linked to a crash that killed an elderly couple. Damage from COVID could be affecting people who are flying our planes, too. We’ve had pilots that had to quit because they couldn’t control the airplanes anymore. We know that medical events among U.S. military pilots were shown to have risen over 1,700% from 2019 to 2022, which the Pentagon attributes to the virus.
[...]
LP: You’ve criticized the track record of the CDC and the WHO – particularly their stubborn denial that COVID is airborne. PA: They knew the dangers of airborne transmission but refused to admit it for too long. They were warned repeatedly by scientists who studied aerosols. They instituted protections for themselves and for their kids against airborne transmission, but they didn’t tell the rest of us to do that.
[...]
LP: How would you grade Biden on how he’s handled the pandemic? PA: I’d give him an F. In some ways, he fails worse than Trump because more people have actually died from COVID on his watch than on Trump’s, though blame has to be shared with Republican governors and legislators who picked ideological fights opposing things like responsible masking, testing, vaccination, and ventilation improvements for partisan reasons. Biden’s administration has continued to promote the false idea that the vaccine is all that is needed, perpetuating the notion that the pandemic is over and you don’t need to do anything about it. Biden stopped the funding for surveillance and he stopped the funding for renewing vaccine advancement research. Trump allowed 400,000 people to die unnecessarily. The Biden administration policies have allowed more than 800,000 to 900,000 and counting.
[...]
LP: The situation with bird flu is certainly getting more concerning with the CDC confirming that a third person in the U.S. has tested positive after being exposed to infected cows. PA: Unfortunately, we’re repeating many of the same mistakes because we now know that the bird flu has made the jump to several species. The most important one now, of course, is the dairy cows. The dairy farmers have been refusing to let the government come in and inspect and test the cows. A team from Ohio State tested milk from a supermarket and found that 50% of the milk they tested was positive for bird flu viral particles.
[...]
PA: There’s a serious risk now in allowing the virus to freely evolve within the cow population. Each cow acts as a breeding ground for countless genetic mutations, potentially leading to strains capable of jumping to other species. If any of those countless genetic experiments within each cow prove successful in developing a strain transmissible to humans, we could face another pandemic – only this one could have a 58% death rate. Did you see the movie “Contagion?” It was remarkably accurate in its apocalyptic nature. And that virus only had a 20% death rate. If the bird flu makes the jump to human-to-human transition with even half of its current lethality, that would be disastrous.

if you ever want to dip your toes into the more creepy side, in the episode "a health of information" a disease called swamp fever apparently turns living ponies into trees!! it always freaked me out, and since it was in the later seasons, it just wasn't developed upon (of course :P) there's a screenshot of one of the doctor ponies holding up a book that shows the cycle of transformation-- the stage where they've still got limb-like roots is so so creepy!!
HEY WHAT???? HEY WHAT. WHAT THE HECK IS THIS
#ask#a health of information#oohhogh the bees are immune to a disease that affects ponies!#YEAH THATS HOW DISEASES WORK#VERY FEW ARE ACTUALLY TRANSMISSABLE BETWEEN SPECIES#MUCH LESS BETWEEN PHYLUMS!!?!?!?!??!?!??!#ssg swamp fever

UH OH
In college I studied conservation medicine and zoonotic diseases, and this is not good.
"A new study has determined that the COVID-19 virus is widespread amongst wildlife in the United States. SARS-CoV-2, the virus that causes COVID-19, was recently detected in six common backyard species. Additionally, antibodies indicating prior exposure to the virus were found in five species. Depending upon the species, exposure rates ranged from 40-60%."
And this research was done in my state. Great.
From animal to human and back to animal. This does not bode well for us.

CTVT and a weird niche theory I fell down the rabbit hole about - giant transforming retroviruses???
This is a story about how a single line on a wikipedia page sent me down a rabbit hole of finding one scientist's fringe theory that's juuuust plausible enough to make me question everything while almost certainly being absolute fucking bunk.
Some background
So, on parts of tumblr at least we all know about Canine Transmissible Venereal Tumour, aka The Immortal Cancer Dog. For those who don't know, it's a cancer dogs get, usually on their junk, that unlike most other cancers, isn't made up of their own cells. The cells are actually all descended from this one dog or wolf that lived like 11,000 years ago and are, arguably, all technically that one dog. A dog that became a single-celled infectious disease.
We have a wealth of genetic, histological and observational evidence for this. As in, we know it what population of canids it came from, we know it's got a weird chromosomal structure compared to normal dogs, we know it's genetically distinct from the hosts. We also know it's not the only one out there: There's a similar thing in Syrian hamsters and also the famous Tasmanian Devil Facial Tumour Disease (DFTD).
Which made me pause when I was reading something on wikipedia about the devil facial tumour and saw a line mentioning that it was now known to be caused by a giant virus, much like CTVT. Which...huh? Oh I hadn't heard that afore.
Giant viruses
Ok so giant viruses are a thing and they're fuckin cool. They're a relatively recent discovery and comparatively huge, i.e. bigger than a bunch of bacteria. They were only discovered in 1981 and we still don't know an enormous amount about them but they're big and have large genomes and because of the way viruses are they're not easy to detect unless you're specifically looking for them.
They show up under microscopy (sometimes) and you can find them with genetic probes but you gotta already be looking for them to see that really. Current research though basically says they're more common than we think, just overlooked, and there's software out there that scans through genomic data to find sequences that might indicate their presence. There's even a possibility that one group might be involved in some cases of pneumonia in humans, though I need to stress that that's extremely not confirmed right now.
The "wait, what?" moment
So I mentioned that it was a line in the wiki article for DFTD that had me going "wait, really?", the line in question was this:
A study found evidence for an infectious agent resembling a giant virus that was capable of turning heathy cells into cancer cells. It was found to be a huge retrovirus with similar viruses being found in human and canine cancer cells.
Big If True.
So of course I check the source, which was a 2020 paper by Lusi et al. titled "A transforming giant virus discovered in Canine Transmissible Venereal Tumour: Stray dogs and Tasmanian devils opening the door to a preventive cancer vaccine".
Hang on, CTVT not DFTD? This is where some alarm bells went off because uh, as mentioned at the start, we know a shit ton about CTVT. Including the fact that it's all one specific dog. Which doesn't fit at all with the idea that it's caused by a virus transforming host cells into cancer cells.
So what fucking gives? What is this research that fully overturns decades of pretty conclusive research to the contrary?
Is this another case of Dr Barbara McClintock? Who spent decades being ridiculed by the scientific community over her wild theory that was, in fact, 100% right even if it seemed to fly in the fact of all prior evidence?
Or is this a Dr Donald I. Williamson situation wherein a scientist with appropriate training is just wildly but extremely vehemently wrong?
#science#genetics#cancer#canine transmissible venereal tumour#devil facial tumour disease#niche science#I'm breaking this up into several sections for readability#stay tuned for more#also feel free to ask any questions about stuff#I'll provide links to things as well but I know tumblr can bury posts with certain links in and idk if researchgate counts

thinking about the guy the other day who said "i hated wearing a mask so much during covid i'm never wearing a mask again i don't care if other people get sick" like he said it kind of jokingly but Holy Shit
#we spent a whole two years finding ways to easily prevent disease transmission and now no one wants to use them. are you crazy#<- sorry i'm kind of a germaphobe and it makes me really really annoying. but also you should be masking if you're sick?? fucking hello??#.txt
