Finding out that buy and large what people mean when they say "it's dangerous to reheat rice!!" is that if rice is held at a tepid temperature for an extended period of time it tends to grow cultures that can cause food poisoning. A fact that is true about pretty much everything.

18 hours difference of bacteria growth
Tumblr media
How much can Staphylococcus aureus bacteria grow in less than a day? I add a few drops of bacteria into a fresh medium (basically a meat bouillon soup) and after 18 hours I count tens of billions bacteria per milliliter. Literally, today I had 8x10^10 bacteria/ml. They grow like crazy when given the chance.
For the next 24 hours, I let them bath in antibiotics. Hehe!

The sardonic, reductionist headline here could be "Scientists finally figured out why you get more colds in winter: bEcAuSe iT's CoLd!"—but the actual science involved here is both interesting, and potentially very relevant to everyday life and especially the immunocompromised:
It turns out the cold air itself damages the immune response occurring in the nose. [...] In fact, reducing the temperature inside the nose by as little as 9 degrees Fahrenheit (5 degrees Celsius) kills nearly 50% of the billions of virus and bacteria-fighting cells in the nostrils, according to the study published Tuesday in The Journal of Allergy and Clinical Immunology. “Cold air is associated with increased viral infection because you’ve essentially lost half of your immunity just by that small drop in temperature,” said rhinologist Dr. Benjamin Bleier, director of otolaryngology at Massachusetts Eye and Ear and an associate professor at Harvard Medical School in Boston.
Want to avoid catching or spreading respiratory viruses like CoVid-19, RSV, influenza, or a common cold? Mask up, please, but also bundle up! Wrap up in a scarf, wear a balaclava, and just generally keep your face warm. There's no single magic solution, but that's not a reason to do nothing. Rather, it's a reason to take several simple precautions that help avoid the spread of disease and protect those around you. (I can't tell you how much "this isn't 100% effective so I shouldn't do it at all" frustrates me.)
Oh, and #knitblr? This is your time to shine.

genuine question- how do you feel about vaccination?
Very pro. I’ve gotten every vaccine I’ve ever been offered. I’m behind on my flu shot this year but that’s just because they keep doing the work clinics on days when I’m either not there or working through lunch. Our immune systems are ticking time bombs that are always looking for an excuse to kill us and so far all available evidence suggests that exposing them to things via vaccine reduces the rate of autoimmune issues due to that specific virus or bacteria later, in addition to decreasing frequency and severity of infection. The shingles vaccine may even decrease risk of dementia, which is HUGE.

The knowledge of some common plants
Since many people don't know most of the plants around them, this is information on some plants that are commonly seen in many places throughout the world
Tumblr media
This is Lamium purpureum, also called Purple Deadnettle.
It's called deadnettle because it looks like a nettle but it doesn't sting you
This plant is a winter annual—it grows its leaves in the fall, lasts through the winter, and blooms and dies in the spring
Its pollen is reddish orange. If you see bees with their heads stained reddish orange, it is likely because they have visited Purple Deadnettle
Tumblr media
This is Trifolium repens, white clover
It is a legume (belongs to the bean family) and fixes nitrogen using symbiosis with bacteria that live in little nodules on its roots, fertilizing the soil
It is a good companion plant for the other members of a lawn or garden since it is tough, adaptable, and improves soil quality. According to my professor it used to be in lawn mixes, until chemical companies wanted to sell a new herbicide that would kill broadleaved plants and spare grass, and it was slandered as a weed :(
It is native only to Europe and Central Asia, but in the lawns they are doing more good than harm most places
Honeybees love to visit clover
Four-leaf clovers are said to be lucky
Tumblr media Tumblr media
This is Achillea millefolium, Common Yarrow
It has had a relationship with humans since Neanderthals were around, at least 60,000 years, since Neanderthals have been found buried with Yarrow
Its leaves have been used to stop bleeding throughout history, and its scientific name comes from how Achilles was said to have used Yarrow to stop the blood from the wounds of his soldiers. A leaf rolled into a ball has been used to stop nosebleeds
It is a native species all throughout Eurasia and North America
Tumblr media
This is Cichorium intybus, known as Chicory
The leaves look a lot like dandelion leaves, until in mid-spring when it begins growing a woody green stem straight up into the air
Like many other weeds, it has a symbiotic relationship with humans, existing in a mix of domesticated or partially domesticated and wild populations
It is native to Eurasia, but widespread in North America on roadsides and disturbed places, where it descended from cultivated plants
Its root contains large amounts of inulin, which is used as a sweetener and fiber supplement (if you look at the ingredients on the granola bars that have extra fiber, they usually are partly made of chicory root) and has also been used as a coffee substitute
A large variety of bees like to feed upon it
Tumblr media Tumblr media
This is Phytolacca americana, known as Pokeweed
It is easily identified by its huge leaves and its waxy, bright magenta stem
It can grow more than nine feet tall from a sprout in a single summer!
If you squish the berries, the juice inside is a shocking magenta that is so bright it almost burns your eyes. For this reason many Native American people used it for pink and purple dye.
It is a heavy metal hyperaccumulator, particularly good for removing cadmium from the soil
All parts of the plant are poisonous and will make you very sick if you eat them, however if the leaves are picked when very young and boiled 3 times, changing out the water each time, they can be eaten, and this is a traditional food in the rural American Southeast, but I don't want to chance it
British people have introduced it as a pretty, exotic ornamental plant. I think that is very funny considering that here it is a weed associated with places where poor people live, but maybe they're right and I need to look closer to see the beauty.
If you see magenta stains in bird poop it is because they ate pokeweed berries- birds can safely eat the berries whereas humans cannot
Tumblr media Tumblr media
This is Plantago lanceolata, Ribwort Plantain
It grows in heavily disturbed soils, in fact it is considered an indicator of agricultural activity. It is successful in the poorest, heaviest and most compacted soil.
The leaves, seeds, and flower heads are said to be edible but the leaves are really stringy unless they are very young. Of course, it is important to be careful when eating wild plants, and make sure you have identified the plant correctly and the soil is not contaminated
I have also heard the strings in the leaves can be extracted and used for textile purposes
and that's some common plants you might often see throughout the world

Okay, how ridiculous are the comments on food shorts on FB? Literally any time a girl with false nails is making something, half the comments are about how gross she is. For...making food with long nails???
Or the people who tell girls (even without false nails) to wear gloves when they're cooking. If they don't they're disgusting and nobody should ever eat their food. Literal 🤮emojis.
Who in the actual fuck wears gloves to cook at home? How do they think women with false nails eat or feed their families? Gloves and short, polish-free nails are only necessary if you're working in a commercial/industrial environment. Because you're exposed to a wide variety of germs, you're preparing food for a longer period of time, there's a much greater risk of cross contamination and you don't want to endanger the public.
Are there actual people these days who legit put on gloves to cook for themselves in their own homes???

Look. I have literally no horse in this race when it comes to the WGA/SAG Hollywood strike. I do not watch enough TV or movies to be affected and I’m not a part of the industry. I really haven’t cared.
As a lawyer and orchardist, however, I am now utterly entranced by the fact that some Universal Studios exec thought it was a good idea to cut down city-owned trees in the middle of summer.
There is no way to get around the absolute clusterfuck they have brought down upon themselves.
First, the ownership question. These trees are not owned by Universal. They’re the City of Los Angeles’ trees. That means the responsibility, and the right, to maintain them belongs to the city government. If you want to touch city property like that, you better have their permission. If not, you’re looking at anything from fines, to replacement/maintenance costs, to jail time.
Now, I don’t know LA, and I’m not licensed in California, but a lot of cities also require permits for any massive trimming like that that can affect public property (like the roads and sidewalks).
Second, they have zero excuses that can even remotely minimize the trouble they’re in. Anything that justifies that kind of pruning at this time of year would have likely required the full removal and destruction of the trees.
Because that level of pruning? You don’t do that in summer. You absolutely do not do that in summer unless the trees are dying or infested with something. Why? Because summer is healthy growth time. Summer is when your trees need all the energy they can get so they can grow and strengthen their branches and roots.
It’s also when they’re susceptible to diseases. Various bacteria, fungi, and insects strike during the summer and can cause severe damage. By trimming those trees so severely, not only are there a ton of gapping wounds for diseases to enter the tree, they’re now stressed by trying to replace that lost growth, which makes it even harder for them to survive any further damage.
Basically, Universal Studios might end up accidentally killing the trees. Which will make everything so much worse.
So, yeah. Now I’m invested.

In photos of 2023’s World Economic Forum- or Davos as it is commonly called, after the Swiss resort town where it annually occurs- you might not notice the HEPA filters. They’re in the background, unobtrusive and unremarked upon, quietly cleansing the air of viruses and bacteria. You wouldn’t know- not unless you asked- that every attendee was PCR tested before entering the forum, or that in the case of a positive test, access was automatically, electronically, revoked. And if you happened to get a glimpse of the strange blue lights overhead, you could reasonably assume that their glow was simply a modern aesthetic choice, not the calming buzz of cutting edge Far UVC technology- demonstrated to kill microbes in the air.
It’s hard to square this information with the public narrative about COVID, isn’t it? President Biden has called the pandemic “over”. The New York Times recently claimed that “the risk of Covid is similar to that of the flu” in an article about “hold outs” that are annoyingly refusing to accept continual reinfection as their “new normal”. Yet, this week the richest people in the world are taking common sense, easy- but strict- precautions to ensure they don’t catch Covid-19 at Davos.
These common sense, easy precautions include high-quality ventiliation, use of Far UVC-lighting technology, and PCR testing. You’ll also see some masks at Davos, but generally, the testing + air filtration protocol seems to be effective at preventing the kind of super-spreader events most of us are now accustomed to attending.
It seems unlikely to me that a New York Times reporter will follow the super-rich around like David Attenborough on safari, the way one of their employees did when they profiled middle-class maskers last month. I doubt they will write “family members and friends can get a little exasperated by the hyper-concern” about the assembled Prime Ministers, Presidents and CEOs in Switzerland. After all, these are important people. The kind of people who merit high-quality ventilation. The kind of people who deserve accurate tests.
Why is the media so hellbent on portraying simple, scientifically proven measures like high-quality ventilation as ridiculous and unnecessary as hundreds of people continue to die daily here in the US?
Why is the public accepting a “new normal” where we are expected to get infected over and over and over again, at work events with zero precautions, on airplanes with no masks, and at social dinners trying to approximate our 2019 normal?
We deserve better. We deserve to be #DavosSafe as the hashtag going around on twitter puts it. Your children deserve to be treated with the care that world leaders are treating each other. Your family deserves to be protected from the disease which is still- unlike the flu- the third leading cause of death in the US. We don’t deserve to be shoved back into poorly ventilated workplaces while our politicians and press assure us that only crazy people would demand to breathe clean air.
Clean water and clean food are rights we fought for; we have regulatory bodies that ensure we aren’t exposed to pathogens via our water supply nor our food. In 1854, John Snow famously conducted his Broad Street Pump study in London and demonstrated that cholera was water-bourne; however, it took decades for our public policy to catch up with our scientific knowledge.
A public health case study published by the NBCI describes the years that followed:
The first use of chlorine as a disinfectant for water facilities was in 1897 in England. The first use of this method for municipal water facilities in the United States was in Jersey City, New Jersey, and Chicago, Illinois, in 1915. Other cities followed and the use of chlorination as standard treatment for water disinfection rapidly grew. During the 20th century, death rates from waterborne diseases decreased significantly, and although other additional factors contributed to the general improvements in health (such as sanitation, improved quality of life, and nutrition), the improvement of water quality was, without doubt, a major reason.
Forty-three years passed from the initial demonstration that pathogens were being spread via water, and public action and regulation to halt disease.
Can you imagine, in the 1890s, being somebody who argued against cleaning the water?
Can you imagine, in those years of plentiful cholera, calling the people who demanded shit-free water “hold outs”?
One thing COVID realists are accused of is being “doomsayers” and “fearmongers,” so let me share a dose of optimism about the future with you. When we choose- whenever we choose- to get COVID under control, there’s an exciting new world awaiting us. One, not only without constant COVID reinfection, but where our kids can grow up free of colds, flus, RSV, and many other common bugs. And no, contrary to what you may have heard, staying healthy (shockingly enough) is not bad for children!
Once we choose to institute ventilation standards and introduce new technologies like Far UVC lighting- and embrace masking as an easy, kind, and useful tool to control outbreaks- we can bring every nasty airborne pathogen under control the way we did cholera. We didn’t have the science before; now we do. (I mean that quite literally; I can’t recommend enough the linked Wired article cataloguing the long journey to establishing that Covid is, indeed, airborne).
We face a stark choice; down one road, the one with zero infrastructure upgrades, no air quality regulations, and Covid safety only for those who can afford it, you and your family will get Covid this year. You will get Covid next year. You will continue to get Covid over and over and over again, as the health problems - like cardiac damage, viral persistance, and immune system dysfunction- continue to build up. (The billionaires, of course, will not).
Down the other road, we quite simply treat ourselves the way Davos would. We engage with what the science is telling us and we build a safer, better world for our kids. We embrace the lessons this pandemic is teaching us, and let go of things we now know are harming people. We stop clinging desperately to the idea that 2019 will come back if we just get the virus one more time, and we come together to achieve what we’ve been told is impossible: elimination.
The economic elite thrive on our divisiveness and blame casting. They don’t mind that we’re calling each other names, engaging in racial stereotyping, or leaving disabled people to die, so long as we keep their machine running. But we can choose to stop throwing blame at each other, and direct it where it belongs: at the powerful people who’ve left us to suffer, at the politicians who are whipping people into a frenzy over masks instead of over our millions of dead, at the talking heads on TV that work so hard to convince us: you want to get sick. It’s better than being a *weirdo* or a *hold out*.
We needn’t wait 43 years to redirect our energies. France and Belgium have already introduced new air quality standards, and DIY projects to build Corsi-Rosenthal boxes for schools and healthcare settings have popped up around the country. We have the science, we have the technology. All we need now is the political will and the solidarity to truly end the pandemic- the kind of solidarity the super rich always show with one another.
The billionaires at Davos don’t accept continual Covid reinfection. They demand better. It’s time we demand better too.
