>diseases are caused by bad air, there are no microscopic organisms
>the high IQ STEMchuds are straight up laughing at what the philosophy teacher says half the time.
Brutal.
there isn't a good word because the distinctions are pretty complicated between the three still pretty unique tiers of limitations
basically this is why da Jews are actually kind of based and redpilled and not just malicious because whatever for no good reason and christianity is kind of like building towers instead of studying earthquakes and stuff first
generally eastern cultures don't do stuff just because they could and there are like 3 archetypes of the dumb white guys that have no idea wtf they're doing and lots of names for people who filled those roles
basically this is post enlightenment hellenism and it should be taught alongside english grammer in like 6th grade then they let people choose to stop going to school after that

>Although the overall proportion of those experiencing a psychiatric encounter was similar between the vaginoplasty and phalloplasty groups, suicide attempts were more common in the vaginoplasty group (4.4% vs. 1.7%, p=0.033). The rate of a psychiatric encounter occurring after surgery if an episode prior surgery occurred was 33.9% and 26.5% for the vaginoplasty and phalloplasty groups.

There are differences in Race when it comes to medicine. White People are more prone to skin cancer than any other race due to a lack of melanin in their skin. Black people are at higher risks for high blood pressure, certain types of cancers and diabetes. Asians are at higher risks for liver disease than other races. Mixed race individuals are more likely to have these risks offset due to being biracial or multiracial but in some cases their risks of diseases prevalent in their heritage might be higher. Just like there are differences in biological sexes for treatment. Some humans like the Badjao or the Tibetans have evolved higher lung capacity compared to the average human.
So we have all these physical differences, affecting even diseases and medical treatment but somehow mentally we are all the same? That's kinda fishy no?
How come scientists never discovered this until recently?
Seems like it should be big news, but they never talk about it.
Why does this keep on happening?
So there you have it. Couldn’t be any more official. Science now believes women stay at the same level of fertility throughout their lives.
Science is retarded and clownishly evil. Smash science. Kill science.

>The "hallmarks of cancer" were proposed by Hanahan and Weinberg (2000) as a group of biological competencies that human cells attain as they progress from normalcy to neoplastic transformation. These competencies include self-sufficiency in proliferative signaling, insensitivity to growth-suppressive signals and immune surveillance, the ability to evade cell death, enabling replicative immortality, reprogramming energy metabolism, inducing angiogenesis, and activating tissue invasion and metastasis. Underlying these competencies are genome instability, which expedites their acquisition, and inflammation, which fosters their function(s). Additionally, cancer exhibits another dimension of complexity: a heterogeneous repertoire of infiltrating and resident host cells, secreted factors, and extracellular matrix, known as the tumor microenvironment, that through a dynamic and reciprocal relationship with cancer cells supports immortality, local invasion, and metastatic dissemination.

Human and chimp have more:
-cytosine (C)
-guanine (G), but this is less noticeable than C
than insects/spiders
However these arthropods have more thymine (T) and adenine (A) than humans or monkeys do

Just how delicate and precious is life really? Obviously we have no way of going back in time or looking at life from beginning to end in its full totality.
Apparently not!

RIP Vaxxies
We tried to warn you.
What astrophysical evidence would even possibly count as evidence that the universe is infinitely old? My understanding of the history of western thought is presuming the universe has/has no beginning is fundamentally a theological or metaphysical concern. No amount of finite evidence will ever confirm one over the other because the finite age can always be pushed back one layer of explanation so as to make sense with all of the observations made. What is the consensus on this dilemma in the theoretical physicist community? The way I see it is science simply has no say on whether the universe began to exist, unless scientists inject some metaphysical philosophy into their own theory.

"Cannabis is involved in approximately 50% of psychosis, schizophrenia, and schizophreniform psychosis cases"
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3927252/
"In one recent study that followed nearly 2,000 teenagers as they became young adults, young people who smoked marijuana at least five times were twice as likely to have developed psychosis over the next 10 years as those who didn’t smoke pot."
"One of the best-known studies followed nearly 50,000 young Swedish soldiers for 15 years. Those who had smoked marijuana at least once were more than twice as likely to develop schizophrenia as those who had never smoked pot. The heaviest users (who said they used marijuana more than 50 times) were 6x as likely to develop schizophrenia as the nonsmokers."

Daily weed use was associated with increased odds of psychotic disorder compared with never users, increasing to nearly 5x increased odds for daily use of high-potency types of cannabis. The PAFs calculated indicated that if high-potency cannabis were no longer available, 12% of cases of first-episode psychosis could be prevented across the 11 sites, rising to 30% in London and 50% in Amsterdam

>Stephen Schneider of the National Center for Atmospheric Research described the scientists’ dilemma this way:
>“On the one hand, as scientists, we are ethically bound to the scientific method, in effect promising to tell the truth, the whole truth, and nothing but—which means that we must include all the doubts, the caveats, the ifs, ands, and buts. On the other hand, we are not just scientists but human beings as well.
>And like most people we’d like to see the world a better place, which in this context translates into our working to reduce the risk of potentially disastrous climatic change. To do that we need to get some broad-based support, to capture the public’s imagination. That, of course, entails getting loads of media coverage. So we have to offer up scary scenarios, make simplified, dramatic statements, and make little mention of any doubts we might have. This ‘double ethical bind’ we frequently find ourselves in cannot be solved by any formula. Each of us has to decide what the right balance is between being effective and being honest.”
Science is in salvageable and scientists are net negative impact 105 iq assburgers thinking they’re much smarter than they really are. They also believe they’re at the end of history at any given moment, again because of midwitism. This allows them to justify any atrocity, and never consider any evidence outside their established narrative.

Construction and validation of a scale for assessing critical social justice attitudes
https://onlinelibrary.wiley.com/doi/10.1111/sjop.13018
>DISCUSSION
>The studies also assessed how having critical social justice attitudes relates to well-being variables. Many authors have previously linked critical social justice attitudes to poorer mental well-being in their work implicitly, but have not studied them directly (e.g., Lukianoff & Haidt, 2018). In our samples (Study 1 and Study 2), having high CSJAS (critical social justice attitude scale) scores was linked to anxiety, depression, and a lack of happiness. However, Study 2 indicated that this lower level of mental well-being was mostly associated with being on the political left and not specifically with having a high CSJAS score. The association between lower mental health and supporting the political left is in line with what other studies have found prior to this one (Bernardi, 2021; Gimbrone et al., 2022).

Background: Symptoms of primary HIV infection, including fever, rash, and headache, are nonspecific and are often described as flu-like. COVID-19 vaccination side effects, such as fever, which occur in up to 10% of people following COVID-19 vaccination, can make the diagnosis of acute HIV infection even more challenging.
Case presentation: A 26-year-old man presented with fever and headache following COVID-19 vaccination. The symptoms were initially thought to be vaccine side effects. A diagnostic workup was conducted due to persisting fever and headache > 72 h following vaccination, and he was diagnosed with Fiebig stage II acute HIV infection, 3 weeks after having unprotected anal intercourse with another man.
Conclusion: Thorough anamnesis is key to estimating the individual risk of primary HIV infection, in patients presenting with flu-like symptoms. Early diagnosis and initiation of antiretroviral therapy is associated with better prognosis and limits transmission of the disease.
>Effects of elevated CO2 on resistant and susceptible rice cultivar and its primary host, brown planthopper
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8076292/
>The elevated CO2 (eCO2) has positive response on plant growth and negative response on insect pests. As a contemplation, the feeding pattern of the brown plant hopper, Nilaparvata lugens Stål on susceptible and resistant rice cultivars and their growth rates exposed to eCO2 conditions were analyzed. The eCO2 treatment showed significant differences in percentage of emergence and rice biomass that were consistent across the rice cultivars, when compared to the ambient conditions. Similarly, increase in carbon and decrese in nitrogen ratio of leaves and alterations in defensive peroxidase enzyme levels were observed, but was non‐linear among the cultivars tested. Lower survivorship and nutritional indices of N. lugens were observed in conditions of eCO2 levels over ambient conditions. Results were nonlinear in manner. We conclude that the plant carbon accumulation increased due to eCO2, causing physiological changes that decreased nitrogen content. Similarly, eCO2 increased insect feeding, and did alter other variables such as their biology or reproduction.
Is soience really that useless and impotent?

Cherry blossoms finally burst into bloom in Tokyo on Friday after heavy rain in the morning, marking the latest blooming in over a decade.
The declaration of the blooming made by the Meteorological Agency came 15 days later than last year and five days later than in an average year. Private forecasters had also expected this year's bloom to come much earlier.
Friday’s blooming is the latest in Tokyo since 2012, when cherry blossoms were declared to have blossomed on March 31, according to the agency.
Cherry blossom forecasting is big business in Japan. As early as in January, companies start to issue forecasts for when cherry blossoms will first bloom and reach their peak.
The weather agency, which began forecasting the annual bloom in 1955, sets a government standard for observing cherry blossom trees. For consistency, the meteorological agency only uses data gathered from the Somei-Yoshino variety, which produces pale pink blossoms.
That means no trigonometry, brainlets.
When you presume that the standard model is correct, and that dark matter is needed for it to work, you're way more likely to just point at the few bits of evidence for dark matter detection and ignore all the failed attempts to detect it.
You've already decided on the conclusion beforehand. The experiments and research don't matter.

It was then stated that the appearent black volume around it is the part past the singularity where light cant escape (it kinda makes sense)
What doesn't make sense to me is how matter gets so compressed that it loses its spacial dimension.
Before reading this i thought that a black hole was just made of something like atoms put side by side by forces stronger than the repulsions between different atoms's electrons, but following this idea the black hole should have a small but surely existent volume.
So why does matter lose its spacial dimensions?

A fungus like jock itch, it would be like a grass.
Which grows on the skin.
If I use peroxyde water is like burning it.
But the fungus will grow again, like grass.
If I keep using peroxyde water every day, It will regrow, but lesser every time.
Eventually the skin regrows, and the fungus is simply expelled because the skin would have entirelly being replaced, like cutting a fungus area in a bannana.
This would explain why is so hard to get rid off?
Is my idea more or less on the right path?

if you love stats, weird numbers and counterintutive science, this is your general. Because one of the things with statistics is that nothing ever seems to be what it tries to show you on a first glance or glimpse. Doesn't matter if you are a seasoned professional, NEET or some disgruntled grad student. All are welcome.
Some people may not like it if you try to make them do your homework, others won't care and will just help you. Let's discuss theories together, ask questions and try to meme a little about this field.
in the previous thread we discussed why Julia has promise but is not delivering. How some people still use Matlab but hate it.
So, grab your favorite statistical software, dust off your textbooks, and join me in this exciting journey through the world of /psg/ - Probability and Statistics General! Let's embark on this adventure together and unravel the mysteries of data one statistical concept at a time.

What I want to know is whether it is practically possible for sunglasses which block UVA light to fail to block UVB light. As far as I can tell, the materials which typically are said to have this property are metallic pigments that are used in sunblock.
What methods do sunglass manufacturers use to block UV light, and how likely do you believe it is, given these methods, that sunglasses bought online might have the ability to block UVA but not UVB?

The Riemann Zeta function, (\zeta(s)), is defined for (\text{Re}(s) > 1) by the absolutely convergent series:
[
\zeta(s) = \sum_{n=1}^\infty \frac{1}{n^s}
]
and extended to the rest of the complex plane (except (s = 1)) via analytic continuation. The functional equation for (\zeta(s)) is central in its analysis:
[
\zeta(s) = 2^s \pi^{s-1} \sin\left(\frac{\pi s}{2}\right) \Gamma(1-s) \zeta(1-s)
]
The Riemann Hypothesis asserts that all non-trivial zeros of (\zeta(s)) lie on the critical line (\text{Re}(s) = \frac{1}{2}).
