World CAN Vaccinate Against COVID Quickly In 2021 With COVAX + Doses Already Secured By Wealthy Countries & Technology Transfer

Mar 24 2021 - 10:03

We are getting scary stories claiming that though the US / UK / Israel / EU / UAE etc will be vaccinated fast, all adults well before the summert, that the rest of the world will not be vaccinated until 2024 or some such date. But the world has already secured enough doses for 5.45 billion people in 2021 with many more on their way. The reason we have so many doses available for 2021 is that wealthy countries have pre-ordered enough doses for all their citizens many times over They did this as a precaution, because just about all the vaccines succeeded and they expected only a few to succeed.

So why are people saying that the rest of the world won’t be vacinated until 2024?

Churches Increase COVID-19 Vaccine Uptake Among African-Americans

Mar 23 2021 - 16:03
Pilot results from San Bernardino County, California, where crime is prevalent and distrust in government high, found that religion may be key to COVID-19 vaccine uptake. Focused education efforts and an on-site mobile clinic in Black church parking lots resulted in the vaccinations of 417 people, 84% of whom were Black.

Results also showed an increase in Black attendance of mass vaccination clinics to 3.6% of total patients, up from 3%, in the week following asking Black churches and clergy to help in COVID-19 vaccination education and distribution.

A Gesture Is Worth A Thousand Words?

Mar 23 2021 - 14:03
What sets human communication apart from lower animals is its compositionality, which means that units of meaning can be combined and new meanings can be constructed. The words "blue" and "car" have their own meanings but combined there is a new content, i.e., a car that is blue.

CRISPR-Cas9: Now Knocking Out 12 Genes At Once

Mar 22 2021 - 17:03
Just a few short years ago, CRISPR-Cas9 technology took the world of molecular biology by storm because it allowed a cost-effective way to shut off or turn on traits in organisms without any side effects.

CRISPR is an acronym of Clustered Regularly Interspaced Short Palindromic Repeats, a bacterial defense system. The enzyme Cas9 acts like a pair of ‘molecular scissors’ that can cut two strands of DNA and insert of remove something. Then CRISPR repairs it.

Now it's gotten upgrade. Instead of one or two genes, a new study knocked out 12 at once.

Dog or Machine? Which is Better at Sniffing Out Bombs?

Mar 22 2021 - 16:03
Dogs have keen olfactory sensory neurons, receptor proteins great for differentiating smells humans never notice. One reason is basic biology; they breathe and smell separately. Electronic sniffers mimic many of the same processes dogs have - and require far less specialized training.

So which is better? The Reactions team at the American Chemical Society wanted to get the latest.

#MeToo May Have Caused Women To Lose Out On Mentors

Mar 22 2021 - 15:03
Even previously considerate and helpful male managers have become less likely to mentor female employees, according to a new study. They've even become less likely to even talk one-on-one with women.

This unintended consequence of the #MeToo movement could deny female employees critical development and thus career advancement. Women are not the problem, a large portion of female employees report a willingness to be mentored by an older male co-worker, but career advancement also has a social component, and in the last few years men are less likely to work one-on-one in an office with the door closed and less likely to engage in social behavior, like a post-work dinner with female employees.

Like And Trust Your Doctor? It May Lead To More PSA Tests Even If The Government Wants Otherwise

Mar 22 2021 - 14:03
Having a single primary care physician is statistically correlated to increased treatment adherence and decreased hospital admissions and mortality risk. A new paper finds it may also lead to costly unnecessary tests.

Male patients who have a single general physician were more likely to receive a prostate cancer screening test during a period when the test was not recommended by the US Preventive Services Task Force. Greedy doctors? No, the tests don't pay enough money to be meaningful, it is that doctors invariably prefer to side with patients over insurance companies or government protocols.

End Of The Uncanny Valley? The COVID-19 Pandemic Made Us Love Machines More

Mar 22 2021 - 13:03
Whatever Uncanny Valley when it comes to machines still existed in 2019 got a lot smaller in 2020. We're even being nicer to them since 2020.

People mostly dispense with social norms of human interaction and treat machines differently. The behavior holds true even as machines became more "human" seeming, such as Amazon's Alexa or Morgan Freeman in your vehicle navigation system.

Human default behavior is often driven by heuristic thinking -- the snap judgments people use to navigate complex daily interactions. The Uncanny Valley says that as artificial things begin to seem more human, but not close enough to pass for human, we are put off. 

That all changed due to COVID-19. We got nicer toward our machine and other people.

Neural Thrombosis, The Covid Vaccine, And Politicians Who Kill

Mar 17 2021 - 13:03
Last Monday at 10.30AM I eagerly queued up at the International Red Cross site of Padova, the town where I live and work, to receive a first vaccination shot against Covid-19. I duly received my dose and went back home with some relief. Little did I know that my relief would turn to anger very soon. 
My anger arose when I soon heard the news that the treatment with the vaccine I had been given, Astra-Zeneca, was being temporarily stopped, following the detection of a possible adverse reaction. But you should read on before you conclude that I am an idiot (as you indeed should, if the above was all there is to it).

How MRNA Vaccines Work – And Why You Need A Second Dose

Mar 16 2021 - 18:03

Tens of millions of people across the U.S. have received a coronavirus vaccine. So far, the majority of doses have been either the Moderna or Pfizer vaccine, both of which use mRNA to generate an immune response. These gene-based vaccines have been in the works for decades, but this is the first time they have been used widely in people.

Vaping Helps Smokers Quit - Including People With Schizophrenia

Mar 16 2021 - 13:03
Schizophrenia can cause hallucinations, delusions, trouble with thinking and other behaviors that impact daily functioning. Though it affects less than 1% of the public, 60% of schizophrenic smoke cigarettes, a known carcinogen and risk factor for numerous diseases; a 500 percent increase over the general population, where smoking has plummeted thanks to greater awareness of its harms plus smoking cessation tools like nicotine gums, patches, and vaping.

Beta Blockers Don't Cause Depression

Mar 16 2021 - 12:03
Beta-blockers are a class of medications that reduce the heart rate, the heart's workload and the heart's output of blood, which, together, lower blood pressure.

Blood pressure is only a risk factor for heart disease, it is not a disease in itself, yet when people hear about a medical issue with a vital organ it can have profound psychological impacts. Some people report feeling depressed or having fitful sleep after taking beta blockers. Plus anxiety, drowsiness, hallucinations and nightmares. When one medicine has so many diverse correlations without any biological plausibility, it is probably not the medicine, it is more likely the implications of the medicine.

46% Of Parents Say Responses To The COVID-19 Pandemic Damaged Teen Mental Health

Mar 15 2021 - 11:03
For as much talk as there is about bullying and drama in schools, for most teens the experience of interacting with peers is not only positive, it is essential training for dealing with others later in life.

And if a new national poll is an indication, government lockdowns and societal pressure during the COVID-19 pandemic may have lasting impacts on the mental health of young people.
