officialjunk··on Our brains 'time-stamp' sounds to process the words we hear
by this logic, with humans having millions of neurons in other parts of the body, such as the gut, we may have consciousness spread out over the body, not just the brain.
officialjunk··on NASA’s Webb takes star-filled portrait of Pillars of Creation
yes, hubble's image is closer to what you could see with your eyes, since we also (mostly) sensitive to visible light. the zoom magnification is different, though, of course.
officialjunk··on TIL: You can access a user’s camera with just HTML
i do, but only the front facing camera though pointing at my face.
officialjunk··on Lenovo’s Glasses T1 let you bring a private big screen display with you
ah. thanks for pointing that out! i didn't realize it.

officialjunk··on Our brain is a prediction machine that is always active
there's also subconscious lying, such as hiding our blind spots where the optic nerve is attached to the retina and turning off our vision when we move our eyes, and toying with our perception of time passage to make it seem like there was no gap in vision.
officialjunk··on Where is there more livestock than people?
isn't the corn based diet unique to the United States, since corn is a subsidized crop?
officialjunk··on Einstein-Bohr debate settled once and for all
entanglement is not permanent; decoherence.
officialjunk··on New Covid nasal spray outperforms current antibody treatments in mice
The mucosal immune system in the respiratory tract is the first line of defense against covid. An interstitial injection does not train the mucosal immune system, while a nasal vaccine does. To prevent any infection, the mucosal immune system needs to be primed.
officialjunk··on Show HN: Covid – How long did you make it?
what about the long term impacts that we are still learning about? cardiovascular disease diagnoses are up 15-20x (1500-2000%) for those with prior covid infections, even asymptomatic and even children.
officialjunk··on Possible Outcomes of the Russo-Ukrainian War and China’s Choice
Yes, China may even think the most long term of current governments.

officialjunk··on 4th Dose Covid mRNA Vaccines’ Immunogenicity and Efficacy Against Omicron VOC
yes! some nasal/inhaled vaccines are in trials in other countries, but i am not aware of such progress in the US. it will really help PREVENT infections and not just reduce the severity of symptoms.
officialjunk··on CDC says Americans can now go unmasked in many parts of the country
then why isn't the whole world taking off masks?

also to quote the transcript "The pandemic is still here. We're not at the endemic phase yet. But I do think we're transitioning, and I think it's a good roadmap."

officialjunk··on Ask HN: Does anyone else miss TouchID?
awesome!
officialjunk··on Ask HN: Does anyone else miss TouchID?
i wish the touch bar was slightly shorter and the keyboard had a dedicated escape key instead. the function keys i use much less frequently.
officialjunk··on We purchased a machine from China and it came with malware preinstalled
you need to travel internationally more.
officialjunk··on The Universe Is Expanding Faster Than It Should Be
say an advanced civilization learns how to time travel and walk the multiverse. trying to find us would be hard. the time scale is very small, yes, we occupy a small area, true, but also the scale of life itself may not be discussed much.

there's dozens upon dozens of orders of magnitude of space that a being could occupy. scanning for life through the multiverse and time, it would also be easy to miss us. too small and you see cells and organelles, larger we see organs mixed with bacterial cultures, etc, and at just the right scale we are visible.

there are arguments that earth is a living entity, and there may be larger forms of life going many orders of magnitude larger than planet-sized.

with such a large range of time, location and scale to scan for life, it could be argued we basically don't even exist.

officialjunk··on Single-celled Organism Dies [video]
does anyone know what is happening to this organism? it looks like the cell wall ruptures?

from the description:

> This is a single-celled organism in the genus Blepharisma and it is dying. I don't find them in my samples often, they usually have pinkish color and they are photophobic it means when the light levels are increased they will try to swim to the darkened areas. If they are exposed to light or starved, they will lose their pinkish color and will look like this one in the video, also strong light can even kill the colored ones. I don't know why this one died but how it dissolves to nothingness just broke my heart. Big or small, life is fragile.

officialjunk··on Two Triple Vaccinated Israeli Doctors Infected with Omicron
i agree with you, but i am having a lot of difficulty convincing most people i know that the current vaccines are leaky. i find most people still consider the current vaccines to neutralize the virus and they often begin to question why i don't understand how vaccines work...
officialjunk··on Time Travel: Probability and Impossibility
In case you didn't know, Physicist Richard Feynman proposed the idea that positrons could be electrons moving backwards in time in his paper "The Theory of Positrons." He even takes it further to say that it could be that there is only 1 electron in the entire universe and it is traveling forwards and backwards in time to appear in the positions of all the electrons and positrons.
officialjunk··on China to build 150 nuclear reactors- more than rest of world over last 35 years
The US has contributed more than any other country to carbon emissions, at double China's emissions so far. https://ourworldindata.org/contributed-most-global-co2
officialjunk··on Female African elephants are evolving without tusks due to ivory poaching
but the tusks had a purpose to defend and now they are defenseless.
officialjunk··on New evidence shows this uranium cube is likely relic of Nazi A-bomb program
https://ourworldindata.org/grapher/military-expenditure-by-c... i would expect it to be correlated with military spending
officialjunk··on Cognitive deficits in people who have recovered from Covid-19
i can't seem to find it in my notes right now. i came across the study when looking into the increase of kawasaki syndrome post "asymptomatic" covid infections in children last year. i do have this paper in my notes that speaks of a 30 fold increase in kawasaki diagnoses: https://www.nature.com/articles/s41591-020-0959-4

since then, we now call this post-covid complication MIS-C and there's increasing coverage and study into it. i do recall coming across another study looking at a more broad range of age groups and noting a 20 fold increase of cardiovascular diagnoses.

overall, we still have a lot to learn about this virus.

officialjunk··on The world needs a proper investigation into how Covid-19 started
we need to solve the pandemic problem first
officialjunk··on Cognitive deficits in people who have recovered from Covid-19
too early to say. there's a spike in cardiovascular disease, on the order of 20x since the pandemic. the commonality is prior covid infection.
officialjunk··on AstraZeneca Scientist Says Delta Variant Makes Herd Immunity Impossible
is the origin really known?
officialjunk··on Tesla big battery fire under control after burning more than three days
The runaway heat issues, with the chemistries applied now, are mainly due to which other elements are involved. Cobalt is a huge factor.

It is true all batteries heat when charging, but this is not what I am talking about here. Simpliphi batteries do not require any cooling system because the chemistry is more thermally stable and does not have a risk of thermal runaway, even charging at high power. Tesla batteries have a cooling system not for the heat generated by charging alone, but because of the runaway thermal reactions involving cobalt.

officialjunk··on Tesla big battery fire under control after burning more than three days
This is not true. There are different chemistries. Tesla hardware, as many others, requires an active cooling system because of the KNOWN thermal issues with involving cobalt. There are lithium ion batteries without cobalt, such as Simpliphi, that do not have any runaway heat issues and therefore do not require a any cooling system, but this lithium chemistry increases the cost.
