Why hasn’t bacteriophage therapy become commonplace yet?

I feel like it's a discovery on par with something as revolutionary as solar power, but I rarely hear about it ever on the news. With its ability to potentially end the antibiotic resistance crisis, why hasn't this potentially game changing treatment taken off?

Do contact with the virus work as booster shots for vaccinated/recovered people?

Does the human body secrete more, less or equal amounts of sweat in dry versus humid environments?

Posted: 07 Nov 2021 04:03 AM PST

hot, humid environments hinder evaporation, causing a person to be visibly more sweaty than they would if they were in a dry climate.

However, my question is this this. If you were to place the same person in both environments with equal temperature, one with zero humidity and one with 100% humidity would the total volume of secreted sweat be more, less or equal in one environment over the other?

What if we conducted the same test again, but this time rather than equal temperatures, we used the "feels like" temperature index. In the dry environment it would measure 107 degrees, and the humid environment 95 degrees with a relative humidity of 50%, resulting in a feels like temperature of 107 degrees. Which environment would a person produce more sweat in if there is a difference.

This question originated from a discussion with friends about that new movie "dune". We are debating if a hot humid environment is more or less dangerous over a hot dry environment 🤔.

How small and detailed could we make a Fresnel lens?

Posted: 06 Nov 2021 08:38 PM PDT

Seeing them in the wild, you either look at it from a distance or they're quite grainy, I know they're cheap.

So, probably the image might look slightly like the way insect-vision is portrayed in movies, segmented like, but if we can make the tiny tiny little mirrors and sensors in DLP projectors and smartphone camera sensors, (I don't know if the features are smaller on phone cams or pro 16k cams or what) is there any way, expensive and convoluted it may be, to manufacture a super small scale fresnel lens that would provide a clear picture.

I understand this would likely never be profitable in a smartphone or anything but I just love the idea of a telescope that's much wider than it is long, or a pair of binoculars that's scarcely thicker than some thick glasses.

In case you can't tell I don't know how optics work.. I flaired it for Engineers because I suppose that's closest? Rather than physics?

I also just imagined a microtelescope could be made using a DLP mirror module as the collecting mirror with a little sensor in front of it, the uses however, escape me, aside from proof of concept or just messing about.

How does radioactive iodine work?

For treatment of hyperthyroidism, how does the orally ingested radioactive iodine only have an effect on the thyroid? How does it not cross to other tissue/the rest of the body?

A fetus can move around freely for most of its existence. As it grows larger, what compels it to settle with the head faced downwards?

What colour other than black absorbs the most light?

Posted: 06 Nov 2021 03:59 AM PDT

I would like a ranking of the top 5 colours that absorbs the most light after black.

Thanks

How do they conduct an experiment on a pill for a virus to determine the probability of surviving viral infection attributed to the pill?

Posted: 06 Nov 2021 09:51 AM PDT

Keep in mind:

I am wondering how they isolate other variables attributable to death/survival.

But also the physical process of creating this experiment, how do they find enough people who they know are going to die from covid without any kind of treatment?

If we divide numbers in A004090 with A060384 (sequences in OEIS related to Fibonacci numbers), will we get a constant value?

Posted: 06 Nov 2021 06:23 AM PDT

This is related to the Fibonacci sequence. In OEIS, there are many sequences related to the Fibonacci sequence, like the sum of digits of Fibonacci numbers A004090 and the numbers of decimal digits in n-th Fibonacci number A060384

I made graphs that showed the results of dividing A004090 with A060384, and when I drew the formula, it seemed like the graph tended to get close to certain value.

The graphs

For n = 500, the graph got close to 4.182, and for n = 10000, close to 4.48.

If the sequence of the Fibonacci number continues, what number will become a constant value of dividing A004090 and 060384?

Is it possible that new life has spawned on earth but we just didn't notice?

Posted: 05 Nov 2021 01:05 PM PDT

From my understanding life had to have just spontaneously happened at a single cell level and that life also happened to replicate/reproduce thus causing evolution. Is it possible other life has spontaneously been created but it didn't reproduce so it just died off before we noticed it?

How are granules made from powders to make those instant drink packets?

Posted: 05 Nov 2021 01:03 PM PDT

Crystal Light, Kool Aid, hot cocoa, whatever. Consumer product drink powders are granulized, don't clump in mild humidity, and dissolve quickly/easily as compared to fine powders.

How do I take my DIY drink powder mixes and "granulize" them?
