Can moths or butterflies remember experiences from before their transformation?

Posted: 22 Jul 2021 09:48 AM PDT

I was wondering if caterpillars have any sort of memory or habit forming patterns. Say for example they locate a really good area rich in food and other mates. After transformation is it possible for then to remember that location? Or are they completely born new and fresh and rely on instinct alone?

What's the 'Mortality trend' in the covid-19 re-infection cases?

Posted: 23 Jul 2021 06:27 AM PDT

I'd like to know if there has been a research study yet (or an epistemological trend), as to, on the mortality rate of people who have had a covid Re-infection.?

Any data on the people who have been with asymptomatic or mild or moderate (non-hospitalized) covid-infection the first time, how did they fare, during the second time(or so on), if indeed they get re-infected with novel Corona virus?

Does any trend shows that people with re-infection were nearly immune to mortality, if they caught "non-hospitalization" kind of Corona the first time?

How do we test for the different variants of Covid? (Alpha, beta, delta, lambda, yada)

Posted: 22 Jul 2021 11:23 AM PDT

Do we look for different DNA sequences with the PCR tests, different symptoms? With all the media hammering on about the variants it would be nice to actually know how we identify these.

Why aren't Lagrange points the Earth-Moon system affected by the Earth-Sun system?

Posted: 22 Jul 2021 11:48 PM PDT

This question came to me from reading this in the Lagrange point wiki:

There are five such points, labeled L1 to L5, all in the orbital plane of the two large bodies, for each given combination of two orbital bodies. For instance, there are five Lagrangian points L1 to L5 for the Sun–Earth system, and in a similar way there are five different Lagrangian points for the Earth–Moon system.

Is everything (all the systems above the Earth-Moon) already considered when calculating the Earth-Moon Lagrange points, or is there a reason they can be calculated in isolated and persist even when placed in a larger system such as the Earth-Moon?

What do we really know about the interior of gas giants?

Posted: 22 Jul 2021 01:12 PM PDT

Like what are we actually certain of?

Are there really layers where diamonds are known to precipitate? How does the carbon get back uonto higher layers to rain down again instead of accumulating somewhere lower?

At what depth do metallic liquids occur?

What sort of cores do gas giants have?

Is there anything that we can say about the interior that has been ruled out by the Juno data or perhaps made more likely?

How do people constrain the elemental budgets of non-terrestrial planets? Or maybe they just don't?

How far could a meteorite penetrate into Saturn or Jupiter?

Would it hurt a caterpillar to metamorphose?

Posted: 22 Jul 2021 01:37 PM PDT

If the enzymes are liquefying their body structures, wouldn't that include melting their nerves? Would that hurt? We know caterpillars sense pain due to experiments where they have avoided stimuli that produce electric shock. Or does their brain 'melt' before they can even process the pain of melting nerves?

How do we determine the age of the universe?

Posted: 22 Jul 2021 05:34 PM PDT

My understanding is the oldest light we can see is 14+ B years old...

Since the universe is expanding, is it possible "older light" than the oldest light we see has already moved beyond a cosmic horizon, forever too far away?

I'm sure there is an answer to this but I am curious.

Thanks!

Why are AstraZeneca and Pfizer equally effective in the real world but were wildly different in trials?

Posted: 23 Jul 2021 06:59 AM PDT

In testing Pfizer was reported to be around 95% effective and AstraZeneca 70% effective. Yet, in Britain where millions of people have had them it appears that both are equally effective at around 90%.

Why is this? Did the trials for AstraZeneca include asymptomatic cases and Pfizer not?

EDIT for links:

Public Health England: Hospitalisation Pfizer 96% AZ 92% https://www.gov.uk/government/news/vaccines-highly-effective-against-hospitalisation-from-delta-variant

Another link saying they are similar https://www.medrxiv.org/content/10.1101/2021.04.22.21255913v1.full

It appears Pfizer is more effective than AstraZeneca against delta/Indian covid

How High Can Bugs Fly?

Posted: 22 Jul 2021 12:33 PM PDT

Can a Dragonfly fly 1km up in the air? Is there a maximum to how high they can go? If so, why? Does this change from mosquito to bee to dragonfly?

what is the underlying cause of the Peltier effect?

Posted: 22 Jul 2021 05:35 PM PDT

I looked online but I didn't find a lot of information about what causes the Peltier effect. Can someone explain it or point me towards some resources?

Do compost piles attract flying predators that eat mosquitos?

Posted: 22 Jul 2021 05:17 PM PDT

I've often wondered if my backyard compost pile helps to net reduce mosquito populations because it provides a stable food source for lots of flying insects (fruit flies in particular). Do fruit fly predators also eat mosquitos? Do you think the pile would have a significant effect on local mosquito populations?

What assays are used to measure protein solubility?

Posted: 22 Jul 2021 10:20 PM PDT

https://en.wikipedia.org/wiki/JUNQ_and_IPOD#Discovery mentions this below

  • Solubility (e.g. by using the FRAP assay[11])

But gives no further details...

Why are none of the COVID vaccines Live vaccines? Would a Live vaccine not offer better immunity given that the actual whole virus is present?

Posted: 23 Jul 2021 04:34 AM PDT

Follow up questions, would a recovered infection provide a stronger immunity (damage caused by illness notwithstanding), and would Live vaccine/ recovery provide better protection against variants?

I've tried looking this up but seem to only find fact-checking articles debunking claims about the vaccines containing the virus, or articles explaining how the current vaccines work. It also seems there isn't as much information about recovered immunity as opposed to the vaccines.

Appreciate any help

What is the difference between annealing and tempering?

Posted: 22 Jul 2021 03:31 PM PDT

It seems like both of these are used to refer to heat-treatment of metals, but (as I understand it) annealing tends to increase grain sizes while tempering reduces them.

Why do some phone companies say "%60 charge in 10 minutes" instead of saying "full charge in x minutes"? Does it get harder to charge when its closer to full capacity?
