Askscience special thread - Panelists, what are you working on?

Posted: 04 Jan 2019 10:25 AM PST

Some the older members of r/askscience might remember this thread from a few years ago where we asked panelists of r/askscience to describe their research.

The idea to get our flaired users to post a brief description of one of their current projects. Hopefully this serves to foster some more detailed discussion about your specialties!

How come when you’re burned you’re not supposed to immediately put it in cold water? How does that hurt you more than help you?

Are people who were conceived using fertility treatment more likely to be infertile?

How does the spectrum of electromagnetic radiation emitted by an object change as the object's temperature changes?

Posted: 05 Jan 2019 07:06 AM PST

I know very little about science, but I spent part of the summer trying to learn about electromagnetic radiation. Then I took a long break. Now I'm trying to organize my notes, which are in disarray, and I want to make sure that I get everything essentially accurate.

I know that thermal energy contained within an object will be released in the form of electromagnetic radiation. And I know that as the temperature of an object increases, the spectrum of wavelengths emitted by that object will also change. But I'm not completely sure what the relationship is between temperature and emitted wavelengths.

I assume that hotter objects will release more high-energy wavelengths than colder objects - so for example, if Object X and Object Y are made out the same material, and Object X releases ultraviolet radiation, while Object Y doesn't release anything with a higher energy level than infrared, then I would assume that Object X is hotter than Object Y. Would that be an accurate assumption on my part?

Looking at stars on a clear night, why do they seem to be gently flickering?

Does your eyesight actually get worse if you read in the dark for extended periods of time or often do so? Why or why not?

Posted: 04 Jan 2019 03:13 PM PST

Do droughts have a specific cause that prevents rainfall for an extended period of time or are they a statistical anomaly of rainfall not occurring for an extended period of time?

When neutron stars collide do they immediately form a black hole or would the collision produce ejecta?

When touching very hot water, why does it sometimes take a split second to finally realize how hot the water actually is?

Why don't Orcas get large, creepy external parasites?

Posted: 04 Jan 2019 11:42 AM PST

I imagine they have some, but why not barnacles/whale lice (don't Google this within an hour of eating.)

How do Saturn rings affect sunlight on its surface?

Posted: 04 Jan 2019 04:53 PM PST

Does Saturn have a perpetual night zone where its rings cast shadow or is there a short darkness period every day on each spot of its surface (if we could say that it has one)?

Plant scientists, do you know of any plants whose trichomes (hairs on plants) move intentionally/functionally? What is the function or purpose of their movement?

How does Bluetooth work?

Why is there a minimum speed to leave Earth. Why couldn't you theoretically just walk up a large staircase if you had the equipment?

Posted: 04 Jan 2019 06:15 PM PST

Obligatory apologies for being on mobile.

Like if a staircase into space existed, why would that be impossible to walk up if you had a space suit? Is it the pull of gravity that gets more intense the farther you go? I hope I asked this the right way.

From the view of a chemist, why is lead so bad for humans?

Posted: 04 Jan 2019 04:02 PM PST

I am a new high school Chem teacher and am interested in exploring the Flint Michigan issues with my class from the standpoint of a Chemist. Is there a chemical reaction that we could discuss that would explain why Pb so bad?

How is allele dominant to another at a fundamental, chemical level?

Posted: 04 Jan 2019 08:24 AM PST

I'm a senior in college graduating with a degree in chemistry and have always been curious about gene expression at a chemical level. Like say height or eye color, what chemical force in DNA/RNA/organelles/whatever is causing a gene to be expressed more than another or make the allele/gene "dominant"?

How do serotonergic hallucinogens(LSD, Psilocin, DMT) increase brain interconnectivity?

Posted: 04 Jan 2019 09:29 AM PST

Obviously it's not literally rearranging neurons. That would probably be really destructive to the brain.

Do we lose intelligence, or get slower to learn new material / skills, as we age?

Posted: 04 Jan 2019 05:42 AM PST

...I'm 27 and am half-convinced I can notice this already, compared to when I was in my early twenties. I'd like to know if this is true, and what sort of rate this decline will continue to happen at?

Can pheromones repel animals from each other as well as they attract animals to each other?

Posted: 04 Jan 2019 02:33 PM PST

More specifically, I was thinking about how humans are drawn to each other to mate/love by pheromones - but on the other hand, can pheromones cause humans to kill/hate each other? Just curious. Thanks!
