What adaptations do dolphins and other marine mammals have to see clearly under water and how does that affect their vision above water?

Does a simple fire emit ultraviolet light? lf no, then how does our sun do so? Ks it a matter of thermonuclear fusion, or something else?

Is the volcanic and geological activity of the past few years unusual?

Posted: 05 May 2018 05:42 PM PDT

Activity in Yellowstone, Greenland, and in multiple places around the world.

Hawaii now has a new volcanic formation with recent activity...

It feels abnormal. How much of this feeling is based on science, and how much is media hysteria?

Also, what is possibly causing this (percieved) increase in activity?

How did Ice Ages and extremely hot periods end in history?

Posted: 06 May 2018 05:32 AM PDT

So I hear a lot about positive feedback loops: ice disappears, less heat is reflected back into space, more CO2, more heat is trapped, ice melts, etc.

And the other way around: earth gets colder, ice forms, more heat is reflected, more co2 trapped in ice, less heat is trapped, ice forms etc.

So how did these loops break in earths history?

Since the ocean is so vast and fish are pretty mobile, how do we determine where a certain kind of fish is "from". Do they have multiple geographic homes?

Posted: 05 May 2018 08:55 AM PDT

I am sure temperature, latitude, and depth are some of the pieces of relevant info, but can we really say where a fish's "home" is?

How many calories do insects usually consume in a day?

Posted: 05 May 2018 06:20 PM PDT

It has to be such a small amount but I'd imagine it's very easy to overeat if everything around you is massive right?

Why are there a lot more right-handed people than left-handed people?

About an 80/20 split between right and left?

Why must two quantum mechanical observables have their commutator equal zero if they are to be simultaneously observable?

I've been researching Ketogenic Diet & Intermittent Fasting. If that gives any context as to which mindset the speakers were coming from

What negative effects (if any) are we causing by increasingly introducing antibacterial products to our water waste?

Posted: 05 May 2018 11:25 PM PDT

I understand our water waste leads to sewage treatment plants before being re-released into the environment, but does this process insured that these products never enter the environment?

What is a Quantum Mechanical understanding of absolute zero?

Posted: 06 May 2018 04:24 AM PDT

Classically, the temperature, of some peice of matter, is the average kinetic energy of all the particles that make it up. So absolute zero is just when the every particle has zero kinetic energy. But from Heisenbergs uncertainty principal we know that uncertainty in momentum cannot be zero, thus restricring momentum of a particle to some finite value, thus restricring kinetic energy to some finite value... and you can see where I'm going.

The victims of the Mt. St. Helens volcanic explosions: what happened to the bodies that were never found?

Posted: 05 May 2018 04:16 PM PDT

I understand many of the victims were exposed to high wind, high heat, and flying debris; any of which could have been fatal. Volcanologist David Johnston was quite a ways from the volcano, but was never found. Harry R. Truman lived near Spirit Lake and was covered in something like 150 feet of mud. Is it possible that many of the victims became fossilized? Has there been any attempts to uncover victims or structures?

What precautions will be taken by the Mauna Kea Observatories in the event of a volcanic eruption?

Posted: 05 May 2018 02:31 PM PDT

A nearby volcano, Kīlauea, is starting to show activity, will that cause problems with ash, dust, earthquakes, etc at the Mauna Kea Observatories?

What casuses air to diverge jn the upper troposphere to cause low pressure?

Posted: 05 May 2018 11:19 PM PDT

Can't find any useful info on this so far. I just want to know the scientific reason behind diverging air high up which creates lower pressure near the surfice as warm air rises to replace the air leaving the column

If plants ‘Breathe in’ CO2 for photosynthesis then use it in respiration for energy, how do they get rid of the CO2 that they gained from the air?

Posted: 05 May 2018 06:20 PM PDT

Photosynthesis is endothermic 6(CO2)+6(H20) => C6H12O6 + 6(O2)

Respiration is exothermic C6H12O6 + 6(O2) => 6(CO2)+6(H20)

I would guess the extra carbon is used to build cells as wood is combustible hence has carbon in it, but I'm not sure.
