AskScience AMA Series: "I am Rhett Allain, physicist and technical consultant on Mythbusters and MacGyver. Ask me about the physics of pretty much anything!
When does a mushroom die? When it's picked? When it's packaged? Refrigerated? Sliced? Digested?
Does a Mayfly, which only lives a day, evolve fast than a human?
As a snake grows in length, does it grow additional ribs and vertebrae, or do they have a set number?
What is special about sunlight versus artificial light that plants need it?
Why isn't Boron created through normal stellar nucleosynthesis (i.e. nuclear fusion in stars)?
Do other animals have 'accents' like humans do?
Do Lagrange points exist for planets in elliptical orbits?
What is the reason for Ethiopia demographic boom in recent years?
Has there ever been a trench deeper than the Marianas Trench in Earth's geologic history?
Is body chemistry affected by sound, in the same way that melatonin production is affected by light?
How do earthquakes happen that are far from tectonic plates fault lines?
Have we ever seen a stellar ignition?
Why are green aurora borealis more common than the red/ purple ones?
How does a flu vaccine lessen symptoms when you catch a flu variant that isn’t one of the variants in that seasons vaccination?
How do satellites in space protect their electronics from all the different types of Electromagnetic waves they are exposed to?
what determines the life span of organisms?
Are there any successful attempts to create a substance that is made up entirely with antimatter particles?
How much of an effect do the Sun and the Moon have on the Earth's axial precession, if any?
Why can’t we increase the wattage of chargers to make devices charge faster?
How do they catch interplanetary dust particles?

Is there any organism that has more than one brain?
Do NSAIDs, such as ibuprofen, reduce specific areas of inflammation or do they reduce inflammation overall?
What are all the swirly patterns on Jupiter?
How do bonding and anti bonding orbitals form?
Does sunlight lose any energy or specific rays (UV-A, UV-B, etc.) when it's reflected by a mirror?
Why do some plants need full strong direct sunlight but others need partial shade and indirect sunlight? What is the physiological/chemical reason behind this?
How much radiation does a luggage scanner deliver vs say medical x-ray?

[chemistry][nuclear physics] if the island of stability does exist, do we have any way of estimating what the behavior/properties of those elements will be like?
How do we know the temperature of the centre of the sun?
When sound waves interfere in air, they create beat frequencies. Does this also happen when electromagnetic waves interfere in space?
Will more electric cars on the road have any positive effect on the environment if electricity to power these cars is still generated by fossil fuels?
