Sapana V. trained as a cancer biologist specializing in inherited risk genetics for acute leukemia. She joined the State Department's Biosecurity Engagement Program (BEP) as a AAAS Science and Technology Policy Fellow in 2015. Her primary BEP responsibilities include setting priorities and implementing programs in several countries in the Middle East and North Africa region, participating in interagency meetings on biological policy issues, and managing BEP's annual budget. In January 2016, she was promoted to Acting Deputy Team Chief for BEP. Prior to joining the State Department, she was a Mirzayan Science and Technology Policy fellow and research associate at the National Academies of Science, Engineering, and Medicine where she helped develop the "Ovarian Cancers: Evolving Paradigms in Research and Care" report. She holds a Ph.D. in Cancer Biology from the University of Chicago and a B.S. in Biology and English from the University of North Carolina at Chapel Hill.

She'll be on starting at 2 PM ET (19 UT)!

Is there any physical differences in the brain with an individual with a high IQ number and an individual with an average one?

Posted: 27 Jan 2017 07:34 PM PST

If there isn't any physical differences, how do you differ an individual with a high IQ and an individual with a low one?

And are these differences tied with genetics?

Which is larger, the largest known star in the Universe or the largest known black hole in the Universe?

If tomorrow I came up with a way to algebraically solve any nth order, nonlinear differential equation, what would we be able to know that we do not now?

Do anti-inflammatory drugs (NSAIDs) prolong infections?

Posted: 28 Jan 2017 07:51 AM PST

So my logic here is that since inflammation is the way the human body deals with pathogens, wouldn't that mean that disrupting this process (for comfort or otherwise) prolongs the infection?

For example fever exists for a reason, so why should we attempt to lower it (if it's in acceptable bounds)?

I just saw a post elsewhere about super-massive black holes. What is the SMALLEST mass a black hole could have? Would a single "black molecule" be theoretically possible? An atom? Could a single proton be a black hole?

Is poincarre recurrence/eternal return of the universe well accepted? Doesn't a continually expanding universe make it increasingly less likely with time?

Posted: 28 Jan 2017 07:21 AM PST

So, I watched this incredible video by Dr Tony Padilla and Brady Haran at Numberphile (https://www.youtube.com/watch?v=1GCf29FPM4k)

I can understand that if our universe was not continually expanding then it would eventually return to a state similar to what it is today, but in an accelerating expansion of the universe, won't all particles eventually be moving away from each other at apparently superluminal speeds? Doesn't this make poincarre recurrence impossible eventually?

Also, I know there are theories that quantum tunneling may generate a new big bang in the far future. Is this a well accepted theory?

Is there a temperature gradient on Mercury?

Posted: 27 Jan 2017 08:16 PM PST

The hot side of Mercury is 800 degrees F, and the cold side is -290F. Could there be a narrow band of hospitable temperatures where we could do a manned landing?

Why are volcanic erruptions causing volcanic winters even though they emit CO2?

Posted: 28 Jan 2017 02:53 AM PST

Hello, student here, dealing mainly with climatology and GIS.

Recently I've had a quarrel with a client at the shop I am working at. He denied climate change so I tried to talk to him about it. I couldn't answer the question you see in the title.

Now that I think about it I am guessing that volcanoes emit volcanic ash, sulphur dioxide and other gasses AND CO2. So the CO2 gets into the atmosphere and it does contribute to warming, but the ash cloud prevents the energy from reaching the earth. Is it correct or am I confusing something here?

Also, another question of his wnich confused me was about the CO2 effect on warming. He said that the if the CO2 blocks radiation, then it should also block incoming radiation from sun. So it would block some of incoming radiation, and some of the earth's radiation and it should even out. I know that's not the case, but my courses don't teach ANY physics, even those dealing with climatology and climate change, so my understanding of these issues is very poor considering I am a student related to the subject. But I want to learn :( I did try to get a grasp of some basic university level physics on my own (tho failed miserably at that), so I would love you to provide a reasonably detailed explaination. I'd like to know what happens, how and why. I would gladly be also directed to any articles that deal with this issue.

In advance, thanks for help :)

Are the protons and neutrons of a given element always packed in the same configuration?

Posted: 27 Jan 2017 05:57 PM PST

Take a Carbon-12 atom, for instance. It has 6 protons and 6 neutrons which are, presumably, held together in some configuration by the nuclear force. I imagine them being stacked together like the bouncy balls in the big cage in the toy section at the super center.

Is the stacked configuration always the same for every atom of C12, can it vary from one to the next, do we not have the technology to discern, or does it simply not make sense to think of nucleons as physically round objects nestled together like bouncy balls?

What is the relationship between blood sugar and appetite, if any?

Posted: 27 Jan 2017 04:48 PM PST

So far I've found this, but the sample size is tiny and very specific (eight males ages 19-40) for such a broad topic, and their definition of appetite seemed rather ill-defined ("visual analog scale"? couldn't find a supplemental doc or anything that clarified further).

How are lightsails propelled if photons are traditionally said to have zero mass?

Posted: 27 Jan 2017 07:21 AM PST

In a vacuum, how does light propel a lightsail if it has zero mass? Does F = ma in this case?
