- What causes moles to appear on our skin?
- Is groundwater (i.e. the depth to the water table) affected by the gravitational pull of the moon like tides?
- Do we have greater precipitation due to the ice caps melting?
- Can ubiquitin be degraded via the proteasome?
- When leeches and bats suck blood does that blood goes directly on their bloodstream or on their digestive system?
- Why are left-handed people often excluded from psychological and neurological research studies?
- Is it possible (theoretically) to cause nuclear fusion through a purely kinetic method, or in layman's terms smash two objects together really hard to fuse them?
- Where there any deserts on Pangaea?
- Given the violent reaction with normal matter, what do scientists do with antimatter when they are through with it (plus another antimatter question in the comments)?
- What chemical processes give bread its crunchy crust?
- Why do sharks have eyes on the sides of their head?
- Can you deduce thermal properties of metals from their mechanical properties, or does their internal structure not allow for this?

- How were atoms/molecules observed before the quantum microscope and spectroscopy?
| Posted: 23 Mar 2018 04:00 AM PDT I am a paleontologist and professor at the University of Wyoming who studies fossil plants and ancient climate change. I have dug up fossils on six continents, with most of my work in Wyoming and Ethiopia. I co-produced and starred in The Bearded Lady Project: Challenging the Face of Science, a documentary film and traveling portrait exhibition that celebrates the work of female paleontologists and highlights the challenges and obstacles they face. You can read more about my work, research, and the fight for gender equality in the science community in Quartz's How We'll Win series. I'll be on at 2pm eastern (18 UT), ask me anything!

| Do we have greater precipitation due to the ice caps melting? Posted: 23 Mar 2018 04:38 AM PDT According to the front page, hydrological events are on the rise. Is this due to a lesser amount of the planet's water being locked up as ice at the Poles? [link] [comments]  |
| Can ubiquitin be degraded via the proteasome? Posted: 23 Mar 2018 04:04 AM PDT I'm learning about the ubiquitin-mediated proteasomal degradation pathway, and I was wondering if ubiquitin can be degraded by this pathway? Can it be degraded at all (by the lysosomal pathway or others)? [link] [comments]  |
| Posted: 22 Mar 2018 08:16 PM PDT And if the digestive system is the answer(most likely), how hard is to digest blood? [link] [comments]  |
| Why are left-handed people often excluded from psychological and neurological research studies? Posted: 22 Mar 2018 01:44 PM PDT Also, has there been any research on the impact this has had on left-handed people (i.e. is this cohort at a disadvantage, particularly when it comes to treatment efficacy, because they are so often excluded from research populations?)

| Where there any deserts on Pangaea? Posted: 22 Mar 2018 05:34 PM PDT These desertified lands does not seem normal for our planet, are they? Edit: "were", not "where" of course [link] [comments]  |
| Posted: 22 Mar 2018 04:21 PM PDT I have a couple of antimatter questions. A few years ago, scientists created some antihydrogen atoms and kept them suspended for around 20 mins (IIRC).

| Why do sharks have eyes on the sides of their head? Posted: 22 Mar 2018 04:56 PM PDT I grew up being told that herbavores have eyes on the sides of their heads to see predators, and predators have eyes on the front of their heads for depth perception, to catch prey. I just realized that sharks have eyes on the sides of their heads in spite of being predatory. Anyone up to explain? [link] [comments]  |
| Posted: 22 Mar 2018 02:06 PM PDT Aluminium, for example, has a low fracture point and elastic limit whereas steel's is very high. Does this mean you can know their relative thermal properties, or are the thermal properties of metals totally independent of this? [link] [comments]  |
| What determines which way graphite layers will face during crystallization? Posted: 22 Mar 2018 12:10 PM PDT |
| How were atoms/molecules observed before the quantum microscope and spectroscopy? Posted: 22 Mar 2018 04:57 PM PDT The period table began being built long before such technology but different elements were recognized. How? How do we know that in chemical reactions the molecules break up and recombine into those specific products? How were the elements/atoms in products observed? Thanks! [link] [comments]  |
