| Posted: 19 Jan 2016 05:00 AM PST Communicating science in the public conversation In an era where many policy decisions facing lawmakers and voters involve scientific issues, it's important that scientists engage with the public to communicate scientific knowledge. The Conversation is a non-profit, grant-funded news site dedicated to getting academics -- including scientists -- to share what they know with the general public. In addition to appearing on our site, all content is licensed freely under Creative Commons to other websites. The Conversation has editions (and editors) in the US, Australia, UK, Africa, and France. On the panel today are: Jonathan Garlick, /u/Jgarli01, Professor of Oral Pathology, Tufts University https://theconversation.com/profiles/jonathan-garlick-144707. Dr. Garlick's research expertise is in stem cell biology, wound repair, and human tissue engineering through which he has developed new therapeutic approaches for cancer, wound healing and complications of diabetes at Tufts University. He is leading a national initiative in Civic Science with Tisch College at Tufts to inform public learning about science-based issues that impact our lives as a bridge towards creating an inclusive, national science dialogue. Jonathan Wai, /u/waijon, Research Scientist, Duke University, https://theconversation.com/profiles/jonathan-wai-186368 Wai researches and writes about the development of talent, broadly conceived, and its impact on society. David I. Miller, /u/davidimiller/ Doctoral Student in Psychology, Northwestern University, https://theconversation.com/profiles/david-miller-163531. Miller is an advanced psychology doctoral graduate student at Northwestern University studying how and why students move into and out of science and engineering fields. Maggie Villiger, /u/MaggieVvv, Science + Technology Editor, The Conversation US https://theconversation.com/us/team#maggie-villiger. Maggie has a background in broadcast journalism, having worked in both public radio and television, and has degrees in neuroscience and science communication Our panelists have written on this issue, including Here's why academics should write for the public and To seek common ground on life's big questions, we need science literacy. We'll be on from 12-2 PM ET. We'd like to discuss the challenges and necessity of talking to the public and asking and answering science questions. AUA! [link] [18 comments]  |
| How does glue work at an molecular level? Posted: 19 Jan 2016 04:39 AM PST Does it bond with the contact material or is there a more simple 'sticky' explanation? If the glue does not bond with the contact (as I assume is does not because of the relative ease of separation) then how does it stick in the first place while losing it's initial stickiness when hardening?

| How does 14nm lithography work? Posted: 19 Jan 2016 03:56 AM PST I am wondering what technology the semiconductor industry utilizes to achieve 14nm feature sizes. I searched the web for a while but could only find stuff about Moore's law and why 14nm is great, but nothing tangible about the actual manufacturing process. Would be great if someone could help out! [link] [10 comments]  |
| Biology: Do snakes/fish/limbless animals have handedness? Posted: 18 Jan 2016 07:42 PM PST For example, if they are trying to move - will they favour using muscles on one side first? Asymmetrical chewing perhaps? [link] [14 comments]  |
| How does a GPS satellite handle all the requests from smart phones and other devices? Posted: 19 Jan 2016 04:50 AM PST |
| What's the difference between Fisher information and Shannon information? Posted: 18 Jan 2016 08:00 PM PST |
| How do volcanologists determine that a volcano became dormant millions of years ago? Posted: 18 Jan 2016 07:25 PM PST How are they able to get estimates like that? How is it possible to tell that a volcano last erupted millions of years ago? [link] [6 comments]  |
| Could you use high powered lasers to burn/char paper instead of using ink? Posted: 18 Jan 2016 07:26 PM PST If you have the right amount of power and the right thickness of paper, could you theoretically burn a small amount into a piece of paper and simulate black ink? [link] [22 comments]  |
| Why do electron orbitals form the shapes they do? Posted: 19 Jan 2016 12:31 AM PST I am a high school student who has recently begun learning about chemistry and I have found it relatively simple. However, the one part about chemistry that has been difficult to grasp has been electron orbitals and why they form in the ways they do. I am under the impression that everything in science has an underlying reason for it, so why is that these orbitals form in seemingly 'random' ways that do not make any intuitive sense? And why would the 4s orbital have a lower energy level than the 3d orbitals? Also is there theoretical an infinite number of orbitals if you just add more electrons? If there is a pattern to the orbitals how would we go about predicting the form they would take? If anyone could give me an answer as long as it is does not require college level math or extensive prerequisite knowledge of the subject it would be greatly appreciated [link] [2 comments]  |
| Posted: 19 Jan 2016 06:58 AM PST If a particle collider can speed up material to nearly the speed of light, my thought is that we could measure decaying material and put it into the Large Hadron Collider, and check if more material has decayed than if it was at a standstill. Am I on a plausible train of thought here? Is "nearly the speed of light" fast enough? [link] [7 comments]  |
| Why does the melting point of hydrous rock decrease with increasing pressure? Posted: 18 Jan 2016 08:09 PM PST While the melting point of anhydrous rock increases with increasing pressure? [link] [1 comment]  |

| Why doesn't blowing high pressure air at an object heat it up? Posted: 18 Jan 2016 07:35 PM PST If heat is atoms moving very fast such that when a high speed atom collides with a low speed atom the transfer in kinetic energy is also the transfer of heat (i'm thinking like billiard balls) why is it that blasting air at an object doesn't heat it up? Shouldn't adding kinetic energy into moving the air at a high speed cause that kinetic energy to transfer to the atoms in the stationary object and increase their speed and thus transfer heat?

| How would a plunger or other suction cup type things behave in a vacuum? Posted: 18 Jan 2016 06:30 PM PST Would it blow up? Create a black hole? Disappear? Enlighten me. [link] [8 comments]  |
| Posted: 18 Jan 2016 10:14 AM PST Given dolphin's extensive use of sonar/echolocation to understand their surroundings, and the complex nature of their clicks/whistles, has there been any research into whether dolphins perceive their auditory language spatially? Have there been any efforts to map dolphin communication to spatial/SONAR models, e.g. instead of communicating an idea in a piecemeal, time-series fashion like humans do with our low-bandwidth spoken language, could dolphins basically be transmitting an entire picture of their idea, where it would take us dozens of words to do the same? Edit: Gee, I wish I could tag this as biology, neuroscience, and computing too =( [link] [3 comments]  |

| What controls the rate of burning in a candle? Posted: 18 Jan 2016 04:10 PM PST I looked a little into how candles work, and it was something along the lines of the wax that is evaporated is what is actually burned. I put in some paper towel into an old candle without a wick, to act as the wick. It worked great for a long time, but I found it latter as a big ball of fire inside the candle jar, not even attached to the wick. just all the hole volume of the jar was burning. There was a lot of paper towel in their, so did that somehow allow there to be far more vapor to burn? Did the abundance of wick just evaporate too much paraffin? [link] [5 comments]  |
| Did the Earth have rings for a period of time after the impact that ultimately created the moon? Posted: 18 Jan 2016 09:14 AM PST |
| Is there an equivalent to the "Planck Length" for time units? Posted: 18 Jan 2016 02:11 PM PST And if there is, shouldnt it be possible to calculate a momentous velocity of an object based on the fact that there's a "minimum" timescale? [link] [8 comments]  |
