- Do geese belong to individual flocks, or can they just join up with whatever flock is headed in the right direction?
- How can a phone tell the exact percentage of the battery?
- When someone receives a heart transplant as a child, does the heart grow with the child?
- What happens to air that escapes the ISS?
- How will the ISS 'land'?
- How do we know that the concept of dark matter isn't just the observed gravitational effect of undetected black holes on their surrounding stars and galaxies?
- How is a bionic arm controlled?
- What causes the symptoms of motion sickness and why do medications such as scopolamine in a transdermal patch alleviate these effects?
- What happens to proteins over time? Do they degrade, are they broken down in by the cell, do they just hang around? How long will a protein stay viable?
- In the last 50 years, ten volcanic-made islands were formed. Is this a consistent and predictable rate? If so, can/will the earth over millions of years eventually become solid volcanic rock? Why or why not?
- Can a particle accelerator beam be referred to as a Laser?
- What's stopping us from creating smaller than ~5nm transistors and also makes it difficcult to even reach there?
- Can you make a nuclear bomb with any element?
- Did all written language originate from a single early language?
- Neurologically speaking, what makes a child's brain better at learning new skills and languages than that of an adult?
- How does an electron multiplier release upwards of a million electrons from just one? Where do those electrons come from?
- Does animals of same species understand each other irrespective of the country they came from? Not talking about human beings..!
- How much does the change in climate affect the spread of cold and flu viruses In places that experience the change in seasons more rapidly?
- If Andromeda is going to hit us but we are actually seeing that galaxy in the past, does that mean that Andromeda might have already hit us?
- Water vapor is Earth's primary greenhouse gas both in quantity and effect. What prevents the cycle of the atmosphere heating, thus able to hold more water, thus heating the atmosphere even more, and so on?
| Posted: 30 Aug 2018 04:00 AM PDT Hi, we are Dmitri Pavlichin (postdoc fellow) and Tsachy Weissman (professor of electrical engineering) from Stanford University. The two of us study data compression algorithms, and we think it's time to come up with a new compression scheme-one that's vastly more efficient, faster, and better tailored to work with the unique characteristics of genomic data. Typically, a DNA sequencing machine that's processing the entire genome of a human will generate tens to hundreds of gigabytes of data. When stored, the cumulative data of millions of genomes will occupy dozens of exabytes. Researchers are now developing special-purpose tools to compress all of this genomic data. One approach is what's called reference-based compression, which starts with one human genome sequence and describes all other sequences in terms of that original one. While a lot of genomic compression options are emerging, none has yet become a standard. You can read more in this article we wrote for IEEE Spectrum: https://spectrum.ieee.org/computing/software/the-desperate-quest-for-genomic-compression-algorithms In a strange twist of fate, Tsachy also created the fictional Weismann score for the HBO show "Silicon Valley." Dmitri took over Tsachy's consulting duties for season 4 and contributed whiteboards, sketches, and technical documents to the show. For more on that experience, see this 2014 article: https://spectrum.ieee.org/view-from-the-valley/computing/software/a-madefortv-compression-algorithm We'll be here at 2 PM PT (5 PM ET, 22 UT)!

| Posted: 29 Aug 2018 07:37 AM PDT I just watched a large V of geese go overhead, then split apart into two groups and head to different directions. There were also a couple of stragglers rushing to catch up, one of whom seemed to have missed the boat completely and just kept going straight, blazing his own path. Will that goose be looking around at some point for his family / friends? Will they just be looking around for any flock of geese to join up with? I assume that there are only a few main flyways, and they can catch up with their own flock "on the road", as it were, but does that matter to them? [link] [comments]  |

| When someone receives a heart transplant as a child, does the heart grow with the child? Posted: 29 Aug 2018 06:44 PM PDT I don't know much about this stuff but I'm really curious. If someone receives a heart transplant or another transplant as a child, does the received organ grow with the child? Or does it stay the same size as it's a foreign body and they need to receive and adult one later on? Or is it the same size anyway? [link] [comments]  |
| What happens to air that escapes the ISS? Posted: 30 Aug 2018 06:24 AM PDT Generally, what happens to air that escapes the ISS? Does it eventually get reabsorbed into Earth's atmosphere? Or is it stuck up in orbit or escape our planet? [link] [comments]  |
| Posted: 30 Aug 2018 02:25 AM PDT Keeping the ISS at 400km height and delivering food for the astronauts is really expensive and as much as I know ISS will run out of funding in the next 10ish years. So what will happen with the station? Making it leave orbit will be impossible so how will it come back to earth? [link] [comments]  |

| How is a bionic arm controlled? Posted: 30 Aug 2018 07:26 AM PDT I have seen videos where people just but the bionic arm on there body and it suddenly works. [link] [comments]  |

| Can a particle accelerator beam be referred to as a Laser? Posted: 29 Aug 2018 11:20 PM PDT I read an article about Anatoli Burgorksi, the Russian scientist who survived after being struck by a particle accelerator beam to the head. The article uses the term" High-Powered Laser" in the headline. Is this just a sensationalised headline or is it acceptable to use the terms, Laser and Particle Beam interchangeably?

| Can you make a nuclear bomb with any element? Posted: 29 Aug 2018 07:58 PM PDT Could you use an element like gold, or sodium, instead of uranium? [link] [comments]  |
| Did all written language originate from a single early language? Posted: 29 Aug 2018 02:57 PM PDT or have different writing systems been created completely separately with no influence or knowledge of the existence of other written language? [link] [comments]  |
