| What are the effects of the smoke generated by the fires in Australia? Posted: 04 Jan 2020 07:39 PM PST I'd imagine there are many factors- CO2, PAH, soot and carbon, others? [link] [comments]  |

| Posted: 04 Jan 2020 09:26 PM PST A friend of mine randomly decided to tell me that ants don't and/or can't sleep but then said even more interestingly that they do not have lungs, so my question was, how do they breathe? She said though their movements but how does that work?? [link] [comments]  |

| What makes a soap a "germicidal" soap? Posted: 05 Jan 2020 01:09 AM PST I mean, since all soaps are meant to rid surfaces of organic, non-polar molecules, shouldn't they work equally since all bacteria and viruses are made of organic, non-polar molecules? [link] [comments]  |

| When we say a species is older than dinosaurs what do we mean by that? Posted: 04 Jan 2020 05:45 PM PST I saw a post today about the lamprey fish, and how it's older than dinosaurs. What does this mean, it's not that this species has remained genetically the same millions of years that one could reproduce with an individual from that long ago, surely it's evolved so much by now that it would be considered a different species even if it looks similar. So really all species are older than dinosaurs as they all stem from before dinosaurs? [link] [comments]  |

| Can an asteroid (iron or rock) be so old it can't be dated with our current testing methods? Posted: 04 Jan 2020 05:28 PM PST If an asteroid had been traveling across the Milkyway galaxy from when it first formed and passed through our solar system and we were able to get samples from it, is it possible that it can be so old we can not date it? Oumuamua comes to mind. What would the oldest date we could determine with current testing methods? [link] [comments]  |

| How do auto manufactures avoid RF interference with adaptive cruise control systems? Posted: 04 Jan 2020 06:02 AM PST Do other radar systems interfere with each other in the allotted band? For example, could Tesla's adaptive cruise system interfere with another car that has a similar system in the same vicinity? [link] [comments]  |
| Why do some people think cilantro tastes like soap? Posted: 04 Jan 2020 09:13 AM PST According to articles I've found, up to 14% of the population is repulsed by cilantro, claiming it tastes like soap. This apparently has a genetic component, although the specific genes involved seem to be complicated. My question is about how these genes affect taste receptors or the brain to make the subjective experience of tasting cilantro differ so much between two different groups. [link] [comments]  |

| How do high voltage power lines simultaneously have high voltage and low current? Posted: 04 Jan 2020 12:07 PM PST It is pretty straight forward that decreasing the current flowing through a transmission line also decreases the loss of power from transmitting through that line due to: P = I^2*R P: Power Lost I: Current R: Resistance Every source that I have found states that current is decreased in long distance power transmission by using increasing the voltage. Why doesn't this idea conflict with ohms law? V = I*R V: Voltage If the voltage is increased shouldn't the current also increase, not decrease? Thanks! [link] [comments]  |
