| Why do female lions kill the cubs of a pride mate? Posted: 01 Sep 2017 06:25 AM PDT Hello! I was re-watching the Savage Kingdom, a documentary which shows what you might expect from an African wildlife program but is narrated as though it's some epic drama. Most of the scenes however are what you usually see. Predators hunt prey, drink water, establish territories, etc. However, in the first episode the supposed dominant female in a pride mates with the male and gives birth to cubs. Two weeks after birth, the other lions find them and start to violently thrash them and then eat them. All the time, the mother is clearly distressed but makes no attempt to stop the others. The show never attempts to explain it other than 'This is not cruelty on the lions part, this is simply how lions behave'. However, I found it hard to understand the logic of it. I 100% understand when in the same episode a lion kills a leopard cub. They perceive leopards as competition or a threat to their young, so they kill them whenever possible and the cubs cannot defend themselves. I also understand if a new male comes in and kills the female's offspring so they go back into heat and are ready to mate with him. I could even rationalize if it was a rival female seeing new cubs as a threat to her own pride. However, I do not understand why they would kill the offspring of their own pride-mate and supposed superior. My friend and I came up with the following theories regarding it, but none seem to stack up.
So tl;dr, a female lioness who is supposedly the highest ranking female gives birth to cubs away from the pride. Two weeks later the pride finds her, takes the cubs and violently thrashes them, then begins to eat them as they kick and cry out. All along the mother, while clearly distressed, does not attempt to stop her comrades. [link] [comments]  |
| Posted: 01 Sep 2017 07:55 AM PDT Amplitude of S1 = A, Intensity = I Amplitude of S2 = 2A, Intensity = 4I I know when the 2 beams are polarized in the same plane, the intensity varies sinusoidally between I (destructive interference) and 9I (constructive interference). But what if the beams are polarized in mutually perpendicular planes? A constant 5I? If the intensity is not constant, then that is the resultant intensity when they meet in phase and out of phase?

| How do we calculate current world population? Also, how accurate is that count? Posted: 31 Aug 2017 02:56 PM PDT Burning question on my mind for awhile now. How do scientists calculate the current number of people on the planet? Is it some massive database, clever guesstimation, or something else? [link] [comments]  |
| When a subsea cable is damaged, how do internet companies know the location where the fault occured? Posted: 01 Sep 2017 01:43 AM PDT Intriqued by this article: https://www.itnews.com.au/news/aussie-internet-pain-after-asian-subsea-cables-cut-472070 I asked myself how can they possibly know where the damage is? I mean, with a "normal" cable/wire you can just know if the cable is cut or not, not where it's cut. Do subsea cables have some kind of transmitters installed in them at interval lengths to help narrow down any faults? [link] [comments]  |

| Why are trees in the Sahara flat and wide? Posted: 31 Aug 2017 08:18 PM PDT I understand it is a certain species that grow like this, but how is it beneficial to the tree? It seems like it is very important to the animals because of how much shade is provides, but wouldn't the increased surface area on top create issues with more of the tree being exposed to direct sunlight?

| Why do some seagulls have messy feathers small necks and are very aggressive? Posted: 01 Sep 2017 07:39 AM PDT Sorry if the title is confusing it's just I always see the occasional 'alpha' looking seagulls. That's wider than others shorter with small necks and have messy feathers. Also they always sqwuack at the innocent ones trying to get a piece of the pie. [link] [comments]  |

| When a boat travels over a water bridge, how does the weight on that bridge change? Posted: 31 Aug 2017 04:21 PM PDT Inspired by this picture, I wanted to know if the weight on the bridge would be lighter or heavier while a boat was traversing. My assumption was that it would be lighter, from displacement. Furthermore, how heavy (as a percentage of the weight of the existing water) could a ship be before it sank or high-centered on the bridge? [link] [comments]  |
| How do animals that consume venomous creatures metabolize the venom glands? Posted: 31 Aug 2017 11:09 AM PDT I just watched this video that National Geographic posted: https://tinyurl.com/ybosw7pg It depicts a rooster attacking and consuming a cobra. I'm curious about how the bird metabolizes the venom. Even if it hasn't been bitten, wouldn't eating the entire animal (specifically the venom gland) be deadly? [link] [comments]  |
| Is there a front side to a spiderweb? Posted: 31 Aug 2017 03:15 PM PDT For several days I've been watching a big ol' spider that has spun a large web on my back porch. Every time I go out to check on the spider it's on the side of the web facing away from the house. Do spiders naturally favor one side of their web over the other side? Is there a front side and a back side? [link] [comments]  |
| How do we determine the half-life of U-238? Posted: 31 Aug 2017 08:20 PM PDT From the Institute for Energy and Environmental Research's website: "Uranium-238, the most prevalent isotope in uranium ore, has a half-life of about 4.5 billion years; that is, half the atoms in any sample will decay in that amount of time." The key word I'm looking at here is 'any'. So if you had a sample of two U-238 atoms and wanted to watch it decay, how would you know its half-life if it would take 4.5 billion years? If one watches the neutrons decay individually over time from one atom of U-238, how long would it take before you see the first neutron decay, allowing you to extrapolate the half-life? Can you please show your math and how you got to that conclusion? Thank you. [link] [comments]  |

| Is it possible to make a 100kW nuclear reactor that's not an RTG? Posted: 31 Aug 2017 11:51 AM PDT I'm looking up "small nuclear reactor" and mostly finding that "small" means "enough to power 50,000 homes". Outside of an RTG, is it possible to go small enough to make a nuclear powered range extender for an electric vehicle? Or are there constraints on the minimum size of nuclear power?

| Posted: 31 Aug 2017 10:39 AM PDT And if there is a way of measuring the standard deviation, what are the implications of it? My understanding of evaporation is that the higher energy molecules escape the liquid even though the overall temperature is below the boiling point. If the standard deviation of the temperature is lower, would that imply that evaporation would occur at a slower pace? [link] [comments]  |

| Would we be able to see geological evidence of a Harvey-like event from 1,000 years ago? Posted: 31 Aug 2017 06:18 PM PDT Given that Hurricane Harvey is being described as a "1,000 year event", do we have any way of seeing if there was a hurricane with flooding of a similar magnitude in the past 1,000 years based upon geological or ecological evidence?
