If you cut entirely through the base of a tree but somehow managed to keep the tree itself perfectly balanced on the stump, would the tree “re-bond” to the stump or is this a tree death penalty? |

- Wikipedia and other sources say adult nuerogenesis (creation of new neurons in the brain) continues throughout life. But this new study in Nature says this is not true. What gives?
- How do solar panels work?
- Does salt used for snowstorms actually damage my asphalt driveway, and if so why?
- How can phytoestrogen consumption reduce menopausal symptoms in women but not alter blood androgen levels in men?
- Does the temperature of water have an effect on being able to put out fire?
- How do we know that the inverse square laws are not inverse "2 + epsilon" laws, where epsilon is too small to be detected by current detectors?
- How is the frequency in the european electric grid dropping to 49.996hz?
- Why does it take more effort to only close one eye than it does to close both eyes?
- How sure are we that our understanding of the fossil record of ancient megafauna (eg dinosaurs) is a result of their actual abundance vs sampling/survivorship bias?
- Would it be possible to measure the angular momentum of Sag A* by observing a frame dragging effect on the stars orbiting it?
- How do multi-drug-resistant bacteria maintain their resistance genes in the absence of selective pressure?
- Assuming the theory is true that a Mars-sized body collided with Earth causing the ejection of matter that would latter form the moon. How did the ejected matter circularize its orbit? Wouldn't the matter have fallen down to Earth?
- Is there a difference between receiving O negative blood vs your original blood type?
- Is there a reason why most electrical appliances with analog knobs (ovens and fans, for example) when turned on default to the highest intensity, and you need to keep turning the knob to reduce it?

| Posted: 12 Mar 2018 08:23 AM PDT so we have many sources out there which state that since the 1970's its been well established that adult neurogenesis is an ongoing phenomenon.
but this recent study says the opposite. So what gives? https://www.nature.com/articles/nature25975

| Posted: 13 Mar 2018 08:04 AM PDT In this review there are two statements:
And as noted earlier in the review:
[...]
I am hoping someone better acquainted with the literature and reproductive science could help connect all these dots for me. It sounds like phytoestrogens can exert some effects similar to that of estrogens, but in some cases don't exert those effects at all, or exert other unrelated effects. Some males express concern over the consumption of phytoestrogen-containing foods, e.g. soy, due to perceived risk of 'feminization' through increased 'estrogen' intake. To what extent does phytoestrogen act like an estrogen-analog in men? To what extent does it act like one in women? [link] [comments]  |

| How is the frequency in the european electric grid dropping to 49.996hz? Posted: 12 Mar 2018 02:39 PM PDT Tom Scot tells in his new video that its happening, stated in this this press release The statement doesn't answers mine and my SO's question how its happening. [link] [comments]  |

| Posted: 12 Mar 2018 06:33 PM PDT Do we have any controls that we can use to determine if a particular ancient megafauna was actually common? Is it possible the dinosuars we have fossil records of were more a result of them living in situations that lead to increased rates of fossil creation rather than them being common? Might dinosaurs have lived alongside vastly different kinds of animals that we just have no record of? [link] [comments]  |
| Posted: 12 Mar 2018 05:32 PM PDT Or are the orbits of the closest stars still too far, or is there too much complex interaction to make such a measurement? I found some abstract that mention other methods like hydrodynamic flow of stellar wind or something else that I don't understand. [link] [comments]  |
| Posted: 12 Mar 2018 04:36 PM PDT As a bioengineering grad student, I was taught early on that E. coli transformed with an Ampicillin-resistance plasmid would only maintain that plasmid in the presence of ampicillin; that in the absence of the antibiotic, maintaining the plasmid would cost too much energy and put them at an evolutionary disadvantage. How is it then that certain pathogens can maintain resistance to almost all types of antibiotics while not being exposed to them? [link] [comments]  |

| Is there a difference between receiving O negative blood vs your original blood type? Posted: 12 Mar 2018 03:56 PM PDT Essentially wondering if there are any up or downsides to receiving O negative when you are not O negative yourself. [link] [comments]  |

| What causes Ball Lightning, and have we made any recent discoveries on it? Posted: 12 Mar 2018 10:06 AM PDT Have we been able to reproduce it? From the footage I have seen, it looks to phase in and out instead of strike like typical lightning. [link] [comments]  |

| Axial precession and fixed stars? Posted: 12 Mar 2018 11:43 PM PDT How does the north star remain at a fixed spot in the sky, in regard to the earths axial recession? [link] [comments]  |
| Does dark matter lose energy via gravitational wave emission? Posted: 12 Mar 2018 04:05 PM PDT If so, when dropped around a gravity well (like a galaxy or a star) would it behave like a pendulum that eventually loses energy and settles down in the center? If not, is it just going to keep swirling around the center forever and never decay? [link] [comments]  |

| What is the maximum temperature water will reach in a microwave? Can it exceed boiling on a stove? Posted: 12 Mar 2018 01:33 PM PDT I was just microwaving my coffee for 30 seconds and suddenly wondered what's stopping water/liquid from reaching extremely high temperatures in a microwave? Thanks for any help! [link] [comments]  |
| Posted: 12 Mar 2018 11:04 AM PDT I figure that using a wrong password would return jibberish. How does the software determine that it's not the jibberish I wanted? [link] [comments]  |
