Does "Active Noise Cancellation" in audio products decrease ear damage by loud sounds? Posted: 18 Nov 2019 01:38 AM PST I've always wondered whether or not those "Active Noise Cancelling" earbuds actually helped in reducing the stress exerted on ears by earbuds/over-the-ear headphones. I know that using these headphones allows a user to enjoy audio at a lower volume (because the desired audio is not competing with the ambient), but does the anti-noise also contribute to hearing damage wrought by audio hardware? Also, on a separate note, can these "Anti Noise" frequencies be effective in a speaker format for a room or larger area? Thanks so much! submitted by /u/apoz11 [link] [comments]

Why Is Epinephrine Used With Lidocaine In Local Anesthesia Rather Than Norepinephrine? Posted: 17 Nov 2019 08:18 AM PST Maybe I'm just not understanding how the adrenergic receptors work. From what I read, beta-1 receptors are dominant in the heart, while beta-2 are dominant in vascular smooth muscle. Epinephrine works on both beta-1 and beta-2 receptors, while norepinephrine only works on beta-2 (edit: actually beta ONE). I have two questions about this: ​ When someone is given, say, epinephrine, how would you be sure that it binds to the correct receptors (in this case, beta-1)? I know epi is used in conjunction with anesthetics to cause vasoconstriction of the blood vessels, thus limiting the systemic spread of anesthetic. But how does this make sense? If epinephrine works on both receptors, and there are more beta-2 receptors in vascular smooth muscle, wouldn't the epinephrine cause vasoDILATION? Just insanely confused about this. Maybe my info is wrong, or maybe I'm not understanding how chemicals actually bind at the synapses. submitted by /u/lift_fit [link] [comments]

How does naloxone (Narcan) work so quickly? Posted: 17 Nov 2019 07:55 AM PST Anecdotally, people who've used naloxone on someone who has overdosed on an opiate say that it wakes the patient up immediately. The same thing was a plot point on [Insert Spoiler Show Name] recently: [Insert Character Name] had been given an overdose of heroin, and [Somebody Else] showed up to administer naloxone (intranasally) and [Character Name] woke up. I understand that opiate overdoses often kill by depressing respiration and perhaps heart rate, so I wonder: How does intranasal naloxone get where it needs to be, if respiration and circulation are slowed? If respiration has stopped (but only recently), will naloxone still work? What about circulation? submitted by /u/TwoNounsVerbing [link] [comments]

Why is it called the 'special' theory of relativity? Posted: 18 Nov 2019 02:21 AM PST I realize it only applies to special cases, but what determines those cases? I have found some contradictory answers. Some say it's because gravity can be neglected, and some say it's because it only describes events that unfold in inertial frames of reference. submitted by /u/21758102570 [link] [comments]

Do other mammalian new born babies go through night feedings like human babies? Posted: 18 Nov 2019 04:45 AM PST Or eat every few hours, or is it just humans? submitted by /u/jangooni [link] [comments]

What makes an element radioactive or not? Posted: 18 Nov 2019 06:42 AM PST I have a general idea, that the strong force is not evenly pulling the nucleons, but what causes the different types of radioactivity? submitted by /u/loudnon [link] [comments]

why did hepatitis B immunoglobulin efficacy decrease if given 12 hours after birth ? Posted: 18 Nov 2019 06:30 AM PST so, according to WHO, all babies that born from mother with positive hepatitis B antigen, should be given hepatitis B immunoglobulin (HBIG) in 12 hours after birth. why did it have to be administered in 12 hours after birth ? i read that if given more than 12 hours the efficacy will decrease, but i cant find why or how. submitted by /u/mytouw22 [link] [comments]

Does the movement of plates have any effect on the axial tilt of Earth? Posted: 17 Nov 2019 05:00 PM PST Since the continental and oceanic plates are constantly moving across the Earth's surface, does their movement have any effect on the rotational axis of the planet? If not, what can affect the rotational axis, and can this change over time? submitted by /u/the_shrinch [link] [comments]

If oysters and other bivalves are filter feeders, how are they not full of the more harmful pollutants that are present in many water sources, and how does this influence our consumption of them?

Do animals (such as snakes) that swallow their prey whole face any danger from their prey bursting from inside them? Posted: 17 Nov 2019 08:26 AM PST I saw a video on a subreddit of a fish swallowing another fish (about the same size as him) whole. Is that predator in any danger of its pray killing it from the inside? submitted by /u/Pjk125 [link] [comments]

Why aren't astronomers seeing these asteroids? Posted: 17 Nov 2019 10:09 AM PST We are always seeing on the news that some random space rock has passed closer to the Earth than our own moon, why are we only finding out about this as or after it happens. What is stopping scientists from seeing them ahead of time? submitted by /u/Da_Time_Traveler [link] [comments]

Do high frequency waves interact more than low? Posted: 17 Nov 2019 08:41 PM PST I've been reading that one of the largest hurdles in 5G distribution is that due to the high frequency the signal has a hard time navigating through walls, trees, people etc. My understanding is that the higher the frequency in this situation, the higher rate of interaction with it's environment; however, I can't reconcile this with my understanding of the waves at the further extremes of the spectrum, x-rays, gamma, and the like, which need inches, potentially feet, of lead housing to handle. Thinking about how the Earth's atmosphere seems to attenuate the high frequency radiations it makes sense that they in fact do interact more, but why then do we see the seemingly opposite effect with the necessity of lead boxes? I don't understand the seeming duality. submitted by /u/One-Lung [link] [comments]

Which isotopes commonly produced in nuclear accidents or bombs are primarily alpha emitters? Posted: 17 Nov 2019 06:51 PM PST I've been reading about the most common isotopes released at Chernobyl, and have so far only seen mention of gamma and beta decay. What isotopes would be prominent alpha emitters, and would these tend to also give off significant beta/gamma? submitted by /u/ppitm [link] [comments]

Why is no electric car producer considering a drop-in battery? Posted: 17 Nov 2019 11:14 AM PST Not sure if this got ask before, but with all the discussion about battery loading time, why don't we create a battery that can be pulled out of the car and exchanged for another one easily? submitted by /u/pdsbecks [link] [comments]

What is this new way to measure gravity? Posted: 17 Nov 2019 10:46 AM PST Found this article: https://bigthink.com/surprising-science/scientists-find-new-way-to-measure-gravity I'm having difficulty figuring out what it is about wave-particle duality they are measuring. What exactly are they measuring? How precisely? How big of a deal is this? (Explanations up to anything short of actual GR equations welcome. Undergrad level?) submitted by /u/martixy [link] [comments]

Why is strange matter supposedly infectious? Posted: 17 Nov 2019 05:55 PM PST From what I can understand, there's no evidence that strange matter exists or even could exist, so where do scientists get the hypothesis that if it did exist, it could infect regular matter and turn it all into strange matter? And why is it specifically strange quarks that supposedly have this property; why not charm matter, or top or bottom matter instead? submitted by /u/nilpotentOperator [link] [comments]
