Probiotics are "good" bacteria sold in pharmacies, to be taken alongside antibiotics to protect your intestinal microbiome. How are they manufactured? How can a powder contain live bacteria? How do they survive without food in a paper envelope for years? Posted: 11 Aug 2017 03:19 PM PDT Probiotics are live bacteria to be taken alongside antibiotics to protect your intestinal microbiome, as antibiotics often indiscriminately kill both "good" and "bad" bacteria. They are typically sold as a powder you're supposed to dissolve in water and then swallow. How are they manufactured? How can you turn bacteria into a powder (without killing them)? They typically have an expiration date of 3 to 5 years in the future. How can the bacteria survive all this time without any food? How come they don't reproduce until they're eaten by us? I can only assume they are somehow "frozen" (biologically inactive) until eaten. If that's the case, how does that work and how can they eventually "come back to life"? submitted by /u/RainbowDoc [link] [comments]

Why is autism more common in boys than girls? Posted: 11 Aug 2017 06:39 PM PDT I've read that autism is 4x more common in men than women. Is this a fairly concrete fact, and if so, do scientists have any intuition why this is the case? submitted by /u/darkostwin [link] [comments]

Would it be possible to project and therefore understand better the geometry of a 4-dimensional object with a 3-dimensional display? Posted: 11 Aug 2017 04:15 PM PDT It is (obviously) possible to depict a 3-dimensional object on a 2-dimensional screen so using this same principle wouldn't it also be possible to depict a 4-dimensional figure on a display that uses 3-dimensions? submitted by /u/Deadshot_0826 [link] [comments]

Does the same food have the same amount of calories as it is cold when it's hot? Posted: 11 Aug 2017 01:54 PM PDT Ex. Does a frozen pizza have the same amount of calories before it goes into the oven as it does after? submitted by /u/ifailinstyle29 [link] [comments]

What is the difference between a conventional weapon's recoil compared to a railgun? Posted: 11 Aug 2017 01:27 PM PDT By conventional weapons I mean things like guns using bullets or shells, using a chemical propellant. I know that the propellant explodes which causes an expansion of hot gas which pushes the projectile out the end of the barrel with the same amount of force as the weapon recoils (by Newton's Third Law). But what about railguns that use electromagnetic induction instead? Since there is no explosion, does that mean there is no recoil? Does Faraday's and Lenz's Laws apply at all? submitted by /u/lordplane [link] [comments]

Does color affect non visible light? Posted: 11 Aug 2017 11:04 AM PDT So I know that when we see color, it is the result of light striking that object and being reflected at a specific frequency. But does an object color also affect other forms of light besides visible? For example, would shooting a gamma ray at something orange differ the resulting wavelength from shooting it at something purple? submitted by /u/at_chan [link] [comments]
