[Biology/Ecology] How are buildings in Venice able to be half submerged in water, but mold-free and habitable? Posted: 17 Aug 2017 11:19 PM PDT Houses here get an inch of water from a broken pipe and they get black mold throughout the entire house. How is it possible that houses in Venice, often hundreds of years old, can have water literally lapping up onto the threshold, but you never hear about mold, mildew, or even building material erosion? submitted by /u/asgard13 [link] [comments]

How does a cooling system work? Posted: 18 Aug 2017 06:25 AM PDT I can comprehend a heating system, it can basically work by giving energy and heating the thing you want to heat. But how does a cooling system work, how can you reduce the energy inside the system by giving energy to it? submitted by /u/Pmmeauniqueusername [link] [comments]

How do satellites stay on their course? Wouldn't the slightes change make them slowly rotate off their path leading them into crashing down on to earth? Posted: 18 Aug 2017 05:48 AM PDT How do they stay up there? In my mind satellites need to like a 'perfect speed' just not to be too fast or too slow, but is that even possible? submitted by /u/TobitheRobot [link] [comments]

How is usable energy extracted from a fusion reactor? Posted: 18 Aug 2017 02:11 AM PDT A fission reactor ultimately heats water to produce steam to spin a turbine to generate electricity. I assume a fusion reactor ultimately heats water ....>>.... generate electricity. But how do we get from a hot plasma in a tokamak to heating water? How do we get from inertial confinement to heating water?? submitted by /u/RAAFStupot [link] [comments]

Can bacteria become cancerous? Posted: 17 Aug 2017 07:24 PM PDT So in this video about some kind of Japanese smoked fish they mentioned how the smoking helps preserve the fish by killing bacteria. Could it be possible that the carcinogens in the smoke (or generally in nature) could alter the genome of bacteria, becoming similar to cancer in humans? If so would a bacterial cancer cell have the same behaviour as a human one? Edit: forgot to add the main question, could this lead to a dangerous amount of bacteria growing in smoked foods? submitted by /u/vsprds [link] [comments]

Is there such a thing as space coordinates? Posted: 17 Aug 2017 04:48 PM PDT Let's say we wanted to broadcast some message into space, for possible detection by intelligent life anywhere. How could we communicate our location in the universe? submitted by /u/Farty-McFartface [link] [comments]

Is there any substance which is less toxic the more of it you consume? Posted: 17 Aug 2017 12:15 PM PDT As the title says, is there some form of poison or toxin which becomes less harmful the more of it is in your system? submitted by /u/c3n7uri0n [link] [comments]

What's the difference between anti bacterial and anti microbial? Posted: 17 Aug 2017 04:57 PM PDT I was thinking today about how some things are classified as "anti microbial" whereas others are "anti bacterial". Are these essentially the same thing? It seems like "anti bacterial" is used more medically. submitted by /u/schneidrew [link] [comments]

If someone quits smoking without having contracted cancer, do their odds of getting cancer eventually return to those of non-smoker? Posted: 17 Aug 2017 04:39 PM PDT Or has some irreparable biological damage been done, which increases the likelihood of cancer over time? Edit: my bad for typo in title :( submitted by /u/CaptainQueero [link] [comments]

How is lithium made in stars? Posted: 17 Aug 2017 10:39 PM PDT As I understand it hydrogen atoms brought together by gravity collide under high temperatures to create helium and release light and other forms of energy. Does this mean helium does the same to create litium? Or is it a mix of hydrogen and helium under great pressure and high temperature colliding to create lithium? If at all possible can you expand upon this and the reactions of the heavier elements that create even heavier elements in say our sun for example? submitted by /u/Phantompain23 [link] [comments]

Does a fish see clearly when out of the water? Posted: 17 Aug 2017 09:37 AM PDT Anytime I open my eyes underwater, everything is blurry, but I can see fine otherwise. Is it the same way for a fish?

Desiccated spruce branches will curl up or down depending on weather conditions, and have been used as artisanal weather predictors in Eastern North America. What particular properties does the structure of spruce branches have which makes them behave in the way they do? Posted: 17 Aug 2017 05:27 AM PDT Reference: http://survinat.com/2014/02/spruce-barometer/ I'm particularly curious about what, in the wood structure, induces such a specific directionality to this behavior. submitted by /u/Gargatua13013 [link] [comments]

How do scientists stop the environment from causing wave function collapse when doing QM experiments? Posted: 17 Aug 2017 01:26 AM PDT My assumption has always been that things like the double slit experiment must be performed in a vacuum to prevent the air from interfering with the electrons being fired. However, is it possible to completely prevent ALL particles from contaminating the environment? For example photons emitted from the equipment, stray cosmic rays, etc? How is this overcome? submitted by /u/barroon_animar [link] [comments]

Did trees bear fruits before there were mammals to eat them? Posted: 17 Aug 2017 06:32 AM PDT As per my understanding (which is limited), fruits exist so that mammals will eat them and spit out the seeds far away from the parent tree, spreading the seeds around. Because of this, would it be biologically viable/possible for fruits to exist before mammals had evolved to the point where they could eat them? submitted by /u/PredatorSane [link] [comments]

How much more energy will fusion of lithium-6 deuteride release than fission of uranium-235? Posted: 17 Aug 2017 12:04 AM PDT In terms of thermonuclear bombs, the secondary stage (comprised of 6LiD which is compressed and heated to induce D-T fusion) supposedly releases many times more energy than the primary stage (comprised of a supercritical mass of U-235 or plutonium with a small amount of deuterium and tritium to boost the explosion) despite there not being a whole lot more material. If you have, say, 1kg of U-235 that undergoes fission and 1kg of 6LiD used in a fusion reaction, how much more energy will the fusion release than the fission? I've heard that it's around 7x more but I can't be sure. submitted by /u/Ambidextroid [link] [comments]

How was helium discovered? Posted: 16 Aug 2017 08:09 PM PDT This question bridges history and chemistry but I'm wondering if anyone has better information about the history of Helium's discovery. Did Janssen and Lockyer work together to determine that the yellow line was proof of a new element? And how did Frankland factor in? Did Langlet and Cleve isolate Helium from Uranium ores or did Ramsay? Did two independent discoveries occur at roughly the same time? How controversial was the yellow line discovery? Did most or all of the scientific community accept that as proof of Helium's existence? submitted by /u/JTanCan [link] [comments]

Posted: 16 Aug 2017 08:43 PM PDT I'm assuming later in pregnancy you can just look for the obvious penis vs. no penis, but in the earlier stages, how can the doctor tell? Is the penis just harder to spot by the untrained eye or are there other ways of knowing? (I tried Googling the answer but the results but the results were all worthless mommy blogs.

How does a computer network like HBO's handle the massive output of data for short bursts of time, like a GoT episode? Posted: 15 Aug 2017 08:25 AM PDT HBO but have to stream massive amounts of data for about an hour when the episode is first up followed by a percipitous drop-off in usage.

How complex can 'nuclear molecules' get? Posted: 15 Aug 2017 08:24 AM PDT In the 'hard' science fiction book 'Dragon's Egg' by Robert Forward, there is an intelligent species that evolves on the surface of a neutron star, using nuclear interactions to store energy, consume food, have thoughts and immune systems, etc, instead of chemical/electron interactions as life on Earth does. Putting aside the question of how likely this would be or what barriers the magnetic field might pose - how complex can nuclear interactions get? Is there anything equivalent to the element carbon and the rich diversity of molecules it spawns, in a nuclear setting? Are there any realistic candidates for nuclear ATP, DNA, proteins, etc? submitted by /u/zelmerszoetrop [link] [comments]
