How do these geared secateurs work? Posted: 27 Jul 2018 01:49 AM PDT I have these geared secateurs, and they have a gearing mechanism which I don't understand.

Are the gears affecting the power of the shearing motion, and if so how?

Megathread: buried lake detected near Mars's south pole Posted: 25 Jul 2018 11:35 AM PDT Radar data from the European Space Agency's Mars Express spacecraft have revealed that a buried lake of liquid water could exist near the south pole of Mars. This lake would be around 20 km wide and 1.5 km under the surface. This discovery has been announced today by a cooperation of Italian researchers from various universities and laboratoires. The history of water on Mars is complex but this could be the first evidence of liquid water still existing on the red planet. Several of our planetary science panelists will be in the comments to help answer questions you may have on this announcement.

AskScience AMA Series: We have made the first successful test of Einstein's General Relativity near a supermassive black hole. AUA! Posted: 26 Jul 2018 05:00 AM PDT We are an international team led by the Max Planck Institute for extraterrestrial physics (MPE) in Garching, Germany, in conjunction with collaborators around the world, at the Paris Observatory-PSL, the Universite Grenoble Alpes, CNRS, the Max Planck Institute for Astronomy, the University of Cologne, the Portuguese CENTRA - Centro de Astrofisica e Gravitacao and ESO. Our observations are the culmination of a 26-year series of ever-more-precise observations of the centre of the Milky Way using ESO instruments. The observations have for the first time revealed the effects predicted by Einstein's general relativity on the motion of a star passing through the extreme gravitational field near the supermassive black hole in the centre of the Milky Way. You can read more details about the discovery here: ESO Science Release Several of the astronomers on the team will be available starting 18:30 CEST (12:30 ET, 17:30 UT). We will use the ESO account* to answer your questions.

Do the signals of multiple cones/rodes share the same pathway in the optic nerve? Posted: 26 Jul 2018 12:18 AM PDT My question was formed when looking into this picture. The rightmost ganglion receives signals from 3 rods and a cone. Which would means the fiber starting from that ganglion would signal "on" on a mix of the cone's and the rods' signals. This is not necessarily bad but it does change how "post-processing" in the brain would have to work. There is a difference between having ~1million signals of one of the cell types (L, M, S, R) and having to deal with signals that are a combination of those. Just curious, does that kind of "promiscuity" of ganglion and/or bipolar cells actually exist? or was it just an oversight by the artist? P.S. looking at numbers of cells alone there needs to multiple photosensitive cells connected to the same fiber since there are ~6 times more photosensitive cells than fibers. So the question is specifically about "cross-signals". Having 6 L cones connected to the same ganglion is a given, can we have a ganglion connected to 2 L, 2 M and 2 S cones? it seems to be inefficient from a "data processing" viewpoint, but the lower cost in "infrastructure" (the amount and organization of bipolar cells) might offset this. submitted by /u/hidetzugu [link] [comments]

Other than regulating pH (and providing a medium) what are the roles of buffers in gel electrophoresis? Posted: 25 Jul 2018 09:05 PM PDT I've read that buffers are needed to generate an electric field such that the SDS-treated protein, or DNA, can move towards the cationic electrode. This seems strange, and I'd like to understand it better. Wouldn't the electrostatics between the cationic electrode and the DNA or protein be enough to pull the desired molecules through the gel? I understand that this isn't the case, but don't understand why. Thanks so much for your time and help! submitted by /u/RadiantStars [link] [comments]

How can entropy increase? / help me understand entropy Posted: 25 Jul 2018 05:15 PM PDT i've heard several definitions of entropy, but the first to make sense is wikipedias; entropy is a number that is derived from the number of microstates of a system with some math applied. if i understand what a microstate is, it's just a possible configuration, like a 10x10 grid with an object on 1,1, another microstate could be the object on 4,9. given a finite system, how could the number of possible configurations ever increase let alone decrease? wouldn't it just be constant? the only way i see to change entropy is to change the scope of the system; if the grid shrinks to 9x9, the entropy drops from 100(+-math) to 81(+-math), conversely, if you increase the grid to 11x11, you get more possible configurations. how does that work for the universe though? how can the total universal entropy increase if the number of things in hte universe is finite? A fair bit of this is probably off. i've only ever seen entropy as a chart to memorize for chemistry, but i want to understand it. if that's too broad of a request i'd be happy with links to videos or articles that explain it submitted by /u/potatotate_spudlord [link] [comments]

Why does dew not condense on items under a cover?

Will water freeze if it can't expand? Posted: 24 Jul 2018 10:02 AM PDT I know that water is essentially incompressible, and actually expands by ~10% when it freezes. But what if it's not allowed to do that? Like, imagine I had a watertight container made of steel, or some other material that's sturdy enough to not buckle under the force of expanding water. What if I filled it to the brim with water, sealed it shut, welded the seams for good measure, and stuck it in the freezer? I know that the reason Earth's inner core is solid is because the pressure created by the entire planet's mass pressing down on it is so strong that it prevents the core from melting. Would the same principle apply to the water in my container and keep it mostly liquid? Or would I get some weird and exotic form of ice?

Occasionally we'll get a storm of tropical origin that moves up the coastline. Lately, for three or four days, there have been scattered storms moving from southeast to northwest.

What do we actually see when we look at the cosmic microwave background? Posted: 24 Jul 2018 11:42 AM PDT I was thinking about the cosmic microwave background and the earliest stars and how far we can see, and it occured to me, that if the CMB is the oldest and farthest thing we can see and looking as far as we can into the night sky is like looking into the past of the universe's history then are we basically looking at the relic radiation of some of the particles that we are made of? If that is the case, does that mean that we could basically see every intermediate step of star formarion etc. up to the point where our own star is forming in a gas cloud, given that we look at the right spot and the right distance (e.g. 13bly, 10bly, 7bly etc. away)?
