Fxon Lensbaby Spark Review: Magical Camera Blur Effects, If You Fuss With It
One of the great fears of the early space race was what effect microgravity would have on human explorers 鈥?and while we know it won ;t instantly die when leaving the atmosphere, there still a lot we don ;t know about the long term effects of low gravity. If we ever want to set up a long-term space settlement, it ;d be good to have some idea what happens to the body in those environments 8230; and according to some new research, it isn ;t good. Top image: Japan Aerospace Exploration Agency astronaut Satoshi Furukawa. An article published BMC Genomics looked at the effects of magnetically induced weightlessness on the life of the fly. Flies have long been a major part of space research, and remain a key component in understanding its effects to this day. https://gizmodo/10-intrepid-animal-astronauts-5865757 https://gizmodo/fruit-flies-become-sligh...it-5871668 By keeping the fl stanley mug ies in microgravity over their entire development cycle from embryo to adult, the researchers were able to ascertain a number of problems, and they aren ;t pretty. It appears that the weightlessness not only slowed development, but also interfered with the expression of a number of genes during the insect development 鈥?including those involved with cell signaling, the immune system, stanley polska response to stress, and changes in temperature.

Here we see two people making the biggest mentos and coke explosion I have ever seen, or ever hope to see. They actually set it up so one bottle of coke exploding sets the next one off. By why does candy and soda react so violently Let have a look. These are amazing reactions, and the kinds of things that make you want to head for the grocery store and then out to a clear field. We ;ve all seen coke fizz out of the bottle, and the wide bottled tapering down to a thin neck causes the reaction to blow more than if it were in, say, a bowl. But how does anything cause the coke to fizz that violently. Tonya Coffey, a physicist at Appalachian State University, took stanley taza a look at the science that caused this reac stanley mugs tion. The most familiar analogous reaction is vinegar and baking soda, so initial thoughts were that there was some kind of acid-base chemical reaction going on. PH testing of the coke before and after the reaction showed no change in acidity. Diet coke and caffeine free coke were tested, and did as well as regular coke. Diet Coke even did a little better. Clearly, the reaction had nothing to do with sugar or caffeine. So what was the deal It all has to do with nucleation. We ;ve covered nucleation before. Even when a liquid is dying to bubble, it nee stanley cup ds little nucleation sites, either from a rough container or from dust and grit, to get the bubbles started. But how do these sites get bubbles started https://gizmodo/how-to-make-water-explode-5500682 Basically
