Hello everybody ! My 17 years old daughter and me are interested in buying a microscope with enough power to be able to (let's say it that way) "see some cells in action and distinguish its parts, and also some bacteria and so on." I know that it largely depends on the size of the different cells, bacterias and other subjects  etc (I suppose virus are too small to see... I wonder if searching a microscope around 150€ is a good try, and if a good second hand one could be a better option to have a better one than a brand new but less powerful one.   Do you have any specific brand or mo ..read more

I've selected protease as the optimal enzyme for eliminating gluten formed from flour. Could you please provide insights on the best enzyme for removing gluten, dosing methods, and how to identify the suitable enzyme variant given that proteases have diverse types? This information is essential for my project aimed at resolving pipeline blockages induced by gluten from flour in the food industry using enzymes ..read more

Hi.  Are different tree species graft-compatible if one of these classifications coincide ?  Or has to be an specific one ?  Or more than one ?  Or that is not it ?   Example:  Can Apricots and peaches be cross grafted because  both share a bunch of clades and more ?  If they coincide in only one of the clades; are they compatible ?   How is it known ..read more

At the nursery, the trees they sell are labeled as 'fruiting' , 'flowering' , 'shading'  What are the 'flowering' ones biological purpose ?  Are these somehow manipulated trees; or their flowers have no stamen, stigma, no reproduction purpose ?  Those do not bear fruit.  (Like the ornamental cherry blossoms) How does it work ..read more

Well they say by figuring out the exact structure of a protein could sometimes take years and millions of dollars. Why does it take so long to study proteins or the exact structure of a protein? They also say it takes millions of dollars and very long time and meaning scientists were only able to study a tiny fraction of them. This slowed down research to tackle disease and find new medicines. Why does it take so long to find the exact structure of a protein?     ..read more

There was a video I will have to see if I can find it, they are printing 3D organs like a liver or kidneys so on. This got me thinking like how long before doctors and scientists can use 3D printed organs to replace bad or dying organs in the body? Is this some thing 10 to 15 years out before they have 3D printed organs? What are the problems holding them back? I thought one of major problems they had is how to connect every thing and supplying the blood and nutrients to the organ.      ..read more

Just how complex are the human body cells, tissue and organs? What is the best way to visualize the complexity of human body cells, tissue and organs? Are cells like ultra small factories and organs like ultra small cities if one is to visualize the complexity or is it more complex than that?         ..read more

Various people have said it would be possible for people to fly with strapped-on wings if they were in a low gravity environment like the Moon (and assuming the air pressure was about the same as on Earth). Okay, I'm certainly willing to believe that, but I want to know how this would work. Is it simply a matter that people could produce enough thrust with the wings to lift themselves into the air once they reached a certain low weight?  (For the sake of argument, let us assume a 4-meter wingspan and about 4 square meters of wing surface.)  I'm not sure I could flap my arms fast enou ..read more

One of the most often sighted cryptids and or sea monsters is the sea serpent, sailors, for centuries, gace reports of giant sea monsters that were large enough to endanger their ships and other wise scare the bejesus out of otherwise brave men. Some of the examples were the giant squids, now days we know that giant squids exist, maybe not as big as reported but still big enough to be monsters. Sea Serpent sightings are now days thought to be the result of Oarfish being mistaken for Sea Serpents but there are sea serpents alive today, real snakes that live in the sea, one of which is repu ..read more
