Why are scientists trying to manufacture organs in space? https:///3hd15At Gravity can be a real downer when you are trying to grow organs. That’s why experiments in space are so valuable. They have revealed a new perspective into biological sciences, including insights into making human tissues. Gravity influences cellular behavior by impacting how protein and genes interact inside the cells, creating tissue that is polarized, a fundamental step for natural organ development. Unfortunately, gravity is against us when we try to reproduce complex three dimensional tissues in the lab for medical transplantation. This is difficult because of the intrinsic limitations of bio-reactors used on Earth. I am a stem cell biologist and interested on brain health and evolution. My lab studies how the human brain is formed inside the womb and how alterations in this process might have lifelong consequences to human behavior, such as in autism or schizophrenia. Part of that work includes growing brain cells in space. Growing tissue and organs in the lab To build organized tissues in the lab, scientists use scaffolds to provide a surface for cells to attach based on a predetermined rigid shape. For example, an artificial kidney needs a structure, or scaffold, of a certain shape for kidney cells to grow on. Indeed, this strategy helps the tissue to organize in the early stages but creates problems in the long run, such as eventual immune reactions to these synthetic scaffolds or inaccurate structures. By contrast, in weightless conditions, cells can freely self-organize into their correct three-dimensional structure without the need for a scaffold substrate. By removing gravity from the equation, we researchers might learn new ways of building human tissues, such as cartilage and blood vessels that are scaffold-free, mimicking their natural cellular arrangement in an artificial setting. While this is not exactly what happens in the womb (after all the womb is also subject to gravity), weightless conditions does give us an advantage. And this is precisely what is happening at the International Space Station. https:///3hd15At

in 2018, Google presented a super-quick method of making another Google Docs document from anyplace in a program. Composing in docs.new in the URL box makes another archive. Sheets.new begins another spreadsheet. Keep.new makes another note. Etc. Presently you can utilize a similar stunt to begin a Hangouts Google Meet call from any program. Simply type in meet.new in the URL box and you’ll promptly make another room and be furnished a URL to impart to other people. The component update was tweeted out by G Suite VP Javier Soltero today: Read the full post: http://gootech.com.ng/?p=187

There is this new s*x position that people are talking about now – its called the Cowpoke. The position, which is intended to give maximum comfort and pleasure for the woman, has the woman on top – and the man on the bottom – with his legsup. Because the man is in a legs-up/submissive position, some men are not comfortable getting in this position read more http://www.decentgist.com/2017/06/men-are-refusing-to-try-out-this-new-sx.html |

It’s no secret that eating yogurt is healthy for you. By now, you’ve probably heard of those beneficial probiotics this tasty snack delivers. They’ve been touted for everything from relieving digestive problems to boosting your immune system. But, did you know that getting a daily dose of probiotics by adding yogurt into your diet could be one of the best things you can do to boost your brain health? That’s because your nervous system is actually made up of two separate systems: your central nervous system and your enteric nervous system. The gut-brain connection Your central nervous system is your brain and spinal cord while your enteric nervous system is associated with your gastrointestinal tract, your stomach and intestines. These two systems are directly connected via your vagus nerve. This means that what damages one system can damage the other and what makes one system healthy, makes the other healthy as well. In fact, the vagus read more http://www.decentgist.com/2017/06/brain-booster-found-in-your-refrigerator.html |

Enjoy!!! ADETUTU ``` I have heard of the dancing echoes To the drumbeat of your heart When I listened with my turtle ears As they pierce through my hollow chest. I can see how the crest of your eyebrows fall; calling in rhythm of trailing silence O, I was there, when mighty knights lost their treasures in wishes for your dangling smile. I know, the stairs of your shoulders Are gods-bestowed to rise your beaut Above everyman's pride in spite of their flaunts Ah! Chants of eternity beseech your cherub's voice. ADETUTU I have heard of merchants who priced your beading waists as they passed along the tunnels to read more here -=== http://www.decentgist.com/2017/05/poem-by-el-cypheradetutu.html |
