Researchers develop microrobot designed to deliver stem cells via intranasal pathway - 0 views

  •  
    They are undifferentiated cells capable of being anything. You might know them as stem cells and now a robot can take them up your nose into your brain. "Researchers have developed a stem cell-based microrobot called "cellbot" capable of delivering stem cells to the brain via intranasal passage using a minimally invasive method. The cellbot has the potential to become a key player in the treatment of neurological disorders such as brain cancer, Parkinson's disease and Alzheimer's disease."

Astronaut makes zero-g tacos with 1st chile peppers grown in space. They look delicious... - 0 views

  •  
    "NASA astronaut Megan McArthur created what she called "my best space tacos yet," using some of the newly harvested peppers, some fajita beef and rehydrated tomatoes." They missed the mark not using sustainable fajita beef made from plants or a space cow but 'locally' grown space peppers could become a big hit at Whole Space Foods.

Lesson Three: Ammonia and Chloramine - Safe Drinking Water Foundation - 0 views

    DRIVER-TREATMENT-WATER-INFRASTRUCTURE-CHEMISTRY-CHLORAMINE One new option that communities with ammonia problems have is biological filtration. This is a safe, chemical-free, method of removing ammonia. In a biological filtration facility, one of the stages of filtration is to pass the water through a special filter that is full of nitrifying bacteria. These bacteria take in the ammonia and some oxygen and perform a bio-oxidation reaction. They oxidize the ammonia into nitrite NH3 + O2 -> NO2- + 3H+ Then further oxidize that into nitrate, NO2- + H2O -> NO3- + 2H+. The bacteria gain energy from these reactions and are specialized to do them very efficiently. This process is part of the natural nitrogen cycle and does not produce any harmful byproducts. The nitrate that is produced by this process can easily be removed from the water by the reverse osmosis membrane in the final stage of the filtration process. The reaction between chlorine and ammonia can be written as NH3 +HOCl -> NH2Cl + H2O. In this chemical equation, NH3 is ammonia and HOCl is hypochlorous acid which is formed when the chlorine is first dissolved in the water. The primary result of this chemical reaction is NH2Cl, a chemical known as chloramine. Chloramine is a disinfectant like chlorine, it is a weaker disinfectant than chlorine but it lasts much longer in water. The chlorine concentration in water can gradually decrease as the chlorine evaporates out but chloramine does not do this. This makes it useful for making sure water stays disinfected throughout drinking water distribution systems. In areas where there is no, or very little, ammonia in the raw water treatment facilities might still want to use chloramine for this purpose. After chlorinating (disinfecting) the water, as the last step in the treatment process, they add ammonia and more chlorine to the water so that they react and create chloramine.

3D-printed steak, anyone? I taste test this 'gamechanging' meat mimic | Food | The Guar... - 0 views

    Wow, check out the picture of the Meat 3-D printer on this article. "The "meat" is 3D printed, and the mimicry is extraordinary. The molecules of difference that create the flavour of beef, as distinct from that of lamb, are few but extremely powerful. This is certainly the closest synthetic approximation yet."
