Rates of Respiration for Different Carbon Sources
Saccharomyces cerevisiae, commonly utilized for fermenting in baking and brewing, is a eukaryotic fungus that can metabolize sugars for energy through cellular respiration. Fungi and animals share a common ancestor in the tree of life, which suggests studying single-celled yeasts is an effective way to identify and study complex systems in animal cells (Freeman, et al., 2017). S. cerevisiae was the first eukaryotic organism that had its genome mapped completely, is simple to maintain because of its small size and…...

Experiment Confirmed The Hypothesis
The hypothesis for this experiment was that Synsepalum Dulcificum would decrease the rating of sour taste in the foods. The data supported this hypothesis as the sour foods, orange, lemon and Sour Patch Kids, all had lower sour intensity ratings. This experiment showed just how the protein miraculin in the Synsepalum Dulcificum fruit worked. Once miraculin was bound to the sweet taste receptor T1R3, the sour foods tasted sweet.

Imaging by UV Fluorescence
Imaging by Ultraviolet (UV) fluorescenceSince the UV radiation has a short wavelengths than the visible light, so by using a UV-fluorescence, it is possible to identify multiple paint layers. Previous practical applications showed that the UV imaging is advantageous in detecting any retouching, varnishes, successive over-paintings and old restorations (Rizzutto et al., 2015). In fact, pigments usually show characteristic fluorescent hues when impacted to a UV light. For example, minium (Pb2O5) = orange fluorescence, while azurite = deep blue fluorescence,…...

Electrically Conducting Polymers: An Emerging Technology
Polymers have always been considered as being very good insulators of electricity. However around thirty years ago no one would have believed that polymers have the potential to conduct just as well as metals. But since then such accomplishments have been achieved through simple modifications of organic conjugated polymers. These new polymers are called electrically conducting polymers or synthetic metals', they combine the electrical properties of metals with the array of advantages that polymers possess. These advantages include lighter weight,…...

The idea of a self-luminescent stone without any form of excitation seems like something impossible. However, in 1603 that was what Italian cobbler cum alchemist, Vincenzo Casciarolo had encountered. He had found greyish bright and unusually heavy stones from the countryside around Bologna, Italy. After heating the stones in the air (this process is known as calcination), they had become fluorescent in the dark. Not only was the fluorescence astonishing, but it was also persistent (for years!). This was one…...
