Un tono rojizo, llamado airglow, llena el cielo sobre el Telescopio Submilimétrico Sueco / ESO retirado (SEST) , ubicado en el Observatorio La Silla de ESO en el norte de Chile. El inconfundible resplandor verde de un cometa distante, la majestuosa Vía Láctea y las Nubes de Magallanes adornan el cielo nocturno en esta imagen panorámica equirectangular.

🔥SAUNA🔥 my favorite way to end a workout! . . fun facts: using the sauna 4-7 days a week has been proven to decrease all-cause mortality by 40% (of course over a long period of time). Heat stress has also been shown to prevent damage in proteins, which is one of the leading causes of aging. . . #sauna #saunabenefits #lafitness #fitness #fitnessmotivation #thedailysculpt #sculptsquad #health #healthy #biology #chemistry #gym #fit #drrhonda

Esta impresionante imagen muestra el centro de la Vía Láctea. está lleno de características inducidas por el polvo que obstruyen las observaciones científicas, pero se ven tan hermosas que es difícil recordarlas demasiado.

______________________________________ 🇬🇧/🇺🇸A neodymium magnet (also known as NdFeB, NIB or Neo magnet), the most widely used type of rare-earth magnet, is a permanent magnet made from an alloy of neodymium, iron and boron to form the Nd2Fe14B tetragonal crystalline structure. Developed independently in 1982 by General Motors and Sumitomo Special Metals, neodymium magnets are the strongest type of permanent magnet commercially available. ________________________________________________ #q_science #science #қазақғылымы #physics #chemistry #mathematics #research #nerd #наука #исследование #химия #физика #математика #ғылым #quantum #quantumphysics #quantumchemistry #teaching #квантоваяхимия #wildworld #kazakhstan #kazakhstanscience #қазақстан #kaznu #kaznu_physcat #казну #chemfac_kaznu #нишфмн #ниш #нишфмналматы

Speaking at #GYSS2019 this morning, 2010 Millennium Technology Prize winner Professor Michael Grätzel shared the inspiration behind his invention of high-efficiency and low-cost solar cells, and how they have evolved from the first prototype in 1988 to being used in most large scale industrial applications today. Taking inspiration from photosynthesis, Professor Grätzel used green chlorophyll molecules to harvest light, and assembled the system in a way that made backward reactions slower than forward reactions for maximum efficiency. “Fundamental curiosity drove our research, but when we found results, we started to think about potential applications”, he said. #scientistsinSG bit.ly/gyssmichaelgraetzel

Reaction set up of PIC hydrogel [oligo(ethylene)glycol polyisocyanopeptide]... Paper: Responsive biomimetic networks from polyisocyanopeptide hydrogels... Nature Vol 493, pages 651–655 (31 January 2013) Camiel Steffanie [Student Intern]: After having purified the triethylene glycol functionalized isocyano-(D)-alanyl-(L)-alanine monomer using a silica column, it was time to do the nickel(II)-catalyzed polymerization. In these two different setups, I am studying the influence of temperature and stirring method on the polymer molecular weight. The resulting helical polymers will be later on functionalized with fluorescent dyes, just like I did with a previous batch (blue and yellow polymer solutions in flasks). #mechanobiology #chemistry #polymerchemistry #biopolymers

Above is periodic number 20, Calcium. Atomic mass: 40.08 g/mol Mass volume: 1.6 g.cm-3 at 20°C Melting point: 840 °C Boiling point: 1484 °C Isotopes: 10 Electronic configuration: [ Ar ] 4s2 The chemical element Calcium (Ca), atomic number 20, is the fifth element and the third most abundant metal in the earth’s crust. The metal is trimorphic, harder than sodium, but softer than aluminium. A well as beryllium and aluminium, and unlike the alkaline metals, it doesn’t cause skin-burns. It is less chemically reactive than alkaline metals and than the other alkaline-earth metals. Calcium ions solved in water form deposits in pipes and boilers and when the water is hard, that is, when it contains too much calcium or magnesium. This can be avoided with the water softeners. In the industry, metallic calcium is separated from the melted calcium chloride by electrolysis. This is obtained by treatment of carbonated minerals with chlorhydric acid, or like a sub product of the carbonates Solvay process. In contact with air, calcium develops an oxide and nitride coating, which protects it from further corrosion. It burns in the air at a high temperature to produce nitride. The commercially produced metal reacts easily with water and acids and it produces hydrogen which contains remarkable amounts of ammonia and hydrocarbides as impurities. Applications The metal is used in aluminium alloys for bearings, as a helper in the bismuth removal form lead, as well as in controlling graphitic carbon in melted iron. It is also used as a deoxidizer in the manufacture of many steels; as a reducing agent in the preparation of metals as chromium, thorium, zirconium and uranium, and as separating material for gaseous mixtures of nitrogen and argon.

This is shikimic acid! It is needed to make Tamiflu (oseltamivir), a common flu medication. Also in the picture is Chinese star anise, which is currently the source of the overwhelming majority of shikimic acid on the market. 🌱 Due to shortages of star anise and fear of pandemic flu, scientists are searching for alternative sources of shikimic acid. One possibility is genetically modified bacteria. 🧫 Shikimic acid is a natural product, which mean there are enzymes in the star anise plant that synthesize the shikimic acid all by themselves. Scientists can take the DNA that codes for those enzymes and put it in a type of bacteria. That bacteria would then be able to make shikimic acid for us! It would be the same exact molecule, just made through fermentation. 🦠 Despite the relation to oseltamivir (👉swipe to see it and compare), shikimic acid cannot be used to fight the flu. Oseltamivir sticks to a protein on the outside of the flu virus and prevents new baby flu viruses from bursting out of your cells to infect more cells. Shikimic acid doesn’t stick to this protein (which is why scientists go through so much trouble to make oseltamivir). If some wellness IG tells you to brew some star anise to cure the flu, know that it is 🐎💩. 😉 💕 Sources: (Ghosh et al 2012) https://doi.org/10.1016/j.biotechadv.2012.03.001 (Rawat et al 2013) https://link.springer.com/article/10.1007/s00253-013-4840-y
