This article talks about a study that was done by Georgia State University which shows that chemical compounds could prevent the replication of the Ebola virus. In the study, a library of 200,000 molecule compounds were screened by researchers to find which ones could inhibit the multiplication of Ebola virus. Of those, there were 56 hits that inhibited the Ebola virus by 70% while having less than 20% chance of being toxic to cells. This study will be useful to future treatments of the Ebola virus.
Interesting article concerning how the US Environmental Protection Agency (EPA) is dealing with public demand for stricter regulations on chemicals in production since 1940. The public is concerned about long term exposure to chemical compounds found in the everyday products we use especially perfluoroalkyl and polyfluoroalkyl compounds (PFAS). These chemicals are found in products like pots and pans, shampoo, makeup, but also have contaminated the water supply and wildlife.
There's growing evidence that long-term exposure to the perfluoroalkyl and polyfluoroalkyl compounds can be dangerous.
Studies have found “probable links” between exposure to PFAS and increased incidents of excessive cholesterol levels, thyroid disease, cancer, and pregnancy problems. Many states have already set stricter standards than those currently required by the EPA – New York may impose the toughest to date.
This article reports on an interesting discovery by scientists regarding helium. Although it is classified as a noble gas, researchers were able to get helium and sodium to form a stable compound by compressing them under extreme pressures. They aren't completely sure how they formed a stable compound, but they know that they are not sharing an electron, the way compounds are formed traditionally. They also predict that helium can make other compounds with magnesium, fluoride and calcium fluoride.
This website is demonstrating major advancements in the world of glues and adhesives. Molecular glue binds two objects together by chemically bonding atoms of two different substances thus creating a compound. This process makes separation virtually impossible. It will, however, set you back several thousand dollars.
The article talks about how the element of helium, a noble gas, could make compounds under pressure. The element of helium doesn't form a chemical bond but instead it can insert itself in the middle of a compound to keep the compound stable. This was proven in a 2017 study where helium and sodium made a stable compound under pressure. Helium is like the nanny when chemical compounds are under pressure.
For a few minutes in this episode of Bill Nye the Science Guy, he explains molecules in general as “words” that are made up of atoms, which would be “letters”. He then uses H2O as an example.
He mentions that when the atoms come together, they stick---two parts Hydrogen, one part Oxygen. To show that these two gases bond together to create H2O, he uses this machine that passes electricity through the water, separating it into Hydrogen and Oxygen. They are both “pure”, since each gas is made up of only one element.
Finally, he explains how experiments like the one he demonstrated led to scientists discovering the chemical composition of water, as well as many other compounds.
This article/video talks about a research project using crowdsourcing to improve health research by involving the scientific community. Datas of the reaction of chemical compounds were shared with scientists globally and they analyzed it along with the findings each participating group described. As a conclusion, the findings had allowed an improved prediction on effects of chemical compounds on individuals and highly suggested crowdsourcing as a positive effect on science researchs.
Scientists recently found the structure of a Chinese fir tree could counter pancreatic cancer when combined with an existing cancer drug. Nicknamed "Compound 30", the new compound they've created bonds with SHP2, an enzyme associated with many different types of cancer other scientists have been trying to counter. What makes this successful and more stable to keep it under control is that this bond is a covalent one, making it more secure compared to other attempts.
This article talks about a previously unknown class of metal-organic compound that was discovered by scientists who were analyzing meteorites. This new compound has never been recorded in chemical databases before and international teams say that this new discovery could shed some light of the evolution of organic compounds in meteorites.
This is an interesting article regarding states in the US, specifically Philadelphia. Toxic chemicals have gotten into these environments decades back, and have not gone regardless of the banned use of them (specifically perfluoroalkyl and polyfluoroalkyl substances, known collectively as PFAS). PFAS makes a big impact on one's body, from cancer to decreased fertility. The EPA (Environmental Protection Agency) has started to take this seriously as it has been found in water, and even non-stick pans. However, the EPA has received lots of criticism for only giving a tiny outline, with no fixed dates set for the environmental treatment planned to remove PFAS and other toxic chemicals. It will be interesting to see how long it will take for the EPA to actually implement their plan and succeed.
This article talks about how you can't just randomly create a new compound and use it freely. A company making the compound "GenX" failed to share with EPA the potentially hazardous parts of the chemical compound and are now getting sued as GenX made it's way into the residential water system without antone even knowing what the compound does yet.
The article is talking about how a chemical maker company in North Carolina failed to notify the US Environmental Protection Agency that they discovered a chemical which contaminated water wells and properties. All companies are required to notify the agency if there is a potential threat to humans or the environment. This was not the first time this company failed to comply with agreements that were already set.
People like sweetness, and so do the ancient Romans. However, on top of sugar and honey that we typically use, the Romans used lead (II) acetate, a deadly poison, to sweeten and preserve their food and wine.
Now, the Romans were not aware that the compound was in their food. Instead, it was leaked into defrutum and sapa, syrup made from grape juice, as they were boiled in lead or lead-lined pots. Lead (II) acetate is very sweet in taste, though people who consumed it is at high risk of brain and kidney damage. Some historians even argued that this was why there were less and less children born within the Roman nobility, as they are suspected to have consumed it in high quantity and thus made sterile from lead poisoning. Nevertheless, one lesson was to be learned for their descendants: it was important, perhaps even life-saving, to understand the ingredients that are in your food and surroundings and how they affect you.
This article discusses the first ever bonding of the elements iron and bismuth. These two elements normally do not bond due their chemical properties and electron configurations. However, scientists utilized great pressure and heat to combine these two elements and made a novel compound, FeBi2. The pressure that is required is equivalent to that of the core of the planet Mars.
