The article considers how colour blindness proved no impediment to the discovery of new atomic elements, such as indium, through spectroscopy. It discusses that the English chemist is John Dalton (1766-1844), chiefly known in optics for his description of his own colour deficiency, the first person to describe the condition; and mentions that he postulated that each element comprised atoms of unique size and mass and assumed that elements combined as compounds in fixed proportions.

The article reports on the arsenicin A as the first natural product to be comprised of multiple arsenic atoms. It shows the development of a new arsenic drug through synthesizing arsenicin A. It mentions that the development of the drug began by the conversion of methylenebis into a linear tetraarsine derivative. Moreover, the teraarsine was sewed up to the adamantane-type structure by the replacement of phenyl groups with iodine, hydrolysis and dehydration.

The article discusses a study led by researcher Chongwu Zhouq, published in a 2015 issue of the periodical "Advanced Materials" related to development of atomically thin black arsenic-phosphorous semiconductors by heating arsenic and phosphorus compounds in the presence of a mineralizing agent.

The article offers information on a study in which apple juice samples are analyzed by Ion Chromatography (IC)-Inductively coupled plasma mass spectrometry (ICP-MS) to determine the concentration of six arsenic species. It informs that a Dionex ICS-5000 ion chromatogram is used for chromatographic separation. According to the findings of the study, combination of IC with ICP-MS can be used as powerful tool for the detection of low concentrations of arsenic species in fruit juices.

The article reports the benefit which the transport protein Aquaglyceroporin-9 (AQP-9) gives in order to fight arsenic compounds. AQP-9 is a protein which helps fight toxins caused by arsenic to the body, by protecting the liver. Jennifer M. Carbrey of Duke University states that after conducting an experiment on mice, she finds that arsenic accumulates to the liver and heart in the absence of AQP-9. Moreover, Carbrey recommends drinking clean water to avoid arsenic toxins.

Information about the topics discussed during a meeting in China on April 14, 2009 is presented. The meeting tackled the arsenic pollution accidents in the country since early 2008. The event outlined the report "Standards for Drinking Water Quality" released by the Ministry of Health and the National Standardization Management Committee claiming that arsenic concentration should be reduced to 0.01-milligram per liter in drinking water nationwide.

The article offers news briefs related to spectroscopy in the U.S. in 2009. Researchers at University of Massachusetts in Amherst, Massachusetts have developed the first accurate test for arsenic compounds in soil. Scientists from Lawrence Livermore National Laboratory in Livermore, California have converted the highest frequency sound waves into electricity by reversing the process that converts electrical signals to sound.

The article discusses the study on compounds with three arsenic atoms. Andrey V. Protchenko, Michael F. Lappert, and co-workers of the University of Sussex in England have made compounds with three arsenic atoms. Chemistry professor Bryan Eichhorn of the University of Maryland depicts that the interesting thing about the compound is the three different formal oxidation states of the arsenic atoms all in the same unit.

The article focuses on arsenic, its therapeutic benefits, toxicity and carcinogenicity. For a thousand yeas, aresenic functioned as a therapeutic agent and poison. During the 19th century, arsenides and arsenic salts were used to treat ulcers and cancer. But in 1878, it was discovered that it lowers white blood cell counts in normal individuals. Despite advancements involving arsenic, concerns were raised about its toxicity. Among its adverse effects are carcinogenicity and skin cancer.

The article reports that a group of researchers at the University of Graz in Austria has isolated arsenic-containing oil from capelin, a North Atlantic fish in the smelt family. The researchers identified three different arsenic-containing compounds, two dimethylarsinoyl alkanes and a dimethylarsinoyl alkene. The study provides new information about the molecular forms that arsenic adopts in capelin and other fish.

The article reports on the non-uniform clumping of arsenic dopant atoms in silicon semiconductors. According to a conducted investigation on atomic components of silicon samples using three-dimensional maps with unprecedented resolution, the silicon device fabrication methods show a non-uniform dopant distribution which could cause more problems on future generation of devices. It was believed that the shortcoming in dopant dispersion could affect the performance of microelectronic devices.

Presents a letter to the editor in response to the article "Arsenic in Rice," published in the August 8, 2005 issue of the journal "Chemical & Engineering News."

Focuses on the ways to remove arsenic from water supplies.
