At some point in elementary school you were shown that opposite charges attract and like charges repel. This is a universal scientific truth – except when it isn’t. A research team led by Berkeley Lab chemist Richard Saykally and theorist David Prendergast, working at the Advanced Light Source (ALS), has shown that, when hydrated in water, positively charged ions (cations) can actually pair up with one another. “Through a combination of X-ray spectroscopy, liquid microjets and first...

Screening method created to expedite the development of new drugs in the fight against tropical diseases such as malaria and African sleeping sickness A novel tool exploits baker's yeast to expedite the development of new drugs to fight multiple tropical diseases, including malaria, schistosomiasis, and African sleeping sickness. The unique screening method uses yeasts which have been genetically engineered to express parasite and human proteins to identify chemical compounds that target...

Chemicals found at low levels at all sites tested URI researcher: 'Emerging contaminants of concern' detected throughout Narragansett Bay watershed A group of hazardous chemical compounds that are common in industrial processes and personal care products but which are not typically monitored by the Environmental Protection Agency have been detected throughout the Narragansett Bay watershed, according to a URI researcher. Rainer Lohmann, associate professor of chemical oceanography,...

Research performed in Guy Bertrand's lab offers vast family of new catalysts for use in drug discovery, biotechnology Chemists at the University of California, Riverside have accomplished in the lab what until now was considered impossible: transform a family of compounds which are acids into bases. As our chemistry lab sessions have taught us, acids are substances that taste sour and react with metals and bases (bases are the chemical opposite of acids). For example, compounds of the element...

Researchers exploring human metabolism at the University of California, San Francisco (UCSF) have uncovered a handful of chemical compounds that regulate fat storage in worms, offering a new tool for understanding obesity and finding future treatments for diseases associated with obesity. As described in a paper published this month in the journal Nature Chemical Biology, the UCSF team took armies of microscopic worms called C.elegans and exposed them to thousands of different chemical...

As part of a multicenter study, UT Southwestern Medical Center researchers have identified a series of chemical compounds that might serve as starting points for the identification of new classes of anti-malarial drugs. "Malaria remains one of the most globally significant infectious diseases that we face," said Dr. Margaret Phillips, professor of pharmacology at UT Southwestern and one of the senior authors of the study, which appeared in the May 20 issue of Nature. Malaria affects about 40...

Broadly speaking, ants have two different feeding strategies. A large proportion of all species are "carnivorous," meaning that they are generalist predators feeding on other small animals or scavenging on their remains. Some, however, are "herbivorous". This is not to say that they only eat plants; rather, the bulk of their diets consist of plant-derived matter. For example, some forage on sticky fluids produced by plants to attract ants, called extra-floral nectar; others feed on the...

In chemistry, salt is a general term used for ionic compounds composed of positively charged cations and negatively charged anions, so that the product is neutral and without a net charge. These ions can be inorganic (Cl-) as well as organic (CH3-COO-) and monoatomic (F-) as well as polyatomic ions (SO42-). Solutions of salts in water are called electrolytes. Electrolytes as well as molten salts conduct electricity. Zwitterions are salts that contain an anionic center and a cationic...
