According to new NASA research, a wider range of asteroids were capable of creating the kind of amino acids used by life on Earth. Researchers at NASA's Goddard Space Flight Center reported in 2009 that they discovered an excess of the left-handed form of the amino acid isovaline in samples of meteorites that came from carbon-rich asteroids.  NASA said that this discovery suggests that left-handed life got its start in space, where conditions in asteroids favored the creation of...

Developing new drugs is a highly costly and time-consuming process. Of 20 candidates, 19 are normally rejected because they don't work or have unwanted side effects. Now a research team led by Professor Lars Baltzer at Uppsala University has produced a tiny molecular "binder" that has the potential to change this landscape radically. The study, published today in the prestigious journal Angewandte Chemie, presents the concept of a tiny polypeptide consisting of 42 amino acids to which...

Acid Rain
2013-04-01 10:21:17

Acid rain is any form of precipitation that is unusually acidic, meaning that is possesses high levels of hydrogen ions. It can have harmful effects on aquatic animals, plants, and infrastructure. Acid rain is caused by emissions of sulfur dioxide and nitrogen oxide, which react with the water molecules within the atmosphere to produce acids. Nitrogen oxides can be produced naturally by lightening strikes. Sulfur dioxide can be produced naturally by volcanic eruptions. The chemicals that are...

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...
