All animals face the challenge of deciding which chemicals in the environment are useful and which are harmful. A new study greatly improves our understanding of how animals sense an important class of potentially harmful chemicals: weak acids. The study appears online on May 16 in the Journal of General Physiology (www.jgp.org). Weak acids like acetic acid (vinegar) and propionic acid (present in fermented foods like Swiss cheese) are shunned by many animals, and with good reason. Many...

'Lost' samples from famous origin of life researcher could send the search for Earth's first life in a new direction Stanley Miller gained fame with his 1953 experiment showing the synthesis of organic compounds thought to be important in setting the origin of life in motion. Five years later, he produced samples from a similar experiment, shelved them and, as far as friends and colleagues know, never returned to them in his lifetime. More 50 years later, Jeffrey Bada, Miller's former student...

Color change confirms a new way to harvest energy from sunlight Professor Richard Watt and his chemistry students suspected that a common protein could potentially react with sunlight and harvest its energy "“ similar to what chlorophyll does during photosynthesis. The story of how they proved it sounds as colorful as the legend of the leprechaun who hid his pot of gold at the end of the rainbow. They started with citric acid from oranges and mixed it with the protein. Next they...

Scientists have found more evidence that life on Earth may have been seeded by material from asteroids or comets. Prior research has shown how amino acids could form elsewhere in the cosmos. These molecules can form in two versions, but life on Earth exclusively uses just one of them. New research shows how conditions around a far-flung star could favor the formation of one type over another. Amino acids are corkscrew-shaped molecules that can form twisted to the left or right, and...

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...
