The degradation of proteins and other macromolecules in cells is vital to survival. Disruption of this process can result in serious disease. The research group of Professor Thomas Jentsch (Leibniz Institute for Molecular Pharmacology, FMP/ Max Delbrck Center for Molecular Medicine, MDC, Berlin-Buch) has now succeeded in identifying an essential cellular process necessary for the transport and degradation of macromolecules in endosomes and lysosomes, respectively. In two studies published in...

Using a chemical trick that allows them to change the acidity of a solution almost instantly, a team at the National Institute of Standards and Technology (NIST) has demonstrated a simple and effective technique for quantifying how the stability of nanoparticle solutions change when the acidity of their environment suddenly changes*. The measurement method and the problem studied are part of a broader effort at NIST to understand the environmental, health and safety implications of...

Scientists at the University of Pittsburgh School of Medicine went on a molecular fishing trip and netted a catch of new mediators that not only can explain how omega-3 fatty acids reduce inflammation, but also hint at novel treatments for a host of diseases linked to inflammatory processes. Their findings were published May 2 in the online version of Nature Chemical Biology. There is strong evidence that eating foods rich in omega-3 fatty acids, such as some fish, plant-derived oils and...

Scientists are reporting discovery of what may be the "ancestral Eve" crystal that billions of years ago gave life on Earth its curious and exclusive preference for so-called left-handed amino acids. Those building blocks of proteins come in two forms "” left- and right-handed "” that mirror each other like a pair of hands. Their study, which may help resolve one of the most perplexing mysteries about the origin of life, is in ACS' Crystal Growth & Design, a bi-monthly...

Using genetic sleight of hand, researcher Xinyao Liu and professor Roy Curtiss at Arizona State University's Biodesign Institute have coaxed photosynthetic microbes to secrete oil"”bypassing energy and cost barriers that have hampered green biofuel production. Their results appear in this week's advanced online issue of the Proceedings of the National Academy of Sciences or PNAS. The challenges of developing a renewable biofuel source that is competitive with the current scalability and...

Graphene"”carbon formed into sheets a single atom thick"”now appears to be a promising base material for capturing hydrogen, according to recent research* at the National Institute of Standards and Technology (NIST) and the University of Pennsylvania. The findings suggest stacks of graphene layers could potentially store hydrogen safely for use in fuel cells and other applications. Graphene has become something of a celebrity material in recent years due to its conductive, thermal...

Chemicals that helped solve a global environmental crisis in the 1990s "” the hole in Earth's protective ozone layer "” may be making another problem "” acid rain "” worse, scientists are reporting. Their study on the chemicals that replaced the ozone-destroying chlorofluorocarbons (CFCs) once used in aerosol spray cans, air conditioners, refrigerators, and other products, appears in ACS' Journal of Physical Chemistry A, a weekly publication. Jeffrey Gaffney, Carrie J....

DAVIS, Calif., Feb. 23 /PRNewswire/ -- A battle has developed in the coffee trade between industry leader Folgers® (owned by The J.M. Smucker® Company), and an upstart, Puroast® Low Acid Coffee. The lines are drawn around the estimated 35 million Americans who have stomach acid problems like acid reflux, heartburn, et al., who have had to eliminate their morning caffeine boost as they can't drink regular coffee because its high acid...

The increasing acidity of the world's oceans - and that acidity's growing threat to marine species - are definitive proof that the atmospheric carbon dioxide that is causing climate change is also negatively affecting the marine environment, says world-renowned Antarctic marine biologist Jim McClintock, Ph.D., professor in the University of Alabama at Birmingham (UAB) Department of Biology. "The oceans are a sink for the carbon dioxide that is released into the atmosphere," says McClintock,...

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...
