Database shows effects of acid rain on microorganisms in Adirondack Lakes
Prior to the federal Clean Air Act, unhindered industrial emissions were released into the air throughout the Midwestern and Eastern United States for decades. Many of those harmful chemicals came right back down to earth in the form of acid rain, a chemical concoction that includes nitric and sulfuric acid. view more (2008-06-24)
Health: Improving the recognition of brain tumours
Researchers at the Institute of Nuclear Chemistry in Jülich have developed a short-lived, radioactive amino acid that delivers much more precise information on brain tumours and their structure than was possible in the past. By combining positron emission tomography (PET), a process that visualises the spread of radioactive substances in the... view more... (2005-05-04)
Vitamin B12 function may be diminished by excessive folate
In a study of adults aged 20 and over, researchers at Tufts University showed that homocysteine and methylmalonic acid are at much higher levels in individuals who have a combination of vitamin B12 deficiency and high blood folate levels than in individuals who are also vitamin B12 deficient but have normal folate levels. view more (2007-12-19)
Acid suppression medication linked with increased risk of hip fracture
Use of the drugs proton pump inhibitors (PPIs) for the treatment of acid-related diseases such as gastro esophageal reflux disease (GERD) is associated with a greater risk of hip fracture. view more (2006-12-27)
How corals adapt to day and night
Researchers have uncovered a gene in corals that responds to day/night cycles, which provides some tantalizing clues into how symbiotic corals work together with their plankton partners. view more (2008-09-15)
Surprisingly, Chemists Find, Some Solvents Can Alter Chemical Bonds
New University at Buffalo research demonstrates that some solvents can significantly enhance certain acid-base interactions and strengthen the bonding interaction between two molecules when one is electron-deficient and one is electron-rich. view more (2007-07-25)
Trans fats hinder multiple steps in blood flow regulation pathways
Partially hydrogenated vegetable oils in processed foods contain trans fatty acids that interfere with the regulation of blood flow. A new report reveals a new way in which these "trans fats" gum up the cellular machinery that keeps blood moving through arteries and veins. view more (2009-06-17)

Press release from Nature and the Nature Research Journals dated 7 September
NATURE (http://www.nature.com/nature) [1] Uric acid signals danger DOI: 10.1038/nature01991 (http://dx.doi.org/10.1038/nature01991) Uric acid may signal the immune system to warn it of impending danger, according to a paper published online by Nature this week. The research provides a molecular link between cell injury and immunity, and may have... view more... (2003-09-08)
Potassium limitation, ammonium toxicity and amino acid excretion in yeast
As a single-celled eukaryote organism, the yeast strain S. cerevisiae has some limitations in terms of how it can be used as a model for more complex multicellular eukaryotes. view more (2006-10-17)
Carnegie Mellon scientists create PNA molecule with potential to build nanodevices
For the first time, a team of investigators at Carnegie Mellon University has shown that the binding of metal ions can mediate the formation of peptide nucleic acid (PNA) duplexes from single strands of PNA that are only partly complementary. view more (2005-10-04)
New UNC experiments show very weak chlorine solutions can kill noroviruses
Chlorine solutions much weaker than previously believed can still be used to kill more than 99 percent of noroviruses, the chief cause of outbreaks of gastrointestinal illness around the world, a new University of North Carolina at Chapel Hill study concludes. view more (2005-12-20)
Hot volcanic eruptions could lead to a cooler Earth
Volcanic eruptions may be an agent of rapid and long-term climate change, according to new research by British scientists. view more (2005-06-13)
New EU regulations lead to increased risk of cannibalism in hens
A hen has a hard time surviving on feed containing 100% environmentally certified ingredients, as the EU proposes to require as of the summer of 2005. Hens would not take in enough of the vital amino acid metionin, which would increase the risk of feather pecking and cannibalism, according to a new study by the Swedish University of Agricultural... view more...

Food additive may one day help control blood lipids and reduce disease risk
Scientists at Washington University School of Medicine in St. Louis have identified a substance in the liver that helps process fat and glucose. That substance is a component of the common food additive lecithin, and researchers speculate it may one day be possible to use lecithin products to control blood lipids and reduce risk for diabetes,... view more...

arrow researcher finds natural hydrogel helps heal spinal cord
Research led by a scientist at the Barrow Neurological Institute at St. Joseph's Hospital and Medical Center has shown injecting biomaterial gel into a spinal cord injury site provides significantly improved healing. view more (2009-09-17)
Cornell researchers identify natural herbicide that controls weeds around some common lawn grasses
Certain varieties of common fescue lawn grass come equipped with their own natural broad-spectrum herbicide that inhibits the growth of weeds and other plants around them. view more (2007-11-09)
Uric acid and spinal cord injury treatment
Uric acid is commonly associated with the excruciatingly painful joint disease known as gout, but it can also play a crucial role in the treatment of spinal cord injury and other central nervous system disorders, such as stroke, multiple sclerosis and Parkinson's disease, according to Rutgers' Bonnie Firestein. view more (2007-01-04)
Supplementing babies' formula with DHA boosts cognitive development
Research has shown that children who were breast fed as infants have superior cognitive skills compared to those fed infant formula, and it's thought that this is due to an essential fatty acid in breast milk called docosahexaenoic acid (DHA). view more (2009-09-15)
