Newly discovered reactions from an old drug may lead to new antibiotics
A mineral found at health food stores could be the key to developing a new line of antibiotics for bacteria that commonly cause diarrhea, tooth decay and, in some severe cases, death. view more (2009-06-02)
Wildlife researchers identify impacts of contamination in amphibians
Bill Hopkins, fisheries and wildlife associate professor in Virginia Tech's College of Natural Resources, and colleagues doing research at the Savannah River Ecology Laboratory and in the field, have demonstrated that amphibians are exposed to contaminants through maternal transfer, as has been proven for other vertebrates. view more (2006-02-22)
The Right Food Can Improve Fertility
Roasted red peppers, mini crab cakes and Brazil nuts can all help to increase fertility. They will all feature in a special Fertility Buffet, laid on by Dr Margaret Rayman, Director of the MSc Course in Nutritional Medicine at the University of Surrey, on 3 July 2003. A good, balanced diet rich in fruit and vegetables (at least five portions a... view more... (2003-06-30)
No Benefits From Vitamin Supplements In Protection Against Gastro-Intestinal Cancer (pp 1193, 1219)
A systematic review and meta-analysis (pooled analysis) of previously published randomised trials in this week's issue of THE LANCET provides strong evidence that antioxidant supplements (such as vitamin supplements) are not effective in protecting against gastro-intestinal cancer. Some combinations of supplements may slightly increase... view more... (2004-09-29)
Higher levels of pollutants found in fish caught near a coal-fired power plant
Emissions from coal-fired power plants may be an important source of water pollution and fish contamination. view more (2007-11-07)
Healthy rocks and wildlife farming
The relationship between rocks and our health, and new methods for farming and countryside management to both encourage wildlife and make a profit, are just two of the exciting research projects highlighted in the latest issue of Planet Earth, the quarterly journal of the Natural Environment Research Council (NERC). The rock diet Rocks are a vital... view more... (2002-10-23)
Use of some antioxidant supplements may increase mortality risk
Contradicting claims of disease prevention, an analysis of previous studies indicates that the antioxidant supplements beta carotene, vitamin A, and vitamin E may increase the risk of death. view more (2007-02-28)
First Genome Comparison of Plankton Species Yields Surprises Underlying Key Ocean Processes
An international team of scientists led by Scripps Institution of Oceanography at UC San Diego and the Department of Energy's (DOE) Joint Genome Institute has peered into the genetic makeup of two species of phytoplankton, the tiny plants key in global photosynthesis and carbon cycling, and come away with surprising results about evolutionary... view more...

What Have Bats, Computer Science And Selenium Got In Common?
Bats, Computer Science and Selenium are three of the research areas to be covered by past and present fellows of the Daphne Jackson Trust in a symposium to celebrate its 10th Anniversary on Monday 21st January at the University of Surrey. There will be five presentations from Daphne Jackson Fellows who will talk about their research and the... view more... (2002-01-15)
Fortified Milk Reduces Morbidity in Preschool Children
Consumption of milk fortified with specific micronutrients-zinc, iron, selenium, copper, vitamin A, vitamin C and vitamin E-significantly reduces diarrhea and acute lower respiratory illness among children in developing countries, according to researchers from the Johns Hopkins Bloomberg School of Public Health and the Center for Micronutrient... view more...

'Strained' quantum dots show new optical properties
Quantum dots, tiny luminescent particles made of semiconductors, hold promise for detecting and treating cancer earlier. However, if doctors were to use them in humans, quantum dots could have limitations related to their size and possible toxicity. view more (2008-12-08)
Natural compounds, chemotherapeutic drugs may become partners in cancer therapy
Research in the Linus Pauling Institute at Oregon State University suggests that some natural food compounds, which previously have been studied for their ability to prevent cancer, may be able to play a more significant role in treating it - working side-by-side with the conventional drugs that are now used in chemotherapy. view more (2009-08-31)
Scientists from the UAB and ICMAB achieve unprecedented control of formation of nanostructures
A team of researchers from the Universitat Autònoma de Barcelona, together with researchers from ICMAB (CSIC) and other Russian and Ukrainian scientists, have discovered an unprecedented method for accurately controlling the formation of nanometric structures made of semiconducting material in the form of islands, using promising... view more...

New Nanocrystals Show Potential for Cheap Lasers, New Lighting
For more than a decade, scientists have been frustrated in their attempts to create continuously emitting light sources from individual molecules because of an optical quirk called "blinking," but now scientists at the University of Rochester have uncovered the basic physics behind the phenomenon, and along with researchers at the... view more...

British breadmaking wheats are selenium deficient
Research just published has revealed selenium (Se) levels in British bread-making wheats ten to fifty fold lower than in their American or Canadian counterparts. Bread made from such wheat will fail to help consumers meet the Se intake levels recommended for human health. Ironically, reduced pollution may be partly to blame, "A general deficiency... view more... (2002-08-01)
Helping plants avoid the price of war
The U.S and allies are under growing pressure to present a clear plan for the clean up of the effects of war in both Afghanistan and Iraq. New research, to be presented today at the Society for Experimental Biology's annual conference, reveals how plants could form a key aspect of future plans. By using plants that avoid the radioactive hangover... view more... (2003-04-03)
Professor sheds light on DNA mechanisms
By manipulating individual atoms in DNA and forming unique molecules, a Georgia State University researcher hopes to open new avenues in research towards better understanding the mechanisms of DNA replication and transcription, and perhaps leading to new treatments for diseases. view more (2009-07-20)
How do the choline compounds change when apoptosis occurs?
Apoptosis is a programmed, active, highly selective mechanism of cell death. Abnormal regulation of apoptosis can lead to disorders such as cancer. The field of apoptosis research has undergone an explosion of new knowledge over the past decade. view more (2008-09-24)
New fertilizer SRM can help control heavy metal content
A new reference material developed by the National Institute of Standards and Technology (NIST) can help the agriculture industry and state regulators monitor the concentrations of several potentially hazardous heavy metal contaminants in fertilizers. view more (2006-10-13)
Protein suppresses prostate cancer, enhances effects of vitamin E
Researchers have identified a protein that disrupts an important signaling pathway in prostate cancer cells and suppresses growth of the cancer. view more (2005-11-01)
