With the demand for organically produced food increasing, and therefore the marketing and business opportunities for exaggerated benefits, scientists are reporting new evidence that organically grown onions, carrots, and potatoes generally do not have higher levels of healthful antioxidants and related substances than vegetables grown with traditional fertilizers and pesticides. Their study appears the Journal of Agricultural and Food Chemistry.

Montreal, November 3, 2010 – Stress may be more hazardous to our mental health than previously believed, according to new research from Concordia University. A series of studies from the institution have found there may be a link between the recent rise in depression rates and the increase of daily stress.
BETHESDA, MD – October 15, 2010 – Thousands of the world's top scientists and clinicians in the human genetics field will convene to present their latest research findings at the American Society of Human Genetics (ASHG) 60th Annual Meeting, on November 2-6, 2010, in Washington, D.C.
WEST LAFAYETTE, Ind. - Physical defects in plants can be predicted based on chromosome imbalances, a finding that may shed light on how the addition or deletion of genes and the organization of the genome affects organisms, according to a study involving a Purdue University researcher.
In a finding that upends decades of scientific theory on reptile reproduction, researchers at North Carolina State University have discovered that female boa constrictors can squeeze out babies without mating.
More strikingly, the finding shows that the babies produced from this asexual reproduction have attributes previously believed to be impossible.
Athens, Ga. – New University of Georgia research suggests moving threatened animals to protected habitats may not always be an effective conservation technique if the breeding patterns of the species are influenced by a social hierarchy.
The amount of water flowing in streams and rivers has been significantly altered in nearly 90 percent of waters that were assessed in a new nationwide USGS study. Flow alterations are a primary contributor to degraded river ecosystems and loss of native species.
Photosynthesis is arguably the most impressive feat of nature, where plants harvest light energy and convert it into the building blocks of life at fantastically high efficiency. Indeed modern civilization became possible only with the cultivation of plants for food, shelter and clothing.
At least six psyllid species have been found in the citrus-growing areas of the Rio Grande Valley of Texas, according to a U.S. Department of Agriculture (USDA) scientist who is working to control the spread of the psyllid-transmitted citrus greening disease.
A new study by Greek researchers suggests that the biologic drug bortezomib (Velcade), a proteasome inhibitor used to treat multiple myeloma (bone marrow cancer), may represent a promising treatment for rheumatoid arthritis (RA). In this study, bortezomib displayed favorable effects in an animal model of inflammatory arthritis that mimics RA, in reducing disease severity and inflammation, and promoting bone healing. Full findings of this study are published in the November issue of Arthritis & Rheumatism, a journal of the American College of Rheumatology (ACR).
It is hard to believe that they belong to the same species: The large, long-lived queen bee is busy producing offspring throughout her lifetime. The much smaller worker bees, on the other hand, gather food, take care of the beehive, look after and feed the brood – but they are infertile.
When a team of European researchers sought to discover how a class of antiviral drugs worked, they looked in an unlikely place: the sugar dish. A new research report appearing in the Journal of Leukocyte Biology (http://www.jleukbio.org) suggests that a purified and modified form of a simple sugar chain may stop fast-acting and deadly viruses, such as Ebola, Lassa, or Marburg viruses, in their tracks.
Stock markets react to crisis in a similar way to plants and the human body, according to a major new study that may help to predict future financial down-turns.
An extensive analysis of biological and financial data suggests that systems under stress exhibit similar symptoms, whether they be polluted forests, cancer patients or the FTSE 100.
SAN DIEGO, CA (November 3, 2010)—Removal of the prostate gland often eradicates early-stage cancer. But patients whose cancer has spread may need to follow up with what is known as salvage radiation therapy. Researchers at Fox Chase have now determined a better way to monitor outcomes after this procedure.
