WASHINGTON — A draft plan to conserve habitat for endangered and threatened fishes in the California Bay-Delta while continuing to divert water for agricultural and personal use in central and southern California has critical missing components, including clearly defined goals and a scientific analysis of the proposed project's potential impacts on delta species, says a new report from the National Research Council. In addition, the scientific information in the plan is fragmented and presented in an unconnected manner, making its meaning difficult to understand.

COLLEGE STATION, May 4, 2011 – The so-called "bad cholesterol" – low-density lipoprotein commonly called LDL – may not be so bad after all, shows a Texas A&M University study that casts new light on the cholesterol debate, particularly among adults who exercise.
Researchers at North Carolina State University have found a specific gene in corn that appears to be associated with resistance to three important plant leaf diseases.
In a paper published this week in Proceedings of the National Academy of Sciences, NC State plant pathologists and crop scientists pinpoint the gene – glutathione S-transferase – that seems to confer resistance to Southern leaf blight, gray leaf spot and Northern leaf blight, a trio of diseases that cripple corn plants worldwide.
A new study identifies the mutation that underlies a rare, inherited accelerated-aging disease and provides key insight into normal human aging. The research, published by Cell Press online May 5 in the American Journal of Human Genetics, highlights the importance of a cellular structure called the "nuclear envelope" in the process of aging.
DALLAS, May 5, 2011 – A UT Southwestern Medical Center researcher has identified the most comprehensive measurement to date of estrogen's effect on breast cancer cells, showing for the first time how immediate and extensive the effect is.
The findings, published online today and in the May 13 print edition of the journal Cell, could lead to a new set of therapeutic applications and provide a model for understanding rapid signal-dependent transcription in other biological systems.
CHAPEL HILL, N.C. – Researchers at the University of North Carolina at Chapel Hill School of Medicine, after isolating normal stem cells that form the developing placenta, have given them the same properties of stem cells associated with an aggressive type of breast cancer.
The scientific first opens the door for developing novel targeted therapies aimed at triple negative breast cancer. Known also as TNBC, this is a highly recurrent tumor that spreads aggressively beyond its original site in the breast and carries a poor prognosis for patients who have it.
An international team of researchers co-led by a University of Minnesota scientist has sequenced the genomes of two fungal pathogens -- one that threatens global wheat supplies and another that limits production of a tree crop valued as a future source for biofuel.
A Swedish research team partly consisting of researchers from Uppsala University followed a group of prostate cancer patients in the Nordic region for 15 years. The study found, among other things, that surgery reduces the risk that men with prostate cancer (even those with low-risk tumours) will die within 15 years. The results were published today in the New England Journal of Medicine.
The recent nuclear accident in Fukushima Daiichi in Japan has brought the nuclear debate to the forefront of controversy. While Japan is trying to avert further disaster, many nations are reconsidering the future of nuclear power in their regions. A study by Behnam Taebi from the Delft University of Technology, published online in the Springer journal Philosophy & Technology, reflects on the various possible nuclear power production methods from an ethical perspective: If we intend to continue with nuclear power production, which technology is most morally desirable?
Scientists have discovered why some people may be protected from harmful parasitic worms naturally while others cannot in what could lead to new therapies for up to one billion people worldwide.
Parasitic worms are a major cause of mortality and morbidity affecting up to a billion people, particularly in the Third World, as well as domestic pets and livestock across the globe.
Now, University of Manchester researchers have, for the first time, identified a key component of mucus found in the guts of humans and animals that is toxic to worms.
An international team of researchers studied the parareptiles, a diverse group of bizarre-looking terrestrial vertebrates which varied in shape and size. Some were small, slender, agile and lizard-like creatures, while others attained the size of rhinos; many had knobbly ornaments, fringes, and bony spikes on their skulls.
The researchers found that, surprisingly, parareptiles were not hit much harder by the end-Permian extinction than at any other point in their 90 million-year history.
Familiar blueberries and their lesser-known wild relatives are safeguarded by U.S. Department of Agriculture (USDA) scientists and curators at America's official blueberry genebank. The plants, collected from throughout the United States and more than two dozen foreign countries, are growing at the USDA Agricultural Research Service National Clonal Germplasm Repository in Corvallis, Ore.
Montreal May 5, 2011 – Children whose mother or father is affected by bipolar disorder may need to keep their stress levels in check. A new international study, led by Concordia University, suggests the stress hormone cortisol is a key player in the mood disorder. The findings published in Psychological Medicine, are the first to show that cortisol is elevated more readily in these children in response to the stressors of normal everyday life.
French researchers have reported the strongest proof yet that evidence of 'circulating tumor cells' found in samples of a patient's blood is strongly linked to poor outcomes such as a short time to disease progression.
At the IMPAKT Breast Cancer Conference in Brussels, Dr François-Clement Bidard and colleagues from Institut Curie in Paris say their new findings set the scene for interventional trials designed to see if improved outcomes can be achieved by modifying treatment based on circulating tumor cell counts.
