Mass flowering crops enhance pollinator densities at a landscape scale
...ittle value to pollinators. However, in an article soon to appear in Ecology Letters, C. Westphal, I. Steffan-Dewenter and T. Tscharntke show that the densities of bumblebees, a key group of pollinators in European agroecosystems, did not appear to be related to the amount of semi-natural habitats, as pre...NIH told regular and moderate exposure to sunlight is the key to preventing chronic disease
.... Rewriting the recommended daily requirements as soon as possible should be a top priority. "Taking diet supplements or drinking foods that have been fortified with Vitamin D is too often inadequate since a patient would have to drink the equivalent of 10 days of fortified milk or orange juice every d...New findings in yeast may reveal why growing older is the greatest carcinogen in humans
...keep track of each new generation. The buds, which soon grew into small colonies, were genetically manipulated to turn bright red or dark brown if they started showing signs of genetic instability. About three-quarters of the way through the life of each mother cell, colored colonies appeared, signaling t...Using GPR to estimate tree root biomass
...the integrity of roads and bridges. FS researchers soon recognized the potential for using the technology in forest-based research. Measuring the belowground growth of trees is essential to understanding forest productivity and carbon allocation. Estimating the biomass of tree roots traditionally involve...Researchers measure effects of flow regulation and diking on salmon habitat loss

Columbia River hydrology has changed drastically in response to human activities and climate at the same time that salmon populations have greatly decreased. To better understand the impacts of hydrologic alteration on salmo...Weizmann scientists invention moves forward: Cancer diagnosis technique gets FDA clearance
...anks to a diagnostic imaging technique that should soon be finding its way to medical establishments, many patients could be spared the pain and risk of biopsies. The technique, called 3TP, has recently received FDA clearance for use in the detection of breast and prostate cancer, and is slated for distri...Built-in eyeshade offers clue to prehistoric past

"Mature heart cells are naturally programmed to be anti-hypertophic, but mutation or the cumulative effects of cellular stress seems to restart a program of events that we've only seen in developing fetuses, " said Epstein.

The findings, soon to be published in the online edition of the journal Proceedings of the National Academy of Sciences, pinpoint one of the mechanisms underlying the link between mental and physical well-being.

"Over the next year, I think we'll get a clear idea of new roles these molecules play in early cell development an...Newly found gene resistant to economically crippling wheat disease
...nding plants with the pathogen resistance gene. As soon as a seedling sprouts, a small piece of the young leaf can be ground and then a DNA test can be run. This shows whether the markers are present. "Using the markers, in a few days you can tell which plants have the resistance gene and which don't," Go...Modifier gene controls severity of neurological disease in mice
...normal amount of functional Scn8a protein and died soon after birth. "The mutation in Scnm1 reduces the amount of Scn8a protein below the minimum threshold required for normal neurological function," Meisler says. To see if he could "rescue" B6 mice that had the lethal combination of mutations in Scn8a an...Research: Coral reefs' decline actually began centuries ago
...ing at the Red Sea, Australia or the Caribbean. As soon as human exploitation began, whether in the 1600s in Bermuda or tens of thousands of years ago in the Red Sea, the same scenarios were put into play."

In a new study soon to appear in Ecology Letters, Anurag Agrawal and Peter Kotanen (University of Toronto) present the most rigorous test of the hypothesis that parasites (insect herbivores) are less effective in attacking non-native plants compared to native plants.

...esity), starts off as a compensatory mechanism but soon runs out of control, says lead study author Lili A. Barouch, M.D., an assistant professor of medicine. As the heart muscle is worked harder, it bulks up. But after too much strain, it can become stiff and cease contracting.
