Our study reveals that so-called wax degradation on pine needles may develop from deposited particulate matter says Dr. JÃ rgen Burkhardt from the Institute of Crop science and Resource Conservation.
and 90s but sound explanations for both the degradation mechanism and the high correlation with forest damage have yet been missing Dr. Burkhardt reports.
This newly described mechanism was considered not in earlier explanations of Central European forest decline states Dr. Burkhardt.
Particularly because air concentrations of hygroscopic particles have increased largely within the last decades says Dr. Burkhardt.
We're discovering that predators are having important effects on shaping the make-up of ecosystems says Dr. Oswald Schmitz professor of ecology
Dr. Schmitz and his team created several controlled ecosystems: some that contained only native grasses and herbs others that had plants
It's going to force some thinking about the vital roles of animals in regulating carbon concludes Dr. Schmitz pointing to the fact that the UN's body of scientific experts who study climate change don't consider these multiplier effects in their models.
what that impact may be says Dr. David Tarpy an associate professor of entomology at North carolina State university

or more important in controlling blood pressure Dr. Kostis said. Our work describes the variability of blood pressure drop in response to weight loss according to a number of genetic polymorphisms added William J. Kostis Phd MD clinical
and the combination of weight loss and sodium restriction is more effective than either strategy alone noted Dr. William Kostis.
Physicians can put these findings to use today through a blood test or even saliva test that measures genotype Dr. John Kostis said They can compare the patient's genetic background with the polymorphisms that have been identified in the study
and counsel patients accordingly offering advice as to which type of intervention may be more successful in lowering that patient's blood pressure he said.
and less expensive evaluating weight sensitivity may be one way to identify individuals who may benefit more from weight loss as compared with other types of lifestyle interventions like cutting salt from their diet Dr. William Kostis said.

In a paper published online in Nature on March 31 Dr. Lemon's team discovered that Hepatitis a virus does not have an envelope
No one has shown that previously for a virus. It really blurs that classic distinction between these two types of viruses said Dr. Lemon.
Dr. Lemon believes the dual nature of Hepatitis a virus allows it to use the advantages of both virus types to enhance its survivability.
While no other virus has been shown to exhibit this particular behavior Dr. Lemon said that it is likely that Hepatitis a virus is not unique in its dual nature.
I think this is one of the most important things to come out of the study said Dr. Lemon.
Future studies will investigate the mechanisms behind the vaccine's effectiveness Dr. Lemon said. While it was thought previously that vaccine-induced antibodies attacked the virus outside of the cell the new findings suggest antibodies may actually be able to restrict viral replication within a cell.
Understanding how this really good vaccine works will help us in the future to develop better vaccines for other viruses that we are having difficulty developing vaccines for said Dr. Lemon.

The research has been led by Dr Charlotte Packman from UEA's school of Environmental sciences in collaboration with the Wildlife Conservation Society Cambodia Program and Birdlife International.
Dr Packman said: Tropical and flooded grasslands are among the most threatened ecosystems globally. The area around the Tonle Sap lake is the largest remaining tropical flooded grassland in Southeast asia.
Dr Packman added: Between 1995/1996 and 2005 the encroachment of scrubland was the major cause of grassland loss due to a reduction in traditional low intensity agricultural practices in the grasslands.

Dr Huntingford and colleagues used computer simulations with 22 climate models to explore the response of tropical forests in The americas Africa and Asia to greenhouse-gas-induced climate change.
Lead author Dr Chris Huntingford from the Centre for Ecology & Hydrology in the UK said The big surprise in our analysis is that uncertainties in ecological models of the rainforest are significantly larger than uncertainties from differences in climate projections.
Co-author Dr David Galbraith from the University of Leeds said This study highlights why we must improve our understanding of how tropical forests respond to increasing temperature and drought.
Co-author Dr Lina Mercado from the University of Exeter and the Centre for Ecology & Hydrology said Building on this study one of the big challenges that remains is to include in Earth system models a full representation of thermal acclimation and adaptation of the rainforest to warming.

Dr. Hecht said these results further underscore the need for enforceable public smoking bans and other measures to reduce passive inhalation of cigarette smoke.
and then to heart attacks so this lends more credence to enforcing smoking bans Dr. Hecht said.
Although his team did not use the standard Agatston score to assess CAC Dr. Hecht said this study further validates the utility of low-dose non-gated CT scans to measure the amount of plaque in the coronary arteries in nonsmokers exposed to secondhand tobacco smoke.
Lead researcher Dr Paul Dolman from UEA's school of Environmental sciences said: Deer management is often based on guesswork.
Dr Kristin Wäber who conducted the study while a Phd student at UEA said:
When I first heard what Dr. Kiang's team had found I was shocked said blood platelet expert Dr. Joel Moake a study co-author who holds joint appointments at Rice and BCM.
Moake whose research group was the first to describe how high shear stress could cause platelets to stick to VWF said I had thought that the condition might last for such a short time that it would be unmeasurable.
That is why Dr. Kiang's research is so important and makes it more likely that therapeutic interventions can be designed more rationally.
