Under the Water Framework Directive (WFD) (Directive 2000/60/CE), member states are required to achieve Good Water Status for water (continental, estuarine, subterranean and coastal water bodies) in Europe by 2015. Surface water quality is assessed taking into account the ecological and chemical status.

CHAMPAIGN, Ill. — Wind power is likely to play a large role in the future of sustainable, clean energy, but wide-scale adoption has remained elusive. Now, researchers have found wind farms' effects on local temperatures and proposed strategies for mediating those effects, increasing the potential to expand wind farms to a utility-scale energy resource.
ST. LOUIS – Thanks to a discovery by a Saint Louis University researcher, scientists have identified an important microRNA that may allow us to better control cholesterol levels in blood.
Led by Ángel Baldán, Ph.D., assistant professor of biochemistry and molecular biology at Saint Louis University and published in a recent issue of Proceedings of the National Academy of Sciences of the United States of America, the study found that the microRNA miR-33, may be key to controlling HDL, or "good" cholesterol levels.
AUGUSTA, Ga. – The most toxic free radical appears responsible for much of the lung damage that can result from oxygen therapy in the critically ill or injured, Medical College of Georgia researchers report.
Washington, D.C. (October 5, 2010) -- Protein molecules inside cells are constantly reorganizing themselves, driven by very tiny forces exerted by all the other molecules in their crowded environment. Most experimental techniques and theoretical/computational models are necessarily built around much greater driving forces. A new theoretical model reported in the Journal of Chemical Physics investigates the unfolding of fibronectin under gentler conditions.
Science’s annual survey of Top Employers polls employees in the biotechnology, biopharmaceutical, pharmaceutical, and related industries to determine the driving characteristics of the best employers and to determine the 20 best employers in these industries. Respondents to the web-based survey were asked to rate companies based on 23 characteristics, including financial strength, easy adaptation to change, and a research-driven environment.
Allergies occur when the defence mechanisms of the immune system malfunction and misread normal substances entering the body as invading pathogens. Antibodies are part of our biochemical arsenal for combating viruses, bacteria, parasites and other alien substances, but during an allergic reaction the antibody, known as IgE, is directed against usually harmless substances such as grass pollen, nuts, pets or eggs. Asthma and allergies are chronic diseases that reduce quality of life and pose an economic burden on society.
Therapeutic antibodies can be an efficient alternative when common drugs do not work anymore. However, antibodies obtained from blood of animals such as mice could not be used: The human immune system recognizes them as foreign and rejects them. In an international cooperation, scientists from the Helmholtz Centre for Infection Research (HZI) in Braunschweig, Germany have now succeeded in developing a promising approach to solve this problem; with the help of human stem cells they generated mice with a human immune system, which were then vaccinated to produce human monoclonal antibodies.
A study by two Florida State University biochemists makes an important contribution to science's understanding of a serious problem causing concern worldwide: the growing resistance of some harmful bacteria to the drugs that were intended to kill them.
Members of the European Parliament are calling on the Presidency of the EU and Member States to tackle urgently the problem of chronic non-communicable diseases that are responsible for 86% of all deaths in the WHO European Region. Their call is supported by an alliance of European health professionals, including ECCO – the European CanCer Organisation – and ESMO – the European Society for Medical Oncology.
San Diego, CA, October 5, 2010 – Influenza pandemics often come in multiple waves. As the one wave subsides, public health officials have to decide whether continuing vaccination programs is warranted to prevent or reduce a subsequent wave. In a new study published in the November issue of the American Journal of Preventive Medicine, researchers report on a new computer model that can be used to predict both subsequent-wave mechanisms and vaccination effectiveness.
Cutting back on sleep reduces the benefits of dieting, according to a study published October 5, 2010, in the Annals of Internal Medicine.
When dieters in the study got a full night's sleep, they lost the same amount of weight as when they slept less. When dieters got adequate sleep, however, more than half of the weight they lost was fat. When they cut back on their sleep, only one-fourth of their weight loss came from fat.
October 5, 2010 – Radiation therapy is used to treat more than half of all cancer cases, but patient response to therapy can vary greatly. Genetics is increasingly being recognized as a significant contributor to inter-individual response to radiation, but the biology underlying response remains poorly understood.
ROCHESTER, Minn. -- Mayo Clinic researchers have discovered biomarkers that could lead to personalized radiation treatments for cancer patients. The findings appear today online in the journal Genome Research.
"Overcoming resistance to radiation therapy would make treatment more effective for some individuals," says Liewei Wang, M.D., Ph.D., Mayo Clinic genomic researcher and senior author of the study. "Our findings may make it possible to one day develop novel therapies aimed at selected subgroups of cancer patients."
