Corn Yield Stability Varies with Rotations, Fertility
Understanding temporal variability in crop yields has implications for sustainable crop production, particularly since greater fluxes in crop yields are projected with global climate change. view more (2009-07-22)
First German Center for Modeling and Simulation in the Life Sciences Established in Heidelberg
The first German center for modeling and simulation in the life sciences (BIOMS) opens today in Heidelberg. In international terms, Heidelberg is already an outstanding location for the life sciences and scientific computing. At the new Center, modeling and computer simulation will be used for research on biological systems. With these methods... view more... (2004-02-12)
Recycling water in buildings by microbes
New information about how households and businesses can recycle and re-use their own water suggests that a submerged membrane bio-reactor could be the best method. The aim is to make water a more sustainable resource by reducing the amount that needs to be treated by large, central facilities. The work is being carried out in Cranfield... view more...

Research explores interactions between nanomaterials, biological systems
The recent explosion in the development of nanomaterials with enhanced performance characteristics for use in commercial and medical applications has increased the likelihood of people coming into direct contact with these materials. view more (2009-06-22)
Quantum Systems Could Flout Physics Law
Scientists in the Weizmann Institute's Faculty of Chemistry, together with colleagues in Germany, have made a startling prediction: Simply 'taking the temperature' of certain quantum systems at frequent intervals might cause them to disobey a hard and fast rule of thermodynamics. view more (2008-06-03)
LSU scientist finds evidence of 'rain-making' bacteria
Brent Christner, LSU professor of biological sciences, in partnership with colleagues in Montana and France, recently found evidence that rain-making bacteria are widely distributed in the atmosphere. view more (2008-02-29)
Just like old times: Generating RNA molecules in water
A key question in the origin of biological molecules like RNA and DNA is how they first came together billions of years ago from simple precursors. view more (2009-11-23)
Mean Population Size Increases with Diversity
A long-standing debate in ecology has been the effect of diversity on the temporal stability of biological systems. Ecological theory predicts that the stability of populations should decline as community diversity increases, in part, because population size is assumed to decline with community richness. In the February issue of Ecology Letters,... view more... (2003-01-28)
Patients with chronic illness not benefiting from advances in care
Many patients with chronic diseases are not benefiting from advances in care because of a lack of financial and staff resources, inadequate information systems, and doctors' heavy workload, argue US researchers in this week's BMJ. They assessed the extent to which evidence-based chronic care management processes and computer based clinical... view more... (2002-10-22)
Less than half of medical students understand health care system
Less than half of graduating medical students in the U.S. say they received adequate training in understanding health care systems and the economics of practicing medicine. view more (2009-10-01)
Concern for European public health as EU border extends to the east (p 1339, 1389)
Public-health experts writing in this week's issue of THE LANCET caution that the widening of the European Union (EU) to the east could have potentially adverse effects on public health - both for the new member countries, many of whom have poor health-care infrastructure, and for existing EU members. In May, 2004, ten new member states... view more... (2004-04-21)
Alien plants attack using 'resource conservation' as weapon, researchers say
One of the most serious and least understood threats to the world's ecosystems is the problem of invasive species-exotic plants, animals and other organisms that are brought into habitats and subsequently spread at a rapid rate, often replacing native species and reducing biodiversity. view more (2007-05-02)
Mathematicians help unlock secrets of the immune system
A group of scientists, led by mathematicians, has taken on the challenge of building a common model of immune responses. view more (2007-10-10)
European space systems support management of natural and technological disasters
The European Space Agency, ESA, and the French Space Agency, CNES, signed a charter on 20 June 2000 to promote cooperation among space system operators in deploying their systems in the event of major natural or technological disasters. The charter was signed by Mr Antonio Rodot' , ESA's Director General, and Mr Gérard Brachet, Director... view more... (2000-06-22)
Semiconductor membrane mimics biological behavior of ion channels
A semiconductor membrane designed by researchers at the University of Illinois could offer more flexibility and better electrical performance than biological membranes. view more (2007-07-13)
Scientists discover new method of observing interactions in nanoscale systems
Scientists have used new optical technologies to observe interactions in nanoscale systems that Heisenberg's uncertainty principle usually would prohibit, according to a study published Jan. 17 in the journal Nature. view more (2008-01-17)
Scientists discover key factor in regulating placenta and fetal growth
Scientists funded by the Biotechnology and Biological Sciences Research Council (BBSRC) have shown that a common biological protein molecule called SHP-2 is crucial for encouraging placenta growth. view more (2009-09-21)
Nature inspires new highly specific drugs and organic products
The best place to seek novel compounds for pharmaceutical drugs, alternative energy sources, and a host of industrial applications, is within natural systems that have evolved over millions of years. view more (2008-09-03)
3D Molecular Sciences Presents its New Patented 3D Encoded Particle Array Tool for Multiplexing Bioassays at BioArray Europe
3D Molecular Sciences presented a poster providing new assay data on the Company's multiplexing enabling platform technology for molecular medicine at the BioArray Europe conference, taking place in Cambridge, UK, on 1 October 2002. The new patented assay system consists of microfabricated encoded particles of a variety of designs, attachment... view more... (2002-10-01)
Prenatal alcohol exposure can alter circadian rhythms in offspring
Children with fetal alcohol spectrum disorders (FASD) suffer from a variety of behavioral alterations. For example, they may exhibit alterations in sleeping and eating patterns, which may indicate that their circadian systems - which control biological rhythms - have been affected by alcohol exposure during development. view more (2006-04-24)
