Resilience concepts poised to aid management of coastal marine ecosystems
The January 2008 issue of BioScience includes a special section entitled "Managing for Resilience in Coastal Marine Ecosystems." The four articles in the section highlight different aspects of attempts to incorporate modern concepts from mathematical ecology into ecosystem-based management of coastal marine areas. view more (2008-01-02)
Brownian motion under the microscope
An international group of researchers from the EPFL (Ecole Polytechnique Fédérale de Lausanne), the University of Texas at Austin and the European Molecular Biology Laboratory in Heidelberg, Germany have demonstrated that Brownian motion of a single particle behaves differently than Einstein postulated one century ago. view more (2005-10-12)
MIT researchers build tiny batteries with viruses
MIT scientists have harnessed the construction talents of tiny viruses to build ultra-small "nanowire" structures for use in very thin lithium-ion batteries. view more (2006-04-07)
Study identifies another strategy for normalizing tumor blood supply
Manipulating levels of nitric oxide (NO), a gas involved in many biological processes, may improve the disorganized network of blood vessels supplying tumors, potentially improving the effectiveness of radiation and chemotherapy. view more (2008-02-21)
NIST imaging system maps nanomechanical properties
The National Institute of Standards and Technology (NIST) has developed an imaging system that quickly maps the mechanical properties of materials-how stiff or stretchy they are, for example-at scales on the order of billionths of a meter. view more (2007-12-13)
MIT researchers make carbon nanotubes without metal catalyst
Carbon nanotubes - tiny, rolled-up tubes of graphite - promise to add speed to electronic circuits and strength to materials like carbon composites, used in airplanes and racecars. view more (2009-08-11)
VIP's importance to temperature regulation may be pre-empted by substance P
An elusive neurotransmitter pathway in the skin may have been isolated by University of Oregon researchers, a discovery that, if confirmed, would be a leap forward in understanding how temperature regulation occurs. view more (2006-10-25)
Soil emissions are much-bigger-than-expected component of air pollution
Nitrogen oxides produced by huge fires and fossil fuel combustion are a major component of air pollution. They are the primary ingredients in ground-level ozone, a pollutant harmful to human health and vegetation. view more (2005-06-07)
Cluster opens a new window on 'magnetic reconnection' in the near-Earth space
Plasma physicists have made an unprecedented measurement in their study of the Earth's magnetic field. Thanks to ESA's Cluster satellites they detected an electric field thought to be a key element in the process of 'magnetic reconnection'. view more (2007-03-13)
Filter That Makes Viruses Adhere
Siberian researchers have developed a biologically active sorbent of a new generation. The sorbent provides for the 100-percent efficient water purification from microorganisms and bacteriophages. Microbiological researches were performed with partial support of the U.S. Civilian Research and Development Foundation (CRDF) grant. view more (2005-03-25)
New Models of Weather Pattern
For a mathematician, Joseph Biello spends a lot of time thinking about the weather. But the UC Davis assistant professor isn't looking out the office window. He is using mathematical theory to build a model of the Madden-Julian Oscillation, a tropical weather pattern that influences drought and rainfall in the western U.S. view more (2005-12-12)
heory provides more precise estimates of large-area biodiversity
Ask biologists how many species live in a pond, a grassland, a mountain range or on the entire planet, and the answers get increasingly vague. Hence the wide range of estimates for the planet's biodiversity, predicted to be between 2 million and 50 million species. view more (2009-07-10)
Leveling the field for babies with persistent pulmonary hypertension
If he can figure out which babies will be born unable to breathe properly, Dr. Stephen M. Black thinks he can help change that. view more (2006-10-09)
Horphag's Prelox provides over-the-counter solution
For couples worldwide, erectile dysfunction (ED) is one of the leading contributors to a man's inability to perform. As millions of men in America each year look for a solution, many seek alternative treatments to prescription medications and surgery that may have dangerous side effects. view more (2007-12-04)
Robust sensor yields cleaner car exhaust
Emissions from cars have to be reduced further in order to meet today's environmental demands. A new and robust exhaust sensor developed by researchers at Linköping University in Sweden has proven to meter the consistency of exhaust gases extremely well and is now on its way to the market. view more (2005-04-27)
Toward a quantum computer, one dot at a time
Researchers at the University of Pittsburgh have developed a way to create semiconductor islands smaller than 10 nanometers in scale, known as quantum dots. view more (2006-01-20)
Nanohelix structure provides new building block for nanoscale piezoelectric devices
A previously-unknown zinc oxide nanostructure that resembles the helical configuration of DNA could provide engineers with a new building block for creating nanometer-scale sensors, transducers, resonators and other devices that rely on electromechanical coupling. view more (2005-09-09)
Carbon nanotubes made into conductive, flexible 'stained glass'
Carbon nanotubes are promising materials for many high-technology applications due to their exceptional mechanical, thermal, chemical, optical and electrical properties. view more (2008-04-09)
raGraphene and gallium arsenide: two perfect partners find each other
It is the marriage of two top candidates for the electronics of the future, both excentric and extremely interesting: Graphene, one of the partners, is an extremely thin fellow and besides, very young. view more (2009-09-17)
A call for standardized measurement of outcomes in depression treatment
Rhode Island Hospital and Brown University researchers are calling on clinicians to adopt a standardized measurement of outcomes when treating depression. The commentary was published in the June edition of Primary Psychiatry. view more (2008-06-10)
