Species unique to tidal marshes face threats
Tidal marshes cover only about 45,000 square kilometers worldwide-about the area of Denmark. In comparison with other habitats, tidal marshes support few nonaquatic vertebrate species, but their unique characteristics have led to the evolution of species and subspecies that are endemic (found... view more (2006-08-01)

Indigenous water frogs under threat
Indigenous water frogs can be crowded out by immigrant or imported species. This is the finding of a Franco-German study. The scientists investigated water frog populations in France and Northern Spain and noticed that the marsh frog (Rana ridibunda), which normally occurs only in Eastern Europe,... view more (2007-11-30)

Helping good bacteria win the war on dental disease
Good bacteria growing in dental plaque could help fight off bugs that cause gum disease and tooth decay if they are given a competitive edge, according to research presented today (Monday 16 September) at the Society for General Microbiology autumn meeting at Loughborough University. "We've... view more (2002-08-28)

Underwater wings for tidal power
A NOVEL machine that generates electricity from marine tides will be put to the test off the Scottish coast next year. Called the Snail, it uses the flow of water over wings to anchor it to the seabed. This will allow it to operate at a greater range of sites than rival models, its designers say.... view more (2003-09-24)

Healthy coastal wetlands would adapt to rising oceans
Tidal marshes, which nurture marine life and reduce storm damage along many coastlines, should be able to adjust to rising sea levels and avoid being inundated and lost, if their vegetation isn't damaged and their supplies of upstream sediment aren't reduced, a new Duke University study suggests.   view more (2007-03-29)

'Magma P.I.' unearths clues to how crust was sculpted
About a decade ago, Johns Hopkins University geologist Bruce Marsh challenged the century-old concept that the Earth's outer layer formed when crystal-free molten rock called magma oozed to the surface from giant subterranean chambers hidden beneath volcanoes.   view more (2007-12-04)

Measures to assess potential lung injury during ventilation inadequate
Ventilator-induced injury to the lungs can contribute to prolonged respiratory failure and even death among patients with acute respiratory distress syndrome (ARDS).   view more (2008-08-15)

Supercomputer simulations shed light on cataclysmic variable flashes.
New supercomputer simulations may help explain periodic bursts of light emitted by compact binary star systems.   view more (2005-03-31)

Safer shipping by predicting sand wave behaviour
Dutch researcher Joris van den Berg has developed a mathematical model to predict the movement of sand waves. Sand waves are formed by an interaction between the tidal current and sand.   view more (2007-07-13)

Study shows that parasites form the thread of food webs
Scientists have discovered that parasites are suprisingly important in food webs and their findings appear in a report published this week in the Early Edition of the on-line version of the Proceedings of the National Academy of Sciences.   view more (2006-07-13)

Compact tidal generator could reduce the cost of producing electricity from flowing water
What happens if you run an electric motor backwards? That is exactly what researchers Dr Steve Turnock and Dr Suleiman Abu-Sharkh from the University of Southampton asked themselves after they had successfully built an electric motor for tethered underwater vehicles.   view more (2006-06-14)

Earthquakes Happen at Full Moon
Russian physicists have found that flashes of neutron radiation from the Earth surface are bound to increasing in seismic activity. They believe that this phenomenon can be used as a novel kind of earthquake foreboding. The researchers of the Department of Cosmic Radiation of the Research... view more (2001-02-02)

Surprising Killer of Southeastern Salt Marshes: Common Sea Snails
Periwinkles, the spiral-shelled snails commonly found along rocky U.S. shorelines, play a primary role in the unprecedented disappearance of salt marsh in the southeastern states, according to new research published in Science.   view more (2005-12-16)

Iraq's marshes show progress toward recovery
Reflooding of Iraq's destroyed Mesopotamian marshes since 2003 has resulted in a "remarkable rate of reestablishment" of native invertebrates, plants, fish, and birds, according to an article in the June issue of BioScience.   view more (2006-05-31)

Scientists discover ancient protein and DNA sequences in same fossil
For the first time in the world, researchers at the University of Newcastle upon Tyne, UK, along with collaborators at the University of Oxford, Harvard University, and Michigan State University have uncovered two genetically informative molecules from a single fossil bone. In addition to the... view more (2002-11-12)

From Europa To Sedna - Life Beneath The Ice In The Outer Solar System?
At present, we know of no worlds beyond our Earth where life exists. However, primitive organisms on our planet have evolved and adapted over billions of years, colonising the most inhospitable places. Since life seems to gain a foothold in the most hostile environments, it seems distinctly... view more (2004-03-25)

Coastal retreat in face of rising sea levels found to be influenced by wildfires
The retreat of coastlines due to rising sea levels may be accelerated by wildfires, a Duke University researcher has discovered.   view more (2005-10-18)

Rising tides intensify non-volcanic tremor in Earth's crust
For more than a decade geoscientists have detected what amount to ultra-slow-motion earthquakes under Western Washington and British Columbia on a regular basis, about every 14 months.   view more (2007-11-26)

Increased flow of groundwater after earthquakes suggests oil extraction applications
The most obvious manifestation of an earthquake is the shaking from seismic waves that knocks down buildings and rattles people. Now researchers have established a more subtle effect of this shaking—it increases the permeability of rock to groundwater and other fluids.   view more (2006-06-29)

Microfossils show promise in prospecting climate history
In 2004 and now in 2005, the hurricane seasons have been horrifyingly intense - so how bad is the long-range forecast? Based on a century of data, meteorologists currently believe that a 30-year lull in hurricane activity is over and we are at the beginning of a new multi-decade period of larger... view more (2005-10-31)

Preventing ventilation induced lung injury depends on giving the right number of 'sighs'
Ventilation therapy burst into the public consciousness more than 60 years ago with the "iron lung" and the polio epidemic.   view more (2006-07-25)

Livestock in salt marshes help farmers and geese
If livestock are allowed to graze in salt marshes in the Wadden Sea area, the vegetation remains in a good condition for the hundreds of thousands of Brent Geese which forage there en route to Siberia. When such grazing does not take place on a large scale, the geese are likely to become more... view more (2002-10-24)

Dead famous: Research says 18th century Obituaries Sparked Modern Cult of Celebrity
Research by the University of Warwick shows how death gave birth to the modern cult of celebrity as the sudden rise in the popularity of obituaries of unusual people in the 1700s provided people with the 18th Century equivalent of a celebrity gossip magazine.    view more (2008-11-06)

Titan's seas are sand
Until a couple of years ago, scientists thought the dark equatorial regions of Titan might be liquid oceans.   view more (2006-05-05)

Beach pollution is worst during new and full moon
A new study of 60 beaches in Southern California suggests that water pollution varies with the lunar cycle, reaching the highest levels when tides are ebbing during the new and full moon.   view more (2005-08-02)
