Cosmic bogs @ the London Catastrophes conference
You may think that peat bogs are among the least interesting places on Earth and you could be right. But according to speakers at Brunel University`s `Environmental Catastrophes` conference, that doesn`t stop them being excellent recorders of catastrophic environmental events like volcanic eruptions and cosmic influx. According to Dr Lars... view more... (2002-08-17)
Just 20 minutes of weekly housework boosts mental health
Just 20 minutes of any physical activity, including housework, in a week is enough to boost mental health, reveals a large study published ahead of print in the British Journal of Sports Medicine. view more (2008-04-10)
ESA's Envisat captures breath of volcano
Indonesia's Mount Gamkonora volcano is spewing hot ash and smoke into the air, as seen in this image taken by the MERIS instrument aboard ESA's satellite Envisat, causing more than 8000 people to be evacuated amid fears of an imminent eruption, according to officials. view more (2007-07-12)
Volcanic plumbing dictates development of deep-sea hydrothermal vents
After years of results that repeatedly dogged him, University of Oregon geologist Douglas R. Toomey decided to follow the trail of data surfacing from the Pacific Ocean. In doing so, he and his collaborators may have altered long-held assumptions involving plate tectonics on the ocean floor. view more (2007-03-22)
What goes down, must come up: Earth's leaky mantle
A new analysis of the processes that constantly stir the Earth's deep mantle is helping to explain how the mantle holds onto a portion of ancient noble gases that were trapped during the Earth's formation. view more (2009-05-28)
Scientists reveal fate of Earth's oceans
Scientists at The University of Manchester have uncovered the first evidence of seawater deep inside the Earth shedding new light on the fate of the planet's oceans, according to research published in Nature. view more (2006-05-11)

Sierra Nevada rose to current height earlier than thought, geologists say; implications for modeling global climate
Geologists studying deposits of volcanic glass in the western United States have found that the central Sierra Nevada largely attained its present elevation 12 million years ago, roughly 8 or 9 million years earlier than commonly thought. view more (2008-04-24)
After-school programs can increase physical activity of adolescent girls
Afterschool programs can modestly increase the amount of physical activity among girls in middle school, according to new results from the Trial of Activity for Adolescent Girls (TAAG), a multiple site, community based study supported by the National Heart, Lung, and Blood Institute (NHLBI) of the National Institutes of Health. view more (2008-03-14)
Blast From the Past: the `Minoan` eruption of Santorini (Thera) @ the London `Catastrophes` conference
The mid-second millennium `Minoan` eruption of Santorini (Thera) was one of the largest volcanic eruptions known to have occurred during the Holocene. It is also one of the most controversial, with the eruption being blamed for many far-reaching environmental and societal events, most notably the end of the Minoan civilisation on Crete. view more (2002-08-17)
Tectonic plates act like variable thermostat
Like a quilt that loses heat between squares, the earth's system of tectonic plates lets warmth out at every stitch. view more (2007-08-14)
Less than 3 percent of UK 11-year-olds take enough exercise
Less than 3 per cent of UK 11 year olds are taking enough exercise, suggests research published ahead of print in the Archives of Disease in Childhood. view more (2007-09-14)
Scientists lose instruments, gain first look at seafloor formation
Ordinarily, losing almost all of one's instruments would be considered a severe setback to any scientist. But when Maya Tolstoy, a marine geophysicist at the Lamont-Doherty Earth Observatory, a member of the Earth Institute at Columbia University, recently learned that two-thirds of the seismometers she placed on the floor of the Pacific Ocean... view more...

Longer bouts of exercise deter childhood obesity, new Queen's study confirms
Children who exercise in bouts of activity lasting five minutes or longer are less likely to become obese than those whose activity levels are more sporadic and typically last less than five minutes each, Queen's University researchers have discovered. view more (2009-03-19)
Moon's Escaping Gasses Expose Fresh Surface
Conventional wisdom suggests that the Earth's moon has seen no widespread volcanic activity for at least the last 3 billion years. Now, a fresh look at existing data points to much more recent release of lunar gasses. view more (2006-11-09)
Nevada Seismological Laboratory ranks top 10 states for earthquake activity
For many years, John Anderson, director of the Nevada Seismological Laboratory at the University of Nevada, Reno, has been telling citizens, reporters and other scientists from throughout the world that in terms of seismic activity in the 50 states, Nevada ranked as the third most active. view more (2006-11-21)
Earth's highest known microbial systems fueled by volcanic gases
Gases rising from deep within the Earth are fueling the world's highest-known microbial ecosystems, which have been detected near the rim of the 19,850-foot-high Socompa volcano in the Andes by a University of Colorado at Boulder research team. view more (2009-03-04)
Cooking with gas may increase inflammatory activity in the lungs
Cooking with gas may increase inflammatory activity in the lungs, suggests a study in Occupational and Environmental Medicine. Teflon filters were used to collect any particulate matter pollution emitted from gas and electric cookers. The residue was then applied to cultured cells that normally line the fine branching tubes of the lungs. The cells... view more... (2001-02-10)
Well before their teens, girls roughly half as physically active as boys
Well before they reach their teens, girls are almost half as physically active as boys, when it comes to regular vigorous exercise, shows research in the British Journal of Sports Medicine. The difference in physical activity between the sexes when they reach their teens has become relatively well known over recent years, but now this research... view more... (2001-07-24)
Ago2 and hematopoiesis
Argonaute 2 (Ago2) is unique among its family: It is the only one of the four mammalian Argonaute proteins that exhibits endonuclease "slicer" activity (facilitation of miRNA-guided cleavage of target mRNA). view more (2007-07-12)
