Purdue study finds dairy better for bones than calcium carbonate
A Purdue University study shows dairy has an advantage over calcium carbonate in promoting bone growth and strength. view more (2009-04-29)
Hot springs microbes hold key to dating sedimentary rocks, researchers say
Scientists studying microbial communities and the growth of sedimentary rock at Mammoth Hot Springs in Yellowstone National Park have made a surprising discovery about the geological record of life and the environment. view more (2008-01-23)
Mixing without side effects
The range of micromixers offered by IMM is also suitable for processes susceptible to fouling, especially in fine chemistry and pharmaceutics. The new „Interdigital-separation-layer-mixers" are replacing the present generation of „Separation-layer-mixers". The new mixer system has been adapted especially to industrial... view more...

Dietary calcium is better than supplements at protecting bone health
Women who get most of their daily calcium from food have healthier bones than women whose calcium comes mainly from supplemental tablets. view more (2007-06-20)
A crystal clear view of chalk formation
Chalk crystallizes differently from the way we once thought it did. This discovery will allow the development of new scale inhibitors and other materials, and has also consequences for climate change. view more (2009-01-26)
UBC researcher gives first-ever estimate of worldwide fish biomass and impact on climate change
Are there really plenty of fish in the sea? University of British Columbia fisheries researcher Villy Christensen gives the first-ever estimate of total fish biomass in our oceans: Two billion tonnes. view more (2009-01-16)
Shellfish face an uncertain future in a high CO2 world
Overfishing and disease have decimated shellfish populations in many of the world's temperate estuarine and coastal ecosystems. view more (2009-05-27)
Calcium supplements may prevent fractures in elderly women who take them regularly
Calcium supplements may be an ineffective way of preventing bone fractures among the population of elderly women because of poor long-term compliance with the therapy, but appear to be effective for women who take the supplements regularly. view more (2006-04-25)
Oceans may soon be more corrosive than when the dinosaurs died
Increased carbon dioxide emissions are rapidly making the world's oceans more acidic and, if unabated, could cause a mass extinction of marine life similar to one that occurred 65 million years ago when the dinosaurs disappeared. view more (2006-02-21)
Origins of Life
The origin of life lies in unique ocean reefs, and scientists from the University of Miami's Rosenstiel School of Marine & Atmospheric Science have developed an approach to help investigate them better. view more (2006-11-20)
Engineered eggshells to help make hydrogen fuel
Engineers at Ohio State University have found a way to turn discarded chicken eggshells into an alternative energy resource. The patented process uses eggshells to soak up carbon dioxide from a reaction that produces hydrogen fuel. It also includes a unique method for peeling the collagen-containing membrane from the inside of the shells, so that... view more... (2007-09-27)
Watching rocks grow: Theory explains landscape of geothermal springs
Scientists at the University of Illinois at Urbana-Champaign have successfully modeled the spectacular landscapes seen at geothermal hot springs. view more (2006-07-06)
Relic of life in that Martian meteorite? A fresh look
Since the mid-1990s a great debate has raged over whether organic compounds and tiny globules of carbonate minerals imbedded in the Martian meteorite Allan Hills 84001 were processed by living creatures from the Red Planet. view more (2006-03-23)
Phytoplankton bounce back from abrupt climate change
Marine sediment cores contain calcareous plankton - single-celled organisms with a coating or shell of calcium carbonate - as fossils. These tiny photosynthesizing plants float in the ocean and move with the currents. view more (2006-02-17)
Measuring Calcium in Serpentine Soils
Serpentine soils contain highly variable amounts of calcium, making them marginal lands for farming. Successful management of serpentine soils requires accurate measurement of the calcium they hold. Research published this month in the Soil Science Society of America Journal shows that multiple measurement techniques are needed to accurately... view more... (2008-08-20)
University of Miami scientist uncovers miscalculation in geological undersea record
The precise timing of the origin of life on Earth and the changes in life during the past 4.5 billion years has been a subject of great controversy for the past century. view more (2008-09-11)
Ocean acidification threatens cold-water coral ecosystems
Corals don't only occur in warm, sun-drenched, tropical seas; some species are found at depths of three miles or more in cold, dark waters throughout the world's oceans. view more (2006-04-03)
MIT, Harvard offer solution to Mars enigma
Planetary scientists have puzzled for years over an apparent contradiction on Mars. Abundant evidence points to an early warm, wet climate on the red planet, but there's no sign of the widespread carbonate rocks, such as limestone, that should have formed in such a climate. view more (2007-12-26)
Calcium important for nursing mothers' oral health
Mothers who breastfeed should be sure to have enough Calcium in their diet, or may risk bone loss around their teeth and gums, according to a new study that appears in the January issue of the Journal of Periodontology (JOP). view more (2007-01-10)
Regardless of global warming, rising CO2 levels threaten marine life
Like a piece of chalk dissolving in vinegar, marine life with hard shells is in danger of being dissolved by increasing acidity in the oceans. view more (2007-03-09)
