Bone cement only controls bacteria for a few days after the operation
Dutch research has revealed that bone cement containing antibiotics can effectively control infections around prostheses but only during the first few days after the implantation. For the past 30 years bone cement, which affixes hip and knee prostheses to the bone, has contained antibiotics and from the start, the usefulness of this has been... view more... (2003-10-10)
Novel experiments on cement yield concrete results
Using a brace of the most modern tools of materials research, a team from the National Institute of Standards and Technology (NIST) and Northwestern University has shed new light on one of mankind's older construction materials—cement. view more (2007-04-02)
Cone-beam CT: Just as useful as MDCT before and after percutaneous vertebroplasty
Cone-beam CT which is believed to deliver less radiation than MDCT is just as useful when evaluating patients before and after percutaneous vertebroplasty according to a study performed at the Department of Clinical Radiology, Kyushu University, Fukoka, Japan. view more (2008-11-04)
Waste water treatment plant mud used as 'green' fuel
Catalan scientists have shown that using mud from waste water treatment plants as a partial alternative fuel can enable cement factories to reduce their CO2 emissions and comply with the Kyoto Protocol, as well as posing no risk to human health and being profitable. view more (2009-06-24)
'Green' research at Louisiana Tech results in new geopolymer concrete technology
Dr. Erez Allouche, assistant professor of civil engineering at Louisiana Tech University and associate director of the Trenchless Technology Center, is conducting innovative research on geopolymer concrete and providing ways to use a waste byproduct from coal fired power plants and help curb carbon dioxide emissions. view more (2009-09-30)
TREATING POLLUTED LAND WITH CARBON DIOXIDE
First a granular binder containing products which react with carbon is added to the contaminated soil and then carbon dioxide is pumped into the mixture. The three components rapidly combine to produce a cement that is very stable, and although marginally more expensive is immediately available for development. The land can then be used for... view more... (1999-11-25)
New expensive back procedure exposed as ineffective
A world-first study involving Monash University and the Cabrini Research Institute in Melbourne has revealed the injection of bone cement into broken vertebrae is not an effective treatment for patients suffering painful osteoporotic fractures. view more (2009-08-06)
National Insect Week 2004
This summer will see the launch of National Insect Week, a new initiative from the Royal Entomological Society which aims to raise the profile of insects among the British public, and to encourage the study of entomology. National Insect Week is sponsored by Castle Cement and has the support of the Darwin Centre at the Natural History Museum in... view more... (2004-05-12)
Bioactive cement scaffold may improve bone grafts
A new technology for implants that may improve construction or repair of bones in the face, skull and jaw, has been developed by researchers from the American Dental Association Foundation (ADAF) and the National Institute of Standards and Technology (NIST). view more (2006-04-18)
Engineering to protect brittle bones
Leeds University engineer Dr Ruth Wilcox, 27, is on a mission - to help people with the brittle bone disease osteoporosis. She has just won a Post-Doctoral Research Fellowship from the Royal Academy of Engineering, starting 1 August, which will enable her to devote the next five years of her research to improving treatment of patients with... view more...

Studies unclear whether spinal cement procedure improves back pain
A procedure that fills in fractured vertebrae with injected cement has not been shown to improve a person's back pain or quality of life, according to a new analysis of studies. view more (2006-05-15)
New technique offers relief for patients with spinal tumors
A radiologist at the University of California, San Diego (UCSD) School of Medicine has developed a new procedure to treat fractured vertebrae caused by spinal tumors, a procedure that may decrease the risk of complications, which are experienced by 5 to 10% of patients with malignant tumors of the spine. view more (2006-05-08)
MIT: Nanoengineered concrete could cut CO2 emissions
While government leaders argue about the practicality of reducing world emissions of carbon dioxide, scientists and engineers are seeking ways to make it happen. view more (2007-01-30)
Cement's basic molecular structure finally decoded
In the 2,000 or so years since the Roman Empire employed a naturally occurring form of cement to build a vast system of concrete aqueducts and other large edifices, researchers have analyzed the molecular structure of natural materials and created entirely new building materials such as steel, which has a well-documented crystalline structure at... view more...

How Solid Is Concrete's Carbon Footprint?
Many scientists currently think at least 5 percent of humanity's carbon footprint comes from the concrete industry, both from energy use and the carbon dioxide (CO2) byproduct from the production of cement, one of concrete's principal components. view more (2009-05-19)
Vertebroplasty improves back pain, activity level, Mayo Clinic study reports
A Mayo Clinic study has found patients report less back pain at rest and while active following vertebroplasty, a procedure in which medical cement is injected into painful compression fractures in the spinal vertebrae due to osteoporosis. view more (2005-12-30)
Vertebroplasty heals fractures but may cause others, Mayo Clinic study finds
A new Mayo Clinic study finds that vertebroplasty, a procedure used to treat painful compression fractures in the spinal vertebrae due to osteoporosis, appears to increase the risk for new fractures in adjacent vertebrae. view more (2006-01-17)
CO2 emissions booming, shifting east, researchers report
Despite widespread concern about climate change, annual carbon dioxide emissions from burning fossil fuels and manufacturing cement have grown 38 percent since 1992, from 6.1 billion tons of carbon to 8.5 billion tons in 2007. view more (2008-09-25)
Swishing once a day with mouthrinse poses no harm to dental work
