Biodegradable microspheres deliver time release vaccines, stimulate different immune response
A new vaccine delivery system using microspheres of a biodegradable polymer may not only reduce the need for booster shots in some cases, but also appears to stimulate an immune response that traditional vaccines do not. view more (2007-03-01)
Method to deliver molecules within embryonic stem cells improves differentiation
Embryonic stem cell therapies have been proposed for regenerative medicine and tissue replacement after injury or disease. However, the inability of stem cells to efficiently develop into the desired specific cell type - such as muscle, skin, blood vessels, bone or neurons - now limits the potential clinical utility of this therapy. view more (2008-04-10)
Tiny radioactive spheres effectively treat cancer that has spread to the liver
Placing tiny radioactive spheres directly into the liver through its blood supply halted growth of tumors that had spread to the organ in 71 percent of patients tested in a small clinical trial, researchers from Mayo Clinic Jacksonville report. view more (2007-10-30)
New fabricated material changes color instantly in response to external magnetic field
A research team led by a chemist at the University of California, Riverside has fabricated microscopic polymer beads that change color instantly and reversibly when external magnetic fields acting upon the microspheres change orientation. view more (2009-06-17)
New vaccine approach prevents/reverses diabetes in lab study at Children's Hospital of Pittsburgh
Microspheres carrying targeted nucleic acid molecules fabricated in the laboratory have been shown to prevent and even reverse new-onset cases of type 1 diabetes in animal models. The results of these studies were reported by diabetes researchers at the John G. Rangos Sr. Research Center at Children's Hospital of Pittsburgh of UPMC and Baxter... view more... (2008-05-29)
New Jefferson Trial to Test Radiation-Emitting Beads Against Advanced Liver Cancer
Liver cancer specialists at Jefferson's Kimmel Cancer Center in Philadelphia are beginning an 18-month study of a new treatment for liver cancer. The therapy entails injecting tiny beads that emit small amounts of radiation into the liver's main artery while also blocking the blood supply feeding the cancer's growth. view more (2008-02-13)
Bone research that grows on you
Rapid and guided healing of bones has moved a step closer with research by two biomedical engineering students who have found new ways to deliver bone growth enhancers directly to broken or weakened bones. view more (2006-11-01)
Penn researchers start new clinical trial to examine ways to improve treatment of uterine fibroids
Researchers at the University of Pennsylvania School of Medicine are working on ways to improve the results of a non-surgical method to treat fibroids. view more (2006-05-30)
MIT's 'electronic nose' could detect hazards
A tiny "electronic nose" that MIT researchers have engineered with a novel inkjet printing method could be used to detect hazards including carbon monoxide, harmful industrial solvents and explosives. view more (2007-11-12)
New gecko-like adhesive shakes off dirt
Researchers at the University of California, Berkeley, are continuing their march toward creating a synthetic, gecko-like adhesive, one sticky step at a time. Their latest milestone is the first adhesive that cleans itself after each use without the need for water or chemicals, much like the remarkable hairs found on the gecko lizard's toes. view more (2008-09-10)
Future for radioembolisation in patients with advanced hepatocellular carcinoma
Copenhagen, Denmark, Friday 24 April: Radioembolisation with Yttrium-90 (Y-90) glass microspheres is a safe and effective treatment for patients with advanced HCC ± portal vein thrombosis, according to new research presented today at EASL 2009, the Annual Meeting of the European Association for the Study of the Liver in Copenhagen, Denmark. view more (2009-04-24)
Current technology for brain cooling unlikely to help trauma patients
Attempts to cool the brain to reduce injury from stroke and other head trauma may face a significant obstacle: current cooling devices can't penetrate very deeply into the brain. view more (2006-08-07)
New Electrostatic-based DNA Microarray Technique Could Revolutionize Medical Diagnostics
The dream of personalized medicine - in which diagnostics, risk predictions and treatment decisions are based on a patient's genetic profile - may be on the verge of being expanded beyond the wealthiest of nations with state-of-the-art clinics. view more (2008-07-01)
Chemotherapy gel may fight breast cancer and reduce breast deformity
Women who undergo surgery for breast cancer followed by radiation therapy often experience breast deformities that can only be corrected through reconstructive surgery. view more (2006-04-25)
Light-sensitive particles change chemistry at the flick of a switch
A light-sensitive, self-assembled monolayer that provides unique control over particle interactions has been developed by scientists at the University of Illinois at Urbana-Champaign. view more (2006-03-27)
A Penn physics study: Of traffic jams, beach sands and the zero-temperature jamming transition
Researchers in condensed matter physics at the University of Pennsylvania and the University of Chicago have created an experimental and computer model to study how jamming, the physical process in which collections of particles are crammed together to behave as solids, might affect the behavior of systems in which thermal motion is important,... view more...

Mayo Clinic researchers use magnetic attraction to improve stents, reduce blood clot risk
Mayo Clinic heart researchers have devised a new strategy to improve the effectiveness and safety of heart stents, which are used to open narrowed blood vessels and have been the recent subject of clotting concerns. view more (2006-11-03)
INL-led team achieves nuclear fuel performance milestone
Researchers at the U.S. Department of Energy's Idaho National Laboratory, in partnership with three other science and engineering powerhouses, reached a major domestic milestone relating to nuclear fuel performance on March 8. view more (2008-03-11)
MIT works toward novel therapeutic device
MIT and University of Rochester researchers report important advances toward a therapeutic device that has the potential to capture cells as they flow through the blood stream and treat them. Among other applications, such a device could zapp cancer cells spreading to other tissues, or signal stem cells to differentiate. view more (2007-10-23)
'Smart' materials get smarter with ability to better control shape and size
A dynamic way to alter the shape and size of microscopic three-dimensional structures built out of proteins has been developed by biological chemist Jason Shear and his former graduate student Bryan Kaehr at The University of Texas at Austin. view more (2008-07-07)
