Using "microbubbles" and ultrasound can mean more targeted breast biopsies for patients with early breast cancer, helping to determine treatment and possibly saving those patients from undergoing a second breast cancer surgery, a new study in shows. http://phys.org/news215785028.html Medicine & Health Tue, 01 Feb 2011 12:17:22 EST news215785028 Microbubbles are much bigger than they sound. If all goes as planned during a demonstration project in eastern China, microbubble technology developed at the University of Utah has the potential to boost a wide range of environmental cleanup efforts around the world. Uses include removing oil and gas byproducts from water, removing organics and heavy metals from industrial sites, and removing harmful algae from lakes. http://phys.org/news206161394.html Space & Earth Wed, 13 Oct 2010 04:07:48 EST news206161394 (PhysOrg.com) -- A Harvard physicist has proposed the Earth could be cooled by pumping vast numbers of tiny bubbles into the sea to lower ocean temperatures and increase the water’s reflectivity. The same strategy could be used in rivers and lakes to reduce evaporation. http://phys.org/news189059955.html Space & Earth Mon, 29 Mar 2010 07:10:02 EST news189059955 Bone marrow stem cells suspended in X-ray-visible microbubbles dramatically improve the body's ability to build new blood vessels in the upper leg—providing a potential future treatment for those with peripheral arterial disease or PAD, say researchers at the Society of Interventional Radiology's 35th Annual Scientific Meeting in Tampa, Fla. http://phys.org/news187956474.html Medicine & Health Tue, 16 Mar 2010 11:08:09 EST news187956474 An imaging technique combining ultrasound and specially modified contrast agents may allow researchers to noninvasively detect cancer and show its progression, according to research published in the March issue of The Journal of Nuclear Medicine (JNM). The technique enables researchers to visualize tumor activity at the molecular level. http://phys.org/news186661066.html Medicine & Health Mon, 01 Mar 2010 10:40:05 EST news186661066 Duke University engineers have taken a first step toward a minimally invasive treatment of brain tumors by combining chemotherapy with heat administered from the end of a catheter. http://phys.org/news164378095.html Medicine & Health Tue, 16 Jun 2009 14:20:11 EST news164378095
