Blood-compatible nanoscale materials possible using heparin
Researchers from Rensselaer Polytechnic Institute have engineered nanoscale materials that are blood compatible using heparin, an anticoagulant. The heparin biomaterials have potential for use as medical devices and in medical treatments such as kidney dialysis. view more (2006-05-08)
Building a Terabyte Archive at the ESO HQ
This event marks the closing of the data flow loop at the VLT for the first time and the successful culmination of more than 5 years of hard work by ESO engineers and scientists to implement a system for efficient and effective scientific data flow. This was achieved by a cross-organization science operations team involving staff in Chile and... view more... (1999-06-21)
An alternative treatment for hypervascular hepatocellular carcinoma
HCC is the fifth most common cancer in the world and the third most frequent cause of cancer-related death. Only about 20% of HCC patients are eligible for surgical resection. view more (2009-06-15)
Researchers at UCLA engineering discover theoretical model to predict jamming
Researchers at the UCLA Henry Samueli School of Engineering and Applied Science have come up with a theoretical model to predict when granular materials become jammed. view more (2008-04-28)
Using fMRI to study brain development
Functional magnetic resonance imaging (fMRI) is a powerful noninvasive tool for studying brain activity in both humans and experimental animals. view more (2007-12-03)
Clotted fat in the blood can be separated with ultrasound
An entirely new method for purifying blood has been developed at the Lund Institute of Technology, LTH, in Sweden. The blood is led out in hair-thin channels and is processed with ultrasound. A company in the neighboring research village IDEON is now perfecting the first medical application: a treatment to separate out clotted fat so-called fat... view more... (2002-09-23)
Technology could enable computers to 'read the minds' of users
Tufts University researchers are developing techniques that could allow computers to respond to users' thoughts of frustration - too much work - or boredom-too little work. Applying non-invasive and easily portable imaging technology in new ways, they hope to gain real-time insight into the brain's more subtle emotional cues and help provide a... view more...

Natural aorta grafts have few side effects for infection-prone patients
A vascular surgery technique pioneered at UT Southwestern Medical Center, in which veins are removed from the thigh to repair the aorta does not create blood-flow problems and painful side effects in a majority of patients, researchers report. view more (2007-09-11)
Jefferson researchers want to learn if heart defect 'at heart' of some migraines
Researchers of the heart and headaches at Thomas Jefferson University Hospital are combining efforts to determine if a common heart defect may be the cause of some forms of migraine headaches. view more (2007-04-23)
Study reveals how blood flow force prevents clogged arteries
Machines on cell surfaces, mechanical and lifeless as bed springs, protect blood vessels by responding to blood flow force, according to research published today in the Journal of Cell Biology. view more (2008-08-26)
UF researchers test stem cell therapy for heart patients
University of Florida doctors on Wednesday (Oct. 3) treated their first patient enrolled in a new study designed to test whether injecting stem cells into the heart helps restore blood flow to the organ by prompting new blood vessels to grow. view more (2007-10-05)
Underwater wings for tidal power
A NOVEL machine that generates electricity from marine tides will be put to the test off the Scottish coast next year. Called the Snail, it uses the flow of water over wings to anchor it to the seabed. This will allow it to operate at a greater range of sites than rival models, its designers say. Tidal flows have the potential to supply large... view more... (2003-09-24)
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)
Natural compound and exercise boost memory in mice
A natural compound found in blueberries, tea, grapes, and cocoa enhances memory in mice, according to newly published research. This effect increased further when mice also exercised regularly. view more (2007-05-30)
Pregnancy situations have impact on brain development in pre-term infants
Brain development in infants who are born very prematurely is still incomplete. Factors that cause premature birth may have an impact on the development of the premature infant's brain both during pregnancy and later on after birth. view more (2008-08-28)
A Delicate Blood Balancing Act
As you sit and read this article, between four and six litres of blood are flowing around your body. Have you ever thought about what is involved when this flow is stopped somewhere and a blood clot forms? Vascular haemostasis is the delicate balancing act between keeping blood in its fluid state under normal circumstances and forming a blood clot... view more... (2003-03-13)
Optimal systemic and splanchnic hemodynamic state after living-donor liver transplantation
Almost all adult recipients who undergo LDLT develop liver cirrhosis with long-term portal hypertension. Portal hypertension results in vascular dilatation and collateral pathways. Thus, various alterations in systemic hemodynamics and splanchnic circulation occur, and adult recipients often present characteristic hemodynamics before LDLT. view more (2007-11-14)
Gas explosions: A new way to study phantom traffic jams
A University of Alberta researcher has devised a new theoretical approach to studying phantom traffic jams. Normally a traffic tie-up happens when vehicles reach a bottleneck and traffic flow is reduced, or in the case of an accident, halted completely. view more (2009-06-09)
Minerals go 'dark' near Earth's core
Minerals crunched by intense pressure near the Earth's core lose much of their ability to conduct infrared light, according to a new study from the Carnegie Institution's Geophysical Laboratory. view more (2006-05-26)
Hanover Trade Fair 2003: The six-pack mixer
Flexible liquid distribution system for numbering-up in micro process engineering In theory it sounds simple - numbering-up provides more throughput: As many microreactors or micromixers are switched to parallel operation until the desired production performance is achieved. In practical working, this concept quickly reaches its economic limits... view more... (2003-04-07)
