In preeclampsia, researchers identify proteins that cause blood vessel damage
Proteins released by the placenta may damage blood vessels in women with preeclampsia (PE), according to an abstract presented by Yale School of Medicine researchers at the Society for Gynecologic Investigation Conference March 17 in Reno, Nevada. view more (2007-03-19)
Microscopic 'beads' could help create 'designer' immune cells that ignore transplanted organs
The future of organ transplantation could include microscopic beads that create "designer" immune cells to help patients tolerate their new organ, Medical College of Georgia researchers say. view more (2009-07-07)
Cell phones using lens-free imaging promise to improve health monitoring
Cell phones have already revolutionized the way people around the world communicate and do business. Thanks to advances being made at UCLA, they are about to do the same thing for medicine. view more (2008-12-23)
Biodegradable polymers show promise for improving treatment of acute inflammatory diseases
A family of biodegradable polymers called polyketals and their derivatives may improve treatment for such inflammatory illnesses as acute lung injury, acute liver failure and inflammatory bowel disease by delivering drugs, proteins and snips of ribonucleic acid to disease locations in the body. view more (2008-08-21)
Tiny particles can deliver antioxidant enzyme to injured heart cells
Researchers at Emory University and the Georgia Institute of Technology have developed microscopic polymer beads that can deliver an antioxidant enzyme made naturally by the body into the heart. view more (2009-11-16)
New 'self-exploding' microcapsules could take sting out of drug delivery
Belgian chemists have developed "self-exploding" microcapsules that could one day precisely release drugs and vaccines inside the human body weeks or even months after injection. view more (2006-01-04)
Potential new way of treating inflammatory diseases identified
Scientists have shown for the first time that platelets, the cells needed for blood clotting, help white blood cells called neutrophils fight inflammation. view more (2007-09-14)
Scientists ask whether microscaffolding can help stem cells rebuild brain after stroke damage
Inserting tiny scaffolding into the brain could dramatically reduce damage caused by strokes the UK National Stem Cell Network Annual Science Meeting will hear today (10 April). view more (2008-04-10)
HIV conquers immune system faster than previously realized
New research into the earliest events occurring immediately upon infection with HIV-I shows that the virus deals a stunning blow to the immune system earlier than was previously understood. view more (2008-07-21)
Hybrid composite for root canal treatment
Unrelenting toothache means a visit to the dentist is inevitable, and if the tooth decay is really bad root canal treatment is often the only option. view more (2009-11-05)
Children's National researchers develop novel anti-tumor vaccine
A novel anti-tumor vaccine for neuroblastoma and melanoma developed by scientists and clinicians at Children's National Medical Center in collaboration with investigators from the University of Iowa is showing significant impact on tumor growth in mice. view more (2008-10-03)
Wetter report: New approach to testing surface adhesion
With a nod to one of nature's best surface chemists—an obscure desert beetle—polymer scientists at the National Institute of Standards and Technology (NIST) have devised a convenient way to construct test surfaces with a variable affinity for water, so that the same surface can range from superhydrophilic to superhydrophobic, and... view more...

New DNA-based technique for assembly of nano- and micro-sized particles
Scientists at the U.S. Department of Energy's Brookhaven National Laboratory have developed a new method for controlling the self-assembly of nanometer and micrometer-sized particles. view more (2007-09-13)
Discovery offers potential new pancreatic cancer treatment
Tiny particles that can carry drugs and target cancer cells may offer treatment hope for those suffering with pancreatic cancer. New research to be presented in November at the American Association of Pharmaceutical Scientists (AAPS) Annual Meeting in Los Angeles reveals that tumor-penetrating microparticles (TPM) have been specifically designed... view more...

Reversible Microlenses to Speed Chemical Detection
The microlenses make use of the antibody-antigen binding, the same process used by the human immune system, to detect biological or chemical agents. view more (2006-02-14)
Novel 3-D cell culture model shows selective tumor uptake of nanoparticles
A nanoparticle drug delivery system designed for brain tumor therapy has shown promising tumor cell selectivity in a novel cell culture model devised by University of Nottingham scientists. view more (2007-08-23)
MIT sculpts 3-D particles with light
MIT engineers have used ultraviolet light to sculpt three-dimensional microparticles that could have many applications in medical diagnostics and tissue engineering. view more (2007-12-04)
Tiny capsules deliver
A tiny particle syringe composed of polymer layers and nanoparticles may provide drug delivery that targets diseased cells without harming the rest of the body, according to a team of chemical engineers. This delivery system could be robust and flexible enough to deliver a variety of substances. view more (2009-01-13)
Magnet lab researcher exploring science behind commercial applications of liquid helium
In a letter published in a recent issue of Nature Physics, Van Sciver wrote that when superfluid helium flows toward and then around a relatively large object, say the size of a small stone, it has a tendency to create whirlpools not just in the back, as would be expected, but also in the front. view more (2005-12-12)
Ancient geologic escape hatches mistaken for tube worms
Tubeworms have been around for millions of years and the fossil record is rich with their distinctive imprints. But a discovery made by U of C scientists found that what previous researchers had labeled as tubeworms in a formation near Denver, Colorado, are actually 70 million-year-old escape hatches for methane. view more (2009-02-05)
