Previously unknown immune cell may help those with Crohn's and colitis
The tonsils and lymphoid tissues in the intestinal tract that help protect the body from external pathogens are the home base of a rare immune cell newly identified by researchers at Washington University School of Medicine in St. Louis. view more (2008-11-04)
Laser-optical mine detection needle will facilitate mine clearing
The "laser-optical mine detection needle" is intended to facilitate the removal of land mines for humanitarian reasons. The working group of Professor Dr. Wolfgang Schade at the Institute of Physics und Physical Technologies at the Technical University of Clausthal intends to exhibit a "laser-optical mine detection needle" at... view more...

Making waves in cancer detection
We`re all familiar with X-rays being used to look inside our bodies. But according to physicists, medical imaging in the future is likely to be based on an as yet unused type of radiation known as terahertz radiation. view more (2002-07-23)
Head and neck cancer vaccine targets proteins to create immune response
Most attempts to create therapeutic cancer vaccines are based on custom-made approaches that use a patient's own tumor cells to generate a strong immune response against cancer. However, developing these kinds of personalized vaccines is time-consuming, expensive and often impractical. view more (2007-04-18)
NYU Langone Medical Center researchers identify key gene in deadly inflammatory breast cancer
Aggressive, deadly and often misdiagnosed, inflammatory breast cancer (IBC) is the most lethal form of primary breast cancer, often striking women in their prime and causing death within 18 to 24 months. view more (2009-06-15)
Infrared Echoes Give NASA's Spitzer a Supernova Flashback
Hot spots near the shattered remains of an exploded star are echoing the blast's first moments, say scientists using data from NASA's Spitzer Space Telescope. view more (2008-10-02)
Disorder may be in order for 'spintronic' devices
Physicists at JILA are using ultrashort pulses of laser light to reveal precisely why some electrons, like ballet dancers, hold their spin positions better than others—work that may help improve spintronic devices, which exploit the magnetism or "spin" of electrons in addition to or instead of their charge. One thing spinning... view more... (2007-02-16)
Laser Destroys Atherosclerosis Plaques
Russian medical professionals are trying to fight atherosclerosis by means of low-intensity infrared laser therapy. The relevant clinical tests are demonstrating successful results. Atherosclerosis vascular diseases have become the principal cause of disability or death for the population of industrially developed countries. Atherosclerosis... view more... (2004-05-07)
Ecologists spawn new use for PIT tags
Fishing for a way to assess mixing behavior in treatment tanks for radioactive waste, ecologists at Pacific Northwest National Laboratory came up with an innovative use of radio frequency technology previously used to track migrating fish. view more (2005-10-06)
Multiple sclerosis damage found in 'normal' brain tissue
The effects of multiple sclerosis (MS) extend beyond visibly affected areas into large portions of the brain that outwardly appear normal, according to a study appearing in the September issue of Radiology. view more (2006-08-29)
A chemotherapy drug packs a one-two punch
Cancer can be wily, and those who treat the disease have amassed a wide array of weapons with which to fight it and kill tumors. view more (2007-02-21)
Lasers spark new paths in radio-isotope transmutation - Scientific breakthrough in the transmutation of isotopes
Collaboration between the European Commission's Joint Research Centre (JRC) DG, the University of Jena (Germany), the University of Strathclyde (UK), Imperial College (UK), and the Rutherford Appleton Laboratory (UK) has led to the transmutation of long-lived radioactive iodine-129 into short-lived iodine-128 using very high intensity laser... view more...

University of Pittsburgh discovers genetic 'shut down' trigger in healthy immune cells
A fundamental genetic mechanism that shuts down an important gene in healthy immune system cells has been discovered that could one day lead to new therapies against infections, leukemia and other cancers. view more (2007-05-10)
Long-distance record -- 'Quantum keys' sent 200 kilometers
Particles of light serving as "quantum keys"-the latest in encryption technology-have been sent over a record-setting 200-kilometer fiber-optic link by researchers from the National Institute of Standards and Technology (NIST), NTT Corp. in Japan, and Stanford University. view more (2007-06-04)

POLYMUN Scientific, together with 20 other companies, has been selected from 300 submissions to present its innovative pharmaceutical projects at the prestigious "Taste of Entrepreneurship: Financing and Research" symposium in Louvain-La-Neuve, Belgium, Nov. 19 and 20, 2002. POLYMUN will present its pharmaceutical projects in view of the newest... view more... (2002-11-15)
The little beam that could
Scientists at Los Alamos National Laboratory, in collaboration with researchers from the University of Nevada, Reno, Ludwig-Maximilian-University in Germany, and the Max-Planck-Institute for Quantum Optics in Germany, have developed a new method for using a laser beam to accelerate ions. view more (2006-02-01)
White blood cells of cancer-resistant mice overwhelm natural defenses of cancer cells
The discoverers of the unique mouse line that is resistant to cancer have begun to pin down how the process works and found that white blood cells in these mice overwhelm normal defenses of cancer cells. view more (2006-11-01)
Seeing previously invisible molecules for the first time
A team of Harvard chemists led by X. Sunney Xie has developed a new microscopic technique for seeing, in color, molecules with undetectable fluorescence. view more (2009-10-26)
Models of eel cells suggest electrifying possibilities
Engineers long have known that great ideas can be lifted from Mother Nature, but a new paper by researchers at Yale University and the National Institute of Standards and Technology (NIST) takes it to a cellular level. view more (2008-10-03)
Kidney donor age linked to aortic siffening
Transplantation of kidneys from older donors is followed by increased stiffening of the recipient's aorta-which may help to explain the higher rates of cardiovascular disease and death in patients receiving kidneys from "expanded criteria" donors, reports a study in the April Journal of the American Society of Nephrology. view more (2008-02-22)
