Artificial Cervical Disc Replacement Offered for Neck and Arm Pain Problems
Rush University Medical Center is one of the few sites in the country selected to participate in a clinical trial for the Artificial Cervical (neck) Disc, the latest technology in the field.   view more (2005-09-27)

'Achilles' heel' of the herpes virus possibly found
It's one of the most common viruses in America, and one that causes the most guilt and shame. It can get inside almost any kind of human cell, reproduce in vast numbers, and linger for years in the body, causing everything from recurrent genital blisters to sores around the mouth. Its complications can kill, and it may increase susceptibility to... view more... (2005-07-25)

Novel virus entry mechanism could lead to new drugs against poxviruses
Research published in the Proceedings of the National Academy of Sciences on 11 April describes how the Imperial College London team discovered the mechanism allowing Vaccinia virus to shed its outer lipid membrane and enter cells. The mechanism is unique in virology and paves the way for development of new antiviral drugs.   view more (2006-04-12)

Physicists persevere in quest for inexhaustible energy source

Combining PET and CT scans makes cancer treatment more accurate
Doctors have discovered that combining images derived from positron emission tomography and computed tomography in the planning and delivery of radiation treatment for patients with head and neck cancer leads to more accurate delivery of the radiation dose and an increased chance for survival.   view more (2006-05-02)

Scientists identify molecular structure of key viral protein

Dartmouth researchers find that arsenic triggers unique mechanism in rare leukemia
Dartmouth Medical School (DMS) researchers have identified a new way that arsenite, a form of arsenic, acts in treating a rare cancer known as APL, or acute promyelocytic leukemia. Their study is published in the Jan. 3 issue of the Journal of the National Cancer Institute.   view more (2007-01-09)

Researchers discover how compounds prevent viruses from entering cells
Compounds called defensins-known to prevent viruses from entering cells-appear to do so by preventing the virus from merging to cells' outer membrane.   view more (2005-09-16)

Astrophysicists find fractal image of Sun's 'Storm Season' imprinted on Solar Wind
Plasma astrophysicists at the University of Warwick have found that key information about the Sun's 'storm season' is being broadcast across the solar system in a fractal snapshot imprinted in the solar wind.   view more (2007-05-29)

Z machine melts diamond to puddle
Sandia's Z machine, by creating pressures more than 10 million times that of the atmosphere at sea level, has turned a diamond sheet into a pool of liquid.   view more (2006-11-06)

Tissue regeneration operates differently than expected
Scientists from the Max Planck Institute for Heart and Lung Research in Bad Nauheim, Germany, in co-operation with colleagues from Martin Luther University in Halle-Wittenberg, have now shown that skeletal muscle tissue can fuse with adult stem cells, via a mechanism based on the participation of mediators which are generally involved in immune... view more...
