Researchers at New York University have developed an innovative way to look at the development of osteoarthritis in the knee joint -- one that relies on the examination of sodium ions in cartilage. Their work, which appears in the Journal of Magnetic Resonance, may provide a non-invasive method to diagnose osteoarthritis in its very early stages.

Fear can make you run, it can make you fight, and it can glue you to the spot. Scientists at the European Molecular Biology Laboratory (EMBL) in Monterotondo, Italy and GlaxoSmithKline in Verona, Italy, have identified not only the part of the brain but the specific type of neurons that determine how mice react to a frightening stimulus.

Researchers have developed an improved coating technique that could strengthen the connection between titanium joint-replacement implants and a patients' own bone. The stronger connection -- created by manipulating signals the body's own cells use to encourage growth -- could allow the implants to last longer.

Much like snowflakes, no two neurons are exactly alike. But it's not the size or shape that sets one neuron apart from another, it's the way it responds to incoming stimuli. Carnegie Mellon University researchers have discovered that this diversity is critical to overall brain function and essential in how neurons process complex stimuli and code information.

After more than a decade of research, Scripps Research Institute scientists have pieced together the structure of a human adenovirus -- the largest complex ever determined at atomic resolution. The new findings about the virus, which causes respiratory, eye, and gastrointestinal infections, may lead to more effective gene therapy and to new anti-viral drugs.

A new study from researchers in Canada and Sweden has shown that biosynthetic corneas can help regenerate and repair damaged eye tissue and improve vision in humans. The results, from an early phase clinical trial with 10 patients, are published in the August 25th, 2010 issue of Science Translational Medicine.

Pathogens make themselves feel at home in the human body, invading cells and living off the plentiful amenities on offer. However, researchers at the Max Planck Institute for Infection Biology, Berlin, together with colleagues at Harvard University, reveal an opposite strategy used to ensure infection success.
