Medical Xpress / Underlying cause of Gulf War illness confirmed

Dysfunctional mitochondria, organelles that serve as cellular power generators, appear to cause the symptoms of Gulf War illness (GWI) among tens of thousands of veterans of the Persian Gulf War, UT Southwestern Medical Center ...

Medical Xpress / Macrophages can act like neurons for faster muscle injury repair, study finds

At the cellular level, the mechanics of how muscle tissue repair occurs gets complicated. There are significant differences between, say, tearing a muscle in a sports injury versus muscle tissue wasting away from diseases ...

Medical Xpress / Reducing inflammation may protect against early age-related macular degeneration-like vision loss

University of Minnesota Medical School researchers have shown that reducing chronic inflammation can significantly protect against age-related macular degeneration (AMD)-like pathology in preclinical models. The findings ...

Phys.org / Reed leafhopper's diverse microbes fuel its rise as a major crop pest

The reed leafhopper (Pentastiridius leporinus) was originally a specialist, limited exclusively to reed grass as a food source. Within a few years, however, it developed into a dangerous pest that attacks not only reed grass ...
