    Researchers at the University of Georgia’s Regenerative Bioscience Center and their colleagues have found that “natural killer” white blood cells could guard against the cascade of cellular changes that lead to Parkinson’s disease and help stop its progression.

    Natural killer (NK) cells are white blood cells that can kill tumors without being “told” from the body to do so...

    SARS-CoV-2 stability similar to original SARS virus. The virus that causes coronavirus disease 2019 (COVID-19) is stable for several hours to days in aerosols and on surfaces, according to a new study from National Institutes of Health, CDC, UCLA and Princeton University scientists in The New England Journal of Medicine.

    The scientists found that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was detectable in aerosols for up to 3hrs , up to 4hours on copper, up to the24hours on cardboard and up to 2d to 3d on plastic and s...

    Disabling key enzymes overcomes previous limitations to blocking angiogenesis. Scientists at the National Institutes of Health and other institutions have devised a new strategy to stop tumors from developing the new blood vessels they need to grow. Once thought to be extremely promising for the treatment of cancer, blocking molecules that stimulate new blood vessel growth (angiogenesis) has proven ineffective because tumor cells respond by producing more stimulatory molecules. The new strategy involves disabling key enzymes that replenish the molecule that cells need for the reactions that sustain new vessel growth. The research team was led by Brant M. Weinstein, Ph.D...

    ​Chalmers researchers have developed a new material that could be suitable for various medical applications. The 3D printed ‘nose’ above, for example, shows how the material could act as a possible replacement for cartilage.​

    Researchers from Chalmers University of Technology, Sweden, have created a new, rubber-like material with a unique set of properties, which could act as a replacement for human tissue in medical procedures. The material has the potential to make a big difference to many people’s lives. The research was recently published in the highly regarded scientific journal ACS Nano.

    In the development of medical technology products, there is a great demand for new naturalistic materials suitable for integration with the body...
