[…]

  • Tissue-engineered human pancreatic cells successfully treat diabetic mice
    on May 8, 2018 at 3:17 pm

    Researchers tissue-engineered human pancreatic islets in a laboratory that develop a circulatory system, secrete hormones like insulin and successfully treat sudden-onset type 1 diabetes in transplanted mice. The scientists use a new bioengineering process they developed called a self-condensation cell culture. The technology helps nudge medical science closer to one day growing human organ tissues from a person's own cells for regenerative therapy, say study investigators. […]

  • Spawing better ways to combat crop-killing fungus
    on April 26, 2018 at 4:59 pm

    About 21 million years ago, a fungus that causes a devastating disease in rice first became harmful to the food that nourishes roughly half the world's population, according to an international study. The findings may help lead to different ways to fight or prevent crop and plant diseases, such as new fungicides and more effective quarantines. […]

  • CRISPR/Cas9 silences gene associated with high cholesterol
    on April 26, 2018 at 4:59 pm

    Biomedical engineers have used a CRISPR/Cas9 genetic engineering technique to turn off a gene that regulates cholesterol levels in adult mice, leading to reduced blood cholesterol levels and gene repression lasting for six months after a single treatment. This marks the first time researchers have delivered CRISPR/Cas9 repressors for targeted therapeutic gene silencing in adult animal models. […]

  • Protect forest elephants to conserve ecosystems, not DNA
    on April 25, 2018 at 4:02 pm

    New research has found that forest elephant populations across Central Africa are genetically quite similar to one another. Conserving this critically endangered species across its range is crucial to preserving local plant diversity in Central and West African Afrotropical forests -- meaning conservationists could save many species by protecting one. […]

  • Mice 'eavesdrop' on rats' tear signal
    on March 29, 2018 at 6:10 pm

    Tears might not seem to have an odor. But studies have shown that proteins in tears act as pheromonal cues. For example, the tear glands of male mice produce a protein that makes females more receptive to sex. New research finds that rat tears contain proteins with similar functions. Mice can pick up on the rats' tear proteins, too, apparently tipping them off that predators are around. […]
