    Pathways that Extend Lifespan by 500% identified

    January 10, 2020, Categories  Health/Medical, Biology/Biotechnology

    Jarod A. Rollins of the MDI Biological Laboratory in Bar Harbor, Maine, is a lead author of a recent scientific paper that identifies synergistic cellular pathways for longevity that amplify lifespan fivefold in C. elegans, a nematode worm used as a model in aging research. The increase in lifespan would be the equivalent of a human living for 400 or 500 years. The discovery of the synergistic effect opens the door to new, more effective anti-aging therapies.

    Smart Algorithm finds possible future treatment for Childhood Cancer

    Us Integrative discovery of treatments for high-risk neuroblastoma. Nature Communications, 2020; 11 (1) DOI: 10.1038/s41467-019-13817-8

    Using a computer algorithm, scientists at Uppsala University have identified a promising new treatment for neuroblastoma. This form of cancer in children, which occurs in specialised nerve cells in the sympathetic nervous system, may be life-threatening. In the long term the discovery, described in the latest issue of the scientific journal Nature Communications, may result in a new form of treatment for children in whom the disease is severe or at an advanced stage.

    The new treatment is based on activating a receptor protein, CNR2 (cannabinoid receptor 2), in the nervous system...

    A new study finds that the pleasure center of the brain and the brain’s biological clock are linked, and that high-calorie foods – which bring pleasure – disrupt normal feeding schedules, resulting in overconsumption.

    During the years 1976 through 1980, 15% of U.S. adults were obese. Today, about 40% of adults are obese. Another 33% are overweight.

    Coinciding with this increase in weight are ever-rising rates of heart disease, diabetes, cancer and health complications caused by obesity, such as hypertension...

    Step toward ‘Ink’ development for 3D Printing a Bioprosthetic Ovary

    January 7, 2020, Categories  Health/Medical, Biology/Biotechnology

    Findings a huge step forward in fertility preservation and hormone restoration. For the first time, scientists identified and mapped the location of structural proteins in a pig ovary. Ongoing development of an “ink” with these proteins will be used for 3-D printing an artificial (or bio-prosthetic) ovary that could be implanted and allow a woman to have a child...
