    Monash University, Australia scientists have discovered an enzyme that is key to why exercise improves our health. Importantly this discovery has opened up the possibility of drugs to promote this enzyme’s activity, protecting against the consequences of aging on metabolic health, including type 2 diabetes.

    The proportion of people worldwide over 60 years old will double in the next three decades and by 2031, more than six million Australians will be over 65 years old. The incidence of type 2 diabetes increases with age so this aging population will also result in an increased incidence of the disease globally.

    One of the main reasons for the increased prevalence of type 2 diabetes with age i...

    Size Doesn’t Matter: Rock Composition determines how deadly a Meteorite Impact is

    December 16, 2021, Categories  Astronomy/Space

    The minerology of the rocks that a meteorite hits, rather than the size of the impact, determines how deadly an impact it will have. A new University of Liverpool study has found that the minerology of the rocks that a meteorite hits, rather than the size of the impact, determines how deadly an impact it will have.

    The earth has been bombarded by meteorites throughout its long history. Meteorite impacts generate atmospheric dust and cover the Earth’s surface with debris and have long been considered as a trigger of mass extinctions through Earth’s history.

    A multidisciplinary research team from the University of Liverpool and the Instituto Tecnológico y de Energías Renovables, Tenerife with expertise in palaeontology, asteroid stratigraphy, mineralogy, cloud microphysics and cli...

    For Children, Young Adults with Recurrent AML, Immunotherapy Shows Promise

    December 15, 2021, Categories  Health/Medical, Biology/Biotechnology

    GARA ELIZABETH PHOTOGRAPHYResearchers at Washington University School of Medicine in St. Louis have shown, in a small clinical trial, that pre-activated natural killer cells can help some children and young adults with recurrent AML and few other treatment options. Pictured is Weston Robinett, 3, a patient who received this investigational therapy at Siteman Kids at St. Louis Children’s Hospital and Washington University School of Medicine. He remains in remission more than two years after treatment.

    Natural killer cells could help young patients with few treatment options. An immunotherapy harnessing the immune system’s “natural killer” cells has proven effective in treating acute myeloid leukemia (AML) in some adults whose cancers return...
