    An analysis of a clinical trial of more than 2,500 people with Type 2 diabetes and kidney disease found that high levels of four biomarkers are strongly predictive for the development of heart and kidney issues.

    A simple blood test may predict the risk of progressive heart and kidney disease in people with Type 2 diabetes and kidney disease, according to new research published today in the American Heart Association’s flagship journal Circulation.

    “High levels of certain biomarkers are indicators of heart and kidney complications and may help predict future risk of disease progression,” said lead author James Januzzi, M.D...

    How Old are you, Biologically? AI can tell your ‘True’ Age by looking at your Chest

    Blood factor can turn back time in the aging brain
    Systemic PF4 enhances adult hippocampal neurogenesis in vivo. a Experimental design of PF4 injection paradigm in young mice. b, c Intravenous (i.v.) PF4 injections for 1 week did not affect neural precursor cell proliferation in the subgranular zone (SGZ; n = 10 mice in saline group; n = 9 mice in PF4 group; counts of one hemisphere), but increased the number of doublecortin+ (DCX+) cells (n = 15 mice per group; counts of one hemisphere). d Experimental design of the double-labeling paradigm with CldU and IdU. e Acute administration of PF4 did not affect neural precursor cell proliferation, including the recruitment of cells from quiescence (n = 20 mice per group). f Running paradigm of PF4 knockout (KO) mice. g Representative images of Ki67+ cells in the S...

    Older Adults who play Digital Puzzle Games have the Same Memory Abilities as People in their 20s, a new study has shown.

    Age plays a part in the type of digital games that are best to stimulate memory

    The study, from the University of York, also found that adults aged 60 and over who play digital puzzle games had a greater ability to ignore irrelevant distractions, but older adults who played strategy games did not show the same improvements in memory or concentration.

    It is known that as humans age, their mental abilities tend to decrease, particularly the ability to remember a number of things at a single time — known as working memory. Working memory is thought to peak between the ages of 20 and 30 before slowly declining as a person gets older.

    Previous research, however, has shown that the way we hold information in the brain changes as we get older, and so the York team looked at whether the ...
