Breakthrough Alzheimer’s blood test could detect disease 15 years before symptoms emerge

By /

A recent trial of 786 people – conducted by Dr. Nicholas Ashton at the University of Gothenburg in Sweden and colleagues – found the new test to be as accurate at detecting the signs of Alzheimer’s as painful lumbar punctures, and better than a range of other tests currently being worked on. Experts say it could pave the way for national screening programs for people 50 and over, and that current treatments could work better with the cases picked up earlier.

Indigenous effort in Bangladesh helps reverse endangered fish’s slide to extinction

By /

Unchecked logging and quarrying of rocks from streambeds in Bangladesh’s Chittagong Hill Tracts led to springs drying up and populations of putitor mahseer fish, an endangered species, disappearing. A project launched in 2016 and backed by USAID and the UNDP is working with Indigenous communities to reverse this decline.
Now, as a result of these efforts, areas where forests have been conserved have seen the flow of springs stabilize and fish populations revive.
