Skin cancers linked with up to a 92% reduced risk of Alzheimer’s disease

Public Release: 19-Apr-2018   Wiley Previous studies have demonstrated a decreased risk of Alzheimer’s disease (AD) in individuals with various cancers, including non-melanoma skin cancers (including squamous cell cancers and basal cell cancers). A new Journal of the European Academy of Dermatology & Venereology study finds that this inverse relationship also holds true for malignant…

Rats sniff out TB in children

Public Release: 9-Apr-2018   Research shows that rats can detect tuberculosis in children with higher accuracy than standard microscopy tests Springer Rats are able to detect whether a child has tuberculosis (TB), and are much more successful at doing this than a commonly used basic microscopy test.
