Do some diabetes drugs reduce the risk of Alzheimer’s? Posted: 11 Aug 2021 02:52 PM PDT People taking certain drugs to lower blood sugar for type 2 diabetes had less amyloid in the brain, a biomarker of Alzheimer's disease, when compared to both people with type 2 diabetes not taking the drugs and people without diabetes. The new study also found people taking these drugs, called dipeptidyl peptidase-4 inhibitors, showed slower cognitive decline than people in the other two groups. |

The study showed key differences in the ways that individuals with ASD processed or reacted to stimuli compared to those who were more neurotypical, with implications for future research across age range, intelligence and setting. |
Treating the ‘root’ cause of baldness with a dissolvable microneedle patch Posted: 11 Aug 2021 01:28 PM PDT Although some people say that baldness is the 'new sexy,' for those losing their hair, it can be distressing. An array of over-the-counter remedies are available, but most of them don't focus on the primary causes: oxidative stress and insufficient circulation. Now, researchers have designed a preliminary microneedle patch containing cerium nanoparticles to combat both problems, regrowing hair in a mouse model faster than a leading treatment. |
