Disrupting Enzyme To Tackle Alzheimer’s Disease

By Rideeta Raquib ’19 From histone modifications to DNA alterations, epigenetic processes play a major role in various physiological systems. Histones are proteins in eukaryotic cells that package DNA strands into nucleosomes. Gene regulation processes include histone acetylation, whereby an acetyl group is transferred from one molecule to another. This eventually removes the positive charge…

Researchers Develop Low-Power Assistive Stairs

By Anna Tarasova ’19 Many elderly and mobility-impaired individuals are unable or tend to be unwilling to use stairs. While assistive technologies exist, they are frequently costly and unsustainable. The principle of energy recycling has been previously applied to walking assistance mechanisms that take advantage of the continuous braking and propelling of the legs. However,…
