Study uncovers how harmful RNA clumps form — and a way to dissolve them

2025-07-07
BUFFALO, N.Y. — Look inside a brain cell with Huntington’s disease or ALS and you are likely to find RNA clumped together. These solid-like clusters, thought to be irreversible, can act as sponges that soak up surrounding proteins key for brain health, contributing to neurological disorders.  How these harmful RNA clusters form in the first place has remained an open question. Now, University at Buffalo researchers have not only uncovered that tiny droplets of protein and nucleic acids in cells contribute to the formation of RNA clusters but also demonstrated a way to prevent and disassemble ...

At the computer for the lecture or in the lecture hall? It depends!

2025-07-07
During the coronavirus pandemic, german universities had to act quickly: Lectures and seminars had to be offered online via Zoom. After the pandemic-related lockdowns, many lecturers introduced synchronous hybrid teaching/learning settings. These are courses in which students can take part either on site in the seminar room or online at the same time. Students are therefore faced with the decision every session as to whether they want to take part in the course online or on site. Three researchers from the Professorship of Adult Education/Continuing Education at the Institute of Education at Julius-Maximilians-Universität Würzburg (JMU) have investigated the factors ...
