Shape-Memory Polymer Could Help Robots Flex their Muscles

When stretched or deformed, shape memory polymers return to their original shapes after heat or light is applied. These materials show great promise for soft robotics, smart biomedical devices and deployable space structures, but until now they haven’t been able to store enough energy. Now, researchers reporting in ACS Central Science have developed a shape memory polymer that stores almost six times more energy than previous versions.

Ambivalent Results: Are Biodegradables the Better Plastic?

The idea of biodegradable plastics sounds good at first. However, very little is known about how they are degraded in the soil and how this is influenced by climate change. In two recent studies, soil ecologists at the Helmholtz Centre for Environmental Research (UFZ) have shown which microbial community is responsible for degradation, what role the climate plays in this process, and why biodegradable plastics could still be problematic.

Library of the Human Proteome

Researchers led by the Technical University of Munich (TUM) report on the synthesis of a library of more than 330,000 reference peptides representing essentially all canonical proteins of the human proteome. This research is a major milestone in the ProteomeTools project which aims at translating human proteome information into new molecular and digital tools with the potential for use in drug discovery, personalized medicine and life science research.
