Self-learning robots.

Researchers from AMOLF's Soft Robotic Matter group have shown small, autonomous, self-learning robots can adapt easily to changing circumstances. They connected a group of simple robots in a line, after which each individual robot taught itself to move forward as quickly as possible.

The results are available in PNAS: https://www.pnas.org/content/118/21/e2017015118/tab-article-info

Ending childhood respiratory infections.

Human parainfluenza viruses are the leading cause of childhood respiratory infections. There are currently no available vaccines for the most prevalent of these viruses. Research from the University of Wisconsin shows that engineering suitable short chunks of protein can prevent the attachment of human parainfluenza viruses to cells.

The work has recently been published in JACS: https://pubs.acs.org/doi/10.1021/jacs.1c01565

Artificial muscles.

Universidad Carlos III de Madrid researchers offer guidance on the design of magneto-active structural systems that can be applied to stimulate wound healing and artificially replicate muscle tissues. They describe their method as creating an ‘athletic track for cells’.

Two articles on their work have been published recently in Composites Part B: Engineering and International Journal of Solids and Structures: https://doi.org/10.1016/j.compositesb.2021.108796 https://doi.org/10.1016/j.ijsolstr.2020.10.028

Diagnosing prostate cancer with light.

Prostate cancer is the second most common cancer globally in men, but rapid and accurate screening remains a challenge. Researchers from Chernivtsi National University & University of Oulu demonstrate a diagnostic method using polarized light that can quickly analyze prostate tissue samples for signs of cancer.

Why are women under-represented in science?

Women are in the minority in scientific disciplines, but it shouldn’t be that way. What are the barriers that prevent women from gaining equal representation? What solutions should be implemented? How do the challenges vary around the world?

STEMM Global gathered a diverse international panel of Women in Science at the SNAIA 2020 conference to discuss and debate the issues they’ve seen in their careers so far. Joining Anna and Kate from STEMM Global are:
Monica Craciun (University of Exeter)
Yue Wang (University College London)
Silvia Giordani (Dublin City University)
Olga Smolyanskaya (ITMO University)
Madhu Bhaskaran (RMIT University)

Enhanced Raman scattering.

Devices at the single nanometre scale require characterisation at the atomic level. A team at the Japanese Institute for Molecular Science and the Fritz-Haber Institute has demonstrated a huge enhancement of Raman scattering at the atomic point contact of a plasmonic silver tip.

Liquid light.

Researchers at St. Petersburg State University have experimentally observed the formation of a Bose-Einstein condensate in molybdenum diselenide. The condensate contains thousands of exciton polaritons, or ‘liquid light’ quanta, which can be used to carry information in quantum computing applications.

STEMM Global & Engineering Seminars Series (University of Exeter)

Recent advances in microrobotics have demonstrated remarkable locomotive capabilities such as hovering flights, impulsive jumps, and fast running in insect-scale robots. However, most microrobots that are powered by power-dense rigid actuators have not achieved insect-like collision resilience. Meanwhile, the agility of most soft-actuated microrobots remains limited compared to that of rigid-actuated robots.

In this talk, Prof Kevin Chen will present their recent effort in developing a new class of microrobots – ones that are powered by high bandwidth soft actuators and equipped with rigid appendages for effective interactions with environments. Their work demonstrates for the first time that soft aerial robots can achieve agile and robust flight capabilities absent in rigid-powered micro-aerial vehicles, thus showing the potential of a new class of hybrid soft-rigid robots.

Prof. Chen is currently the D. Reid Weedon, Jr. ’41 Career Development Assistant Professor at the Department of Electrical Engineering and Computer Science, Massachusetts Institute of Technology (MIT)
- He received his PhD in Engineering Sciences at Harvard University in 2017 and his bachelor’s degree in Applied and Engineering Physics from Cornell University in 2012.
- His work focuses on developing multifunctional and multimodal insect-scale robots.
- His research interests also include developing high bandwidth and robust soft actuators for microrobot manipulation and locomotion.
- He is a recipient of the best student paper award at the International Conference on Intelligent Robots and Systems (IROS) 2015 and a Harvard Teaching Excellence Award.
- He was named to the “Forbes 30 Under 30” list in the category of Science.

Understanding biology with light.

A team at Aston University has shown how light can be used to assess structures and changes in biological tissues. By looking at changes in the polarisation of light passing through the tissues, maps can be produced that correlate with the tissue structures.

Better batteries.

Solid-state batteries pack a lot of energy into a small space, but their electrodes are not good at keeping in touch with their electrolytes. University of Illinois researchers demonstrate how controlling the atomic alignment of solid materials can improve the electrolyte interface and stability in solid-state batteries.
