Researchers have developed a jelly-like material that can withstand the equivalent of an elephant standing on it, and completely recover to its original shape, even though it’s 80% water.

The soft-yet-strong material, developed by a team at the University of Cambridge, looks and feels like a squishy jelly, but acts like an ultra-hard, shatterproof glass when compressed, despite its high water content.

The non-water portion of the material is a network of polymers held together by reversible on/off interactions that control the material’s mechanical properties. This is the first time that such significant resistance to compression has been incorporated into a soft material.

The ‘super jelly’ could be used for a wide range of potential applications, including soft robotics,...

Sofia Bergman, Swedish Institute of Space Physics (IRF) and Umeå University, will defend her doctoral thesis on low-energy ions around comet 67P/Churyumov-Gerasimenko on 26 November. Observing low energy ions is notoriously difficult because their properties are affected greatly by the spacecraft which observes them. Sofia has developed new methods to do this. Using her work, scientists can study low-energy ions around comets and in a variety of other places in the solar system.

Comets have an environment of plasma which contains a large number of ions with low energies...

Just three minutes of exposure to deep red light once a week, when delivered in the morning, can significantly improve declining eyesight, finds a pioneering new study by UCL researchers.

Published in Scientific Reports, the study builds on the team’s previous work*, which showed daily three-minute exposure to longwave deep red light ‘switched on’ energy producing mitochondria cells in the human retina, helping boost naturally declining vision.

For this latest study, scientists wanted to establish what effect a single three-minute exposure would have, while also using much lower energy levels than their previous studies...

Water-In-Polymer Salt Electrolyte for Slow Self-discharge in Organic Batteries. Safe, cheap and sustainable technology for energy storage has been developed at the Laboratory of Organic Electronics, Linköping University. It is based on two major breakthroughs: the manufacture of wood-based electrodes in rolled form, and a new type of water-based electrolyte. The result has been published in the scientific journal Advanced Energy and Sustainability Research...
