Surprising new mechanism of heat shock response identified in yeast cells

How cells respond in the face of stress is a critical component of maintaining homeostasis and preventing disease, but its mechanisms are poorly understood. New research out of the University of Chicago has fit together another piece of the puzzle by identifying a key protein, Sis1, involved in the rapid activation of the heat shock response, which allows cells to respond in the face of temperature changes that can lead to misfolded proteins. This has implications for conditions where changes in the stress response have been implicated in the pathology of the disease.The results were published on Jan. 4 in the Journal of Cell Biology.

Chemists develop polymer cathodes for ultrafast batteries

In the face of the surging demand for lithium-ion batteries and limited lithium reserves, scientists are searching for alternatives to the lithium technology. Russian researchers from Skoltech, D. Mendeleev University, and the Institute of Problems of Chemical Physics of RAS have synthesized and tested new polymer-based cathode materials for lithium dual-ion batteries. The tests showed that the new cathodes withstand up to 25,000 operating cycles and charge in a matter of seconds, thus outperforming lithium-ion batteries. The cathodes can also be used to produce less expensive potassium dual-ion batteries. The research was published in the journal Energy Technology.

What stops flows in glassy materials?

Glasses have a liquid-like disordered structure but solid-like mechanical properties. This leads to one of the central mysteries of glasses: Why don't they flow like liquids? This question is so important that it was selected by the journal Science in 2005 as one of 125 key, unanswered scientific questions, and one of 11 unsolved important physical issues.

Darkness from light

Microresonators are small glass structures in which light can circulate and build up in intensity. Due to material imperfections, some amount of light is reflected backwards, which is disturbing their function. Researchers have now demonstrated a method for suppressing these unwanted back reflections. Their findings can help improve a multitude of microresonator-based applications from measurement technology such as sensors used for example in drones, to optical information processing in fibre networks and computers. The results of the team spanning the Max Planck Institute for the Science of Light (Germany), Imperial College London, and the National Physical Laboratory (UK) are published now in the Nature-family journal Light: Science and Applications.

Promoting axon regeneration in the zebrafish spinal cord

After an injury to the spinal cord, patients often remain paralyzed because damaged nerve tracts do not regrow due to the formation of scar tissue. Scientists from the Max Planck Institute for the Science of Light in Erlangen, together with colleagues from Dresden and Athens, have now been able to identify important cells and molecules in the scar, using zebrafishes as a model organism.

Dopant-free, humidity-stable organic layers give perovskite solar cells 21% efficiency

Durable, high-performing perovskite solar cells also require durable, high-performing charge-transporting layers. Scientists have developed the first organic hole transporter that does not need a dopant to attain high charge mobility and stability. According to the study published in the journal Angewandte Chemie, this novel hole-transporting layer outperforms reference materials and protects the perovskite organic cell from air humidity.

Better diet and glucose uptake in the brain lead to longer life in fruit flies

Researchers from Tokyo Metropolitan University have discovered that fruit flies with genetic modifications to enhance glucose uptake have significantly longer lifespans. Looking at the brain cells of aging flies, they found that better glucose uptake compensates for age-related deterioration in motor functions, and led to longer life. The effect was more pronounced when coupled with dietary restrictions. This suggests healthier eating plus improved glucose uptake in the brain might lead to enhanced lifespans.
