    Screen-Printing Method can make Wearable Electronics Less Expensive

    A new study demonstrates that electrodes can be made using just screen printing, creating a stretchable, durable circuit pattern that can be transferred to fabric and worn directly on human skin. Such wearable electronics can be used for health monitoring in hospitals or at home. Current commercial manufacturing of wearable electronics requires expensive processes involving clean rooms. While some use screen printing for parts of the process, this new method relies wholly on screen printing, which can make manufacturing flexible, wearable electronics much easier and less expensive.

    The glittering, serpentine structures that power wearable electronics can be created with the same technology used to print rock concert t-shirts, new research shows.

    Study reveals Obesity-related Trigger that can lead to Diabetes

    January 12, 2023, Categories  Health/Medical, Biology/Biotechnology

    Researchers at Washington University School of Medicine in St. Louis have found that a defect in an enzyme called APT1 interferes with the ability to secrete insulin, contributing to the development of Type 2 diabetes in people who are overweight or obese. In this microscopic image of the surface of an insulin-secreting beta cell from a mouse with diabetes, granules containing insulin are green; granules containing a protein affected by APT1 are red; and the yellow granules are those that release excess insulin due to a defect in APT1.

    Many with elevated insulin levels also have defects in an enzyme key to fatty acid processing...

     PD-associated species nominated by consensus of MaAsLin2 and ANCOM-BC. Analysis included N = 724 biologically independent samples from 490 PD and 234 neurologically healthy control (NHC) subjects. a 257 species (denoted by circles in the plot) were tested in microbiome-wide association study (MWAS) with two statistical methods: MaAsLin2 and ANCOM-BC. The results are shown according to significance (−log10 of the FDR) achieved by MaAslin2 (Y-axis) vs ANCOM-BC (X-axis). Corresponding untransformed FDR values are provided in parentheses on the X and Y axes for easier interpretation. 84 species were nominated as PD-associated, defined by FDR < 0.05 by one method and FDR≤0.1 by the other: 68 achieved FDR < 0.05 by both methods, 10 achieved ANCOM-BC MaAsLin2 FDR < 0.05 by MaAsLin2 and FDR≤0...

    Human-approved Medication Brings Back ‘Lost’ Memories in Mice

    Students sometimes pull an all-nighter to prepare for an exam. However, research has shown that sleep deprivation is bad for your memory. Now, University of Groningen neuroscientist Robbert Havekes discovered that what you learn while being sleep deprived is not necessarily lost, it is just difficult to recall.

    Together with his team, he has found a way to make this “hidden knowledge” accessible again days after studying while sleep-deprived using optogenetic approaches, and the human-approved asthma drug...
