Induced-fit adsorbent for acetylene
We often say that a substrate fits into its enzyme like a key in a lock, but this metaphor is imperfect. Substrate binding can also change the lock (the structure of the enzyme) to induce a perfect fit. In the journal Angewandte Chemie, an internatio.....»»
Important step towards accurate use of stem cell–based disease models
Induced pluripotent stem cells offer great therapeutic potential and are a valuable tool for understanding how different diseases develop. New research shows that such stem cell lines should be regularly screened for genetic mutations to ensure the a.....»»

Taiwan MCU makers divided over sales strategies for post-pandemic China
Taiwan's MCU suppliers are recalibrating sales strategies in the Chinese market, which is set to rebound in 2023 following three years of COVID-induced weak consumer demand, according to industry sources......»»
A tool to prevent deaths due to female underrepresentation in clinical trials
Women are often underrepresented in cardiac clinical trials—yet they are at least at equally high risk of death due to cardiovascular disease, and at higher risk of developing drug-induced heart complications compared to men. Clinical trials of med.....»»
Research team establishes cell lines to improve iPSC research
Induced Pluripotent Stem Cell (iPSC) lines have become essential for determining the underlying genetic drivers of human disease. Genomes of iPSCs can be easily edited using the bacteria-based CRISPR/Cas9 technology to introduce or correct disease-as.....»»
