For the first time, scientists have used Earth-based telescopes to look back in time over 13 billion years to get a clearer picture of one of the least understood epochs in the history of the universe, the Cosmic Dawn. 

In a paper published on aBIOTECH, the authors constructed G protein mutants using CRISPR/cas9 technology and investigated the biological functions of G proteins in growth, development, and symbiotic nodulation in Medicago truncatula.

In this work, an innovative molecular engineering approach for the bonding of carbon quantum dots (CQDs) with the diamine monomer of polyetherimide (PEI) is presented, leading to the integration of high electrical insulation and high thermal conductivity in hybrid dielectrics (PEI-NH₂-CQDs). This work represents the first example of utilizing CQDs in polymer dielectrics to simultaneously improve energy storage performance and thermal conductivity.

Dr. Hye Jin Nam’s team at the Korea Research Institute of Chemical Technology (KRICT), in collaboration with Professors Dong Hyun Jo and Sangsu Bae at Seoul National University College of Medicine, found that autophagy induction via nutrient deprivation or mTOR inhibition markedly enhances the efficiency of HR-based CRISPR–Cas9 gene editing up to threefold.

Realizing the point-of-care tumor markers biodetection with good convenience and high sensitivity possesses great significance for prompting cancer monitoring and screening in biomedical study field. Herein, the quantum dots luminescence and microfluidic biochip with machine vision algorithm-based intelligent biosensing platform have been designed and manufactured for point-of-care tumor markers diagnostics. The employed quantum dots with excellent photoluminescent performance are modified with specific antibody as the optical labeling agents for the designed sandwich structure immunoassay. The corresponding biosensing investigations of the designed biodetection platform illustrate several advantages involving high sensitivity (~ 0.021 ng mL^-1), outstanding accessibility, and great integrability. Moreover, related test results of human-sourced artificial saliva samples demonstrate better detection capabilities compared with commercially utilized rapid test strips. Combining these infusive abilities, our elaborate biosensing platform is expected to exhibit potential applications for the future point-of-care tumor markers diagnostic area.
