Published DNA chips as storage media of the future: What challenges need to be overcome


In the form of DNA, nature shows how data can be stored in a space-saving and long-term manner. Bioinformatics specialists are developing DNA chips for computer technology. Researchers show how a combination of molecular biology, nanotechnology, novel polymers, electronics and automation, coupled with systematic development, could make DNA data storage useful for everyday use possible in a few years.
Published Towards better batteries and fuel cells with dispersibility estimation for carbon electrode slurries


Carbon slurries, which consist of a suspension of carbon particles in a solvent, are used to mass-produce battery electrodes. However, there are no adequate methods to evaluate whether the particles are uniformly dispersed in the slurry during the manufacturing process. In a recent study, researchers used an innovative approach, combining viscosity and electrochemical impedance measurements, to accurately assess the dispersibility of slurries, opening doors to enhanced electric vehicles and fuel cell batteries.
Published New approach to nongenetic T-cell-based immunotherapy


Immunotherapies for cancer aim to induce the immune system to combat cancer cells more effectively. A research team has now described a new, modular strategy for T-cell-based immunotherapy that manages to work without complex genetic modifications. Modulation of cell-cell communications through an ingenious regulatory circuit using various small, specially folded DNA molecules (aptamers) causes cancer cells to directly activate their mortal enemies, T cells.
Published Graphene discovery could help generate hydrogen cheaply and sustainably


Researchers have finally solved the long-standing puzzle of why graphene is so much more permeable to protons than expected by theory.

Published Research team developing a nano-sized force sensor and improving high-precision microscopy technology


Recent research in cell biology highlights groundbreaking results. An international team of researchers have recently established a tool they developed to study the mechanics of the cell. The tool can be used to study the inner forces of the cell, for example, the stretching of the nuclear membrane. The microscopic force sensor, only about 0.00002 mm long, is constructed of exotic ingredients such as spider web protein parts, fluorescent proteins from jellyfish, and antibodies from alpaca. In addition, the multidisciplinary team of researchers has developed further the sensitivity of super-resolution microscopy technique.

Bioengineers have developed a generalizable method to address 'off-target' binding, a significant problem in the field of synthetic biology. Taking a cue from nature, the researchers showed they could all but eliminate off-target gene activation by designing weak transcription factors that cooperatively assemble.
Published Researchers design efficient iridium catalyst for hydrogen generation


Proton exchange membrane water electrolyzers converts surplus electric energy into transportable hydrogen energy as a clean energy solution. However, slow oxygen evolution reaction rates and high loading levels of expensive metal oxide catalysts limit its practical feasibility.

Additionally, it shows high catalytic activity and long-term stability in prolonged single cell operation.
Published Nanoscale material offers new way to control fire


High-temperature flames are used to create a wide variety of materials -- but once you start a fire, it can be difficult to control how the flame interacts with the material you are trying to process. Researchers have now developed a technique that utilizes a molecule-thin protective layer to control how the flame's heat interacts with the material -- taming the fire and allowing users to finely tune the characteristics of the processed material.
