Extreme fast charging capability in lithium-ion batteries      (via sciencedaily.com) 

Lithium-ion batteries dominate among energy storage devices and are the battery of choice for the electric vehicle industry. Improving battery performance is a constant impetus to current research in this field. Towards this end, a group of researchers has synthesized a lithium borate-type aqueous polyelectrolyte binder for graphite anodes. Their new binder helped improve Li-ion diffusion and lower impedance compared to conventional batteries.

Researchers provide proof of the helical coiling of condensed chromosomes      (via sciencedaily.com)     Original source 

In early cytological studies chromatids of metaphase chromosomes were suggested to coil into a spiral called chromonema. This assumption was recently supported by chromosomce conformation capture sequencing. Still, the direct visualization of the coiled chromonema confirming the helical model was lacking. Now, an international research team provides the direct proof of the helical coiling of condensed chromatids via super-resolution microscopy of specifically labelled chromonema regions.

New study unveils epigenetic 'traffic lights' controlling stop and go for gene activity      (via sciencedaily.com) 

A major new study reveals a 'traffic light' mechanism controlling genetic activity within cells -- a system which could potentially be targeted by cancer drugs already in development. The research describes how 'epigenetic' changes to the structure of DNA can act as a stop-go signal in determining whether a gene should be read. Unlike our genetic make-up, which is well understood, the world of epigenetics is still largely unexplored and referred to as the 'dark matter' of the genome.

Ancient proteins offer new clues about origin of life on Earth      (via sciencedaily.com)     Original source 

By simulating early Earth conditions in the lab, researchers have found that without specific amino acids, ancient proteins would not have known how to evolve into everything alive on the planet today -- including plants, animals, and humans.

Corralling ions improves viability of next generation solar cells      (via sciencedaily.com) 

Researchers have discovered that channeling ions into defined pathways in perovskite materials improves the stability and operational performance of perovskite solar cells. The finding paves the way for a new generation of lighter, more flexible, and more efficient solar cell technologies suitable for practical use.

Cells avoid multitasking      (via sciencedaily.com) 

Textbooks will tell you that in dividing cells, production of new DNA peaks during the S-phase, while production of other macromolecules, such as proteins, lipids, and polysaccharides, continues at more or less the same level. Molecular biologists have now discovered that this is not true: protein synthesis shows two peaks and lipid synthesis peaks once.

Successful cure of HIV infection after stem cell transplantation, study suggests      (via sciencedaily.com) 

Haematopoietic stem cell transplantation for the treatment of severe blood cancers is the only medical intervention that has cured two people living with HIV in the past. An international group of physicians and researchers has now identified another case in which HIV infection has been shown to be cured in the same way. The successful healing process of this third patient was for the first time characterized in great detail virologically and immunologically over a time span of ten years.

The achilles heel of the influenza virus: Ubiquitin protein may be an approach for future medicines      (via sciencedaily.com)     Original source 

Influenza viruses are becoming increasingly resilient to medicines. For this reason, new active ingredients are needed. Important findings in this regard have been provided: for the virus to proliferate, the polymerase of the influenza A virus has to be modified many times through enzymes in the host cells. The team of researchers was able to produce a comprehensive map of types of modification. Medicines directed against the enzymes woud be resilient to rapid mutations in the virus, thus offering great potential for the future.

Heterostructures support predictions of counterpropagating charged edge modes at the v=2/3 fractional quantum Hall state      (via sciencedaily.com)     Original source 

Researchers have tested models of edge conduction with a device built on top of the semiconductor heterostructure which consists of gold gates that come close together. Voltage is applied on the gates to direct the edge states through the middle of the point contact, where they are close enough that quantum tunneling can occur between the edge states on opposite sides the sample. Changes in the electrical current flowing through the device are used to test the theorists' predictions.
