Circular dichroism in the deep ultraviolet
In nature, certain molecules with the same chemical composition, can exist in two different shapes that are mirrors images of each other, much like our hands. This property is known as "chirality" and molecules with different chirality are called enantiomers. Enantiomers can exhibit entirely ...
Biomimetic strategy leads to strong, recyclable rubber
Inspired by nature, Chinese scientists have produced a synthetic analogue to vulcanized natural rubber. Their material is just as tough and durable as the original. In the journal Angewandte Chemie, they reveal the secret to their success: short protein chains attached to the side-chains of the ...
The wonders of graphene are numerous -- it can enable flexible electronic components, enhance solar cell capacity, filter the finest subatomic particles and revolutionize batteries. Now, the "supermaterial" may one day be used to test for amyotrophic lateral sclerosis, or ALS -- a progressive, ...
Milestone on the way to direct imaging of individual biomolecules
A team of scientists at DESY and Universität Hamburg has reached another milestone towards the direct imaging of individual biomolecules: the group led by Jochen Küpper from the Center for Free-Electron Laser Science developed a new experimental technique which enables the separation of different ...
Researchers have developed a method that makes it possible to measure the activation of receptors in a very short time
Hormones and other neurotransmitters, but also drugs, act upon receptors. “Their active substances bind to the receptors and modify the three-dimensional receptor arrangement regulating the downstream signal pathways,” says Hannes Schihada from the Institute for Pharmacology and Toxicology at the ...
Researchers establish a benchmark for accurate determination of internal dimensions within individual molecules
A worldwide study involving 20 laboratories has established and standardized a method to measure exact distances within individual biomolecules, down to the scale of one millionth of the width of a human hair. The new method represents a major improvement of a technology called single-molecule ...
Method giving complete spatiotemporal control and treads DNA lightly
A major obstacle to in-cell genome editing is, well, the cell itself.“Human cells don’t like to take in stuff,” explained UC Santa Barbara’s Norbert Reich, a professor in the Department of Chemistry and Biochemistry. The human cell has evolved a “trash disposal” mechanism that isolates and breaks ...
Proteins that self-assemble into supramolecular complexes
A collaborative research team based in Japan has designed new proteins that can self-assemble into the complex structures underlying biological organisms, laying the groundwork for leading-edge applications in biotechnology. The researchers created and developed the proteins with a specific ...
New research has demonstrated how the nano-architecture of a silkworm's fiber causes "Anderson localization of light," a discovery that could lead to various innovations and a better understanding of light transport and heat transfer. The discovery also could help create synthetic materials and ...
We may soon have detailed images of life’s complex machineries in atomic resolution. The Nobel Prize in Chemistry 2017 is awarded to Jacques Dubochet, Joachim Frank and Richard Henderson for the development of cryo-electron microscopy, which both simplifies and improves the imaging of ...
q&more – the networking platform for quality excellence in lab and process
