A new study has modeled a crucial first step in the self-assembly of cellular structures such as drug receptors and other protein complexes, and found that the flexibility of the structures has a dramatic impact on how fast two such structures join together.
A team has published pictures at very high atomic resolution of the multi-part protein complex that performs the very first step in the incredibly complex genome-replication dance that occurs when one cell becomes two.
Scientists have been able to reveal for the first time the dynamics of the orbital angular momentum of plasmons. They used a combination of extremely high-quality single crystals of gold, ultrafast laser pulses and an electron microscope.
In work that could help make possible a faster, longer-lasting and lower-energy method of data storage for consumers and businesses, researchers have developed a technique for imaging and studying a promising class of magnetic devices with 10 times more detail than optical microscopes.
Researchers have devised disordered arrangement of the antennas to minimize redundancy between the antennas and enabled each antenna to function independently. As a result, the device can provide 40 times wider bandwidth than existing antennas periodically arranged.
Researchers have succeeded in controlling the growth of organic molecules using a special trick. Molecules that repel each other play a key role in this process: due to their opposing forces, they always keep a certain distance from their neighbours.
To disclose molecular processes behind AuNP growth in protein nanocages, a group of biomolecular engineers used high-resolution crystallography and analyzed the formation of Au nanoclusters in ferritin.
