In a discovery published in the journal Nature, an international team of researchers has described a novel molecular device with exceptional computing prowess. Reminiscent of the plasticity of connections in the human brain, the device can be reconfigured on the fly for different computational tasks by simply changing applied voltages. Furthermore, like nerve cells can […]
South Ural State University (SUSU) scientists have proposed an innovative method for testing the effectiveness of medicines for coronavirus. According to the researchers, it is necessary to focus on the maximum coincidence of the ligand and the receptor. The results of the work have been published in the highly-rated journal "Molecules"(Q1). Despite the successful treatment […]
Apoptosis is a form of programmed cell death, which occurs in cells that are irreparably damaged or in cells infected by some viruses. This mechanism is extremely important in limiting a virus’s replication and its spread to other neighboring cells. A new paper in the journal Life presents an early review of the viral factors […]
There are several different types of electron microscopes, including the transmission electron microscope (TEM), scanning electron microscope (SEM), and reflection electron microscope (REM.) Each of these types of the electron microscope will be described in more detail in this article, including the benefits and disadvantages of each. Transmission electron microscope (TEM) The transmission electron microscope […]
By Shelley Farrar, MSc, BSc Cryo-electron microscopy, also known as Cryo-EM, is a technique for visualizing macromolecular structures which has been developed over the last two decades. It is a form of transmission electron microscopy which permits samples to be studied at cryogenic temperatures. Biological structures such as ribosomes and mitochondria from pathogens, ion channels […]
Skip to: What is Plasmonics? Applications Enhancing Raman Spectroscopy Signals Plasmonic Nanoscopy and Imaging Plasma is one of the fundamental states of matter that is generated when a neutral gas is heated or subjected to a strong electromagnetic field, both of which can result in the breaking of bonds and the stripping of electrons from […]
