Introduction on The Significance of 3D Reconstruction of DNA to Breeding Offspring
From the father to the offspring, the transmission of genetic information requires careful packaging of the DNA in the sperm. However, the way how this DNA is packaged is still unknown. In a recent study, scientists used new techniques to reveal the three-dimensional organization of DNA in mature male germ cells, revealing a critical period of development that helps explain how fathers pass genetic information to offspring. Research findings…
A Study Discover New Targets for Targeting Caliciviruses
Norovirus is highly contagious and very difficult to control. In general, the Norovirus epidemic broke out in hospitals, nursing homes, schools, hotels, and cruise ships. Calicivirus, including Norovirus and sapovirus, is also an important animal pathogen, leading to ‘cat flu’ associated with high mortality in domestic cats. In a new study, British researchers used cryo-electron microscopy to study the structure of the feline calicivirus that causes cat flu to better…
New Developed Methods to Map The Mouse Brain with Unprecedented Precision
The prior technology can make the tissue as clear and transparent as glass and expand it to several times its original size, which provides an unprecedented opportunity for the internal operation of the biopsy system. Recently, Japanese researchers mapped the cellular composition of the mouse brain with unprecedented precision. System biologist Ueda Taiji and his team at the RIKEN Biosystems Dynamics Research Center in Japan used a technique called…
Cell: New Research Reveals an Unexpected Mechanism of Action of Antibodies
In a new study, researchers from research institutions such as the University of Washington in the United States studied monoclonal antibodies which were isolated from survivors of the severe acute respiratory syndrome (SARS) or Middle East Respiratory Syndrome (MERS) caused by the coronavirus. These monoclonal antibodies reveal an alarming immune defense strategy against deadly viruses. Atomic and molecular information for these highly potent antibodies may provide new insights into these…
New Nmr Technology Enables More Sensitive Detection of Biomolecule Structures
Nuclear magnetic resonance spectroscopy is a technique used to study the structure and composition of various molecules, including proteins associated with Alzheimer’s disease and other diseases. Recently, researchers at the Massachusetts Institute of Technology have developed a method to significantly improve the sensitivity of nuclear magnetic resonance spectroscopy (NMR). Robert Griffin, a professor of chemistry at Arthur Amos Noyes, said that with this new approach, scientists should be able…
Advanced Imaging Technology Helps Reveal The Internal Features of The Tumor
Recently, researchers at the Lyon Cancer Research Center have demonstrated the potential of imaging technology to study oncology issues. Advanced imaging techniques can differentiate malignant cell populations and monitor the effectiveness of anticancer therapies. The study result is published in the Journal of Physical Review Letters, helping to design new therapeutic molecules and personalization of treatment. Despite a good understanding of the biology of cancer, 90% of experimental drugs…
New Study Analyze The High-resolution Three-dimensional Structure of The Virus Coxsackie A10
A research report published in the Journal of Nature Communications reveals the full-particle atomic resolution structure of the three different life cycles of the hand-foot-and-mouth virus Coxsackie A10 (CVA10) and the medium-resolution genomic structure of the capsid intermediate completed by the researcher in the Institute of Biophysics, Chinese Academy of Sciences, which is another important research result after they completed the study of the full-particle structure and function of the…
Award-Winning Work of the 2018 UC Berkeley Image Competition at the Cell Journal Photo Exhibition
The Molecular Imaging Center (MIC) at the University of California, Berkeley is known for its use of confocal microscopes to produce some of the most compelling images, and has a reputation for being the winner of the MIC Image Contest every year. The winning entries for the 2018 MIC Image Competition will be written in the MIC’s dream calendar and will be presented as part of the Cell Picture Show…
Nature: Tc Toxin Activation Requires Unfolding and Refolding of a β-Propeller
Bacteria have established strategies for infecting organisms and utilize them as a source of nutrients. Many bacteria use their secreted toxins to simply pierce the outer shell of the cell to destroy the cell membrane. Human pathogens such as Yersinia pestis or other bacteria from Salmonella produce a more subtle mechanism: injecting their toxic substances by using a special toxin complex. Bacterial toxins are one of the most effective…
