A team of molecular engineers at Tsinghua University, in China, has developed a new type of hydrogel that can stretch to 15 times its original size and then snap back to its original form. In their study, published in the journal Science, the group m.....»»
Novel role for metabolites in cellular metabolism discovered
Investigators led by Issam Ben-Sahra, Ph.D., associate professor of Biochemistry and Molecular Genetics, have discovered how cellular metabolism fluctuates in response to changes in levels of pyrimidines, metabolites used by cells to make DNA and RNA.....»»
Memories of mitosis: Molecular mechanism that detects defects during cell division could aid cancer treatment
Every day, our cells are hard at work multiplying. Cell division is a precise process, but sometimes this process is impaired and diseases like cancer occur. Mitosis is one of the most important phases in the cell cycle. During this phase, a cell's D.....»»
Team modulates electronic state of single-atom catalysts by CO molecular decoration for efficient methane conversion
Direct methane conversion has advantages such as low energy consumption, fewer processes, and better economics. However, it is difficult to activate methane at room temperature due to the high dissociation energy of C-H bonds of methane. Additionally.....»»
Researchers challenge the limits of molecular memory, opening the door to the development of molecular chips
Some molecules respond to external light pulses by changing their structure and holding certain states that can be switched from one to another. These are commonly referred to as photoswitches and usually have two possible states. Recently, however,.....»»
