When neurons are damaged by degenerative disease or injury, they have little, if any, ability to heal on their own. Restoring neural networks and their normal function is therefore a significant challenge in the field of tissue engineering. Prof. Orit Shefi and doctoral student Reut Plen from the Kofkin Faculty of Engineering at Bar-Ilan University have developed a novel technique to overcome this challenge using nanotechnology and magnetic manipulations, one of the most innovative approaches to creating neural networks.
UC San Diego researchers have for the first time discovered a pattern of DNA mutations that links bladder cancer to tobacco smoking. The work could help researchers identify what environmental factors, such as exposure to tobacco smoke and UV radiation, cause cancer in certain patients. It could also lead to more customized treatments for a patient’s specific cancer.

It increased pain tolerance in mice, lowered their sensitivity to pain and provided months of pain relief without causing numbness.
The heart cannot regenerate new tissue, because cardiomyocytes, or heart muscle cells, do not divide after birth. However, researchers have now developed a shape memory polymer to grow cardiomyocytes. Raising the material’s temperature turned the polymer’s flat surface into nanowrinkles, which promoted cardiomyocyte alignment. The research is part of the growing field of mechanobiology, which investigates how physical forces between cells and changes in their mechanical properties contribute to development, cell differentiation, physiology, and disease.

Researchers at the University of California San Diego have identified new mechanisms in neurons that cause Alzheimer’s disease. In particular, they discovered that changes in the structure of chromatin, the tightly coiled form of DNA, trigger neurons to lose their specialized function and revert to an earlier cell state. This results in the loss of synaptic connections, an effect associated with memory loss and dementia.

Proteins are the building blocks of life and scientists have long studied how to improve them or design new ones. Traditionally, new proteins are created by mimicking existing proteins or manually editing their amino acids. This process is time-consuming, and it is difficult to predict the impact of changing an amino acid. In APL Bioengineering, researchers explore how to create new proteins by using machine learning to translate protein structures into musical scores, presenting an unusual way to translate physics concepts across domains.
