Fitness program for blood stem cells: TAZ protein protects from age-related loss of function
A well-functioning immune system is essential for protection against infections. However, with increasing age, the functioning of the immune system diminishes, which is also due to age-related damage in hematopoietic (blood) stem cells. Researchers a.....»»
Light-based therapy weakens antibiotic-resistant bacteria
Antibiotics are standard treatments for fighting dangerous bacterial infections. Yet the number of bacteria developing a resistance to antibiotics is increasing. Researchers from Texas A&M University and the University of São Paulo are overcoming th.....»»
Genomic research aids in the effort to understand how to treat deadly fungal infections
A research team led by a University of Massachusetts Amherst scientist has made a significant genetic discovery that sheds light on the use of the drug caspofungin to treat a deadly fungal infection, Aspergillus fumigatus, which kills some 100,000 se.....»»
Researchers develop new tool for targeted cell control
Thanks to new RNA vaccines, we humans have been able to protect ourselves incredibly quickly from new viruses like SARS-CoV-2, the virus that causes COVID-19. These vaccines insert a piece of ephemeral genetic material into the body's cells, which th.....»»
