How blocking cell wall formation stops bacterial cell division
Researchers still do not understand exactly how antibiotics kill bacteria. However, this understanding is necessary to develop new antibiotics. And that is precisely what is urgently needed, because bacteria are currently showing more and more resist.....»»
Modular design: New insights into protein factories in human mitochondria
The "power plants" of living cells, the mitochondria, probably evolved through endosymbiosis: A bacterium migrated into a primordial cell and eventually developed into an organelle that provides the cell with energy, among other things. Mitochondria.....»»
Why Connecticut is a model for reducing racial disparities in traffic stops—and why other states haven"t succeeded
More than 20 million drivers are stopped by police every year in the U.S. Although traffic stops are relatively routine, they can also turn deadly, particularly for minority drivers. It's why some states have started to more closely examine racial di.....»»

Advanced imaging reveals how a parasitic "kiss" alters cell metabolism
Toxoplasma gondii is a parasite responsible for toxoplasmosis, a lifelong chronic infection prevalent in about 30% of the human population. It poses little harm to healthy individuals, but can result in severe consequences for immunocompromised peopl.....»»
Team develops the first cell-free system in which genetic information and metabolism work together
The capacity of all living systems to develop, organize and sustain themselves is based upon a cyclical process in which genes and metabolism interact in parallel. While genes encode the components of metabolism, metabolism provides the energy and bu.....»»
