How a 'conductor' makes sense of chaos in early mouse embryos

Early embryonic development is tumultuous. It involves a rapid sequence of events, including cell division, differentiation, and lots of compartments moving around within each cell. Like an orchestra performance where each ...

Abnormal RNA gums up the works in brain cells, shows study

Our DNA contains four types of molecules, adenine, cytosine, thymine, and guanine—called nucleotides or bases—running along the strands that make up our chromosomes. Since there are only four, it is not unusual to find ...

Study finds why many IVF embryos fail to develop

In humans, a fertilized egg is no guarantee of reproductive success. Most embryos stop developing and perish within days of fertilization, usually because they have an abnormal number of chromosomes. Now, researchers at Columbia ...

Breakthrough in study of how epithelial cells become cancerous

Epithelial cells, which line the surfaces and organs of the body, can protect themselves against cancer by removing unhealthy or abnormal cells through a mechanism known as "apical extrusion," where the damaged cells are ...

New method targets disease-causing proteins for destruction

Scientists at the University of Wisconsin-Madison have developed a way to use a cell's own recycling machinery to destroy disease-causing proteins, a technology that could produce entirely new kinds of drugs.
