Becoming a nerve cell: Timing is of the essence

Mitochondria are small organelles that provide the energy critical for each cell in our body, in particular, in the energy-demanding brain. In this week's edition of Science, a Belgian team of researchers led by Pierre Vanderhaeghen ...

Understanding congenital heart defects, one chicken at a time

Approximately 10 percent of infants are born with a congenital heart defect, with one of the most common being persistent truncus arteriosus—a hole in the heart. In a healthy baby, deoxygenated blood is pumped through a ...

DNA repeats—the genome's dark matter

Expansions of DNA repeats are very hard to analyze. A method developed by researchers at the Max Planck Institute for Molecular Genetics in Berlin allows for a detailed look at these previously inaccessible regions of the ...

A cause of possible genetic problems in mitochondria is revealed

A group of researchers from the Andalusian Centre for Molecular Biology and Regenerative Medicine (CABIMER) has revealed the importance of eliminating any excess of defective products that might have accumulated in the mitochondria, ...

Molecular guardians monitor chromosomes during cell division

One of the worst things that can happen to a cell is to end up with the wrong number of chromosomes. This can happen if something goes wrong during cell division, and it can lead to infertility, miscarriages, birth defects, ...
