What controls stickiness of 'smart' chromosomal glue

Researchers have a new understanding of the process cells use to ensure that sperm and eggs begin life with exactly one copy of each chromosome ?a process that must be exquisitely regulated to prevent problems such as miscarriages and mental retardation. The new work reveals how gluelike protein complexes release pairs of chromosomes at precisely the moment of meiosis ?the specialized cell divisi...

Neuron cell stickiness may hold key to evolution of the human brain

The stickiness of human neurons may have been a key factor in why the human brain evolved beyond the brains of our primate relatives. In a study comparing the genomes of humans, chimpanzees, mice and other vertebrates, researchers at the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) and Joint Genome Institute (JGI) found a strikingly high degree of genetic diffe...
