NJIT engineer poised to take stem cell research a step forward

...e New Jersey Commission on Spinal Cord Research, a state agency that funds spinal cord research. She will use the grant to build a laboratory to test if stem cells taken from adult bone marrow can be made to turn into neurons. If her research shows that the cells can turn into neurons -- the nerve cells in...

Scientists develop a way to make the deadliest toxin known even more toxic

...fold activation of a protease was referred to as a state of "superactivation." Proteases are enzymes that act as cellular catalysts, breaking up proteins into smaller elements such as amino acids and reducing the amount of energy needed for the activation. The study was released in an advanced online ver...

Movement of chromosome in nucleus visualized

Aging cells, aging body: Fresh evidence for a connection

... Over time, cells lose their ability to divide, a state known as replicative senescence. The new research, published in an advanced online edition of Science, is the first to quantify the presence of replicatively senescent cells in any species. "For 40 years, we've known about replicative senescence," s...
