Learn Organic Chemistry - Radical Halogenation

If you are planning to become a biologist, a key required course is organic chemistry and in that class one of the reactions you have to memorize is radical halogenation. In this reaction a halogen atom (e.g. chlorine, bromine, iodine) bonds to a carbon and replaces the hydrogen that was formerly bonded to that carbon. When chlorine is used, the process is called radical chlorination. The music video below was created at Columbia University to help students memorize this reaction.

New genetic discovery could regulate plant growth

"The gene, named GIGANTUS1 (or GTS1 for short), is a member of a protein family that controls seed germination, growth, and biomass accumulation in plants. Essentially, it helps plants regulate growth. "Plants must tightly regulate their cellular functions to grow and cope with constantly changing environmental conditions, but exactly how this occurs is largely unknown," says Simeon Kotchoni, an assistant professor of biology at Rutgers–Camden."

New technique for identifying gene-enhancer

With the new SIF-seq technique, mouse embryonic stem cells can be used to identify human embryonic stem cell enhancers even when the human enhancers are not present in the mouse genome.

A team of researchers from Duke-NUS Graduate Medical School have discovered a protein complex that disrupts the process known as dedifferentiation, known to promote tumor development.
Dedifferentiation (reversion) is a process that leads progenitor or  to become 'ectopic neural stem cells' which causes tumors. By detecting this protein complex, Duke-NUS researchers have shed light on a process that inhibits  and gives hope for the discovery of therapies and treatments that target tumor prevention through this pathway.
