NJIT engineer poised to take stem cell research a step forward

...affe, PhD, professor of biomedical engineering and chemistry at NJIT, Arinzeh will make what are known as nano-scaffolds. Scaffolds are biomaterials that stem cells attach to and, with a bit of luck, grow into the cellular building material of tissue. Under a microscope, the nano-scaffolds look like infinitesi...

Gene therapy 'turns off' mutation linked to Parkinson's disease

...trics and of molecular pharmacology and biological chemistry at the Feinberg School. The gene technique the Bohn lab developed removes a protein known as alpha-synuclein from the diseased dopamine-producing neurons that die in Parkinson's disease. Alpha-synuclein is abundant in structures known as Lewy bodies ...

MIT: Oceans are a major gene swap-meet for plankton

...only co-evolved with each other, but also with the chemistry and physics of the oceans. These three - chemistry, physics and biology - are tightly linked as a system, meaning you can't change one without altering the other two." Such work is based on the discovery that seawater is absolutely loaded with invis...

Scientists discover interplay between genes and viruses in tiny ocean plankton

...they have co-evolved with each other, and with the chemistry and physics of the oceans. The studies show that all Prochlorococcus strains are very closely related, yet they display an array of physiologies and genetic diversity, Chisholm said. "Genetic diversity is at the heart of the extraordinary stability ...

MIT chemist discovers secret behind nature's medicines

... anti-tumor agents, and fungicides. Thanks to MIT chemistry Associate Professor Catherine L. Drennan's recent crystallography sleuthing, the secret to the enzyme's enviable prowess has come to light and it appears almost anti-climactic. It's simply a matter of the size of one of its parts. "If an enzyme is a...

Carbon nanotubes that detect disease-causing mutations developed by Pitt researcher

...hods," said Star, who is an assistant professor of chemistry at Pitt. Star and his colleagues at Nanomix also tested fluorescently labeled DNA molecules in order to confirm that DNA had attached to the nanotube surfaces and was subsequently hybridized, or matched to its complementary DNA. "We have found that...
