The article reports that Yi Lu and Jingjing Zhang from the University of Illinois, Urbana-Champaign have used glucose meter as a logic gate in biocomputing platforms, which produced glucose or the reduced form of nicotinamide adenine dinucleotide (NADH) in response to biological substance.

Reports on the findings of a chemical research conducted by scientists fro the Dartmouth Medical School regarding an unidentified metabolic route to the oxidized form of nicotinamide adenine dinucleotide (NAD). Enzyme production in yeast without the required gene described in NAD pathways.

Reports on the proposal of the dynamics and mechanism of Alzheimer's disease by researchers from Cornell and Columbia Universities. Claim that the enzyme Beta-amyloid-binding alcohol dehydrogenase (ABAD) facilitates the process for Beta-amyloid to harm neurons or mitochondria in neural cells; Observation of the formation of a complex with ABAD in the mitochondria of nerve cells to distort enzymes which eliminates its binding of nicotinamide adenine dinucleotide.
