Dental researchers answer key enamel question
...elogenin by crystallizing it. Crystallography is a traditional
method of exploring molecular structure. After a year, the researchers were unable to obtain amelogenin crystals. Instead, their efforts produced what looked, under a microscope, like long, fettucine-like fibers. The fibers consisted of chains of ame...
Researchers make surprise discovery that some neurons can transmit three signals at once
...apses cooperate to activate NMDA receptors. In the traditional
sense, when inhibitory synapses are mature, they would never release glutamate, nor would they be able to depolarize a cell, both of which are required for NMDA receptor activation. But, as if by design, during the exact period when the auditory brai...

aircraft or satellite approaches, but the new methods are sensitive to its high water content. In addition, the aircraft-based analysis discovered that ginger reduces the amount of nitrogen in the Metrosideros forest canopy--a discovery that was late...
Study: Soap and water work best in ridding hands of disease viruses

hand washing with soap and water throughout each day. Researchers first had volunteers clean their hands and then contaminated their hands with Serratia marcescens and MS2 bacteriophage. Those are, respectively, a harmless bacterium and virus compara...
Chemical engineer Kao explores antibiotic synthesis with DNA chips
...cer that's equivalent to 20 years of work with the traditional

one gene-one transcript model. Furthermore, the SATs tended to be poly(A)-negative and enriched in the nucleus, which strongly suggests a functional role for these transcripts in gene regulation. Abe and Kiyosawa also evaluated four Arabidopsis SAT ...
