Microscopic sea creatures provide foundation for gas sensors and other devices
... research is needed to learn how to manipulate the genome
of the diatom. Since scientists already know how to culture diatoms in large volumes, harnessing the diatom genetic code could allow mass-production of complex and tailored microscopic structures. Sandhages colleagues, Prof. Nils Krger (Georgia Tech...
Plants' management of nutrient suggests environmental remedies
...relatively short life cycle of eight weeks and its genome
has been completely sequenced. By tracking the glow of the jellyfish molecules, the researchers learned that CAS plays a number of roles in plants. The scientists initially thought it simply monitored changes in levels of dissolved calcium that ent...

Despite their heft, many dinosaurs had surprisingly tiny genomes
...d. So say scientists who've linked bone cell and genome

sizes of 31 species of extinct dinosaurs and birds, whose bone cells can be measured from the fossil...
Plant size morphs dramatically as scientists tinker with outer layer
...a small plant related to cabbage and mustard whose genome
has been decoded. Over the years, the researchers have built up a whole tool kit, learning how to add and subtract genes in order to determine form and function. Among their discoveries is a class of dwarf plants whose size is about one-tenth the siz...

Gene sequencing advance will aid in biomass-to-biofuels conversion
...ls. "We have sequenced and assembled the complete genome
of Pichia stipitis, a native xylose-fermenting yeast," says Thomas Jeffries, research microbiologist at FPL and a professor of bacteriology at the University of Wisconsin-Madison. The results of this research project will be published in the scientif...

sequence of R. felis shows inconsistencies that could place it in either the spotted fever or typhus groups. The new classification system highlighted in the study includes the addition of a fourth lineagetransitional group rickettsiathat provides a ...
Study examines genetic risk factors for Alzheimer's disease
