Scientists explore genome of methane-breathing microbe
...d flexibility in M. capsulatus metabolic pathways, hinting that the bacterium is capable of responding to changes in its environment by functioning through different chemical pathways for using methane. That finding, if confirmed by later experiments, may increase the bacterium's potential as a biotech workh...Tracing a killer's path in Lou Gehrig's disease
...idence of such linkage in liver cell mitochondria, hinting that, for a reason they do not yet understand, spinal cord neurons are particular targets of the mutant protein. Such aggregation of the mutant protein with Bcl-2 could trigger the cell death machinery by either depleting Bcl-2 or even converting it ...New insights on sirtuins, involved in gene expression and aging
...t extend life boost sirtuin activity dramatically, hinting at a link between metabolism and aging through sirtuins. Sirtuins also promote genomic stability, a process that goes awry in cancer and particularly as one ages. Now, scientists at The Wistar Institute report new findings that further elucidate how...Oldest known evidence of cat taming found in Cyprus, researchers report in Science
...e was first discovered on Cyprus during the 1980s, hinting that humans had tamed these non-native animals. Foxes and other wild animals were also introduced to certain islands around this time, however. While the jawbone was evidence that humans had brought cats from the mainland, it didn't necessarily mean ...OHSU researchers discover molecular signaling system controlling aspects of embryonic development
...agues have found the Jeb protein in adult neurons, hinting that this signaling mechanism may play an essential role in neurological function. Already, an independent study has found a Jeb-like molecule in an adult worm (C. elegans), which appears to play a role in learning and memory. "The same molecules tha...Scientists find evidence for crucial root in the history of plant evolution
...fference in the cell walls of the earliest plants, hinting at the presence of lignin. In the early Devonian period, Earth is thought to have been an aggregate mass of land in the Southern Hemisphere with smaller continents in the equatorial region. Europe was near the equator, so the Rhynie Chert beds were i...Purdue research hints that birds could spread Ebola virus

David Sanders and his research group have discovered that the outer protein shell of Ebola has a biochemical structure similar to several retroviruses carried by bird...Another job discovered for a master metabolic off-switch
