Research on Worms Yields Clues on Aging

...hers alsodemonstrated that anticonvulsants did not extend life by protecting theworms from pathogenic bacteria in their environment.Ethosuximide and trimethadione did, however, significantly delayage-related declines in neuro-muscular activity. Treated wormscontinued to display the youthful traits of fast b...

Learning to fight an adversary that won't stay down

...our understanding of the activity of microbes must extend beyond the newspaper headlines reporting outbreaks of these "superbugs," so that we can put the role of these organisms in the proper evolutionary perspective. This subject, and antibiotic resistance in particular, has fascinated Davies since he bega...

Experiments provide proof of how traveling in groups protects insects

...ular marching packs stretch several miles wide and extend 10 miles or so in length. And they can travel a mile or so a day. Why such groups of insects form has mystified humans for thousands of years. One firmly held belief was that God was punishing men and women for their sins. A more recent, scientific ...

Vital step in cellular migration described by UCSD medical researchers

.... If Rac were active throughout the cell, it would extend protrusions in all directions, in essence keeping the cell in one place. Until now, researchers have had limited understanding of the molecular mechanism that inhibits Rac activity in the back of the cell, to maintain directional movement. In labora...

New RNA polymerase discovered in plants

...ome speculation that this form of polymerase might extend twice as far back in evolution,' Pikaard said. Pikaard said that it is strange that so far this kind of polymerase has been found only in plants. "Why would plants only have these?" he questioned.

Liposome finding implies electrical effect on cell development

...microtubules were observed to immediately form and extend from the phospholipid balloon, like a seed putting forth a stalk or root. Hayes believes that the phenomena may have significant implications for both cellular biology and for nanotechnology. "This finding might not only be important in its applicat...
