A new plant-bacterial symbiotic mechanism promising for crop applications

... unique property in the rhizobia (2). This special character confers on it the exceptional, rare ability to form nodules on the stems of its host-plant. The plant thus acquires the possibility of fixing much higher quantities of nitrogen than those usually measured in leguminous plants which have nodules only ...

MU researcher placing eye implants in cats to help humans see

...: The Next Generation," Geordi La Forge is a blind character who can see through the assistance of special implants in his eyes. While the Star Trek character "lives" in the 24th century, people living in the 21st century may not have to wait that long for th...

Are journal rankings distorting science?

...rity of this ranking is distorting the fundamental character of journals, forcing them to focus more and more on citations and less on readers. Concerns include the fact that a bad paper may be cited because of its infamous errors and that a journal’s rank has no bearing on the quality of individual papers ...

How fish conquered the ocean

...clusters that correlate to the pelagic and benthic character of the eggs. The alteration in the function (neo-functionalization) of one of the duplicated genes (paralogues) allowed its yolk protein products to be broken down to free amino acids and thus drive hydration of the maturing eggs. The timing of these...

ASU researchers test antibacterial effects of healing clays

...ate about her subject: "Clays are as individual in character as people are in personality. They can be as old as Precambrian time (probably older, since meteorites contain clay minerals from other celestial bodies) or as young as I can make them in my lab in a few hours. They form when the chemistry, temperatu...

...articular area, called "savants", such as the main character in the film "Rain Man", are rare. Even up to the middle of the last century, exceptionally cold emotional behaviour on the part of the mother was given as the cause for autism. However, the "refrigerator mom" theory has now been refuted. The belief...

Genes involved in biofilms

...es and to phagocytosis, which explains the chronic character of these infections, states the author of the PhD. The aim of the PhD was the characterisation of the process of formation of the Staphylococcus aureus biofilm. Regulating mechanisms unknown to date The starting point for the research was the...

Envisat radar surveillance protects endangered prehistoric fish

...e a decade to reach adulthood: their slow-maturing character makes them especially vulnerable to overfishing. As toothfish numbers have crashed in heavily fished waters off Chile and Argentina, fishermen are increasingly drawn to Southern Ocean fisheries. However strict quotas have been set to preserve num...

DDT-resistant insects have additional genetic advantage that helps resistance spread

...ess in resistant insects often only look at single character traits such as number of eggs laid, and often compare resistant and susceptible lines that are genetically unrelated. "Differences in fitness therefore often correspond to differences in genetic background rather and are not due to the resistance ge...

New lead reported in tumor angiogenesis

...provide further insight into the uniquely invasive character of these cancers. He explained that cells in head and neck tumors tend to be mobile, shifting within the developing mass and possibly establishing tumor-to-endothelial cell contact to prompt angiogenesis. "We have some evidence that inflammatory fact...
