A potential biological cause for sudden infant death syndrome

...six months of life. "We think that the control systems for vital or homeostatic functions reach full maturity only towards the end of the first year of life," Kinney says. The researchers note that despite the national Back to Sleep campaign, which urges caregivers to put babies to bed on their backs...

Theory of oscillations may explain biological mysteries

...know that even a weak coupling between oscillating systems can yield synchronized oscillations, a phenomenon that was studied with pendulums by the seventeenth century Dutch mathematician Christiaan Huygens. Biologists have only in recent years started to explore the implications for their subject. But it is...

Fight weeds with plant pathogens

...ative weed control options for areas or production systems where the use of chemical herbicides is not permitted or feasible," said Erin Rosskopf, USDA, Agricultural Research Service, Fort Pierce, FL. "Plant pathogens may also be used when the herbicide selection or usage must be rotated with other control m...

Genome info from 'plant destroyers' could save trees, beans and chocolate

...eing driven to evolve by pressure from the defense systems of the pathogens' host plants," said Virginia Bioinformatics Institute's Brett Tyler, the project's principal investigator. "The Phytophthoras, in addition to their great economic importance, are fascinating organisms with very distinct and interest...

Two nerve cells in direct contact

...eveloping navigating robots and driving assistance systems rely on simple and robust algorithms such as those realized by nature in insects. The mechanisms of optical flow field analysis are supremely suitable for technical implementation. As part of two projects supported by the Federal Ministry for Educati...

Discovery in the evolution of the immune system absorbing cells

... so that we can understand not only how the immune systems of fish and amphibians work but also the origin and composition of the immune systems of humans and mammals". The work concludes that there is an evolutionary relationship between macrop...

New brain-chemistry differences found in depressed women

...ings add the mu-opioid system to the list of brain systems that appear to be altered in depression. Others include the corticotrophin-releasing hormone system, and those involved in noradrenaline, dopamine and serotonin production. "Further research on these differences, and their relationship to patient...

Sequencing of the oyster mushroom genome

...the natural environment, may be used for designing systems to enable the elimination of these contaminants from the environment. The oyster mushroom is also a fungus the cultivation of which is widespread and so the study of its genetic organisation can give pointers to what is needed for many mushrooms n...

Transplanted photoreceptor precursor cells restore visual function in mice with retinal degeneration

...s of research using animal models and cell culture systems will still be needed before transplantation can be considered ready for testing in humans. Restoring visual function in animals is an important advance, but the scientists caution that it shouldn't be considered the same as restoring vision in h...
